Correct Answer » D
Explanation
|
|
- Capacitation is the physiological process by which sperm acquire the ability to fertilize the ovum.
- Freshly ejaculated sperm cannot fertilize an ovum immediately.
Site of Capacitation
- Capacitation occurs in the female reproductive tract.
- Mainly occurs in the uterus and fallopian tubes.
- In single-best-answer MCQs, “Uterus” is the expected answer.
Why Option D is Correct
- Sperm undergo biochemical changes in the uterine and tubal environment.
- These changes enable the acrosome reaction and fertilization.
Why Other Options are Incorrect
A. Epididymis
- Site of sperm maturation and storage.
- Capacitation does not occur here.
B. Vas deferens
- Functions in transport of sperm.
- Not a site of capacitation.
C. Vagina
- Receives semen after ejaculation.
- Not the primary site of capacitation.
