If you have had implantation failure, we can help you

It is a state-of-the-art diagnostic method, to evaluate, from a molecular point of view, the status of the endometrial receptivity.

ERA indicates the window of implantation (WOI), increasing your chances of successful transfer. The endometrial receptivity is the status in which the endometrium is ready for embryo implantation to take place. This occurs around days 19-21 in each menstrual cycle of a fertile woman. Until now, the only study done on the endometrium was an ultrasound scan, and there was no analysis method available to help doctors in their clinical practice.

Now, during the process to treat an infertile couple, the ERA test (Endometrial Receptivity Array) leads to the evaluation, at the molecular level, of the endometrial factor. This molecular tool allows us to diagnose whether the endometrium is receptive or not by analysing the expression of a group of genes related to endometrial receptivity. For that, an endometrial biopsy must be performed at P+5 (hormone replacement therapy cycle) or at LH+7 (natural cycle), and after its shipment to our installation, the expression of 238 genes is analyzed. According to these expression values, the endometrium is classified as receptive or non-receptive by a computational predictor.
