Biofeedback-guided pelvic floor training restores or improves erectile function, including after radical prostatectomy, at a high evidence level. Short programmes reduced to one or two demonstration sessions are not enough.

Level 5 maintained. Two randomised trials in independent settings found pelvic-floor biofeedback training superior to a bona fide comparator. Dorey 2004 and 2005: 55 men with erectile dysfunction of more than 6 months, five 30-minute sessions of pelvic-floor muscle exercises with biofeedback and lifestyle advice against lifestyle counselling alone — erectile function improved in the biofeedback arm at 3 months (p < .001) but not in the control arm (p = .102); after 6 months of home exercise, blinded assessment found 40 % achieving a normal erection, 35.5 % improved and 24.5 % unchanged. Prota 2012: 52 men after radical prostatectomy, weekly 30-minute anal-electrode EMG biofeedback for 12 weeks with home exercise against verbal instruction in pelvic-floor contraction — 47 % versus 12.5 % recovered potency at 12 months (p = .032). Perez 2018 (n = 52, ten preoperative sessions against none) reports much lower rates of postoperative erectile dysfunction and incontinence, while de Lira 2019 (n = 31, only two supervised preoperative sessions) found no difference at 3 months. Akdagcik 2026, a systematic review of 12 post-prostatectomy randomised trials, is mixed: four reported an erectile-function benefit and seven no between-group difference.
In short
Clinical reading
AAPB Level 5, maintained by NeuroLogic: two independent RCTs (Dorey 2004-2005 in non-iatrogenic dysfunction, with blinded assessment; Prota 2012 after prostatectomy, 47 % vs 12.5 % potency recovery at 12 months) showed superiority over bona fide treatments. The 2026 post-prostatectomy systematic review (Akdagcik, 12 RCTs) is mixed: four positive trials, seven with no difference.
Protocols
Surface or intra-anal pelvic floor EMG, fast and slow contraction exercises, adjunct electrical stimulation, daily home practice; 3-6 month programmes, 5 to 20 supervised sessions, optionally started before surgery.
Limits
The intervention is composite (exercises + EMG + electrical stimulation): the specific contribution of biofeedback is not isolated. The post-prostatectomy evidence is heterogeneous and most recent trials show no between-group difference; samples remain small (31 to 55) and the self-reported IIEF-5 dominates.
Study base
Two positive independent RCTs, two further perioperative RCTs and a growing body of uncontrolled studies. 2022-2026 base: four indexed publications on male sexual function (two systematic reviews, one retrospective cohort, one premature-ejaculation RCT).
Brendan's perspective
Level 5 maintained, and for once the number rests on what it should: two randomised trials from independent settings against active comparators — lifestyle counselling (Dorey 2004) and verbal instruction in pelvic-floor contraction (Prota 2012, 47 % versus 12.5 % potency recovery at 12 months) — with blinded assessment in Dorey. My reservation is about what is being rated. The intervention is composite (exercise, EMG, sometimes electrical stimulation), so the specific contribution of feedback is not isolated. And dose decides the result: two preoperative sessions give nothing (de Lira 2019), twelve weekly sessions do. Akdagcik 2026 bears this out after prostatectomy — four positive trials, seven with no between-group difference. This is not an indication I treat; I refer to a pelvic-floor physiotherapist. What a client should be told is that they are buying a supervised training programme with a measurement instrument in it, not a device effect.
