Polycystic ovaries are a common finding in untreated female to male transsexuals

Prevalence of Intersex/Differences in Sex Development and Primary Gonadal Insufficiency in a Pediatric Transgender Population

Purpose

This study aims to assess the prevalence of intersex variations/differences in sex development (I/DSDs), associated adrenal conditions, and primary gonadal insufficiency in children with gender dysphoria.

Methods

We performed a comprehensive review of the medical records for individuals who carried the diagnostic codes for gender dysphoria in addition to intersex and/or other conditions associated with sex steroid variations among patients evaluated by pediatric endocrinologists from 2013 to 2022.

Results

We found that 9 of 612 (1.5%) transmasculine (TM) and 4 of 215 (1.9%) transfeminine patients had detectable I/DSDs. Although most patients were diagnosed with I/DSDs before evaluation of gender dysphoria, 4 of 13 (30.7%) were diagnosed with I/DSDs after being referred to endocrinology for gender dysphoria. In all cases, diagnoses were made by the endocrinologists evaluating for gender dysphoria. An additional 0.7% of TM patients were diagnosed with distinct hyperandrogenic adrenal conditions, and 1% of TM patients were diagnosed with primary ovarian insufficiency.

Conclusion

The low, but clinically relevant, prevalence of I/DSDs, distinct adrenal conditions, and primary gonadal insufficiency in this transgender population supports the need for access to individualized expert medical care. Specifically, multidisciplinary clinics with experience in endocrinology may provide specialized support for the transgender community.

The prevalence, phenotype and cardiometabolic risk of polycystic ovary syndrome in treatment-naïve transgender people assigned female at birth

PURPOSE

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder among women of reproductive age. We aimed to investigate the prevalence and phenotypic characteristics of PCOS in testosterone treatment-naïve transgender people assigned female at birth (AFAB), as well as to determine whether cardiometabolic risk factors vary based on the presence of PCOS and its components.

METHODS

Evaluation of 112 testosterone treatment-naïve transgender adults AFAB for PCOS and its individual components, including androgen excess, ovulatory dysfunction and polycystic ovarian morphology (PCOM).

RESULTS

In our cohort, 79.5% of transgender individuals AFAB had at least one component of PCOS. The prevalence of PCOS was 38.4% (43/112). Phenotype C was the most common phenotype (17.8%), followed by phenotype B (10.7%). Transgender individuals AFAB with at least one component of PCOS had higher blood pressure (BP) measurements and higher fasting plasma glucose levels compared to those with none. Sixty-one subjects (54%) had hyperandrogenism (HA), with 20 (17.9%) having HA without other components of PCOS. When compared to those without HA, transgender individuals AFAB with HA had higher body mass index (BMI), BP, triglyceride and lower HDL-cholesterol levels.

CONCLUSION

PCOS and androgen excess appear to be prevalent among transgender people AFAB. Transgender individuals AFAB with HA or PCOS may exhibit an unfavorable cardiometabolic risk profile compared to those without any PCOS component. Assessment of androgen excess and the specific components of PCOS at baseline could inform long-term management.

Prevalence of Polycystic Ovarian Syndrome in Young and Adolescent Transmasculine Patients Presenting for Gender-Affirming Care

STUDY OBJECTIVE

To determine the incidence of polycystic ovarian syndrome (PCOS) and hyperandrogenism among adolescent transmasculine patients presenting to a tertiary care referral center for gender-affirming care METHODS: This was a retrospective study of adolescent transmasculine patients presenting to Cleveland Clinic for gender-affirming hormone therapy. The diagnostic criteria were adolescent-specific as defined by the international evidence-based guideline for PCOS management and included oligomenorrhea and/or anovulation with clinical and/or biochemical hyperandrogenism after exclusion of other androgen excess disorders.

RESULTS

The described transgender population had a prevalence of PCOS of 23.8%. The transmasculine patients who met the criteria for PCOS had both higher levels of androgens and higher body mass indexes when compared with the patients without PCOS. Additionally, the patients with PCOS had higher rates of dyslipidemia.

CONCLUSION

The prevalence of PCOS among transmasculine patients may be higher compared with the general population. Transmasculine patients with PCOS should be counseled regarding the long-term health implications associated with PCOS and screened appropriately to minimize risks.

Low-dose spironolactone combats dyslipidemia and hepatic inflammation by modulating PCSK9 in rat model of polycystic ovarian syndrome

Polycystic ovarian syndrome (PCOS) is the most common endocrine disorder among women and it is associated with overt metabolic derangement. Circulating lipids are regulated by proprotein convertase subtilisin/kexin type 9 (PCSK9) which blocks low density lipoprotein (LDL) receptors especially in the liver. The liver is highly vulnerable in dyslipidemia as lipid accumulation leads to progression of non-alcoholic fatty liver disease (NAFLD). An array of scientific endeavours hold that low-dose spironolactone (LDS) is beneficial as intervention for PCOS traits, but this claim is yet to be fully elucidated. The aim of this study was to investigate the effect of LDS on dyslipidemia and hepatic inflammation in rats with letrozole (LET)-induced PCOS and to assess the possible involvement of PCSK9 in these effects. Eighteen female Wistar rats were randomly assigned into 3 groups. The control group received vehicle (distilled water; p.o.), LET-treated group received letrozole (1 mg/kg; p.o.), LET+LDS-treated group received LET plus LDS (0.25 mg/kg, p.o.) for 21 days. Exposure to LET increased body and hepatic weights, plasma and hepatic total cholesterol (TC), TC/HDL, LDL, interleukin-6, MDA, PCSK9, ovarian degenerated follicles and hepatic NLRP3 intensity, reduced GSH and normal ovarian follicles. Interestingly, LDS averted dyslipidemia, NLRP3-dependent hepatic inflammation and ovarian PCOS traits. It is evident herein that LDS ameliorates PCOS traits and combats dyslipidemia and hepatic inflammation in PCOS by a PCSK9-dependent mechanism.

Gender diversity in adolescents with polycystic ovary syndrome

OBJECTIVES

The objective of our study was to describe the prevalence of gender diverse (GD) youth  among adolescents with polycystic ovary syndrome (PCOS).

METHODS

We conducted a retrospective chart review on patients who met NIH criteria for PCOS in our Multidisciplinary Adolescent PCOS Program (MAPP). We compared those with PCOS to MAPP patients who did not meet PCOS criteria as well as to non-PCOS patients from the Adolescent Specialty Clinic (ASC). Variables analyzed included gender identity, androgen levels, hirsutism scores, and mood disorders. We used chi-square, Fisher's exact, t-tests, and Wilcoxon rank sum tests to compare groups.  Gender identities self-reported as male, fluid/both or nonbinary  were pooled into the GD category.

