Female

In females the ovaries produce the hormone oestrogen and proyesterone.

These make female characteristics happen and are involved in the menstral cycle.

Progesterone maintains the lining of the womb - suppresses FSH production in the pituitary gland

Oestrogen controls puberty and the menstrual cycle in females; stimulates production of LH and suppresses the production of FSH in the pituitary gland

Male

Testes produce the hormone testosterone.

Testosterone makes male secondary sexual characteristics happen and controls puberty

What are they?

They are chemicals that act like messengers.

They are secreted by glands and carried form organ to organ by blood.

Glands associated with reproduction are called pituitary gland found at the base of the brain

Pituitary gland

The pituitary gland produces the follicle stimulating hormone (FSH) and the Luteining hormone (LH).

It also controls many other glands in the body.

The follicle stimulating hormone triggers egg ripening and Oestrogen production in ovaries

The Luteinising hormone triggers eggs release and progesterone production in ovaries
