What will happen to spermatozoa at `0^(@)C` temperature :-

Options

A. All sperm will die
B. There will be not change
C. They will become inactive temporarily
D. Tails will be lost

Answer

### Step-by-Step Solution:

1. **Understanding Spermatozoa**: Spermatozoa, or sperm cells, are the male reproductive cells responsible for fertilization. They are motile and consist of a head, neck, and tail, which aids in their movement.

2. **Optimal Temperature for Sperm Function**: Spermatozoa function best at human body temperature, which is approximately 37 degrees Celsius. At this temperature, they are active and capable of swimming effectively.

3. **Effect of Low Temperature**: When exposed to very low temperatures, such as 0 degrees Celsius, spermatozoa experience a significant drop in temperature. This cold environment can lead to a state of inactivity.

4. **Temporary Inactivity**: At 0 degrees Celsius, spermatozoa do not die immediately. Instead, they become temporarily inactive. This is a reversible process; when the sperm is brought back to a normal temperature, they can regain their motility and function.

5. **Eliminating Incorrect Options**:
- **All sperms will die**: This is incorrect because sperm can survive low temperatures without dying immediately.
- **There will not be any change**: This is also incorrect as there is a significant change in their activity level.
- **The tails will be lost**: This is incorrect because the structure of the sperm does not disintegrate at low temperatures; they simply become inactive.

6. **Conclusion**: The correct answer is that spermatozoa will become inactive temporarily at 0 degrees Celsius.
