The implantation window corresponds to the ideal moment for the implantation of the embryo, since the endometrium presents the optimal characteristics for this. Normally, the implantation window is between days 19 and 21 of the woman's menstrual cycle, which is when the endometrium is highly receptive.
For this reason, the possibilities of achieving a pregnancy will decrease if the embryo transfer is not performed at the time of the implantation window.
