Which of the following accessory reproductive gland's secretion associate with sperms firstly?

Options

A. Prostate
B. Seminal vesicle
C. Cowper's gland
D. Bartholin glands

Answer

To answer the question "Which of the following accessory reproductive gland's secretion associates with sperms firstly?", we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Context**: The question is about male reproductive anatomy, specifically focusing on accessory reproductive glands.

2. **List the Accessory Reproductive Glands**: The main accessory reproductive glands in males include:
- Seminal Vesicles
- Prostate Gland
- Bulbourethral Glands (Cowper's Glands)

3. **Understand the Function of Each Gland**:
- **Seminal Vesicles**: These glands contribute a significant portion of the fluid that makes up semen, providing nutrients (like glucose) that are essential for sperm motility.
- **Prostate Gland**: This gland adds additional fluid to semen, which helps in sperm activation and mobility.
- **Bulbourethral Glands (Cowper's Glands)**: These glands secrete a pre-ejaculatory fluid that helps lubricate the urethra.

4. **Determine Which Gland's Secretion Associates with Sperm First**:
- The seminal vesicles are the first accessory glands that the sperm come into contact with as they are produced in the testes and travel through the reproductive tract. The secretions from the seminal vesicles mix with the sperm to form semen.

5. **Conclusion**: The seminal vesicles are the accessory reproductive glands whose secretion first associates with sperm.

### Final Answer:
The correct answer is the **Seminal Vesicle**.
