The Full Form of HSG is Hysterosalpingography.

A hysterosalpingography is a type of X-ray that looks at a woman’s uterus (womb) and fallopian tubes (structures that transport eggs from the ovaries to the uterus). This type of X-ray uses a contrast material so that the uterus and fallopian tubes show up clearly on the X-ray images. The type of X-ray used is called a fluoroscopy, which creates a video image rather than a still picture.

The radiologist can watch the dye as it moves through your reproductive system. They will then be able to see if you have a blockage in your fallopian tubes or other structural abnormalities in your uterus. Hysterosalpingography may be also referred to as uterosalpingography.
