Testiscles should lower from the abdomen into the scrotum before birth. Some boys are born with one or both testicles still inside the abdomen or groin. This is called undescended testicles. Orchiopexy is a surgery to lower the testicle(s) into the scrotum.

Orchiopexy is done to treat undescended testicles. The surgery may improve fertility. Undescended testicles also have a higher risk of developing cancer later in life. Having the testicle in the scrotum makes it easier to check for early signs of cancer.
