Final answer:
During puberty, males experience growth of the testes and scrotum due to increased testosterone levels. This is followed by the growth of secondary sex characteristics like facial hair and broadening of shoulders.
Step-by-step explanation:
During puberty in males, the testes begin to grow and are housed within the scrotum. This growth is typically the first physical sign of puberty, followed by the growth and pigmentation of the scrotum and the growth of the pen-is. The development of testes and scrotum occurs due to the increase in testosterone levels, which also stimulates the growth of secondary sex characteristics like facial hair and broadening of shoulders.
