[Resveratrol enhances the local antioxidant ability of the ovary in rats with polycystic ovary syndrome].

OBJECTIVE: To investigate the effects of resveratrol (RSV) on ovarian morphology, plasma anti-Müllerian hormone (AMH) and insulin-like growth factor 1 levels (IGF-1), and oxidative stress parameters in rats with polycystic ovary syndrome (PCOS). METHODS: Forty-six rats were randomly divided into a normal control (n = 12), a PCOS model control (n = 12), a rosiglitazone (RSG, n = 11), and an RSV group (n = 11). The PCOS model was established in the latter three groups by rejection of epidehydroandrosterone. The rats in the normal control and PCOS model control groups were treated by gavage of normal saline and those in the RSG and RSV groups by intragastric administration of RSG at 10 mg/(kg·d) and RSV at 3.0 mg/(kg·d), respectively. After 4 weeks of treatment, the ovarian histology was observed under the light microscope, the levels of plasma AMH and IGF-1 measured by ELISA, and the activities of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and catalase (CAT) in the ovarian tissue detected using the Ellman, Sun and AEBI methods, respectively. RESULTS: After a 4-week treatment, statistically significant differences were observed in the above indicators between the normal control and PCOS model control groups (P<0.05). The rats treated with RSG and RSV also showed significant differences in these parameters from the model controls (P<0.05). CONCLUSION: RSV can enhance the local antioxidant capacity of the ovary, reduce the levels of AMH and IGF-1, and improve the morphology of the ovarian tissue in rats with PCOS, indicating its potential value in the treatment of PCOS.

Exploring the efficacy and safety of acupuncture versus sham acupuncture for diminished ovarian reserve: study protocol for a multicentre randomised controlled trial.

INTRODUCTION: The therapeutic needs of women with diminished ovarian reserve (DOR), coupled with the increasing application of acupuncture in improving ovarian function, have highlighted the need to verify the efficacy and safety of acupuncture for DOR. This study aims to provide high-quality evidence by evaluating both ovarian reserve and in vitro fertilisation (IVF) outcomes. METHODS AND ANALYSIS: A large-scale, multicentre, randomised controlled trial will be carried out across seven hospitals in China. 400 women with DOR will be randomised in a 1:1 ratio to an acupuncture group or a sham acupuncture group. Acupuncture or sham acupuncture will consist of 36 sessions per participant over 12 weeks. The primary outcome will be the change in antral follicle count (AFC) at week 12 from baseline. Secondary outcomes are AFC at week 24, the serum levels of basal follicle-stimulating hormone and anti-Mullerian hormone at weeks 12 and 24, the scores of the Self-Rating Anxiety Scale at weeks 12 and 24, clinical pregnancy rate, and IVF embryo transfer related outcomes. Any adverse events during treatment will be documented. ETHICS AND DISSEMINATION: The study protocol has been approved by all the participating institutions. Written informed consent will be obtained prior to participant enrolment. The results of this study will be published in peer-reviewed publications. TRIAL REGISTRATION NUMBER: ChiCTR2200062295 PROTOCOL VERSION: V2.0-20220317.

Anti-Müllerian hormone and fertility in women after childhood cancer treatment: Association with current infertility risk classifications.

