Choose the right one among the statements given below.

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

Answer

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

### Step-by-Step Solution:

1. **Understanding IUDs**:
- IUDs are intrauterine devices used for contraception. They are inserted into the uterus to prevent pregnancy.

2. **Evaluating Option 1**:
- **Statement**: "IUDs are generally inserted by user herself."
- **Analysis**: This statement is incorrect. IUDs must be inserted by a qualified medical professional, not by the user herself.

3. **Evaluating Option 2**:
- **Statement**: "IUDs increase phagocytosis reaction in the uterus."
- **Analysis**: This statement is correct. Some types of IUDs, particularly those that are copper-based, can induce a phagocytic response in the uterus, which helps to eliminate sperm.

4. **Evaluating Option 3**:
- **Statement**: "IUDs suppress gametogenesis."
- **Analysis**: This statement is incorrect. IUDs do not suppress gametogenesis, which is the process of forming gametes (sperm and eggs).

5. **Evaluating Option 4**:
- **Statement**: "IUDs once inserted need not to be replaced."
- **Analysis**: 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 evaluating all options, the correct statement regarding IUDs is: **"IUDs increase phagocytosis reaction in the uterus."** Therefore, the correct answer is **Option B**.
