Answer

To determine which glands are classified as male accessory glands in humans, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the Options:**
The options given are:
- A. Seminal vesicle
- B. Prostate
- C. Testes
- D. Bulbourethral (Cowper's) gland

2. **Define Male Accessory Glands:**
Male accessory glands are those that contribute fluids to the semen and play a role in reproduction. The primary accessory glands in males include the seminal vesicles, prostate gland, and bulbourethral glands.

3. **Analyze Each Option:**
- **Option A: Seminal vesicle**
- The seminal vesicles are indeed male accessory glands. They produce a significant portion of the seminal fluid, which nourishes and helps transport sperm.

- **Option B: Prostate**
- The prostate gland is also a male accessory gland. It produces prostatic fluid, which is a component of semen and helps to nourish and transport sperm.

- **Option C: Testes**
- The testes are not classified as accessory glands; they are the primary male reproductive organs responsible for sperm production and hormone secretion (testosterone).

- **Option D: Bulbourethral gland (Cowper's gland)**
- The bulbourethral glands are paired glands that are also classified as male accessory glands. They produce a pre-ejaculatory fluid that helps lubricate the urethra.

4. **Conclusion:**
Based on the analysis:
- Options A (Seminal vesicle), B (Prostate), and D (Bulbourethral gland) are all male accessory glands.
- Option C (Testes) is not an accessory gland.

5. **Final Answer:**
The correct answer includes options A, B, and D.
