Options

A. It prevents the production of sperms in the tests
B. It prevents the production of semen
C. It prevents the movement of sperms into the urethra
D. It prevents a man from having an ecrection

Explanation

**Step-by-Step Solution:**

1. **Understanding Vasectomy**:
- Vasectomy is a surgical procedure for male sterilization. It is a permanent method of contraception that prevents sperm from being included in the semen during ejaculation.

2. **Mechanism of Vasectomy**:
- During the procedure, the surgeon cuts and seals the vas deferens, which are the tubes that carry sperm from the testicles to the urethra. This prevents sperm from mixing with semen.

3. **Evaluating the Statements**:
- **Statement 1**: "It prevents the production of sperms in the testes."
- This statement is incorrect. Vasectomy does not stop the production of sperm; it only prevents sperm from entering the urethra.

- **Statement 2**: "It prevents the production of semen."
- This statement is also incorrect. Semen is still produced; however, it does not contain sperm after a vasectomy.

- **Statement 3**: "It prevents the movement of sperms into the urethra."
- This statement is correct. The main function of a vasectomy is to block the movement of sperm into the urethra.

- **Statement 4**: "It prevents a man from having an erection."
- This statement is incorrect. A man can still achieve an erection and ejaculate, but the semen will not contain sperm.

4. **Conclusion**:
- The correct statement regarding vasectomy is that it prevents the movement of sperms into the urethra.

**Final Answer**: The correct option is **Statement 3**: "It prevents the movement of sperms into the urethra."
