About this study

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

Stress urinary incontinence is the most common female pelvic floor disorder encountered in clinical practice with significant negative impact on quality of life. The prevalence of urinary incontinence increases with aging, and weakness of the pelvic floor muscles contributes to the development of stress urinary incontinence. Given that androgen receptors are expressed throughout the pelvic floor, the anabolic effects of androgens on pelvic floor muscles may provide a therapeutic option in women with stress urinary incontinence. The investigators are conducting a randomized, double-blind, placebo-controlled proof-of-concept trial in older postmenopausal women with stress urinary incontinence to assess whether testosterone therapy can increase pelvic floor muscles and improve urinary function.

Read the detailed description

The investigators are conducting a 12-week double-blind, randomized-controlled, proof-of-concept pilot trial to determine the anabolic effect of testosterone therapy on pelvic floor muscles in postmenopausal women, 60 years and older, with stress urinary incontinence. The first aim is to compare the efficacy of testosterone supplementation versus placebo on the volume of levator ani muscles of the pelvic floor, assessed by magnetic resonance imaging (MRI). The second aim is to assess the efficacy of testosterone supplementation in improving indices of urodynamic function (i.e., bladder, urethra, and sphincter function), assessed by urodynamic testing. These urodynamic measures include Valsava leak point pressure, urethral pressure profile, cystometry and electromyography. As an exploratory aim, the efficacy of testosterone treatment relative to placebo will be assessed using self-reported urinary symptoms assessed by the Urogenital Distress Inventory (UDI) and quality of life assessed by the Incontinence Impact Questionnaire (IIQ).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in pelvic floor muscle volume

    volume of levator ani muscles of the pelvic floor, assessed by magnetic resonance imaging (MRI)

    Measured: 12 weeks

Secondary outcomes (6)
  1. Change in abdominal leak point pressure

    abdominal leak point pressure will be measured by a urodynamic function study

    Measured: 12 weeks

  2. Change in urine flow rate

    urine flow rate will be measured by urodynamic function a study

    Measured: 12 weeks

  3. Change in bladder pressure

    bladder pressure will be measured during filling, storage and voiding by urodynamic study

    Measured: 12 weeks

  4. Change in post void residual urine volume

    post void residual urine volume will be measured using bladder ultrasound

    Measured: 12 weeks

  5. Change in urinary symptoms

    self-reported urinary symptoms will be assessed by the Urogenital Distress Inventory (UDI). Total score ranges from 6-24 with higher scores indicating higher severity of symptoms

    Measured: 12 weeks

  6. Change in quality of life

    quality of life will be assessed by the Incontinence Impact Questionnaire (IIQ). Total score ranges from 0-21 with higher scores indicating worse impact on quality of life.

    Measured: 12 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Testosterone cypionate in people with Stress Urinary Incontinence and Menopause, run by Brigham and Women's Hospital at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 26 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in pelvic floor muscle volume (time frame: 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Jun 2026.
