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 identify the correct ones.

### Step-by-Step Solution:

1. **Statement I**: "The scrotum helps in maintaining the temperature ideal for spermatogenesis."
- **Analysis**: The scrotum is an external pouch that holds the testes. It is crucial for maintaining a temperature slightly lower than the body temperature, which is essential for the production of viable sperm.
- **Conclusion**: This statement is **correct**.

2. **Statement II**: "The male germ cells present in the seminiferous tubules undergo mitotic division and lead to the formation of sperms."
- **Analysis**: Male germ cells (spermatogonia) in the seminiferous tubules undergo **meiotic division** to form sperm cells (spermatids), not mitotic division.
- **Conclusion**: This statement is **incorrect**.

3. **Statement III**: "The bulbourethral glands secrete substances which help in lubricating the penis and these glands also help in the formation of the ejaculatory duct."
- **Analysis**: The bulbourethral glands (Cowper's glands) do secrete a pre-ejaculatory fluid that lubricates the urethra and aids in the passage of sperm. However, 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.
- **Conclusion**: This statement is **incorrect**.

4. **Statement IV**: "The site of spermatogenesis are highly compartments of the testis."
- **Analysis**: Spermatogenesis occurs in the seminiferous tubules of the testis, which are indeed highly compartmentalized structures.
- **Conclusion**: This statement is **correct**.

### Summary of Correct Statements:
- **Correct Statements**: I and IV
- **Incorrect Statements**: II and III

### Final Answer:
The correct statements about the male reproductive system are **I and IV**.
