What to expect during a sonohysterogram for fertility assessment

A sonohysterogram is an ultrasound-based fertility assessment of the uterine cavity and, in some protocols, the patency of the fallopian tubes. It uses sterile saline passed through the cervix rather than the X-ray dye used in a hysterosalpingogram. The scan can help a fertility specialist assess whether the cavity is ready for conception or embryo transfer and whether any treatment is needed first.

Most people find the procedure brief and tolerable, although cramping can be uncomfortable. Knowing what happens before, during and afterwards makes the appointment easier, particularly when timing must fit a menstrual cycle or an IVF schedule. This guide explains the process for people in Australia and those considering fertility care at a clinic overseas, including what to ask a GP, specialist or international fertility team.

What a sonohysterogram assesses

During saline infusion sonography (SIS), a clinician introduces a small amount of sterile saline through a thin catheter at the cervical opening. The fluid gently opens the uterine cavity so its shape and lining can be examined on ultrasound. This provides more detail than a routine pelvic scan and can reveal polyps, small fibroids that distort the cavity, adhesions, septa or an irregular endometrial surface. It may also show whether saline passes freely through the tubes when a tubal patency assessment is included.

The information helps explain abnormal periods, recurrent pregnancy loss or difficulty conceiving, and it can guide decisions about hysteroscopy, surgery or IVF preparation. It does not assess every cause of infertility. Ovarian reserve, hormone patterns, ovulation and sperm quality need separate evaluation, while conditions such as deeply infiltrating endometriosis may require other imaging. The procedure is also distinct from hysteroscopy, which uses a scope and may treat findings, and from HSG, which involves radiation.

Preparing for your appointment

Your GP or fertility specialist can arrange a referral and explain why the scan is needed. For a diagnostic saline study, the best timing is commonly after menstruation has finished and before ovulation, often between cycle days 2 and 9. If you are taking ovulation medication or starting IVF, the clinic may want a different cycle or a scan alongside another appointment. Do not arrange travel or work commitments until the timing instruction is confirmed.

Tell the clinic about pregnancy possibility, previous cervical surgery, pelvic infection, fibroids, an IUD, allergies and every prescribed medicine, supplement or blood thinner. Do not stop any medicine without advice. Follow the clinic’s preparation instructions; these may include avoiding vaginal douching or intercourse for a short period beforehand. Antibiotics are not routinely needed for this procedure and should only be used when the treating team recommends them. A pregnancy test may be requested, and the procedure is usually postponed if you are pregnant.

In major cities such as Sydney, Melbourne and Brisbane, private imaging and fertility clinics often sit in busy medical precincts with paid parking. Allow extra time for traffic, parking and finding the correct floor. Medicare rebates cover some assisted reproduction items, but a sonohysterogram is not automatically Medicare-funded; private health extras and the clinic’s billing policies determine the likely cost. Ask for an itemised estimate and a referral before booking.

What happens during the scan

On arrival, the clinician reviews the referral, confirms consent and explains the steps. You will usually lie back with your legs supported, sometimes with a pillow under your hips. A transvaginal ultrasound probe, covered with a sterile sheath and gel, is placed gently in the vagina. The screen allows you to see parts of the scan if you wish. A small catheter is then passed through the cervix, and saline is introduced slowly.

The fluid may produce period-like cramps, pelvic pressure, a feeling of fullness or a sudden gush of leakage as it drains. Some people feel dizzy or nauseated, especially if they have not eaten, although the scan is usually completed in about 5 to 15 minutes. Tell the staff immediately if pain becomes severe or you feel faint; they can pause, adjust the probe or stop. Pain relief can be discussed beforehand, and sedation is generally unnecessary.

An abdominal scan may be used first or afterwards to view the uterus and ovaries from above. If the operator is also checking tubal patency, the movement of saline through the tubes may be observed, although this component is not performed in every sonohysterogram. There is no radiation involved. Infection is uncommon, and serious complications are rare, but the small risks of infection, cervical irritation or injury should be reviewed with your clinician rather than assumed to be zero.

After the procedure

Afterwards, the catheter is removed and you can usually leave straight away. Cramping commonly settles within a few hours, although it can linger for a day or two. A small amount of spotting or watery discharge may occur for several days as fluid and cervical irritation resolve. Wear a panty liner, avoid tampons for the first 24 to 48 hours, and follow the clinic’s advice about intercourse, swimming and vigorous exercise.

