Personalized Embryo Transfer is test that identifies patient's personalized unique timing of Implantation estimating the day on which embryo transfer will be successful. The endometrial receptivity array identifies repeated implantation failure of endometrial origin and guides personalized embryo transfer as a treatment.

It is used to reveal the clinical value of the endometrial receptivity array (ERA) in patients and for guiding their personalized embryo transfer (pET) as a novel restorative strategy. The ERA test (Endometrial Receptivity Analysis) can save on time, expensive tests and diagnoses, playing a crucial role in embryo transfer and making sure the embryo is implanted in the personalized window of time in the patient.
