By Mayo Clinic staff

A retractile testicle is a testicle that may move back and forth between the scrotum and the groin. When the retractile testicle is residing in the groin, it may be easily guided by hand into its proper position in the scrotum — the bag of skin hanging behind the penis — during a physical examination.

For most boys, the problem of a retractile testicle goes away sometime before or during puberty because this is usually when the testicle permanently moves to its correct location in the scrotum.

Sometimes, the retractile testicle is no longer movable and instead stays up in the groin. When this happens, the testicle is no longer considered a retractile testicle. This condition is called an ascending testicle.