BACKGROUND: To identify childhood cancer survivors (CCSs) at risk of premature ovarian insufficiency (POI) and impaired fertility is important given its impact on quality of life. The aim of this study was to assess ovarian markers and fertility outcomes in adult female CCSs. We used the Swedish and the PanCareLIFE classifications for infertility risk grouping. METHODS: 167 CCSs, at median age 34.6 years (19.3-57.8) with a median follow-up time of 25.4 years (11.6-41.3), and 164 healthy matched controls were included in this cross-sectional study. We assessed anti-Müllerian hormone (AMH) levels, antral follicle count (AFC), ovarian volume (OV), and fertility outcomes. Based on gonadotoxic treatments given, CCSs were categorized into infertility risk groups. RESULTS: The median levels of AMH, AFC and OV were lower in CCSs (1.9 vs. 2.1 ng/ml, 12.0 vs. 13.0, 6.8 vs. 8.0 cm3) compared with controls, although statistically significant only for OV (p = 0.021). AMH levels in CCSs <40 years were lower for those classified as high-risk (p = 0.034) and very high-risk (p<0.001) for infertility, based on the Swedish risk classification. Similarly, AFC was reduced in the high-risk (p<0.001) and the very high-risk groups (p = 0.003). CCSs of all ages showed a trend towards impaired fertility, especially in the very high-risk group. POI was diagnosed in 22/167 CCSs, of whom 14 were in the high- and very high-risk groups. The results according to the PanCareLIFE classification were similar. CONCLUSION: Both the Swedish and the PanCareLIFE infertility risk classifications are reliable tools for identifying those at risk of reduced ovarian markers and fertility, as well as POI. We recommend fertility preservation counselling for patients receiving highly gonadotoxic treatments (i.e., Cyclophosphamide Equivalent Dose ≥6 g/m2, radiotherapy exposure to ovaries or stem cell transplantation) with follow-up at a young reproductive age due to the risk of a shortened reproductive window.

Anti-Müllerian hormone as a promising novel biomarker for litter size in Romanov sheep.

Anti-Müllerian hormone (AMH) is a hormone produced by growing preantral and antral follicles of the ovary. AMH is accepted as an important biomarker for fertility and superovulation parameters in livestock species. This study aimed to evaluate changes in serum AMH level in the oestrous cycle, repeatability of AMH, the effect of age on serum AMH level and the effects of AMH on litter size in Romanov sheep. In the study, a total of 36 Romanov sheep were used as animal material. First blood samples (0th day) were collected from 36 ewes to evaluate AMH and progesterone levels. Second blood samples were collected randomly from 20 ewes 9 days after first sampling to compare AMH levels at two different periods of the oestrous cycle in Romanov ewes. The ewes were categorized into three groups as low, medium and high AMH based on their first AMH levels. Results indicated that serum AMH level did not change during the oestrous and dioestrous phases of the oestrous cycle and two random time points of the oestrous cycle (p > .05). Pearson correlation analysis revealed that there is a high (r = .95) and significant (p < .001) correlation between AMH levels at the 0th (AMH-1) and 9th (AMH-2) days. The effect of AMH level on litter size was found to be significant. Litter size was significantly higher in the high AMH group than in the low AMH group (p < .05). In addition, the age of ewes did not affect serum AMH levels (p > .05). ROC analysis indicates that AMH cut-off value >320 pg/mL with 70% sensitivity and 100% specificity can be used for litter size in Romanov ewes. In conclusion, AMH is highly repeatable and its serum AMH level did not change during the oestrous cycle in Romanov sheep. In addition, AMH affects litter size and can be reliably used as a marker for litter size in Romanov sheep.

Symptoms, Lifetime Duration of Estrogen Exposure, and Ovarian Reserve Among Women Living With HIV: A Cross-Sectional Observational Study.

ABSTRACT: This cross-sectional observational study examined associations among symptom burden, lifetime duration of estrogen exposure, and serum antimüllerian hormone (AMH) levels among women living with HIV (n = 98) using bivariate bias-corrected Pearson correlations and multiple correspondence analyses. The mostly Black (85.6%) sample of women, with a mean age of 50 years (SD 12.6 years), exhibited no significant reproductive history factors and symptom burden interrelationships or significant associations between lifetime duration of estrogen exposure and symptoms. Predictably, serum AMH levels were lower among older women; however, less predictable were its significant relationships with months living with HIV (r = -0.362), months on ART (r = -0.270), and CD4+ T-cell nadir (r = 0.347). Symptom-symptom relationships support a fatigue, pain, sleep, anxiety, and depression symptom cluster. The hypotheses were not supported by cross-sectional observation. Further studies should explore variation in relationships between HIV, estrogen exposure, ovarian reserve, and AMH levels over time.

