The association of thyroid autoimmunity with ovarian reserve in women with type 1 diabetes with and without polycystic ovary syndrome. Sci Rep 2024; 14:13223. [PMID: 38851814 PMCID: PMC11162496 DOI: 10.1038/s41598-024-63741-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Accepted: 05/31/2024] [Indexed: 06/10/2024] Open
Abstract
The aim of the study was to investigate the relation between thyroid autoimmunity (TAI), reflected as the presence of thyroid peroxidase antibodies (TPOAb), and parameters of ovarian reserve in women with type 1 diabetes (T1DM) and polycystic ovary syndrome (PCOS). We studied 83 euthyroid women with T1DM (age - 26 ± 5 years, BMI - 24 ± 3 kg/m2) - 12 with PCOS and positive TPOAb (PCOS + TPOAb), 29 with PCOS with negative TPOAb (PCOS + noTPOAb), 18 without PCOS with positive TPOAb (noPCOS + TPOAb), 24 without PCOS with negative TPOAb (noPCOS + noTPOAb). Serum concentrations of anti-Müllerian hormone (AMH), sex hormones, TSH, thyroid hormones and TPOAb were assessed. The prevalence of TAI was comparable between PCOS and noPCOS. We did not observe differences in hormonal profile or AMH concentration between two PCOS groups-PCOS + TPOAb and PCOS + noTPOAb (p > 0.05). Women with PCOS + TPOAb had lower FSH concentration and higher LH/FSH index than noPCOS + noTPOAb (p = 0.027; p = 0.019, respectively). Moreover, PCOS + TPOAb had lower oestradiol level than noPCOS + TPOAb (p = 0.041). AMH concentration was higher in both groups with PCOS, independent of TPOAb presence, than in noPCOS + noTPOAb (both p < 0.001). The presence of positive TPOAb titre was not related to the studied parameters of ovarian reserve - AMH and ovarian follicle number. In multiple linear regression analysis, the only significant predictor of AMH in the whole studied group with T1DM was total daily insulin dose U/kg (β = - 0.264; p = 0.022). The presence of TAI did not affect the hormonal profile or ovarian reserve in women with T1DM with and without PCOS.

Uterine histopathology and steroid metabolism in a polycystic ovary syndrome rat model. Mol Cell Endocrinol 2024; 585:112198.

Abstract
The aim of this study was to investigate uterine lesions, uterine endocrine status and expression of genes involved in uterine differentiation in a rat model of polycystic ovary syndrome (PCOS). The possible involvement of the androgen receptor (AR) was also investigated. PCOS rats showed an increased incidence of uterine epithelial and glandular lesions and elevated serum testosterone level, which was not detected in uterine tissue. Uterine 17β-estradiol, estrone and progesterone were detected in 100%, 75% and 50% of the animals, respectively. This was associated with a decrease in Star and an increase in Hsd17b2, Srd5a1 and Cyp19a1, suggesting that uterine steroids are not synthesized de novo in PCOS and that alterations in these enzymes may explain the absence of testosterone and low progesterone. In addition, ESR2 decreased and AR increased, suggesting possible steroid receptor crosstalk. Genes associated with uterine differentiation, PTEN and WNT5a, also showed reduced expression. PCOS rats treated with flutamide, an AR antagonist, were similar to PCOS rats in terms of uterine lesions, serum steroid levels, ESR2, PTEN and WNT5a expression. However, testosterone, AR and aromatase levels were similar to control rats, with decreased expression of ESR1 and HOXA10, suggesting that these expressions are AR dependent. Our results suggest that the primary cause of the observed uterine lesions in the PCOS rat model is the altered endocrine status and consequently changes in genes related to uterine differentiation.

Abstract
This study is aimed to investigate the characteristics of different obesity metabolic indexes [body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), cardiometabolic index (CMI), body roundness index (BRI), visceral adiposity index (VAI), and lipid aggregation products (LAP)] and their correlation with insulin resistance (IR) in patients with polycystic ovary syndrome (PCOS). The study was conducted on 140 subjects with PCOS and 133 control subjects aged 18-44 years. According to insulin resistance index (HOMA-IR) ≥ 2.69 and HOMA-IR < 2.69, PCOS group members were divided into insulin resistance group and non-insulin resistance group. Anthropometric and serological characteristics of the population with PCOS focused on calculating different obesity metabolic indexes and HOMA-IR. BMI, WC, WHR, WHtR, CMI, BRI, VAI, and LAP were significantly higher in PCOS patients than in the control group, and the differences were all statistically significant (P < 0.05); In the insulin resistance group of PCOS patients, BMI, WC, WHR, WHtR, CMI, BRI, VAI, and LAP were significantly higher than in the non-insulin resistance group (P < 0.05). In PCOS patients, BMI (r = 0.658, P < 0.001), WC (r = 0.0.662, P < 0.001), WHR (r = 0.377, P < 0.001), WHtR (r = 0.660, P < 0.001), CMI (r = 0.698, P < 0.001), BRI (r = 0.757, P < 0.001), VAI (r = 0.640, P < 0.001), and LAP (r = 0.767, P < 0.001) were positively correlated with IR. Obesity metabolic indexes associated with PCOS were elevated in the PCOS group compared to the control group, and in the PCOS insulin-resistant group compared to the non-insulin resistant group. Novel obesity metabolic indexes, especially CMI, BRI and LAP, might be more appropriate for evaluating the risk of concurrent IR in PCOS.

Abstract
Primary ovarian insufficiency (POI) is a complicated clinical syndrome characterized by progressive deterioration of ovarian function. Autoimmunity is one of the main pathogenic factors affecting approximately 10% to 55% of POI cases. This review mainly focuses on the role of autoimmunity in the pathophysiology of POI and the potential therapies for autoimmunity-related POI. This review concluded that various markers of ovarian reserve, principally anti-Müllerian hormone, could be negatively affected by autoimmune diseases. The presence of lymphocytic oophoritis, anti-ovarian autoantibodies, and concurrent autoimmune diseases, are the main characteristics of autoimmune POI. T lymphocytes play the most important role in the immune pathogenesis of POI, followed by disorders of other immune cells and the imbalance between pro-inflammatory and anti-inflammatory cytokines. A comprehensive understanding of immune characteristics of patients with autoimmune POI and the underlying mechanisms is essential for novel approaches of treatment and intervention for autoimmune POI.

