Why freeze sperm?
A. Fresh semen is unsuitable for sperm banking because it begins losing its fertility within an hour or two after ejaculation. Since a sperm bank is expected to have available at all times semen from a diversity of donors with different physical characteristics and different talents, it is necessary to bank or store the sperm from the time of collection until the time of need. Xytex accomplishes this by extending the survival period to years through a special freezing process of cryopreservation. It is the only way sperm can be shipped from the bank to a distant user. Also of great importance, sperm is cryopreserved to allow testing for sexually transmitted infections, such as HIV. After being thawed, cryopreserved sperm can be just as fertile as “fresh” sperm.
