Cryopreservation of sperm is the process of freezing and storing sperm at extremely low temperatures to preserve them for future use in assisted reproductive technologies (ART) such as in vitro fertilization (IVF) or intrauterine insemination (IUI). This technique is commonly used by men who wish to preserve their fertility before undergoing medical treatments that could impair sperm production, such as chemotherapy, radiation, or surgery for cancer. It is also utilized by men who face occupational hazards, have low sperm counts, or want to delay fatherhood for personal or professional reasons. The process begins with the collection of sperm through ejaculation, which is then analyzed and mixed with a cryoprotectant to protect the sperm cells during the freezing process. The sperm is then gradually frozen or vitrified and stored in liquid nitrogen at temperatures around -196°C. Cryopreserved sperm can remain viable for many years, and when thawed, the sperm can be used to fertilize an egg through ART methods. While sperm cryopreservation is generally successful, not all sperm cells survive the freezing and thawing process. This reduction in motility and viability can impact the success rates of subsequent fertility treatments. Additionally, there is a risk of contamination or misidentification during storage, although stringent protocols are in place to minimize such risks. Ethical considerations may also arise concerning the long-term storage of sperm, including decisions about its use in the event of the donor's death. Despite these challenges, sperm cryopreservation is a valuable option for preserving fertility, offering men the opportunity to father biological children at a later time.