Abstract
Abstract
Objectives Hyperandrogenism, a key feature of polycystic ovarian syndrome (PCOS), is caused by excess androgen secretion, most commonly of ovarian origin. Although the serum total testosterone (TT) levels have long been used as a traditional measure of hyperandrogenemia in women with PCOS, it is associated with many fallacies due to the fact that a component of TT is linked to sex hormone-binding globulin (SHBG). Recent research has discovered that measuring free testosterone levels and computing the free androgen index (FAI), which is a ratio of TT and SHBG, are better predictors of androgen excess in PCOS. The aim of this meta-analysis is to determine the association of FAI in diagnosing hyperandrogenism and its ability to discriminate PCOS from controls.
Materials and Methods The publicly available databases PubMed, Scopus and Web of Science were searched using MeSH terms, ‘Polycystic Ovarian Syndrome’ OR ‘PCOS’ OR ‘PCOD’ AND ‘Testosterone’ AND ‘Sex Hormone Binding Globulin’ OR ‘SHBG’ to collect the full-text articles for the retrieval of related data of case–control and cross-sectional studies. The studies quality was assessed using the Newcastle–Ottawa scale, and a sub-group analysis and publication bias between the studies was evaluated by funnel plot.
Statistical Analysis The R program (v4.0.3) and R packages ‘metafor’ and ‘dmetar’ were used for statistical analyses of quantitative data and the plots were generated using ‘ggplot2’ package through a comparison of pooled SMD by Egger's linear regression and Beggs-Mazumdar tests.
Results Twenty-four studies involving 7,847 participants including 3,290 controls and 4,557 PCOS were included in the meta-analysis. The pooled data analysis of the included studies showed that the PCOS women had higher FAI than controls, with SMD of 1.56 (95%CI 1.08–2.04; p < 0.01). The publication bias was tested using a funnel plot and Egger's regression asymmetry test, which revealed no risk of publishing bias (p = 0.1727). Additionally, the sub-group meta-analysis of geographic region revealed that FAI levels were more significant in PCOS subjects of Asia and Europe, compared with the American region.
Conclusion Overall, this meta-analysis indicates that FAI could be a reliable marker to differentiate PCOS patients from controls in Asian and European ethnicities.

Abstract
BSCKGROUND Polycystic ovary syndrome (PCOS) is a heterogeneous condition that increases the risk for serious health complications among women. Thus, in this study, we aimed to identify polymorphisms in the KiSS-1 and GPR54 genes and investigate the associations between KiSS-1, BMI, FSH, LH, and estradiol in Chinese women with PCOS. METHODS This study recruited women with PCOS (n = 60) and controls (n = 60). We collected blood samples and measured endocrine indicators (kisspeptin, FSH, LH-FSH ratio, estradiol, prolactin, and testosterone). PCR and Snapshots were performed to screen single nucleotide polymorphisms (SNPs) of the KiSS-1 and GPR54 genes. RESULTS Compared with the controls, endocrine and metabolic disturbances in women with PCOS were reflected in significantly higher levels of BMI, LH, LH-FSH ratio, prolactin, and testosterone. Serum kisspeptin levels were significantly higher and positively correlated with LH and T levels (p < 0.05). No identified SNPs of KiSS-1 and GPR54 showed significant differences in frequency between patients and controls. The mutant G allele was highly predisposed to polymorphism in the PCOS GPR54 gene r10407968. We observed a significant difference in estradiol (p = 0.023, p = 0.012) after comparing the values of LH, FSH, estradiol, progesterone, and testosterone among the three genotypes of rs4889 and rs5780218. The KiSS-1 rs4889 CC genotype and rs5780218 AA genotype showed significantly higher estradiol levels compared with the other two genotypes. CONCLUSIONS These results suggest that kisspeptin plays a potential role in the etiology of PCOS.

Abstract
Hirsutism is defined as the presence of terminal hair with male pattern distribution in women. While in the general population, hirsutism affects around 4-11% of women, it is the main manifestation of hyperandrogenism in women with polycystic ovary syndrome (PCOS), with a prevalence estimated at 65-75%. Hirsutism in PCOS is associated with both androgen excess and individual response of the pilosebaceous unit to androgens. The modified Ferriman-Gallwey (mFG) scoring system has been widely used in clinical practice to visually score excessive terminal hair, thus standardizing hirsutism evaluation and facilitating data comparison. Although a universal mFG score cutoff would be useful for comparisons, ethnic variations, as well as skin type and other factors, should be considered when evaluating hirsutism in distinct populations. In turn, androgen levels, measured by conventional techniques, have been shown to correlate poorly with the severity of hirsutism. Indeed, while most women with PCOS and hirsutism also have higher than reference values for serum androgen levels, some of them may not present with biochemical hyperandrogenism, representing a challenge to the diagnosis of PCOS. In this article, we critically review this not uncommon condition in women with PCOS presenting with hirsutism but normal androgen levels.

Abstract
As in women with polycystic ovary syndrome (PCOS), hyperinsulinemia is associated with anovulation in PCOS-like female rhesus monkeys. Insulin sensitizers ameliorate hyperinsulinemia and stimulate ovulatory menstrual cycles in PCOS-like monkeys. To determine whether hyperinsulinemia (>694 pmol/L), alone, induces PCOS-like traits, five PCOS-like female rhesus monkeys with minimal PCOS-like traits, and four control females of similar mid-to-late reproductive years and body mass index, received daily subcutaneous injections of recombinant human insulin or diluent for 6−7 months. A cross-over experimental design enabled use of the same monkeys in each treatment phase. Insulin treatment unexpectedly normalized follicular phase duration in PCOS-like, but not control, females. In response to an intramuscular injection of 200 IU hCG, neither prenatally androgenized nor control females demonstrated ovarian hyperandrogenic responses while receiving insulin. An intravenous GnRH (100 ng/kg) injection also did not reveal evidence of hypergonadotropism. Taken together, these results suggest that experimentally induced adult hyperinsulinemia, alone, is insufficient to induce PCOS-like traits in female rhesus monkeys and to amplify intrinsic PCOS-like pathophysiology.

