Which one of the following is not a male accessory gland?

Options

A. Seminal vesicle
B. Ampulla
C. Prostate
D. bulbourethral glands

Explanation

To determine which option is not a male accessory gland, we can follow these steps:

### Step 1: Understand Male Accessory Glands
Male accessory glands are glands that produce secretions which provide nutrition to sperm, enhance their motility, and help in lubrication during intercourse. The main male accessory glands include:
- Seminal vesicles
- Prostate gland
- Bulbo-urethral glands

### Step 2: Analyze the Options
We are given four options to evaluate:
1. Seminal vesicle
2. Ampulla
3. Prostate gland
4. Bulbo-urethral gland

### Step 3: Identify the Glands
- **Seminal vesicle**: This is a male accessory gland that produces a significant portion of the seminal fluid.
- **Prostate gland**: This is also a male accessory gland that contributes to the fluid that nourishes and transports sperm.
- **Bulbo-urethral gland**: This gland produces a pre-ejaculatory fluid that helps in lubrication and is considered a male accessory gland.

### Step 4: Determine the Odd One Out
- **Ampulla**: This is not a male accessory gland; it is a part of the female reproductive system, specifically the oviduct (fallopian tube), located between the infundibulum and the isthmus.

### Conclusion
The option that is not a male accessory gland is **Ampulla**.