Most people resume normal activity without special recovery measures, and routine antibiotics or a day of bed rest are not usually necessary. Contact the clinic for heavy bleeding, worsening pain, fever, foul-smelling discharge or a positive pregnancy test; urgent assessment is appropriate for severe symptoms. If another fertility procedure is planned, the team may prefer to wait until the uterine lining has settled and any bleeding has stopped, then review the scan before proceeding.

Understanding the results

Ask how and when the report will be available, whether you can receive both the written findings and the images, and how the results will be shared with your GP or IVF team. A clear report may describe the endometrial lining, cavity shape, any lesions and whether the tubes were assessed. A normal cavity is reassuring, but it cannot explain every fertility problem or guarantee implantation. Occasionally a repeat scan is needed if the views were limited or the timing was unsuitable.

If a polyp, adhesion, septa or cavity-distorting fibroid is found, the specialist may recommend hysteroscopy, further imaging or treatment before IVF. The appropriate choice depends on the finding, your symptoms and your treatment goals. Vitamin D status may also be reviewed in some fertility work-ups. Australia’s sun-protection habits and indoor work patterns mean deficiency can occur in people with limited exposure; the clinic’s overview of vitamin D and fertility is useful background, not a reason to order or supplement vitamin D without medical advice.

Its place in a fertility work-up

A cavity scan answers only one part of fertility assessment. Your clinician may also review ovulation, ovarian reserve and thyroid or prolactin symptoms, with blood tests such as AMH, FSH and estradiol chosen for the relevant question. AMH gives an estimate of ovarian reserve; it does not measure egg quality or predict natural conception on its own. Cycle timing matters, particularly for FSH and estradiol, so the blood test and scan should be organised together rather than booked randomly.

The partner’s semen analysis is an essential part of the work-up and should not be overlooked. Hormone blood tests may be added if the semen result, symptoms or examination suggest a male factor. This overview of male hormone testing explains the roles of testosterone and FSH and when they may be relevant. Results need interpretation alongside clinical findings, and privately bought “fertility test packages” can miss the context needed for a sound assessment.

Choosing a clinic and planning care

In Australia, fertility clinics operate under state and territory assisted reproduction legislation and the relevant health regulator, with consent, donor-conception and record-keeping rules that vary by jurisdiction. Ask who will perform the scan, how the clinic manages infection control, what happens to records and how results will inform treatment. Request pregnancy and live-birth figures appropriate to your age and treatment type, rather than relying on a general success percentage.

Any commercial promise deserves verification rather than acceptance at face value. This examination of a gambling site bet offers a useful parallel: identify the operator, read the terms and seek evidence behind headline claims. The same approach applies to overseas fertility packages, particularly discounted treatment bundles. Fertility outcomes vary with age, diagnosis and previous treatment, so transparent information about inclusions, exclusions and refund policies is more useful than a guaranteed result.

For patients travelling from Melbourne, Sydney or Brisbane to Mumbai, coordination is as important as the scan itself. Confirm appointments, medical visa requirements, medication supplies, cost estimates and plans for follow-up or unexpected complications in a written care plan. Donor eggs, surrogacy and parentage also involve law specific to where treatment and birth occur. Queensland is the only Australian jurisdiction with a framework for approved altruistic surrogacy, while intended parents elsewhere need specialist legal advice before committing to care abroad.

If a sonohysterogram has been recommended, book it with a team that can explain its purpose, interpret the findings and connect them to your wider fertility plan. Indo Nippon IVF in Mumbai provides specialist fertility care, advanced laboratory facilities and customised treatment planning for patients from India and overseas. Discuss whether ultrasound, blood tests and partner assessment should occur in one coordinated pathway. Depending on the findings and your goals, the team can discuss options such as Mini IVF, ICSI, donor egg IVF, egg freezing or preimplantation genetic testing.

Contact the clinic to arrange a fertility consultation and prepare a clear schedule for your treatment in Mumbai. Bring your GP referral, previous scan reports, test results and medication list, and ask when results will be discussed and which options they may support. Request an itemised estimate covering consultations, scans, laboratory work and follow-up. A coordinated assessment gives you clearer information and a practical next step without assuming that one scan can provide a complete answer.
