Undescended testes are usually repaired by what age?
A. 6 monthsMen with bilateral undescended testicles are often infertile. When the testicle is not within the scrotum, it is subjected to a higher temperature, resulting in decreased spermatogenesis. Mengel and coworkers studied 515 undescended testicles by histology and demonstrated a decreasing presence of spermatogonia after 2 years of age. Despite orchidopexy, the incidence of infertility is approximately two times higher in men with unilateral orchidopexy compared with men with normal testicular descent. Consequently, it is now recommended that the undescended testicle be surgically repositioned by 1 year of age.
