Hi and thanks for the query, The past history of tubal events some how reduces the chances of getting pregnant. However, if the hysterosalpingography revealed tubal patency, I believe the chances of getting pregnant are still very much there. Placentrex is a good drug, but must not be relied on entire. It improves outcome for sure. However, compliance with your infertility specialists advice, and treatment plan is fundamental. This is usually a step wise process in the management plan and ,might take some time. You thus require to be patient and compliant to the treatment. Following advice especially on having intercourse more regularly during fertile periods of fundamental importance. I still your chances are there to be pregnant, but compliance to treatment in such cases is the key issue. Thanks and best regards, Luchuo, MD.
