Cu ions released from copper-releasing Intra Uterine Device ( IUDs) except ?

Options

A. Prevent ovulation
B. make uterus unsuitable for implantation
C. Increases phagocytosis of sperms
D. Increases phagocytosis of sperms

Answer

To answer the question about the functions of copper ions released from copper-releasing Intra Uterine Devices (IUDs), we need to identify the incorrect function among the provided options. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Function of Copper IUDs
Copper-releasing IUDs, such as the Copper-T, are devices placed inside the uterus to prevent pregnancy. They release copper ions which have specific effects on the reproductive system.

### Step 2: Identify the Functions of Copper IUDs
1. **Makes the Uterus Unsuitable for Implantation**: The copper ions create an environment in the uterus that is not conducive for the implantation of a fertilized egg. This is one of the primary functions of copper IUDs.

2. **Increases Phagocytosis of Sperm**: The copper ions also enhance the action of phagocytosis, where immune cells in the uterus destroy sperm cells that enter the female reproductive tract, reducing the chances of fertilization.

### Step 3: Evaluate the Options
Now, let’s evaluate the options provided in the question:
- **Prevent Ovulation**: This option suggests that copper IUDs prevent the process of ovulation (the release of a mature egg from the ovary). However, this is incorrect. Copper IUDs do not prevent ovulation; they allow ovulation to occur but prevent implantation.

### Step 4: Conclusion
Based on the analysis, the incorrect function of copper ions released from copper-releasing IUDs is:
- **Prevent Ovulation**.

### Final Answer
The correct answer is: **Prevent Ovulation**.
