A hysterosalpingogram or HSG tests the health of fallopian tubes (tubal patency) and uterus. The HSG fertility test uses X-rays to look inside the uterus and fallopian tubes, as well as the surrounding area when women are having a hard time becoming pregnant. Fertility specialist, Dr. Beshay, will use a hysterosalpingogram to check for:
- A blocked fallopian tube
- Problems in the uterus, such as an abnormal shape or structure, an injury, polyps, fibroids, adhesions, or a foreign object in the uterus
- Whether tubal ligation reversal surgery was successful
What to Expect in Your HSG Fertility Test
The hysterosalpingogram study, generally, only takes about five minutes to perform in our Allen, TX, fertility clinic. A dye (contrast material) flows through a thin tube into the uterus, then into the adjacent fallopian tubes. Pictures are taken using fluoroscopy as the dye spreads.
The images can show problems such as an injury or abnormal structure of the uterus or fallopian tubes, or a blockage that would prevent an egg moving through a fallopian tube to the uterus. A blockage also could prevent sperm from moving into a fallopian tube to fertilize an egg. An HSG fertility test can also spot problems that prevent a fertilized egg from attaching (implanting) to the uterine wall.
This test should be done a few days after your menstrual period to be sure that you’re not pregnant at the time. It should also be done before the subsequent month’s ovulation period (unless contraception is involved) to avoid being exposed to radiation during an early pregnancy.
