Which of the contraceptive release mineral ions to inhibit the motility of a sperm ?

Options

A. Condoms
B. Copper T
C. Saheli
D. Norplant

Answer

To solve the question of which contraceptive releases mineral ions to inhibit the motility of sperm, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for a contraceptive method that releases mineral ions specifically to inhibit sperm motility.

2. **Review the Options**: The options provided are:
- A) Condoms
- B) Copper T
- C) Saheli
- D) Not Plant

3. **Analyze Each Option**:
- **A) Condoms**: These are barrier methods that prevent sperm from entering the female reproductive tract. They do not release any ions.
- **B) Copper T**: This is an intrauterine device (IUD) that releases copper ions (Cu²⁺) into the uterus. These ions create an environment that is toxic to sperm, inhibiting their motility and preventing fertilization.
- **C) Saheli**: This is a hormonal contraceptive that does not involve the release of mineral ions.
- **D) Not Plant**: This option does not refer to a known contraceptive method.

4. **Identify the Correct Answer**: Based on the analysis, the Copper T is the only contraceptive that releases mineral ions (copper ions) to inhibit sperm motility.

5. **Conclusion**: The correct answer to the question is **B) Copper T**.
