Effects of gender affirming hormone treatment in transgender individuals - a retrospective cohort study.

PURPOSE: Gender affirming hormone treatment (GAHT) results in measurable changes to anthropomorphic, biochemical and hormonal variables that are important to patients and their health care professionals to guide treatment. This study sought to quantify changes which occur in response to initiation of GAHT. METHODS: We performed a retrospective cohort study of outcomes in transgender and gender diverse (TGD) patients starting GAHT. The primary outcome was proportion of patients and time required to achieve optimal hormone levels after commencement of GAHT. Additional analyses were performed to assess whether clinical and biochemical factors were associated with likelihood of achieving target hormone levels. RESULTS: 345 patients were included. Among 154 transmasculine individuals, 116 (75%) achieved a testosterone level >10 nmol/L during follow-up at a median of 4-months (IQR 4-9). No clinical or biochemical factors were significantly associated with likelihood of reaching therapeutic testosterone concentrations in transmen. Among 191 transfeminine individuals, 131 (72%) achieved a testosterone level <2.0 nmol/L during follow-up at a median of 4-months (IQR 3-9). Factors associated with increased likelihood of testosterone suppression were use of subdermal estradiol implants as well as cyproterone acetate as an androgen antagonist. Changes in differing directions were observed during repeated measures of lipids, liver function, and blood count between transmasculine and transfeminine individuals, reflecting the important effects of testosterone and estradiol on biochemical tests ordered as part of routine clinical care. CONCLUSION: Most TGD patients achieve target testosterone levels within 9 months of GAHT initiation. Adverse effects of GAHT are rare, and are usually mild.

Effect of cyproterone acetate/ethinyl estradiol combination on periodontal status and high-sensitivity C-reactive protein levels in women with polycystic ovary syndrome: a cross-sectional study.

OBJECTIVE: Polycystic ovary syndrome (PCOS) is widely reported among young females, and anti-androgens are used for treating hirsutism and acne in these patients. The protective effects of myo-inositol, oral contraceptives, and insulin sensitizers have been reported on the periodontium and high-sensitivity C-reactive protein (hsCRP) levels in PCOS females. However, cyproterone acetate/ethinyl estradiol (CPA/EE) has not yet been studied. This cross-sectional study explores the periodontal status and systemic inflammation in PCOS women on CPA/EE drug combination compared to females not on medication. METHOD AND MATERIALS: A total of 150 participants were enrolled into three groups: 50 newly diagnosed PCOS females not on medication (N-PCOS); 50 PCOS females consuming CPA/EE combination for the last 6 months (PCOS+CPA/EE); and 50 systemically healthy females (control group). Anthropometric, biochemical, periodontal parameters, and health-related quality of life questionnaires were recorded. RESULTS: N-PCOS and PCOS+CPA/EE groups showed a nonsignificant difference in hsCRP levels, Gingival Index, bleeding on probing, waist circumference, and waist-hip ratio (P > .05). Gingival thickness and keratinized tissue width were significantly greater in the PCOS+CPA/EE than the N-PCOS group (P ≤ .05); however, these were comparable with the control group (P > .05). Regression analysis showed significant association of bleeding on probing with Gingival Index, clinical attachment level, and hsCRP (P ≤ .05). CONCLUSIONS: CPA/EE combination does not influence the periodontal and systemic inflammatory status in PCOS females, as similar levels of local and systemic inflammation were observed in CPA/EE consumers compared with PCOS females not on medication. However, it might play a role in increasing gingival thickness and keratinized tissue width in these patients.

Effects and plasma proteomic analysis of GLP-1RA versus CPA/EE, in combination with metformin, on overweight PCOS women: a randomized controlled trial.

PURPOSE: Polycystic ovary syndrome (PCOS) is characterized by reproductive dysfunctions and metabolic disorders. This study aims to compare the therapeutic effectiveness of glucagon-like peptide-1 receptor agonist (GLP-1RA) + Metformin (Met) versus cyproterone acetate/ethinylestradiol (CPA/EE) + Met in overweight PCOS women and identify potential proteomic biomarkers of disease risk in women with PCOS. METHODS: In this prospective, open-label randomized controlled trial, we recruited 60 overweight PCOS women into two groups at a 1:1 ratio to receive CPA/EE (2 mg/day: 2 mg cyproterone acetate and 35-µg ethinylestradiol,) +Met (1500 mg/day) or GLP-1 RA (liraglutide, 1.2-1.8 mg/day) +Met (1500 mg/day) for 12 weeks. The clinical effectiveness and adverse effects were evaluated, followed by plasma proteomic analysis and verification of critical biomarkers by ELISA. RESULTS: Eighty(80%) patients completed the study. Both interventions improved menstrual cycle, polycystic ovaries, LH(luteinizing hormone) and HbA1c(hemoglobin A1c) levels after the 12-week treatment. GLP-1RA + Met was more effective than CPA/EE + Met in reducing body weight, BMI (Body Mass Index), and waist circumference, FBG(fasting blood glucose), AUCI(area under curve of insulin),TC (Total Cholesterol), IL-6(Interleukin-6) and improving insulin sensitivity, and ovulation in overweight women with PCOS, with acceptable short-term side effects. CPA/EE + Met was more effective in improving hyperandrogenemia, including T(total testosterone), LH, LH/FSH(Luteinizing hormone/follicle-stimulating hormone), SHBG(sex hormone-binding globulin) and FAI (free androgen index). By contract, GLP-1RA+Met group only improved LH. Plasma proteomic analysis revealed that the interventions altered proteins involved in reactive oxygen species detoxification (PRDX6, GSTO1, GSTP1, GSTM2), platelet degranulation (FN1), and the immune response (SERPINB9). CONCLUSIONS: Both CPA/EE+Met and GLP-1RA + Met treatment improved reproductive functions in overweight PCOS women. GLP-1RA + Met was more effective than CPA/EE + Met in reducing body weight, BMI, and waist, and improving metabolism, and ovulation in overweight women with PCOS, with acceptable short-term side effects. CPA/EE + Met was more effective in reducing hyperandrogenemia. The novel plasma biomarkers PRDX6, FN1, and SERPINB9, might be indicators and targets for PCOS treatment.

