Polycystic Ovary Syndrome and Gender Identity.

Polycystic Ovary Syndrome and Gender Identity. Yale J Biol Med. 2020 Sep;93(4):529-537 Authors: Liu M, Murthi S, Poretsky L Abstract Polycystic ovary syndrome (PCOS) is a common endocrinopathy affecting 46XX individuals of reproductive age. Cardinal features of PCOS include hyperandrogenism, irregular periods, and insulin resistance. Pathogenesis is unclear but likely involves hypothalamic, pituitary, or ovarian abnormalities leading to increased androgen production. In addition, alternative insulin signaling pathways are activated to preserve ovarian sensitivity to insulin while other "classical" tissues (e.g. liver, adipose, muscle) are insulin resistant. Treatment targets specific symptoms and the most common regimens include weight loss, metformin, oral contraceptives, anti-androgen compounds, and fertility treatments. Observations of individuals with gene mutations affecting androgen metabolism suggest that androgens may influence the development of gender identity. We reviewed studies exploring the relationship between gender identity and PCOS to further elucidate this relationship. Rates of PCOS in hormone-naïve transmasculine (TM) individuals appear to be higher than in the general population as cited by small, early studies using convenience samples and inconsistent criteria for PCOS. A more recent, larger study using established guidelines for PCOS did not show this to be true. Further, other studies show that although PCO...
