Vasectomy has no effect on the sexual life of male because:

B. Vasectomy affects the hormonal secretion but the person can ejaculate semen with normal number of sperms
C. He cannot ejaculate but the hormone levels are normal
D. Vasectomy does not affect the sexual desire but can cause impotency

Explanation

**Step-by-Step Solution:**

1. **Understanding Vasectomy**: Vasectomy is a surgical procedure in which a part of the vas deferens (the duct that carries sperm from the testicles) is cut and tied. This procedure is primarily used as a method of contraception to prevent pregnancy.

2. **Function of Vasectomy**: The main function of a vasectomy is to block sperm from being included in the semen that is ejaculated. While sperm production continues in the testes, the sperm cannot travel through the vas deferens to mix with semen.

3. **Hormonal Effects**: After a vasectomy, the production of male sex hormones, particularly testosterone, remains normal because testosterone is produced by the testes and is not affected by the cutting of the vas deferens.

4. **Ejaculation**: Men who have undergone a vasectomy can still ejaculate. However, the semen will not contain sperm, as they are blocked from reaching the ejaculate due to the surgical procedure.

5. **Evaluating the Options**:
- **Option 1**: "He can still ejaculate and has normal secretion of sex hormones in the blood." This is correct.
- **Option 2**: "Vasectomy affects the hormonal secretion but the person can ejaculate semen with normal number of sperm." This is incorrect because while the person can ejaculate, the semen will not contain sperm.
- **Option 3**: "He cannot ejaculate but the hormone levels are normal." This is incorrect; he can still ejaculate.
- **Option 4**: "Vasectomy does not affect sexual desire but can cause impotency." This is incorrect; vasectomy does not cause impotency.

6. **Conclusion**: The correct answer is that vasectomy has no effect on the sexual life of a male because he can still ejaculate and has normal secretion of sex hormones in the blood.

**Final Answer**: The correct option is the first one: "He can still ejaculate and has normal secretion of sex hormones in the blood."