RESULTS

Within the MAPP, 7.6% (n=12) of PCOS youth self-identified as GD compared to 1.8% (n=3) of non PCOS youth (p=0.01, chi-square). When compared to non-PCOS GD adolescents from ASC (4.4%; n=3), the difference to PCOS youth was no longer significant (p=0.56). Among MAPP patients, gender diversity was associated with higher hirsutism scores (p<0.01), but not higher androgen levels. In PCOS, depression/anxiety was higher in GD vs cisgender youth (100% vs. 37.6%, p<0.01 and 77.8% vs. 35.8%, p=0.03 respectively).

CONCLUSIONS

Gender diversity was observed more commonly in those meeting PCOS criteria. PCOS GD youth were more hirsute and reported more depression/anxiety. Routine screening for differences in gender identity in comprehensive adolescent PCOS programs could benefit these patients, as alternate treatment approaches may be desired to support a transmasculine identity.

Multicenter Analysis of Cardiometabolic-related Diagnoses in Transgender and Gender-Diverse Youth: A PEDSnet Study

CONTEXT

Studies on cardiometabolic health in transgender and gender-diverse youth (TGDY) are limited to small cohorts.

OBJECTIVE

This work aimed to determine the odds of cardiometabolic-related diagnoses in TGDY compared to matched controls in a cross-sectional analysis, using a large, multisite database (PEDSnet).

METHODS

Electronic health record data (2009-2019) were used to determine odds of cardiometabolic-related outcomes based on diagnosis, anthropometric, and laboratory data using logistic regression among TGDY youth vs controls. The association of gender-affirming hormone therapy (GAHT) with these outcomes was examined separately among TGDY. TGDY (n = 4172) were extracted from 6 PEDSnet sites and propensity-score matched on 8 variables to controls (n = 16 648). Main outcomes measures included odds of having cardiometabolic-related diagnoses among TGDY compared to matched controls, and among TGDY prescribed GAHT compared to those not prescribed GAHT.

RESULTS

In adjusted analyses, TGDY had higher odds of overweight/obesity (1.2; 95% CI, 1.1-1.3) than controls. TGDY with a testosterone prescription alone or in combination with a gonadotropin-releasing hormone agonist (GnRHa) had higher odds of dyslipidemia (1.7; 95% CI, 1.3-2.3 and 3.7; 95% CI, 2.1-6.7, respectively) and liver dysfunction (1.5; 95% CI, 1.1-1.9 and 2.5; 95% CI, 1.4-4.3) than TGDY not prescribed GAHT. TGDY with a testosterone prescription alone had higher odds of overweight/obesity (1.8; 95% CI, 1.5-2.1) and hypertension (1.6 95% CI, 1.2-2.2) than those not prescribed testosterone. Estradiol and GnRHa alone were not associated with greater odds of cardiometabolic-related diagnoses.

CONCLUSION

TGDY have increased odds of overweight/obesity compared to matched controls. Screening and tailored weight management, sensitive to the needs of TGDY, are needed.

Short chain fatty acid, acetate restores ovarian function in experimentally induced PCOS rat model

BACKGROUND

Polycystic ovarian syndrome (PCOS) is pathogenically characterized with hyperandrogenism and metabolic alterations, which often result in ovarian changes and infertility in women of reproductive age. Epigenetic changes have been linked to the development of PCOS. However, the involvement of epigenetic regulator, histone deacetylase (HDAC) in PCOS-driven ovarian dysfunction is not clear. Howbeit, the present study hypothesized that acetate, an HDAC inhibitor (HDACi) would protect against ovarian dysfunction in experimentally induced PCOS.

MATERIALS AND METHODS

Female Wistar rats weighing 120-150 g were randomly divided into four groups (n = 6). The groups received vehicle, sodium acetate (200 mg/kg), letrozole (1 mg/kg) and letrozole with acetate by oral gavage respectively. The administrations were done daily for 21 days.

RESULTS

The rat model of PCOS had increased body weight and ovarian weight, 1-hr postload glucose and plasma insulin, testosterone and LH/FSH ratio as well as reduced insulin sensitivity and plasma 17-β estradiol and sex hormone binding globulin. This model of PCOS in addition showed a significant increase in plasma and ovarian triglyceride, total cholesterol, TNF-α and HDAC, and ovarian malondialdehyde as well as a significant reduction in ovarian glutathione peroxidase/reduced glutathione and NrF2 with the histology of ovarian tissues showing disrupted morphology with significant increase in the number of degenerated follicles compared with control group. These alterations were however attenuated when treated with HDACi, acetate.

CONCLUSION

Altogether, the present results suggest that acetate protects ovarian function with evidence of normal growing follicles and enhanced circulating 17-β estradiol by inhibition of HDAC.

Low dose spironolactone-mediated androgen-adiponectin modulation alleviates endocrine-metabolic disturbances in letrozole-induced PCOS

Polycystic ovarian syndrome (PCOS), is a multifactorial endocrine disorder in women of reproductive age. It usually associates with metabolic disorders (MDs), which aggravates the risk of infertility, cardiometabolic events and associated comorbidities in women with PCOS. Adiponectin, a circulating protein produced by adipocytes, which has been suggested to inversely correlate with MDs. Spironolactone, a non-selective mineralocorticoid receptor (MR) antagonist, has been in wide clinical use for several decades. Herein, we investigated the effects of low dose spironolactone (LDS) and the role of adiponectin in endocrine-metabolic disturbances in experimentally-induced PCOS rats. Eighteen female Wistar rats (160-180 g) were randomly allotted into 3 groups and treated with vehicle (p.o.), letrozole (LET; 1 mg/kg) and LET + LDS (0.25 mg/kg), once daily for 21 days, respectively. The results showed that LET-treated animals had features of PCOS, characterized by elevated plasma testosterone and prolactin, increased body weight gain and ovarian weight as well as disrupted ovarian cytoarchitecture and degenerated follicles. Additionally, elevated fasting blood glucose, 1 h-postload glucose and plasma insulin, impaired glucose tolerance, insulin resistance, reduced insulin sensitivity, increased plasma and ovarian lipid profile, plasma lipid peroxidation, TNF-α, IL-6 and decreased plasma glutathione peroxidase and glutathione content were observed. These alterations were associated with decreased circulating adiponectin and were reversed when treated with LDS. The present results suggest that LDS ameliorates endocrine-metabolic disturbances and inflammation-related comorbidities associated with LET-induced PCOS by modulating circulating androgen-adiponectin status.

