Answer

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

### Step-by-Step Solution:

1. **Understanding IUDs**:
- IUDs, or Intrauterine Devices, are contraceptive devices inserted into the uterus to prevent pregnancy. They are not self-inserted but require a trained professional for insertion.

2. **Analyzing Statement A**:
- **Statement A**: "IUDs are generally inserted by user herself."
- This statement is incorrect. IUDs must be inserted by a healthcare professional, such as a doctor or a trained nurse.

3. **Analyzing Statement B**:
- **Statement B**: "IUDs increase phagocytosis reaction in uterus."
- This statement is correct. IUDs do increase the phagocytosis of sperm in the uterus, which helps prevent fertilization.

4. **Analyzing Statement C**:
- **Statement C**: "IUDs suppress gametogenesis."
- This statement is incorrect. IUDs do not suppress gametogenesis; instead, they primarily affect sperm motility and fertilization capacity.

5. **Analyzing Statement D**:
- **Statement D**: "IUDs once inserted need not to be replaced."
- This statement is also incorrect. IUDs have a specific lifespan and need to be replaced after a certain period, depending on the type of IUD used.

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

### Final Answer:
- The correct statement is **Option B**.
