Ovarian hyperthecosis is another condition related to PCOS that most often presents in the perimenopausal period. This condition accounts for less than 1% of women with elevated androgens in their reproductive years, but most of the cases of hyperandrogenemia in postmenopausal women. [49]

Ovarian hyperthecosis is described when luteinized theca cell nests are present in the ovarian stroma. Although there is a considerable overlap between hyperthecosis and PCOS, hyperthecosis is associated with a more severe form of hyperandrogenism and virilization. Testosterone levels are much higher than PCOS and may reach levels greater than 200 ng/dL. [50]
