Motility and Morphology of Human Sperms after Feezing in Liquid Nitrogenfreezing, the viability after freezing and thawing will be better. Many different substances have been used as protective agents. In this investigation the effect of glycerol and glycerol-egg-yolk-citrate on sperm freezing has been studied.
