I want to know the answer to the following question:
Puberty causes what to happen in boys?
All the background I'm provided with is that "It is the stage of life characterized by the appearance and development of secondary sex characteristics (for example, a deeper voice and larger adam's apple in boys, and development of breasts and more curved and prominent hips in girls) and a strong shift in hormonal balance towards an adult state.". Is that enough to answer the question?
