Which of the following is hormone releasing IUD?

Options

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

Answer

To determine which of the following is a hormone-releasing intrauterine device (IUD), we need to analyze the options provided:

1. **LNG 20**
2. **Multiload 375**
3. **Lipid Loop**
4. **Copper 7**

### Step-by-Step Solution:

**Step 1: Understand IUDs**
- Intrauterine devices (IUDs) are small, T-shaped devices inserted into the uterus to prevent pregnancy. They can be classified into two main types: hormone-releasing and copper-releasing IUDs.

**Step 2: Identify the Options**
- **LNG 20**: This is a hormone-releasing IUD that contains the hormone levonorgestrel (a form of progesterone).
- **Multiload 375**: This is a copper-releasing IUD that uses copper to prevent sperm movement and fertilization.
- **Lipid Loop**: This is a medicated IUD, but it does not release hormones like levonorgestrel.
- **Copper 7**: This is another copper-releasing IUD that uses copper for its contraceptive effect.

**Step 3: Analyze the Hormone-Releasing IUD**
- Among the options, LNG 20 is specifically designed to release the hormone progesterone, which helps in preventing pregnancy by creating an environment in the uterus that is hostile to sperm.

**Step 4: Conclusion**
- The correct answer to the question "Which of the following is a hormone-releasing IUD?" is **LNG 20**.

### Final Answer:
**LNG 20** is the hormone-releasing IUD.
