Effect of growth hormone (GH; 100 ng/mL), insulin-like growth factor I (IGF-I; 30 ng/mL), and their combination on (A) E2 and (B) P synthesis by human luteinized granulosa cells after 24 and 72 hours of culture. Data are in mean ± SEM. Each column shows results of 20 cultures from 20 different women.

Estradiol (A,C,E) and P (B,D,F) production by human luteinized granulosa cells after 24 and 72 hours of culture with GH (growth hormone), IGF-I (insulin-like growth factor-I), or GH+IGF-I in the absence or the presence of leptin at the doses of 1, 10, and 100 ng/mL. Data are in mean ± SEM. Each column shows results of 20 cultures from 20 different women.
