Which structures are the supportive male glands?

• A. Seminal vesicles, bulbourethral glands, prostate gland
• B. Prostate gland
• C. Seminal vesicles
• D. Bulbourethral glands

Answer: (A)

Accessory male glands are the glands that secrete fluids to form semen and support sperm function, rather than the testes themselves. The complete set of these supportive glands includes the seminal vesicles, the prostate gland, and the bulbourethral (Cowper’s) glands. Seminal vesicles provide most of the seminal fluid, rich in fructose for energy and prostaglandins to help sperm movement. The prostate adds a fluid with enzymes and buffering capabilities that aids sperm viability in the female tract. The bulbourethral glands secrete clear mucus that lubricates the urethra and neutralizes any residual acidity, protecting sperm during ejaculation. Since the question asks for all the supportive glands, the full trio—seminal vesicles, prostate gland, and bulbourethral glands—is the best answer. Choosing only one of these omits the others, which is why the combined set is correct.
