does the growth of adam's apple effect a persons height? I have heard it from lot of people that if a person has fully matured adam's apple his height stops growing is it true
No. The Adam's apple does not affect height. But our hormones do affect both.
Hormones (androgens) like testosterone produce secondary sexual characteristics, which includes, growth spurt and enlargement of larynx (voicebox, Adam's apple).
So that just means, when the Adam's apple has reached its own mature growth, the height also does end.
