RESUMO

BACKGROUND: Hypoactive Sexual Desire Disorder (HSDD) is a frequent sex-related problem in women; however, a specific tool to characterize HSDD subtypes based on sexual inhibitory and excitatory factors is still lacking. AIM: (1) To find a cutoff value in Sexual Inhibition Scale (SIS)/Sexual Excitation Scale (SES) scores predicting a diagnosis of HSDD in women consulting for sexual symptoms, (2) to explore the sexual inhibitory and excitatory profiles in women referred to a clinic for female sexual dysfunction by stratifying the sample according to the newfound cutoffs, and (3) to identify biopsychosocial factors significantly associated with the 2 profiles. METHODS: An overall 133 women consulting for sexual symptoms were retrospectively evaluated for clinical, biochemical, and psychosexologic data collected at the first visit. A subgroup of 55 women treated with transdermal testosterone was retrospectively analyzed at baseline and the 6-month visit. OUTCOMES: Patients underwent physical and laboratory examinations and completed the SIS/SES, Female Sexual Function Index, Female Sexual Distress Scale-Revised, Emotional Eating Scale, and Middlesex Hospital Questionnaire. RESULTS: Specific cutoffs for SIS1 (≥32.5; indicating threat of performance failure) and SES (≤46.5) predicted HSDD diagnosis with an accuracy of 66.4% (P = .002) and 68.7% (P < .0001), respectively. Patients with impaired SIS1 scores showed higher distress and psychopathologic symptoms, while those with impaired SES scores demonstrated lower desire and arousal and a negative association with some metabolic and hormonal parameters. SES score also showed a significant predictive value on testosterone treatment efficacy for HSDD. CLINICAL TRANSLATION: A better characterization of HSDD would enable individualized treatment based on the main underlying etiologies. STRENGTHS AND LIMITATIONS: Limitations of the study include the small sample size and cross-sectional retrospective design, with the choice of treatment for HSDD limited to transdermal testosterone. Strengths comprise the thorough and multifactorial evaluation of every aspect potentially affecting inhibitory and excitatory components of sexual desire. CONCLUSION: Validated cutoffs of SIS/SES scores could allow deep characterization of women diagnosed with HSDD, thus ensuring better tailoring of therapy and prediction of the probability of response to specific treatments.

RESUMO

The substantial increase in life expectancy of men has focused growing attention on quality-of-life issues associated with reproductive aging. Serum total and free testosterone levels in men, after reaching a peak in the second and third decade of life, decline gradually with advancing age. The trajectory of age-related decline is affected by comorbid conditions, adiposity, medications, and genetic factors. Testosterone treatment of older men with low testosterone levels improves overall sexual activity, sexual desire, and erectile function; improves areal and volumetric bone density, as well as estimated bone strength in the spine and the hip; corrects unexplained anemia of aging; increases skeletal muscle mass, strength and power, self-reported mobility, and some measures of physical function; and modestly improves depressive symptoms. The long-term effects of testosterone on major cardiovascular events and prostate cancer risk remain unclear. The Endocrine Society recommends against testosterone therapy of all older men with low testosterone levels but suggests consideration of treatment on an individualized basis in men who have consistently low testosterone levels and symptoms or conditions suggestive of testosterone deficiency.

