Scientists found a genetic change which makes men less fertile. The genetic change was found in a gene called DEFB126. This gene codes for a protein that clings to sperm, helping them swim through a woman’s body to fertilize the egg. Sperm lacking in the substance find it harder to swim to the egg.
However, according to the scientists a man with the altered gene can also get his partner pregnant but taking a longer time.
