A. Vidalpuig et al., REDUCTION OF ENDOGENOUS, OVARIAN AND ADRENAL ANDROGENS WITH KETOCONAZOLE DOES NOT ALTER INSULIN-RESPONSE IN THE POLYCYSTIC-OVARY-SYNDROME, Journal of endocrinological investigation, 17(8), 1994, pp. 647-652
Several different strategies were used to investigate the relationship
between hyperandrogenism and hyperinsulinemia associated with polycys
tic ovary syndrome. Ketoconazole was given orally (400 mg/day) for 9 m
onths to evaluate the effect of reduction in ovarian and adrenal andro
gens on insulin response (oral glucose tolerance test) in 35 women wit
h polycystic ovary syndrome. Androgenic steroids (testosterone, andros
tenedione, dehydroepiandrosterone sulphate, and free testosterone inde
x) decreased (p<0.01), but basal insulinemia, maximum peak insulin, an
d insulin/glucose ratio showed no significant changes. One month after
treatment was stopped, free testosterone index, and serum concentrati
ons of androstenedione and testosterone, increased (p<0.05), but no al
terations were noted in insulin parameters. Body mass index was stable
throughout the ten-month study period. Our findings suggest that endo
genous androgens, no matter whether they are of ovarian or adrenal ori
gin, do not play a major role in the modulation of hyperinsulinemia in
patients with polycystic ovary syndrome.
