Sperm can be cryogenically stored for many years while remaining viable, with successful use reported after storage periods of 10 years or more. In optimal conditions, some studies suggest that sperm can remain viable for up to 20 years or even longer. The key factors affecting viability include the freezing technique, storage temperature, and handling procedures. Regular monitoring and proper storage practices are essential to ensure the sperm's quality over time.
