Retractile testicles cause parents a lot of worry. Do they need surgery or are they OK? Are the right judgements being made? There is one foolproof way to identify retractile testicles:
The medical team will take your son into an operating theatre and anaethetize him.
The anaesthetic makes your son’s muscles relax. If the testicle is retractile it will come down into his scrotum and they will not operate (this happened to one of my testicles)
If the testicle does not appear in his scrotum they will know for certain it is an undescended testicle stuck inside him. The surgeon will make a cut in your son’s groin and/or scrotum and forcefully bring the testicle down. (They did this to my other testicle)
If you really want to know if your son’s testicles are retractile, let them anaesthetise him.
The testicle was retractile but they operated?
Given 30-40% of retractile testicles later become ascended testicles (acquired cryptorchidism) and need surgery, your surgeon may decide to operate anyhow. Especially if the retractile testicle sits at the top of the scrotum, and doesn’t reach to the bottom of the sac.
This could be unnecessary surgery but avoids the chance of giving your son a second anaesthetic.
