Seminal vesicle is present at the junction of

Options

A. prostate and urethra
B. prostate and vas-deferens
C. prostate and cowper's gland
D. vas deferens and testis

Answer

**Step-by-Step Solution:**

1. **Understanding Seminal Vesicles**: The seminal vesicles are paired structures in the male reproductive system. They are also referred to as "uterus masculinus."

2. **Function of Seminal Vesicles**: These structures play a crucial role in the production of seminal fluid, contributing approximately 70% of the total volume of semen.

3. **Location of Seminal Vesicles**: The seminal vesicles are located behind the urinary bladder. This anatomical positioning is important for understanding their relationship with other reproductive organs.

4. **Identifying the Junction**: The question specifically asks for the junction where the seminal vesicles are located. The seminal vesicles connect with the vas deferens to form the ejaculatory duct.

5. **Final Answer**: Therefore, the seminal vesicles are present at the junction of the prostate gland and the vas deferens.

**Conclusion**: The most appropriate answer to the question is that the seminal vesicle is present at the junction of the prostate gland and vas deferens.
