Transmasc Height - is there anything I can do to become 5'11" or 6" tall?

Being tall is something that reserved for tall people. Inherited genetic makeup including height is better accepted than rejected.
Extending someone’s height is possible but is extremely complex and seldomly done except for those with extreme stature issues.
I don’t think any surgeon would consider such a procedure for someone who is 5‘6” regardless of gender.
In the United States women have an average height of 5’4” and men have an average height of 5’9”. Five feet and 6 inches puts you right in the middle of average height of men and women in North America which should be ideal.
