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 might be easily guided by hand into its proper position in the scrotum - the bag of skin hanging behind the penis - during a physical exam. For most boys, the problem of a retractile testicle goes away sometime before or during puberty. The testicle moves to its correct location in the scrotum and stays there permanently. In fewer than 5 percent of cases, the retractile testicle remains in the groin and is no longer movable. When this happens, the condition is called an ascending testicle or an acquired undescended testicle. Signs and symptoms of a retractile testicle include: The testicle may be moved by hand from the groin into the scrotum and won't immediately retreat to the groin. The testicle might spontaneously appear in the scrotum and remain there for a time. The testicle might spontaneously disappear again for a time. A retractile testicle is likely to descend on its own before or during puberty. If the testicle has ascended - no longer movable by hand doctor will likely recommend surgery to move the testicle permanently into the scrotum.
