Which of the following statements is not true w.r.t. 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 fertilization is possible
C. It involves ligation of both fallopian tubes
D. The failure rate of this approach is almost zero percent

Explanation

To determine which statement is not true with respect to tubectomy or tubal ligation, we can analyze each of the provided statements step by step:

### Step 1: Understand Tubectomy
- Tubectomy, or tubal ligation, is a surgical procedure for female sterilization. It involves cutting and tying the fallopian tubes to prevent the ovum from reaching the uterus, thus preventing fertilization.

### Step 2: Evaluate Each Statement
1. **Statement 1: It is more difficult than vasectomy and is even more difficult to reverse.**
- This statement is generally considered true. Tubectomy is indeed more complex than vasectomy due to the anatomical differences and the surgical approach involved.

2. **Statement 2: No ovulation occurs, hence no fertilization is possible.**
- This statement is **not true**. In tubectomy, ovulation still occurs; the ovaries release eggs, but the eggs cannot reach the uterus for fertilization due to the blocked fallopian tubes.

3. **Statement 3: It involves ligation of both fallopian tubes.**
- This statement is true. Tubectomy involves the ligation (tying off) of both fallopian tubes to prevent the passage of the egg.

4. **Statement 4: The failure rate of this approach is almost 0%.**
- This statement is also true. Tubectomy is considered a very effective method of contraception with a low failure rate.

### Step 3: Conclusion
- Based on the evaluation, the statement that is **not true** with respect to tubectomy is **Statement 2: No ovulation occurs, hence no fertilization is possible.**

### Final Answer
The statement that is not true with respect to tubectomy or tubal ligation is: **No ovulation occurs, hence no fertilization is possible.**
