Hormones and puberty

The pituitary gland produces hormones that make other glands produce hormones: 

• In women estrogen in the ovaries
• In men testosterone in the testes

Estrogen and Testosterone make secondary sexual characteristics appear.

Puberty

Hormones from the pituitary gland make many physical changes happen:

• Growth spurt
• Growth of hair: under arms and near sexual organs (pubic hair)
• Fertile
• Secondary sexual characteristics

Children are often slowly growing.

man - spermcells are being produced in the testes

woman - egg cells mature in the ovaries
