If you are finding it difficult to get pregnant, your doctor will probably discuss your gynaelogical history with you. He or she might also discuss getting your womb examined, this is called an endometrial biopsy.
What is an endometrial biopsy?
The physical health of your womb is crucial to establishing a pregnancy. With each cycle the womb lining should thicken in preparation for nurturing a fertilised egg. Infections and other uterine abnomalities can interfere with this process and create a hostile environment for a developing embryo.
An endometrial biopsy is a relatively straightforward procedure where a sample of the lining of your womb is removed via a plastic catheter and suction for testing.
The test is very quick and shouldn't be painful, but it may be uncomfortable and the catheter can provoke uterine cramping.
