Sperm agglutination is a medical condition that is happening in the reproductive organ of males. Specifically, it is the clumping of the sperm due to infection and/or presence of antibodies. Clumping of sperm inhibits its ability to move and fertilize the egg cells. Instead, sperm cells stick to each other.

Sperm agglutination occurs when the immune system attacks its own sperm as foreign thus producing antibodies to fight and annihilate it. Antibodies attach to the sperms which make them clump together thus disabling it to move freely. This affects the fertility of males.