RESUMO

STUDY QUESTION: Can spindle transfer (ST) overcome inferior embryonic development of in vitro matured ovarian tissue oocytes (OTO-IVM) originating from testosterone-treated transgender men? SUMMARY ANSWER: ST shows some potential to overcome the embryo developmental arrest observed in OTO-IVM oocytes from transgender men. WHAT IS KNOWN ALREADY: OTO-IVM is being applied as a complementary approach to increase the number of oocytes/embryos available for fertility preservation during ovarian tissue cryopreservation in cancer patients. OTO-IVM has also been proposed for transgender men, although the potential of their oocytes remains poorly investigated. Currently, only one study has examined the ability of OTO-IVM oocytes originating from transgender men to support embryo development, and that study has shown that they exhibit poor potential. STUDY DESIGN, SIZE, DURATION: Both ovaries from 18 transgender men undergoing oophorectomy were collected for the purposes of this study, from November 2020 to September 2022. The patients did not wish to cryopreserve their tissue for fertility preservation and donated their ovaries for research. All patients were having testosterone treatment at the time of oophorectomy and some of them were also having menses inhibition treatment. PARTICIPANTS/MATERIALS, SETTING, METHODS: Sibling ovaries were collected in either cold or warm medium, to identify the most optimal collection temperature. Cumulus oocyte complexes (COCs) from each condition were isolated from the ovarian tissue and matured in vitro for 48 h. The quality of OTO-IVM oocytes was assessed by calcium pattern releasing ability, embryo developmental competence following ICSI, and staining for mitochondrial membrane potential. In vitro matured metaphase I (MI) oocytes, germinal vesicle (GV) oocytes, and in vivo matured oocytes with aggregates of smooth endoplasmic reticulum (SERa) were donated from ovarian stimulated women undergoing infertility treatment and these served as Control oocytes for the study groups. ST was applied to overcome poor oocyte quality. Specifically, enucleated mature Control oocytes served as cytoplasmic recipients of the OTO-IVM spindles from the transgender men. Embryos derived from the different groups were scored and analysed by shallow whole genome sequencing for copy number variations (CNVs). MAIN RESULTS AND THE ROLE OF CHANCE: In total, 331 COCs were collected in the cold condition (OTO-Cold) and 282 were collected in the warm condition (OTO-Warm) from transgender men. The maturation rate was close to 54% for OTO-Cold and 57% for OTO-Warm oocytes. Control oocytes showed a calcium releasing ability of 2.30 AU (n = 39), significantly higher than OTO-Cold (1.47 AU, P = 0.046) oocytes (n = 33) and OTO-Warm (1.03 AU, P = 0.036) oocytes (n = 31); both values of calcium release were similar between the two collection temperatures. Mitochondrial membrane potential did not reveal major differences between Control, OTO-Warm, and OTO-Cold oocytes (P = 0.417). Following ICSI, 59/70 (84.2%) of Control oocytes were fertilized, which was significantly higher compared to 19/47 (40.4%) of OTO-Cold (P < 0.01) and 24/48 (50%) of OTO-Warm oocytes (P < 0.01). In total, 15/59 (25.4%) blastocysts were formed on Day 5 in the Control group, significantly higher than 0/19 (0%) from the OTO-Cold (P = 0.014) and 1/24 (4.1%) in OTO-Warm oocytes (P = 0.026). Application of ST rescued the poor embryo development, by increasing the Day 5 blastocyst rate from 0% (0/19) to 20.6% (6/29) (P = 0.034), similar to that in the ICSI-Control group (25.4%, 15/59). A normal genetic profile was observed in 72.7% (8/11) of OTO-Cold, 72.7% (8/11) of OTO-Warm and 64.7% (11/17) of Control Day 3-Day 5 embryos. After ST was applied for OTO-IVM oocytes, 41.1% (7/17) of the embryos displayed normal genetic patterns, compared to 57.1% (4/7) among ST-Control Day 3-Day 5 embryos. LARGE SCALE DATA: N/A. LIMITATIONS, REASONS FOR CAUTION: Due to the limited access to human oocytes and ovarian tissue, our results should be interpreted with some caution, as only a limited number of human oocytes and embryos could be investigated. WIDER IMPLICATIONS OF THE FINDINGS: The results of this study, clearly indicate that OTO-IVM oocytes originating from transgender patients are of inferior quality, which questions their use for fertility preservation. The poor quality is likely to be related to cytoplasmic factors, supported by the increased blastocyst numbers following application of ST. Future research on OTO-IVM from transgender men should focus on the cytoplasmic content of oocytes or supplementation of media with factors that promote cytoplasmic maturation. A more detailed study on the effect of the length of testosterone treatment is also currently missing for more concrete guidelines and guidance on the fertility options of transgender men. Furthermore, our study suggests a potentially beneficial role of experimental ST in overcoming poor embryo development related to cytoplasmic quality.