Clinical needs for transgender men in the gynecologic oncology setting

Transgender men remain at risk for gynecologic malignancies, but are an underserved population. Members of the transgender community experience discrimination and have experiences that contribute to health disparities, including in gynecology and oncology. While efforts have been made within the United States to reduce inequalities experienced by members of this community, many needs in the clinical setting remain. Increased education and training among providers and healthcare professionals, and general improvements towards understanding barriers to health screening and health resource uptake may reduce some disparities. Additional research towards screening and cancer surveillance among this community will be necessary to understand any potential additional risks and survival disparities experienced by transgender men. This review focuses on barriers and clinical needs for transgender men in the gynecologic oncology setting, and suggestions for moving forward to improve care for this patient population.

Physiological and Metabolic Characteristics of a Cohort of Transgender and Gender-Diverse Youth in the United States

PURPOSE

The purpose of this study was to describe baseline physical and laboratory characteristics of participants in the largest prospective study of transgender and gender-diverse (TGD) youth in the United States.

METHODS

Participants were recruited from four clinics which specialize in the care of TGD youth before starting either GnRH analogs for pubertal suppression or gender-affirming hormone treatment. Anthropometric and laboratory measurements were abstracted from the medical chart. Baseline characteristics including height, weight, body mass index, blood pressure, and laboratory measurements were compared with those of age-matched National Health and Nutritional Examination Survey comparison group.

RESULTS

Seventy-eight TGD youth with a median age of 11 years (range 8-14 years) were recruited before pubertal suppression, of whom 41 (53%) were designated male at birth, and 296 participants with a median age of 16 years (range 12-20 years) were recruited before beginning gender-affirming hormones, of whom 99 (33%) were designated male at birth. The mean high-density lipoprotein cholesterol was lower in the study participants when compared with that of National Health and Nutritional Examination Survey participants (50.6 ± 12.3 mg/dL vs. 53.3 ± 13.3 mg/dL, p = .001). Otherwise, the study cohorts were similar in terms of body mass index, proportion of overweight and obesity, blood pressure, and baseline laboratory variables.

CONCLUSIONS

Before starting gender-affirming treatment, TGD youth are physiologically similar to the general population of children and adolescents in the United States, with the exception of slightly lower high-density lipoprotein cholesterol. Evaluation of this cohort over time will define the physiological effects of pubertal blockade and gender-affirming hormone treatment.

Ovarian stimulation outcomes among transgender men compared with fertile cisgender women

PURPOSE

To compare assisted reproductive technology (ART) outcomes among transgender men with those of fertile cisgender women.

METHODS

This retrospective cohort study included 12 transgender men, six with no testosterone exposure and six after testosterone treatment, and 12 cisgender women (oocyte donors) who underwent ART in our institution between June 2017 and December 2019. Statistical analyses compared ART data and outcomes between three groups: cisgender women, transgender men without testosterone exposure, and transgender men after testosterone exposure. Comparisons were also made between transgender men with and without testosterone exposure.

RESULTS

The transgender men with no testosterone exposure (23.3 ± 4 years) were significantly younger than the transgender men who had undergone testosterone treatment (30.3 ± 3.8 years; P = 0.012) and the cisgender women (29.1 ± 3.1 years; P = 0.004). The amount of FSH used for ovulation induction (1999 ± 683 mIU/mL) was significantly lower among transgender men without prior testosterone exposure compared with that among cisgender women (3150 ± 487 mIU/mL; P = 0.007). There were no differences in the peak estradiol levels, the number of oocytes retrieved, the number of MII oocytes, and the oocyte maturity rates between the three groups. Five out of six testosterone-treated transgender men underwent embryo cryopreservation, and they all achieved good-quality embryos.

CONCLUSIONS

Transgender men have an excellent response to ovulation stimulation even after long-term exposure to testosterone. Oocyte/embryo cryopreservation is, therefore, a feasible and effective way for them to preserve their fertility for future biological parenting.

Ovarian Histopathology in Transmasculine Persons on Testosterone: A Multicenter Case Series

BACKGROUND

As transmasculine persons utilize androgen gender affirming hormone therapy as a part of transition, guidance has been lacking on the effects of the therapy on the ovaries, especially for those who may desire retention.

AIM

To describe the ovarian histopathology of transmasculine persons on testosterone therapy following oophorectomy at the time of hysterectomy performed for gender affirmation.

METHODS

This was a multicenter case series study of transmasculine patients on testosterone therapy who underwent hysterectomy with oophorectomy for gender affirmation between January 2015 and December 2017 at 5 tertiary care referral centers. Patients were identified by their current procedural and International Classification of Diseases codes.

OUTCOMES

Pre-, perioperative, and pathologic data were obtained from the electronic medical records and ovarian tissue descriptions from pathology reports were grouped into the following classifications: (i) simple/follicular cysts; (ii) polycystic ovaries; (iii) complex cysts; (iv) endometriomas; (v) other masses; (vi) atrophy; and (vii) normal.

RESULTS

85 patients were included in the study. At the time of oophorectomy, the mean age and body mass index of the cohort were 30.4 ± 8.4 years and 30.2 ± 7.3 kg/m², respectively, and the average interval from the initiation of testosterone to oophorectomy was 36 0.3 ± 37.9 months. On examination of ovarian histopathology, 49.4% (42) of specimens were found to have follicular/simple cysts, 5.9% (5) were polycystic, and 38.8% (33) had normal pathology. For those specimens with volume documented (n = 41), the median volume was 9.6 (range 1.5-82.5) cm³. There was no association between the duration of testosterone therapy or body mass index and the presence of cysts in the ovaries.

CLINICAL IMPLICATIONS

The results of this study reported benign histopathology in ovaries of a large cohort of transmasculine persons on testosterone which should be included when counseling patients on ovarian retention, as transmasculine patients may choose to retain their ovaries while on testosterone for a variety of reasons (including no desire to undergo surgery, desire for backup sex steroids, and potential use for future fertility).

STRENGTHS & LIMITATIONS

This is a large multicenter study seeking to address the uncertainty in present counseling surrounding ovarian conservation in transmasculine persons on testosterone therapy. Its limitations included its retrospective nature and inability to address ovarian function after testosterone discontinuance.

CONCLUSION

In this cohort of transmasculine patients on testosterone therapy undergoing hysterectomy with oophorectomy for gender affirmation, ovarian histopathology was benign in all the specimens.