Comparison of dienogest or combinations with ethinylestradiol/estradiol valerate on the pain score of women with endometriosis: A prospective cohort study.

Endometriosis is one of the most frequent gynecologic disorders. The pathognomonic symptom of endometriosis is pelvic pain. The recommended pain medications are oral hormonal contraceptives, progestin therapy, danazol, gonadotropin-releasing hormone analogs, nonsteroidal anti-inflammatory drugs, and aromatase inhibitors. In this study, we aimed to compare the efficiency of costing dienogest (DNG) and low-cost oral contraceptives regarding visual analog scores (VAS) score of pelvic pain and also cancer antigen-125 (CA-125), anti-Mullerian hormone (AMH) levels, and size of endometrioma in the patients with endometriosis which is a chronic disease that requires a lifelong management plan. In our study, 18 to 45-year-old patients presented to our institution's gynecology and obstetrician department for various complaints over 2 years, and endometriosis diagnoses were included. Patients were divided into 3 groups (20 patients in each medication group) according to the given medication: cyclic DNG (Visanne) or 0.03 mg ethinylestradiol combined with 2 mg DNG (Dienille) or estradiol valerate combined with 2 mg DNG (Qlarista). We recorded all patients' CA-125/AMH values and VAS scores of pelvic pain. All patients gave informed consent. There was no statistically significant difference between pre-medication and post-medication levels of CA-125, AMH, VAS score, and cyst size in all groups. However, statistically, significant decreases were seen in the cyst size and VAS score, indicating response to therapy in all groups. In conclusion, we think it is more reasonable to use cost-effective oral contraceptive medications, which also cause common side effects, instead of costing DNG since all drugs have the same efficiency and success.

Prestimulation parameters predicting the pregnancy outcomes after IVF-ET in patients with unexplained infertility.

OBJECTIVE: Assisted Reproductive Technologies (ART) are considered to be the most effective treatment option for unexplained infertility. This study aims to investigate the pregnancy outcomes of women who received in-vitro fertilization-embryo transfer (IVF-ET) treatment for unexplained infertility and the contributing factors affecting these outcomes. PATIENTS AND METHODS: The present study included 789 consecutive women with unexplained infertility who were treated with IVF-ET at the ART Clinic of the Health Sciences University, Ankara Etlik Zübeyde Hanim Gynecology Training and Research Hospital between January 2007 and December 2019. The contributing factors affecting these outcomes, such as body mass index (BMI), basal follicle-stimulating hormone (FSH), and antimullerian hormone (AMH), were evaluated retrospectively. RESULTS: Clinical pregnancy per cycle was 19.8% among patients recruited. No statistically significant difference was detected in terms of age, infertility duration, and BMI of the patients who achieved pregnancy and who failed to get pregnant after IVF-ET treatment. The basal FSH level was found to be significantly lower (p=0.001), and the AMH level was significantly higher in patients who had clinical pregnancy (p=0.001). The basal AMH cut-off value was calculated to be 3.34 ng/mL, and the basal FSH cut-off value was calculated as 7.26 IU/L for the prediction of clinical pregnancy. CONCLUSIONS: IVF-ET treatment can be applied as a successful treatment option in unexplained infertility cases. Although the basal FSH and AMH values ​are not the cut-off values that have high sensitivity and specificity, they are considered to be associated with pregnancy rates.

Adipose-derived Mesenchymal Stem Cell Transplantation Improves Ovarian Function and Oocyte Quality in Aged Mice.

