How is a Hysterosalpingogram performed?

A HSG is a type of x-ray examination that aims to examine the presence of pathologies in the uterine cavity, and well as tubal patency. It is recommended to evaluate potential causes of primary sterility. It involves inserting a cannula until the entrance of the uterus, through which a special radio-opaque contrast material dye is inserted. The contrast material dye will fill in the cavity and the tubes. Then, a series of x-rays will be done to detect potential abnormalities or blockages in the different structures. It is a simple procedure that is typically done in the first 10 days of the cycle. During its performance, the woman may feel period-like symptoms. Hospitalization is not required, and its duration ranges between 15 and 30 minutes approximately.
