Sperm freezing is ideal for men who want to delay parenthood until a later stage in life or for men who plan to undergo certain types of medical treatments that could impact their sperm quality. Sperm may also be frozen as a backup during their fertility treatment.

Semen is collected through ejaculation or surgically assisted retrieval like TESA or TESE, it is then analysed and the sperm cells are frozen. These frozen sperm samples can be stored in the laboratory for later use in an Intrauterine Insemination (IUI) or In-Vitro Fertilisation (IVF).
