Which gland secretes alkaline mucus in urethra to neutralise the acidity of urine?

Options

A. Prostrate gland
B. Cowper's gland
C. Seminal vesicles
D. preputial glands

Explanation

To solve the question "Which gland secretes alkaline mucus in the urethra to neutralize the acidity of urine?", we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Function of the Urethra**:
- The urethra serves as a common passage for urine and sperm in males. Before ejaculation, if a person has urinated, the urine in the urethra can be acidic.

2. **Understand the Need for Neutralization**:
- The acidity of urine can be harmful to sperm. Therefore, it is essential to neutralize this acidity to create a suitable environment for sperm.

3. **Identify the Gland Responsible for Neutralization**:
- The gland that plays a crucial role in neutralizing the acidity of urine in the urethra is the prostate gland. It secretes an alkaline fluid that helps to raise the pH level in the urethra.

4. **Consider Other Glands**:
- While there are other glands involved in male reproductive functions (like the seminal vesicles and bulbourethral glands), they do not primarily focus on neutralizing urine acidity. The seminal vesicles provide nourishment to sperm, and the bulbourethral glands (also known as Cowper's glands) secrete mucus for lubrication.

5. **Conclusion**:
- Based on the above points, the correct answer to the question is the prostate gland.

### Final Answer:
The gland that secretes alkaline mucus in the urethra to neutralize the acidity of urine is the **prostate gland**.
