Fresh versus frozen embryo transfer: New approach to minimize the limitations of using national surveillance data for clinical research

A narrative review on endometrial receptivity in adenomyosis and/or endometriosis reveals that this parameter is difficult to assess in natural conception, as both disorders alter natural fertility. Recent data emanating from ART have allowed to study endometrial receptivity in women affected by adenomyosis and endometriosis. This has upended our views on the effects of these two disorders on embryo implantation. Today, the very existence of altered receptivity in ART is questioned.

Adenomyosis and endometriosis share in common to both result from the development of endometrial tissue outside of the endometrium. In spite of this, the two disorders were until recently considered as two different entities notably, because of their different epidemiology. Today however, new findings regarding core similarities in pathophysiology and endometrial receptivity – not altered in ART when using frozen embryo transfers – tend to reunite these two ailments as variants of one disorder.
