What is HSG?

Hysterosalpingography (HSG) is an advanced X-ray procedure that helps evaluate a woman’s reproductive health by examining the uterus and fallopian tubes. It is one of the first-line tests performed in infertility evaluation to detect abnormalities that may prevent natural conception.

Why is it Done?

• Timing of the Test –The procedure is usually scheduled between day 7–10 of the menstrual cycle (after bleeding ends but before ovulation).
• Preparation –A mild pain reliever or antibiotic may be prescribed before the test.
• Insertion of Catheter –A thin, flexible tube (catheter) is inserted through the cervix into the uterus.
• Injection of Contrast Dye –A special iodine-based dye is introduced into the uterine cavity.
• X-Ray Imaging –Continuous X-ray images are taken to track the dye as it fills the uterus and flows into the fallopian tubes.
• Observation –If the dye passes freely into the abdominal cavity, the fallopian tubes are open; if not, a blockage or abnormality is suspected.

Risks and Side Effects of HSG:

While HSG is generally safe, some women may experience:
* Mild Cramping or Discomfort during and after the test
* Light Vaginal Spotting for 1–2 days
* Infection (Rare) if bacteria enter the uterus or tubes
* Allergic Reaction to the contrast dye (very rare)
Most side effects are mild and temporary. Serious complications are uncommon when the procedure is performed under proper medical care.

HSG (Hysterosalpingography) – FAQ

Q1. What is an HSG test used for?

HSG is used to check whether the fallopian tubes are open or blocked and to evaluate the shape and condition of the uterus, which are important factors in infertility.

Q2. Is the HSG test painful?

Some women may experience mild to moderate cramping, similar to period pain, during the procedure. The discomfort usually lasts only a few minutes and can be managed with pain relief if needed.

Q3. When is the best time to do an HSG?

The test is typically scheduled between day 7–10 of the menstrual cycle, after menstruation ends but before ovulation, to ensure that there is no pregnancy and the uterine lining is thin for clear imaging.

Q4. How long does the HSG procedure take?

The entire procedure usually takes 15–30 minutes and is done as an outpatient test.

Q5. Are there any risks associated with HSG?

The procedure is generally safe. Rare risks include infection, allergic reaction to the dye, or very mild uterine injury. Most women experience only temporary cramping or light spotting.

Q6. Can HSG improve fertility?

Yes, in some cases, the flushing effect of the dye can help remove small blockages in the fallopian tubes, which may improve the chances of natural conception.
