impact of cryopreservation process on viability, nitric oxide and dna apoptosis in fertile human spermatozoa

Impact of Cryopreservation Process on Viability, Nitric Oxide and DNA Apoptosis in Fertile Human Spermatozoa

Introduction: Infertility is a common phenomenon in modern societies. Today, use of assisted reproductive technologies (ARTs) for treatment of infertility is common, and cryopreservation is one of these technologies. Cryopreservation has impact on the function and percentage of fertility of human sperm. In this study, motility, viability, nitric oxide, and DNA apoptosis were assessed before and...

nerve growth factor in human semen: effect of nerve growth factor on the normozoospermic men during cryopreservation process

objective(s):althoughroutinely applied in assisted reproductive technology, human sperm cryopreservation is not a completely successful procedure. adverse effects of cryopreservation on the fertilization capacity, motility, morphology, and viability of spermatozoa have been proven; cryopreservation has also shown a role in sperm dna fragmentation and infertility. the post-thaw survival of sperm...
