RCT to Assess the Impact of Microbiome Status in Infertile IVF Patients at Their First IVF/ICSI Cycle
1,018 participantsStarted 2021-08
Plain-language summary
Although the endometrium has been traditionally considered free of bacteria, recent studies have documented the presence of an endometrial microbiome. The uterine microbiome can be defined as Lactobacillus-dominated (\<90% Lactobacillus spp.) or non-Lactobacillus-dominated (\<90% Lactobacillus spp. with \>10% of other bacteria). The presence of a pathogenic microbiota in endometrium was associated with significant decrease in implantation, pregnancy, ongoing pregnancy and live birth rates. Some of these pathogens microorganisms can also produce infection and inflammation that may lead to chronic endometritis.
Nowadays, the endometrial microbiome can be investigated with the EMMA test and the most known pathogens related with chronic endometritis can be detected with the ALICE test,both of them developed by Igenomix group. Our goal in this project is to investigate at what extent, if any, the analysis of the endometrial factor, at a microbiome level, in patients at their first IVF cycle improves their clinical outcome.

* Inclusion criteria
* Patients whose written IC approved by the EC has been obtained, after having been duly informed of the nature of the study and voluntarily accepted to participate after being fully aware of the potential risks, benefits and any discomfort involved.
* Patients undergoing their first IVF/ICSI cycle (first oocyte pick up, freezing all) with their own oocytes that will receive single embryo transfer of frozen blastocyst stage embryos (day 5/6) on an HRT cycle.
* At least 2 morphologically good quality embryos already vitrified in blastocyst stage (day 5/6).
