[Gonadotropic function in female Cushing syndrome (author's transl)]

A study of 38 female Cushing syndromes showed decreased levels of FSH and LH, with normal LH-RH stimulation in most adrenal hyperplasia and benign adenoma, and absent stimulation in carcinoma. The levels were normalized by suppression of hypercorticism. This suggests a blunted gonadotropic function, in female Cushing syndrome, probably at the hypothalamic level. The predominant respective roles of hyperandrogeny in carcinoma and of hypercortisolism in adrenal hyperplasia and benign adenoma seem probable.
