The Hysterosalpingogram (HSG) test is a diagnostic test, and is the best non-surgical way to check that the Fallopian tubes are open, and that they are normal-appearing. It’s also a good screening test that can pick up polyps or fibroids inside the uterus. Sometimes we see evidence of scarring around the tubes. It’s an important fertility test to do before treatment. Some women get pregnant after the HSG test, and it’s safe to try to conceive in the month you do the test, but it’s not really a fertility treatment by itself.
