Sperm cryopreservation is a method to preserve sperm samples for a long period. However, the fertility of sperm decreases markedly after freezing and thawing in a certain amount of samples. The aim of the present study was to find useful and reliable predictive biomarkers of the capacity to withstand the freeze-thawing process in human ejaculates. Previous(More)
