Majority of mammalian spermatozoa acquire capacitation in

Options

A. Epididymis
B. Seminal vesicle
C. Female reproductive tract
D. Urethra

Answer

**Step-by-Step Solution:**

1. **Understanding Capacitation**: Capacitation is a physiological process that sperm undergo to gain the ability to fertilize an egg. It involves changes in the sperm membrane and is crucial for successful fertilization.

2. **Location of Capacitation**: Capacitation primarily occurs in the female reproductive tract. This is where the sperm undergoes the necessary changes to become mature and capable of fertilizing an ovum.

3. **Role of the Epididymis**: Before reaching the female reproductive tract, sperm are stored in the epididymis, where they gain a coating of seminal plasma. However, this does not complete the capacitation process.

4. **Changes in the Female Reproductive Tract**: Once the sperm enter the female reproductive tract, they encounter various substances and membranes, such as the zona pellucida and corona radiata. These structures help in the removal of the inhibitory substances from the sperm surface, allowing the sperm to become capacitated.

5. **Conclusion**: The majority of mammalian spermatozoa acquire capacitation in the female reproductive tract, making it the correct answer to the question.

**Final Answer**: The majority of mammalian spermatozoa acquire capacitation in the female reproductive tract.
