You have been trying to conceive for months. Your gynaecologist just mentioned something called an HSG test, and you nodded, but inside, you are panicking. What even is this test? Will it hurt? What if they find something wrong?
Take a breath. The HSG test procedure might sound intimidating, but knowing what to expect helps. Let's look at what the test is and why your doctor recommends it.
A hysterosalpingography test, shortened to HSG, is an X-ray test that checks your uterus and fallopian tubes. Your doctor needs to see if your tubes are open or blocked, and if your uterus has the right shape. Why? Blocked tubes are one of the biggest reasons women cannot get pregnant. Sperm cannot reach the egg, or the fertilised egg cannot travel to your uterus. The HSG is an imaging test that uses a special dye to visualise your reproductive organs on the screen. It is not surgery.

You are getting this test because you are dealing with infertility. Maybe you have been trying for 6-12 months without success, have had miscarriages, or have pelvic pain. The HSG test for fertility helps your doctor figure out:
Are your tubes open or blocked?
Is your uterus shaped normally?
Do you have fibroids, polyps, or scar tissue?
If you are over 35, your doctor might recommend this after just 6 months of trying; time matters more as you get older.
Your doctor will schedule this between day 1 and day 14 of your cycle, after your period ends but before you ovulate. Why? Because there is zero chance you are pregnant. They cannot do the test if you might be pregnant, as X-rays could harm a developing baby.
About an hour beforehand, take a painkiller, such as paracetamol or ibuprofen. Don't skip this. It helps with cramping. Wear comfortable clothes. You will undress from the waist down, so a salwar kameez or a loose top with leggings works better than a sari. Can you drive yourself? Most women can, but bring your husband, mother, or friend if you are nervous.
You will lie on an X-ray table with your feet in stirrups, like a pelvic exam. They insert a speculum, clean your cervix, and then slide a thin catheter through your cervix into your uterus. You will feel pressure and cramping, like period cramps. Then they inject contrast dye through the catheter. This flows into your uterus and through your tubes. The radiologist watches on a screen as the dye moves. If your tubes are open, dye spills out into your pelvis. If blocked, it stops at the blockage. The whole thing takes 5-15 minutes, though it might feel longer when you are uncomfortable.

This is what you really want to know, right? The HSG test pain level varies hugely from woman to woman. Some women say it is just uncomfortable, like bad period cramps. Others find it quite painful. A few barely feel anything.
If your tubes are open, the dye flows through easily, and it hurts less. If your tubes are blocked or if you have scar tissue, the pressure of the dye trying to push through can cause sharp pain.
The cramping happens when they insert the catheter and when they inject the dye. It feels like intense period cramps or gas pains. Some women also feel a pulling sensation. The pain does not last long. Once they remove the catheter, the worst is over. You might have cramping for a few hours afterwards, but it fades.
Take that painkiller beforehand.
Do deep breathing during the procedure.
Ask the radiologist to go slowly.
Remember, it is quick; you just need to bear a few minutes of discomfort.
You can go home right away. You will have cramping for a few hours. The painkiller should help. You will also have sticky, brownish discharge from the leftover dye and blood. Wear a pad, not a tampon. This might last a day or two. Some women feel dizzy right after. Lie down if you need to. You can return to normal activities the next day. Your doctor might tell you to avoid intercourse for a few days.
The radiologist sends a report to your gynaecologist within a week.
Tubes are open: Great news. Your tubes are not the problem. Your doctor will investigate other causes.
Tubes are blocked: Your doctor will discuss laparoscopic surgery or fertility treatments like IVF.
Uterine problems found: Fibroids, polyps, or scar tissue might need treatment first.
Some women get pregnant right after an HSG, as the dye might flush out minor blockages.
HSG is safe. Serious problems happen in less than 1% of cases. Possible risks include pelvic infection (rare), allergic reaction to dye (very rare), and injury to the uterus (extremely rare). Call your doctor immediately if you have a fever, severe pain that gets worse, heavy bleeding, foul-smelling discharge, or vomiting.
What if Your Tubes are Blocked?
Don't panic. Blocked tubes don't mean you cannot have a baby. Your doctor might suggest a laparoscopy to fix the blockage, IVF (which bypasses the tubes), or further tests.

Getting fertility tests feels overwhelming. You are scared, hopeful, and worried about pain and results. But thousands of women go through HSG tests every day. Most find it manageable. The information you get is worth the temporary discomfort. This test is one step in your journey. Whether your tubes are open or blocked, you are taking a corrective action and can hope to see positive results very soon.
An HSG (hysterosalpingography) test is an X-ray procedure that checks your uterus and fallopian tubes for blockages or abnormalities. Doctors use it to diagnose causes of infertility, especially blocked fallopian tubes, which prevent sperm from reaching the egg or stop a fertilised egg from reaching the uterus. The HSG test also reveals uterine fibroids, polyps, scar tissue, or shape abnormalities. It is done when you have been trying to conceive without success, have had miscarriages, or have pelvic pain or irregular periods.
During a hysterosalpingography test, you lie on an X-ray table with your feet up. The doctor inserts a speculum, cleans the cervix, and passes a thin catheter through it into the uterus. Contrast dye is injected through the catheter while X-ray images are taken. The radiologist observes the dye moving through the uterus and fallopian tubes on a screen. If the tubes are open, the dye spills into the pelvic cavity; if they are blocked, the dye stops at the point of blockage. The entire procedure takes about 5 to 15 minutes.
The HSG test pain level varies between women. Most experience cramping similar to period cramps when the catheter is inserted and when dye is injected. Some find it mildly uncomfortable, while others find it quite painful, depending on whether the tubes are open or blocked. Pain is worse if tubes are blocked because the pressure of the dye trying to push through causes sharp cramping. The discomfort lasts only during the procedure, with cramping continuing for a few hours after. Taking painkillers an hour before helps reduce pain.
The HSG test procedure itself takes only 5-15 minutes from start to finish. However, plan for about 30-45 minutes total at the clinic, including paperwork, preparation, the actual test, and a short rest period afterwards. You will lie on the X-ray table while the doctor inserts the catheter, injects dye, and takes multiple X-ray images as dye flows through your reproductive organs. Though brief, it might feel longer if you are experiencing cramping. You can go home immediately after and resume normal activities the next day.
