If your boy has a testicle that moves back and forth between the scrotum and groin (retractile testicle), he usually won’t need treatment. However, regular check-ups are important until puberty to make sure the testicle stays in the correct right place and don’t move back into the belly.
If the testicle hasn’t dropped into the scrotum by 1 year old, or by 18 months at the latest, treatment is needed. In some cases, doctors may recommend starting treatment after 6 months of age if it’s clear the testicle isn’t going to move down on its own.
