If you are preparing for a saline sonogram, you may be feeling a mix of curiosity, nerves, and uncertainty.
That is completely understandable.
A saline sonogram, also called a saline infusion sonohysterogram or SIS, is a common diagnostic test used in fertility and gynecologic care. It gives your doctor a closer look at the inside of the uterus and can help identify issues that may not show clearly on a regular ultrasound.
This test may be recommended if you are:
Trying to conceive naturally
Preparing for IVF or IUI
Investigating irregular bleeding
Exploring possible causes of miscarriage
Checking for polyps, fibroids, scar tissue, or uterine abnormalities
Making sure the uterine cavity is ready before embryo transfer
The procedure itself is usually brief, but knowing what to ask beforehand can make a big difference.
When you understand why the test is being done, what your doctor is looking for, how to prepare, and what the results may mean, you can walk into the appointment feeling more informed and less overwhelmed.
Here are 9 important questions to ask before your saline sonogram.
Key Takeaways
A saline sonogram gives your provider a clearer look inside the uterine cavity.
It may help detect polyps, fibroids, scar tissue, uterine shape differences, or lining abnormalities.
Timing matters. The procedure is usually scheduled after your period ends but before ovulation.
Mild cramping or discomfort can happen, especially when the saline is introduced.
Asking the right questions can help you understand how this test fits into your fertility or treatment plan.
Always follow your provider’s instructions for preparation, medications, timing, and aftercare.

What Is a Saline Sonogram?
A saline sonogram is a specialized ultrasound that uses sterile saline to gently expand the uterine cavity.
During the procedure, a thin catheter is placed through the cervix. Sterile saline is then slowly introduced into the uterus while ultrasound imaging is performed.
The fluid helps separate the walls of the uterus so your provider can see the inside more clearly.
A saline sonogram may help identify:
Uterine polyps
Submucosal fibroids
Scar tissue or adhesions
Asherman’s syndrome
Uterine septum
Bicornuate uterus or other shape differences
Thickened or irregular endometrial lining
Other uterine cavity concerns
A regular ultrasound can show important information about the uterus and ovaries, but it may not always show subtle problems inside the uterine cavity.
That is why your provider may recommend a saline sonogram as the next step.

1. Why Am I Being Recommended a Saline Sonogram Instead of a Regular Ultrasound?
This is one of the best questions to ask first.
A standard pelvic ultrasound can be useful, but it may not always show small or subtle abnormalities inside the uterine cavity.
A saline sonogram gives a clearer view of the inside of the uterus.
Why This Matters
Your doctor may recommend a saline sonogram if they want to look more closely for:
Polyps
Fibroids that affect the uterine cavity
Scar tissue
Adhesions
Uterine shape differences
Lining abnormalities
Possible causes of implantation failure
Possible causes of miscarriage
Issues that could affect IVF or IUI planning
What to Ask
What did you see on my regular ultrasound that made you recommend this?
Are we checking for a specific concern?
Could this test change my fertility treatment plan?
Is this being done before IVF, IUI, or embryo transfer?
Would a regular ultrasound miss what you are looking for?

2. What Will You Be Looking for During the Procedure?
Understanding what your provider hopes to find can help you see how this test fits into your bigger fertility picture.
A saline sonogram is not just a random test.
It is usually done to answer a specific question about the uterus.
Your Provider May Be Evaluating For:
Endometrial polyps
Submucosal fibroids
Uterine septum
Congenital uterine anomalies
Scar tissue from a prior surgery, infection, or miscarriage
Endometrial lining abnormalities
Causes of abnormal bleeding
Possible factors affecting implantation
Why This Matters
Some uterine findings may affect conception, implantation, pregnancy loss risk, or embryo transfer planning.
For example, a polyp or fibroid that changes the uterine cavity may need to be treated before moving forward with fertility treatment.
What to Ask
What specific findings are we trying to rule out?
Could these findings affect implantation?
Could they affect miscarriage risk?
Would an abnormal result delay treatment?
Would I need surgery if something is found?
3. Will This Procedure Be Painful or Uncomfortable?
Many people feel nervous about discomfort before a saline sonogram.
The experience varies from person to person.
Some people describe it as mild cramping. Others find it more uncomfortable, especially when the catheter is placed or when the saline is introduced.
What It May Feel Like
You may feel:
Pressure from the speculum
A pinch or cramp when the catheter is placed
Menstrual-like cramping when saline enters the uterus
Pelvic fullness or pressure
Mild cramping after the procedure
Light spotting afterward
Why This Matters
Knowing what to expect can help you feel less caught off guard.
Your provider may recommend taking an over-the-counter pain reliever before the appointment, such as ibuprofen, if it is safe for you.
What to Ask
How uncomfortable is this procedure usually?
Should I take ibuprofen or another pain reliever before the appointment?
What dose do you recommend?
Should I avoid NSAIDs for any reason?
Can you pause if I need a break?
What symptoms are normal afterward?
4. Do I Need to Schedule This at a Certain Time in My Cycle?
Yes, timing usually matters.
A saline sonogram is often scheduled after your period ends but before ovulation.
This is commonly around cycle days 6 to 12, although your clinic may use a slightly different window.
Why This Timing Matters
The ideal timing helps ensure:
The uterine lining is thin enough for clear imaging
Your period has ended
You are unlikely to be pregnant
The provider can see the uterine cavity more clearly
Results are easier to interpret
What to Ask
What cycle days do you prefer for this test?
Should I call on cycle day 1 to schedule?
What if my cycles are irregular?
Should I avoid intercourse before the test?
Do I need a pregnancy test before the procedure?
What happens if I ovulate earlier than expected?

