Menstruation

When? Girls usually start to have their periods between 8 and 15 years old.

What? During a period, the lining of the uterus breaks down and a small amount of blood and cells passes out of the vagina. This is called menstruation.

New egg After a period, a new egg starts to develop in the ovary.

Thickening lining Whilst the egg is developing, the lining of the uterus starts to thicken with blood vessels and glands.

Freedom! When the egg is ready it is released from the ovary. This is called ovulation. ¡Estoy libre!

The journey The egg travels down the oviduct. It needs to be fertilised by a sperm within about 2 days Fertilisation occurs in the oviduct (if sperm are present)

Not fertilised? If the egg is not fertilised by a sperm it dies and is passed out of the vagina along with the uterus lining and we start again!

Fertilised If the egg is fertilised by a sperm the fertilised egg implants itself in the thick uterus. The woman is pregnant.
