Hi Doctor ,i am 36 yr old, I would like to ask you about the infertility.I got married 6 years ago,I got conceived 5 years back and got missed aborted.and there was block in the tube(Laproscopy is done for removing the blcok, still doctor told there is small crist on left tube).Till now we were trying but no improvement. My husband has 120 mill sperm count but occasionall progressive motility in his test,One time IUI is done before 3 years, PLease suggest us whether we can go for IUI again or IVF considering my age?
