概要 We detected only one equol-producing bacterial species, Bacteroides ovatus in the feces of 6 in 9 subjects analyzed, and the subjects who had more than 1% of the occupancy of intestinal bacteria demonstrated significant lower PMS scores than the subjects who had no or less than 1%. We also found the intensities of complaints in the luteal and menstruation phases when PMS symptoms were generally observed were significantly correlated with plasma concentration of 17β-estradiol. These results suggested that PMS could be affected by intestinal equol-producing bacteria and plasma concentration of 17β-estradiol, although detailed mechanisms remain to be clarified and further extensive study will be imperative.This is the first report indicating a relationship between intestinal microbiota and PMS.
