When does puberty end?

[geni]

Ok I heard lots about when it starts and what the signs are but what about the end? What signs are there and what is the general age at which it ends?

This is a serious question so to forstall the jokes "40" and "when you die" have already been said.

It's usually safe to assume that puberty's really run its course by age twenty. But, as I'm sure you realize, it's not exact. It's possible to have a late growth spurt that would be associated with puberty after age 20.

The second you get laid, puberty is over.

Very old and venerable joke:

Puberty ends at adultery.


Da-boom-TISH!

I would say that puberty ends when the hormones finaly slow down , I had a break in the acne only in my late thirties, good reseach question!
