What To Think About
- 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 Reference Pelvic Ultrasound.
- Some early tests to find the cause of infertility may include tests such as semen analysis and blood tests for Reference luteinizing hormone (LH) Opens New Window, Reference progesterone Opens New Window, or Reference follicle-stimulating hormone (FSH) Opens New Window. If these tests can't find the cause of infertility, a hysterosalpingogram may be done. For more information, see the topic Reference Infertility Testing.
- A hysterosalpingogram 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.
- Reference Hysteroscopy Opens New Window 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 Reference Hysteroscopy or Reference Laparoscopy.
- 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 dyes.
- Be sure your doctor knows if you take metformin (such as Glucophage) for diabetes or for any other reason, such as Reference polycystic ovary syndrome (PCOS) Opens New Window, because of the possible interaction with the dye used in this test.
