Our doctors at Family Beginnings perform several diagnostic services that assist with infertility assessment.

The Endometrial Receptivity Assay (ERA) assesses the “implantation window”. It’s assumed that there is an optimal time for embryos to implant. If the embryo is present in the uterus before or after this window of time, it may not implant. The diagram below shows the pre-implantation window, the implantation window, and the post implantation window. The ERA checks for over 270 molecules that are associated with optimal implantation. It makes sense that all patients are unique and will respond differently to the typical frozen embryo transfer protocol. Why should we force everyone to do the same protocol? The ERA lets us optimize this for each individual patient by doing a mock cycle, where we do an endometrial biopsy at 120 hours of progesterone.
The second diagram below shows a few sample reports. The first report shows an optimal time for implantation one day earlier than expected. For this patient, a Day 5 embryo needs to be implanted on Day 4. The middle report shows an endometrium right on target at 120 hours of progesterone, and the bottom report shows a lining shifted 12 hours.
We feel that this test provides actionable information.
