Answer

To determine which statements are correct regarding surgical methods of contraception, we will evaluate each statement one by one.

### Step-by-Step Solution:

1. **Statement I: In female, it is called tubectomy.**
- This statement is **correct**. The surgical method of contraception for females is indeed called tubectomy, where the fallopian tubes are cut and sealed to prevent the egg from reaching the uterus.

2. **Statement II: It is reversible.**
- This statement is **incorrect**. Surgical methods of contraception, such as tubectomy and vasectomy, are generally considered permanent and not easily reversible. While there are procedures that attempt to reverse them, success rates can vary significantly.

3. **Statement III: It blocks gamete transport in female.**
- This statement is **correct**. Tubectomy blocks the transport of gametes (eggs) in females by preventing the egg from traveling through the fallopian tubes, thus preventing fertilization.

4. **Statement IV: It can be done both in females and males.**
- This statement is **correct**. Surgical methods of contraception can be performed on both males (vasectomy) and females (tubectomy).

### Summary of Correct Statements:
- Correct statements: I, III, and IV.
- Incorrect statement: II.

### Final Answer:
The correct statements regarding surgical methods of contraception are:
- I. In female, it is called tubectomy.