STUDY QUESTION Is the presence of polycystic ovary syndrome (PCOS) associated with more adverse infant outcomes in mothers with different types of diabetes? SUMMARY ANSWER The presence of PCOS implies higher risks of total (medically indicated and spontaneously combined) and spontaneous preterm birth in mothers with non-insulin-treated type 2 diabetes and gestational diabetes mellitus (GDM), and lower risk of offspring being large for gestational age (LGA) in mothers with insulin-treated diabetes. WHAT IS KNOWN ALREADY PCOS is suggested to be an independent risk factor for adverse infant outcomes, and it is highly prevalent in mothers with diabetes. However, the impact of PCOS on the associations of different types of maternal diabetes with preterm birth and offspring birth sizes has not been reported. STUDY DESIGN, SIZE, DURATION This is a population-based cohort study including all live births between 1996 and 2014 in Finland. Children with concurrent maternal diagnoses that could cause signs and symptoms similar to PCOS were excluded. A total of 1 097 753 children were included. PARTICIPANTS/MATERIALS, SETTING, METHODS National registries were linked to identify births with maternal PCOS (n = 24 682), stratified by diabetes types. Logistic regression was used to examine the association of maternal PCOS and comorbid insulin-treated diabetes, non-insulin-treated type 2 diabetes or GDM with offspring LGA and small for gestational age (SGA). Generalized estimating equation was used to assess the risk of preterm birth in relation to maternal PCOS and diabetes. Potential interaction between PCOS and diabetes was evaluated on both additive and multiplicative scales. MAIN RESULTS AND THE ROLE OF CHANCE Using mothers with no PCOS and no diabetes as the reference and adjusting for maternal and birth factors, there were higher risks of total (odds ratio (OR) 2.84, 95% CI 2.21 − 3.66 vs. OR 1.91, 95% CI 1.77 − 2.07, P = 0.01) and spontaneous (OR 4.02, 95% CI 2.94 − 5.50 vs. OR 2.35, 95% CI 2.13 − 2.59, P = 0.001) preterm birth for those with PCOS in mothers with non-insulin-treated type 2 diabetes and higher risks of total (OR 1.42, 95% CI 1.27–1.58 vs. OR 0.89, 95% CI 0.86–0.91, P = 0.0001) and spontaneous (OR 1.80, 95% CI 1.59–2.05 vs. OR 1.01, 95% CI 0.98–1.05, P = 0.0001) preterm birth for those with PCOS in mothers with GDM. Among mothers with type 2 diabetes, further adjusting for maternal BMI eliminated the difference in preterm birth risks between those with and those without PCOS, and adjustment for infertility treatment and pre-eclampsia also reduced the preterm risks associated with PCOS significantly. For mothers with GDM, however, the risks of total and spontaneous preterm birth remained higher for those with PCOS following these aforementioned adjustments or stratified analysis. The risk of offspring being LGA was lower for those with PCOS than those without PCOS among mothers with insulin-treated diabetes (OR 18.90, 95% CI 14.21–25.14 vs. OR 32.04, 95% CI 29.79–34.46, P = 0.0001), showing departure from additivity (relative excess risk due to interaction −11.74, 95% CI −16.17 to −7.31, P < 0.001) and multiplicativity (P < 0.001). PCOS did not alter the risk estimate of preterm birth in mothers with insulin-treated diabetes or offspring LGA and SGA in mothers with type 2 diabetes or GDM. LIMITATIONS, REASONS FOR CAUTION The register-based diagnoses used in this study captured only women with PCOS seeking medical care and having live births. Including female infertility associated with anovulation as PCOS exposure was a risk for misclassification. Sample sizes for pregestational diabetes were small. Insulin purchase during pregnancy in those without a diabetes diagnosis was not accounted for in the analysis. For patients treated with insulin or other medications, we were unable to assess how they complied with such prescriptions. Also, maternal BMI was recorded only once in early pregnancy, thus the potential influence of gestational weight gain on birth outcomes could not be examined. Data on the causes for preterm birth were not available from the registers. WIDER IMPLICATIONS OF THE FINDINGS The presence of PCOS implied higher risks of total and spontaneous preterm birth in mothers with type 2 diabetes or GDM, and lower risk of offspring being LGA in mothers with insulin-treated diabetes. The higher risks of preterm birth added by PCOS could be explained by prepregnancy BMI or in part by infertility treatment and pre-eclampsia in maternal non-insulin-treated type 2 diabetes, but not in maternal GDM. The differential effects of PCOS on the associations of different types of maternal diabetes with infant outcomes have implications for preventative strategies and clinical counseling for affected pregnancies.

Abstract
Anti-müllerian hormone (AMH) is 1 of the 2 testicular hormones involved in male development of the genitalia during fetal life. When the testes differentiate, AMH is secreted by Sertoli cells and binds to its specific receptor type II (AMHR2) on the müllerian ducts, inducing their regression. In the female fetus, the lack of AMH allows the müllerian ducts to form the fallopian tubes, the uterus, and the upper part of the vagina. The human AMH gene maps to 19p13.3 and consists of 5 exons and 4 introns spanning 2,764 bp. The AMHR2 gene maps to 12q13.13, consists of 11 exons, and is 7,817 bp long. Defects in the AMH pathway are the underlying etiology of a subgroup of disorders of sex development (DSD) in 46,XY patients. The condition is known as the persistent müllerian duct syndrome (PMDS), characterized by the existence of a uterus and fallopian tubes in a boy with normally virilized external genitalia. Approximately 200 cases of patients with PMDS have been reported to date with clinical, biochemical, and molecular genetic characterization. An updated review is provided in this paper. With highly sensitive techniques, AMH and AMHR2 expression has also been detected in other tissues, and massive sequencing technologies have unveiled variants in AMH and AMHR2 genes in hitherto unsuspected conditions.

Comparative study of the clinico-trichoscopic response to treatment of hirsutism with long pulsed (1064 nm) Nd:YAG laser in idiopathic hirsutism and polycystic ovarian syndrome patients. Lasers Med Sci 2021; 37:545-553.

