ovum before fertilization
Capacitation is the term used to describe the phenomena of sperm activation for fertilisation in animals. It takes place before fertilisation. A metabolic process called capping takes place in the female reproductive system. Before fertilization, the female reproductive tract secretes something that removes the coating materials from the sperms' surfaces that are in the acrosome. Once the coating materials have been removed, the acrosomal site is active and the sperm becomes active to penetrate the egg, and then fertilization takes place.
Capacitation takes between five and six hours to finish.
The final answer is Capacitation refers to changes in sperm before fertilization.
