What sshould be the prostate size in different ages?

The normal prostate size varies with age. In young men (ages 20-30), the prostate typically measures about 20-25 grams. By middle age (around 40-60 years), it may increase to 30-40 grams, and in older men (over 60), it can grow to 40-60 grams or more due to benign prostatic hyperplasia (BPH). It's important to note that individual variations exist, and prostate size alone isn't a definitive indicator of health.
