title: Reproductive wish represents an important factor influencing therapeutic strategy in inflammatory bowel diseases.
abstract: OBJECTIVE
  Inflammatory bowel disease (IBD) affects patients in reproductive age but little is known about the peri-conceptional use of medication for IBD. The aim of this study was to assess the type of medication used by IBD patients with the desire to reproduce and changes in medication in the peri-conceptional period.
  
  
  METHODS
  IBD patients with active conception plans and pregnant patients were prospectively recruited from the outpatient clinic of a single academic medical center. IBD-related medication and changes in this medication for reasons of a desire to conceive or pregnancy were analyzed.
  
  
  RESULTS
  In total, 61 patients (51 females; 40 with Crohn's disease, 21 with ulcerative colitis) were included. Thirteen patients (21%) used no medication, 44 (72%) used monotherapy and four (7%) used combination treatment. Of patients on monotherapy, 11 (19%) used 5-aminosalicylates, five (9%) used steroids, 11 (19%) used thiopurines, five (9%) used methotrexate and 11 (19%) used anti-tumor necrosis factor agents. Thirty-seven patients (61%) consulted a physician prior to conception. About one-third of these patients required a change in their medication due to their conception plans.
  
  
  CONCLUSIONS
  In a referral center, the majority of IBD patients with conception plans require medication for which limited information on the safety of peri-conceptional use is available. In addition, the desire to reproduce leads to medication changes in about one-third of these patients.
