Fertility preservation of sperm (cryopreservation) is done in an effort to ensure a man’s options for fathering a child in the future. Sperm freezing is often performed prior to treatments for cancer and other diseases and also, prior to deployment into combat.
Semen samples can be obtained via masturbation in males of post-adolescent age and up, or via other techniques, such as testicular sperm extraction (TESE), percutaneous sperm aspiration (PESA) or testicular spermaspiration (TESA).
Once procured, the semen will undergo a washing procedure to eliminate debris, such as dead cells and to separate out the sperm from the seminal fluid. Frozen sperm can then be batched into individual vials which can be thawed one at a time and stored for an indefinite period of time.
