Hello. With all the talk and speculation about growth stunting during puberty because of an "imperfect" lifestyle, which normally means imperfect nutrition or not enough sleep, which is often talked about here, I wondered something else. Can this imperfect lifestyle affect your adult voice? Quite often I notice that while my dad, now in his late fifties, has a quite deep and "strong" voice, while mine is, well, not a "girl's voice", but certainly quite higher and kind of less "masculine". So I wondered if this could have to do with the lifestyle you live during your growth phase? Can imperfect diet, imperfect sleep and imperfect exercise during puberty not only affect your final height but also your adult voice, or is this aspect rather purely dependent on genetics?

Voice has to do with testosterone. Testosterone is known to accelerate the growth plates maturation... If you have low testosterone (and therefore a high estrogen/testosterone ratio) you should have had reached a highier final height. Also, testosterone according to medical literature is responsible for the length of your torso (this is why men with kleineftler syndrome are known to have really long limbs compared to their torso).
Sleep does not affect testosterone levels... Exercise and nutrition, only to a certain extent

I was under the impression that sleep did increase your testosterone levels..... How else would you explain morning wood?

Testosterone levels are at their highest in the morning when you first wake up..... I know that sleep induces HGH release, but haven't researched the effect that sleep has on testosterone.

So is that a yes or no to my initial question? Would my voice be lower if I had had better nutrition, done more sports, etc. in my teenage years?

Not to my knowledge... I was a couch potatoe during my teenage years yet I have a baritone voice

Another question, if this is the case, why are men taller than women? Men after all have much higher testosterone levels then women, so their growth plates should close faster than women's?
High testosterone signals your body to stop growing, because as you reach the last stage of puberty your testosterone levels increase.
That's partly why people who start puberty early typically don't grow quite as much as those who start later.
I was a couch potato as well, I have quite a deep baritone voice.
Exercise and so on, I think it all helps but it has quite a negligible effect, not enough to be worried about. We haven't stunted our growth, I used to think that but I read up on it (and I spent my late teens as a messed up druggy and in my early teens didn't eat enough). Stunted growth literally means you were malnourished or anorexic.

I just don't understand - if testosterone can accelerate growth plate maturation, why are men taller than women? Why are many high T men tall? The big American high school football players you can think of - square jaw, narrow eyes, built like a tank. Why are some of them 6'3'' and over, if their high T levels accelerate growth plates closing? Is it because testosterone isn't the only aspect influencing height?

The aromatase enzyme is responsible for converting excess testosterone to estrogen. Broscience, but I personally believe that this is one of the major ways in how height is "inherited." (An overractive aromatase enzyme that produces lots of estrogen, thus leading to early growth plate fusion).
What I've personally observed is that a lot of the "freakishly" tall people, over 6'1-6'2, have very long, low-T faces and odd body shapes.
And, again, anecdotally for me, the most "high-T" looking men I've observed have usually been 5'8'-5'9, very strong brow-ridges, jawlines, wide faces, etc...
And I think this is where the myth of "weightlifting" stunting height comes from. Young 13-14 year old guys lift weights -> generate lots of testosterone -> estrogen -> growth plates fuse. As well as the myth of "masturbation" (as high T guys are more frequent to fap, so someone who jacked off a lot probably thinks they fused their growth plates early).
I'm rambling at this point, but this is why I also think growth can be stunted by as much as 2-3 inches. Say you spend ages 13-16 not sleeping very well, so you don't produce much GH or IGF-1. Well guess what, your body doesn't gaf. It's still going to keep pumping out testosterone that will eventually turn into estrogen and close your growth plates. You could argue that testosterone would also lower if you don't get much sleep, but it's nowhere near as dramatic as the amount of HGH you would miss out on.
