Inflammatory bowel diseases (IBD) affect mainly young population. Therefore, fertility and pregnancy are important clinical issues to be considered. Generally, fertility in IBD patients is not decreased either in males or females when compared to a healthy population. Moreover, drugs used for IBD treatment do not significantly affect fertility in humans. However, prolonged treatment with sulphasalazine may reduce semen quality and cause reversible infertility.

Since the disease course and a risk of pregnancy-related complications depend mainly on disease activity at the time of conception, female patients with IBD should plan their pregnancy during a remission phase. Methotrexate, mycophenolate mofetil and thalidomide are strongly contraindicated during pregnancy. Other medications used for IBD seem to be safe provided that they are administered with caution.

In 2015, European Crohn’s and Colitis Organisation (ECCO) published its Consensus on Reproduction and Pregnancy in IBD. However, management of IBD during the reproductive age and during pregnancy still remains controversial, since evidence-based data come mostly from retrospective studies.

The aim of this paper was to discuss the issue of reproduction and pregnancy in IBD patients based on current ECCO guidelines and literature.
