What was done
An observational study evaluated 122 men with isolated erectile dysfunction (ED) and 108 men with isolated premature ejaculation (PE) without neuromuscular disease or prior perineal rehabilitation. Participants received twenty 30-minute sessions of voluntary contractions combined with electrical stimulation to strengthen the ischiocavernosus muscle. Linear mixed-effects models analyzed indirect measurements of intracavernous pressure, specifically maximum contraction-generated pressure changes (ΔP) and maximum baseline plateau pressure during full erection.
What was found
Over 20 sessions, among participants showing positive trends, maximum ΔP increased in 87% of men with ED and 88% of men with PE, while maximum baseline pressure increased in 99% of men with ED and 72% of men with PE. Joint modeling estimated a mean expected intracavernous pressure progression of 62.85 cm H2O in ED and 64.15 cm H2O in PE after 5 sessions. No numerical clinical symptom scores or validated sexual function outcomes were reported in the abstract.
Why it matters
The findings demonstrate that targeted pelvic-floor rehabilitation can alter physiological pressure dynamics linked to penile rigidity, supporting further investigation of physical therapy for male sexual dysfunction.
Limits
The study lacked a randomized, sham, or untreated control group, preventing determination of causal efficacy. Intracavernous pressure and muscle force were measured indirectly rather than directly, and clinical outcomes for premature ejaculation were difficult to assess and not quantified in the abstract.
