OBJECTIVE: The prevalence of androgen excess (AE) and the value of preemptive endocrine evaluation in women with minimal unwanted hair growth are unclear. SUBJECTS: A total of 228 patients presented with minimal unwanted hair growth and a mF-G score of 5 or less. Total and free testosterone, dehydroepiandrosterone sulfate, 17-hydroxy-progesterone, sex hormone-binding globulin, and basal insulin and glucose levels were measured. RESULTS: Of the patients, 54% demonstrated an AE disorder (50%: polycystic ovary syndrome, 2%: hyperandrogenic insulin-resistant acanthosis nigricans syndrome, 2%: nonclassic adrenal hyperplasia), 29% isolated oligoovulation, 6% isolated hyperandrogenemia, and 10% had a normal evaluation. Of the patients with menstrual irregularities, 65% had an underlying AE disorder compared with 22% of those with normal menstrual function ( P < .001). Of eumenorrheic patients, 11% had oligo-ovulation and an AE disorder. CONCLUSION: Patients with minimal unwanted hair growth should be evaluated endocrinologically because approximately 50% of subjects demonstrate an AE disorder. Eumenorrhea does not preclude an underlying AE disorder, and ovulatory function should be assessed in these women.
