Male fertility preservation receives growing attention in the field of reproductive medicine. The first clinical programs were established to preserve reproductive potential in men needing gonadotoxic treatment. Sperm cryopreservation is now a standard procedure. Since a few years, several centres offer testicular tissue cryopreservation to prepubertal boys. This method is still experimental and further research is needed to implement the transplantation techniques in the clinic. With the aim to preserve or restore fertility in patients affected by other diseases (Klinefelter syndrome, Sertoli cell only syndrome), techniques for in vitro spermatogenesis are being developed.
