Question:
Which of the following does NOT produce seminal plasma?
Which of the following does NOT produce seminal plasma?
Show Hint
The male accessory glands that produce seminal plasma are the Seminal vesicles, Prostate, and Bulbourethral glands. The epididymis and vas deferens are just structural ducts.

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept: Semen is composed of sperm cells suspended in a nutrient-rich liquid medium known as seminal plasma.
Step 2: Key Formula or Approach: Identify which of the listed structures are accessory glands (which secrete fluid) and which are merely ducts (for transport/storage).
Step 3: Detailed Explanation: Seminal plasma is the combined fluid secretion of the male accessory reproductive glands.
These active secreting glands include the paired seminal vesicles, the single prostate gland, and the paired bulbourethral (Cowper's) glands.
Their secretions are rich in fructose, calcium, and certain enzymes essential for sperm survival.
The epididymis is a highly coiled tube located along the posterior surface of the testis.
Its primary function is the temporary storage, functional maturation, and acquiring motility of the sperm, but it does NOT secrete the bulk fluid known as seminal plasma.
Step 4: Final Answer: Therefore, the Epididymis is the correct answer.
