Which of the following is a hormone releasing Intra Uterine Device (IUD)?

Options

A. Vault
B. Multiload 375
C. LNG-20
D. Cervical cap

Answer

To determine which of the options provided is a hormone-releasing intrauterine device (IUD), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of IUDs**:
- There are two main types of intrauterine devices: Copper-releasing IUDs and Hormone-releasing IUDs.
- Copper-releasing IUDs (like Multiload 375) release copper ions that are toxic to sperm, preventing fertilization.
- Hormone-releasing IUDs (like LNG 20) release hormones, specifically progestin, which alters the uterine lining and cervical mucus.

2. **Analyze the Options**:
- **Void**: This option does not correspond to any known IUD.
- **Multiload 375**: This is a copper-releasing IUD.
- **LNG 20**: This is a hormone-releasing IUD that releases levonorgestrel, a type of progestin.
- **Cervical Cap**: This is not an IUD; it is a barrier method of contraception.

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

### Conclusion:
The correct answer is **LNG 20**.
