A hysterosalpingogram (HSG) checks the shape of the uterus and whether the fallopian tubes are open. A thin catheter is passed through the cervix, similar to a cervical screening test, and a small amount of contrast is gently introduced while live X-ray pictures are taken.
It's commonly part of fertility investigations. Cramping, similar to period pain, is common during and shortly after the procedure. Some clinics offer a related ultrasound test (HyCoSy) instead.
Why your doctor might request an HSG
- Fertility investigations
- Checking the fallopian tubes after tubal surgery
- Assessing the shape of the uterus
- Recurrent miscarriage investigations
HSG: preparation, referral & Medicare
Preparing for your HSG
- The test is booked for a specific window in your cycle, usually after your period ends and before ovulation — contact the clinic on day one of your period
- Avoid unprotected intercourse from your period until the test, as advised by the clinic
- Take simple pain relief about an hour beforehand if the clinic recommends it
- Tell the clinic about iodine contrast allergies or pelvic infection
- Bring a sanitary pad for afterwards
How long it takes: About 30 minutes at the clinic; the procedure itself takes 10–15 minutes
Referral, Medicare & bulk billing
An HSG needs a referral, from a GP or a fertility or gynaecology specialist. With a valid referral it attracts a Medicare rebate; some clinics bulk bill and others charge a gap — it varies. The clinic will confirm billing and the right timing in your cycle. Booking through Radly sends a request, and the clinic confirms the time with you.
