The function of the hyaluronidase enzyme is:

penetration of the sperm into the ovum

entrance of the sperm into the fallopian tube

entrance of the sperm into the vagina

inactivation of sperm after their failure to fertilizer ovum

Explanation

Hyaluronidase is an important enzyme involved in the catabolism of both hyaluronic acid and chondroitin sulfate.

The release of this enzyme from the acrosome breaks down the intercellular connections of the cumulus cells and allows sperm to penetrate between the cells to the corona layer.
