Co‐Expression of Mannose‐Ligand and Non‐Nuclear Progesterone Receptors on Motile Human Sperm Identifies an Acrosome‐Reaction Inducible Subpopulation

Abstract

Sperm from fertile donors incubated under capacitating conditions in vitro can be subdivided into acrosome reaction inducible and noninducible subpopulations on the basis of the co-expression or total absence of these receptors. The combined data indicate that reaction of sperm surface progesterone receptors with ASAs contributes to the acrosome reaction insufficiency observed in anti-sperm immune infertility.