RESUMO

Functional hypogonadism is a condition characterized by low testosterone concentrations, occurring more commonly in men as they age. The International Prostate Symptom Score (IPSS) is used to categorize the severity of lower urinary tract symptoms (LUTS) and related symptoms in hypogonadal men. Testosterone therapy (TTh) has previously shown potential in improving total IPSS in men with hypogonadism. However, concerns regarding the effects of urinary function following TTh often prevent treatment in hypogonadal men. To explore this further, two population-based single-center, prospective, cumulative registry studies were combined to contribute to a total population of 1176 men with symptoms of hypogonadism. The total population was separated into a TTh group receiving testosterone undecanoate (TU) for up to 12 years and a control group that did not receive treatment. IPSS was recorded at both baseline and at final recorded visit for each patient. Long-term TTh with TU in hypogonadal men resulted in significant improvements in IPSS categories, even in patients with severe symptoms at baseline. In the control group, untreated hypogonadal men experienced a worsening of IPSS categories. These data indicate that TTh improves LUTS in men with hypogonadism and suggest that previous concerns regarding urinary function may have been overstated.

RESUMO

The negative cardiovascular effects of polycystic ovary syndrome (PCOS) and vitamin D deficiency (VDD) have been discussed previously; however, the sex differences between PCOS females and males are not yet known. Our aim was to investigate the effect of PCOS and VDD in the carotid artery of male and female Wistar rats. Females were treated with transdermal testosterone (Androgel) for 8 weeks, which caused PCOS. VDD and vitamin D supplementation were accomplished via diet. The carotid arteries' contraction and relaxation were examined using myography. Receptor density was investigated using immunohistochemistry. In PCOS females, angiotensin receptor density, angiotensin II-induced contraction, androgen receptor optical density, and testosterone-induced relaxation increased. The increased contractile response may increase cardiovascular vulnerability in women with PCOS. As an effect of VDD, estrogen receptor density increased in all our groups, which probably compensated for the reduced relaxation caused by VDD. Testosterone-induced relaxation was decreased as a result of VDD in males and non-PCOS females, whereas this reduction was absent in PCOS females. Male sex is associated with increased contraction ability compared with non-PCOS and PCOS females. VDD and Androgel treatment show significant gender differences in their effects on carotid artery reactivity. Both VDD and PCOS result in a dysfunctional vascular response, which can contribute to cardiovascular diseases.

RESUMO

Twenty men with spinal cord injury (SCI) were randomized into two 16-week intervention groups receiving testosterone treatment (TT) or TT combined with resistance training (TT + RT). TT + RT appears to hold the potential to reverse or slow down bone loss following SCI if provided over a longer period. INTRODUCTION: Persons with SCI experience bone loss below the level of injury. The combined effects of resistance training and TT on bone quality following SCI remain unknown. METHODS: Men with SCI were randomized into 16-week treatments receiving TT or TT + RT. Magnetic resonance imaging (MRI) of the right lower extremity before participation and post-intervention was used to visualize the proximal, middle, and distal femoral shaft, the quadriceps tendon, and the intermuscular fascia of the quadriceps. For the TT + RT group, MRI microarchitecture techniques were utilized to elucidate trabecular changes around the knee. Individual mixed models were used to estimate effect sizes. RESULTS: Twenty participants completed the pilot trial. A small effect for yellow marrow in the distal femur was indicated as increases following TT and decreases following TT + RT were observed. Another small effect was observed as the TT + RT group displayed greater increases in intermuscular fascia length than the TT arm. Distal femur trabecular changes for the TT + RT group were generally small in effect (decreased trabecular thickness variability, spacing, and spacing variability; increased network area). Medium effects were generally observed in the proximal tibia (increased plate width, trabecular thickness, and network area; decreased trabecular spacing and spacing variability). CONCLUSIONS: This pilot suggests longer TT + RT interventions may be a viable rehabilitation technique to combat bone loss following SCI.