Oocyte retrieval outcomes among adolescent transgender males

PURPOSE

To compare fertility preservation (FP) outcomes among adolescent transgender males with those of cisgender females.

METHODS

This retrospective cohort study included nine adolescent transgender males and 39 adolescent cisgender females who underwent FP between January 2017-April 2019 and September 2013-April 2019, respectively. The transgender males were referred before initiating testosterone, and the cisgender females were referred due to cancer diagnosis before starting anticancer treatment. Statistical analyses compared assisted reproductive technology (ART) data and FP outcomes between two groups.

RESULTS

Basal FSH levels (5.4 ± 1.7 mIU/mL) and AFC (19.8 ± 5.6) of all transgender males were normal compared with standard references. The mean age of transgender males and cisgender females was similar (16.4 ± 1.1 vs 15.5 ± 1.3 years, respectively, P = 0.064). The amount of FSH used for stimulation was significantly lower among the former compared with the latter (2416 ± 1041 IU vs 4372 ± 1877 IU, P < 0.001), but the duration of stimulation was similar (12.6 ± 4.0 and 10.1 ± 2.8 days, P = 0.086). Peak estradiol level was significantly higher among transgender males compared with cisgender females (3073 ± 2637 pg/mL vs 1269 ± 975 pg/mL, respectively, P = 0.018), but there were no significant differences in number of retrieved oocytes between the two groups (30.6 ± 12.8 vs 22 ± 13.2, P = 0.091), number of MII oocytes (25.6 ± 12.9 vs 18.8 ± 11.2, P = 0.134), or maturity rates (81.5 ± 10.0% vs 85.4 ± 14.6%, P = 0.261).

CONCLUSIONS

Adolescent transgender males have an excellent response to ovulation stimulation before initiating testosterone treatment. Oocyte cryopreservation is, therefore, a feasible and effective way for them to preserve their fertility for future biological parenting.

Very low dose spironolactone protects experimentally-induced polycystic ovarian syndrome from insulin-resistant metabolic disturbances by suppressing elevated circulating testosterone

Polycystic ovarian syndrome (PCOS) is the most common endocrinological disorder in women of reproductive age and hyperandrogenism is a prominent feature of PCOS resulting in infertility and increased risk of developing metabolic disorders including insulin resistance (IR), abdominal adiposity, glucose intolerance and cardiovascular diseases. Spironolactone (SPL), a non-selective mineralocorticoid receptor (MR) antagonist, has been in wide clinical use for several decades. In this study, we investigated the effects of SPL on IR and metabolic disturbances in letrozole-induced PCOS rats. Eighteen adults female Wistar rats were randomly divided into 3 groups and treated with vehicle, letrozole (LET; 1 mg/kg) and LET + SPL (SPL; 0.25 mg/kg), p.o. once daily for 21 consecutive days. Results showed that LET treatment induced PCOS characterised by elevated plasma testosterone and luteinizing hormone (LH) accompanied with increased body weight and visceral adiposity, IR, glucose intolerance, dyslipidemia and altered histomorphological ovaries. Treatment with SPL however attenuated the elevated testosterone in LET-induced PCOS model accompanied with a reversal in all the observed alterations. Taken together, analysis of the physical, biochemical and histological evidences shows that the protective effect of this very low dose spironolactone may be through its anti-androgenic mechanism.

Tetragonia tetragonioides (Pall.) Kuntze Regulates Androgen Production in a Letrozole-Induced Polycystic Ovary Syndrome Model

Tetragonia tetragonioides (Pall.) Kuntze (TTK) is a medicinal plant traditionally used to treat various diseases such as diabetic, inflammatory, and female-related disorders. Polycystic ovary syndrome (PCOS) is a common endocrinological disorder in women of reproductive age, and hyperandrogenism is a prominent feature of PCOS resulting in anovulation and infertility. In this study, we investigated the effects of a TTK extract on androgen generation and regulation of steroidogenic enzymes in vitro and in vivo. Human adrenocortical NCI-H295R cells were used to assess the effects of TTK extract on production of dehydroepiandrosterone and testosterone, as well as the protein expression of steroidogenic enzymes. Further, a letrozole-induced PCOS rat model was used in vivo to assess whether dietary administration of TTK extract restores normal hormones and reduces PCOS symptoms. TTK extract significantly inhibited forskolin (FOR)-induced androgen production in NCI-H295R cells and serum luteinizing hormone, testosterone, and follicular cysts, but not estradiol, were reduced in letrozole-induced PCOS rats orally administered the TTK extract. In addition, TTK extract inhibits androgen biosynthesis through the ERK-CREB signaling pathway, which regulates CYP17A1 or HSD3B2 expression. TTK extract could be utilized for the prevention and treatment of hyperandrogenism and other types of PCOS.

Towards a further understanding of prenatal thyroid theory of homosexuality: Autoimmune thyroiditis, polycystic ovary syndrome, autism and low birth weight

Research into the neurobiological origins of same-sex attraction is inconclusive. A recent theory of homosexuality posited that maternal thyroid dysfunction during pregnancy is associated with an increased rate of homosexual orientation in offspring. Relevant studies from the prenatal thyroid model perspective were reviewed, the major findings of which are as follows: i) An increased prevalence of Hashimoto’s disease in lesbian women suggests a maternal and even familial presence of the same autoimmune thyroid disease. Female-tomale transsexuals and lesbian women were also reported to have higher rates of polycystic ovary syndrome (PCOS). Over the last several years, reports suggesting a strong link between PCOS and thyroid autoimmunity have accumulated. ii) The increased risk of autism spectrum disorders (ASD) in the offspring of mothers with thyroid autoimmunity in pregnancy and the association between ASD and gender dysphoria indicate a link between maternal thyroid dysfunction and gender dysphoria/same-sex attraction in the offspring. iii) The high risk of miscarriage and retarded fetal growth in pregnancies of mothers who give birth to homosexual offspring can be explained by the impact of maternal thyroid dysfunction during pregnancy. This perspective review highlights relevant research findings and integrates them into the prenatal thyroid model of homosexuality. A better understanding of the mechanisms involved in the generation of same-sex orientation will contribute to the betterment of individual lives, as well as of society.

Hormonal and Surgical Treatment Options for Transgender Men (Female-to-Male)

Untreated transgender men face serious negative health care outcomes. Effective medical, surgical, and mental health treatment ameliorates these risks. Although the research is not as robust as would be ideal, hormone treatment is effective and generally well tolerated with few serious medical risks. Surgeries carry serious risks; but for most transgender men, the benefits outweigh the risks. This review describes current evidence-based medical treatments for transgender men and provides an overview of surgical therapy to enable practitioners to discuss these options with their transgender male patients.