5. What Should I Do to Prepare for the Appointment?
Preparation is usually simple, but every clinic may have slightly different instructions.
It is best to ask ahead of time so you are not guessing the day of the procedure.
Your Provider May Recommend:
Taking a pain reliever before the appointment
Avoiding intercourse before the procedure
Bringing a sanitary pad
Arriving with an empty or partially full bladder, depending on instructions
Taking antibiotics in select cases
Avoiding certain medications, if advised
Confirming that you are not pregnant
Why This Matters
Knowing exactly what to do before the appointment can help reduce anxiety and prevent rescheduling.
What to Ask
Should I take pain medication before coming in?
Should I eat beforehand?
Should my bladder be full or empty?
Do I need antibiotics?
Should I stop any medications or supplements?
Should I bring a pad?
Can I drive myself home afterward?
6. Will This Procedure Affect My Fertility Treatment Timeline?
If you are preparing for IUI, IVF, embryo transfer, or another fertility treatment, this question is important.
A saline sonogram can sometimes confirm that everything looks good and allow you to move forward.
But if something is found, your timeline may change.
What Could Happen
Depending on the results, your doctor may recommend:
Moving forward with treatment
Monitoring only
Removing a polyp
Treating a fibroid
Evaluating scar tissue
Doing a hysteroscopy
Delaying transfer until the uterus is optimized
Ordering additional imaging or testing
Why This Matters
If you are already emotionally and financially preparing for treatment, it helps to understand possible outcomes before the test.
What to Ask
Can I still try to conceive this cycle?
Will this delay IUI or IVF?
Could this affect embryo transfer timing?
If something is found, how long would treatment or recovery take?
Could this procedure change my protocol?
Will I need follow-up before we move forward?
7. What Happens If You Find Something Abnormal?
It is natural to worry about what might happen if the test shows something unexpected.
But asking this question ahead of time can help you feel more prepared.
Possible Next Steps May Include:
Repeat imaging
MRI
Diagnostic hysteroscopy
Hysteroscopic polyp removal
Fibroid evaluation or removal
Scar tissue treatment
Additional bloodwork
Cycle delay
Treatment plan adjustment
Why This Matters
Not every finding requires immediate treatment.
Some findings are small and may only need monitoring.
Others may be more important if you are trying to conceive or preparing for IVF.
What to Ask
What findings would be considered significant?
Would a polyp need to be removed?
Would a fibroid need treatment before pregnancy?
Could scar tissue affect implantation?
Would I need hysteroscopy?
How would this affect my next cycle?
8. Will I Get the Results Immediately, or Do I Need a Follow-Up?
Some providers can explain the findings during or right after the procedure.
Others may review the images later and schedule a follow-up.
It depends on where the test is done and who performs it.
Results May Be Given:
During the procedure
Immediately afterward
Through the patient portal
By phone
At a follow-up appointment
After the physician reviews the images
Why This Matters
Waiting for results can be stressful.
Knowing when and how you will receive information helps you plan and reduces uncertainty.
What to Ask
Will you tell me what you see during the test?
Who reviews the images?
When will I get the official results?
Will results be posted in the portal?
Will I need a follow-up visit?
Who will explain what the findings mean for fertility?
9. How Will This Information Help Us Move Forward?
This may be the most important question.
A saline sonogram is most useful when the results guide a clear next step.
You want to understand how the information will be used in your care plan.
Possible Next Steps Could Include:
Trying naturally with more confidence
Moving forward with IUI
Moving forward with IVF
Proceeding with embryo transfer
Planning polyp removal
Planning fibroid treatment
Treating scar tissue
Ordering additional testing
Adjusting your timeline
Repeating imaging later
Why This Matters
This question helps turn the test from “one more thing to do” into a meaningful part of your fertility roadmap.
What to Ask
How will this test change our plan?
What result would allow us to move forward?
What result would delay treatment?
What result would require surgery?
What are the next steps after a normal result?
What are the next steps after an abnormal result?
