Hi there, I have understood your concern. HSG - hysterosalpingography, is a test to know about the patency of fallopian tubes and outline of the uterine cavity. As per your reports, there is some filling defect in the uterine cavity. It can be due to adhesions or bands in the uterine cavity. It can be due to infection or some surgical procedures like currette. Also, both the fallopian tubes seem to be blocked and do not have patent lumen. I will suggest you to get laparoscopy and hysteroscopy done. If you are planning for pregnancy, this procedure will be of help. Thanks. Dr. Purushottam Neurgaonkar.
