Many of the same signs and symptoms that are seen in women, such as alopecia and acne, may also be found in men. Enlargement of the prostate may also occur. Causes
While hyperandrogenism in women can be caused by external factors, it can also appear spontaneously. Polycystic ovary syndrome
Polycystic ovary syndrome (PCOS) is an endocrine disorder characterized by an excess of androgens produced by the ovaries. It is estimated that approximately 90% of women with PCOS demonstrate hypersecretion of these hormones. The cause of this condition is unknown. Speculations include genetic predisposition; however, the gene or genes responsible for this remain unidentified. The condition may have a hereditary basis. Other possible causes include elevated insulin production. Most cases of PCOS involve insulin resistance. It is thought that adipose tissue dysfunction plays a role in the insulin resistance seen in PCOS. Insulin can induce excess testosterone secretion from the ovaries. A complication associated with polycystic ovary syndrome is high cholesterol, which is treated with statins. In a meta-analysis, atorvastatin was shown to decrease androgen concentrations in people with hyperandrogenism.Elevated insulin leads to lower production of sex hormone binding globulin (SHBG), a regulatory glycoprotein that suppresses the function of androgens. High blood levels of insulin also work in conjunction with ovarian sensitivity to insulin to cause hyperandrogenemia, the primary symptom of PCOS. Obese individuals may be more biologically inclined to PCOS due to markedly higher insulin. This hormonal imbalance can lead to chronic anovulation, in which the ovaries fail to release mature eggs.
These regulations replaced the earlier sex verification rules.Following a series of legal challenges, regulations called the Eligibility Regulations for the Female Classification (Athletes with Differences of Sexual Development) were released on 1 May 2019. These regulations apply only to athletes who have a DSD, high testosterone and virilization, and no longer include hyperandrogenism from non-DSD-related causes such as PCOS. Such DSDs, often seen in people who have a Y chromosome and testes, include 5α‐reductase deficiency, partial androgen insensitivity, and congenital adrenal hyperplasia. Social definition
Cultural variation can define hyperandrogenism socially—apart from clinical and chemical definitions—to make some hair growth unacceptable even if it is considered clinically normal based on metrics like the Ferriman-Gallwey score. For example, only pubic and axillary hair may be tolerated in North American women, while other androgen-dependent hair such as growth on the upper lip, over the linea alba, on the thighs, and around the areola is not. Organizations
Professional organizations such as the Androgen Excess and PCOS Society exist to promote the research, treatment, diagnosis, and prevention of such disorders and to educate the public and scientific community about them. See also
