Endometrial receptivity analysis (ERA)

With this test we can find the best time for embryo implantation.

Endometrial receptivity analysis (ERA) is a way of finding out when the lining of the womb – known as the endometrium - is most receptive. This helps us to decide a time for your embryo transfer that’s most likely to result in success.  

Could ERA be right for me?

Embryo transfer is one of the most important stages of your IVF treatment. Sometimes, though, the embryo won’t implant, and this could be because of a problem with the endometrium.

If we think this could be an issue for you, we might suggest endometrial receptivity analysis. If you’re still unsure whether it might be an option, talk to your local clinic or contact us for support.

During the test, which is similar to a smear, we’ll take a biopsy of the womb lining then analyse the tissue to determine when your endometrium will be most receptive.

What does ERA involve?

We can carry out ERA testing either during your natural cycle, or during a cycle prompted by medication.

During the test, which is similar to a smear, we’ll take a biopsy of the womb lining then analyse the tissue to determine when your endometrium will be most receptive – we call this the window of implantation. We can then use these findings to determine the timing of your embryo transfer, which could increase the chance of successful implantation.
