Hysterosalpingogram, commonly abbreviated as HSG, is a specialized X-ray procedure used for examining a woman's uterus and fallopian tubes. It is primarily employed to investigate the causes of infertility and is also sometimes used to screen for uterine abnormalities. The test involves the injection of a contrast material into the uterine cavity to make the uterus and fallopian tubes visible on X-ray images.

HSG is a diagnostic tool that is especially valuable for assessing tubal patency, which means it can help to determine if the fallopian tubes are open or blocked. Furthermore, it can also provide information on the shape and structure of the uterus, which can be crucial for understanding various reproductive issues.
Women who experience difficulties becoming pregnant or who have had recurrent miscarriages might be recommended to undergo an HSG. It’s a relatively short procedure, usually taking no more than 30 minutes, and is typically performed in a radiology department at a hospital or clinic.
Scheduling: The procedure is usually scheduled after menstrual bleeding has ended but before ovulation, typically between days 5 and 12 of the menstrual cycle.
Medications: Inform your doctor if you are taking any medications, especially blood thinners or NSAIDs. Your doctor may prescribe antibiotics or advise you to take an over-the-counter pain reliever before the procedure.
Allergies: Tell your doctor if you have a known allergy to iodine or contrast materials.
Pregnancy: It is crucial to ensure you are not pregnant before undergoing an HSG, as the procedure is not safe during pregnancy. Inform your doctor if there is a possibility you could be pregnant.
Clothing: You will be asked to wear a hospital gown and to remove any metal objects.
You will lie on an examination table, usually in a position similar to that for a pelvic exam.
A speculum will be inserted into your vagina, and your cervix will be cleaned.
A thin tube called a cannula will be inserted into the opening of your cervix.
A contrast material will be injected through the cannula into your uterus and fallopian tubes.
X-ray images will be taken to observe how the contrast material moves through the uterus and tubes.
The speculum is removed at the end of the procedure.
You may experience some cramping, spotting, or mild pain, similar to menstrual cramps.
Avoid using tampons and refrain from sexual intercourse for 2-3 days after the procedure, or as advised by your doctor.
Consult your doctor if you experience severe pain, fever, or heavy bleeding.
HSG can provide detailed information about the shape and structure of the uterus and fallopian tubes. It is used primarily to assess if the fallopian tubes are open or blocked, which is crucial for fertility.
Some women might experience mild to moderate cramping during the procedure. Your doctor may recommend taking a pain reliever before the procedure to minimize discomfort.
There are minimal risks associated with HSG, such as allergic reaction to the contrast material, infection, or injury to the uterus. It’s important to discuss any concerns with your doctor before the procedure.
If you experience severe pain, fever, or heavy bleeding after the procedure, it is important to contact your doctor as soon as possible, as these could be signs of an infection or complication.
The results of an HSG are usually available within a few days after the procedure.
Most women are able to resume normal activities the day after the procedure. However, it’s important to avoid strenuous activity and follow any instructions provided by your healthcare professional.
There is some evidence to suggest that fertility can be temporarily improved for a few months after an HSG procedure, possibly due to the flushing effect of the contrast material.
Follow any instructions provided by your doctor, such as taking prescribed antibiotics, avoiding certain medications, and scheduling the procedure at the appropriate time in your menstrual cycle.
If your HSG shows that your fallopian tubes are blocked, your doctor will discuss the results with you and may recommend additional tests or procedures.
In case of abnormal findings, you should consult the gynecologist or fertility specialist who referred you for the HSG.
HSG is a valuable diagnostic tool for evaluating the health of the uterus and fallopian tubes, especially in the context of infertility. By being well-informed and following your doctor's instructions, you can make the experience as smooth as possible.
