Preservation of the male germ line in prepubertal boys undergoing gonadotoxic treatment is a crucial consideration in terms of their future quality of life. As these patients do not yet produce spermatozoa for freezing, only immature tissue is available for storage. We studied the survival, proliferation and differentiation capacity of spermatogonia after cryopreservation and long-term transplantation of immature testicular tissue pieces.
