Adiponectin and leptin systems in human endometrium during window of implantation

Although progesterone resistance seems to be a common state of the endometrium in some human reproductive disorders, such as endometriosis or polycystic ovary syndrome, modification in leptin endometrial expression seems to be specific to IF. These results strongly suggest that changes in Ob-R and AdipoR expression profiles [1] should be implicated in the development of uterine receptivity, and [2] may therefore be potential new targets for prediction of IF.
