Which of the following structure of the female reproductive system can be taken as homologous to the scrotal sac of the male ?

Options

A. Mons pubis
B. Labia majora
C. Bulbourethral gland
D. Forchette

Answer

To determine which structure of the female reproductive system is homologous to the scrotal sac of the male, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Homologous Structures**:
- Homologous structures are those that have a similar embryonic origin but may serve different functions in adults. In this case, we are looking for a female structure that corresponds to the male scrotal sac.

2. **Identify the Function of the Scrotal Sac**:
- The scrotal sac is an external pouch that contains the testes and helps regulate their temperature for optimal sperm production.

3. **Consider the Female Reproductive Structures**:
- In the female reproductive system, we need to find a structure that is located externally and has a similar function to the scrotal sac.

4. **Evaluate the Options**:
- **Mons Pubis**: A cushion-like structure with pubic hair, not homologous to the scrotal sac.
- **Labia Majora**: These are the outer folds of skin that protect the female genitalia and are located externally. They are homologous to the scrotal sac.
- **Bulbar Urethral Gland**: This is not homologous to the scrotal sac; it corresponds to Bartholin's gland in females.
- **Fauchet**: This is not a recognized structure in this context.

5. **Conclusion**:
- The labia majora are homologous to the scrotal sac in males. Therefore, the correct answer is **Labia Majora**.

### Final Answer:
- The structure of the female reproductive system that can be taken as homologous to the scrotal sac of the male is **Labia Majora**.
