Can vaginal estrogen reduce UTIs?

Vaginal estrogen can indeed be effective in reducing UTIs (Urinary Tract Infections). According to Rena Malik, applying estrogen locally in the vagina—through creams, suppositories, or rings—can lower the pH level of the vagina. This creates an environment less conducive to UTIs by converting glycogen to lactobacilli, which helps prevent infections. It is particularly helpful for women in low estrogen states, such as perimenopause or menopause. This method has been shown to be both very effective and safe, with minimal risks of side effects like breast tenderness or discharge, and requires consistent use for about three months to see results 1.

Mary Claire Haver, M.D. also emphasizes that vaginal estrogen is highly beneficial for reducing recurrent UTIs in menopausal women, advocating its use over recurrent antibiotics. She notes that it can significantly cut down the number of emergency room visits for urocepsis in elderly women by maintaining the health of the urethra and vaginal tissue 2.
