There are a number of reasons to consider sperm cryopreservation (freezing). Some couples find it more convenient to have a sample of the man’s sperm frozen in advance of the ART treatment, particularly if they anticipate collection difficulties. Sperm freezing is also useful for men whose occupations either require them to travel extensively, or exposes them to an environment that potentially affects sperm viability.

Men about to undergo a vasectomy or a medical treatment that is expected to make them sterile (such as some forms of cancer treatment), can freeze their sperm prior to starting medical treatment or therapy, with the intention of using it to achieve a pregnancy with their partner in the future.
