Spermatogonial stem cells (SSCs) are a subset of undifferentiated type A spermatogonia which have the capacity to self‐renew to maintain the SSC pool as well as to differentiate to ultimately form sperm. SSCs represent a rare cell population, constituting ∼0.03% of all germ cells in the adult mouse testis (Tegelenbosch & de Rooij, ). The lack of definite phenotypical, morphological, or biochemical markers that can unequivocally identify SSCs makes it impossible to isolate SSCs for in vitro studies. However, SSCs can be relatively enriched from a testicular cell suspension by various in vivo and/or in vitro approaches.For in vivo enrichment, neonatal, and prepubertal testes serve as the preferred source for harvesting germ cells as gonocytes/spermatogonia are the only type of germ cells present in the seminiferous tubules during those developmental stages (Bellve
