• Many women undergoing IVF are unable to get pregnant, even after transferring good quality embryos.
  • Although a good quality embryo is an important starting point, it is also important to transfer the embryo into a uterus that is ready to receive the embryo.

What is the endometrium?

  • The endometrium is a tissue lining the interior of the uterus where the embryo implants and resides during pregnancy. 
  • Each month, the endometrium prepares for the arrival of an embryo. When this does not occur, menstruation begins.

Why does the endometrium matter?

  • Recent studies led by Igenomix indicate that the endometrium is a key factor for reproductive success.

What is Endometrial receptivity?

  • The endometrium is receptive when it is ready for embryo implantation to occur.
  • Embryo implantation is the adhesion of the embryo to the endometrium.
  • The endometrium is as important as the embryo for a successful IVF treatment.

What is the window of implantation?

  • The window of implantation is the period of time in which your endometrium is receptive.
  • Each woman has a unique window. For some women the window is shorter and/or displaced.
  • By knowing your personal window of implantation, you can optimize your chances of pregnancy through a personalized embryo transfer.

3 in every 10 women have a displaced window of implantation**.

How ERA® test can help you to get pregnant?

  • The ERA® test results will indicate the exact day your transfer has to be performed according to your endometrial receptivity. 
  • Our recent study confirms that a personalized embryo transfer is superior to the conventional frozen embryo transfer: 71% of women gave birth after 1 year.*
