I am almost 13 . I have no armpit hairs , pubic hairs , and sperm . Have i hit puberty yet ? I've grown at least two inches in 2 months . I also want to know , if you have semen have you hit puberty yet ?
You could be just about to start puberty or in the early stages of it.
If you search for the Tanner puberty scale there is information on growth and development and there is a quiz you can take to see what stage you are in.
There is nothing to worry about what you are experiencing is common among boys your age and soon enough the changes you are hoping for will happen.
Everything is normal.
