Stopped

When is the end of puberty? Are there signs that puberty have stopped?:confused:

I guess you would notice it when you have gotten all the effects from puberty and it all stops or slows down over time

Firstly, you're only fifteen so you're likely right in the middle of puberty. Normally people finish puberty around 17-21 and you can tell when everything's settled down and nothing's changing anymore.

Thinking about the answer I can see the difficulty here because you have a set of changes, most of which are caused by an increase in testosterone, some of which have a definite end-point and some don't.

So, on the more definite things you could meassure testicle growth (as used in the tanner scale, those most people don't measure themselves), penis growing longer (also used in the tanner scale) and growth in height. By the end of puberty these should all have stopped. To me these seem like the most reliable things to look at.

It is tempting to consider hair growth. The tanner scale says you're on the last stage (five) when your public hair has spread to your thighs. I'd also expect some armpit hair and some sign of facial hair. Hair growth continues to be affected by testosterone for the rest of life, though, with many guys finding fuller beard growth and gradually spreading or thickening chest/body hair into their twenties and then after that maybe thinning or receding head hair. It's also hard to measure hair.

You could measure voice pitch to see if your voice has finished changing but ossification of the larynx continues well into adulthood and greater familiarity and practice can mean an older guy may be able to do more with his voice so again a bad measure.

You could measure muscle mass but this responds to exercise so it can go up and down depending on your routine. Another unreliable measure.

And, of course, you'd expect to be able to ejaculate by the end of puberty. We've had recent discussion about how, for most guys, semen volume starts out small and gets bigger as they develop so you could try measuring the volume to see when it stops increasing. The problem is volume also varies with other factors like time since last ejaculation and time spend aroused prior to orgasm etc. so spotting a definite point isn't easy.

There is an emotional side to puberty as well, all those fluctuating hormones mixing all about will definitely give you some wild mood swings and alter your brain chemistry/structure significantly. There really is a difference between a so-called "adult" brain and a teenager's, but there isn't much of a distinction and it's hard to measure emotion.

The guy above probably has the best answer concerning the physical changes, there's no real way of telling when it actually stops I'm afraid.
