Which of the following statement is not true with respect to tubectomy or tubal ligation ?

Options

A. It is more difficult than vasectomy and is even more difficult to reverse.
B. No ovulation occurs, hence, no ferilization is posible.
C. It involves ligation of both fallopian tube.
D. The faliure rate of this approach is almost zero percent.

Answer

### Step-by-Step Solution:

1. **Understanding Tubectomy**:
- Tubectomy, also known as tubal ligation, is a surgical method of contraception performed on females. It involves cutting and ligating (tying off) both fallopian tubes to prevent the egg from traveling to the uterus and sperm from reaching the egg.

2. **Mechanism of Action**:
- In tubectomy, both fallopian tubes are cut and ligated. This prevents the egg, which is released during ovulation, from meeting sperm, thus eliminating the possibility of fertilization.

3. **Evaluating Statements**:
- The question asks which statement is NOT true regarding tubectomy. We need to analyze the given statements:
- **Statement A**: "It is more difficult than vasectomy and even more difficult to reverse."
- This statement is true. Tubectomy is generally considered more complex than vasectomy (which is a male procedure).
- **Statement B**: "No ovulation occurs hence no fertilization is possible."
- This statement is NOT true. Ovulation does occur in tubectomy; the egg is just unable to reach the uterus due to the ligation of the fallopian tubes.
- **Statement C**: "It involves ligation of both fallopian tubes."
- This statement is true. Tubectomy involves the ligation of both fallopian tubes.
- **Statement D**: "The failure rate of this approach is almost 0%."
- This statement is true. Tubectomy is a highly effective method of contraception with a very low failure rate.

4. **Conclusion**:
- The statement that is NOT true is **Statement B**: "No ovulation occurs hence no fertilization is possible." Therefore, the correct answer to the question is **Option B**.
