What is an HSG test - why do I need an HSG test?

An HSG test checks out your reproductive health in a very clever way. A pelvic ultrasound scan, together with a hormone test (e.g. FSH and LH), may not be enough to locate the cause of your infertility

Patients often have an HSG test to get a fuller picture of what’s going on. It often reduces the cost of IVF to make sure everything is clear first - IVF cost is not cheap – so it’s best to make sure everything is OK first. But many patients with infertility issues don’t have an HSG and still have successful pregnancies.

An HSG is an examination of your fallopian tubes and uterus. Dye is passed, via a catheter through your vagina, into your uterus, quickly filling it, the attached tubes and – usually indicating all is well – the abdominal cavity. The movement of the fluid is monitored by x-ray.

The ultimate purpose of an HSG is to find problems which can cause fertility problems and, in some cases, make conception and pregnancy impossible. Sperm and eggs need an optimal environment.

An HSG can sometimes solve a fertility problem there and then. If you have blockages in your tubes, the fluid occasionally moves them out the way.

An HSG is a little uncomfortable. It only takes 10 to 15 minutes. During and after the HSG, you may experience cramping. You’ll be given medication to counteract the low risk of pelvic infection, possibly an anti-inflammatory and perhaps even a sedative. An HSG is typically done after your bleed, but before ovulation. That way, everyone knows there’s not a pregnancy in there.
