Is stage 2 mostly hidden changes?

Is stage 2 mostly just hidden changes like the testicles increasing and pubic hair or will I also change from the outside?


Technically, pubic hair is an external change, it is just hidden by your clothing. However, there are other external changes. During stage 2, your hands and feet increase in size — sometimes dramatically. Then during stage 3 your arms and legs lengthen, which is what causes the growth spurt. Finally, the spine lengthens which isn’t as dramatic, but it does add a few inches and the shoulders widen.

Your growth spurt in stage 3 typically occurs 1.5 years after your peak rise in shoe size [Iris Busscher, “The value of shoe size for prediction of the timing of the pubertal growth spurt,” Scoliosis 20 January 2011].
