Jerusalem, 1 June, 2026 (TPS-IL) — A revolutionary therapeutic approach based on restoring the vaginal microbiome is showing success and offering new hope for millions of women suffering from stubborn bacterial vaginosis. Gynecologist Prof. Achinoam Lev-Sagi from Hadassah Mount Scopus Medical Center, in collaboration with Prof. Eran Elinav’s Microbiome Research Laboratory at the Weizmann Institute of Science, examined whether transplanting vaginal bacteria from healthy donors could cure women suffering from a chronic infection that does not respond to standard antibiotic treatment.
Bacterial vaginosis is a very common condition among women of childbearing age, caused by a decrease in the population of “good” bacteria in the vagina (mainly Lactobacillus) and the proliferation of harmful bacteria.
In addition to symptoms that are accompanied by severe discomfort and a profound impairment of quality of life, the condition can lead to serious health consequences, including an increased risk of contracting sexually transmitted diseases, the development of pelvic infections, and in pregnant women – pregnancy complications and premature birth. While most cases resolve with antibiotics, many women suffer from persistent infections that return again and again.
