Capacitation occurs in                    [2017]
1 epididymis  
2 vas deferens  
3 female reproductive tract  
4 rete testis  

Ans.

(3)

The sperms in the female’s genital tract are made capable of fertilising the egg by secretions of the female genital tract. These secretions remove coating substances deposited on the surface of the sperms particularly those on the acrosome. Thus, the receptor sites on the acrosome are exposed and sperm becomes active to penetrate the egg. This phenomenon of sperm activation in mammals is known as capacitation.
