HyCoSy & SIS PROCEDURES

State-of-the-art HyCoSy and Saline Infusion Sonography (SIS) designed for optimal clarity, high diagnostic accuracy, and patient safety.

What is HyCoSy?

HyCoSy checks the fallopian tubes are open by injecting a small amount of bubbly fluid (Exem foam) into the uterus through a thin tube (catheter) and observing it with ultrasound. The test is mainly used to investigate delay in falling pregnant, or in the lead-up to some fertility treatments. It is very similar to the radiology procedure known as HSG but does not use any radiation or iodine-based solutions (it is safe for people with an iodine allergy).

What is SIS?

SIS is a very similar procedure, but injects sterile salt water instead of Exem foam. It is used to outline the uterine cavity to check for its shape or the presence of polyps, fibroids or scarring.

Neither procedure should be performed if you are, or may be, pregnant at the time. They should also be delayed until following treatment of suspected or confirmed pelvic infection.

There is some discomfort associated with both procedures, similar to period pain. The intensity varies between different people but is not usually too painful. There is more pain when the catheter does not pass easily into the uterus. We strongly recommend that you take 2 tablets of an anti-inflammatory medication (such as Ponstan, Nurofen, Advil or Naprogesic) an hour before your appointment.

You must not have sexual intercourse from the first day of your period immediately before the procedure until after the procedure has been performed.

How do I make a booking?

Complete the HyCoSy/SIS booking form, available here, and submit.

The procedure should be done after the heavy days of bleeding have ended and at least 2 days before ovulation is expected.

If you have a predicable cycle, we will aim to offer you an appointment 1-2 months in advance. If you have an unpredictable cycle, arranging the timing can be more difficult. Contact our rooms if you have not heard from us with suggestions within 2 weeks of submitting your form.
