In some cases, a pelvic ultrasound test may be
done instead of a hysterosalpingogram to find foreign objects in the uterus,
such as an intrauterine device (IUD). For more information, see the topic
is done mainly for women who are having a hard time becoming pregnant. Some
studies show that this test may help a woman's chance of becoming pregnant
because the dye may remove mucus plugs, straighten the fallopian tubes, and
break through thin scar tissue.
may be done instead of a hysterosalpingogram to look at the uterus. Another
test called laparoscopy may also be done instead of a hysterosalpingogram to
look at the fallopian tubes. A laparoscopy does not show whether the fallopian
tubes are open, unless dye is injected during the laparoscopy. For more
information, see the topics
Another test, a
sonohysterogram (SHG), may be more accurate than a hysterosalpingogram for
looking at uterine fibroids or polyps. SHG uses ultrasound to watch the
movement of a salt solution (saline) that is injected into the uterus. SHG does
not use X-rays or an iodine dye.
If a blocked fallopian tube is the cause of infertility, an
oil-based dye may be used during a hysterosalpingogram to remove the blockage.
Some studies show that an oil-based dye may open up a blockage better than a
water-based dye, but other studies have shown no difference between the two
Be sure your doctor knows if you take metformin (such as Glucophage)
for diabetes or for any other reason, such as
polycystic ovary syndrome (PCOS), because of the
possible interaction with the dye used in this test.
