In a 2020 systematic review and meta-analysis of sexual dysfunction related to PCOS which included 5,366 women with PCOS from 21 studies, testosterone levels were analyzed and were found to be 2.34 nmol/L (67 ng/dL) in women with PCOS and 1.57 nmol/L (45 ng/dL) in women without PCOS. In a 1995 study of 1,741 women with PCOS, mean testosterone levels were 2.6 (1.1–4.8) nmol/L (75 (32–140) ng/dL). In a 1998 study which reviewed many studies and subjected them to meta-analysis, testosterone levels in women with PCOS were 62 to 71 ng/dL (2.2–2.5 nmol/L) and testosterone levels in women without PCOS were about 32 ng/dL (1.1 nmol/L). In a 2010 study of 596 women with PCOS which used liquid chromatography–mass spectrometry (LC–MS) to quantify testosterone, median levels of testosterone were 41 and 47 ng/dL (with 25th–75th percentiles of 34–65 ng/dL and 27–58 ng/dL and ranges of 12–184 ng/dL and 1–205 ng/dL) via two different labs. If testosterone levels are above 140 to 200 ng/dL (per different sources), other possible causes of hyperandrogenism such as congenital adrenal hyperplasia or an androgen-secreting tumor may be present and should be excluded. Associated conditions
Many individuals arent under the impression that the first warning sign is usually a change in appearance.
Ophiasis is a form of alopecia areata characterized by the loss of hair in the shape of a wave at the circumference of the head.It gets its name from Greek ὄφις ophis snake because of the apparent similarity to a snake-shape and the pattern of hair loss.The term "sisaipho" is used to characterize the inverse pattern. Sisaipho is, almost, the reverse spelling of ophiasis. It is also called "ophiasis inversus".This form of hair loss "...targets the bodys own hair follicles, resulting in hair loss..." and although the immune system could be attacking hair follicle melanocytes, dermal papilla cells, and keratinocytes,” the foundational cause of this disease is yet to be confirmed. Pattern of hair loss
This is one among many types of patterns of hair loss, “in which they have band-link hair loss across the occiput.” Hair loss can take the form of patches of hair being removed and there can also be spontaneous regrowth as well. Duration of hair loss
Ophiasis hair loss is one form in which the hair loss can further deteriorate and can extend “for more than a year.”
