Michelle Emblenton, biochemist at inviTRA, tells us about the possible results of hysterosalpingography:
The results of the hysterosalpingography should be interpreted by your specialist, which is usually the gynecologist who has carried out the procedure. In the image, the uterine cavity can be seen as an oval or pear-shaped image which is the uterus and two thin lines coming out of it which are the fallopian tubes.
If the test is positive, it means the specialist can see the two fallopian tubes are permeable, which allows the die to move through the fallopian tubes and, therefore, there is no obstruction and everything is in working order.
If the test is negative, whether unilateral or bilateral (meaning one tube is blocked or two tube is blocked), the fallopian tubes have an obstruction which do not allow the die to pass through. In these cases, the fallopian tubes usually inflate with the die. However, it is also possible that your specialist cannot visualize the fallopian tubes due to a malformation of the tube itself.
Based on the results of this test, your specialist can then recommend the best assisted reproductive treatment for you. For example, your specialist may recommend an artificial insemination if the uterus and fallopian tubes are permeable and you are under the age of 36 years old. However, if the tubes are blocked in anyway, seminal quality is poor or you're of an advancing maternal age, your specialist will probably recommend inv vitro fertilization.
