Zoology - Human Reproduction Question with Solution | TestHub

The acrosome is the cap-like structure on the front end of a spermatozoon. It breaks down just before fertilization (the acrosome reaction), releasing a number of hydrolytic enzymes, also called sperm lysins that assist penetration between the follicle cells that surround the ovum, thus facilitating fertilization. Failure of the acrosome reaction is a cause of male infertility.
