This test examines the uterine cavity, documenting that a woman’s reproductive organs are normal in size and shape and can provide healthcare providers with insight into some fertility issues. A sonohysterogram (SHG) is one procedure that can determine if the inside of a woman’s uterus is normally shaped.

Why It Is Done

A sonohysterogram is a non-invasive way to visualize the uterine cavity in screening for uterine abnormalities. A hysterosalpingogram (HSG) also checks for uterine problems as well as determining if the fallopian tubes are open.

How It Is Done

The procedure is done at the healthcare provider’s office, usually within 10 days of a menstrual period. First, a catheter (a flexible tube) is inserted into the cervix, which is followed by an ultrasound probe being placed into the vagina. Once the uterus can be seen, a saline solution is then injected into the uterus, which helps the doctor see the outline of the uterus. Some women complain of mild to moderate cramping.
