Cigarette smoking is associated with an altered vaginal tract metabolomic profile

Smoking has been identified in observational studies as a risk factor for bacterial vaginosis BV , a condition defined in part by decimation of Lactobacillus spp. The anti-estrogenic effect of smoking and trace amounts of benzo[a]pyrene diol epoxide BPDE may predispose women to BV. BPDE increases bacteriophage induction in Lactobacillus spp. We compared the vaginal microbiota between smokers and non-smokers and followed microbiota changes in a smoking cessation pilot study.
