HSU – Tubal patency test (HSU)
Clarity about your fertility baseline
At Freya Fertility we offer a professional test of your fallopian tubes’ patency – a key part of fertility evaluation if you wish to get pregnant or plan fertility treatment.
What is HSU?
HSU stands for Hystero-Salpingo-Ultrasonography – a gentle examination where we use ultrasound and a small contrast liquid to check whether at least one fallopian tube is open and functional.
This is crucial in fertility diagnostics because the egg must travel through the tube to meet sperm — either in a natural pregnancy or in treatments such as IUI.
Who is the test relevant for?
Women with prior pelvic infections such as chlamydia or gonorrhea
Women who have had previous abdominal or pelvic surgery, where scar tissue may affect patency
Women with endometriosis
Couples or singles who want certainty about tubal passage before starting fertility treatment
What you get from the test
- A clear status on whether your fallopian tubes are open
- Knowledge to decide whether natural conception, IUI or IVF makes sense
- A plan for the next steps based on your result
- Documentation for treatment planning
- Peace of mind and clarity — we start with what matters most
- Professional guidance throughout the process

You will meet a dedicated team who takes your concerns seriously, and we communicate with clarity and honesty — you will always know what to expect.

Preparation for the test
Before the examination we recommend that you:
- Fill out our assessment form
- Submit any previous examinations or operation reports
- Take mild painkillers approx. one hour before the test (e.g. Paracetamol / Ibuprofen), as the test can cause light menstrual-like discomfort
- Have a recent negative chlamydia test before the procedure
The examination is brief and outpatient.
How it works – step by step
1. Booking
Schedule a time, typically early in your cycle (approx. day 5–10)
2. Preparation
Ensure negative chlamydia test and follow pre-exam instructions
3. The procedure
A thin plastic catheter is introduced into the uterus, contrast liquid is injected, and ultrasound checks tubal passage. The procedure takes about 5–10 minutes.
4. Result & follow-up
We review the result with you and plan possible next steps.

Frequently asked questions (FAQ)
Most experience only mild discomfort and possibly period-like cramping — duration 5–10 minutes.
Usually between cycle day 5 and 11 — after your period has ended but before ovulation.
We will review the result together and discuss what it means — and what treatment options you have.
The risk is very low. If you experience fever, pain or foul-smelling discharge after the test, contact us or your doctor immediately.
