Effects of vitamin A on in vitro maturation of pre-pubertal mouse spermatogonial stem cells.

Testicular tissue cryopreservation is the only potential option for fertility preservation in pre-pubertal boys exposed to gonadotoxic treatment. Completion of spermatogenesis after in vitro maturation is one of the future uses of harvested testicular tissue. The purpose of the current study was to evaluate the effects of vitamin A on in vitro maturation of fresh and frozen-thawed mouse pre-pubertal spermatogonial stem cells in an organ culture system.

The toxicity of cancer therapies can affect all organs and tissues. Some treatments damage spermatogonial stem cells (SSCs), with a risk of infertility. Storage and reimplantation of frozen testicular tissue is a recent approach tofertilitypreservationfor young boys.