RESUMO

The trabecular bone score (TBS) is an indirect measure of vertebral bone microarchitecture. Our objective was to examine the effect of testosterone treatment on TBS. One hundred and ninety-seven hypogonadal men were randomized to testosterone or placebo. After 12 months, there was no difference in the changes in TBS by randomized group. INTRODUCTION: In the Bone Trial of the Testosterone Trials, testosterone treatment increased trabecular volumetric bone mineral density (vBMD) and increased estimated bone strength as determined by finite element analysis. The trabecular bone score (TBS) is an indirect measure of vertebral bone microarchitecture. TBS predicts fracture independent of lumbar spine areal (a) BMD. The objective of this study was to examine the effect of testosterone treatment on TBS compared to its effects on vBMD and aBMD. METHODS: Two hundred and eleven men were enrolled in the Bone Trial of the Testosterone Trials. Of these, 197 men had 2 repeat TBS and vBMD measurements; 105 men were allocated to receive testosterone, and 92 men to placebo for 1 year. TBS, aBMD, and vBMD were assessed at baseline and month 12. RESULTS: There was no difference in the percent change in TBS by randomized group: 1.6% (95% confidence intervals (CI) 0.2-3.9) in the testosterone group and 1.4% (95% CI -0.2, 3.1) in the placebo group. In contrast, vBMD increased by 6% (95% CI 4.5-7.5) in the testosterone group compared to 0.4% (95% CI -1.65-0.88) in the placebo groups. CONCLUSIONS: TBS is not clinically useful in monitoring the 1-year effect of testosterone treatment on bone structure in older hypogonadal men.

RESUMO

The aim was to define the true incidence of gynaecomastia in adolescent boys with Klinefelter syndrome (KS) and to observe testosterone treatment effects on its duration by examination of the prospectively collected data from a specialist referral clinic for boys with KS, with comparison being made with KS boys identified by a historical newborn chromosome screening programme, together with chromosomally normal controls. Fifty-nine boys over age 13 years were referred to a specialist KS clinic; 21 developed gynaecomastia. The comparator was 14 KS boys identified at birth and 94 chromosomally normal control boys. Testosterone was routinely started at the onset of puberty if gynaecomastia, a manifestation of clinical hypogonadism, was present. Oral or transdermal testosterone was administered in the morning, in a reverse physiological rhythm, and doses were increased according to standard pubertal regimens. The incidence of gynaecomastia was not increased in both the KS cohorts compared with controls. The incidence and age of onset of gynaecomastia was 35.6%, at 12.3 (1.8) years in the KS clinic group; 36.0%, at 13.7 (0.6) years in the newborn survey group; and 34.0%, at 13.6 (0.8) years in the controls. Full resolution of the gynaecomastia occurred in the 12/14 KS clinic boys on testosterone treatment who had completed puberty and as long as adherence was maintained.Conclusion: The incidence of gynaecomastia in KS boys (overall 35.6%) is not increased over typically developing boys. Commencing testosterone when gynaecomastia develops with physiological dose escalation and full adherence can result in the resolution of the gynaecomastia. What is Known: • Gynaecomastia is a common feature in Klinefelter syndrome men. • Hypogonadism occurs from mid-puberty onwards with the absence of the usual rise in testosterone levels. What is New: • The incidence of pubertal gynaecomastia in Klinefelter syndrome is not different from typically developing boys. • Early and prompt starting of testosterone gel treatment and increasing the dose physiologically may help to resolve the gynaecomastia without the need for surgery.

