article_snippet: Professor Garcia-Velasco, told MailOnline: 'The trial we are currently undertaking is trying to answer if the ERA test may help all couples from the first day all couples attend a fertility clinic, to detect endometrial defects. '
article_snippet: Understanding the "molecular clock" at play, regardless of the presence or absence of an embryo during a woman's opportune fertility window could help to identify biomarkers of endometrial receptivity useful to create an objective personalised diagnostic test for this function,' the researchers said.
article_snippet: the researchers then attempted to diagnose the woman's window of implantation, using the endometrial receptivity array test (ERA).
article_snippet: the endometrial receptivity array test (ERA) is based on the expression of 238 genes that are related to how receptive the womb lining is, established after a biopsy. '
article_snippet: The test identifies "personalised" window of implantation in women with recurrent implantation failure,' the report said.
article_snippet: It revealed her 'endometrium was pre-receptive', leading them to conclude them had been implanting the embryo too early.
article_snippet: the report notes: 'A two-day displacement of her window of implantation was diagnosed, and this determined the need to repeat the ERA test in a further HRT cycle after seven days of progesterone replacement.'
article_snippet: The researchers diagnosed each woman's window of implantation and instead of routine embryo transfer, each woman underwent implantation according to each woman cycle.
