Read the following statements about male reproductive system and identify the correct ones.
I . The scrotum helps in maintaining the temperature ideal for spermatogenesis . II. The male germ cells present in the seminiferous tubules undergo mitotic division and lead to the formation of sperms .
III . The bulbourethral glands secrete substances which help in lubricating the penis and these glands also help in formation of the ejaculatory duct.
IV. The site of spermatogenesis are highly compartments of the testis .

Options

A. I and II
B. I and IV
C. I , III and IV
D. I , II and IV

Answer

To solve the question regarding the statements about the male reproductive system, we will analyze each statement one by one to determine their correctness.

### Step-by-Step Solution:

1. **Statement I**: "The scrotum helps in maintaining the temperature ideal for spermatogenesis."
- **Analysis**: This statement is correct. The scrotum is an external pouch that holds the testes and helps regulate their temperature. Spermatogenesis occurs optimally at a temperature slightly lower than the normal body temperature (around 34°C, which is about 3°C lower than the body temperature of 37°C). This temperature regulation is crucial for the proper development of sperm.

2. **Statement II**: "The male germ cells present in the seminiferous tubules undergo mitotic division and lead to the formation of sperms."
- **Analysis**: This statement is incorrect. The male germ cells, specifically spermatogonia, undergo mitotic division to produce more spermatogonia. However, the actual formation of sperm (spermatogenesis) involves meiotic divisions, not mitotic divisions. The process of meiosis leads to the formation of haploid sperm cells from diploid germ cells.

3. **Statement III**: "The bulbourethral glands secrete substances which help in lubricating the penis and these glands also help in formation of the ejaculatory duct."
- **Analysis**: This statement is also incorrect. The bulbourethral glands (Cowper's glands) do secrete a lubricating fluid that helps in sexual intercourse, but they do not contribute to the formation of the ejaculatory duct. The ejaculatory duct is formed by the union of the vas deferens and the seminal vesicle duct.

4. **Statement IV**: "The site of spermatogenesis are highly compartmentalized compartments of the testis."
- **Analysis**: This statement is correct. The seminiferous tubules within the testes are indeed the sites of spermatogenesis and are structured in a highly organized manner, allowing for the development and maturation of sperm cells.

### Conclusion:
Based on the analysis:
- **Correct Statements**: I and IV
- **Incorrect Statements**: II and III

Thus, the correct answer is that statements I and IV are true.

### Final Answer:
The correct statements are I and IV.