Different kinds of oral contraceptive pills in polycystic ovary syndrome: a systematic review and meta-analysis.

OBJECTIVE: To compare between different combined oral contraceptive pills (COCPs) as part of the update of the International Evidence-Based Guidelines on the Assessment and Management of polycystic ovary syndrome (PCOS). DESIGN: A systematic review and meta-analysis was performed, Prospero CRD42022345640. METHODS: MEDLINE, EMBASE, All EBM, CINAHL, and PsycINFO was searched on July, 8, 2022, for studies including women with PCOS, comparing 2 different COCPs in randomized controlled trials. RESULTS: A total of 1660 studies were identified, and 19 randomized controlled trials (RCTs) were included.Fourth-generation COCP resulted in lower body mass index (BMI) (mean difference [MD] 1.17 kg/m2 [95% confidence interval {CI} 0.33; 2.02]) and testosterone (MD 0.60 nmol/L [95% CI 0.13; 1.07]) compared with third-generation agents, but no difference was seen in hirsutism.Ethinyl estradiol (EE)/cyproterone acetate (CPA) was better in reducing hirsutism as well as biochemical hyperandrogenism (testosterone [MD 0.38 nmol/L {95% CI 0.33-0.43}]) and BMI (MD 0.62 kg/m2 [95% CI 0.05-1.20]) compared with conventional COCPs.There was no difference in hirsutism between high and low EE doses. No evidence regarding natural estrogens in COCP was identified. CONCLUSION: With current evidence, combined regimens containing an antiandrogen (EE/CPA) may be better compared with conventional COCPs in reducing hyperandrogenism, but EE/CPA will not be recommended as a first-line COCP treatment by the pending PCOS guideline update, due to higher venous thrombotic events (VTE) risk in the general population. Later-generation progestins offer theoretical benefits, but better evidence on clinical outcomes is needed in women with PCOS. TRIAL REGISTRATION: The protocol for the systematic review was registered prospectively in Prospero, CRD42022345640.

Circulating follistatin concentrations in adolescent PCOS: Divergent effects of randomized treatments.

Purpose: Follistatin is a glycoprotein that represses members of the transforming growth factor-ß superfamily including activin. Higher follistatin levels have been associated with an increased risk for type 2 diabetes and with polycystic ovary syndrome (PCOS). In non-obese adolescent girls with PCOS, insulin sensitization results in a healthier endocrine-metabolic outcome than oral contraception (OC); we assessed whether those differences are underscored by changes in serum follistatin concentrations. Methods: Circulating follistatin, endocrine-metabolic markers and hepato-visceral fat were measured longitudinally in 72 girls with PCOS [age, 16 years; body mass index (BMI), 23 Kg/m2] randomized to receive PioFluMet [pioglitazone (7.5 mg/d), metformin (850 mg/d) and flutamide (62.5 mg/d), n=17]; EE-CA [an OC containing 35 µg ethinylestradiol (EE) and 2 mg cyproterone acetate (CA), n=17]; SPIOMET [Spironolactone (50 mg/d), pioglitazone (7.5 mg/d) and metformin (850 mg/d), n=18], or EE-LNG [an OC containing 20 µg EE and 100 mg levonorgestrel (LNG), n=20]. Twenty-eight age- and BMI-matched healthy girls served as controls. Results: Pre-treatment follistatin levels were similar in PCOS and controls. OCs raised serum follistatin after 6 months (6.8-fold vs 2.5-fold for EE-CA and EE-LNG, respectively). Neither SPIOMET nor PioFluMet changed follistatin levels. Follistatin correlated negatively with high-molecular weight adiponectin and positively with mean serum insulin concentrations during an oral glucose tolerance test at baseline, and with liver fat after 6 months. Conclusion: In girls with PCOS, follistatin levels rise significantly after 6 months on OCs and this increase associates to a worsening of markers of insulin resistance and to changes in liver fat.

Changes in Serum Testosterone and Adrenal Androgen Levels in Transgender Women With and Without Gonadectomy.

