Crohn's disease reduces fertility by inducing inflammation both directly and in the fallopian tubes and ovaries and indirectly through surgical interventions and tubal adhesions associated with disease treatment. Anti-mullerian hormone (AMH) is a reliable indicator of ovarian reserve in women. The aim of this study was to compare serum AMH levels in women with Crohn's disease and healthy controls. In this study, the investigators aimed to investigate AMH and ovarian capacity in the study group with crohn's disease and in the control group without disease.
