HyFoSy test is a procedure that can help diagnose infertility conditions in females and offer the right treatment. This test detects tubal blockages or any type of abnormality in the fallopian tube by using an ultrasound technique with ExEm foam gel that works as a contrast medium for the ultrasound.
Earlier, this HyFoSy (hysterosalpingo-foam sonography) test was known as HyCoSy (hysterosalpingo-contrast sonography) because of the use of Levovist as a contrast medium. In the medical field, HyFoSy treatment is considered safer and more accurate than traditional tests like laparoscopy, HSG or dye test.
About The Test
This test is commonly done before infertility treatment using ultrasound to locate any blockage in the fallopian tube. This test uses ExEm foam as a saline medium to get contrasts of the fallopian tube in the ultrasound. Before performing the test, the doctor scans the pelvic region to assess the transvaginal anatomy.
The ExEm foam gel is introduced in the fallopian tube with the help of a vaginal probe and a small sterile plastic catheter of 2mm in size. The ultrasound images produce a bright echo of the fallopian tube due to the presence of ExEm foam inside.
It makes assessing the entire fallopian tube and the spillage around it easier with clear visuals. For example, if the spilling on both sides of the fallopian tube is unclear, the tube might be blocked.
Risk Factors Associated With The Test
In general, the HyCoSy test is a safe procedure, but it can involve certain risk factors, such as:
- Bleeding: It might happen during the procedure or after the test. You can feel slight to mild pain during the test, but if the bleeding becomes uncontrollable, it may be a reason for worry. In such a case, you should inform your doctor immediately so that they can take proper action and solve this problem.
- Infection: If you have had any kind of infection in the urinary tract or vaginal area, then there is every possibility that you may develop an infection in your pelvis during HyFoSy. The doctor will also suggest you get proper treatment for such infections as it is an important step for a better result.
Preparing For The Test
Before going to the doctor, you need to ensure that you are not suffering from any vaginal infection or disease. The doctor may suggest the following tips:
- Avoid intercourse in the month of doing the HyFoSy test.
- Inform your doctor of any type of vaginal infection or disease you might suffer.
- Avoid consuming alcohol and smoking at least a week before going to the doctor for this test.
A full bladder is unnecessary for this test, as the ultrasound is done to visualize the fallopian tubes. You can consult a doctor to learn more about the procedure preparation.
What To Expect From The Test?
It is a procedure that can be done in the clinic with local anaesthesia. Generally, the procedure takes 30 to 40 minutes and might involve some slight pain during that period. Once you are done with the test, you will be taken to the recovery room and given prescribed analgesics.
In case of any problem or complications concerning the HyFoSy test, it may take more time to get a clear picture of your fallopian tube anatomy.
Possible Results Of The Test
Any blockage or abnormality in the fallopian tube means there is a possibility for infertility, and it should be addressed with proper treatment by a qualified doctor. The most common reason for the HyCoSy procedure is ectopic tubal pregnancy, where the fertilized egg re-enters into the Fallopian tube rather than the uterus after implantation. HyFoSy/HyCoSy test detects any type of blockage or abnormalities that could be the possible cause of infertility in a woman.
When To See A Doctor?
If you have had a problem with infertility for more than a year or have failed to conceive for more than two years, then it is better to go for a check-up with your doctor. The doctor will advise you with further steps to solve your fertility problem.
If you are facing any kind of difficulty in getting pregnant even after a year or two years, you should not waste your time and undergo proper treatment as soon as possible. It may also give rise to other complications like cavities in the ovary and other problems. If you have any doubts regarding HyCoSy treatment, you should consult your fertility doctor in Bengaluru before going for it.

Yes, it is safe for the doctor and the patient first-hand, but there may be certain risks.
Both these treatments are identical to each other as they use ultrasound techniques. The major difference Is that HyFoSy uses ExEm foam gel, and HyCoSy uses a saline base.
With specialists in this field, it will take 15 to 20 minutes to get results.
Do not have intercourse until after the examination on the first day of your period. The implantation of an embryo could be disrupted by this procedure. Intercourse (whether protected or unprotected) will prevent doctors from completing your cycle and a charge will be applied
There was a 40.9% conception rate in our study among infertile women after 4D-HyCoSy. Within one year after 4D-HyCoSy, the mean conception time was (8.8 + 0.3) months.
