Increase in temperature by `2^@C` scrotum would

Options

A. reduce the fertility by impairment of spermatogenesis
B. have no effect on fertility
C. reduces blood supply to scrotum
D. pull the tertes towards abdomen

Answer

To solve the question regarding the effect of an increase in temperature by 2°C on the scrotum, we can break down the reasoning step-by-step:

### Step-by-Step Solution:

1. **Understanding the Role of the Scrotum**:
- The scrotum is an external pouch that contains the testicles. Its primary function is to regulate the temperature of the testes, keeping them at an optimal temperature for sperm production.

2. **Optimal Temperature for Spermatogenesis**:
- The ideal temperature for spermatogenesis (the production of sperm) is approximately 35°C, which is about 3°C lower than the normal body temperature of 38°C. This lower temperature is crucial for the proper development and maturation of sperm cells.

3. **Effect of Increased Temperature**:
- An increase in temperature by 2°C (from 35°C to 37°C) can negatively impact spermatogenesis. Higher temperatures can impair the process of sperm development, leading to reduced fertility.

4. **Analyzing the Options**:
- **Option 1**: "Reduce the Fertility by the Impairment of Spermatogenesis" - This option is correct because increased temperature can indeed impair sperm production.
- **Option 2**: "Have no effect on fertility" - This is incorrect as increased temperature does affect fertility.
- **Option 3**: "Reduces blood supply to scrotum" - This is not directly related to the temperature increase.
- **Option 4**: "Pull the testis towards abdomen" - While the scrotum can move the testis, this is not a direct consequence of a temperature increase.

5. **Conclusion**:
- Therefore, the correct answer is **Option 1**: Increase in temperature by 2°C would reduce fertility by impairing spermatogenesis.
