Answer:
Explanation:
Girls
During puberty your ovaries get bigger and your body will start to produce two hormones - oestrogen and progesterone.
Oestrogen causes your breast to grow and helps your vagina, uterus and fallopian tubes to develop. It also makes you grow taller and also changes the way fat is stored on your body making your waist, hips and buttocks more obvious.
After puberty, oestrogen and progesterone control your menstrual cycle or period.
Boys
For young men, the hormone testosterone is the hormone that starts development from boy to man.
Testosterone is the major male sex hormone and it is produced in the testes.
Testosterone levels rise significantly during puberty. When levels are high enough, testosterone starts the production of sperm, causes the chest and shoulders to broaden and causes facial hair to grow.
