Sperm donation is a voluntary, supportive, and altruistic act that benefits men who cannot have children. A man who chooses to donate sperm must be healthy and have good sperm quality.

Treatments using sperm donation are applicable in the following cases:

• Absence of sperm (azoospermia) in both ejaculate and testicular biopsy (procedure performed under local anesthesia).

• When a man is a carrier of a sexually transmitted disease and it is not possible to eliminate the virus from the semen.

• Repeated failures in assisted reproduction

• Women who choose to pursue independent female production.

• Female same-sex couple.

The sperm donation process only occurs through a sperm bank. Neo Vita uses both national and international sperm banks. The donor undergoes a series of tests, and after approval, the material is stored in liquid nitrogen in the laboratory. The recipient can choose a sample from the sperm bank according to their phenotypic (physical) characteristics and blood type. According to the regulations established by the Federal Council of Medicine (CFM), the recipient and donor should not know each other; this prevents any contact during treatment and after the baby's birth.
