What is an HSG?
HSG shows the shape of the inside of the uterus and whether the fallopian tubes are open. It is often part of fertility investigations.
A small amount of contrast (a liquid that shows up on X-ray) is passed gently through the cervix while X-ray pictures are taken.
Why doctors request it
- Difficulty conceiving
- Checking the tubes after surgery or treatment
- Assessing the uterus after repeated miscarriage

This is general information. Always follow your own doctor's advice.
What happens during the visit
You lie on the X-ray table. A speculum is placed, as for a smear test, and a thin tube is passed into the cervix.
Contrast is then passed through the tube while X-ray pictures are taken. You may feel cramping similar to period pain, which usually settles soon after.
Afterwards
- Light spotting and mild cramping for a day are common.
- Contact your doctor if you have a fever, heavy bleeding or severe pain.
Common questions
Is HSG painful?
Most women feel cramping similar to period pain for a few minutes. Ask your doctor whether you should take a painkiller beforehand.
Why does the day of my cycle matter?
The test has to be done at the right point in your cycle. Message us on the first day of your period and we will tell you the right day.
Can I go home straight away?
Yes. Most women rest briefly and then go home. You may want someone to come with you.
