A hysterosalpingogram (HSG) is an X-ray test that looks at the inside of the uterus
and fallopian tubes and the area around them. It often is done for women who are
having a hard time becoming pregnant (infertile).
During a hysterosalpingogram, a dye (contrast material) is put through a thin tube
that is put through the vagina and into the uterus. Because the uterus and the fallopian
tubes are hooked together, the dye will flow into the fallopian tubes. Pictures
are taken using a steady beam of X-ray (fluoroscopy) as the dye passes through the
uterus and fallopian tubes. The pictures 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 and joining (fertilizing) an egg. A hysterosalpingogram
also may find problems on the inside of the uterus that prevent a fertilized egg
from attaching (implanting) to the uterine wall. See a picture of a hysterosalpingogramcamera.
Why It Is Done
A hysterosalpingogram is done to:
- Find a blocked fallopian tube. The test often is
done for a woman who is having a hard time becoming pregnant. An infection may cause
severe scarring of the fallopian tubes and block the tubes, preventing pregnancy.
Occasionally the dye used during a hysterosalpingogram will push through and open
a blocked tube.
- Find problems in the uterus, such as an abnormal
shape or structure, an injury, polyps, fibroids, adhesions, or a foreign object
in the uterus. These types of problems may cause painful menstrual periods or repeated
- See whether surgery to reverse a tubal ligation
has been successful.
In this, the tubes patency is assessed by ultrasound by pushing a fluid through
the uterus into the tubes. It is not only as accurate as HSG but has the advantage
of the women not being exposed to radiation and also of assessing the uterine cavity
and ovaries at the same time.in our experience 95% of pts opt for this saline infusion
sonographySaline infusion sonography or Sonohysterography is a specialized procedure
by which fluid, usually sterile saline, is installed into the uterine cavity, and
gynecologic sonography performed at the same time. The procedure delineates intrauterine
pathology such as polyps, Asherman's syndrome, uterine malformations or submucous

procedure, may also be used to check whether or not the Fallopian tubes are blocked.
This is involving the injection of a special dye through the cervix and into the