Abstract
Treatment of hirsutism is usually resistant, and from medical management to laser hair reduction, the treatment of hirsutism and its assessment are the most challenging. The aim of the study was to compare the response to treatment by laser hair reduction with long pulsed (1064 nm) Nd:YAG laser in patients of idiopathic hirsutism and polycystic ovarian syndrome (PCOS) by clinical and trichoscopic assessment. A hospital-based comparative, observational prospective study was carried out on female patients with hirsutism over a period of 18 months with two groups of participants: fifty women with idiopathic hirsutism (group A) and fifty with PCOS (group B). Laser hair reduction was done with long pulsed (1064 nm) Nd:YAG laser in both groups up to six sessions, 4 weeks apart and followed for 3 months post last laser session. After the sixth session of laser hair reduction, excellent response (> 75% reduction) from baseline was seen in 70% of patients in group A and in 54% of patients in group B. After 3 months of follow-up of the last laser session, it was found that the results persisted in patients with idiopathic cause than in those due to PCOS, seen both clinically and trichoscopically with decrease in hair shaft thickness, hair shaft colour, terminal vs. vellus hair ratio and hair density per cm2. Hirsutism due to idiopathic cause responds better to laser hair reduction with long pulsed (1064 nm) Nd:YAG laser than that due to PCOS, due to underlying hormonal imbalance in the latter group. Follow-up of only up to 3 months after last laser session was done and tricoscan was not done.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is an endocrine disorder that commonly affects women of childbearing age and has been associated with metabolic and reproductive abnormalities. Only a few studies have investigated metabolic traits in women with PCOS in Latin America. Therefore, we conducted a systematic review to provide an overview of the available evidence on the metabolic profile of Latin American women with PCOS. METHODS We searched PubMed, Cochrane Central Register of Controlled Trials, and Embase databases for cross-sectional, case-control, or cohort studies focusing on populations of countries in South and Central America and Mexico, published until October 31, 2019. We selected studies that reported the diagnostic criteria for PCOS. In the absence of a control group, we included studies if they reported relevant metabolic data. RESULTS The initial search yielded 4878 records, of which 41 studies were included in the systematic review. Sample sizes ranged from 10 to 288 in PCOS groups and from 10 to 1500 in control groups. The prevalence of phenotypes A and B (classic PCOS) ranged from 65.8% to 87.5% as reported in studies from Argentina, Brazil, and Chile. Metabolic syndrome ranged from 33.3% to 44.0% for phenotype A, from 15.0% to 58.0% for phenotype B, from 11.9% to 36.0% for phenotype C, and from 14.2% to 66.0% for phenotype D. Women with PCOS had higher body mass index, waist circumference, blood pressure, glucose, and homeostasis model assessment index as well as a more adverse lipid profile than those without PCOS. CONCLUSIONS Evidence from the present systematic review suggests that anthropometric and metabolic profiles are worse in women with PCOS who live in different Latin American countries than in women without PCOS living in the same region. Additional studies assessing metabolic comorbidities, such as diabetes, and distinct PCOS phenotypes in different Latin American countries are warranted and may produce invaluable information for primary and secondary prevention of PCOS in the region. This systematic review was registered with PROSPERO under number CRD42016038537. SYSTEMATIC REVIEW REGISTRATION PROSPERO, identifier CRD42016038537.

Abstract
Background Hyperandrogenism with or without polycystic ovarian syndrome is seen in adolescents with type 1 diabetes (T1D), especially those with suboptimal control. Objective To assess the effect of metformin on hyperandrogenism and ovarian function in adolescents with T1D. Methods This prospective study included 28 T1D females showing signs of hyperandrogenism. History taking (detailed diabetes history and menstrual history) and anthropometric measurements (weight, height, body mass index [BMI], waist and hip circumference) were initially performed, and then the patients were assessed for the manifestations of hyperandrogenism (acne, hirsutism as well as pelvic ultrasound [U/S] for ovarian morphology). Biochemical evaluation for ovulation (progesterone assessment during the luteal phase), sex steroids (estradiol, testosterone, dehydroepiandrosterone sulfate [DHEAS] and androstenedione), prolactin, glycemic control (hemoglobin A1c [HbA1c]) and gonadotropin levels (follicle stimulating hormone [FSH] and luteinizing hormone [LH]) was done. Patients were subjected to 500 mg metformin twice daily orally for 1 year, and then the patients were re-evaluated for clinical and biochemical parameters. Results Metformin therapy resulted in a significant reduction in weight (p = 0.001), BMI (p = 0.002), acne (p = 0.008), hirsutism score (0.007), LH (p = 0.008), testosterone (p < 0.001) and androstenedione levels (p = 0.028) in adolescent girls with T1D. Regarding menstrual irregularities, there was a significant reduction in the number of patients with oligomenorrhea (68%) with a p value of <0.001. However, there were no significant reduction in the daily insulin requirements (p = 0.782) or HbA1c (p = 0.068). Nausea and/or abdominal pain were the commonly reported side effects of metformin (64%). Conclusions Metformin as an insulin sensitizing agent improved the BMI and cycle regularity together with clinical and biochemical hyperandrogenism in T1D adolescent girls. However, it did not improve their glycemic control.

Abstract
Background: Thyroid carcinoma is the most common endocrine malignancy. Surgery is the standard therapeutic approach for patients with differentiated thyroid carcinoma (DTC), followed by radioiodine (RAI) therapy if indicated. For women with DTC, the effects of RAI therapy on gonadal and reproductive function are an important consideration. This study aimed to evaluate the effects of RAI therapy on ovarian function. Methods: A total of 33 premenopausal women were enrolled in this study. Serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, and anti-Müllerian hormone (AMH) levels during the early follicular phase were measured before and 3, 6, and 12 months after RAI therapy. The Friedman and Wilcoxon tests were used to detect changes in FSH, AMH, LH, and estradiol levels induced by RAI therapy over time. Results: The patients' ages ranged from 21 to 38 years, with a mean age of 31.15 ± 4.83 years. The median follow-up was 19 months (range 4-26 months). The median AMH levels were 3.25 ng/mL (range 0.32-17.42 ng/mL), 1 ng/mL (range 0.01-3.93 ng/mL), 1.13 ng/mL (range 0.08-6.12 ng/mL), and 1.37 ng/mL (range 0.09-6.1 ng/mL) before and at 3, 6, and 12 months after RAI therapy, respectively. The median FSH levels were 6.6 mIU/mL (range 3.78-15.5 mIU/mL), 5.83 mIU/mL (range 4.19-35.36 mIU/mL), 7.71 mIU/mL (range 4.24-16.25 mIU/mL), and 7.04 mIU/mL (range 4.93-19.96 mIU/mL) before and at 3, 6, and 12 months after RAI therapy, respectively. The AMH levels were higher before than after RAI therapy (p = 0.001). The AMH levels did not differ significantly between the three time points (p > 0.05). The FSH, LH, and estradiol levels were similar before and after RAI therapy (p > 0.05). Conclusion: AMH is considered an important marker of ovarian reserve. Ovarian reserve decreased after RAI therapy. More attention may be needed when considering RAI therapy for patients with reduced ovarian reserve.

Abstract
Background The objective of this study was to describe the association between luteinizing hormone (LH)/
follicle-stimulating hormone (FSH) ratio and demographic variables and maturation stage of oocytes in insulin-
resistant and insulin-sensitive patients with polycystic ovary syndrome (PCOS) in comparison with control
group. Materials and Methods In this case-control study, 60 patients with in vitro fertilization (IVF)/intracytoplas-
mic sperm injection (ICSI) indication were subdivided into 3 groups as follow: 20 subjects were assigned to
control (fertile women with male infertility history) group, 20 subjects with PCOS were insulin resistant (IR)
and 20 subjects with PCOS were insulin sensitive (IS). After puncture, retrieved oocytes were classified into
metaphase II (MII) as mature and in metaphase I (MI) or germinal vesicle stage (GV) as immature. Regres-
sion analyses were used to explore the association between MII oocyte number and demographic and clinical
variables. Results LH/FSH ratio was significantly higher in PCOS-IR women compared to controls but not significantly dif-
ferent from that of PCOS-IS group. PCOS-IR women had lower MII oocyte number compared with that of controls.
According to multiple regression analysis, the number of previous assisted reproductive technology (ART) cycles was
negatively associated with the number of MII oocytes. Conclusion Insulin resistance can be associated with reductions in MII oocyte number in patients with PCOS.

