Some women are born with abnormalities in the shape, size or structure of the uterus. During the development of the female embryo, the  uterus is formed from two small tubes called Mullerian ducts. Around pregnancy week 10, these 2 tubes come together and fuse to form a single  uterine cavity.When the Mullerian ducts do not fuse at all or fuse incompletely, it can result in a uterine abnormality.

• bicornate uterus : ThIs type of uterus looks more like a heart  shape with a deep indentation at the top  instead of pear shape. It is called the uterus with two horns because of its  shape.
• unicornate uterus : This uterus is half the size of a uterus and has only one fallopian tube. This abnormality is rare .
