Abstract:

Capacitation is a crucial stage before sperm and egg cell complete fertilization in mammals. A series of physiological and biochemical processes are altered in accompany with sperm capacitation, including ion content changes, plasma membrane remodeling, cholesterol efflux, and protein tyrosine phosphorylation. In addition, decapacitation factors enable sperms to successfully complete fertilization. These alternations can be used to detect sperm capacitation status. The commonly used methods include the detections of sAC-cAMP-PKA pathway, plasma membrane fluidity change, cholesterol redistribution, tyrosine phosphorylation, and acrosome reaction. This article reviews the research progress in signaling pathways, signaling molecules, regulatory factors, ion channels, and sperm capacitation detection methods involved in sperm capacitation in mammals, and prospected the main research directions in the future, in hoping to provide references for sperm in vitro culture and the application of assisted reproductive technology.

Key words: sperm capacitation, decapacitation factor, signaling pathway, detection method