Abstract
OBJECTIVE Women with type 1 diabetes have increased risk of infertility compared to women without diabetes even after adjustment for irregular menses, but aetiologies are incompletely understood. Our aim was to examine the prevalence of abnormalities in ovarian markers consistent with polycystic ovary syndrome in women with type 1 diabetes and associations with irregular menses and diabetes-specific variables. DESIGN, PATIENTS AND MEASUREMENTS We conducted a secondary analysis of women in the Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications Study (DCCT/EDIC), a randomized trial and observational follow-up of intensive insulin therapy for type 1 diabetes. We included women with anti-Müllerian hormone (AMH) measurements among women not using oral contraceptives (n = 187). Initial AMH and testosterone measures were performed between EDIC years 1 and 4. History of irregular menses was assessed annually. RESULTS The median age of women was 35 (interquartile ratio 29, 40) years; 133 (35%) had elevated AMH and 62 (17%) reported irregular menses. Twelve per cent of women had relative elevations in total testosterone. In multivariable models, lower insulin dosages were associated with higher AMH concentrations (P = .0027), but not diabetes duration, glycemic control, body mass index or irregular menses. Neither irregular menses nor diabetes-specific variables were associated with testosterone concentrations. CONCLUSIONS Among women with type 1 diabetes in their thirties, abnormalities in ovarian markers are common and not associated with irregular menses and thus may partially account for decreased fecundity in women with type 1 diabetes.

Abstract
Higher androgen levels are observed in non-pregnant women with diabetes. Whether this hormonal profile is found during pregnancy is unknown. The aim of this study was to determine the sexual steroids levels in pregnant women with pregestational type 2 (T2D) and gestational diabetes (GD) compared to healthy control (C) pregnant women during the second half of pregnancy. A prospective study of 69 pregnant women with T2D (n = 21), GD (n = 24) and control (C, n = 24) was followed up during the second half of gestation. Clinical assessments and blood samples were collected at 26.7 (25-27.8); 34 (32-34.9) and 37.5 (37-40) weeks of gestation. Androgens, sex hormone-binding globulin (SHBG), estrogens, estradiol/testosterone (E/T) ratio, insulin, glucose, HOMA-IR, were measured. Testosterone, insulin and homeostatic model assessment of insulin resistance (HOMA-IR) levels were higher in T2D compared with C at each sampling point during pregnancy, even after adjusting for BMI and age. Estrogens levels and estradiol/testosterone ratio were lower in T2D and GD compared with C. Hyperandrogenemia, and higher insulin resistance is observed in T2D, but not in GD during pregnancy. Decreased estrogen and E/T ratio found in T2D and GD suggests a diminished aromatase activity during gestation. T2D and GD are associated with specific changes in sexual steroids and insulin resistance levels during pregnancy.

Abstract
PURPOSE A single prior study conducted in Chilean women has shown that women with type 1 diabetes mellitus (T1DM) and polycystic ovary syndrome (PCOS) have a normal serum anti-Müllerian hormone (AMH) concentrations despite polycystic ovarian morphology. As it is not clear why women with PCOS+T1DM would not have an elevated concentrations of AMH, we hypothesize that women with T1DM and PCOS have a similar hormonal profile and serum AMH levels as is observed in classic PCOS. METHODS We studied 89 women: 37 with T1DM (16 with PCOS+T1DM, 21 with T1DM/no-PCOS), 36 with PCOS (PCOS) and 16 healthy women (control group) matched for age and body mass index (BMI). A clinical examination, determination of serum AMH and sex hormones, and an ultrasonographic evaluation of the ovaries were performed for all study participants. RESULTS Serum AMH concentrations were significantly higher in women with PCOS+T1DM than in those with T1DM/no-PCOS (p<0.001) and was not different between both PCOS groups (PCOS vs PCOS+T1DM). Ovarian volume and ovarian follicle count did not differ between women with PCOS+T1DM and PCOS. The number of ovarian follicles was higher in patients with PCOS+T1DM and PCOS versus the control (p=0.007, p<0.001) and versus cases of T1DM/no-PCOS (p<0.001, p<0.001, respectively). Cross-sectionally, AMH concentrations correlated positively with luteinizing hormone (LH) (r=0.4; p<0.001), testosterone (r=0.2, p=0.02), ovarian volume (r=0.4, p<0.001) and follicle count (r=0.7, p<0.001). In both groups, PCOS+T1DM and PCOS, AMH was related to LH (r=0.5; p=0.036; r=0.3; p=0.031) and to ovarian follicle number (r=0.7; p<0.001; r=0.4; p=0.006). In multivariate logistic regression analysis, serum AMH was the only predictor of PCOS in T1DM women (OR=1.73; 95% CI 1.07-2.79, p=0.023). CONCLUSIONS Women with T1DM and PCOS have a similar hormonal profile and serum AMH concentrations as observed in classic PCOS.

Abstract
BACKGROUND A few small studies have reported increased prevalences of polycystic ovary syndrome (PCOS) and symptoms of androgen excess in women with type 1 diabetes. PURPOSE We performed a systematic review and meta-analysis of studies evaluating androgen excess symptoms and PCOS in women with type 1 diabetes. DATA SOURCES The Entrez-PubMed and Scopus electronic databases were used. STUDY SELECTION We selected studies addressing androgen excess signs, symptoms, and disorders in girls, adolescents, and adult women with type 1 diabetes. DATA EXTRACTION The main outcome measures were prevalences of PCOS, hyperandrogenemia, hirsutism, menstrual dysfunction, and polycystic ovarian morphology (PCOM). DATA SYNTHESIS Nine primary studies involving 475 adolescent or adult women with type 1 diabetes were included. The prevalences of PCOS and associated traits in women with type 1 diabetes were 24% (95% CI 15-34) for PCOS, 25% (95% CI 17-33) for hyperandrogenemia, 25% (95% CI 16-36) for hirsutism, 24% (95% CI 17-32) for menstrual dysfunction, and 33% (95% CI 24-44) for PCOM. These figures are considerably higher than those reported earlier in the general population without diabetes. LIMITATIONS The data collected in the original studies were heterogeneous in age, race, ethnicity, and criteria used for the diagnosis of PCOS; yet, we used a quality-effects model in the meta-analyses to overcome this limitation. CONCLUSIONS PCOS and its related traits are frequent findings in women with type 1 diabetes. PCOS may contribute to the subfertility of these women by a mechanism that does not directly depend on glycemic/metabolic control among other negative consequences for their health. Hence, screening for PCOS and androgen excess should be included in current guidelines for the management of type 1 diabetes in women.

