A. No sperms occurs in seminal fluid
B. No sperm occurs in epididymis
C. Vasa deferentia is cut and tied
D. Irreversible sterility

Answer

To determine which statement regarding vasectomy is incorrect, we will analyze each option one by one.

### Step-by-Step Solution:

1. **Understanding Vasectomy**:
- Vasectomy is a surgical procedure for male sterilization. It involves cutting and tying the vas deferens, which are the tubes that carry sperm from the epididymis to the ejaculatory duct.

2. **Analyzing the Options**:
- **Option 1**: "No sperm occurs in seminal fluid."
- This statement is **correct**. After a vasectomy, sperm is not present in the seminal fluid because the sperm cannot travel from the epididymis to the ejaculatory duct.

- **Option 2**: "No sperm occurs in epididymis."
- This statement is **incorrect**. Sperm is still produced in the testes and stored in the epididymis even after a vasectomy. The vasectomy only prevents sperm from being included in the seminal fluid during ejaculation.

- **Option 3**: "Vasa deferentia cut and tied."
- This statement is **correct**. The procedure involves cutting and tying the vas deferens to prevent sperm from entering the ejaculatory duct.

- **Option 4**: "Irreversible sterility."
- This statement is **correct**. Vasectomy is generally considered a permanent form of contraception, although reversal is possible in some cases, it is not guaranteed.

3. **Conclusion**:
- The incorrect statement regarding vasectomy is **Option 2**: "No sperm occurs in epididymis."

### Final Answer:
The incorrect statement regarding vasectomy is: **"No sperm occurs in epididymis."**
