An observational study in Erectile Dysfunction, sponsored by Boston Scientific Corporation. Enrolling by invitation at 25 sites in 3 countries. Open to male participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-09-14.
Sponsored by Boston Scientific Corporation · Observational
The objective of the It MATTERS registry is to collect Real-World Data (RWD) to monitor the safe and effective use of commercially available Boston Scientific Corporation (BSC) penile prostheses
IT MATTERS is a prospective, multicenter, observational registry that is part of planned, active post market clinical follow-up (PMCF) activity associated with each device.
The study will include adult males who undergo penile prothesis implantation with a market approved BSC device to treat erectile dysfunction.
Adult males who meet the indications for surgical correction of erectile dysfunction will be enrolled.
Exclusion Criteria:
Men for whom BSC Penile Prothesis is recommended.
Device: Tactra Malleable · Device: Spectra™ Concealable Penile Prothesis · Device: AMS Ambicor™ Inflatable Penile Prosthesis · Device: AMS 700™ Inflatable Penile Prosthesis w/Momentary Squeeze (MS) Pump · Device: AMS 700™ Inflatable Penile Prosthesis w/Tenacio™ Pump
The Tactra™ Penile Prosthesis is a sterile, single-use implant that is intended for use in the treatment of chronic, organic, erectile dysfunction (impotence) in adult males who are suitable candidates for implantation procedure.
The Spectra Penile Prothesis is a sterile, non-pyrogenic, single-use implant that is intended for use in the treatment of chronic, organic, erectile dysfunction (impotence) in men who are determined to be suitable candidates for implantation surgery.
The AMS Ambicor inflatable penile prothesis intended for use in the treatment of chronic, organic, male erectile dysfunction (impotence) in adult men who are determined to be suitable candidates for implantation surgery.
The AMS 700 Inflatable Penile Prosthesis is intended for use in the treatment of chronic, organic, male erectile dysfunction (impotence).
The AMS 700 Inflatable Penile Prosthesis is intended for use in the treatment of chronic, organic, male erectile dysfunction (impotence).
Change from baseline to six months in the Erectile Function domain ofthe International Index of Erectile Function (IIEF-EF) questionnaire for Tactra
The International Index of Erectile Function (IIEF) is a validated, widely used, multidimensional self-report instrument for the evaluation of erectile function. It consists of 15 items that assess sexual function in five domains: erectile function (Q1, 2, 3, 4, 5,15), orgasmic function (Q9,10), sexual desire (Q11,12), intercourse satisfaction (Q 6,7,8) and overall satisfaction (Q 13,14). A score of 0-5 is awarded to each of the 15 questions. The IIEF-15 total score is the sum of the ordinal responses to the 5 domains. The erectile function (EF) domain is the most sensitive domain of the IIEF. IIEF-EF score ranges from 1 to 30 and is derived by scoring 0 (poorest function) to 5 (best function) on each of six questions function (Q1, 2, 3, 4, 5, 15). There are five categories of erectile function based on EF domain score: severe (1-10), moderate (11-16), mild to moderate (17-21), mild (22-25) and no ED (26-30).
Time frame: Baseline to 6 months
Change in depressive symptoms and overall sexual function at Post-Surgery, 6 months, and 12 months post device implantation compared to baseline, as measured by the PHQ-9 Depression Questionnaire and the IIEF: Total Score.
The Patient Health Questionnaire (PHQ) is a diagnostic tool for mental health disorders used by health care professionals. The PHQ contains: mood anxiety, alcohol, eating, and somatoform modules. The PHQ-9, is a validated tool specific to depression, scoring each of the 9 DSM-IV criteria. Scored from 0-27, the PHQ-9 is separated into five different diagnoses: minimal depression (0-4), mild depression (5-9), moderate depression (10-14), moderately severe depression (15-19), and severe depression (20-27).
Time frame: Post-Surgery, 6 months, and 12 months
Change in quality of life at 6 months, and 12 months post device implantation compared to baseline as measured by the WPAI:GH Questionnaire.
The WPAI:GH (Work Productivity and Activity Impairment Questionnaire: General Health) is a validated tool that asks a series of questions about the effect of subject health problems, both physical and emotional, on their ability to work and perform regular activities. The WPAI:GH outcomes are expressed as impairment percentages, with higher numbers indicating greater impairment and less productivity, i.e., worse outcomes, as following 6 questions: 1 = currently employed, 2 = hours missed due to health problems, 3 = hours missed other reasons, 4 = hours actually worked, 5 = degree health affected productivity while working, 6 = degree health affected regular activities. Scores are then multiplied by 100 to be expressed in percentages.
Time frame: 6 months, and 12 months
Change in erectile function at post-surgery, and 12 months post device implantation compared to baseline, as measured by the International Index of Erectile Function Domain (IIEF).

A score of 0-5 is awarded to each of the 15 questions. The IIEF-15 total score is the sum of the ordinal responses to the 5 domains.

IIEF-EF score ranges from 1 to 30 and is derived by scoring 0 (poorest function) to 5 (best function) on each of six questions function (Q1, 2, 3, 4, 5, 15). There are five categories of erectile function based on EF domain score: severe (1-10), moderate (11-16), mild to moderate (17-21), mild (22-25) and no ED (26-30).
Time frame: Post-Surgery, and 12 months
Device satisfaction at post-surgery, 6 months, and 12 months a measured by the Likert scale.
The Likert scale has the options of Very Satisfied, Dissatisfied, Neither Satisfied nor Dissatisfied, Satisfied and Very Satisfied. Responses will be evaluated categorically.
Time frame: Post-surgery, 6 months, and 12 months
Assess for outcomes and adverse events on AMS Tools at Post Procedure.
AMS tools will be assess by a physician survey as part of the post-procedure case report form.
Time frame: Collected only at Post-Procedure
