At Midwest Fertility Center https://mfcfamily.com/, we believe that informed patients are empowered patients. If you’re undergoing a fertility evaluation, you may have been told you need an imaging test like a Hysterosalpingogram (HSG) or a Sono HSG (Saline Infusion Sonohysterography). While both tests help assess the uterus and fallopian tubes, they are quite different in how they work and what they reveal.
Here’s a simple guide to help you understand the differences—and how we at Midwest Fertility Center https://mfcfamily.com/ use them to support your journey toward parenthood.
What Is a Hysterosalpingogram (HSG)?
An HSG is an X-ray procedure that shows whether your fallopian tubes are open and if the uterus has a normal shape.
How It Works:
- A thin catheter is placed through the cervix.
- An iodine-based dye is gently injected into the uterus.
- Using fluoroscopy (a type of continuous X-ray), we track the dye to see if it flows through the fallopian tubes and into the pelvic cavity.
Why We Use It:
- To check if the fallopian tubes are open
- To assess for abnormalities in the uterus like fibroids, polyps, or scar tissue
Things to Know:
- Uses X-ray and iodine contrast dye
- Can cause mild cramping or discomfort
- Typically takes 10–15 minutes
- Performed in-office or at a nearby imaging center with radiology support
What Is a Sono HSG (Saline Infusion Sonohysterography)?
A Sono HSG, or saline sonogram, uses ultrasound and sterile saline to visualize the inside of the uterus. At Midwest Fertility Center, we also offer contrast-enhanced Sono HSG, which uses air bubbles or special contrast to evaluate fallopian tube openness.
How It Works:
- A small catheter is inserted into the uterus.
- Sterile saline (and sometimes air or contrast) is gently infused.
- A transvaginal ultrasound is performed to view the uterine cavity and, in some cases, fallopian tubes.
Why We Use It:
- To get a clear picture of the uterus, especially for detecting polyps, fibroids, adhesions, or septum
- In some cases, to check if fallopian tubes are open (with contrast-enhanced version)
Things to Know:
- No radiation exposure
- Generally well-tolerated
- Offers better detail of uterine lining
- Done right in our office by your care team

Which Test Is Right for You?
At Midwest Fertility Center https://mfcfamily.com/, we tailor every evaluation to your unique situation:
- If your provider needs to confirm if your tubes are open, especially before IUI or IVF, an HSG may be recommended.
- If you have irregular bleeding, recurrent miscarriage, or suspected uterine abnormalities, a Sono HSG can offer detailed insights—often with more comfort.
In some cases, both tests may be recommended at different stages to give us a complete picture of your reproductive health.
