Recent studies have shown that the inside of the uterus is not completely free of microbes and has a unique structure called microbiome. Useful microbes can be found there as well as microbes that can cause inflammation in the uterus, causing pregnancy to occur and in vitro fertilization to fail. Here, Emma and Alice tests are used to help us understand the diversity of germs in the uterus and to regulate the treatment accordingly and make the uterus suitable for the placement of the baby. With the Emma test we can determine the density of beneficial bacteria called Lactobacillus. If there is an abnormality, it is tried to increase the chance of pregnancy by arranging the necessary support treatment before embryo transfer. In the same way, it is possible to detect harmful bacteria in the uterus with the Alice test, and thus the embryo transfer can be performed in a healthier environment by pre-transfer treatment. These tests are performed with the biopsy sample taken from the uterus as in the ERA test. In fact, Emma and Alice test together with the same piece of ERA test by performing both the gene and germ structure of the uterus by examining the whole map can be extracted and tried to achieve the most successful results. Test in which all three tests are performed is called ENDOMETRIO.