BACKGROUND: Initiating feminizing gender-affirming hormone therapy (GAHT) in transgender women causes a steep decline in serum testosterone. It is unknown if testosterone concentrations change further and whether adrenal androgen levels change during feminizing GAHT and after gonadectomy. This limits clinical decision making in transgender women with symptoms attributed to GAHT or gonadectomy. METHODS: Transgender women (n = 275) initiating estradiol and cyproterone acetate (CPA) were included at baseline, and had follow-up visits after 3 months, 12 months, and 2 to 4 years. During follow-up, 49.5% of transgender women underwent a gonadectomy. Total testosterone (TT), dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEAS), and androstenedione (A4) were measured using liquid chromatography tandem mass spectrometry. RESULTS: After 3 months of GAHT, mean TT, calculated free testosterone (cFT), and A4 decreased by 18.4 nmol/L (95% CI, -19.4 to -17.4, P < 0.001 [ie, -97.1%]), 383 pmol/L (95% CI, -405 to -362, P < 0.001 [ie, -98.3%]), and 1.2 nmol/L (95% CI, -1.4 to -1.0, P < 0.001 [ie, -36.5%]), respectively, and remained stable thereafter. DHEA and DHEAS decreased by 7.4 nmol/L (95% CI, -9.7 to -5.1 [ie, -28.0%]) and 1.8 µmol/L (95% CI, -2.2 to -1.4 [ie, -20.1%]), respectively, after 1 year and did not change thereafter. After gonadectomy, CPA therapy is stopped, which induced no further change in TT, cFT, DHEA, DHEAS, and A4 compared with those who did not undergo gonadectomy. CONCLUSIONS: Our findings confirm that after an initial drop, testosterone levels in transgender women remain stable. Adrenal androgens decrease in the first year of CPA and estrogen supplementation and remain unchanged after gonadectomy. Androgens did not change after gonadectomy and cessation of CPA. Correlates with clinical symptoms remain to be elucidated.

Gender confirmation hormonal treatment use in young Polish transgender binary and non-binary persons.

INTRODUCTION: Gender confirmation hormonal treatment (GCHT) is a cornerstone of medical treatments for persistent gender dysphoria, which is expected and required by many transgender binary and non-binary individuals. Many protocols have been published, and the qualification process is guided by the World Professional Association for Transgender Health Standards of Care. The standards and other documents such as the Endocrine Society Clinical Practice Guideline provide gender confirmation hormonal care also for minors. However, the issue of starting these treatments in younger populations is still marked by controversy. This preliminary study aimed to inquire into GCHT (medications used, timing of its initiation, its tolerance, and sources of information on the treatment) in a convenience sample of young Polish transgender binary and non-binary persons. MATERIAL AND METHODS: A total of 166 adult transgender participants answered our online questionnaire between November 2020 and December 2021. The population was divided into 2 groups: assigned male at birth (AMB, n = 37) and assigned female at birth (AFB, n = 126). Subsequently, division into binary and non-binary was applied to these groups. RESULTS: Most patients (91.9% AMB and 92.2% AFB) did not use gender confirmation medical treatments before the age of 18 years. The most common medication used for GCHT before the age of 18 was cyproterone acetate for AMB and testosterone for AFB. When asked about their opinion on the timing (age) of initiating GCHT, 73.1% of the AMB and 59.2% of the AFB participants shared the view that it had been initiated much too late. By far the most common source of information on GCHT and gender confirmation surgery (GCS) was the Internet (92.2%). CONCLUSIONS: These treatments (including pubertal blocking) seem to be rarely commenced in Poland before the age of 18 years. In adults, treatment consists mostly of either testosterone or oestradiol, and cyproterone acetate and, more seldom, spironolactone are used as antiandrogens in persons assigned male at birth. In turn, gonadotropin-releasing hormone agonists are barely used at all. Specialists need to be more aware that withholding treatment in minors with gender dysphoria is not a health-neutral option. Gonadotropin-releasing hormone agonists should also be more often considered as an alternative to cyproterone acetate in the context of long-term safety.

Hormone Concentrations in Transgender Women Who Self-Prescribe Gender Affirming Hormone Therapy: A Retrospective Study.

BACKGROUND: Self-prescribed gender-affirming hormone therapy (GAHT) is common practice among transgender women, especially in resource-limited countries, yet the effectiveness of each GAHT regimen to achieve female range sex hormone concentrations is not known. AIM: To describe the use and sex hormone concentrations of various GAHT regimens among transgender women who self prescribe in Thailand. METHODS: This was a retrospective study in a community-based setting. Five hundred and 27 records of transgender women taking GAHT who were receiving care at a community health center between January 1, 2018, and December 31, 2020 were included for the analysis. MAIN OUTCOME MEASURES: Blood total testosterone and estradiol concentration after at least a 6-month period of GAHT. RESULTS: Multiple GAHT regimens were identified including oral estradiol valerate (EV), transdermal 17ß-estradiol gel, injectable EV with hydroxyprogesterone caproate, injectable estradiol benzoate with progesterone, oral EV with cyproterone acetate (CPA), and oral contraceptive pills (OCPs). The most common GAHT regimen used by 49.1% of the participants was OCPs that contained 0.035 mg of ethinyl estradiol and 2 mg of CPA. Only 25.2% of this group had female range testosterone concentrations (<50 ng/dL). Oral EV and CPA were used by 23.1% of the participants. Most of them used 12.5 mg of CPA and 47.7% of this group had female range testosterone concentrations. There was no statistical significance between mean testosterone concentrations in CPA 12.5 and 25 mg groups, (P = .086). CLINICAL IMPLICATIONS: The inadequate sex hormone levels found in these commonly self-prescribed GAHT regimens provide information regarding the efficacy and safety of GAHT regimens for health care providers working with transgender women in a community-based setting. STRENGTHS AND LIMITATIONS: This study reflected a real-world situation and provided hormonal profiles among transgender women taking self-prescribed GAHT. However, issues in recall, medical literacy, and adherence to the medication may limit the results. CONCLUSION: Combined hormonal contraceptive pill was a commonly used GAHT regimen in Thai transgender women who self prescribe GAHT. However, this regimen was not effective to decrease testosterone concentrations to the recommended range of less than 50 ng/dL. Overall, self-prescription of GAHT does not appear to be effective in reaching target sex hormone concentrations. Including health care providers in the prescription and monitoring of GAHT may be a more effective approach in the delivery of GAHT. Salakphet T, Mattawanon N, Manojai N, et al.

