الوصف: Study question Is there an association between the composition of the endometrial microbiota and the reproductive outcomes in infertile patients undergoing in vitro fertilization (IVF)? Summary answer The composition of the endometrial microbiota (EM) prior to embryo transfer is associated with the different reproductive outcomes: live birth, no pregnancy or clinical miscarriage. What is known already The investigation of bacterial communities in the female reproductive tract using molecular methods has revealed the existence of a continuum microbiota that extends from the vagina to the upper genital tract. Previous evidence suggests the existence of an association between the vaginal and endometrial microbiome composition with reproductive and obstetrical outcomes. Specifically, the presence of specific pathogens together with low abundance of Lactobacilli has been associated with poor IVF outcomes. Study design, size, duration Multicentre prospective observational clinical study analysing the EM of infertile patients undergoing IVF (with maternal age ≤40) or ovum donation (≤50 years). A total of 452 infertile patients undergoing IVF/ovum donation were assessed for eligibility in 13 reproductive clinics in Europe, America, and Asia. The duration of the study was 30 months and the recruitment period extended between August 2017 and February 2019 (ct.gov 03330444). Participants/materials, setting, methods Endometrial fluid and endometrial biopsy were collected during a hormonal replacement therapy cycle after 5 days of progesterone (P) administration prior to a frozen embryo transfer cycle. Endometrial microbiota (EM) composition was analyzed using 16S rRNA gene sequencing using compositional data to transform scale-invariant values in both sample types. The EM in fluid and biopsy was associated with live birth, biochemical pregnancy, clinical miscarriage, or no pregnancy. Main results and the role of chance Of the 452 patients assessed, 44 did not meet the selection criteria and were excluded for the ...
