Endometrial Receptivity Analysis ERA
& Timed Embryo Replacement

You will need to undergo a traditional cycle of IVF treatment in order that we can collect and fertilise your eggs with your partners (or donors) sperm and monitor your developing embryos in our laboratory.

If we have advised that an ERA and timed replacement is necessary, we will freeze your embryos for use at the optimum time in your cycle, conducive with the ERA test results or for a subsequent treatment. The ERA test will have to be done either in a natural cycle or medicated cycle to mimic the type of cycle to be chosen for the actual frozen embryo replacement. So in the event the transfer is to be scheduled in a natural cycle, then the biopsy will be taken 6 days after confirmed ovulation by ultrasound (or 7 days post LH surge). Alternatively, if you have been advised a transfer in a medicated HRT cycle then the biopsy will be taken on the 6^th day of progesterone administration.

A biopsy is quickly and easily taken by our consultant in our procedure room. The test will be able to advise whether your endometrium is receptive or non-receptive.

If receptive, this indicates that your window of implantation falls on the day of your cycle during which the biopsy was performed and that an embryo could be transferred to the uterus during this same period in a subsequent frozen embryo transfer cycle following the same regime