The effect of transdermal gender-affirming hormone therapy on markers of inflammation and hemostasis.

BACKGROUND: Cardiovascular risk is increased in transgender persons using gender-affirming hormone therapy. To gain insight into the mechanism by which sex hormones affect cardiovascular risk in transgender persons, we investigated the effect of hormone therapy on markers of inflammation and hemostasis. METHODS: In this exploratory study, 48 trans women using estradiol patches plus cyproterone acetate (CPA) and 47 trans men using testosterone gel were included. They were between 18 and 50 years old and did not have a history of cardiovascular events. Measurements were performed before and after 3 and 12 months of hormone therapy. RESULTS: After 12 months, in trans women, systemic and endothelial inflammatory markers decreased (hs-CRP -66%, (95% CI -76; -53), VCAM-1-12%, (95% CI -16; -8)), while platelet activation markers increased (PF-4 +17%, (95% CI 4; 32), ß-thromboglobulin +13%, (95% CI 2; 24)). The coagulation marker fibrinogen increased transiently, after 3 months (+15%, (95% CI 1; 32)). In trans men, hs-CRP increased (+71%, (95% CI 19; 145)); platelet activation and coagulation markers were not altered. In both trans women and trans men, leptin and adiponectin changed towards reference values of the experienced gender. CONCLUSIONS: Platelet activation and coagulation marker concentrations increased in trans women using transdermal estradiol plus CPA, but not in trans men using testosterone. Also, concentrations of inflammatory markers decreased in trans women, while hs-CRP increased in trans men. Our results indicate that hormone therapy may affect hemostasis in transgender persons, which could be an underlying mechanism explaining the increased cardiovascular risk in this population.

Tratamiento hormonal de la pedofilia: ¿puede curar la pedofilia con la castración química? / Pedophilia hormonal therapy: can pedophilia be cured with chemical castration

Históricamente la sociedad ha rechazado el abuso sexual de menores de 13 años, dictándose leyes al respecto. La justicia luego de un debido proceso condenaba al victimario con reclusión incluso hasta la década del 70-80, con orquiectomía. Los adelantos en neurobiología, endocrinología, sicofarmacología y sicología se consideraron las bases para tratar al pedófilo y someterlo a libertad condicional, ahorrándose el costo financiero de la reclusión de por vida. Diversos países dictaron leyes contra la conducta pedófila. En dicha legislación ejerció gran influencia la promulgación en EE.UU. (estado de Washington "sobre el ofensor sexual" y el dictamen de la Corte Suprema en 1997 en el juicio de Kansas vs Hendricks). En Chile en los 90 el caso del pedófilo apodado "Zacarach" sacó a la luz pública el tema que no se quería ver. En esa fecha se presentó al parlamento un proyecto de Ley para "curar" la pedofilia con acetato de Medroxiprogesterona imitando legislación de EE.UU. Causó sorpresa en el medio endocrinológico que se usara terapia hormonal como "cura" de la pedofilia. Se ha utilizado en varios países la castración química producida por gestágenos o agonístas del GnRH más antiandrógenos (acetato de Ciproterona), para inhibir la secreción y acción de la testosterona disminuyendo líbido y erección. No se ha demostrado que exista curación de la orientación pedófila y existen dudas de la prevención primaria y secundaria de la pedofilia. Pese al adelanto tecnológico en neurociencias para estudio de las zonas vinculadas a la sexualidad, aún no existen marcadores que permitan diagnosticar o pronosticar futuros resultados de la terapia. El tratamiento médico de la pedofilia no garantiza curación ni prevención del delito pedofílico.

Historically, society has rejected sexual abuse of children under 13, with there having been laws enacted in this regard. The judicial system, after a due process, condemned the perpetrator with reclusion and even up until the decades of the 70s and 80s with orchiectomy. Advances in neurobiology, endocrinology, psychopharmacology and psychology were considered the basis for treating the pedophile and putting them on probation, saving the financial cost of imprisonment for life. Multiple countries have enacted laws against pedophilic behaviour. Such legislation was greatly influenced by the enactment in the USA (state of Washington "on the sex offender" and the ruling of the Supreme Court in 1997 in the trial of Kansas against Hendricks). In Chile in the 90s, the case of a pedophile nicknamed "Zacarach" brought to light an issue that nobody wanted to see. Around that time, a bill was presented to Parliament to try and "cure" pedophilia with Medroxyprogesterone acetate, imitating US legislation. It was a surprise in the endocrinological world that hormonal therapy would be used as a "cure" for pedophilia. Chemical castration produced by gestagens or GnRH agonists plus antiandrogens (Cyproterone acetate) has been used in several countries to inhibit the secretion and action of testosterone, reducing libido and erection. It has not been proven that there is a cure for pedophile orientation and there are doubts about the primary and secondary prevention of pedophilia. Despite technological advances in neurosciences for the study of the zones pertaining to sexuality, there are still no indicators that allow for diagnosis or prediction of future results of therapy. The medical treatment of pedophilia does not guarantee cure or prevention of pedophilic crime.

Bloodletting has no effect on the blood pressure abnormalities of hyperandrogenic women taking oral contraceptives in a randomized clinical trial.

