Episode 255: Your UTIs Might Not Be UTIs — What Your Bladder, Your Vestibule, and Your Hormones Have in Common
If you've ever had urinary symptoms that antibiotics didn't fix — and your cultures kept coming back negative — this episode is for you.
A new 2026 study in the Journal of Sexual Medicine followed 253 women with recurrent UTIs and persistent urogenital symptoms despite negative urine cultures. What researchers found reframes everything: 85% of these women had hormonally mediated vestibulodynia, 75% had pelvic floor hypertonicity, and only 15% had a classic urologic cause for their symptoms.
This isn't a bladder problem. It's a hormone problem — and the vulvar vestibule, urethra, and bladder are one integrated, estrogen- and androgen-responsive system. Whether it presents as genitourinary syndrome of menopause (GSM) in a postmenopausal woman or hormonally mediated vestibulodynia in a younger one, the tissue-level pathophysiology is the same.
In this episode, Dr. Carolyn Moyers breaks down:
• Why persistent urinary symptoms after negative cultures have a hormonal explanation
• The shared embryologic origin of the vestibule, urethra, and bladder trigone — and why it matters
• How androgen deficiency drives vestibular inflammation, pelvic floor guarding, and bladder dysfunction in a self-perpetuating cycle
• Why this affects premenopausal women too — 98.9% of premenopausal patients in the study had below-range free testosterone
• What the Rubin et al. 2025 data adds: vaginal prasterone (DHEA) was associated with meaningfully lower UTI rates in women with vulvovaginal atrophy — treating the hormone environment changed the urological outcome
• What integrated treatment looks like — vaginal estrogen for GSM, compounded estradiol/testosterone gel for vestibulodynia, pelvic floor PT for hypertonic muscles
• The honest limits of this research: selection bias, non-uniform hormonal evaluation, absence of long-term outcome data — and what prospective studies still need to answer
