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 fertilization is possible
C. It involves ligation of both fallopian tubes.
D. The failure rate of this approach is almost zero percent.

Answer

To determine which statement is not true with respect to tubectomy or tubal ligation, we need to analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding Tubectomy**: Tubectomy, also known as tubal ligation, is a surgical procedure for female sterilization. It involves cutting and tying the fallopian tubes to prevent pregnancy.

2. **Evaluating the Statements**:
- **Statement 1**: "It is more difficult than vasectomy and is even more difficult to reverse."
- **Analysis**: This statement is true. Tubectomy is generally considered more complex than vasectomy due to the surgical procedure involved and the anatomical differences. Additionally, reversing a tubectomy is more complicated than reversing a vasectomy.

- **Statement 2**: "No ovulation occurs, hence no fertilization is possible."
- **Analysis**: This statement is not true. In tubectomy, ovulation continues as normal; it is the passage of the egg through the fallopian tubes that is blocked. Therefore, fertilization cannot occur, but ovulation does happen.

- **Statement 3**: "It involves ligation of both fallopian tubes."
- **Analysis**: This statement is true. Tubectomy involves the ligation (cutting and tying) of both fallopian tubes to prevent the egg from reaching the uterus.

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

3. **Conclusion**: The statement that is not true with respect to tubectomy is the second one: "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."**
