The fluid secreted by seminal vesicle mixes with the sperm for the first-time in

Options

A. Urethra
B. Vas deferens
C. Vagina
D. Ejaculatory duct

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks where the fluid secreted by the seminal vesicle mixes with sperm for the first time. This is related to the male reproductive system.

2. **Identifying the Options**: The options provided are:
- Urethra
- Vas deferens
- Vagina
- Ejaculate

3. **Eliminating Incorrect Options**:
- **Vagina**: This option can be eliminated because it is part of the female reproductive system, not the male reproductive system.
- **Urethra**: This is the last part of the male reproductive system where semen is expelled, so it cannot be the location where the mixing occurs for the first time.

4. **Understanding the Role of Vas Deferens**: The sperm is transported from the testicles through the vas deferens. This duct carries sperm to the seminal vesicles.

5. **Mixing of Fluids**: The seminal vesicles secrete a fluid that contains proteins, enzymes, mucus, and nutrients like fructose. This fluid is mixed with sperm in the vas deferens.

6. **Identifying the Correct Answer**: Since the mixing of the seminal vesicle fluid with sperm occurs in the vas deferens, the correct answer is the **vas deferens**.

7. **Final Answer**: The fluid secreted by the seminal vesicle mixes with the sperm for the first time in the **vas deferens**.
