Could a vaginal postbiotic boost IVF success?

NCT ID NCT07278024

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested whether postbiotic suppositories (containing natural bacteria byproducts) could improve the vaginal microbiome in 15 infertile women aged 30-45 who had at least two failed IVF attempts. Participants used one suppository daily for 8 weeks. Researchers measured changes in vaginal bacteria and pregnancy rates in a subsequent IVF cycle. The study is small and has no control group, so results are preliminary.

What this could lead to

If it works, this could point toward a simple way to improve pregnancy chances in women with repeated IVF failures.
