Undescended testicles


Shortly before birth, the testes which have formed in a baby boy during the mother’s pregnancy, descend into the scrotum. However, sometimes this doesn’t happen and one or both testicles stay in the abdomen and only move part the way down. The problem with this is that normal sperm production requires a temperature a few degrees lower than the body temperature, which is why testicles hang down in the scrotal sac outside the body. If a man has two undescended testicles and they’re not corrected from a young age, it can cause infertility.
