Which of the following statements are correct regarding sterilisation?
I. Sterilisation is a form of permanent contraception.
II. Sterilisation inhibits gametogenesis.
III. Sterilisation can be done both in males and females.
IV. Tubectomy is the sterilisation procedure done in males.

Options

A. I and II
B. I and III
C. III and IV
D. III and II

Answer

To determine which statements regarding sterilization are correct, let's analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement I: Sterilisation is a form of permanent contraception.**
- **Analysis:** This statement is true. Sterilization is indeed a method of permanent contraception that prevents pregnancy by blocking the reproductive pathways.

2. **Statement II: Sterilisation inhibits gametogenesis.**
- **Analysis:** This statement is misleading. While sterilization prevents fertilization, it does not inhibit the formation of gametes (sperm in males and eggs in females). Gametogenesis can still occur; however, the gametes cannot meet to form a zygote.

3. **Statement III: Sterilisation can be done both in males and females.**
- **Analysis:** This statement is true. Sterilization procedures are available for both males (vasectomy) and females (tubectomy).

4. **Statement IV: Tubectomy is the sterilisation procedure done in males.**
- **Analysis:** This statement is false. Tubectomy is the sterilization procedure performed in females, where the fallopian tubes are cut or blocked. The male sterilization procedure is called vasectomy.

### Conclusion:
Based on the analysis:
- **Correct Statements:** I and III
- **Incorrect Statements:** II and IV

Thus, the correct answer is that statements I and III are correct regarding sterilization.

### Summary of Correct Statements:
- I. True
- II. False
- III. True
- IV. False

### Final Answer:
The correct statements regarding sterilization are I and III.
