I am happy to answer your query
HSG(Hysterosalpingogram) is usually done to check the patency of Fallopian tubes. If any problem in the tubes is noticed in HSG,the best practice will be to confirm the patency of tubes by doing a diagnostic Laparoscopy
.In this procedure we can have a direct visualization of tubes and also try to unblock it if at all there is any problem.
I hope I answered your query
