How big is the prostate?

• A. Size of a grape
• B. Size of a walnut
• C. Size of a pea
• D. Size of a tennis ball

Answer: (B)

The normal adult prostate is typically described as the size of a walnut. In practical terms, it measures about 4 cm in length, roughly 3 cm in width, and weighs around 20–25 grams. It sits just below the bladder and encircles the proximal urethra, contributing secretions to semen. This walnut-size reference is standard for healthy anatomy; when the gland enlarges, as with benign prostatic hyperplasia, it can become noticeably larger and press on the urethra, leading to urinary symptoms. So walnut-sized is the best representation of a normal prostate. A grape or pea would be smaller than normal, and a tennis ball would be larger than typical for a healthy gland.
