About this trial
Freezing testicular tissue of prepubertal boys is a method for preserving spermatogonial stem cells in case of imminent gonadotoxic treatment during childhood. In case of total azoospermia or absence of spermatozoa that can be used for intra-cytoplasmic injection (ICSI) in adulthood, the investigators intend to perform the first in men autologous testicular tissue transplantation to restore fertility.
