When my son was born he was perfect and on time. No problems except that his left testicle had not dropped. He is now almost six months old and it still has not moved. Our doctor says that if it is still there when he is one year old, he will require surgery to pull it into place, otherwise, he will not be able to have children. The doctor has also mentioned talking to a specialist about possible hormone therapy before he is a year old, but he doesn't know for sure if that is a possibility.
Testicles originate in the abdomen while the fetus is developing.
As the fetus grows, the testes descend into the scrotum. Male infants born at term should have both testicles descended. Many males have what are called retractile testes. This is a benign condition in which the testes tend to lie high in the scrotum such that the scrotum may look empty especially when it is cold. Differentiating this condition from undescended testes is important and done by examination.
