Which of the following is a non-medicated intrauterine device (IUD) ?

Options

A. CuT
B. Lippes Loop
C. Cu7
D. LNG-20

Explanation

To determine which of the following is a non-medicated intrauterine device (IUD), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of IUDs**:
- IUDs can be classified into two main categories: medicated and non-medicated. Medicated IUDs release substances such as copper or hormones to prevent pregnancy, while non-medicated IUDs do not release any active substances.

2. **Identify the Options**:
- The question likely provides several options for IUDs. Common examples include the Copper T (CuT), Cu7, LNG 20, and the Lipase loop.

3. **Analyze Each Option**:
- **Copper T (CuT)**: This is a medicated IUD that releases copper ions to prevent fertilization.
- **Cu7**: Similar to the Copper T, this is also a medicated IUD that releases copper.
- **LNG 20**: This is a hormonal IUD that releases levonorgestrel, making it a medicated option.
- **Lipase Loop**: This is a non-medicated IUD made of rubber. It acts as a physical barrier and does not release any hormones or copper.

4. **Determine the Correct Answer**:
- Based on the analysis, the Lipase loop is identified as the non-medicated intrauterine device.

5. **Conclusion**:
- The correct answer to the question is the Lipase loop.
