WebAcrosome: The acrosome is present at the anterior end of the elongated nucleus in the sperm head as the cap-like structure. It contains proteolytic enzymes such as hyaluronidase and acrosin that help the sperm in penetrating the ovum through the zona pellucida layer around the ovum and enter the cytoplasm of the ovum. WebThe acrosome is a membrane-bound organelle covering most of the head of the sperm. On interaction with the zona pellucida of the ova, the sperm releases proteolytic enzymes from the acrosome to penetrate and enter the ova. This acrosome reaction may be insufficient, or absent, in some infertile males.
