Regulation and disruption of hamster sperm hyperactivation by progesterone 17β‐estradiol and diethylstilbestrol

摘要

PurposeHyperactivation of hamster sperm is dose‐dependently enhanced by progesterone (P) and 17β‐estradiol (E). In the first part of the present study, enhancement of hyperactivation in response to the concentrations of P and E was examined in detail and in the second part, it was examined whether enhancement of hyperactivation by P and E was disrupted by diethylstilbestrol (DES).
