The effect of prolonged incubation and temperature on oocyte activator phospholipase C-zeta activity of sperm

Abstract

Objective: Fertilization capacity of capacitated sperm decreases exponentially over time, but the reason is still under investigation. The aim of the study was to analyze the effect of prolonged incubation and temperature on sperm fertilization capacity with motility and staining parameters of phospholipase C-zeta (PLCZ), which is considered to be the oocyte activation factor.
