Question

What are the changes visible at the puberty in male and female human beings?

Answer 1

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.