RESUMO

OBJECTIVE: This narrative review offers a guideline-based approach for optimizing diagnostic evaluation and treatment decision making in men being evaluated for testosterone deficiency. METHODS: A narrative review. RESULTS: Testosterone deficiency is a clinical syndrome that results from the inability of the testes to produce normal amounts of testosterone and is characterized by a constellation of symptoms and signs associated with consistently low testosterone concentrations. The diagnosis of testosterone deficiency is made by the ascertainment of symptoms and signs; the measurement of total and, if indicated, free testosterone levels in early-morning fasting samples on ≥2 days; the measurement of luteinizing hormone and follicular-stimulating hormone levels to distinguish primary from secondary hypogonadism; and an additional evaluation to ascertain the cause of testosterone deficiency. Nonspecificity of symptoms and signs, variations in testosterone levels over time, inaccuracy in the measurement of total and free testosterone levels, variations in binding protein concentrations, and suboptimal reference ranges contribute to diagnostic inaccuracy. Testosterone treatment is indicated for men with symptomatic testosterone deficiency. Testosterone treatment should be avoided in men with prostate or breast cancer, erythrocytosis, thrombophilia, increased risk of prostate cancer or severe lower urinary tract symptoms without prior urologic evaluation, a recent major adverse cardiovascular event, uncontrolled heart failure, or severe untreated sleep apnea. Testosterone replacement therapy should be accompanied by a standardized monitoring plan. CONCLUSION: A shared decision of the patient and physician to treat should be guided by the consideration of the burden of symptoms, potential benefits and risks, patient's values, and the cost and burden of long-term treatment and monitoring.

RESUMO

PURPOSE: To explore the effects of 6-month systemic testosterone (T) administration on clitoral color Doppler ultrasound (CDU) parameters in women with female sexual dysfunction (FSD). METHODS: 81 women with FSD were retrospectively recruited. Data on CDU parameters at baseline and after 6 months with four different treatments were available and thus further longitudinally analyzed: local non-hormonal moisturizers (NH group), n = 37; transdermal 2% T gel 300 mcg/day (T group), n = 23; local estrogens (E group), n = 12; combined therapy (T + E group), n = 9. Patients underwent physical, laboratory, and genital CDU examinations at both visits and completed different validated questionnaires, including the Female Sexual Function Index (FSFI). RESULTS: At 6-month visit, T therapy significantly increased clitoral artery peak systolic velocity (PSV) when compared to both NH (p < 0.0001) and E (p < 0.0001) groups. A similar increase was found in the T + E group (p = 0.039 vs. E). In addition, T treatment was associated with significantly higher FSFI desire, pain, arousal, lubrication, orgasm, and total scores at 6-month visit vs. baseline. Similar findings were observed in the T + E group. No significant differences in the variations of total and high-density lipoprotein-cholesterol, triglycerides, fasting glycemia, insulin and glycated hemoglobin levels were found among the four groups. No adverse events were observed. CONCLUSION: In women complaining for FSD, systemic T administration, either alone or combined with local estrogens, was associated with a positive effect on clitoral blood flow and a clinical improvement in sexual function, showing a good safety profile.

RESUMO

Metabolic syndrome (MetS) is known to be associated to inflammation and alteration in the hypothalamus, a brain region implicated in the control of several physiological functions, including energy homeostasis and reproduction. Previous studies demonstrated the beneficial effects of testosterone treatment (TTh) in counteracting some MetS symptoms in both animal models and clinical studies. This study investigated the effect of TTh (30 mg/kg/week for 12 weeks) on the hypothalamus in a high-fat diet (HFD)-induced animal model of MetS, utilizing quantitative RT-PCR and immunohistochemical analyses. The animal model recapitulates the human MetS features, including low testosterone/gonadotropin plasma levels. TTh significantly improved MetS-induced hypertension, visceral adipose tissue accumulation, and glucose homeostasis derangements. Within hypothalamus, TTh significantly counteracted HFD-induced inflammation, as detected in terms of expression of inflammatory markers and microglial activation. Moreover, TTh remarkably reverted the HFD-associated alterations in the expression of important regulators of energy status and reproduction, such as the melanocortin and the GnRH-controlling network. Our results suggest that TTh may exert neuroprotective effects on the HFD-related hypothalamic alterations, with positive outcomes on the circuits implicated in the control of energy metabolism and reproductive tasks, thus supporting a possible role of TTh in the clinical management of MetS.