Interactions between androgens, FSH, anti-Müllerian hormone and estradiol during folliculogenesis in the human normal and polycystic ovary

BACKGROUND

Androgens, FSH, anti-Müllerian hormone (AMH) and estradiol (E2) are essential in human ovarian folliculogenesis. However, the interactions between these four players is not fully understood.

OBJECTIVES AND RATIONALE

The purpose of this review is to highlight the chronological sequence of the appearance and function of androgens, FSH, AMH and E2 and to discuss controversies in the relationship between FSH and AMH. A better understanding of this interaction could supplement our current knowledge about the pathophysiology of the polycystic ovary syndrome (PCOS).

SEARCH METHODS

A literature review was performed using the following search terms: androgens, FSH, FSH receptor, anti-Mullerian hormone, AMHRII, estradiol, follicle, ovary, PCOS, aromatase, granulosa cell, oocyte. The time period searched was 1980-2015 and the databases interrogated were PubMed and Web of Science.

OUTCOMES

During the pre-antral ('gonadotropin-independent') follicle growth, FSH is already active and promotes follicle growth in synergy with theca cell-derived androgens. Conversely, AMH is inhibitory by counteracting FSH. We challenge the hypothesis that AMH is regulated by androgens and propose rather an indirect effect through an androgen-dependent amplification of FSH action on granulosa cells (GCs) from small growing follicles. This hypothesis implies that FSH stimulates AMH expression. During the antral ('gonadotropin-dependent') follicle growth, E2 production results from FSH-dependent activation of aromatase. Conversely, AMH is inhibitory but the decline of its expression, amplified by E2, allows full expression of aromatase, characteristic of the large antral follicles. We propose a theoretical scheme made up of two triangles that follow each other chronologically. In PCOS, pre-antral follicle growth is excessive (triangle 1) because of intrinsic androgen excess that renders GCs hypersensitive to FSH, with consequently excessive AMH expression. Antral follicle growth and differentiation are disturbed (triangle 2) because of the abnormally persisting inhibition of FSH effects by AMH that blocks aromatase. Beside anovulation, this scenario may also serve to explain the higher receptiveness to gonadotropin therapy and the increased risk of ovarian hyperstimulation syndrome (OHSS) in patients with PCOS.

WIDER IMPLICATIONS

Within GCs, the balance between FSH and AMH effects is pivotal in the shift from androgen- to oestrogen-driven follicles. Our two triangles hypothesis, based on updated data from the literature, offers a pedagogic template for the understanding of folliculogenesis in the normal and polycystic ovary. It opens new avenues for the treatment of anovulation due to PCOS.

Effect of oral administration of low-dose follicle stimulating hormone on hyperandrogenized mice as a model of polycystic ovary syndrome

Background

Polycystic Ovary Syndrome (PCOS) is a widespread reproductive disorder characterized by a disruption of follicular growth and anovulatory infertility. In women with PCOS, follicular growth and ovulation can be induced by subcutaneous injections of low doses of follicle stimulating hormone (FSH). The aim of this study was to determine the effect of oral administration of recombinant human FSH (rhFSH) on follicle development in a PCOS murine model. Moreover, since it is unlikely that intact rhFSH is present into the circulation after oral administration, the biological activity of a peptide fragment, derived from the predicted enzymatic cleavage sites with the FSH molecule, was investigated in vitro on cumulus-enclosed oocytes (COCs).

Methods

Female peripubertal mice were injected with dehydroepiandrosterone (DHEA) diluted in sesame oil for 20 consecutive days and orally treated with a saline solution of rhFSH. A control group received only sesame oil and saline solution. At the end of treatments, blood was analyzed for hormone concentrations and ovaries were processed for morphological analysis. The presumptive bioactive peptide was added during in vitro maturation of bovine COCs and the effects on cumulus expansion and on maturation rate were evaluated.

Results

DHEA treatment increased serum levels of testosterone, estradiol and progesterone as well as the percentage of cystic follicles. Orally administered rhFSH restored estradiol level and reduced the percentage of cystic follicles. Despite these results indicating a reduction of the severity of PCOS in the mouse model, the presumptive bioactive peptide did not mimic the effect of rhFSH and failed to induce bovine cumulus expansion and oocyte maturation in vitro.

Conclusions

Although further studies are needed, the present data supports the concept that orally administrated FSH could attenuate some of the characteristic of PCOS in the mouse model.

Prevalence of hyperandrogenism and polycystic ovary syndrome in female to male transsexuals

INTRODUCTION

Prevalence of hyperandrogenism (HA), including the polycystic ovary syndrome (PCOS), in female-to-male transsexuals (FMT) is high. This has been related to metabolic syndrome (MS), which appears to increase cardiovascular morbidity and mortality throughout cross-sex hormone (CSH) therapy.

OBJECTIVES

To assess the prevalence of HA and PCOS in FMT patients before the start of CSH therapy, and their association to MS and its components, insulin resistance (IR) and other cardiovascular risk (CVR) factors.

MATERIALS AND METHODS

Seventy-seven FMTs underwent clinical and biochemical assessment for HA before the start of CSH therapy. CVR, IR, and other MS parameters were also assessed.

RESULTS

Prevalence of HA was 49.4% (73.7% were cases of PCOS [Rotterdam criteria]), and prevalence of PCOS in the overall sample was 36.4%. Prevalence of MS was 38.4% and 51.7% according to ATP-III and IDF criteria respectively). MS (according to ATP-III and IDF criteria respectively) was found in 36.8% and 57.9% as compared to 25.6% and 41% of patients with and without HA respectively (p<0.0001 and P<0.01 respectively). Of total patients, 54.5% had normal weight (body mass index [BMI] 18.5-24.9 kg.m(-2)), 26% were overweight (BMI 25-29.9 kg.m(-2)), and 19.5% were obese (BMI ≥ 30 kg.m(-2)). After adjusting for BMI, the comparison of hormonal, metabolic, and anthropometric parameters showed statistically significant differences in plasma glucose, HOMA-IR, and abdominal circumference (P<0.001 for all), as well as HDL cholesterol (HDL) (P=0.033), but not in total testosterone or calculated free testosterone levels. In the total sample, 27.3% had HDL levels less than 50mg/dL.

