Endometrial Receptivity Analysis (ERA)
Endometrial Receptivity Analysis (ERA) is a test to assess the endometrial status and determine the presence of a receptive gene profile in the patient's endometrium during the biopsy.
The human endometrium is a highly dynamic tissue that is capable of undergoing physiological changes in response to steroid hormones. Thus, it creates a receptive status that is synchronized with the arrival of an implanting blastocyst (refers to an embryo that is 5 days old after successful fertilization).
