ERA Test

An ERA is a personalized genetic test for determining the receptive properties of the endometrium, the degree of readiness of the uterine mucosa for embryo acceptance, and implantation in a specific period. The ERA test helps every woman individually determine the best time to implant an embryo.
To conduct an ERA test, an endometrial biopsy is required in a natural or hormone-replacing menstrual cycle at a stage corresponding to the phase of the most susceptible endometrium. This is the 21st day of the natural menstrual cycle.
Its always preferred that embryos are transferred on the 5th day after the egg collection which is the blastocyst stage. During this time the endometrium grows itself via progesterone production.
