Endometrial receptivity array

Endometrial Receptivity Array (ERA®) may help increase the chances of successful embryo implantation in the womb lining of women trying to get pregnant.

After natural ovulation and after egg collection in IVF, there's a narrow window of opportunity (implantation window) where your womb lining (endometrium) is most likely to successfully receive an embryo. By tailoring the timing of embryo transfer to suit your body, it could optimise the chances of an embryo successfully implanting in your womb. The ERA® test involves taking a sample (biopsy) of your endometrium.

We then carry out a genetic analysis to see if the genes vital to implantation are 'switched on' and ready to receive an embryo. This test is usually only offered to people who've had repeated unsuccessful attempts at implantation.
