P-Shot vs penile implant surgery, when each is right

The P-Shot is the right starting point for the great majority of men with ED. Specifically:

• Mild-to-moderate ED of recent onset
• ED with tissue, vascular, or sensitivity components
• ED in men who have not yet tried PDE5 inhibitors thoroughly
• ED responsive to PDE5 inhibitors but where the man wants to reduce dependence
• ED with Peyronie's, post-prostate, or lichen-sclerosus components
• Any case where reversibility matters

Roughly 7 in 10 properly-selected P-Shot patients respond well. If you respond, you've avoided surgery. If you don't respond, you've lost the time and cost of the treatment but nothing about the tissue itself: surgery remains available if needed later.

Penile implant surgery is the right answer when:

• ED is severe, longstanding, and unresponsive to PDE5 inhibitors at maximum dose
• Regenerative treatments (PRP, shockwave) have been tried and failed
• Vacuum device and intracavernosal injection therapy are also unsuitable or have failed
• The cause is anatomical damage that regenerative biology cannot reverse (e.g. complete cavernous nerve injury, severe vascular damage with no preserved tissue)
• The patient is medically fit for surgery and accepts the trade-offs

For these patients, the implant is genuinely life-changing: reliable erections on demand, no medication needed, predictable long-term function. The trade-off is the surgery itself, the recovery, the loss of spontaneous physiological erection, and the small ongoing risk of mechanical complication.

We refer surgical candidates to specialist andrology surgeons. We do not perform implant surgery.

For most men, the rational sequence is:

1. Lifestyle and risk-factor optimisation (smoking, weight, exercise, blood pressure, diabetes control)

2. PDE5 inhibitors (Viagra, Cialis) used appropriately

3. The P-Shot or Enhanced protocol if PDE5 inhibitors are insufficient

4. Trial of vacuum device and/or intracavernosal injection therapy if regenerative treatment is partial

5. Penile implant surgery for severe treatment-resistant ED

Most men do not need step 5. Some do, and for them, surgery is the right answer, not a failure of earlier treatment.

Will the P-Shot delay surgery if I end up needing it? No. The P-Shot does not alter the anatomy in a way that affects subsequent surgical options. You can have surgery later if needed.

If the P-Shot fails, what next? We discuss next steps honestly. Typical pathways: optimisation of medication, trial of intracavernosal injection therapy, urological assessment for surgical candidacy.

Is the cost difference really 10x? Yes. UK private penile implant surgery typically costs £15,000 - £25,000+ including consultation, surgery, hospital stay, and follow-ups. The P-Shot at £1,250 is roughly an order of magnitude cheaper, which is why trying regenerative treatment first usually makes economic sense as well as clinical sense.

Does the NHS offer implant surgery? Yes, in some cases, through urology referral, with strict eligibility criteria including failure of conservative management. NHS waiting times vary by trust.

Can I have the P-Shot if I've already had an implant? PRP injection into a corpus cavernosum containing a prosthesis is not standard practice and is not something we perform. PRP for other conditions (Peyronie's, lichen sclerosus, glans sensitivity) can sometimes be appropriate post-implant: discuss at consultation.