Normoferritinemic women with functional hyperandrogenism show a mild iron overload. Iron excess, hyperandrogenism, and cardioautonomic dysfunction contribute to blood pressure (BP) abnormalities in these patients. Furthermore, combined oral contraceptives (COC) prescribed for hyperandrogenic symptoms may worse BP recordings. Iron depletion by phlebotomy appears to lower BP in other acquired iron overload conditions. We aimed to determine the effect of iron depletion on the office BP, ambulatory BP monitoring, and frequency of hypertension in patients with functional hyperandrogenism submitted to standard therapy with COC. We conducted a phase 2 randomized, controlled, parallel, open-label clinical trial (NCT02460445) in adult women with functional hyperandrogenism including hyperandrogenic polycystic ovary syndrome and idiopathic hyperandrogenism. After a 3-month run-in period of treatment with 35 µg ethinylestradiol plus 2 mg cyproterone acetate, participants were randomized (1:1) to three scheduled bloodlettings or observation for another 9 months. Main outcome measures were the changes in office BP, 24-h-ambulatory BP, and frequency of hypertension in both study arms. From June 2015 to June 2019, 33 women were included in the intention-to-treat analyses. We observed an increase in mean office systolic BP [mean of the differences (MD): 2.5 (0.3-4.8) mmHg] and night-time ambulatory systolic BP [MD 4.1 (1.4-6.8) mmHg] after 3 months on COC. The percentage of nocturnal BP non-dippers also increased, from 28.1 to 92.3% (P < 0.001). Office and ambulatory BP did not change throughout the experimental period of the trial, both when considering all women as a whole or as a function of the study arm. The frequency of the non-dipping pattern in BP decreased during the experimental period [OR 0.694 (0.577-0.835), P < 0.001], regardless of the study arm. Decreasing iron stores by scheduled bloodletting does not override the BP abnormalities caused by COC in women with functional hyperandrogenism.

The comparative effectiveness of 55 interventions in obese patients with polycystic ovary syndrome: A network meta-analysis of 101 randomized trials.

BACKGROUND: Polycystic ovary syndrome (PCOS) affects up to 18% of reproductive-age females. The prevalence of obesity in PCOS patients reaches up to 80%, which is 2-fold higher than the general population. OBJECTIVE: The present study aimed to compare the effectiveness of 55 pharmacological interventions across 17 different outcomes in overweight/obese PCOS patients with hyperandrogenism manifestations for both short- and long-term follow-ups. A comprehensive literature search was performed on PubMed, Scopus, Embase, Science Direct, Web of Science, and Cochrane CENTRAL for randomized controlled trials comparing any conventional pharmacological intervention as a monotherapy or a combination in overweight/obese patients with polycystic ovary syndrome and hyperandrogenism manifestations. Extracted data included three main parameters; I. Anthropometric parameters (BMI, Waist and Hip circumferences, and Waist/HIP ratio), II. Hormonal parameters (FSH, LH, FSG, SHBG, Estradiol, Total Testosterone, Free testosterone, DHEAS, Androstenedione), and III. Metabolic parameters (Total Cholesterol, LDL-C, HDL-C, Triglycerides, Fasting glucose, Fasting glucose, HOMA-IR). Critical appraisal and risk of bias assessments were performed using the modified Jadad scale, and the overall quality of this network meta-analysis was evaluated according to the CINeMA framework. We performed both a pairwise meta-analysis and a network meta-analysis to evaluate the effect sizes with 95% CI, and we calculated the surface under the cumulative ranking curve (SUCRA) for each intervention. RESULTS: Our final search on May 15th 2021 retrieved 23,305 unique citations from searching six electronic databases. Eventually, 101 RCTs of 108 reports with a total of 8,765 patients were included in our systematic review and multi-treatments meta-analysis. 55 different interventions were included: 22 monotherapies, and 33 combinations. The two-dimensional cluster ranking of the average SUCRA values for metabolic and hormonal parameters with significant estimates revealed flutamide (77.5%, 70%; respectively) as the highest and rosiglitazone (38.2%, 26.3%; respectively) as the lowest, in terms of the overall efficacy in reducing weight and hyperandrogenism. However, cyproterone-acetate+ethinylestradiol exhibited a higher ranking in improving hormonal parameters (71.1%), but even a lower-ranking regarding metabolic parameters (34.5%). CONCLUSIONS AND RELEVANCE: Current evidence demonstrated the superiority of flutamide in improving both metabolic and hormonal parameters, and the higher efficacy of cyproterone-acetate+ethinylestradiol only in improving hormonal parameters. Nearly all interventions were comparable in female hormones, FGS, HDL, glucose, and insulin levels improvements.

Chinese herbal medicine for subfertile women with polycystic ovarian syndrome.