Abstract
age with type 1 diabetes mellitus about the endogenous androgens and on their relations to the parameters of diabetes control. Forty-two women were examined, they did not use contraceptives for at least three months prior to the examination. A multivariate regression analysis showed that the daily insulin dose, the fasting glycemia and the HbA1c values and patient´s age correlated negatively with dehydroepiandrosterone sulfate, dehydroepiandrosterone and prolactin levels. The testosterone/dehydroepiandrosterone sulfate ratio correlated positively with daily insulin dose and patient´s age. In contrast to adrenal androgens the values of other hormones, including total and free testosterone, androstenedione, dihydrotestosterone, estradiol, LH, FSH, 17-OH-P, progesterone and cortisol revealed no significant correlation. To conclude, significant relations between the glucose control parameters and the adrenal androgens and prolactin were demonstrated. These relationships should be considered as an important factor influencing diabetes control so the additional cardiovascular risk in women with DM1.

Abstract
OBJECTIVE Menstrual irregularities, reproductive abnormalities, and androgen excess are reported to be more prevalent in women with type 1 diabetes (T1D). The objective of this study was to investigate the prevalence of menstrual irregularities, reproductive abnormalities, and androgen excess among women with T1D and their age-matched controls. METHODS A survey requesting information regarding menstrual and reproductive histories was administered to all participants. Results were stratified according to age (18 to 40, 40 to 50, and >50 years). RESULTS There were no significant differences between women with and without diabetes in age at menarche, cycle length, or androgen excess in any group. Women who self-reported difficulty with glycemic control were more likely to report irregular menses than controls (P = .04). Among women who reported ever being pregnant, there were fewer pregnancies (P = .02) and live births (P = .002) in women with T1D. Women with T1D reported a lower frequency of oral contraceptive use (P = .003), despite being less likely to smoke (P = .016). CONCLUSION Menstrual and reproductive abnormalities were not observed more frequently in women with T1D in this study. Subtle but measurable differences in menstrual and reproductive function were confined to the subgroup of women who perceived poor control of their diabetes. Additional prospective studies of T1D and menstrual and reproductive function would be useful.

Abstract
There is an increased incidence of autoimmune thyroid disease (AITD) in women with infertility. We hypothesized that serum anti-Müllerian hormone (AMH) levels will be lower in premenopausal women with AITD than controls. We evaluated ovarian reserve in women with AITD (n = 85) and healthy controls (n = 80), all <40 years old. Detailed data on reproductive history were obtained. Gonadotrophins, steroids, AMH, and inhibin B levels were measured during the follicular phase. The number of pregnancies as well as live births was lower in women with AITD (p < 0.01). No difference was observed in terms of FSH, estradiol, and inhibin B. AMH levels were lower in AITD women than in controls (1.16 + 0.17 versus 1.28 + 0.25 ng/ml, mean + SD, p = 0.001). According to the multiple regression analysis, even after age adjustment, AITD was significantly and independently affected AMH levels (t = 2.674, p = 0.008). Women with AITD seem to have a diminished ovarian follicular reserve and measurement of serum AMH level has the potential to be used to predict this comorbidity.

Abstract
We evaluated the association of hirsutism and oligomenorrhea (persistent menstrual cycles > 45 days) as screening criteria for the detection of biochemical hyperandrogenism (BH) and polycystic ovaries (PCOM) during adolescence and determined which androgens, granulosa cell hormone, ultrasonographic parameters have the best association with polycystic ovary syndrome (PCOS). Hirsute girls with oligomenorrhea (N = 26 Hirs/Oligo group) and non-hirsute girls with regular cycles (N = 63, C group) were studied. Prevalence of BH and PCOM, diagnostic performance of androgens and ultrasound parameters for PCOS diagnosis were analyzed. BH and PCOM prevalence were higher in the Hirs/Oligo girls than in the C girls (76.9% versus 25.5%; 92.3% versus 33.3%, respectively; p < 0.0001). A complete PCOS phenotype (Hirs/Oligo with BH and PCOM) was observed in 73.1% of the Hirs/Oligo group. The presence of both BH and PCOM was observed in 7.9% of the C group. The parameters with the best diagnostic performance were free androgen index ≥6.1, testosterone ≥2.4 nmol/L, follicle number ≥12 and ovarian volume ≥10 ml anti-Müllerian hormone (AMH) exhibited a low diagnostic accuracy. Hirsutism and persistent menstrual cycle over 45 days are highly associated with BH and PCOM suggesting that the presences of both criteria are necessary for the diagnosis of PCOS during adolescence.

Abstract
BACKGROUND A high prevalence of hyperandrogenism has been reported in women with type 1 diabetes (T1D). Metformin has been used as a therapeutic agent in patients with polycystic ovarian syndrome and in T1D patients without hyperandrogenism. This study sought to determine the effect of metformin on hyperandrogenism and ovarian function in adolescents with T1D. METHODS We recruited 24 girls with T1D. The participants had hyperandrogenism and displayed suboptimal metabolic control. The patients were enrolled in a randomized, double-blind, placebo-controlled trial. One group received metformin (850 mg bid) and the other group received a placebo. Treatment was administered for 9 months. Ovulation, steroids and gonadotropin levels were evaluated. RESULTS Metformin treatment was associated with decreases in testosterone, free androgen index, androstenedione, 17-OH progesterone and estradiol levels. The girls who were treated with placebo showed stable steroid, gonadotropin and sex hormone-binding globulin levels during the analysis. No differences were observed in the Ferriman-Gallwey scores, ovulation rates, HbA1c levels or daily insulin doses of the girls treated with metformin compared with the placebo group. CONCLUSION Treating hyperandrogenic T1D adolescents with metformin significantly decreased the serum androgens compared to the placebo, but metformin therapy did not significantly affect clinical parameters, such as hirsutism, ovulation and metabolic control.

