Abstract:
Human sperm cryopreservation is an effective approach to the management and preservation of male fertility, and sperm quality after cryo-resuscitation is an important factor influencing the clinical outcomes of assisted reproductive technology. Either donor or autologous sperm cryopreservation is subjected to the impact of cryoinjury on semen quality. Studies show that oxidative stress has a negative impact on sperm function during sperm freezing and thawing, and antioxidants, as compounds to treat, scavenge, inhibit, or impede oxidative chain reaction that forms reactive oxygen species or counteracts their effects, can protect sperm cells from oxidative stress and are essential for sperm function. This review describes the mechanism of oxidative stress in sperm freezing and thawing, presents an overview of the advances in the studies of various commonly used antioxidants in cryopreservation of human sperm, and provides some reference for further research on the effects of antioxidants and their clinical application.
