A sex gland which contributes fluid containing sugar fructose that provides spermatozoa energy for swimming and hormone prostaglandins that stimulate contractions in the female reproductive tract to aid sperm-ovum interaction is

Options

A. Cowper's gland
B. prostate gland
C. seminal vesicle
D. preputial gland.

Explanation

To solve the question regarding which sex gland contributes fluid containing sugar fructose and prostaglandins, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Function of the Gland**: The question specifies a gland that contributes a fluid containing fructose, which provides energy for spermatozoa, and prostaglandins, which stimulate contractions in the female reproductive tract.

2. **Consider the Options**: The options provided are:
- Cowper's gland
- Prostate gland
- Seminal vesicle
- Perpetual gland

3. **Analyze Each Option**:
- **Cowper's Gland**: This gland (also known as the bulbourethral gland) produces a lubricating fluid for the penis but does not primarily contribute fructose or prostaglandins.
- **Prostate Gland**: This gland contributes to the seminal fluid but does not specifically provide fructose or prostaglandins.
- **Seminal Vesicle**: This gland is known to produce a fluid rich in fructose and prostaglandins. It is located near the base of the bladder and its secretions help nourish sperm and facilitate their movement.
- **Perpetual Gland**: This option does not correspond to a known gland in human reproduction.

4. **Conclusion**: Based on the analysis, the gland that fits the description given in the question is the **seminal vesicle**.

5. **Final Answer**: The correct answer is the **seminal vesicle**.
