HealthDay News -- According to a study published in the American Journal of Obstetrics & Gynecology, probiotics have no effect on vaginal health for pregnant women.

Christian Gille, MD, from the University Children's Hospital in Tuebingen, Germany, and colleagues conducted a randomized trial in which oral Lactobacillus rhamnosus GR-1 and L. reuteri RC-14 or placebo were administered for 8 weeks. 

Participants included 320 women with less than 12 completed weeks of pregnancy. Vaginal swabs were taken before (290 women) and after (271 women) the intervention.

The researchers observed a decrease in the proportion of normal vaginal microbiota, from 82.6 to 77.8% in the treatment group and from 79.1 to 74.3% in the placebo group. After the intervention, there were no significant differences across groups (P=.297).

"Oral probiotics may be suitable for implementation in antenatal care, but as administered here, had no effect on vaginal health during mid-gestation," the authors write. "Other application routes or probiotic preparations may be more effective in supporting vaginal microbiota during pregnancy."
