ERA: Endometrial Receptivity Analysis

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.

The timing of embryo transfermust coordinate with your body´s menstrual cycle, neither too early nor too late, but at just the right time. For most women, the best time to transfer an embryo is the same, butfor some women, it can be different.

What is the endometrium?

The interior of the uterus is lined with a tissue called endometrium, which is prepared each month for the arrival of an embryo and it’s the nest where the embryo implants and resides during gestation.

What is the endometrium?

  • EMMA will determine whether the uterine microbial environment is or is not optimal for embryo implantation.
  • EMMA determines the abundance of healthy bacteria (Lactobacillus) in your endometrium.
  • This test also reports the presence and quantity of the most common harmful bacteria of the reproductive tract. This includes the ALICE part of the test, indicating the possible presence of bacterial pathogens that can cause chronic endometritis or other infections.
  • Microbiology counselling is available for doctors.
