Erectile dysfunction affects an estimated 30 million American men, and its prevalence increases with age — but it is not an inevitable part of aging, and it is not limited to oral medication. Modern men's health medicine offers a range of clinical, device-based, and hormonal treatments that address ED at its root cause rather than just managing it symptom-by-symptom. This guide covers the evidence-backed options available in 2026.
Understanding Erectile Dysfunction
An erection requires the coordinated function of blood vessels, nerves, hormones, and the smooth muscle of the corpora cavernosa. Dysfunction in any of these systems can impair erectile response. Understanding the underlying cause is essential for selecting the right treatment — what works for neurogenic ED (nerve-related) may not work well for vasculogenic ED (blood vessel-related), and vice versa.
Types of ED by Cause
Vasculogenic ED
The most common type. Reduced arterial blood flow or venous leakage impairs engorgement. Often associated with cardiovascular risk factors — hypertension, diabetes, smoking, high cholesterol.
Most Common (50–70%)Neurogenic ED
Nerve damage from prostate surgery, diabetes, spinal injury, or multiple sclerosis interrupts the nerve signals that trigger erections. VED and P-Shot therapy are especially relevant here.
Surgical / NerveHormonal ED
Low testosterone, elevated prolactin, or thyroid disorders can suppress libido and impair erectile function. A hormonal panel is a standard part of any ED workup.
Labs RequiredPsychogenic ED
Anxiety, depression, performance anxiety, or relationship issues. Often co-exists with physical ED, particularly in younger men. May respond well to treatment that also addresses the physical component.
PsychologicalClinical ED Treatment Options
These therapies are performed in a clinical setting under physician supervision. They represent the frontier of non-pharmaceutical ED treatment — targeting the underlying vascular and tissue causes rather than producing temporary pharmacological effects.
Acoustic Wave Therapy (Low-Intensity Shockwave Therapy)
Low-intensity extracorporeal shockwave therapy (Li-ESWT) — marketed as GAINSWave, Rejuvawwave, and similar brand names — uses focused acoustic pulses delivered to penile tissue to stimulate angiogenesis (new blood vessel formation) and activate resident stem cells. Unlike PDE5 inhibitors which only manage symptoms, AWT works at the cellular level to restore natural erectile function over time.
What the Evidence Shows for AWT + ED
- Multiple randomized controlled trials demonstrate statistically significant improvement in IIEF (International Index of Erectile Function) scores in men with mild to moderate vasculogenic ED.
- A 2019 meta-analysis found AWT produced clinically meaningful erectile function improvement in 60–75% of treated patients vs. 30% for sham treatment.
- Effects typically persist for 12–24 months following a standard protocol of 6–12 sessions.
- Best evidence: men with documented vasculogenic ED who have suboptimal response to PDE5 inhibitors.
Standard protocols involve 6–12 sessions (2–3 per week) of 15–20 minutes each. No anesthesia, no downtime. Many men report initial improvement within 3–4 weeks of completing the protocol. AWT is frequently combined with P-Shot PRP for enhanced outcomes — this combination is the most common multi-modal ED protocol offered at men's health clinics.

The P-Shot uses the patient's own platelet-rich plasma — a concentrated extract of growth factors drawn from a routine blood sample — injected directly into the corpus cavernosum and glans. Growth factors including PDGF, VEGF, and TGF-β stimulate tissue repair, improve vascular supply, and may regenerate penile nerve tissue damaged by prostate surgery or diabetic neuropathy.
The P-Shot is not a first-line monotherapy for ED, but clinical data supports its use as part of a combination protocol — particularly for men with post-prostatectomy ED or diabetes-related ED where vascular and nerve damage are the primary factors. Most providers recommend an initial series of two injections 4–6 weeks apart, with maintenance treatments every 12–18 months.
P-Shot Clinical Evidence
- Gottfried et al. (2019): Pilot study of PRP injections in mild-to-moderate ED showed statistically significant IIEF improvement at 6 months with minimal adverse events.
- Matz et al. (2018): PRP in Peyronie's disease showed curvature reduction and pain improvement — relevant to men with ED complicated by Peyronie's.
