Question

in our body which hormones are secreted and from where when a boy see a girl?​

Answer 1

Testosterone stimulates the production of sperm, and is also responsible for the voice change in boys. The two hormones released by the brain work differently in girls. They signal the ovaries to produce the female sex hormones, estrogen and progesterone.

Answer 2

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.
