Question

Preparation of sperm before penetration of ovum is_______________.

• A. Spermiation
• B. Cortical reaction
• C. Spermiogenesis
• D. Capacitation

Answer 1

The correct option is D Capacitation

The secretions of the female genital tract remove coating substances deposited on the surface of the sperms particularly those on the acrosome. Thus, the receptor sites on the acrosome get exposed and sperm become active to penetrate the egg. This phenomenon of sperm activation in mammals is known as capacitation.

So, The correct answer is (D).
