Species difference in the expression of Fas and Fas ligand in mature mammalian spermatozoa
Czech Journal of Animal Science, 2017 Although it has been proposed that the Fas and Fas ligand (FasL) may protect ejaculated spermatozoa against apoptosis induced by lipoperoxidative damage and against lymphocytes present in the female genital tract, studies reported conflicting results on ...

Calcium-induced asymmetrical beating of triton-demembranated sea urchin sperm flagella [PDF]
, 1979 Asymmetrical bending waves can be obtained by reactivating demembranated sea urchin spermatozoa at high Ca2+ concentrations. Moving-film flash photography shows that asymmetrical flagellar bending waves are associated with premature termination of the ...