CONCLUSIONS

Overall HA, and PCOS in particular, are highly prevalent in FMTs. HA and PCOS are related to early development of SM, IR, and other CVR factors with unknown consequences in adulthood.

Androgens and poor responders: are we ready to take the plunge into clinical therapy?

OBJECTIVE

To review and summarize data from the scientific literature on the use of androgens to improve ovarian function.

DESIGN

Review of pertinent literature.

SETTING

University hospital.

PATIENT(S)

Women exposed to androgens.

INTERVENTION(S)

None.

MAIN OUTCOME MEASURE(S)

Critical review of the literature.

RESULT(S)

The artificial increase of intra-ovarian androgen concentrations constitutes an attractive concept for improving the deficient ovarian function of poor responders. Data from studies conducted in animals treated with high-dose androgens, together with observations made in hyperandrogenic women or female-to-male transsexuals receiving virilizing androgen doses, indicate that androgens may increase follicle responsiveness to FSH and/or the number of growing follicles in the ovary. Yet, definite clinical demonstration of such a concept still is not available.

CONCLUSION(S)

Current clinical approaches aiming at increasing androgen availability in the ovary showed conflicting results. Therefore, additional studies using proper strategies to achieving higher intra-ovarian androgen concentrations for longer intervals are required to define the clinical efficiency of androgens in poor responders.

Distinctive features of female-to-male transsexualism and prevalence of gender identity disorder in Japan

INTRODUCTION

The prevalence of transsexualism is thought to differ among socio-geographic backgrounds, and little is known about its prevalence in Japan. Polycystic ovary syndrome (PCOS), which is known to be associated with insulin resistance and metabolic syndrome, is often seen in female-to-male (FTM) transsexual patients. Consequently, detection of PCOS is an important part of health care for these individuals.

AIM

The purpose of this study was to assess the prevalence of transsexuality in Japan, as well as the incidences of PCOS and insulin resistance among Japanese FTM transsexual patients.

METHODS

One hundred four male-to-female (MTF) and 238 FTM Japanese transsexual patients were studied. Medical histories, including histories of menstrual cycling and hormone treatment, were taken. To exclude other diseases, such as congenital adrenal hyperplasia and hormone-secreting tumors, thorough medical assessments, including transvaginal or transrectal ultrasonography and measurement of serum hormone levels and insulin resistance indexes, were performed.

MAIN OUTCOME MEASURES

The diagnosis of PCOS was based on the Rotterdam 2003 criteria.

RESULTS

Based on demographic statistics, the prevalences of MTF and FTM transsexuality are about 3.97 and 8.20 per 100,000 people, respectively, making the MTF-to-FTM ratio about 1:2. Of the FTM transsexual patients studied, 128 had not taken hormones before their initial assessment (untreated group); the remaining 50 self-administered androgen. Among the untreated group, 32.0% were diagnosed with PCOS, 30.1% were insulin-resistant, and 31.1% showed hypoadiponectinemia.

CONCLUSIONS

The sex ratio among Japanese transsexuals is different than among Caucasians. PCOS and insulin resistance are common findings in FTM transsexual patients at initial presentation.

Transcriptional profiling with a pathway-oriented analysis identifies dysregulated molecular phenotypes in the endometrium of patients with polycystic ovary syndrome

CONTEXT

Polycystic ovary syndrome (PCOS) is a common endocrine disorder characterized by chronic oligo/anovulation, hyperandrogenemia, infertility, and metabolic alterations related to insulin resistance. These abnormalities in PCOS may have complex effects on pathophysiology of the endometrium, contributing to infertility and endometrial disorders.

OBJECTIVE

The objective of this study was to examine dysregulated signaling pathways in the endometrium of patients with PCOS (PCOSE) by analyzing expression profiles with a pathway-oriented method.

DESIGN

Microarrays, RT-PCR, laser capture microdissection, and immunohistochemistry were performed with endometrial tissues.

SETTING

This study was performed at a university hospital laboratory.

PATIENTS

This study comprised 12 regularly cycling women and 12 PCOS patients.

MAIN OUTCOME MEASURE

Dysregulated signaling pathways in PCOSE were identified as a gene set.

RESULTS

Hierarchical clustering revealed distinct expression profiles for PCOSE and the endometrium of normal cycling women. Gene sets associated with androgen signaling were not enriched in PCOSE, although they affect ovarian physiology of PCOS patients. Several biological pathways including cell cycle, apoptosis, glycolysis, and integrin-Rho-cytoskeleton network were aberrantly down-regulated in PCOSE. Expression of genes constituting these gene sets enriched in normal cycling women was systemically down-regulated in PCOSE. Laser capture microdissection-coupled real-time RT-PCR and immunohistochemistry further demonstrated that cell proliferation in the stroma, but not the epithelium, is significantly reduced in PCOSE.

CONCLUSIONS

Systemic down-regulation of various signaling pathways in PCOSE with extremely prolonged proliferative phase provides insight into the abnormal phenotypes that reflect pathophysiology of PCOS in the endometrium, possibly leading to increased risks of endometrial disorders.

Gynecologic care of the female-to-male transgender man

Transgender men are a vulnerable population whose health care needs have been difficult to identify because of limited research and an inability to identify the population. Limited evidence suggests that transgender men are at increased risk of having polycystic ovarian syndrome, contracting HIV, experiencing violence, and committing suicide. This qualitative study, conducted through face-to-face interviews of a convenient sample, was a three-part interview containing a demographic and health questionnaire, the Norbeck Social Support Questionnaire, as well as the Health Care Relationship Trust Scale. Audio recordings and written notes were reviewed and common themes were identified via content analysis. Six self-identified transgender men between the ages of 19 and 45 years were enrolled in the study. Participants were at varying degrees of social and medical transition. Four major themes were identified: 1) receiving gynecologic care was perceived to be important; 2) breasts caused the most gender identity conflict; 3) transgender men struggle with revealing their gender identity to health care providers; and 4) the male/female boxes on health intake forms, as well as pronoun usage by medical staff, were barriers to receiving health care. This gynecologic health care needs assessment of transgender men begins to characterize the barriers transgender men face when seeking health care.

Utilization of health care among female-to-male transgender individuals in the United States

Female-To-Male (FTM) transgender individuals were approached at a conference and several peer support groups in the United States and asked to complete a short questionnaire regarding their medical care. Results from the 122 completed questionnaires indicated that a high number of respondents were taking testosterone (n = 106) and had some gender-confirming surgery (n = 68). Seventy percent of respondents rated their overall quality of health care "good" or "excellent." A surprising finding was the low number (7%) reporting diagnoses of polycystic ovarian syndrome--the incidence of which has been reported elsewhere as high as 50%. Also notable were the high levels of employment, insurance, knowledge of standards of care, and access to providers, contrasting with reports from studies involving predominantly Male-To-Female (MTF) individuals. Finally, FTM's usage of transition-related medical resources can vary, but many within this study are foregoing genital surgery.

