Read the statements given below . Identify which of them are true and which of them are false and select correct option.
1. An IUD can be inserted by a lady herself into the uterus through her vagina.
2. IUDS increase phagocytosis of sperms in the fallopian tube.
3 Copper ions suppress sperm motility and fertilizing capacity.
4. Hormone releasing IUDs prevents ovulation.

Options

A. 1 - True , 2 - True , 3 - False , 4 - False
B. 1 - False , 2 - False , 3 - True , 4 - True
C. 1 - True , 2 - False , 3 - True , 4 - False
D. 1 - False , 2 - True , 3 - False , 4 - True

Answer

To solve the question, we need to evaluate each of the four statements regarding Intrauterine Devices (IUDs) and determine whether they are true or false.

### Step-by-Step Solution:

1. **Evaluate Statement 1**: "An IUD can be inserted by a lady herself into the uterus through her vagina."
- **Analysis**: IUDs must be inserted by a healthcare professional (doctor or trained nurse) to ensure proper placement and avoid complications. Therefore, this statement is **False**.

2. **Evaluate Statement 2**: "IUDs increase phagocytosis of sperms in the fallopian tube."
- **Analysis**: IUDs do promote phagocytosis of sperm, but this occurs in the uterus, not the fallopian tubes. Thus, this statement is also **False**.

3. **Evaluate Statement 3**: "Copper ions suppress sperm motility and fertilizing capacity."
- **Analysis**: Copper-releasing IUDs (like Copper-T) do indeed release copper ions, which are known to impair sperm motility and reduce their fertilizing capacity. Therefore, this statement is **True**.

4. **Evaluate Statement 4**: "Hormone releasing IUDs prevent ovulation."
- **Analysis**: Hormone-releasing IUDs (such as LNG-20) work by releasing hormones that can prevent ovulation and make the uterine lining less suitable for implantation. Thus, this statement is **True**.

### Summary of Statements:
- Statement 1: **False**
- Statement 2: **False**
- Statement 3: **True**
- Statement 4: **True**

### Correct Option:
Based on the evaluations, the correct option would be the one that identifies statements 3 and 4 as true.
