Capacitation occurs in

Options

A. epididymis
B. vas efferens
C. vas deferens
D. female genital tract

Answer

**Step-by-Step Solution:**

1. **Understanding Capacitation**: Capacitation is a physiological process that spermatozoa (sperm cells) undergo to gain the ability to penetrate and fertilize the ovum (egg). Initially, sperm cells are not capable of fertilization.

2. **Location of Capacitation**: Capacitation occurs within the female reproductive tract. This is where the sperm undergoes the necessary changes to become capable of fertilization.

3. **Duration of Capacitation**: After the sperm is deposited in the female's reproductive tract, it takes approximately 10 hours for capacitation to occur. During this time, the sperm undergoes biochemical changes that enhance its ability to fertilize the ovum.

4. **Survival of Sperm**: Once inside the female reproductive tract, sperm can survive for about 2 to 5 days. However, they must undergo capacitation before they can fertilize the egg.

5. **Conclusion**: Therefore, the correct answer to the question "Capacitation occurs in" is the female genital tract.