BACKGROUND: Polycystic ovarian syndrome (PCOS) is characterised by both metabolic and reproductive disorders, and affects 5% to 15% of women of reproductive age. Different western medicines have been proposed for PCOS-related subfertility, such as oral contraceptives, insulin sensitisers and laparoscopic ovarian drilling (LOD). Chinese herbal medicines (CHM) have also been used for subfertility caused by PCOS for decades, and are expected to become an alternative treatment for subfertile women with PCOS. OBJECTIVES: To assess the efficacy and safety of Chinese herbal medicine (CHM) for subfertile women with polycystic ovarian syndrome (PCOS). SEARCH METHODS: We searched the Cochrane Gynaecology and Fertility Group Specialised Register, CENTRAL, MEDLINE, Embase and six other databases, from inception to 2 June 2020. In addition, we searched three trials registries, the reference lists of included trials and contacted experts in the field to locate trials. SELECTION CRITERIA: We included randomised controlled trials (RCTs) comparing CHM versus placebo, no treatment or conventional (western) therapies for the treatment of subfertile women with PCOS. DATA COLLECTION AND ANALYSIS: Two review authors independently screened trials for inclusion, assessed the risk of bias in included studies and extracted data. We contacted primary study authors for additional information. We conducted meta-analyses. We used the odds ratios (ORs) to report dichotomous data, with 95% confidence intervals (CIs). We assessed the certainty of the evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methods. MAIN RESULTS: We included eight RCTs with 609 participants. The comparisons in the included trials were as follows: CHM versus clomiphene, CHM plus clomiphene versus clomiphene (with or without ethinyloestradiol cyproterone acetate (EE/CPA)), CHM plus follicle aspiration plus ovulation induction versus follicle aspiration plus ovulation induction alone, and CHM plus laparoscopic ovarian drilling (LOD) versus LOD alone. The overall certainty of the evidence for most comparisons was very low. None of the included studies reported the primary outcome, live birth rate. Most studies reported the secondary outcomes, and only one study reported data on adverse events. In trials that compared CHM to clomiphene (with or without LOD in both study arms), we are uncertain of the effect of CHM on pregnancy rates (odds ratio (OR) 1.41, 95% confidence interval (CI) 0.63 to 3.19; I2 = 28%; 3 studies, 140 participants; very low certainty evidence). Results suggest that if the chance of pregnancy following clomiphene is assumed to be 21.5%, the chance following CHM would vary between 14.7% and 46.7%. No study reported data on adverse events. When CHM plus clomiphene was compared to clomiphene (with or without EE/CPA), there was low certainty evidence of a higher pregnancy rate in the CHM plus clomiphene group (OR 3.06, 95% CI 2.05 to 4.55; I2 = 10%; 6 studies, 470 participants; low certainty evidence). Results suggest that if the chance of pregnancy following clomiphene is assumed to be 31.5%, the chance following CHM plus clomiphene would vary between 48.5% and 67.7%. No data were reported on adverse events. In trials that compared CHM plus follicle aspiration and ovulation induction to follicle aspiration and ovulation induction alone, we are uncertain of the effect of CHM on pregnancy rates (OR 1.62, 95% CI 0.46 to 5.68; 1 study, 44 women; very low certainty evidence). Results suggest that if the chance of pregnancy following follicle aspiration and ovulation induction is assumed to be 29.2%, the chance following CHM with follicle aspiration and ovulation induction would vary between 15.9% and 70%. Reported adverse events included severe luteinised unruptured follicle syndrome (LUFS) (Peto OR 0.60, 95% CI 0.06 to 6.14; 1 study, 44 women; very low certainty evidence), ovarian hyperstimulation syndrome (OHSS) (Peto OR 0.16, 95% CI 0.00 to 8.19; 1 study, 44 women; very low certainty evidence) or multiple pregnancy (Peto OR 0.60, 95% CI 0.06 to 6.14; 1 study, 44 women; very low certainty evidence). These results suggest that if the chances of LUFS, OHSS, and multiple pregnancy following follicle aspiration and ovulation induction are assumed to be 8.3%, 4.2%, and 8.3% respectively, the chances following CHM with follicle aspiration and ovulation induction would be 0.5% to 35.8%, 0% to 26.3% and 0.5% to 35.8% respectively.  In trials that compared CHM plus LOD to LOD alone, we are uncertain if CHM improves pregnancy rates (OR 3.50, 95% CI 0.72 to 17.09; 1 study, 30 women; very low certainty evidence). Results suggest that if the chance of pregnancy following LOD is assumed to be 40%, the chance following CHM with LOD would vary between 32.4% and 91.9%. No data were reported on adverse events. We are uncertain of the results in the comparison groups for all outcomes. The certainty of the evidence for all other comparisons and outcomes was very low. The main limitations in the evidence were failure to report live birth or adverse events, failure to describe study methods in adequate detail and imprecision due to very low event rates and wide CIs. AUTHORS' CONCLUSIONS: There is insufficient evidence to support the use of CHM for subfertile women with PCOS. No data are available on live birth. We are uncertain of the effect of CHM on pregnancy rates for there is no consistent evidence to indicate that CHM influences fertility outcomes. However, we find that the addition of CHM to clomiphene may improve pregnancy rates, but there is very limited, low certainty evidence for this outcome. Furthermore, there is insufficient evidence on adverse effects to indicate whether CHM is safe. In the future, well-designed, carefully conducted RCTs are needed, with a particular focus on the live birth rate and other safety indexes.

Sustained growth of intraosseous hormone-associated meningiomas after cessation of progestin therapy.

Hormone-associated meningiomas tend to stop growing or decrease in size after cessation of certain progestins, mainly cyproterone acetate. We report three observations on the natural history of hormone-associated intraosseous meningiomas, showing in a first patient that those tumors may grow rapidly under nomegestrol. We then demonstrate the sustained growth of intraosseous hormone-associated meningiomas after cessation of promesgestone and nomegestrol, independently of the intracranial portion, which concurrently decreased in size in the second case or was resected at the time of nomegestrol withdrawal in the third case, thus giving new insights into the tumorigenesis mechanisms of hormone-associated intraosseous meningiomas.

A population K-PD model analysis of long-term testosterone inhibition in prostate cancer patients undergoing intermittent androgen deprivation therapy.

