Abstract:
The purpose of this article is to analyze in detail the advantages and disadvantages of sperm cryopreservation, focusing on the cellular and molecular changes that occur during these processes. The main issue is the cellular damage caused by ice crystal formation and osmotic imbalance, along with other secondary effects such as sperm motility and viability, as well as the acrosome reaction or oxidative stress. Another important aspect is the examination of how chromatin structure and DNA integrity affect sperm. Biochemical changes affecting enzyme activity and protein stability have also been analyzed. Finally, the article highlights emerging technologies aimed at reducing the damage caused by sperm cryopreservation, as well as the potential benefits of biobanks as an essential resource for addressing male infertility.