- Best outcomes when combined with AWT; several multi-modal protocols report superior results versus either treatment alone.
FDA-Cleared Device Therapies for ED
Two device-based options have substantial clinical history for erectile dysfunction — one is FDA-cleared specifically for ED, the other plays an important role in post-surgical rehabilitation and as adjunct therapy.
Vacuum Erection Devices (VEDs / Penis Pumps)
Vacuum erection devices are the only FDA-cleared mechanical treatment for erectile dysfunction and have been first-line therapy since the 1970s. A cylinder is placed over the penis, negative pressure draws blood into the erectile tissue to produce an erection, and a constriction ring at the base maintains it during sexual activity.
VEDs are particularly recommended for:
- Post-prostatectomy rehabilitation — Early VED use after radical prostatectomy is a standard urological protocol to maintain penile length, oxygenate erectile tissue, and support nerve recovery during the healing period.
- Men who cannot take PDE5 inhibitors — Those on nitrate medications or with certain cardiac conditions for whom Viagra/Cialis is contraindicated.
- Peyronie's disease management — Some urologists recommend VED therapy alongside other treatments to help maintain penile tissue health and reduce curvature progression.
Patient satisfaction in clinical populations ranges from 68–90% when devices are used correctly with proper patient education. The most common issues are suboptimal technique — using excessive pressure or wearing the constriction ring too long.
Read the Complete VED / Pump GuidePenile Traction Therapy — Adjunct Role in ED
Penile traction devices (PTDs) are not a primary ED treatment, but they play a specific role in certain ED contexts: post-prostatectomy patients who are experiencing ED with penile shortening use traction alongside VED therapy to maintain length during nerve recovery. Men with Peyronie's disease — where penile curvature complicates and worsens erectile function — also benefit from traction as part of a Peyronie's protocol. If traction is relevant to your situation, work with a urologist to establish a protocol.
Penile Traction Research GuideTestosterone and Hormonal Factors in ED
Testosterone is the primary male androgen and plays a central role in libido, energy, mood, and the cascade of physiological signals that initiate and sustain erections. Men with clinically low testosterone (hypogonadism — generally defined as total testosterone below 300 ng/dL with symptoms) frequently experience ED as part of a broader symptom cluster that includes fatigue, reduced libido, decreased muscle mass, and mood changes.
Testosterone replacement therapy (TRT) — delivered as injections, topical gel, or subcutaneous pellets — can significantly improve erectile function in hypogonadal men. Crucially, in men who are both hypogonadal AND have vasculogenic ED, TRT alone is often insufficient — the vascular dysfunction needs to be addressed alongside hormonal optimization for full response. This is why many men's health clinics now offer multi-modal protocols combining TRT, AWT, and P-Shot.
If you suspect low testosterone is a factor in your ED, a men's health clinic or urologist can order the appropriate blood panel and discuss whether TRT is appropriate for your situation.

Vasculogenic ED — the most common type — shares root causes with cardiovascular disease. The same lifestyle factors that damage arteries generally impair erectile function, and the same interventions that improve cardiovascular health frequently improve erectile function as well.
- Exercise: Regular aerobic exercise (150+ minutes per week) is one of the most evidence-supported interventions for ED, improving vascular function, reducing blood pressure, and improving testosterone levels.
- Weight management: Obesity is a strong independent risk factor for ED. Even modest weight loss in overweight men often produces meaningful improvement in erectile function.
- Smoking cessation: Smoking directly damages the endothelial lining of blood vessels and is a major contributor to vasculogenic ED. Cessation is one of the single most impactful steps a man with ED can take.
- Alcohol moderation: Heavy alcohol use acutely and chronically impairs erectile function. Reducing intake to moderate levels is associated with improved outcomes.
- Sleep quality: Sleep is when the majority of testosterone production occurs. Obstructive sleep apnea — common in overweight men — is strongly associated with both low testosterone and ED. Treating sleep apnea often produces significant improvement in both.
