ERA is a patented diagnostic tool developed by IVIOMICS, Spain that determines the exact time period during which an embryo needs to be transferred to the woman's uterus to achieve a successful pregnancy.
ERA can be done for patients with repeated implantation failures despite having good hormonal response, good ovarian reserve, good quality embryos and with no pathological factor hampering receptivity. It is a technique that allows to evaluate, from a molecular point of view, the status of the endometrial receptivity.
Endometrial receptivity, a status in which the endometrium is ready for embryo implantation to take place, occurs around days 19-21 in each menstrual cycle of a fertile woman. Until now, an ultrasound scan was the only study done on the endometrium and no analysis method helped the doctors in their clinical practice. ERA , a molecular tool, allows us to diagnose whether the endometrium is receptive or not by analyzing the expression of a group of genes related to endometrial receptivity.
