Testosterone therapy for improving pelvic floor muscle function in older women

A Pilot Study to Evaluate the Anabolic Effect of Testosterone on Muscles of the Pelvic Floor in Older Women With Stress Urinary Incontinence

Phase 2 Interventional Brigham and Women's Hospital · NCT06111209

This study is testing if testosterone therapy can help improve pelvic floor muscle function and reduce urinary problems in postmenopausal women aged 60 and older who experience stress urinary incontinence.

What this trial studies

This clinical trial investigates the effects of testosterone therapy on pelvic floor muscles in postmenopausal women aged 60 and older who suffer from stress urinary incontinence. It is a 12-week, double-blind, randomized, placebo-controlled trial designed to assess whether testosterone supplementation can enhance the volume of pelvic floor muscles and improve urinary function. The study will utilize magnetic resonance imaging (MRI) to measure muscle volume and urodynamic testing to evaluate bladder and urethral function. Additionally, participants will report their urinary symptoms and quality of life through validated questionnaires.

Who should consider this trial

Good fit: Ideal candidates are postmenopausal women aged 60 years and older with medically documented pure stress urinary incontinence.

Not a fit: Patients with urge or mixed urinary incontinence, recent pelvic floor muscle training, or significant pelvic organ prolapse may not benefit from this study.

Why it matters

Potential benefit: If successful, this therapy could significantly improve urinary function and quality of life for women suffering from stress urinary incontinence.

How similar studies have performed: While testosterone therapy for pelvic floor disorders is a relatively novel approach, previous studies have shown promising results in related areas, suggesting potential for success.
