In mammals , maturation of sperm take place at a temperature

Options

A. equal to that of body
B. higher than that of body
C. lower than that of body
D. at any temperature

Answer

To answer the question regarding the temperature at which sperm maturation occurs in mammals, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Spermatogenesis**:
- Spermatogenesis is the process of sperm production and maturation in males. It primarily occurs in the testes.

2. **Location of Maturation**:
- The maturation of sperm takes place in the epididymis, which is located on the surface of the testes.

3. **Temperature Requirements**:
- For proper sperm maturation, a lower temperature than the normal body temperature is required. The normal body temperature in humans is approximately 37 degrees Celsius.

4. **Optimal Temperature Range**:
- The optimal temperature for sperm maturation is typically 1 to 8 degrees Celsius lower than the normal body temperature. This means the ideal temperature range for sperm maturation is between 29 to 36 degrees Celsius.

5. **Reason for Lower Temperature**:
- The testes are located outside the abdominal cavity in the scrotum, which helps maintain this lower temperature. The scrotum has a thin outer covering with little insulating fat, allowing for effective cooling.

6. **Effects of Higher Temperatures**:
- Exposure to higher temperatures (such as from hot baths, saunas, or steam rooms) can negatively affect sperm production and viability.

7. **Conclusion**:
- Therefore, the correct answer to the question is that sperm maturation in mammals takes place at a temperature lower than that of the body.

### Final Answer:
- The maturation of sperm in mammals takes place at a temperature **lower than that of the body**.
