A Hysterosalpingogram is a type of an X-ray in which the uterus and fallopian tubes are examined. It is typically used as part of an infertility diagnostic. The Hysterosalpingogram allows the physician to visualize the inside of the uterus and the tubes and look for any abnormalities such as dilation or blockage. An HSG is an outpatient procedure that takes less than one half-hour to perform. It is usually done after menses have ended, but before ovulation, to prevent interference with an early pregnancy.
The purpose of the Hysterosalpingogram is diagnostic, and is not intended to fix anything. However, some couples have found they were able to conceive after a Hysterosalpingogram. This is because the procedure uses a liquid containing iodine to assist with the x-ray. In certain cases, forcing this dye through the tube will make any material blocking it dislodge. If this blockage of the tube was the only factor in a couple’s infertility, it is likely that they would be able to conceive soon after.
