[Detection of apoptotic markers in human ejaculated spermatozoa as new methods in human reproductive biology]

Ejaculated spermatozoa, particularly in infertile men, have been shown to display numerous features that are typical of apoptosis in somatic cells including Fas expression, ROS production, activation of caspases, DNA fragmentation, reduction in mitochondrial membrane potential, plasma membrane translocation of phosphatidylserine and permeability. In this review we summarize the biological significance and the potential role of these markers in the exploration of men infertility.
