          In order to determine whether the ovarian follicles of the domestic cat which normally ovulates following copulation, were similar to those of the rabbit steroidogenically, the following experiments were carried out. Follicles were dissected out of ovaries from nine estrous cats throughout the year and incubated in medium alone or with luteinizing hormone (LH) or human chorionic gonadotropin (HCG). Media were removed every 15 min and stored frozen until analyzed for testosterone using established radioimmunoassay procedures. Although LH and HCG caused slight increases in testosterone production the amounts produced were much less than that produced by rabbit follicles under identical conditions. However, when follicles were incubated for a total of 8 h without removal of media, marked changes in testosterone and estradiol production occurred. These data suggest that the ovarian follicles of the estrous cat are steroidogenically active.
