Endometrial Studies



The endometrium is the tissue that lines the uterus internally. It is where the embryo is implanted and, when there is no embryo to implant, it is responsible for menstruating each month.

The studies performed on the endometrium serve, among other things, to be able to study the future implantation of embryos. This is because 20% of infertility may be due to a problem with the endometrium.

Among the studies that can be done we have: the study of microbiota and endometrial test. 

Microbiota Test

This test studies the endometrial bacterial flora. This means that it studies the proportion of bacteria in the endometrium to corroborate that it is correct or if there is any alteration in order to choose the most appropriate treatment.

By having the results of microbiota tests, they help gynecologists experts in assisted reproduction to coordinate treatments and new protocols to address these bacterial problems in order to achieve a successful pregnancy in a healthy bacterial flora.

EndomeTRIO Test

While the endomeTRIO test is a complete analysis of 3 studies known as ERA, EMMA and ALICE. These respectively study: the window of implantation, the endometrial microbiome to improve the reproductive factor and the cause of chronic endometritis. 

In other words, these tests make it possible to see the causes of such things as: chronic endometritis, implantation failures and/or polyabortions, also known as repeated miscarriages. 

The ERA test studies the endometrium at the molecular level through 248 genes. In this way, the exact time, the window, in which there may be a better implantation is known. In other words, it can increase the possibility of embryo implantation at the time of transfer. 

The EMMA test studies the optimal, dysbiotic and pathogenic bacteria to learn about the microorganisms existing in the uterine cavity. Thus, it is possible to have a better bacterial profile and to recommend probiotics, if needed, to improve the reproductive factor.

And finally, the ALICE test makes it possible to identify the causes of chronic endometritis. A disease that usually affects at least 10% of women in the world’s population. In this way, a personalized treatment can be sought for each patient. 

Frequently asked questions

  • In which cases is it advisable to do a microbiota test? It is recommended in case of: chronic endometriosis, implantation failure and/or in case of a history of polyabortion. 
  • What is the importance of healthy bacteria? It is important that the bacteria in the endometrial cavity are healthy because it is the environment in which the embryo develops. If the environment for fertilization is not healthy and balanced, the chances of implantation are low.
