Latest Treatments for Erectile Dysfunction

New treatments for erectile dysfunction are expanding beyond the established PDE5 inhibitors (sildenafil, tadalafil, vardenafil) that have dominated ED therapy since 1998. While oral medications remain the first-line approach for most men, several emerging therapies target the underlying vascular and tissue mechanisms of ED. This article reviews current evidence for low-intensity shockwave therapy, platelet-rich plasma (PRP), penile injections, vacuum devices, and surgical implants — distinguishing between treatments with robust clinical support and those still in experimental stages.

Low-Intensity Extracorporeal Shockwave Therapy (LiESWT)

Shockwave therapy uses acoustic pulses directed at the penile tissue to stimulate angiogenesis — the growth of new blood vessels — and improve endothelial function. Several meta-analyses of randomised controlled trials have shown modest improvements in erectile function scores (IIEF-EF) and penile blood flow parameters in men with vasculogenic ED.

Current evidence suggests that LiESWT may be most effective for men with mild-to-moderate ED who have some residual vascular function. Treatment protocols typically involve 6–12 sessions over 6–9 weeks. The therapy is non-invasive, painless, and has no reported systemic side effects. However, it is not yet recommended by major urological guidelines (EAU, AUA) as a standard treatment, and long-term durability of results remains uncertain.

Platelet-Rich Plasma (PRP) Therapy

PRP therapy — sometimes marketed as the "P-Shot" — involves injecting concentrated growth factors from the patient's own blood into the penile tissue. The hypothesis is that these growth factors promote tissue repair, neovascularisation, and nerve regeneration.

Current evidence for PRP in ED is limited to small, uncontrolled studies. No large randomised controlled trial has demonstrated statistically significant superiority over placebo. The therapy is not FDA-approved or NICE-recommended for ED. Men considering PRP should be aware that it is offered primarily in private clinics at significant cost, and the evidence base does not yet support its routine use.

Intracavernosal Injections

For men who do not respond to oral PDE5 inhibitors, intracavernosal injection therapy is the established second-line treatment. Alprostadil (prostaglandin E1) is injected directly into the corpus cavernosum, producing an erection within 5–15 minutes that lasts 30–60 minutes regardless of sexual stimulation.

Combination injections ("trimix") containing alprostadil, papaverine, and phentolamine can be used when single-agent alprostadil is insufficient. Response rates exceed 85% — significantly higher than oral therapy. The main barriers to adoption are the injection itself (needle anxiety) and the risk of priapism if the dose is too high.

Vacuum Erection Devices (VEDs)

Vacuum devices create negative pressure around the penis, drawing blood into the corpora cavernosa. A constriction ring is then placed at the base to maintain the erection. VEDs are non-pharmacological, have no drug interactions, and are particularly useful for men who cannot take PDE5 inhibitors due to nitrate use or other contraindications.

They are also a key component of penile rehabilitation programmes after prostate surgery. For detailed guidance on post-prostatectomy erectile recovery, see Can Cialis Restore Erectile Function After Prostatectomy?.

Penile Prosthesis (Surgical Implant)

For men with refractory ED who have failed all other treatments, a penile prosthesis (inflatable or semi-rigid) is the definitive third-line option. Patient satisfaction rates exceed 90% in published surgical series — the highest of any ED treatment. The inflatable three-piece prosthesis provides the most natural result: a concealed pump in the scrotum inflates cylinders within the corpora cavernosa on demand.

Implant surgery is irreversible — the natural erectile tissue is replaced during the procedure. It is reserved for men with severe organic ED and is typically performed by specialist urologists.

The Question of Cure

Most current ED treatments manage symptoms rather than reversing the underlying cause. However, for men whose ED is driven by modifiable risk factors — obesity, sedentary lifestyle, smoking, or uncontrolled diabetes — lifestyle interventions can produce meaningful and sometimes complete recovery of erectile function. To understand when ED can genuinely be reversed versus when it requires ongoing treatment, see Does Viagra Cure Erectile Dysfunction?.

For men already using PDE5 inhibitors, drug interaction safety is a practical concern — particularly if also managing BPH or hypertension.
