Optimal temperature for spermatogenesis :-

Options

A. Normal body temperature (`37^(@)`C)
B. `43^(@)-45^(@)` C
C. `39^(@)-40^(@)C`
D. `34.5-35^(@)C`

Answer

**Step-by-Step Solution:**

1. **Understand the Process of Spermatogenesis**: Spermatogenesis is the process of sperm cell development that occurs in the male reproductive system, specifically in the testes.

2. **Identify the Location of Spermatogenesis**: This process takes place in the testes, which are housed in the scrotum.

3. **Recognize the Temperature Requirement**: The testes need to be maintained at a specific temperature for optimal spermatogenesis to occur. This temperature is lower than the normal body temperature.

4. **Determine Normal Body Temperature**: The average normal body temperature in humans is approximately 37 degrees Celsius.

5. **Calculate the Optimal Temperature**: Since spermatogenesis requires a temperature that is about 2 to 2.5 degrees Celsius lower than the normal body temperature, we subtract this from 37 degrees Celsius.
- 37 degrees Celsius - 2 to 2.5 degrees Celsius = 34.5 to 35 degrees Celsius.

6. **Select the Correct Option**: Based on the calculated optimal temperature range, the correct answer from the provided options is 34.5 to 35 degrees Celsius.

**Final Answer**: The optimal temperature for spermatogenesis is **34.5 to 35 degrees Celsius**.
