In this study, we aimed to assess the cervicovaginal environment (pH, Nugent score, soluble immune factors and bacterial profile) in women with reproductive failure because of either repetitive abortion or infertility of unknown origin and compare it to that of healthy fertile women. The second objective was to evaluate the ability of Lactobacillus salivarius CECT5713 to modulate such parameters and to increase pregnancy rates in women with reproductive failure. The administration of L. salivarius CECT5713 (~9 log10 colony-forming units (CFU)/day) for 6 months or until a diagnosis of pregnancy to women with reproductive failure resulted in an overall successful (term) pregnancy rate of 56%.
