Human fertilization. Computer artwork of a single sperm cell (spermatozoon) attempting to fertilise a human egg cell (ovum, round, lower right). The sperm cell consists of a head section and a tail section. It is trying to penetrate the egg cell and release the genetic material contained in its head. If it succeeds, rapid chemical changes prevent other sperm cells from entering the egg cell.
