Yarlap
Yarlap® is an FDA-cleared home electrical stimulation device designed to help women with stress, urge, and mixed urinary incontinence. It uses gentle electrical stimulation to retrain the pelvic floor muscles and the nerves involved in bladder control, helping reduce urgency, leakage, and improve bladder control over time.

Summary
Yarlap® is an FDA-cleared home pelvic floor electrical stimulation device that uses gentle neuromuscular electrical stimulation (NMES) delivered through a vaginal probe. It is designed to retrain the pelvic floor muscles and the nerves involved in bladder control. Current clinical guidelines consider intravaginal electrical stimulation a treatment option for women with overactive bladder (OAB)—particularly when bladder training and pelvic floor muscle training alone have not provided adequate symptom relief. It may help reduce urinary urgency, frequency, and urge urinary leakage by improving neuromuscular control of the bladder.
Important: Do not use if you have a pacemaker or other implanted electrical device, or if you are pregnant or planning to become pregnant. Consult your healthcare provider before use if you have questions about whether this device is right for you.

Quick Start Plan
- Use the device 5 days per week for 20-minute sessions (or follow the manufacturer's recommended program).
- Begin at a comfortable stimulation level and gradually increase the intensity as tolerated.
- Complete the full training program consistently, as improvements often take 6–12 weeks.
- Continue healthy bladder habits, including bladder training, limiting bladder irritants if they trigger symptoms, and maintaining good hydration.
- Track your urgency, frequency, and leakage in the PelviZen app to monitor your progress over time.
What the Research Shows
Yarlap® is an FDA-cleared home pelvic floor electrical stimulation device that delivers neuromuscular electrical stimulation (NMES) through a vaginal probe. It is cleared for women with stress, urge, and mixed urinary incontinence and is intended to rehabilitate weak pelvic floor muscles through electrical stimulation and neuromuscular re-education.
Unlike many prescription treatments, Yarlap received FDA clearance through the 510(k) process, demonstrating that it is substantially equivalent to previously cleared pelvic floor electrical stimulation devices with the same intended use. The clearance included evaluation of the device's electrical safety, performance testing, biocompatibility, and a usability study showing that women could safely and correctly use the device at home without direct medical supervision.
What Current Research Suggests
Research on intravaginal electrical stimulation has shown that it may:
- Reduce urinary urgency and urge urinary leakage
- Decrease daytime urinary frequency
- Improve bladder control in some women with overactive bladder
- Improve quality of life when used consistently over several weeks
Major professional organizations, including the American Urological Association and European Association of Urology, consider intravaginal electrical stimulation a treatment option for women with overactive bladder who have not achieved adequate improvement with first-line conservative therapies such as bladder training and pelvic floor muscle training. It is generally considered a second-line conservative therapy rather than a first-line treatment.
Good to Know
- FDA-cleared for stress, urge, and mixed urinary incontinence.
- Uses neuromuscular electrical stimulation (NMES) to activate the pelvic floor muscles and the nerves involved in bladder control.
- Most women require 6–12 weeks of consistent use before meaningful improvements are seen.
- For women with overactive bladder, it is typically used alongside bladder training and pelvic floor muscle exercises, not as a replacement.
- Do not use if you have a pacemaker or another implanted electrical medical device, or if you are pregnant or planning to become pregnant.
PelviZen Perspective
Although Yarlap is FDA-cleared for stress, urge, and mixed urinary incontinence, the current body of evidence is strongest for using intravaginal electrical stimulation as an option for overactive bladder symptoms, particularly when first-line conservative treatments alone have not provided adequate improvement. For stress urinary incontinence, pelvic floor muscle training remains the recommended first-line conservative treatment, with electrical stimulation generally reserved for selected patients who have difficulty performing an effective pelvic floor contraction or who may benefit from additional neuromuscular training. This approach is consistent with current guideline recommendations and the available clinical evidence.
PelviZen Recommendations for Overactive Bladder (OAB)
PelviZen Recommendations for Overactive Bladder (OAB)
Current research suggests that intravaginal electrical stimulation (IVES) may help reduce urinary urgency, frequency, and urge urinary incontinence by modulating the nerves involved in bladder control. While there is no universally accepted stimulation protocol, several treatment parameters have been used consistently across clinical studies.
Treatment Parameters Used in Clinical Studies
- Frequency: 10–12.5 Hz (most commonly 10 Hz)
- Low-frequency stimulation is thought to activate the pudendal nerve and inhibit involuntary bladder contractions.
- Some studies have used 20 Hz for women with urgency urinary incontinence (UUI) or mixed urinary incontinence (MUI).
- Pulse Width: 100–300 μs
- Most studies use 100 μs, although some protocols use longer pulse widths.
- Intensity: Highest comfortable level
- Stimulation should produce a noticeable pelvic floor contraction without causing pain.
- Waveform: Symmetric or asymmetric biphasic pulses
- Duty Cycle: 5 seconds on / 5–10 seconds off
Typical Treatment Schedule
- Session length: 15–30 minutes
- Frequency: Daily for home devices or 2–3 sessions per week in supervised clinical programs
- Treatment duration: 8–12 weeks
Using Yarlap®
Yarlap does not allow users to manually adjust stimulation frequency, pulse width, or waveform. Instead, users should:
- Select the manufacturer's recommended treatment program.
- Increase the stimulation intensity to the highest comfortable level.
- Complete regular treatment sessions as directed by the manufacturer.
- Continue treatment for at least 8–12 weeks, as improvements typically occur gradually.
- Combine therapy with bladder training and other behavioral strategies, which remain first-line treatments for overactive bladder.

Because Yarlap uses proprietary stimulation programs, its exact settings may differ from those reported in the literature.
