Which of the following is a copper releasing IUD?

Options

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

Answer

To determine which of the following is a copper-releasing IUD, we can analyze the options provided based on the information about intrauterine devices (IUDs).

### Step-by-Step Solution:

1. **Understand IUD Types**:
- There are two main types of IUDs: medicated and non-medicated. Medicated IUDs can release hormones or copper, while non-medicated IUDs do not release any substances.

2. **Identify Non-Medicated IUD**:
- The first option mentioned is Lippe's loop, which is classified as a non-medicated IUD. Therefore, it does not release copper.

3. **Identify Copper-Releasing IUDs**:
- The transcript mentions multiload 375 as an example of a copper-releasing IUD. This indicates that multiload 375 releases copper ions.

4. **Additional Examples**:
- Other examples of copper-releasing IUDs include CuT and Cu 7. These are also recognized for their copper-releasing properties.

5. **Function of Copper IUDs**:
- Copper ions released by these IUDs are known to reduce sperm mortality and fertilizing capacity, which helps in preventing pregnancy.

6. **Identify Hormone-Releasing IUD**:
- The transcript also refers to LNG-20 as a hormone-releasing IUD, which releases progesterone. This is not relevant to the question since it does not release copper.

7. **Conclusion**:
- Based on the information provided, the correct answer to the question "Which of the following is a copper-releasing IUD?" is **multiload 375**.

### Final Answer:
**Multiload 375** is a copper-releasing IUD.