Abstract
Much is written about how difficult it is to deal with diabetes during adolescence, and rightly so. Less is understood as to how puberty may be an accelerator of vascular complications. With the increase in childhood diabetes, complication risks need to be revisited in relation to puberty and the secular increase in adiposity. Recent data suggest greater risk for severe vascular complications in those with diabetes during puberty, compared with young people who develop diabetes after puberty. It is also widely recognized that higher hemoglobin A1c (HbA1c) results are often seen during the pubertal period. This article will review complication outcomes in relation to puberty and examine mechanisms by which puberty may modify risk above glycemic exposure, and possible gender disparities in the risk of complications in the adolescent period.

Abstract
There appears to be an epidemic of both obesity and polycystic ovary syndrome (PCOS) in the world today. However, obesity per se is not a part of the phenotype in many parts of the world. Obesity is likely not a cause of PCOS, as the high prevalence of PCOS among relatively thin populations demonstrates. However, obesity does exacerbate many aspects of the phenotype, especially cardiovascular risk factors such as glucose intolerance and dyslipidemia. It is also associated with a poor response to infertility treatment and likely an increased risk for pregnancy complications in those women who do conceive. Although most treatments of obesity, with the exception of bariatric surgery, achieve modest reductions in weight and improvements in the PCOS phenotype, encouraging weight loss in the obese patient remains one of the front-line therapies. However, further studies are needed to identify the best treatments, and the role of lifestyle therapies in women of normal weight with PCOS is uncertain.

Abstract
Inhibins A and B are gonadal factors which are important in fertility. Their use as predictors of female reproductive health has centred on their application to ovarian cancer, Anorexia Nervosa, Down Syndrome and preeclampsia. Inhibin B also provides an index of the endocrine feedback relationship between the ovary and pituitary particularly when the ovarian follicle reserve is low. These applications are relevant in monitoring the onset of the menopause transition, ovarian recovery following chemotherapy and disturbances in pubertal development. Currently, these applications have only found widespread use in Down Syndrome and ovarian cancer. Activins, on the other hand, appear to have a limited application.

BACKGROUND The functional reproductive alterations seen in women with type 1 diabetes (T1D) have changed as therapy has improved. Historically, patients with T1D and insufficient metabolic control exhibited a high prevalence of amenorrhea, hypogonadism and infertility. This paper reviews the impact of diabetes on the reproductive axis of female T1D patients treated with modern insulin therapy, with special attention to the mechanisms by which diabetes disrupts hypothalamic-pituitary-ovarian function, as documented mainly by animal model studies. METHODS A comprehensive MEDLINE search of articles published from 1966 to 2012 was performed. Animal model studies on experimental diabetes and human studies on T1D were examined and cross-referenced with terms that referred to different aspects of the gonadotropic axis, gonadotrophins and gonadal steroids. RESULTS Recent studies have shown that women with T1D still display delayed puberty and menarche, menstrual irregularities (especially oligomenorrhoea), mild hyperandrogenism, polycystic ovarian syndrome, fewer live born children and possibly earlier menopause. Animal models have helped us to decipher the underlying basis of these conditions and have highlighted the variable contributions of defective leptin, insulin and kisspeptin signalling to the mechanisms of perturbed reproduction in T1D. CONCLUSIONS Despite improvements in insulin therapy, T1D patients still suffer many reproductive problems that warrant specific diagnoses and therapeutic management. Similar to other states of metabolic stress, T1D represents a challenge to the correct functioning of the reproductive axis.

Abstract
OBJECTIVE To obtain insight into the effects of androstenedione on ovarian folliculogenesis and oogenesis. DESIGN Experimental study. SETTING St. Marianna University School of Medicine. ANIMAL(S) Prepubertal (14-day-old) BDF1 female mice. INTERVENTION(S) Early secondary follicles were isolated from the ovaries and were cultured individually in vitro with or without androstenedione (10(-11) to 10(-5) M) for 12 days. Thereafter, the follicles were treated with hCG and epidermal growth factor (EGF). MAIN OUTCOME MEASURE(S) Diameters and morphology of follicles and oocytes; E(2) and P secretion; and chromatin configuration and expression of growth differentiation factor 9 (GDF9) in oocytes were examined. RESULT(S) Early secondary follicles developed to the preovulatory stage. Androstenedione treatments increased the follicle diameters, reduced survival rates of follicles, and promoted the formation of follicles with abnormal morphology, including misshapen oocyte. The secretion of E(2) and P was significantly higher in androstenedione-exposed follicles. Androstenedione prevented the alteration in chromatin configuration and reduced oocyte GDF9 expression. When follicles cultured with androstenedione were treated with hCG and EGF, the first polar body exclusion, chromosome alignment on metaphase plate, and spindle assembly were inhibited in the oocytes. CONCLUSION(S) These results demonstrate that excess androgen induces abnormalities in the morphology and function of developing oocytes, which impairs oocyte meiotic competence.

Abstract
Adolescence is a critical period for girls with type 1 diabetes mellitus (T1D). Reproductive issues, such as menstrual abnormalities, risk of an unplanned pregnancy, and contraception, should be addressed during this phase of life. This paper reviews several reproductive issues that are important in the care of adolescents, including pubertal development, menstrual abnormalities, ovulatory function, reproductive problems, the effects of hyperglycemia, contraception, and treatment of an unplanned pregnancy. A review of the literature was conducted. A MEDLINE search January 1966 to March 2011 was performed using the following MESH terms: puberty, menarche, ovary, polycystic ovary syndrome, menstruation, contraception, contraception-barrier, contraceptives-oral-hormonal, sex education, family planning services, and pregnancy in adolescence. This literature search was cross-referenced with an additional search on diabetes mellitus-type 1, diabetes complications, and pregnancy in diabetes. All published studies were searched regardless of the language of origin. Bibliographies were reviewed to extract additional relevant sources.

Abstract
Reproductive dysfunction is associated with obesity. We previously showed that female mice with diet-induced obesity (DIO) exhibit infertility and thus serve as a model of human polycystic ovary syndrome (PCOS). We postulated that differential insulin signaling of tissues leads to reproductive dysfunction; therefore, a comparison of insulin signaling in reproductive tissues and energy storage tissues was performed. Pituitary-specific insulin receptor knockout mice were used as controls. High-fat diet-induced stress, which leads to insulin resistance, was also investigated by assaying macrophage infiltration and phosphorylated Jun NH(2)-terminal kinase (pJNK) signaling. In lean mice, reproductive tissues exhibited reduced sensitivity to insulin compared with peripheral metabolic tissues. However, in obese mice, where metabolic tissues exhibited insulin resistance, the pituitary and ovary maintained insulin sensitivity. Pituitaries responded to insulin through insulin receptor substrate (IRS)2 but not IRS1, whereas in the ovary, both IRS1 and IRS2 were activated by insulin. Macrophage infiltration and pJNK signaling were not increased in the pituitary or ovary of lean mice relative to DIO mice. The lack of inflammation and cytokine signaling in the pituitary and ovary in DIO mice compared with lean mice may be one of the reasons that these tissues remained insulin sensitive. Retained sensitivity of the pituitary and ovary to insulin may contribute to the pathophysiology of PCOS.

