Which of the following is hormone releasing IUD?

Options

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

Answer

To determine which of the following is a hormone-releasing IUD, we can follow these steps:

### Step 1: Understand the Types of IUDs
Intrauterine devices (IUDs) are classified into two main types: hormone-releasing IUDs and copper-releasing IUDs.

### Step 2: Identify the Options
The options provided are:
1. Lipids loop
2. Copper 7
3. LNG 20
4. Multiload 375

### Step 3: Analyze Each Option
- **Lipids loop**: This is not a commonly recognized IUD and does not fall under the category of hormone-releasing IUDs.
- **Copper 7**: This is a copper-releasing IUD. It works by decreasing sperm motility and preventing fertilization.
- **LNG 20**: This is a hormone-releasing IUD. It releases levonorgestrel, which makes the uterine environment unsuitable for implantation and creates a hostile environment for sperm.
- **Multiload 375**: This is also a copper-releasing IUD. Similar to Copper 7, it prevents fertilization by affecting sperm motility.

### Step 4: Conclusion
Based on the analysis, the correct answer is **C, LNG 20**, as it is the only hormone-releasing IUD among the options provided.
