HSG Test: Procedure, Cost, Pain & Results Explained

Quick answer

An HSG test (hysterosalpingography) is a short X-ray procedure that checks whether your fallopian tubes are open and whether the shape of your uterus is normal. A thin tube passes a contrast dye through the cervix while X-ray images are taken. It usually takes 5-15 minutes, causes mild to moderate cramping rather than severe pain, and is a common first step in investigating infertility.

Key facts at a glance:

What it checks: open (patent) fallopian tubes and the uterine cavity shape.

When: usually days 6-12 of your cycle, after your period and before ovulation.

Pain: mild to moderate cramping; a painkiller taken an hour before helps.

Time: about 5-15 minutes, as an outpatient.

Cost in India: roughly Rs 2,000-8,000, depending on city and centre.

Results: dye flowing freely from both tubes is normal; a blockage may need further treatment.

What is an HSG test (hysterosalpingography)?

A hysterosalpingography, almost always shortened to HSG test, is an X-ray examination of the uterus and fallopian tubes. A small amount of contrast dye is gently introduced through the cervix, and as it travels through the uterus and tubes, X-ray images show its path. If the dye flows through each tube and spills freely into the pelvic cavity, the tubes are patent (open). If the dye stops, it may point to a blockage.

The test gives a fertility specialist two pieces of information at once: whether sperm and egg have a clear path to meet, and whether the inside of the uterus is a healthy shape for an embryo to implant. That is why it is one of the most widely used investigations in a fertility work-up.

Why is an HSG test done?

An HSG test for infertility is recommended when a couple has been trying to conceive without success and the doctor needs to rule out a structural cause. Common reasons include difficulty conceiving after 12 months of trying (or 6 months if the woman is over 35), suspected blocked fallopian tubes (often after a pelvic infection or surgery), a history of recurrent miscarriage, suspected uterine abnormalities such as polyps, fibroids, adhesions or a septum, and preparation before treatments such as IUI, where open tubes are essential.

When in your cycle should you have an HSG test?

An HSG is usually scheduled in the first half of the menstrual cycle, typically between day 6 and day 12, after bleeding has stopped but before ovulation. This timing reduces the chance of an early pregnancy being present and gives the clearest images. The test is not done if there is any chance you are pregnant or if you have an active pelvic infection.

How to prepare for an HSG test

Schedule the test for the correct part of your cycle (days 6-12). Take an over-the-counter pain reliever, such as ibuprofen, about an hour before if your doctor agrees. Tell your doctor about any allergy to iodine or contrast dye, or any history of pelvic infection. Bring a sanitary pad, as light spotting afterwards is normal.

HSG test procedure: what actually happens?

The HSG test procedure is quick and done on an outpatient basis, so you go home the same day. You lie on an X-ray table, positioned as you would be for a routine pelvic exam. A speculum is inserted and the cervix is cleaned. A thin tube (cannula) is placed into the cervix. Contrast dye is slowly passed through the tube into the uterus and fallopian tubes. X-ray (fluoroscopy) images are taken as the dye moves and fills the tubes. The cannula and speculum are then removed. The whole process usually takes 5-15 minutes.

Is the HSG test painful?

This is the question most women ask, so let us answer it directly: the HSG test is usually not very painful. Most women feel cramping similar to period pain when the dye is passed, which settles within a few minutes to a few hours. A small number experience sharper, brief discomfort, especially if a tube is blocked. Taking a painkiller about an hour beforehand makes a real difference, and light spotting for a day or two afterwards is normal.

HSG test cost in India

The HSG test cost in India typically ranges from about Rs 2,000 to Rs 8,000, depending on the city, the diagnostic centre or hospital, and whether it is done in a standalone radiology unit or a fertility clinic. Larger metros and premium hospitals sit at the higher end. Because pricing varies widely, always confirm the current cost with your chosen centre and ask whether the radiologist's reporting fee is included.

