Options

A. IUDs are generally inserted by the user herself
B. IUDs increase phagocytosis reaction in the uterus
C. IUDs suppress gametogenesis
D. IUDs once inserted need not be replaced

Explanation

To solve the question regarding the statements about Intrauterine Devices (IUDs), we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Understanding IUDs**:
- IUDs (Intrauterine Devices) are contraceptive devices that are inserted into the uterus to prevent pregnancy. They are effective methods of contraception.

2. **Analyzing the Statements**:
- **Statement 1**: "IUDs are generally inserted by the user herself."
- This statement is **incorrect**. IUDs must be inserted by a healthcare professional, not by the user herself.

- **Statement 2**: "IUDs increase phagocytosis reaction in the uterus."
- This statement is **correct**. Certain types of IUDs, particularly copper-releasing IUDs, can enhance the phagocytosis of sperm, thereby reducing the chances of fertilization.

- **Statement 3**: "IUDs suppress chemitogenesis."
- This statement is **incorrect**. IUDs do not suppress gametogenesis; they primarily prevent ovulation and fertilization.

- **Statement 4**: "IUDs once inserted need not to be replaced."
- This statement is **incorrect**. Although IUDs can last for several years (up to 10 years for some types), they do need to be replaced after their effective lifespan.

3. **Conclusion**:
- After analyzing all the statements, the only correct statement is **Statement 2**: "IUDs increase phagocytosis reaction in the uterus."

### Final Answer:
The correct statement is: **IUDs increase phagocytosis reaction in the uterus.**
