I have had Crohns disease for 12 years and have had one bowel resection last year (ileum). I take Cimzia once per month. My DH and I have been trying to conceive and cant. We have all the tests done (HSG, SIS, Semen analysis, Bloodwork) and even tried clomid and femara for a few months and nothing. My tubes are open and my uterus looks fine. So my RE is suggesting IVF. He thinks the cilia that release the egg could be scarred because of the Crohns and the surgery. We are scheduled to start some time in July so we are on a 2 month break for all fertility meds. I know that immune issues (NK cells etc) can affect fertility but my RE doesnt buy into that. Has anyone here with Crohns/Colitis had to go thru IVF? What was the experience? Was it successful?
