Brief Summary:
This study is intended to utilize a novel, class I (ie. lowest risk, clinical studies not required) medical device to determine whether penile length can be increased in men prior to undergoing a penile prosthesis implantation procedure.

Condition or disease Intervention/treatment Phase
Erectile Dysfunction Device: RestoreX Other: Control Not Applicable

Detailed Description:

Men with erectile dysfunction, unresponsive to conservative therapies, are recommended to undergo placement of an inflatable penile prosthesis (IPP); however, it is a common complaint post-operatively that their penis length is shorter than what it was previously.

Several attempts have been made by investigators to optimize penile length prior to placement of the penile prosthesis. Compared to other options, penile traction therapy (PTT) offers several potential advantages in that it is minimally-invasive, does not increase the morbidity of surgery, and has not been shown to result in any long-term side effects.

A new penile traction device (RestoreX® ) was created and funded through Mayo Ventures. Given the clinical issue of dissatisfaction with penile length post IPP, the potential role for PTT, and limited amount of data available, we sought to perform a clinical trial evaluating the effect of PTT on increasing the total length of prosthesis which can be inserted. We additionally sought to determine if PTT resulted in improved post-operative satisfaction on total penile length achieved.

To accomplish the study, a population of men from Mayo Clinic planning to undergo placement of an IPP will be enrolled and given the option to either join the control (no treatment) group or PTT group for 3 months prior to their procedure. Outcomes will be assessed prior to surgery and 3, 6, and 12 months post-procedure. Results are to be used with the intent to publish in a scientific journal.

Primary Outcome Measures :
  1. Length Assessment of Penile Prosthesis Implanted [ Time Frame: From baseline to 3 months ]
    The primary objective is to assess the length of the penile prosthesis inserted into subjects following completion of RestoreX® traction therapy compared to the control group (no treatment)

Secondary Outcome Measures :
  1. Participant Compliance [ Time Frame: From baseline to 3 months ]
    Compare Participant compliance with traction device

  2. Participant Satisfaction with Traction [ Time Frame: From baseline to 3 months ]
    Compare patient reported satisfaction with use of traction device

  3. Adverse Events with use of Traction [ Time Frame: From baseline to 3 months ]
    Evaluate any adverse events with use of RestoreX® for penile lengthening.

  4. Operative Complications [ Time Frame: 3, 6, 12 months post-operative ]
    Compare intra- and/or post-operative complication rates.

  5. Stretched Penile Length [ Time Frame: From baseline to 12 months ]
    Compare pre- and post-operative stretched penile lengths

  6. Participant Satisfaction Penile Length [ Time Frame: Baseline to 12 months post-operative ]
    Compare participant satisfaction scores including satisfaction with overall penile length
