Hi. We are married since 3 years and trying to conceive more than year now. I had all my basic test done all normal ,husband semen analysis normal, follicular study ok dominant follicle ruptured at 23 mm. After having three months regular fertility medicines (qgold, coretia, borncal).Doctor suggested for hsg test. Its says chronic salpingitis and bilateral patent tubes. Doctor suggested me antibiotics. Please advise if I need to go for endometrial biopsy. Can this be TB Or antibiotics are enough. How would I come to know infection has gone I mean blood/urine test can validate that? Attached reports.
