Talk to Gynecologist on Ivf

I am looking answer from doctors as well publicly reviewed. As I am worried and totally disappointed. I Have been trying to conceive for two years. My follicles are always grown but unfortunately conception is not occurring. I visited Dr. Sitwat Azeem and treated around 4 to 6 cycles then Dr. Salma Naqvi who did a laparoscopy to remove functional cyst then Dr Robina tahir. Dr Robina is the best doctor among all of them but I am still unsuccessful. She did DnC to remove polyp. Now I am hopeless.. Can anyone guide me should I do Ivf? Where it is Least costly with best results? Who is the best doctor in Australian Concept?
