Capacitation occurs in:

 # Capacitation occurs in:

A. Female genital tract

B. Sertoli cells

C. Rete testis

D. Seminiferous tubules

The correct answer is A. Female genital tract.

Capacitation is the process that sperm undergo in the female reproductive tract to become able to fertilize an egg. It does not happen in the male reproductive organs. 

Capacitation occurs in the female reproductive tract. It’s a crucial step in the maturation of mammalian spermatozoa, rendering them competent to fertilize an oocyte. During capacitation, the sperm undergo biochemical changes that prepare them for the acrosome reaction, allowing penetration of the egg’s outer layer for fertilization. So, the correct answer is A. Female genital tract.