Intermittent androgen deprivation therapy with gonadotropin-releasing-hormone (GnRH) agonists can prevent or delay disease progression and development of castration resistant prostate cancer for subpopulations of prostate cancer patients. It may also reduce risk and severity of side effects associated with chemical castration in prostate cancer (PCa) patients. One of the earliest comprehensively documented clinical trials on this was reported in a Canadian patient population treated with leuprorelin preceded by a lead-in with cyproterone acetate. A systems-based mixed effect analysis of testosterone response in active and recovery phases allows inference of new information from this patient population. Efficacy of androgen deprivation therapy is presumed to depend on a treshold value for testosterone at the nadir, below which no additional beneficial effects on PSA reponse can be expected, and occurance of testosterone breakthroughs during active therapy. The present analysis results in a mixed effect model, incorporating GnRH receptor activation, testosterone turnover and feedback mechanisms, describing and predicting testosterone inhibition under intermittent androgen deprivation therapy on the individual and population level, during multiple years of therapy. Testosterone levels in these patients decline over time with an estimated first order rate constant of 0.083 year-1(T1/2 = 8.4 y), with a substantial distribution among this patient population, compared to the general population. PCa patients leaving the trial due to unmanageble PSA relapse appear to have slightly higher testosterone levels at the nadir than sustained responders. These findings are expected to contribute to an increased understanding of the role of testosterone in long term disease progression of prostate cancer.

Cyproterone acetate and meningioma: a nationwide-wide population based study.

BACKGROUND: The study the characteristics of surgical meningiomas in female patients who took CPA and to compare this population to a non-CPA control group. MATERIALS AND METHODS: We processed the French Système National des Données de Santé (SNDS) database to retrieve appropriate cases operated between 2007 and 2017. RESULTS: 1 101 female patients (3.8%) who used to take CPA and underwent a meningioma surgery were extracted from a nationwide population based cohort of 28 924 patients. Median age at CPA prescription was 42 years IQR[36.7-48.9]. The median time between CPA start and surgery was 5.5 years IQR[3.1-7.9]. The median age at surgery was significantly lower in patients who were treated by CPA (47 years, IQR[42-54) compared to the non-CPA population (61 years, IQR[51-70], p < 0.001). Median CPA dose was 40 g, IQR[19-72]. There was a strong correlation between CPA dose and duration (r = 0.58, 95%CI[0.54-0.62], p < 0.001). Middle skull base was the most common (39%) location with a anterior skull base insertion being also far more common compared to the usual population with 21.9% of the tumour. This skull base predominance of CPA-associated meningioma is highly significant (p < 0.001). Increased CPA dose raised the risk of having multiple meningioma surgeries (p < 0.001) and multiple meningioma locations (p < 0.001). Tumour grading was not modified by CPA treatment (p = 0.603). Benign or grade I meningioma accounting for 92%, atypical or grade II for 6.1% and malignant or grade III for 1.9%. CONCLUSION: In the past 10 years, a significant number of CPA-induced meningiomas have been removed, modifying the global pyramid of age at surgery for female patients. These tumours occur well before the usual age and are preferentially located on the anterior and middle skull base.

A systematic review of antiandrogens and feminization in transgender women.

Antiandrogens are frequently used with estradiol in transgender women seeking feminization. Antiandrogens act by various mechanisms to decrease the production or effects of testosterone, but it is unclear which antiandrogen is most effective at feminization. A systematic review was performed using PRISMA guidelines. We searched online databases (Medline, Embase and PsycINFO) and references of relevant articles for studies of antiandrogens in transgender women aged 16+ years to achieve feminization (namely changes in breast size, body composition, facial or body hair) or changes in serum total testosterone concentration when compared to placebo, estradiol alone or an alternative antiandrogen. Four studies fulfilled eligibility criteria and were included in a narrative review. The addition of cyproterone acetate, leuprolide and medroxyprogesterone acetate may be more effective than spironolactone or estradiol alone at suppressing the serum total testosterone concentration. Body composition changes appear similar in transgender women treated with estradiol and additional cyproterone acetate or leuprolide. No eligible studies adequately evaluated the effects of antiandrogens on breast development or facial and body hair reduction. It remains unclear which antiandrogen is most effective at achieving feminization. Cyproterone acetate, medroxyprogesterone acetate and leuprolide may be more effective than spironolactone at suppressing the serum total testosterone concentration. However, due to spironolactone's antagonism of the androgen receptor, it is unclear whether this results in clinically meaningful differences in feminization. Further research with clinically meaningful endpoints is needed to optimize the use of antiandrogens in transgender women.

Variation in sensitivity and rate of change in body composition: steps toward individualizing transgender care.

OBJECTIVE: Transgender individuals sometimes report a lack of physical change during hormone treatment, such as alterations in muscle tone or fat distribution. Identifying characteristics of this subgroup could be a step toward individualizing hormone therapy in transgender individuals. Therefore, we study the variation of changes in body composition and characteristics associated with a lack of change. DESIGN AND METHODS: Body composition measures were recorded in 323 transmen and 288 transwomen at every visit from the start of hormone therapy to a maximum of 24 months follow-up. Absence of change was defined as transmen with a decrease in lean body mass or transwomen with a decrease in fat percentage. RESULTS: A lack of change at 24 months was observed in 19 of 94 (20.2%) transmen and in 9 of 96 (9.4%) transwomen. The risk of not achieving change in body composition was related to lower testosterone levels and less suppression of LH in transmen (OR: 0.67, 95% CI: 0.48-0.94 per SD increase in testosterone and OR: 1.36, 95% CI: 1.01-1.83 per SD increase in LH). CONCLUSIONS: There is a large variation in body composition changes during hormone therapy, with a substantial proportion of individuals with no measurable effects. In transmen, serum testosterone and LH were associated with a lack of change, but serum hormone levels were not associated with body composition changes in transwomen. The results provide a rationale for individualizing hormone therapy in transmen, by considering individual effects rather than solely relying on a standardized dosage of hormone therapy.

