The acrosome is a specialized organelle found on sperm cells. It wraps around the head of the sperm and contains enzymes designed to help the sperm penetrate the egg by breaking down the proteins in the egg's cell wall.n a process known as the acrosome reaction, the sperm cell fuses with the egg, releases the enzymes, and enters the egg to complete fertilization. This structure is of particular interest to fertility specialists, as problems with the acrosome reaction can cause fertility issues.
