I am 15 barely 5 ft tall a high voice, no armpit or facial hair, no acne, next to no pimples How can I enduce growth? At 15 isn't it a pretty serious delay?
No, it's not serious. It's not even a concern.
Puberty in a male can start as late as 16 years of age.
Not all 15 year olds have armpit or facial hair. Your voice can change at any time during puberty. We ALL develop at different rates/times. Don't compare yourself to anyone else.
Hope it helps.
