Sperm has several components out of which the function of the acrosome is to:

1. Produce base to neutralize the acidic environment of the female reproductive system
2. Propel the sperm as they swim through the fluid of the female reproductive tract
3. Release an enzyme that breaks down the membrane of the ovum
4. Metabolise the sugars provided by the semen for energy

3. the sperms are transported into cervix within 48 hrs of release of ovum in uterus
