Around after puberty: It depends on when a boy finishes puberty. A boy usually finishes puberty between 15 and 17 years old, with an average penile length of 6 inches. By the time a man reaches his 20's, the penis stops growing, which coincides when the person stops growing further in height also. Interestingly the penis tends to undergo an actual (and irreversible) reduction in size with > 60's.
