Hysterosalpingogram – It is used to know whether the fallopian tubes of the patient are blocked and whether blockage is at the junction of tube of uterus (proximal) or at the distal end.

• It is a radiological procedure and done as OPD.
• Radiographic contrast dye is injected into uterine cavity through vagina and cervix.
• The cavity fills with the dye and if tubes are open, the dye fills the tube and spills into the pentoneal cavity.
• It also helps to evaluate the uterine cavity and rule out anomalies, polyps, fibroid, tumours, etc.,
• Fallopian tubes are also examined for any defects and the pelvic cavity adjacent to the tubes also assessed.

Pregnancy rates have been reported to be slightly increased in few months following HSG, probably due to flushing of tubes opening minor blockage or cleansing out some debris that was preventing conception. Use of oil based contrast provides slightly larger increased in pregnancy rates than use of water based contrast.

Complications of Hysterosalpingogram

• Allergic reaction to dye
• Abdominal cramps