Understanding your HSG test results

Your HSG test results describe both your tubes and your uterine cavity. With a normal result, the contrast dye fills the uterus, passes through both fallopian tubes, and spills freely into the pelvic cavity, which means the tubes are open and the uterine cavity looks normal in shape. If the dye stops partway, one or both fallopian tubes may be blocked; a blockage can be caused by previous infection, endometriosis or scar tissue, and depending on the location and cause, treatment may involve surgery or moving directly to IVF, which bypasses the tubes entirely. If only one tube is blocked and the other is open, natural conception is still possible, though it may take longer. The HSG can also reveal filling defects from polyps, fibroids, adhesions or a uterine septum, which may need a hysteroscopy to confirm and treat.

Are there any risks or side effects?

An HSG is considered very safe. Mild cramping and light spotting are the most common effects. Less common risks include a pelvic infection (rare), a brief allergic reaction to the contrast dye (rare), and a small amount of radiation exposure that is considered low. Contact your doctor if you develop fever, heavy bleeding, severe pain or foul-smelling discharge after the test.

Can an HSG test help you get pregnant?

Interestingly, yes, sometimes. Some studies have reported a modest, temporary rise in pregnancy rates in the months immediately after an HSG, thought to be linked to a mild flushing effect on the tubes, particularly with oil-based contrast. The HSG is a diagnostic test, not a treatment, so it should not be relied on to conceive, but a small bonus effect is possible.

What to do after your HSG results

An HSG answers an important question, but it is one piece of a larger picture that also includes hormone levels, ovarian reserve and a semen analysis for the male partner. Reading these reports together can feel overwhelming, which is exactly where gentle, unbiased guidance helps. Speaking with a counsellor before any big decision can bring clarity.

Frequently asked questions about the HSG test

Is the HSG test painful?

Most women feel cramping similar to period pain when the dye is passed, which usually settles within a few minutes to a few hours. It is generally not severe. Taking a painkiller about an hour before the test, with your doctor's approval, noticeably reduces the discomfort.

How much does an HSG test cost in India?

An HSG test in India usually costs between Rs 2,000 and Rs 8,000, depending on the city, the diagnostic centre and whether it is done at a hospital or fertility clinic. Always confirm the current price and ask whether the radiologist's reporting fee is included.

How long does an HSG test take?

The HSG procedure itself usually takes about 5 to 15 minutes and is done as an outpatient, so you go home the same day. Including preparation and a short rest afterwards, plan for roughly an hour at the centre.

When in the cycle is an HSG test done?

An HSG is usually scheduled between day 6 and day 12 of the menstrual cycle, after your period ends and before ovulation. This timing lowers the chance of an early pregnancy being present and gives the clearest images.

Can you get pregnant after an HSG test?

Yes. Some studies report a small, temporary increase in pregnancy rates in the months after an HSG, likely due to a mild flushing effect on the tubes. The HSG is a diagnostic test rather than a treatment, but this minor bonus effect is possible.

What happens if one fallopian tube is blocked?

If one tube is blocked but the other is open, natural conception is still possible, though it may take longer. Your specialist will consider your age, ovarian reserve and other findings before recommending whether to keep trying naturally, use IUI, or move toward IVF.

Is an HSG test safe?

An HSG is considered very safe. Mild cramping and light spotting are common, while infection or an allergic reaction to the contrast dye are rare. Radiation exposure is low. Contact your doctor if you develop fever, heavy bleeding or severe pain afterwards.

Key takeaways

An HSG test checks whether the fallopian tubes are open and the uterine cavity is normal. It is a short, outpatient X-ray procedure, usually done on days 6-12 of the cycle. Discomfort is usually mild cramping, and a painkiller beforehand helps. Typical cost in India is roughly Rs 2,000-8,000. Normal results show dye flowing freely from both tubes, while blockages may need surgery or IVF. The HSG is one part of a full fertility work-up, so interpret it alongside other tests, with guidance.
