Abstract
IT has been shown that progesterone1 and certain related steroid compounds such as testosterone, methyltestosterone, androstenedione2 and 11-deoxycorticosterone3 will cause ovulation when injected into Xenopus laevis. Ovulation was induced also in the excised ovary suspended in frog's Ringer solution by the addition of progesterone1, testosterone and androstenedione4.