BACKGROUND/AIM: Age-related decline in the number of ovulations and ovum quality are major causes of female infertility, and stem cells have been reported to be effective in tissue regeneration. However, current therapeutic modalities are inadequate. This study investigated the effects of adipose-derived mesenchymal stem cells (ASCs) on ovarian functions in aged mice. MATERIALS AND METHODS: Following the characterization of ASCs using flow cytometry, the effects of ASCs on the number of ovulations, fertilization rate, and blastocyst-formation rate were investigated. In addition, the number of ovarian follicles and serum anti-Müllerian hormone (AMH) levels were examined. ASCs marked with Kusabira Orange were used to examine the location after cell administration. The quality of ovulated oocytes was analyzed using next-generation RNA sequencing. RESULTS: ASCs showed characteristics of mesenchymal stem cells and were distributed to various organs, including the ovarian stroma. The transplantation resulted in increased number of oocytes and ovulation in the ovaries and increased AMH values. Genetic analysis revealed improved oocyte quality and increased fertilization and blastocyst-formation rates. CONCLUSION: ASC therapy may be effective in improving fertility in older women.

Therapeutic effects of curculigoside on cyclophosphamide-induced premature ovarian failure in mice.

OBJECTIVE: The main purpose of this study was to elucidate the anti-apoptotic effects of curculigoside (CUR) on ovarian granulosa cells (GCs) in a mouse model of cyclophosphamide (CTX)-induced premature ovarian failure (POF). METHOD: Intraperitoneal injection of CTX (100 mg/kg body weight) induced POF in mice. Thirty-six female mice were divided into six groups: blank group; POF model group; low-dose CUR group; medium-dose CUR group; high-dose CUR group; and estradiol benzoate group. Mice were orally administered for 28 consecutive days. Twenty-four hours after the completion of treatment, mice were weighed and euthanized, and blood was collected from the eyeball under anesthesia. The ovaries were surgically separated and weighed, and the ovarian index was calculated. Hematoxylin-eosin (HE) staining was used to observe follicular development and corpus luteum morphology in the ovaries. Serum levels of follicle stimulating hormone (FSH), anti-Müllerian hormone (AMH) and estradiol (E2) were measured. Superoxide dismutase (SOD) activity, glutathione peroxidase (GSH-Px) content and malondialdehyde (MDA) levels in ovarian tissue were determined. The GC apoptosis level was measured. Western blotting was used to detect protein expression levels of Beclin-1, LC3, P62, AKT, p-AKT, mTOR and p-mTOR in the ovaries. RESULTS: The results showed that CUR can improve body weight and ovarian index; promote follicular development and reduce follicular atresia; improve FSH, AMH and E2 levels; downregulate MDA levels and restore antioxidant enzyme activity; inhibit the autophagy level; activate the AKT/mTOR signaling pathway; and alleviate GC apoptosis. CONCLUSION: CUR improves POF by activating the AKT/mTOR signaling pathway, inhibiting autophagy and alleviating GC apoptosis.

Conditional loss of Brca1 in oocytes causes reduced litter size, ovarian reserve depletion and impaired oocyte in vitro maturation with advanced reproductive age in mice.

BACKGROUND: An estimated 1 in 350 women carry germline BRCA1/2 mutations, which confer an increased risk of developing breast and ovarian cancer, and may also contribute to subfertility. All mature, sex steroid-producing ovarian follicles are drawn from the pool of non-renewable primordial follicles, termed the 'ovarian reserve'. The clinical implications of early ovarian reserve exhaustion extend beyond infertility, to include the long-term adverse health consequences of loss of endocrine function and premature menopause. We aimed to determine whether conditional loss of Brca1 in oocytes impacts ovarian follicle numbers, oocyte quality and fertility in mice with advancing maternal age. We also aimed to determine the utility of AMH as a marker of ovarian function, by assessing circulating AMH levels in mice and women with BRCA1/2 mutations, and correlating this with ovarian follicle counts. METHODS: In this study, we addressed a longstanding question in the field regarding the functional consequences of BRCA1 inactivation in oocytes. To recapitulate loss of BRCA1 protein function in oocytes, we generated mice with conditional gene deletion of Brca1 in oocytes using Gdf9-Cre recombinase (WT: Brca1fl/flGdf9+/+; cKO: Brca1fl/flGdf9cre/+). FINDINGS: While the length of the fertile lifespan was not altered between groups after a comprehensive breeding trial, conditional loss of Brca1 in oocytes led to reduced litter size in female mice. Brca1 cKO animals had a reduced ovarian reserve and oocyte maturation was impaired with advanced maternal age at postnatal day (PN)300, compared to WT animals. Serum anti-Müllerian hormone (AMH) concentrations (the gold-standard indirect marker of the ovarian reserve used in clinical practice) were not predictive of reduced primordial follicle number in Brca1 cKO mice versus WT. Furthermore, we found no correlation between follicle number or density and serum AMH concentrations in matched samples from a small cohort of premenopausal women with BRCA1/2 mutations. INTERPRETATION: Together, our data demonstrate that BRCA1 is a key regulator of oocyte number and quality in females and suggest that caution should be used in relying on AMH as a reliable marker of the ovarian reserve in this context.

