The testes in humans are situated outside the scrotum. The pupose served is for

Options

A. maintaining the scrotal temperature lower than the internal body temperature
B. escaping any possible compression by the vesceral organs
C. providing more space for the growth of epididymis
D. providing a secodary sexual feature for exhibiting the male sex.

Answer

### Step-by-Step Solution:

1. **Understanding the Location of Testes**: The testes in humans are located in the scrotum, which is an external pouch-like structure hanging outside the body.

2. **Purpose of External Location**: The primary reason for the testes being outside the body is to regulate temperature. Sperm production (spermatogenesis) requires a temperature that is lower than the normal internal body temperature.

3. **Normal Body Temperature**: The average internal body temperature is approximately 37 degrees Celsius. However, sperm production is optimal at a temperature slightly lower than this.

4. **Temperature Regulation**: The scrotum helps maintain a lower temperature for the testes, which is crucial for effective sperm production. If the testes were located inside the body, the higher internal temperature would negatively affect spermatogenesis.

5. **Conclusion**: Therefore, the main purpose of the testes being situated in the scrotum outside the body is to maintain a scrotal temperature that is lower than the internal body temperature, which is essential for the proper development of sperm.

### Final Answer:
The testes in humans are situated outside the scrotum primarily to maintain a lower temperature necessary for effective spermatogenesis.
