A hysterosalpingogram (HSG) is an X-ray procedure performed to evaluate your uterus and fallopian tubes. The procedure begins with a pelvic examination. Your doctor will place a catheter into your cervix.
The hysterosalpingogram allows your doctor to study the shape of your uterine cavity. Abnormalities, such as polyps, fibroid tumors, scar tissue, or congenital defects may be identified. The test also studies the inside of your fallopian tubes and whether or not they are open.
A hysterosalpingogram is usually performed during the first half of your menstrual cycle.
