Aim: To investigate whether early apoptotic changes in spermatozoa can be significant markers for sperm quality. Methods: Two early apoptotic changes in the semen of 56 men were assessed using Annexin V (AN)/propi...
Aim: To estimate the dissipation of mitochondrial transmembrane potential (mTMR,Δψ_m) and activation of sperm caspases (aCP) as signs of apoptosis in human spermatozoa during cryopreservation and to evaluate the eff...