RESUMO

We examined the vasoactive effect of estradiol in a rat model of early PCOS and the influence of vitamin D deficiency (VDD). We created a model of chronic hyperandrogenism and VDD in adolescent female Wistar rats (N = 46) with four experimental groups: vitamin D supplemented (T-D+), VDD (T-D-), hyperandrogenic and vitamin D supplemented (T+D+), and hyperandrogenic and VDD (T+D-). T+ groups received an 8-week-long transdermal Androgel treatment, D-animals were on vitamin D-reduced diet and D+ rats were supplemented orally with vitamin D3. Estrogen-induced vasorelaxation of thoracic aorta segments were measured with a wire myograph system with or without the inhibition of endothelial nitric oxide synthase (eNOS) or cyclooxygenase-2 (COX-2). The distribution of estrogen receptor (ER), eNOS and COX-2 in the aortic wall was assessed by immunohistochemistry. VDD aortas showed significantly lower estradiol-induced relaxation independently of androgenic status that was further decreased by COX-2 inhibition. COX-2 inhibition failed to alter vessel function in D+ rats. Inhibition of eNOS abolished the estradiol-induced relaxation in all groups. Changes in vascular function in VDD were accompanied by significantly decreased ER and eNOS staining. Short-term chronic hyperandrogenism failed to, but VDD induced vascular dysfunction, compromised estrogen-dependent vasodilatation and changes in ER and eNOS immunostaining.

RESUMO

Klinefelter syndrome (KS; 47,XXY) is the most common sex chromosome abnormality in males (150 per 100,000 males). The condition leads to hypergonadotropic hypogonadism and ever since the condition was described approximately 80 years ago, testosterone treatment has been the cornerstone in care for individuals with KS. However, KS is associated with an array of health-related and socioeconomic challenges and it is becoming progressively clear that proper care for boys and men with KS reaches far beyond simply supplementing with testosterone. There are no widely implemented guidelines for KS care, and studies investigating crucial aspects of testosterone treatment in individuals with KS, including both beneficial and potentially adverse effects, have only begun to emerge during the last decades. For this descriptive review, we present an overview of literature describing health-related outcomes of testosterone treatment in KS and outline the clinical applications of testosterone treatment in KS. Collectively, beneficial effects of testosterone treatment on overall health in KS are described with few apparent adverse effects. However, larger randomized studies in adult and pediatric patients are warranted to elucidate key aspects of treatment. We stress the implementation of centralized multidisciplinary clinics and the need for a dedicated international guideline to ensure optimal care of boys and men with KS.

RESUMO

In this commentary, we highlight important findings from a notable RCT by Ng Tang Fui et al. 2016 which investigated the effects of testosterone treatment in dieting obese men. First, a myopic focus on weight loss can detract from important improvements in body composition. Second, while weight loss in obese men may increase testosterone levels, this increase is commonly not enough to result in an improvement in symptoms associated with testosterone deficiency. Third, the RCT by Ng Tang Fui et al. adds evidence to the growing number of clinical trials showing that testosterone therapy should not be restricted to men with classical hypogonadism. Finally, the beneficial effects of testosterone therapy are not maintained after cessation of treatment. Currently, the British Society for Sexual Medicine guidelines are the only clinical guidelines which acknowledge that weight loss per se does not automatically translate to resolution of hypogonadal symptoms, that testosterone therapy can greatly benefit men with testosterone deficiency who do not have classical hypogonadism, and that cessation of testosterone therapy causes reappearance of symptoms and reversal of benefits. Lifelong testosterone therapy is therefore recommended for persistent health benefits in most men with testosterone deficiency. Physicians and patients need to be informed of this.

RESUMO

BACKGROUND: A recent study of older men participating in the Testosterone Trials (TTrials) defined a clinically meaningful change in the Psychosexual Daily Questionnaire (PDQ) question 4 in hypogonadal men age ≥65 years. This study defines clinically meaningful change in the same population for sexual desire assessed by PDQ question 1. AIM: To determine a clinically meaningful change in the answers to question 1 of the PDQ in hypogonadal older men. METHODS: Participants in the Sexual Function Trial of the TTrials were randomly divided into a training and test set. Anchor-based methods, including regression analysis, receiver operating characteristic curves, and empirical cumulative distribution functions, were used to determine a clinically meaningful change on question 1 in the training set, and the selected threshold was evaluated in the test set for an effect of testosterone treatment. RESULTS: A clinically meaningful increase in question 1 of the PDQ was determined to be ≥0.7 points. CLINICAL IMPLICATIONS: Question 1 of the PDQ can be used to assess sexual desire in response to testosterone treatment. STRENGTHS & LIMITATIONS: Data were obtained from a single large study of older hypogonadal men. CONCLUSION: Clinically meaningful improvement of sexual desire is a change of ≥0.7 in the score of question 1 of the PDQ. Stephens-Shields AJ, Wang C, Preston P, et al.

