Concentration-dependent effects of in vitro gonadotropin (hCG) treatment on ovarian 17,20β-P binding to mPR. Ovarian fragments were incubated with 0, 1, 7, or 14 IU hCG for 20 hours. Each bar represents the mean ± SEM of triplicate determinations. Significant difference at the p < 0.01 level compared to control (a) and the 7 IU group (b) are indicated in the figure.
