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

**Step-by-Step Solution:**

1. **Understanding the Male Reproductive System**: The male reproductive system consists of several structures that contribute to the production and transport of sperm. Key components include the testicles, epididymis, vas deferens, seminal vesicles, prostate gland, and Cowper's glands.

2. **Pathway of Sperm**: The pathway of sperm begins in the testicles where sperm is produced. From the testicles, sperm travels to the epididymis for maturation.

3. **Movement through the Vas Deferens**: After maturation in the epididymis, sperm moves into the vas deferens, which is a muscular tube that transports sperm to the ejaculatory duct.

4. **Secretion from Accessory Glands**: As sperm travels through the reproductive tract, it encounters several accessory glands that add secretions to the sperm. These include:
- Seminal vesicles
- Prostate gland
- Cowper's glands (bulbourethral glands)

5. **Identifying the First Gland**: The question asks which accessory reproductive gland's secretion is associated with sperm first. The seminal vesicles are the first glands that contribute secretions to the sperm after it leaves the epididymis.

6. **Conclusion**: Therefore, the correct answer is the seminal vesicle, as it is the first accessory gland that secretes fluid associated with sperm.

**Final Answer**: The first accessory reproductive gland's secretion associated with sperm is the **seminal vesicle**.
