Decreased Responsiveness to Progesterone of Spermatozoa in Oligozoospermic Patients

2 Jan 1993

Abstract excerpt

Spermatozoa from oligozoospermic subjects are characterized by a reduced in vitro ability to penetrate hamster oocytes and by a decreased responsiveness to physiological stimuli that trigger the acrosome reaction. One of the first steps in the induction of the acrosome reaction is an increase of intracellular free calcium concentrations ([Ca2+]i). It has been recently shown that progesterone (P) is able to...
