Big effect
A live Lactobacillus crispatus product significantly reduced bacterial vaginosis recurrence — but efficacy was incomplete and hinged on baseline microbiota.
This is one of the first rigorous trials to show that a specific Lactobacillus strain can prevent BV recurrence, but the incomplete effect and novelty mean it's not yet a proven solution for everyone.
The study tested a probiotic containing Lactobacillus crispatus (LACTIN-V) after standard antibiotic treatment for bacterial vaginosis. It significantly reduced the chance of recurrence by helping women maintain a healthy vaginal microbiome. However, the benefit was not universal — it worked best in women with certain baseline vaginal bacteria and other factors, and the effect was not complete.
Where this fits in the evidence
This is among the first studies we've indexed on Lactobacillus crispatus for Reduced Recurrence of Bacterial Vaginosis — treat it as an early signal until more research accumulates.
