D. IUDs once inserted need not be replaced.

Answer

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

### Step-by-Step Solution:

1. **Evaluate Statement 1**: "IUDs are generally inserted by the user herself."
- This statement is **incorrect**. IUDs are typically inserted by medical practitioners or gynecologists, not by the users themselves.

2. **Evaluate Statement 2**: "IUDs increase phagocytosis reaction in the uterus."
- This statement is **correct**. IUDs, particularly medicated ones, can increase the phagocytic reaction in the uterus. They release substances (like copper) that enhance the immune response, leading to increased phagocytosis of sperm.

3. **Evaluate Statement 3**: "IUDs suppress gametogenesis."
- This statement is **incorrect**. IUDs do not suppress gametogenesis; they inhibit ovulation, which means they prevent the release of eggs from the ovaries but do not affect the formation of gametes.

4. **Evaluate Statement 4**: "IUDs once inserted need not to be replaced."
- This statement is **incorrect**. IUDs have a specific lifespan and need to be replaced after a certain period (usually 5 to 10 years, depending on the type).

### Conclusion:
The only correct statement among the options provided is **Statement 2**: "IUDs increase phagocytosis reaction in the uterus."
