Dr Jasdev Singh
Saline Infusion Sonography (SIS) & Tubal Patency Assessment
A gentle saline scan checks the inside of your womb and whether your fallopian tubes are open, two things that matter for conception.
Fertility Assessment
Checking your womb and tubes before you plan treatment
In SIS, a small amount of sterile salt water is passed into the womb during an ultrasound. The fluid outlines the lining, showing polyps, fibroids or scar tissue. A tubal patency test checks whether fluid flows freely through the fallopian tubes, where egg and sperm usually meet.
Many women worry this test will hurt. Most describe it as period like cramps that settle quickly.
Dr Jasdev explains the findings straight after the scan and what they mean for your plans.
A plan that starts with your results
Your age, history, test results and goals are reviewed before any treatment is suggested.
Clear reasons for each step
You will know why a test or medicine is recommended, what it can do and where its limits are.
Care that stays connected
Reviews are planned around how you respond, your cycle timing and your next decision.
What this test gives you
- A clear view of the womb lining without surgery
- Information on whether your tubes are open
- Guidance on whether surgery, IUI or IVF is the right path
How your care is planned
Every stage answers three questions: what is happening, why it matters, and what comes next. The plan is reviewed at each stage and adjusted when needed.
Review your history, symptoms and earlier scans
Book the test for the days after your period ends
Discuss the findings and next steps on the same day
How the test works
A speculum is placed, as in a smear test, and a thin tube is passed through the cervix. Saline is run in slowly while an internal ultrasound watches the womb and tubes. A foam fluid may be used to show the tubes more clearly. The test usually takes fifteen to twenty minutes.
Who may benefit
It is often part of a fertility assessment, especially before IUI or IVF. It is also helpful after miscarriage, abnormal bleeding, pelvic infection or surgery, or when a standard scan suggests a problem inside the womb.
What to expect
The test is done after your period ends and before ovulation, so there is no chance of an early pregnancy being affected. You can usually go home or back to work soon after. Light spotting and mild cramps for a day are common.

What women often ask about this test
Most couples arrive with several questions. These common ones can help you plan what to ask.
Will the test hurt?
What happens if a tube is blocked?
Can it be done on the same day as my scan?
Do I need antibiotics or pain relief?
Your questions about SIS and tubal testing
What is SIS?
Saline infusion sonography is an ultrasound scan with a little sterile salt water in the womb. It shows the lining clearly and can also check whether the tubes are open.
Who should consider it?
Women having fertility tests, those planning IUI or IVF, and anyone with symptoms or scan findings that suggest a problem inside the womb.
What tests are needed first?
A standard pelvic scan and infection screening are usually done first. A pregnancy test may be done on the day to be safe.
Is it painful or risky?
Most women feel cramping similar to a period, which eases quickly. Simple pain relief beforehand can help. Infection is uncommon, and you will be told which symptoms to watch for.
Why see Dr Jasdev for this test?
He explains the results in plain language and links them to your wider fertility plan, so you know what the findings mean for you.
How do I book?
Call or WhatsApp the clinic when your period starts, so the test can be timed for the days after it ends.
This page is general information and does not replace a consultation. Whether a treatment suits you, and its risks and timing, should be discussed with Dr Jasdev based on your own history.