Polycystic ovary syndrome

Polycystic ovary syndrome is a heterogeneous endocrine disorder that affects about one in 15 women worldwide. The major endocrine disruption is excessive androgen secretion or activity, and a large proportion of women also have abnormal insulin activity. Many body systems are affected in polycystic ovary syndrome, resulting in several health complications, including menstrual dysfunction, infertility, hirsutism, acne, obesity, and metabolic syndrome. Women with this disorder have an established increased risk of developing type 2 diabetes and a still debated increased risk of cardiovascular disease. The diagnostic traits of polycystic ovary syndrome are hyperandrogenism, chronic anovulation, and polycystic ovaries, after exclusion of other conditions that cause these same features. A conclusive definition of the disorder and the importance of the three diagnostic criteria relative to each other remain controversial. The cause of polycystic ovary syndrome is unknown, but studies suggest a strong genetic component that is affected by gestational environment, lifestyle factors, or both.

Persistent estrus rat models of polycystic ovary disease: an update

OBJECTIVE

To critically review published articles on polycystic ovary (PCO) disease in rat models, with a focus on delineating its pathophysiology.

DESIGN

Review of the English-language literature published from 1966 to March 2005 was performed through PubMed search. Keywords or phrases used were persistent estrus, chronic anovulation, polycystic ovary, polycystic ovary disease, and polycystic ovary syndrome. Articles were also located via bibliographies of published literature.

SETTING

University Health Sciences Center.

INTERVENTION(S)

Articles on persistent estrus and PCO in rats were selected and reviewed regarding the methods for induction of PCO disease.

MAIN OUTCOME MEASURE(S)

Changes in the reproductive cycle, ovarian morphology, hormonal parameters, and factors associated with the development of PCO disease in rat models were analyzed.

RESULT(S)

Principal methods for inducing PCO in the rat include exposure to constant light, anterior hypothalamic and amygdaloidal lesions, and the use of androgens, estrogens, antiprogestin, and mifepristone.

CONCLUSION(S)

The validated rat PCO models provide useful information on morphologic and hormonal disturbances in the pathogenesis of chronic anovulation in this condition. These studies have aimed to replicate the morphologic and hormonal characteristics observed in the human PCO syndrome. The implications of these studies to human condition are discussed.

Prevalence of polycystic ovaries and polycystic ovary syndrome in lesbian women compared with heterosexual women

OBJECTIVE

To determine the prevalence of polycystic ovaries (PCO) and polycystic ovarian syndrome (PCOS) in lesbian women compared with heterosexual women undergoing fertility treatment.

DESIGN

A prospective observational study.

SETTING

The London Women's clinic and The Hallam Medical Center. Tertiary referral fertility setup.

PATIENT(S)

Six hundred eighteen women undergoing ovarian stimulation with or without IUI treatment between November 2001 and January 2003. Of these, 254 were self-identified as lesbians and 364 were heterosexual women.

INTERVENTION(S)

Baseline pelvic ultrasound examination and blood tests conducted to measure biochemical parameters such as FSH, LH, E(2), PRL, T, androstenedione (A), sex hormone-binding globulin (SHBG), and DHEAS were performed between day 2 and 3 of each woman's menstrual cycle. Tubal patency tests were performed by hysterosalpingography or laparoscopy.

MAIN OUTCOME MEASURE(S)

Biochemical parameters.

RESULT(S)

Eighty percent of lesbian women, compared with 32% of the heterosexual women, had PCO on pelvic ultrasound examination. Thirty-eight percent of lesbian women, compared with 14% of heterosexual women, had PCOS. There were no significant differences in the androgen concentrations between lesbian and heterosexual women with normal ovaries. However, lesbian women with PCO and PCOS had significantly higher androgen concentrations compared with heterosexual women with PCO and PCOS. Tubal disease was as common in lesbian women as in heterosexual women.

CONCLUSION(S)

There is a significantly higher prevalence of PCO and PCOS in lesbian compared with heterosexual women. Lesbian women with either PCO or PCOS had more pronounced hyperandrogenism than did heterosexual women with either PCO or PCOS.

Endocrinologic treatment of gender identity disorders

OBJECTIVE

To review the diagnosis, therapeutic options, and potential complications of treatment of transsexualism.

METHODS

We summarize the appropriate initial assessment and the current guidelines for hormonal and surgical treatment of patients with transsexualism.

RESULTS

The cardinal feature of transsexualism is the permanent feeling of gender dysphoria. As part of the treatment of this condition, patients may seek medical and surgical therapies to change their physical appearance to match their internal gender identity. Cross-sex hormone therapy is a key medical management and is often prescribed in consultation with an endocrinologist. Patients should participate in a period of psychotherapy before such hormonal therapy is initiated. Medical therapies for transsexualism are associated with potentially serious complications, such as thromboembolism related to estrogen treatment and testosterone-induced hepatotoxicity. Patients should be carefully selected for therapy with use of the current management guidelines published by the Harry Benjamin International Gender Dysphoria Association.

CONCLUSION

Physicians caring for patients with transsexualism should have a general knowledge about the diagnosis, available treatment, and monitoring for complications of hormonal therapy. Ongoing research and education are necessary for improvement in the health care of these patients.

Ovarian cancer in female-to-male transsexuals: report of two cases

BACKGROUND

Ovarium cancer is the fifth most common cause of cancer-related death in women and is the most common fatal gynecologic malignancy. So far, ovarium carcinoma has not been reported to have occurred in female-to-male transsexuals.

OBJECTIVE AND METHOD

We report on two such cases. Long-term exposure to increased levels of endogenous and exogenous androgens is hypothesized to constitute an additional risk factor in transsexuals as it has been associated with ovarian epithelian cancer.

CONCLUSION

Simultaneous salpingo-oophorectomy should be performed in any female-to-male transsexual undergoing hysterectomy in the course of gender-confirming therapy.

