metabolites of progesterone are its 20$-hydroxy derivatives. Data on their biological activity in vivo and in vitro, according to binding with specific receptor proteins, indicate a reduced progestagenic activity [8] and low relative affinity [6]. There are also reports that the 20=and 208hydroxyprogesterones inhibit the synthesis of progesteronein the human placenta preparations [I0]. However, 17~-et
