Testes of Rabbit occur

Options

A. in scrotal sacs
B. on side of kidney
C. inside body
D. on either side of dorsal aorta

Answer

**Step-by-Step Solution:**

1. **Understanding the Location of Testes in Rabbits:**
- Testes in rabbits are located in the scrotal sacs. This is a common feature among many vertebrates.

2. **Importance of Scrotal Sacs:**
- The primary function of the scrotal sacs is to maintain an optimal temperature for sperm production. Sperm development requires a temperature that is lower than the body temperature.

3. **Developmental Aspect:**
- In rabbits, the testes descend into the scrotal sacs when the rabbit reaches the age of four to five months. This descent is crucial for proper spermatogenesis.

4. **Evaluating the Options:**
- **Option A: Scrotal sacs** - This is the correct answer as it aligns with the known anatomy of rabbits.
- **Option B: On the side of kidney** - This is incorrect; testes are not located here in rabbits.
- **Option C: Inside body** - This is also incorrect because internal location would not allow for the necessary temperature regulation for sperm formation.
- **Option D: On either side of dorsal aorta** - This option is incorrect as well, as it does not reflect the anatomical position of the testes in rabbits.

5. **Conclusion:**
- Based on the evaluation, the correct answer is that the testes of rabbits occur in the scrotal sacs.

**Final Answer:**
- The testes of rabbits occur in the scrotal sacs.
