Pregnancy & Hysterosalpingo-contrast sonography

This test is similar to the hysterosalpingogram in that it aims to study the fallopian tubes and examine any blockages therein. Obstructions to the fallopian tubes can be a cause of infertility. Where the traditional hysterosalpingogram uses an injectable dye and X-rays to examine the tubes, a hyserosalpingo-contrast sonogram uses a specially designed ultrasound probe which can be inserted into the vagina. This method has the advantage of using ultrasound rather than X-rays for imaging. Ultrasound is perfectly harmless, while X-Rays can, if performed too often, have potentially negative effects. If you have had more than a certain number of X-Rays recently, chances are your doctor will opt for the contrast sonography.