Anti-Mullerian Hormone Assessment in Assisted Reproductive Technique Outcome and Natural Conception.

In recent years, the prevalence of infertility has increased, and appears to affect approximately one in six couples. Some of them must perform assisted reproductive techniques (ART) in order to achieve pregnancy. As a result, growing interest has arisen about predictive factors of pregnancy and live birth with and without ART. Anti-Mullerian hormone (AMH) is a glycoprotein discovered in the 1950s in male embryonic sexual differentiation. Later, in 1984, its role in folliculogenesis was reported: secreted by granulosa cells, this hormone is involved in the regulation of the recruitment of primordial follicles and in follicular growth. AMH assays were developed for women in 1990s, and the serum AMH level has rapidly become a crucial element in managing women's fertility. Based mainly on its ability to be a quantitative but indirect marker of ovarian reserve, the serum AMH assay is widely used in reproductive medicine and ART. This review summarizes current knowledge of the AMH assessment in the field of reproductive medicine. We focus on the role of AMH level to predict spontaneous pregnancy occurrence, ART outcomes, and fertility preservation outcomes.

Update on Assessment of Ovarian Reserve Testing.

Importance: Women are increasingly postponing pregnancy to achieve specific goals, and as it is known, the ovarian reserve (OR) declines with age, especially after the 30s. Assessing the OR helps in managing the care of women seeking pregnancy. Several OR tests (ORTs) have been advocated for assessing OR. Objectives: This review aims to discuss the different ORTs and the consequences of their use. Evidence Acquisition: For each topic, a PubMed search was conducted using MeSH terms. The following terms were used: ovarian reserve, ovarian reserve tests, anti-Müllerian hormone, antral follicle count, and diminished ovarian reserve. The search for further references was complemented by manual search, review, synthesis, and summarization of retrieved articles. Results: In this review, we clarified the concept of OR and the different ORTs and provided a guide for the ultrasound to assess OR. In addition, the clinical value of ORTs was highlighted to explain the implications of the results of these tests and how they can aid in patient counseling. Conclusion and Relevance: A number of ORTs are available to the clinician. Anti-Müllerian hormone and antral follicle count are the most valuable, but as with all ORTs, they are best used as screening, not diagnostic tests for OR. Screening for OR is most helpful when applied to specific groups.

Reproductive outcome after in vitro fertilization in endometriosis - key factors and implications.

Endometriosis is a benign chronic disease with a major impact on a woman's quality of life, mainly due to painful physical symptoms. Endometriosis is also a common cause of infertility caused by low ovarian reserve, distorted pelvic anatomy, and severe local inflammation with a direct negative impact on the quality of oocytes, embryos, and endometrium. We conducted a retrospective study between January 2019 and December 2023, including women with a history of surgery for endometriosis who underwent in vitro fertilization (IVF) to achieve pregnancy. Their reproductive outcome was compared with a group of patients with documented tubal obstruction. The aim of our study was to identify the factors associated with a positive impact on the pregnancy rate, specifically age, anti-Mullerian hormone (AMH), ovarian stimulation protocol, and types of gonadotropins used. We analyzed a group of 175 patients with endometriosis compared with 189 patients with tubal obstruction. The average age was similar between the two groups but with a difference in the average AMH value (1.63 ± 1.09 ng/mL vs. 2.55 ± 1.67 ng/mL). The most utilized ovarian stimulation protocol in both groups was the short gonadotropin-releasing hormone (GnRH) antagonist. The clinical pregnancy rate was 27.2% in the endometriosis group and 54.7% in the tubal obstruction group. Our study revealed that treatment with corifollitropin alfa in the endometriosis group was associated with a higher clinical pregnancy rate. AMH and age proved to be significant independent factors for the reproductive outcome.

