How is hyperandrogenism related to polycystic ovary syndrome?
(Modified from Ehrmann D, Barnes R, Rosenfield R: Polycystic ovary syndrome as a form of functional ovarian hyperandrogenism, Endocr Rev 16:322–353, 1995.) Androgens are obligate intermediates in the biosynthesis of estradiol (see Fig. 132-3) and appear to have a dual role in follicular development within the ovary.
How is Cushing’s syndrome related to hyperandrogenism?
Cushing’s syndrome has been shown to cause androgen excess, which directly links it to the signs and symptoms seen in hyperandrogenism. Congenital adrenal hyperplasia describes a group of autosomal recessive disorders that cause a lack of an enzyme needed for producing cortisol and/or aldosterone, both of which are steroid hormones.
