Which of the following is hormone releasing IUD?

Options

A. Lippes loop
B. Cu7
C. LNG-20
D. Multiload 375

Answer

To solve the question "Which of the following is a hormone releasing IUD?" we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: We need to identify which option among the given choices is a hormone-releasing intrauterine device (IUD).

2. **Identify the Options**: The options provided are:
- Lepus loop
- Copper 7
- LNG 20
- Multiload 375

3. **Define IUD**: An intrauterine device (IUD) is a small device that a doctor places in a woman's uterus to prevent pregnancy. There are two main types of IUDs:
- Copper-releasing IUDs
- Hormone-releasing IUDs

4. **Differentiate Between Types of IUDs**:
- **Copper-releasing IUDs**: These release copper ions which help in preventing sperm movement and fertilization of the ovum.
- **Hormone-releasing IUDs**: These release hormones (usually progesterone) that make the uterine lining unsuitable for implantation and create a hostile environment for sperm.

5. **Analyze Each Option**:
- **Lepus loop**: This is a type of copper IUD.
- **Copper 7**: This is also a copper-releasing IUD.
- **LNG 20**: This is a hormone-releasing IUD that releases the hormone levonorgestrel.
- **Multiload 375**: This is another type of copper IUD.

6. **Select the Correct Answer**: Based on the analysis, the only hormone-releasing IUD among the options is **LNG 20**.

### Final Answer:
The correct answer is **C, LNG 20**.