- Cardiovascular management: Treating hypertension, diabetes, and high cholesterol is essential. These conditions directly damage the vascular supply to the penis.
Lifestyle modification amplifies the effects of clinical treatment. Men undergoing AWT or P-Shot therapy who simultaneously improve cardiovascular risk factors typically see better and more sustained outcomes than those who don't.
Finding a Qualified ED Specialist
The quality and training of the provider matters significantly for ED treatments that require clinical skill — particularly AWT protocol design, P-Shot injection technique, and hormonal management. When evaluating a provider:
- Board certification — Look for board-certified urologists, or internal medicine / family medicine physicians with documented focus in men's health and sexual medicine.
- Experience with the specific therapy — How many AWT sessions have they performed? What outcomes do they track? Do they use validated tools like the IIEF questionnaire to measure progress?
- Comprehensive evaluation — A quality ED provider starts with bloodwork and health history, not just a sales pitch for their preferred protocol.
- Multi-modal thinking — The best outcomes typically come from combining therapies (e.g., AWT + P-Shot, or TRT + AWT). Providers who offer only one treatment should be viewed skeptically.
- Transparent pricing — Quality providers give clear pricing upfront. Avoid clinics that use aggressive upselling or create urgency around treatment decisions.

What is the most effective treatment for erectile dysfunction?
The most effective treatment depends on the underlying cause. For vasculogenic ED (the most common type), acoustic wave therapy has strong clinical evidence for addressing root-cause vascular insufficiency. PDE5 inhibitors (prescription medications) remain the most widely used first-line treatment. For men who don't respond to medications, or who prefer non-pharmaceutical options, AWT combined with P-Shot PRP represents the most evidence-based combination currently available at men's health clinics. A proper evaluation by a urologist is the right starting point.
Does acoustic wave therapy actually work for erectile dysfunction?
Yes, for appropriately selected patients. Multiple randomized controlled trials support Li-ESWT for mild to moderate vasculogenic ED, with 60–75% of patients in studies reporting clinically meaningful improvement. The mechanism — stimulating new blood vessel growth — addresses the underlying vascular dysfunction rather than just enabling a temporary pharmacological effect. Results typically last 12–24 months after a standard protocol. It works best for men with documented vasculogenic ED; it is less effective for purely neurogenic or psychogenic ED.
Can a vacuum erection device (penis pump) treat erectile dysfunction?
Yes. VEDs are FDA-cleared for ED and have been prescribed by urologists for decades. They are especially valuable for post-prostatectomy patients as part of penile rehabilitation, and for men who cannot tolerate or are contraindicated for PDE5 inhibitors. Patient satisfaction is high (68–90% in clinical studies) when devices are used correctly. They do not address the underlying cause of ED, but they are a reliable tool for achieving erections sufficient for sexual activity.
What is the P-Shot and does it help erectile dysfunction?
The P-Shot (Priapus Shot) injects platelet-rich plasma from the patient's own blood into penile tissue. The growth factors in PRP stimulate tissue repair, improve vascular health, and may support nerve regeneration. Clinical data shows significant improvement in erectile function scores at 6 months, particularly for vascular-related ED. It works best as part of a protocol — typically combined with AWT — and is especially relevant for post-prostatectomy and diabetic ED where tissue-level damage is the primary factor.
Can low testosterone cause erectile dysfunction?
Yes. Low testosterone (hypogonadism) is a common contributing factor to ED — suppressing libido and impairing the hormonal signals that facilitate erections. TRT can improve erectile function in hypogonadal men, but vascular factors often co-exist and need to be addressed simultaneously. Any proper ED workup should include a hormonal blood panel to rule out or identify a testosterone deficiency.
Does insurance cover ED treatment?
Coverage varies. Prescription PDE5 inhibitors are sometimes covered for specific medical indications. VEDs may be covered when prescribed by a physician for documented ED (especially post-prostatectomy). Acoustic wave therapy, P-Shot PRP, and most men's health clinic procedures are typically not covered by insurance and are paid out of pocket. Always verify with your insurer before scheduling. Many clinics offer financing options for multi-session protocols.
