Scott’s post is a good summary of the cost-benefit issues, but in my mind the colon cancer risk looms as much larger and more concerning than the risk of infertility- at least as time goes on with no surgery. It was ultimately the decisive factor for me. However I had poorly controlled UC for 20 years, not 8, and the cancer risk was greater, and I also had dysplasia. Your post is silent on the results of biopsies/dysplasia. However it doesn’t sound like your treatment is headed in the right direction despite biological drugs and that is, and should be, very concerning. Good luck with the decision.
