Treating Male Sexual Dysfunction with Pelvic Floor Muscle Exercises

Often pelvic floor therapists see men for post-prostatectomy urinary leakage. However, at least for me, that quickly led to seeing male patients for pelvic pain and sexual dysfunction. Male sexual dysfunction is a broad category and can consist of erectile dysfunction (ED), ejaculation disorders including premature ejaculation (PE), and low libido -- often there is a pelvic floor muscle (PFM) dysfunction component. Conservative treatment frequently consists of pharmacological and lifestyle changes for this population.

In normal sexual function, the male superficial pelvic floor musculature (bulbocavernosus and ischiocavernosus) work together to create increased intracavernosus pressure by limiting venous return, resulting in an erection. Ejaculation is created by rhythmic contractions of the bulbocavernosus muscle.

The authors of this systematic review were curious if pelvic floor muscle training was effective for treating erectile dysfunction and premature ejaculation diagnoses, and if so to determine whether there is a treatment protocol. Ten studies were found that met the inclusion criteria, five that focused on ED and five that focused on PE. In total, there were 668 participants ranging in age from 30-59 years old. Studies were excluded if participants were post-prostatectomy and/or had a neurological diagnosis. The intervention was a pelvic floor program, and pelvic floor muscle contractions were either taught or supervised. Studies also included supportive treatment including biofeedback, lifestyle changes, and electrical stimulation.

The studies focused on erectile dysfunction listed a combination of hormonal, psychogenic, arteriogenic, and venogenic causes. The pelvic floor training ranged from 5-20 visits over 3-4 months and included a home exercise program. Pelvic floor training was similar in all studies and consisted of maximal quick contractions over one second and submaximal endurance holds over 6-10 seconds. Compliance to home exercise program was not assessed. Between 35% and 47% of participants reported a full resolution of symptoms. Subjective improvements were supported by improved maximal anal pressure and intracavernosus pressure. One study used the International Index of Erectile Function (IIEF) and showed significant improvement (p<0.05).

The studies focused on premature ejaculation noted participants had either lifelong or secondary PE. The pelvic floor training in these studies ranged from 12-20 sessions over 1-3 months. All studies used electrical stimulation as part of the pelvic floor muscle training. Four studies also used biofeedback. Only one study listed a home exercise program but did not report on compliance. The pelvic floor muscle training was compared to nothing in three studies, and to a selective serotonin reuptake inhibitor (SSRI) in the other two studies. Patient reported full resolution of symptoms was 55-83% in two studies, and there was a significant improvement in delay in heterosexual penetrative ejaculation (p<0.05) in three studies.

For both erectile dysfunction and premature ejaculation, pelvic floor muscle exercise prescription was 2-3 times per week with pelvic floor muscle contractions both maximal quick contractions and submaximal endurance holds. Significant results were shown with participants who were taught pelvic floor muscle contractions through a combination of verbal and physical means (typically biofeedback). Specific verbal cues were not reported. The authors suggest that electrical stimulation was helpful for training recruitment patterns; however, there was not a significant difference in outcomes for those with ED when using electrical stimulation. The authors suggest that pelvic floor muscle training can be part of a conservative treatment. It may be used with oral pharmacology for quick results, and may be beneficial with electrical stimulation and biofeedback, though more research is indicated.