Biomarkers of postmenopausal osteoporosis and interventive mechanism of catgut embedding in acupoints.

INTRODUCTION: Postmenopausal osteoporosis (PMOP), which is a common and frequently occurring age-related metabolic bone disease in perimenopausal women, severely affects patients living quality. Modern medicine therapies for PMOP have several problems such as side reactions, low compliance, and high costs. Thus, nonpharmacological modality is urgently needed. Although acupoint thread embedding treatment is widely used in clinical practice, there is no persuasive evidence of its effect on increasing bone mass for PMOP. This experiment aims to investigate the efficacy and safety of acupoint thread embedding on PMOP and elucidate the correlations among brain neural activation, bone mineral density (BMD), and clinical outcomes with magnetic resonance evidence, thus to explore its neural mechanism. METHODS: This parallel designed, exploratory randomized, controlled, assessor-statistician-blinded, positive medicine clinical trial will include 70 participants with PMOP recruited from 2 traditional Chinese Medicine hospitals. These participants will be randomly allocated to a treatment group (Group Embedding) and a control group (Group Medication) in a 1:1 ratio. Participants in the treatment group will receive acupoint thread embedding treatment once 2 weeks in the following predefined acupoints: Shenshu (BL23), Sanyinjiao (SP6), Guanyuan (RN4), Ganshu (BL18), Dazhu (BL11), Xuanzhong (GB39), Zusanli (ST36), and Pishu (BL20). Meanwhile, the participants in the control group will take 0.3 mg Climen tablet orally, 1 tablet/day; every month has a schedule of the 21-day-continuous-taking-medicine period, and 7-day tablet-free period. There is a study period of 3 months and a follow-up period of 1 month for each group. The primary outcomes will be the following therapeutic indexed: Short-Form of McGill Pain Questionnaire (SF-MPQ), Osteoporosis Symptom Score during the observation period and follow-up period. The secondary outcomes will be Osteoporosis Quality of Life Scale (OQOLS), 16-item Assessment of Health-Related Quality of Life in Osteoporosis. In addition, functional magnetic resonance imaging (fMRI) scans and bone density test will be done before and after the observation period to show cranial neuroimaging changes. All the outcomes will be evaluated before and after treatment. The safety of interventions will be assessed at every visit. DISCUSSION: We present study design and rationale to explore the effectiveness and neural mechanism of acupoint thread embedding for PMOP through these outcomes. TRIAL REGISTRATION: Chinese Clinical Trial Registry, ChiCTR-INR-17011491.

Is There An Advantage of Using Dingkun Pill () alone or in Combination with Diane-35 for Management of Polycystic Ovary Syndrome? A Randomized Controlled Trial.

OBJECTIVE: To evaluate the effects of Chinese medicine Dingkun Pill () alone or in combination with Diane-35 on patients with polycystic ovary syndrome (PCOS). METHODS: This is a prospective randomized controlled trial conducted at Peking Union Medical College Hospital Beijing, China, from December 2016 to September 2017. Totally 117 PCOS patients were randomly assigned to the Dingkun Pill group (38 cases), Diane-35 group (40 cases), or combined group (39 cases). Patients in the Dingkun Pill group or Diane-35 group took daily 7 g of oral Dingkun Pill or 1 tablet of oral Diane-35, respectively, for 21 consecutive days followed by 7 drug-free days. And the combined group received a combination of Dingkun Pill and Diane-35. The treatment course was 3 months. Fasting plasma glucose and insulin, total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), free fatty acids (FFA) and sex hormones were analyzed, quantitative insulin sensitivity check index (QUICKI) was calculated, and menstruation and acne scores were recorded at baseline and after 3-month treatment. RESULTS: Compared with before treatment, QUICKI decreased significantly in the Dingkun Pill and combined groups after 3-month treatment (P<0.05); TC, LDL-C and FFA decreased significantly in the Dingkun Pill group (P<0.01), LDL-C also decreased obviously in the Diane-35 group (P<0.01), while TC increased significantly in the combined group (P<0.01), TG increased significantly in all groups (P<0.01); total testosterone (TT) and menstruation regularity was improved significantly in the Diane-35 and combined groups (P<0.01); acne scores were improved in all groups (P<0.01). After treatment, TC and FFA in the Dingkun Pill group were significantly lower than the Diane-35 group (P<0.05 or P<0.01); TT was lower and regular menstruation rate was higher in the Diane-35 and combined groups than the Dingkun Pill group (P<0.01), and no differences were observed between Diane-35 group and combined group (P>0.05). CONCLUSIONS: Dingkun Pill showed better effects than Diane-35 in improving insulin sensitivity, lowering TC and FFA. Diane-35 was more efficient in regulating menstruation and lowering androgen than Dingkun Pill. Combination of Dingkun Pill and Diane-35 may be a better choice to regulate menstruation, lower androgens while improve glucose metabolism in PCOS patients.