RESUMO

OBJECTIVES: To describe and investigate the hormone treatments in individuals with different forms of disorders of sex development (DSD) and the patients' own views on their treatment. DESIGN: Multicentre cross-sectional clinical evaluation, dsd-LIFE in 6 European countries from February 2014 to September 2015. PARTICIPANTS: A total of 1040 adolescents and adults (≥16 years) with different DSD conditions. MAIN OUTCOMES MEASURES: Hormone replacement, information received and patient satisfaction. RESULTS: Included were women with Turner syndrome (301), 46,XX GD (n = 20), and women with 45,X/46XY (n = 24). Individuals with Klinefelter syndrome (n = 218), 46,XX males (n = 6), individuals with different forms of 46,XY DSD (n = 243): 46,XY DSD conditions (n = 222), men with 45,X/46XY (n = 21) 46,XX CAH, (n = 226). Oestrogen ± progestin was used by 306 (81%) individuals, 72 (19%) received ethinylestradiol and 198 had testosterone treatment. The overall adherence was good, with 10% of women with oestrogen and 5% of those on testosterone had stopped the medication despite 20% reporting dissatisfaction with the treatment, mostly because of psychological side effects. Glucocorticoid replacement in patients with CAH was very seldom stopped. More than 75% were satisfied with the information about the treatment, but the satisfaction with information about treatment options and side effects was lower. CONCLUSIONS: More than 50% in the total cohort had hormone replacement. Although adherence was generally good, this study shows that hormone replacement therapy may be improved. This may be achieved by better individualization of the treatment and by providing specific information to patients regarding both long-term and short-term hormonal effects and side effects.

RESUMO

BACKGROUND: The acquisition of phenotypic male features in transmen with gender dysphoria requires testosterone treatment. The suppression of menses is 1 of the most desired effects. The relation between testosterone levels and human aggressive behavior has been described. However, the effects of testosterone on anger expression have been poorly investigated in trans-persons. AIM: To assess the effects of testosterone treatment on anger expression in transmen using a validated self-report questionnaire (Spielberger's State-Trait Anger Expression Inventory-2 [STAXI-2]). METHODS: 52 transmen diagnosed with gender dysphoria were evaluated before (T0) and at least 7 months after (T1) initiation of continuous gender-affirming testosterone treatment. Sociodemographic characteristics, anthropometric parameters, diagnosis of psychiatric disorders, current psychopharmacologic treatments, and life events were investigated at T0. OUTCOMES: STAXI-2 scores, serum testosterone, and estradiol levels at T0 and T1 were compared. RESULTS: Most of the sample (61.5%, n = 32) had no Axis I or II comorbidity. All subjects at T1 achieved significantly higher serum testosterone levels (5.67 ± 3.88 ng/mL), whereas no significant difference in estradiol levels was observed from T0 to T1. At T1 only 46.2% (n = 24) of the sample achieved iatrogenic amenorrhea, whereas most of the sample had persistent regular bleedings. A significant increase in STAXI anger expression and anger control scores from T0 to T1 was recorded. Patients with persistent bleedings and Axis I disorders seemed to have higher odds of expressing anger. However, circulating testosterone levels at T1 did not influence anger expression. CLINICAL IMPLICATIONS: Interestingly, despite the increase of anger expression scores, during continuous testosterone treatment, there were no reports of aggressive behavior, self-harm, or psychiatric hospitalization. STRENGTHS AND LIMITATIONS: A limitation to this study is that although the STAXI-2 is a well-validated instrument measuring anger expression, it is a self-report psychometric measure. CONCLUSION: This study demonstrates that during 7 months of continuous gender-affirming hormonal treatment, anger expression and anger arousal control increased in transmen. Persistence of menstrual bleedings and Axis I disorders, but not circulating testosterone levels, were predictive of the increase in anger expression score. Continuous psychological support to transmen during gender-affirming hormonal treatment was useful to prevent angry behaviors and decrease the level of dysphoria.

