Which accessory genital gland occurs only in mammalian male?

Options

A. Prostrate gland
B. Perineal gland
C. Cowper's gland
D. Bartholin gland

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for an accessory genital gland that is found only in male mammals. This means we need to identify a gland that is exclusive to the male reproductive system in mammals.

2. **Identifying Accessory Genital Glands**: Accessory genital glands in males include the prostate gland, seminal vesicles, bulbourethral (Cowper's) glands, and others. We need to evaluate which of these glands is specific to male mammals.

3. **Prostate Gland**: The prostate gland is an unpaired gland located just below the urinary bladder in males. It secretes an alkaline fluid rich in bicarbonate ions, which helps neutralize the acidity of the vaginal environment. This gland is indeed present in all male mammals.

4. **Cowper's Gland**: Also known as the bulbourethral gland, this gland is present in human males but is not exclusive to mammals as it can be found in other vertebrates as well.

5. **Perineal Gland**: The perineal gland is located in the brain and is not an accessory genital gland. It is not relevant to the question.

6. **Bartholin's Gland**: This gland is found in females and is responsible for secreting mucus to lubricate the vagina. Since the question is about male glands, this option is incorrect.

7. **Conclusion**: After evaluating the options, the only accessory genital gland that occurs exclusively in male mammals is the prostate gland. Therefore, the correct answer is the prostate gland.

**Final Answer**: The accessory genital gland that occurs only in mammalian males is the **prostate gland**.