Risk factors for empty follicle syndrome in diminished ovarian reserve patients undergoing intracytoplasmic sperm injection cycles: A retrospective observational analysis.

The aim of this study is to evaluate the risk factors for empty follicle syndrome (EFS) in patients with diminished ovarian reserve (DOR) undergoing an intracytoplasmic sperm injection cycle. In this retrospective study, patients with DOR were divided into 2 groups according to the presence of empty follicles on the day of oocyte retrieval. Patient age, body mass index (BMI), anti-Müllerian hormone (AMH), baseline follicle stimulating hormone (FSH) and estradiol (E2) levels, basal antral follicle count (AFC), total gonadotropin dose, and day of stimulation were recorded as risk factors. The association between EFS and these variables was assessed using the logistic regression method and ROC curve analysis. Increased BMI, low AMH, higher baseline FSH, low baseline AFC, higher gonadotropin dose, and longer day of ovulation induction were independent risk factors for EFS in patients with DOR. ROC curve analysis showed that BMI, AMH, baseline FSH, baseline AFC, higher gonadotropin dose, and longer ovulation induction days were predictive parameters in this group. According to the current study, higher BMI, lower AMH, higher baseline FSH, lower baseline AFC, higher gonadotropin dose and longer ovulation induction days were independent risk factors for EFS in patients with reduced ovarian reserve.

The clinical value of acupuncture for women with premature ovarian insufficiency: a systematic review and meta-analysis of randomized controlled trials.

Objective: The aim of this study was to evaluate the therapeutic implications of acupuncture on improving ovarian function in women diagnosed with premature ovarian insufficiency (POI) through the implementation of randomized clinical trials (RCTs). Methods: A comprehensive search of eight databases was conducted to identify RCTs up until 5 October 2023. The outcomes included the levels of sex hormones, antral follicle count (AFC), Kupperman score, and total effective rate. The risk of bias (RoB) tool was utilized to evaluate the quality of the included studies. In order to guarantee the robustness and reliability of the findings, subgroup and sensitivity analyses were performed to investigate potential sources of heterogeneity. Results: A total of 13 RCTs comprising 775 patients were included in the study. Acupuncture demonstrated significant efficacy in reducing follicle-stimulating hormone (FSH) [SMD = 0.83, 95% CI (0.27, 1.39), I 2 = 92%, p = 0.004], enhancing estradiol levels (E2) [SMD = 0.50, 95% CI (0.07, 0.93), p = 0.02, I 2 = 87%], and increasing anti-Müllerian hormone (AMH) [SMD = 0.24, 95% CI (0.05, 0.44), p = 0.01, I 2 = 8%], as well as improving the overall effective rate [RR = 1.22, 95% CI (1.10, 1.35), p < 0.01, I 2 = 14%]. Subgroup analysis revealed that compared with non-acupuncture therapy, the acupuncture with Chinese herbal medicine (CHM) and hormone replacement therapy (HRT) group exhibited a substantial reduction in FSH levels [SMD = 1.02, 95% CI (0.52, 1.51), I 2 = 60%, p < 0.01]. Furthermore, the acupuncture with CHM group also exhibited a substantial reduction [SMD = 4.59, 95% CI (1.53, 7.65), I 2 = 98%, p < 0.01]. However, only the acupuncture with CHM and HRT group demonstrated a significant increase in E2 levels [SMD = 0.55, 95% CI (0.23, 0.87), I 2 = 12%, p < 0.01]. Conclusion: Acupuncture has demonstrated superiority over non-acupuncture in diminishing serum FSH levels and increasing serum E2, AMH, and the overall efficacy rate in women diagnosed with POI. These research findings suggest the necessity for broader-scale research with meticulous designs to fully demonstrate the efficacy and safety of acupuncture in the treatment of women with POI.

