Answer

To determine which of the following is not a part of the human male reproductive system, we need to understand the components of this system.

### Step-by-Step Solution:

1. **Identify the Components of the Male Reproductive System**:
- The human male reproductive system includes external genitalia, ducts, and glands.
- Key parts include the testis, seminal vesicles, epididymis, prostate gland, and penis.

2. **Understand the Function of Each Part**:
- The testis is responsible for sperm production and is located in the scrotum, which is part of the external genitalia.
- Seminal vesicles and epididymis play roles in storing and transporting sperm.

3. **Identify the Options Given**:
- The question presents various options, including the term "Oviducts."
- Oviducts, also known as fallopian tubes, are specifically part of the female reproductive system.

4. **Analyze the Role of Oviducts**:
- Oviducts are involved in the process of fertilization, where the sperm meets the egg. This is a function exclusive to the female reproductive system.

5. **Conclusion**:
- Since Oviducts are not part of the male reproductive system, we conclude that the correct answer to the question is **Oviducts**.

### Final Answer:
- **Oviducts** (Option B) is not a part of the human male reproductive system.
