What is HSG?
By Dr Babajide Alalade
A hysterosalpingogram (HSG) is an x-ray procedure or test which enables to healthcare practitioner to looks at the inside of the uterus and the fallopian tubes and the surrounding area near them. It is usually done as part of infertility investigation.
A dye is injected from the cervix in to the womb and passes through the tubes, to enable x-rays to be used to visualize the normal anatomy of the female reproductive organs.
The uterus and the fallopian tubes are hooked together, the dye will flow into the fallopian tubes.
Then x-ray pictures are taken as the dye passes through the uterus and fallopian tubes.
The x-ray pictures taken are able to 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.
Such blockage also could prevent sperm from moving into a fallopian tube and joining (fertilizing) an egg.
Why it is Done:
A HSG is done to:
• Check for 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.
• It could be used to localize problems in the uterus, such as an abnormal shape or structure, an injury, endometrial polyps, fibroids, adhesions, or a foreign object in the uterus. These types of problems may cause painful menstrual periods or repeated miscarriages.
• It could be used to assess whether surgery to reverse a previous tubal ligation has been successful.