Dietary acid load and risk of diminished ovarian reserve: a case-control study.

BACKGROUND: The epidemiologic evidence on the association between acid load potential of diet and the risk of diminished ovarian reserve (DOR) is scarce. We aim to explore the possible relationship between dietary acid load (DAL), markers of ovarian reserve and DOR risk in a case-control study. METHODS: 370 women (120 women with DOR and 250 women with normal ovarian reserve as controls), matched by age and BMI, were recruited. Dietary intake was obtained using a validated 80-item semi-quantitative food frequency questionnaire (FFQ). The DAL scores including the potential renal acid load (PRAL) and net endogenous acid production (NEAP) were calculated based on nutrients intake. NEAP and PRAL scores were categorized by quartiles based on the distribution of controls. Antral follicle count (AFC), serum antimullerian hormone (AMH) and anthropometric indices were measured. Logistic regression models were used to estimate multivariable odds ratio (OR) of DOR across quartiles of NEAP and PRAL scores. RESULTS: Following increase in PRAL and NEAP scores, serum AMH significantly decreased in women with DOR. Also, AFC count had a significant decrease following increase in PRAL score (P = 0.045). After adjustment for multiple confounding variables, participants in the top quartile of PRAL had increased OR for DOR (OR: 1.26; 95%CI: 1.08-1.42, P = 0.254). CONCLUSION: Diets with high acid-forming potential may negatively affect ovarian reserve in women with DOR. Also, high DAL may increase the risk of DOR. The association between DAL and markers of ovarian reserve should be explored in prospective studies and clinical trials.

Markers of Fertility in Adolescents With Chronic Endocrinopathies at Transition From Paediatric to Adult Care.

OBJECTIVE: During the process of transition from paediatric to adult health care, counselling concerning fertility is an important issue and is based mainly on serum markers of gonadal function. Here, we analysed these markers in adolescents with various underlying endocrine diseases at the time of transition. METHODS: After reaching near adult height and late puberty (girls: bone age [BA] ≥14 years, and boys: BA ≥16 years), we assessed stages of puberty according to Tanner and measured testes or ovarian volumes and serum markers of gonadal function (anti-Mullerian hormone [AMH], inhibin B, 17ß-estradiol, testosterone). RESULTS: One hundred and ten patients (56 females and 54 males) were included from May 2010 to March 2016 with multiple pituitary hormone deficiency (MPHD; n = 17), growth hormone deficiency (GHD; n = 35), Turner syndrome (TS; n = 27), short stature after being born small for gestational age (SGA; n = 20) and Klinefelter syndrome (KS; n = 11). Female and male adolescents exhibited mature secondary sexual characteristics. The levels of serum inhibin B and AMH were lower in TS and female MPHD than in GHD and SGA, each independently (p < 0.05). The levels of serum AMH were higher whereas serum inhibin B were lower in male MPHD and KS (p < 0.05). Ovary volumes were significantly smaller in patients with TS, and testicular volumes were smaller in patients with KS. CONCLUSIONS: After current established treatments with sex steroids, the development of secondary sexual characteristics was mature. However, impaired markers of fertility have been identified in patients with TS, KS and MPHD, reflecting gonadal dysgenesis in TS and KS, but gonadal immaturity in MPHD as gonadal gonadotropin stimulation is lacking throughout development. Consequently, in patients with MPHD, these markers cannot reliably predict individual fertility, which warrants consideration and incorporation in future treatment concepts.
