The testicles are located outside of the male body because sperm cannot tolerate body heat. In general, the testicles of male babies are checked by a paediatrician after birth. In some cases, the testicles have not migrated out of the abdominal cavity completely or at all. In this case the child’s parents are advised that the infant should have a testicular operation. The reason for this ‘non-migration’ of the testicles in the infant can be genetic. The timely treatment of undescended testicles can lead to an improvement in later fertility.
If the testicles remain too far inside the abdominal cavity and no surgical treatment has been carried out, this can later result in reduced semen quality.
