This paper reports the fertility with Inflammatory Bowel Disease (IBD), effects of IBD on pregnancy and conversely, effects of treatment on the mother and the child. Fertility is minimally, if at all, compromised. The foetus is likely to survive in spite of active disease. There is no good evidence for an effect of pregnancy on Ulcerative Colitis and Crohn disease. Sulfasalazine and steroids should be used in IBD during pregnancy much as they are in the non pregnant azathioprine and metronidazole are contraindicated. IBD is not a reason for a young woman to avoid pregnancy and does not constitute an indication for abortion.
