In this study we reviewed the current literature on the epidemiology and clinical features of obsessive-compulsive disorder (OCD) during pregnancy and postpartum period. The available reports on this topic have significant limitations and heterogenous methods. However, the prevalence and incidence rates of OCD reported during these two reproductive periods are higher than the rates estimated in the general population. The most common obsessions in pregnancy and puerperium were contamination and aggressive obsessions. Aggressive obsessions are observed more frequently in postpartum women compared to non-postpartum women. Pregnancy and postpartum periods appear to be risk periods for new-onset OCD. For this reason, pregnant and postpartum women should be screened with respect to OCD.
