REDUCTION OF GRANULOSA CELL PROGESTERONE SECRETIONIN VITROBY INTRAOVARIAN IMPLANTS OF ANTIANDROGEN

Abstract
Intraovarian Silastic implants containing the antiandrogen, flutamide, or its active metabolite [SCH 16423; .alpha., .alpha., .alpha.-trifluoro-2-methyl-4''-nitro-m-lactotoluidide], reduced the level of progesterone secretion in porcine granulosa cell cultures by approximately 50%. These results complement recent observations in vitro suggesting a role for androgen in granulosa cell steroidogenesis during follicular development.
