Hysterosalpingogram (Uterotubogram) or HSG is a specialized X-ray of the uterus and tubes to find out if the uterine cavity is normal, and the fallopian tubes are open. It can be quite painful; and is conducted after the menstrual flow has just stopped.

Hysterosalpingogram (Uterotubogram) or HSG is a specialized X-ray of the uterus and tubes. Since the word hysterosalpingogram is quite a mouthful, most doctors refer to it as a HSG. Most infertile women who have done a HSG prefer not to refer to it at all, because it is quite a painful procedure.

Another limitation is that they will rarely provide any information as to why the tubes are blocked. Occasionally, however, this can be suspected by other signs (for example, by seeing the tubercles diagnostic of TB in the abdomen during laparoscopy).