Combined oral contraceptives and gonadotropin releasing hormone agonistic analogs in polycystic ovary syndrome: clinical and experimental studies

Polycystic ovary syndrome is a common endocrine disorder, presenting with menstrual irregularities, hirsutism, obesity, infertility and abnormal ovarian morphology. In addition, polycystic ovary syndrome is associated with a self-perpetuating imbalance involving the endocrine system and metabolic pathways, in which carbohydrates, lipids and growth factors are involved. Because of its chronicity, it is considered to be a substantial risk factor for atherogenesis and hormone-dependent neoplasia. The etiology and pathophysiology of the syndrome remain elusive. However, during the last decade, several clues have emerged from human and animal studies that may have significant repercussions in the treatment of polycystic ovary syndrome. Therapeutic maneuvers should be directed towards the dominant abnormalities present in individual patients with polycystic ovary syndrome. Gonadotropin releasing hormone (GnRH) agonists can directly affect the gonadotropin generator and secondary downstream derangements, whereas combined oral contraceptives (COCs) can modify hypothalamic as well as peripheral abnormalities. In view of the fact that GnRH agonistic analogs (GnRH-a) will induce hypoestrogenemia and its sequelae, the add-back strategy of estrogenic supplementation is recommended for preventive reasons and, as it transpires from some studies, for enhancement of GnRH-a effectiveness.

A higher rate of hyperandrogenic disorders in female-to-male transsexuals

In an effort to elucidate the aetiology of female-to-male transsexualism (FM-TS) 12 out of an annual sample of 16 untreated female-to-male transsexuals (FMT), aged 19 years 7 months (19;7) to 44 years 8 months (44;8) [median age (M) 27;5] were assessed by means of sexual-medical questionnaires, physical and endocrinological examination. The control group consisted of 15 healthy women (CF), aged 19 years 2 months (19;2) to 36 years 1 month (36;1) (M 22;7) without gender identity disorder, who were not under hormonal medication (including contraceptives). Baseline levels of testosterone (T; ng/dl), androstenedione (A4; ng/dl), dehydroepiandrosterone sulfate (DHEAS; ng/ml), luteinizing hormone (LH; IU/l), follicle stimulating hormone (FSH; IU/l), and sex-hormone binding globuline (SHBG; microgram/dl) were measured. A standard single-dose ACTH stimulation test (250 micrograms ACTH IV; Synacthen) was performed with all subjects. Aldosterone (ALDO), corticosterone (B), deoxycorticosterone (DOC), progesterone (PROG), 17-hydroxyprogesterone (17OHP), 11-deoxycortisol (S), cortisol (F), cortisone (E), pregnenolone (PREG) and 17-hydroxypregnenolone (OHPREG) were assessed before and 60 min after ACTH stimulation. Transvaginal ultrasound was performed in nine out of 12 FMT (20;11 to 44;8, M 27;5; m 29.1 +/- 7.5) but not in CF. Results showed that 10 FMT (83.3%) and five CF (33.3%) were above normal values for at least one of the measured androgens. Baseline levels of T and A4 were significantly higher in FMT than in CF (T: 54.0 +/- 13.8 vs. 41.1 +/- 12.8; A4: 244.8 +/- 73.0 vs. 190.5 +/- 49.3; p < .05), whereas DHEAS, SHBG, LH and FSH did not differ between the groups. Unbound T (T/SHBG ratio) was higher in FMT (72.0 +/- 67.6) than in CF (26.4 +/- 15.1). Baseline levels of 17OHP, OHPREG and DOC were higher in FMT than in CF (p < .05). After ACTH stimulation 17OHP and OHPREG remained higher in FMT than in CF (p < .05). Single case analysis of ACTH stimulation test together with physical examination revealed symptoms for non-classical congenital adrenal hyperplasia (NC-CAH) in six FMT (50%) and two CF (13.3%). Eight out of nine FMT who were assessed by means of transvaginal ultrasound (i.e. 88.9%; 50.0% of 16) had polycystic ovaries (PCO). Oligomenorrhoea or menstrual dysregularities (81.7% of 16 FMT vs. 0% of CF), hirsutism (56.2% of 16 FMT vs. 13.3% of 15 CF) and adiposity (25.0% vs. 0%) were frequent in FMT, but not in CF. Hyperandrogenism with polycystic ovarian syndrome (PCOS) and adrenocortical hyperresponsiveness to ACTH seems to be a common finding in FMT. This offers support for a hormonal factor in the genesis of FM-TS. Because the prevalence of PCOS and NC-CAH in the female population is higher than FM-TS, the true nature of this factor and its interaction with environmental influences remains unknown.

Ovulation and the polycystic ovary syndrome

In the 1930s, Stein and Leventhal added amenorrhoea to anovulatory dysfunctional uterine bleeding among the known clinical manifestations of the polycystic ovary syndrome (PCOS). Whatever the menstrual pattern, infrequent or absent ovulation with symmetrical enlargement of the ovaries is now a familiar abnormality in women of reproductive age. Diagnosis of PCOS has developed from just the clinically obvious to an appreciation, through ultrasound imaging of the ovaries and endocrine testing, of its subtler forms. Today's clinicians will identify PCOS on the ultrasound image of many small follicles apparent in the periphery of both ovaries, on raised serum unbound testosterone assays, on exaggeration of serum LH levels with the start of pulsatile GnRH therapy, and on follicular overresponsiveness to injections of FSH. Once among the most treatable causes of infertility, ovulation-induction for PCOS remained unsophisticated while microsurgery and assisted conception dissolved frontiers for other causes of infertility. Whereas we now have the benefit of high technology embryo cryostorage to cope with embarrassingly high yields of PCOS oocytes, we still need to explain why, the bigger the ovaries, the more likely (we have long known it to be) that PCOS can be cured simply by reducing ovarian mass. Some cases of PCOS are hereditary and most seem constitutionally determined. PCOS is so common that the questions must be asked, Are we appreciating an extreme of normal? Could the milder forms of PCOS have--or could PCOS have had--evolutionary usefulness?

“You Think You’re the Only One”: Comparing Descriptions and Lived Experiences of Polycystic Ovarian Syndrome

This article examines the biomedical diagnosis of polycystic ovarian syndrome (PCOS) from the perspectives of medical anthropology and science and technology studies (STS), addressing two main questions: what does a historical, medical anthropology and STS perspective reveal about how PCOS is described and understood in contemporary North America, and what are the lived experiences of people with this diagnosis? Common descriptions of PCOS are based in normative gendered assumptions. Drawing on interviews with people diagnosed with PCOS and on analysis of historical and contemporary biomedical literature discussing PCOS, I argue that the lived experiences of people with PCOS vary significantly from mainstream (biomedical and popular) descriptions of the diagnosis.