Abstract
PCOS, a major cause of anovulatory sterility, is associated with obesity, insulin resistance and chronic inflammation. New evidence suggests that the immune system aggravates the clinical features of PCOS. Our aim was to study the immune, metabolic and endocrine features of a mouse model of PCOS elicited by androgenisation using dehydroepiandrosterone (DHEA). We observed a significant weight gain and insulin resistance in DHEA-androgenised mice, coupled with the formation of ovarian follicular cysts. DHEA up-regulated the expression of vascular cell adhesion molecule (VCAM)-1 and intercellular adhesion molecule (ICAM)-1 in the granulosa cell layer of the majority of cysts, and VCAM-1 expression in the theca cell layer of all follicles and cysts. The expression of these markers was low in control tissue. Peritoneal cells from PCOS-mice showed enhanced production of inflammatory cytokines, suggesting an association between chronic inflammation and PCOS. In addition, DHEA-androgenisation induced the activation of CD4(+) cells both in vivo and in vitro, and their expression of the respective ligands for VCAM-1 and ICAM-1, VLA-4 and LFA-1, as assessed in vitro. CD4(+) cells were present in androgenised ovaries, especially in the granulosa cell layer of cysts with high VCAM-1 expression. Herein, we present novel evidence that the immune system is activated systemically and locally in a mouse model for PCOS. We propose that VCAM-1 is involved in aggravating PCOS symptoms by promoting leukocyte recruitment to the ovaries and perpetuating local inflammation. These findings offer novel therapeutic opportunities for PCOS, such as blockage of VCAM-1 expression.

Abstract
BACKGROUND American Samoa and Samoa are now characterized by one of the world's highest levels of adult overweight and obesity. Our objective was to investigate patterns of menstrual cyclicity reported by Samoan women and examine the relationship to adiposity and select hormone levels. METHODS A cross-sectional analysis was performed among Samoan women, aged 18-39 years (n = 322), using anthropometric and biomarker measures of adiposity and reproductive health, including insulin, adiponectin, testosterone, sex hormone-binding globulin, free androgen index (FAI) and mullerian-inhibiting substance (MIS). Menstrual regularity was assessed from self-reported responses. Multivariable models were estimated to adjust for potential confounding of the associations between menstrual patterns and other measures. RESULTS A high proportion of the women (13.7%) reported oligomenorrhea or amenorrhea (OM/AM). More than three-quarters, 80.7%, of women were either overweight or obese, using Polynesian-specific criteria, and OM/AM was significantly associated with higher BMI. Abdominal circumference and insulin levels were significantly higher, and adiponectin levels were lower, in those who reported OM/AM versus regular menstruation. The FAI was higher in women with increased BMI. MIS levels declined with age, more slowly in those reporting OM/AM. CONCLUSIONS Self-reported OM/AM was associated with an elevated BMI, abdominal adiposity and serum insulin, and with reduced adiponectin levels. These findings support a high rate of metabolic syndrome, and perhaps PCOS and reproductive dysfunction, among Samoan women.

Abstract
OBJECTIVE Elevated anti-Müllerian hormone (AMH) and adrenal androgen levels have been observed during childhood in girls at risk of developing polycystic ovarian syndrome (PCOS). The aim of this study was to evaluate ovarian function and adrenal steroid levels in prepubertal girls with type 1 diabetes mellitus (T1D). DESIGN Cross-sectional study. PATIENTS/MEASUREMENTS: We evaluated hormonal and ultrasonographic characteristics in girls with T1D (N = 73) and compared them to characteristics found in a control group of healthy girls (N = 86). Data are reported as geometric means (95% CI). RESULTS Prepubertal girls with T1D had higher levels of AMH (29·1 pmol/l (23·2-36·3) vs 20·9 pmol/l (16·6-26·1), P = 0·038), inhibin B (arithmetic mean: 16·7 pg/ml (11·6-21·7) vs 11·7 pg/ml (10·0-13·5), P = 0·044) and dehydroepiandrosterone sulphate (DHEAS) (0·3 nmol/l (0·2-0·6) vs 0·2 nmol/l (0·1-0·3)) than controls (P = 0·045). During puberty, decreasing AMH levels were observed in girls with T1D only (P < 0·0001). Girls with T1D in Tanner stages 4-5 had lower AMH levels than their paired healthy controls (10·1 pmol/l (7·4-13·9) vs 15·7 pmol/l (11·6-21·3), respectively, P = 0·047). CONCLUSIONS Our observations indicate that prepubertal girls with T1D may exhibit similar endocrine findings to those of other girls at risk of developing PCOS. The elevated levels of AMH and inhibin B suggest that higher numbers of follicles are present in the ovary during childhood in these patients and that insulin treatment may act as a local growth factor. In addition, AMH levels differed in prepubertal and pubertal girls, suggesting that the effect of T1D on ovarian folliculogenesis changes once gonadotrophin levels rise during puberty.

Abstract
The incidence and the rate of progression of nondiabetic renal disease is generally greater in men compared with age-matched women, suggesting that the female sex is protective and/or that the male sex is a risk factor for the development and progression of nondiabetic renal disease. In diabetes, even though the male sex still appears to be a risk factor, this relationship is not as strong as it is in nondiabetic renal disease. Experimental evidence suggests that both estrogens and androgens play an important role in the pathophysiology of renal disease. Thus one of the potential mechanisms for the absence of a clear sex difference in the setting of diabetes may be alterations in sex hormone levels. Indeed, studies suggest that diabetes is a state of an imbalance in sex hormone levels; however, whether these changes correlate with the decline in renal function associated with diabetes is unclear. Furthermore, diabetic renal disease rarely develops before puberty, and the onset of puberty accelerates microalbuminuria, supporting the idea of the involvement of sex hormones in the development and progression of the disease. However, other than a handful of experimental studies indicating that treatment with or removal of sex hormones alters the course of diabetic renal disease, very few studies have actually directly examined the correlation between sex hormones and the disease development and progression. Further studies are necessary to determine the precise contribution of sex hormones in the pathophysiology of diabetic renal disease to develop novel and potentially sex-specific therapeutic treatments.
