At what age does the human penis reach its maximum size and its length and girth stop increasing?
I'm wondering, at what age does the human penis reach its maximum size and its length and girth stop increasing?
The human penis typically reaches its full size and stops growing by early adulthood, around the age of 18 to 21 years old. However, there may still be minor changes in size and girth throughout a man's life due to factors such as weight gain or loss, or changes in hormone levels.
