The purpose of the present investigation was to measure the concentration of progesterone (P4), androgens (A) and estradiol (E2) in follicular wall of the three largest posovulatory follicles. The major findings in the present study are: 1) the postovulatory follicles of the goose, which are not homologous with the mammalian corpus luteum, are an active endocrine tissue; 2) follicular wall of postovulatory follicles can synthesize large amounts of progesterone and lesser amounts of androgens and estradiol. This study also suggest that the steroidogenic potential of the follicular cells was markendly reduced during the process of follicular regression.
