<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi i have completed four years of my married life but not yet conceived.i am 32 yrs old.last yr in Feb i was operated for tubal blockage .went for 3 cycles of iui after that but not yet conceived .is there any chance my tubes have again blocked . Can i know the same without going for HSG test or laproscopy as these are painful processes  <response>: Hi, Thanks for your query. I read your query and I understand your concerns. Following is my reply:1 Tubes can undergo blockage again due to fibrosis.2 I think considering your blocked tubal history and age, I suggest you go for IVF as soon as possible.3 If you still wish to try GUI, please get HSG test done to check tubal patency status. I hope I answered your query. Write back to me if you need more clarifications.
