This study evaluates the feasibility and efficacy of the penile tracking sensor, a wearable device that monitors nocturnal penile tumescence (NPT), as a non-invasive, biofeedback-based intervention for men aged 18–40 diagnosed with psychogenic erectile dysfunction (ED). The objective is to determine whether real-time feedback on spontaneous nocturnal erections can improve erectile confidence and reduce psychological barriers such as performance anxiety.

A prospective observational study was conducted to assess the device's usability, impact on psychological outcomes, and erectile function in real-world home-based settings. Participants were recruited through clinical referrals and screened to confirm a diagnosis of psychogenic ED with no significant organic pathology. Eligible male participants were provided with the penile tracking sensor, developed and supplied by Adam Health, the company responsible for the device's design and production. Participants were instructed to wear the device overnight at least three times weekly for a four-week period. Pre- and post-intervention assessments included the International Index of Erectile Function (IIEF), validated psychological scales measuring erectile confidence and performance anxiety, and questionnaires evaluating device usability and adherence.

Biofeedback from the penile tracking sensor enabled participants to confirm the presence of normal nocturnal erections, thereby reinforcing physiological capability and reducing psychological barriers to sexual performance. In patient-reported outcomes, participants indicated improved ability to achieve and maintain erections, greater ease of penetration, reduced difficulty maintaining erections during intercourse, and enhanced sexual satisfaction. These findings suggest that biofeedback from the tracking device may directly enhance erectile confidence and sexual performance in men with psychogenic ED.

Using the penile tracking sensor gave participants visual proof that their bodies were functioning normally during sleep, which helped reassure them that their physical ability to get erections was not the problem.

The penile tracking sensor shows potential as an effective, home-based, non-pharmacologic intervention for psychogenic ED. While these early findings are promising, larger randomized controlled trials are required to confirm efficacy, assess long-term outcomes, and support broader clinical implementation.
