DefinitionBy 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, the time when an out-of-place testicle moves to its correct location in the scrotum and stays there permanently.
About a quarter of the time, the retractile testicle stays up in the groin and is no longer movable. When this happens, the condition is called an ascending testicle.
