UTI and Hormones: Menstrual Cycle and Peri-Menopause with Dr. Rachel Rubin (Part 2)


April 9, 2026

In this expert interview, Dr. Rachel Rubin, a urologist and sexual medicine specialist, discusses the profound impact of hormonal fluctuations on urinary tract health across the lifespan. She explains that the vulva, urethra, and bladder are rich in hormone receptors, making them highly susceptible to changes during the menstrual cycle, pregnancy, and menopause. Dr. Rubin advocates for the use of vaginal estrogen and DHEA as the "gold standard" for restoring the vaginal microbiome and preventing recurrent UTIs, particularly in peri- and post-menopausal patients. She also addresses the limitations of current hormone testing and the supplement industry, emphasizing the need for evidence-based care. Additionally, the discussion covers how birth control pills can alter tissue health and explores non-infectious causes of post-coital irritation, such as vestibular chafing.

Key Take Aways

Hormone Receptors in Urinary Tissue


The vulva, urethra, and bladder contain dense receptors that require hormonal balance for health.

Vaginal Estrogen as Gold Standard


Topical hormones are the most effective way to restore lactobacilli and maintain acidic pH.

Limitations of Hormone Testing


Saliva and snapshot blood tests often fail to capture the full complexity of hormonal flux.

Contraceptive Impact on Microbiome


Oral contraceptives can lower circulating testosterone and estrogen, potentially altering the vaginal microbiome.

Post-Coital Vestibular Chafing


Immediate pain after sex is often due to mechanical irritation of hormone-sensitive vestibular tissue.

Menopause Guidelines and Advocacy


Current urology guidelines support vaginal hormone use for UTI prevention, even during perimenopause.
