Top claims

▪Among five Lactobacillus strains analyzed, Lactobacillus gasseri demonstrated the strongest adhesion to endometrial cells and the highest antioxidant and anti-inflammatory properties.
▪A one-year follow-up of 93 study participants who underwent embryo transfers showed that women who achieved clinical pregnancy had a higher endometrial abundance of Lactobacillus than those who did not.
▪The researchers noted that the study is early-stage and observational in humans, meaning it cannot prove that uterine microbiome changes cause endometrial aging or poor pregnancy outcomes.
