Spermatogenesis and Cryptorchidism [PDF]

Frontiers in Endocrinology, 2014
Cryptorchidism represents the most common endocrine disease in boys, with infertility more frequently observed in bilateral forms. It is also known that undescended testes, if untreated, lead to an increased risk of testicular tumors, usually seminomas, arising from mutant germ cells.
