Stein and Leventhal first described PCOS as an endocrine disorder in the United States, and since then, it has become recognized as one of the most common causes of oligo ovulatory infertility among women.The earliest published description of a person with what is now recognized as PCOS was in 1721 in Italy. Cyst-related changes to the ovaries were described in 1844. Etymology
Other names for this syndrome include polycystic ovarian syndrome, polycystic ovary disease, functional ovarian hyperandrogenism, ovarian hyperthecosis, sclerocystic ovary syndrome, and Stein–Leventhal syndrome. The eponymous last option is the original name; it is now used, if at all, only for the subset of women with all the symptoms of amenorrhea with infertility, hirsutism, and enlarged polycystic ovaries.Most common names for this disease derive from a typical finding on medical images, called a polycystic ovary. A polycystic ovary has an abnormally large number of developing eggs visible near its surface, looking like many small cysts. Society and culture
In 2005, 4 million cases of PCOS were reported in the US, costing $4.36 billion in healthcare costs. In 2016 out of the National Institute Healths research budget of $32.3 billion for that year, 0.1% was spent on PCOS research. Among those aged between 14 and 44, PCOS is conservatively estimated to cost $4.37 billion per year.As opposed to women in the general population, women with PCOS experience higher rates of depression and anxiety. International guidelines and Indian guidelines suggest psychosocial factors should be considered in women with PCOS, as well as screenings for depression and anxiety.
In any case, androgens, such as testosterone, androstanolone (dihydrotestosterone), and nandrolone decanoate have been found to increase visceral fat deposition in both female animals and women.Although 80% of PCOS presents in women with obesity, 20% of women diagnosed with the disease are non-obese or "lean" women. However, obese women that have PCOS have a higher risk of adverse outcomes, such as hypertension, insulin resistance, metabolic syndrome, and endometrial hyperplasia.Even though most women with PCOS are overweight or obese, it is important to acknowledge that non-overweight women can also be diagnosed with PCOS. Up to 30% of women diagnosed with PCOS maintain a normal weight before and after diagnosis. "Lean" women still face the various symptoms of PCOS with the added challenges of having their symptoms properly addressed and recognized. Lean women often go undiagnosed for years, and usually are diagnosed after struggles to conceive. Lean women are likely to have a missed diagnosis of diabetes and cardiovascular disease. These women also have an increased risk of developing insulin resistance, despite not being overweight. Lean women are often taken less seriously with their diagnosis of PCOS, and also face challenges finding appropriate treatment options. This is because most treatment options are limited to approaches of losing weight and healthy dieting.Testosterone levels are usually elevated in women with PCOS.
