Caspase-3 activation and phosphatidylserine membrane translocation in human spermatozoa: is there a relationship?

Abstract The presence of biochemical signs of apoptosis in ejaculated spermatozoa suggests that apoptosis may be one of the pathways for sperm death. The relationship between the phosphatidylserine (PS) externalization and the presence of the active form of caspase-3 (CP-3) was studied in human sper...