RESUMO

BACKGROUND: Limited information is available on the performance characteristics of 2 questionnaires commonly used in clinical research, the Psychosexual Daily Questionnaire (PDQ) and the Derogatis Interview for Sexual Function (DISF)-II Assessment, especially in older men with low testosterone (T) and impaired sexual function. AIM: To determine reliability of PDQ and DISF-II by assessing the correlation within and between domains in the questionnaires and to define clinically meaningful changes in sexual activity (PDQ question 4 [Q4]) and desire (DISF-II sexual desire domain [SDD]) domains. METHODS: Data from 470 men participating in the T Trials were used to calculate Spearman correlation coefficients of individual items and total score among questionnaires to determine convergent and construct validity. Clinically meaningful changes for sexual desire and activity were determined by randomly dividing the sample into training and validation sets. Anchor- and distribution-based clinically meaningful change criteria were defined in the training set, and selected changes were evaluated in the validation set. OUTCOMES: Validity of the PDQ and DISF-II and clinically meaningful changes in sexual desire and activity were determined in older men in T Trials. RESULTS: Moderate to strong correlations were shown within and between domains from different questionnaires. Using Patient Global Impression of Change as an anchor, clinically meaningful change in PDQ sexual activity was ≥0.6, and in DISF-SDD was ≥5.0. Applying these change cut-points to the validation set, a greater proportion of T-treated men achieved clinically meaningful improvement in their sexual desire and activity compared to placebo-treated men. CLINICAL IMPLICATIONS: The PDQ-Q4 and DISF-II-SDD can be used to reliably assess clinically meaningful changes in sexual activity and sexual desire in hypogonadal men treated with T. STRENGTHS & LIMITATIONS: Strengths of this study include a large sample size, long trial duration, and inclusion of men with low libido and unequivocally low T levels. Limitations include using data from a single study that enrolled only older hypogonadal men, and only 1 anchor for both sexual desire and activity. CONCLUSION: Moderate to strong correlations were demonstrated within and between different sexual domains of the PDQ and DISF-II confirming construct and convergent validity. Clinically meaningful improvement in elderly hypogonadal men was change of ≥0.6 score in the PDQ-Q4 and ≥5.0 in the DISF-SDD. Improvements in sexual activity and desire in the T Trials were modest but clinically meaningful. Wang C, Stephens-Shields AJ, DeRogatis LR, et al.

RESUMO

Sex hormones and the serotonergic system interact in the regulation of mood, learning, memory and sexual behaviour. However, the mechanisms have not been fully explored. The serotonin transporter protein (5-HTT) regulates synaptic concentrations of serotonin and is a primary target for selective serotonin reuptake inhibitors. The aim of this study was to explore how estrogen treatment alone or in combination with testosterone affects 5-HTT binding potentials measured by positron emission tomography (PET) in specific brain regions of postmenopausal women. Ten healthy surgically postmenopausal women (years since oophorectomy 7.5 ± 4.0, mean ± SD) underwent PET examinations at baseline, after three months of estrogen treatment (transdermal estradiol 100 µg/24 hours) and after another three months of combined estrogen and testosterone (testosterone undecanoate 40 mg daily) treatment using the radioligand [(11)C] MADAM developed for examination of the serotonin transporter. The 5-HTT binding potentials decreased significantly in several cortical regions, as well as in limbic and striatal regions after both estrogen treatment alone and combined estrogen/testosterone treatment in comparison to baseline. The observed decrease in 5-HTT could either be due to direct effects on serotonin transporter expression or be the result of indirect adaptation to estrogen and /or testosterone effects on synaptic serotonin levels. Although the mechanism still needs further exploration, the study supports the view that gonadal hormones play a role in serotonin regulated mood disorders.
