ERA is recommended for patients who have experienced two or more two to three implantation failures, despite good quality frozen embryos. This is largely due to an inhospitable uterine environment, evidenced in about a quarter of such implantation failures. Those seeking to understand their personalized window of implantation better may also opt for such testing. In some cases, it may…

A 'mock' programmed cycle is staged with approximately two weeks of natural oestrogen to conduct an ERA test. An additional 5 full days of natural progesterone is added, following which an endometrial biopsy is performed. This is done at the LH+7 stage of the woman's natural cycle or P+5 (start of progesterone + 5 days) in a woman's hormone replacement…

To ascertain uterine receptivity for the embryo to be implanted, an advanced, personalized, and genetic diagnosis is now undertaken known as Endometrial Receptivity Analysis. This is to understand the environment in the uterus and of the endometrium and ascertain if it is ready for embryo implantation from a molecular point of view. There are various proteins in the endometrium, produced…

Endometrial Receptivity Analysis is a genetic test that takes a small sample of a woman’s endometrial lining to determine which day would be the best day to transfer the embryo during an IVF cycle.
