Which of the following statement is Not true with respect to tubectomy?

Options

A. It is more difficult then vasectomy and is even more difficult to reverse.
B. No ovulation occurs after the tubectomy, hence no fertilization
C. It involves ligation of both fallopian tubes
D. The failure rate of this method is almost zero

Answer

To determine which statement is not true with respect to tubectomy, let's analyze each statement provided in the question:

1. **It is more difficult than vasectomy and is even more difficult to reverse.**
- This statement is true. Tubectomy is indeed considered more complex than vasectomy, and reversing a tubectomy is generally more challenging.

2. **No ovulation occurs after the tubectomy, hence no fertilization.**
- This statement is not true. After a tubectomy, ovulation still occurs; however, the transport of the ovum is blocked due to the ligation of the fallopian tubes. Therefore, fertilization cannot take place, but ovulation does happen.

3. **It involves ligation of both the fallopian tubes.**
- This statement is true. Tubectomy involves cutting and tying both fallopian tubes to prevent the passage of the ovum and sperm.

4. **The failure rate of this method is almost nil.**
- This statement is also true. Tubectomy is considered a very effective method of sterilization, with a very low failure rate.

Based on this analysis, the statement that is not true with respect to tubectomy is the second one: **"No ovulation occurs after the tubectomy, hence no fertilization."**

### Step-by-step Solution:
1. **Identify the statements regarding tubectomy.**
- Analyze each statement provided in the question.

2. **Evaluate the first statement:**
- Confirm that it is true that tubectomy is more difficult than vasectomy and harder to reverse.

3. **Evaluate the second statement:**
- Determine that this statement is false because ovulation still occurs after tubectomy, but the transport of the ovum is blocked.

4. **Evaluate the third statement:**
- Confirm that it is true that tubectomy involves ligation of both fallopian tubes.

5. **Evaluate the fourth statement:**
- Confirm that it is true that the failure rate of tubectomy is almost nil.

6. **Conclude which statement is not true.**
- Identify the second statement as the one that is not true.
