The uterus is a small organ in your abdominal cavity. It is the size of your fist and is shaped like a pear. The base of the uterus, also called the cervix, is located deep inside the vagina.

What does the uterus do?

A fertilized egg can grow into a baby in the uterus, and is usually delivered through the vagina 9 months later. If the egg hasn’t been fertilized, you have a period. Then blood from your uterus is discharged through your vagina. As long as no egg is fertilized, this is repeated once a month. Read more about your fertility cycle.

Feel it yourself

The cervix is at the base of the uterus. You can feel it yourself.

  • Go deep inside your vagina with your finger.
  • The cervix is at the top of your vaginal canal.
  • It will usually feel quite firm and not particularly sensitive, except when you’re ovulating.
  • A man may be able to feel the cervix during penetrative sex. As long as this doesn’t hurt either of you, it’s not a problem. If it does hurt, you could try another position.


You develop breasts during puberty. This could start in a girl of 8, but also in a girl of 14. Age varies for all girls.


During puberty, a girl has her first period. For about 5 days, some blood, mixed with mucus, flows from your vagina. You can use tampons, sanitary pads or cups to soak up the blood and mucus.
