In male frog , Urinogenital duct receives

Options

A. sperms
B. urine
C. faecal matter
D. both 1 and 2

Explanation

### Step-by-Step Solution

1. **Understanding the Male Frog's Reproductive System**:
- The male frog has a specific reproductive system that includes the testes, kidneys, and associated ducts. The testes produce sperm, while the kidneys produce urine.

2. **Identifying Key Structures**:
- The testes are located on the upper surface of the kidneys. They are connected to a series of tubules called seminiferous tubules, where sperm is synthesized.

3. **Pathway of Sperm**:
- Sperm from the seminiferous tubules moves into the rete testis, then into the vasa efferentia, which connect to the kidneys through a canal known as Beder's canal.

4. **Combining Urine and Sperm**:
- The kidneys produce urine, and both the urine and sperm (now referred to as semen) are collected in the seminal vesicles.

5. **Formation of the Urinogenital Duct**:
- The seminal vesicles lead into the ureter, which in male frogs is called the urinogenital duct because it carries both urine and sperm.

6. **Final Pathway**:
- The urinogenital duct empties into the cloaca, where both urine and sperm are released into the surrounding water for external fertilization.

7. **Conclusion**:
- Therefore, the urinogenital duct in male frogs receives both sperm and urine.

### Final Answer
In male frogs, the urinogenital duct receives both sperm and urine.
