A HyCoSy or HyFoSy test is a fertility scan used to assess whether the fallopian tubes are open and to evaluate the shape of the uterus. It is commonly recommended during fertility investigations, particularly when pregnancy has not occurred naturally after trying to conceive.
As part of the Fertility Assessment Hub at Umniya Fertility, HyCoSy and HyFoSy testing may be used alongside hormone testing, ultrasound evaluation, semen analysis, and fertility consultations to provide a more complete understanding of reproductive health.
HyCoSy stands for Hysterosalpingo-Contrast Sonography, while HyFoSy refers to Hysterosalpingo-Foam Sonography. Both are ultrasound-based procedures used to check whether the fallopian tubes are open.
During the procedure, a special contrast fluid or foam is passed through the cervix into the uterus while ultrasound imaging is performed. This allows the fertility specialist to observe how the fluid moves through the uterus and fallopian tubes.
The test can help identify:
HyFoSy is a newer variation that uses foam contrast and is commonly used because it can provide clearer ultrasound visualisation.
A HyCoSy or HyFoSy scan offers several advantages during fertility assessment.
Benefits may include:
The procedure is minimally invasive and is usually performed as an outpatient investigation.
The procedure is typically performed shortly after menstruation and before ovulation.
The procedure is usually performed shortly after menstruation and before ovulation.
During the test, a small amount of contrast fluid or foam is passed into the uterus while ultrasound imaging is used to assess the fallopian tubes and uterine cavity.
The procedure typically takes around 15–30 minutes. Some women experience mild cramping or discomfort during the scan, but symptoms usually settle shortly afterward.
A HyCoSy or HyFoSy test may be recommended if:
The test is commonly performed as part of a broader fertility evaluation.
HyCoSy and HyFoSy are generally safe and well-tolerated procedures.
Because the test uses ultrasound imaging, there is no radiation exposure. Some women may experience mild cramping or light spotting afterward, but this usually settles quickly.
Complications are uncommon, though there is a small risk of infection or temporary discomfort. Your fertility specialist will review your medical history before the procedure to ensure the test is suitable for you.
In some cases, pregnancy rates may improve in the months following tubal flushing procedures such as HyCoSy or HyFoSy.
This may occur because the passage of contrast fluid through the fallopian tubes can occasionally help clear minor debris or mucus plugs. However, the primary purpose of the test is diagnostic rather than therapeutic.
Most patients can begin trying to conceive again immediately after the procedure unless advised otherwise by their fertility specialist.
Because the test is often performed shortly before ovulation, some patients may continue trying to conceive during the same cycle.
A HyCoSy or HyFoSy test may provide information about:
Results are interpreted alongside hormone testing, ultrasound findings, semen analysis, and other fertility investigations where appropriate.
At Umniya, HyCoSy and HyFoSy testing forms part of the broader Fertility Assessment Hub, which brings together fertility investigations in a coordinated and personalised approach.
Before the procedure, a fertility specialist will review your medical history and explain how the test is performed. During the scan, patients are supported by an experienced clinical team focused on comfort, privacy, and clear communication.
Following the procedure, results are reviewed in the context of your broader fertility assessment and treatment plan.
Most women experience mild to moderate cramping during the procedure, similar to menstrual cramps. Discomfort is usually temporary and settles quickly afterward.
Comfortable clothing is generally recommended. You may also be asked to wear a clinic gown during the procedure.
Both tests assess the fallopian tubes, but HyCoSy uses ultrasound rather than X-ray imaging. The most appropriate test depends on your medical history and fertility assessment.
HyCoSy does not usually delay ovulation. The procedure is typically scheduled early in the menstrual cycle before ovulation occurs.
Risks are generally low but may include temporary cramping, light spotting, or rare infection. Most patients recover quickly and return to normal activities the same day.
