Inflammatory Bowel Diseases (IBD) are chronic conditions affecting young people in their reproductive age. Patient misinformation can be responsible for a self-imposed infertility as well as a suboptimal observance during pregnancy. The aim of this work was to review the influence of IBD and pregnancy on one another at each gestational stage and according to current literature. IBD activity is a major influential factor. In case of a well-controlled IBD, fertility won't be affected and pregnancy will take place without increase risk of complications. With the exception of thalidomide and methotrexate, most of treatments used in IBD are compatible with pregnancy and breastfeeding. Each flare should be optimally managed. Vaginal delivery is a safe option except for patients with active anoperineal lesions. Cesarean section should be systematically discuss in patient with ileal pouch-anal anastomosis.
