Correlation of biochemical markers and clinical signs of hyperandrogenism in women with polycystic ovary syndrome (PCOS) and women with non-classic congenital adrenal hyperplasia (NCAH).

Background: Polycystic ovary syndrome (PCOS) is the most common cause of hyperandrogenism in women. Non-classic congenital adrenal hyperplasia (NCAH) is very close to PCOS. The diagnosis of hyperandrogenism is not based on the finding of decreased or increased levels of a single hormone.
