A sperm bank is a facility that collects, freezes, and stores human semen for future use. The semen is produced and sold by men known as sperm donors, and it is purchased by or for other persons for the purpose of achieving a pregnancy or pregnancies other than by a sexual partner. Sperm banks provide the opportunity for individuals to have a child who otherwise would not be able to conceive naturally, including single women, same-sex couples, and couples where one partner is infertile.

Sperm banking is a process that collects, freezes, and stores sperm cells in a special healthcare facility. The most common reason for sperm banking is if a person needs treatment for cancer, as chemotherapy or radiation therapy can leave very few or no sperm left in the ejaculate. Other reasons for sperm banking include age, as sperm quality diminishes with age, and infertility, where a very low sperm count or no sperm in the semen may require surgery to extract sperm.

Sperm banks take a number of steps to ensure the health and quality of the sperm they supply, and they will inform customers of the checks they undertake, providing relevant information about individual donors. They will usually guarantee the quality and number of motile sperm available in a sample after thawing. Sperm banks do not provide a cure for infertility in individuals who produce non-viable sperm, but they offer an opportunity for individuals to have biological children in the future.

In summary, a sperm bank is a facility that collects, freezes, and stores human semen for future use, providing an opportunity for individuals to have a child who otherwise would not be able to conceive naturally. Sperm banking is a safe and effective way to maintain fertility for years, and it is commonly used by individuals who need treatment for cancer or who have infertility issues.
