If you are looking for information about
hysterosalpingography (HSG), your doctor will probably have recommended it to assess the condition of your fallopian tubes and uterus. This test is key in fertility studies, and although it sounds complex, here I will explain everything clearly and with real experience so that you know exactly what to expect.
What is hysterosalpingography?
Hysterosalpingography is an imaging
test that uses X-rays and a contrast medium to visualise the shape of the uterus and check if the fallopian tubes are blocked. It is mainly used in women who are having difficulty getting pregnant, as a blockage in the
fallopian tubes can be a common cause of infertility.
What is this test for?
This test can detect problems such as:
- Obstruction in the fallopian tubes, which prevents the passage of the egg.
- Uterine abnormalities, such as polyps, fibroids or adhesions.
- Congenital uterine malformations that can affect fertility or increase the risk of miscarriage.
- To assess tubal patency after surgery or fertility treatment.
Important: Although hysterosalpingography helps to diagnose problems, it does not treat them. If an obstruction is detected, the
doctor will recommend other procedures to correct it. If you have never had this test, it is normal to feel uncertain. Here is what the procedure is like:
Before the exam- It is scheduled in the first 10 days of the menstrual cycle (but after your period ends).
- It may be necessary to take an anti-inflammatory or antibiotics before the test.
- It does not require anaesthesia.
During the test ‘When my gynaecologist told me I needed a hysterosalpingogram, I was worried about the pain. He explained that it would only last a few minutes and that reassured me. On the day of the test, I arrived a little nervous, but the doctor explained each step to me.
- You lie on a stretcher with your legs in the gynaecological position.
- A speculum is placed (as in a smear test).
- A catheter is inserted into the uterus, through which the contrast medium will pass.
- The contrast fluid enters the tubes, allowing the doctor to see if they are blocked.
- X-ray images are taken.
‘When the fluid passed through my tubes, I felt a slight cramp, similar to menstruation, but it was bearable and lasted only a few seconds. Then the doctor removed the catheter and let me rest for a few minutes.’
After the test- There may be slight bleeding and discomfort such as cramps.
- It is recommended to use a sanitary towel (not tampons) in case there are any traces of the contrast medium.
- In some cases, the doctor may prescribe antibiotics to prevent infection.
Interesting fact: Some women manage to get pregnant after hysterosalpingography, as the contrast fluid can ‘clear’ small obstructions.
Does hysterosalpingography hurt?
The most common question is about pain. The answer varies for each woman.
- Some feel only mild discomfort.
- Others describe moderate pain, like severe menstrual cramps.
- In rare cases, it can be more painful if there are obstructions.
‘In my case, I felt pressure when the catheter was inserted and slight cramps when the fluid passed through my tubes. But the test was quick and totally bearable.’ Tip: If you are afraid of pain, you can take an ibuprofen one hour before the test to reduce discomfort.
Results of the hysterosalpingography
The radiologist will interpret the images and send a report to the gynaecologist. There are three possible results:
- Normal: The contrast medium passes through the tubes without any problems and the uterus is normal in shape.
- Tubal obstruction: If the fluid does not pass, there may be an obstruction in one or both tubes.
- Uterine abnormalities: Polyps, fibroids or malformations can be detected.
‘In my case, the result was normal, which gave me peace of mind and allowed me to move forward with my pregnancy plan.”
Side effects and risks
Hysterosalpingography is safe, but like any procedure, it can have side effects:
- Mild or moderate cramping.
- Slight bleeding for 1-2 days.
- Feeling dizzy or nauseous.
- Very rare: infection or allergic reaction to the contrast.
If you have a fever, severe pain or foul-smelling discharge after the test, contact your doctor.
What to do after the test?
After the hysterosalpingography, follow these tips:
- Rest if you feel discomfort.
- Drink water to eliminate the contrast medium.
- Do not have sex for 24-48 hours.
- If you have any questions, consult your gynaecologist.
Frequently asked questions
