What Is the P-Shot (PRP Injection) for ED? How It Works

The Priapus Shot®, commonly known as the P-Shot, is a cutting-edge, non-surgical treatment for erectile dysfunction (ED) that uses a man’s own platelet-rich plasma (PRP) to enhance sexual performance, improve penile function, and promote tissue regeneration.

It has gained popularity among men seeking a natural, drug-free solution to ED, as well as those who want to enhance sensitivity, firmness, and stamina.


🔬 What Is Platelet-Rich Plasma (PRP)?

PRP is a concentration of platelets and growth factors derived from your own blood. Platelets play a crucial role in healing and tissue regeneration by releasing bioactive proteins that:

  • Stimulate new blood vessel formation (angiogenesis)
  • Promote collagen and elastin production
  • Repair damaged tissues and nerves

By isolating and injecting this concentrated plasma into specific areas of the penis, the P-Shot helps revitalize erectile tissues and restore natural function.


🧪 How the P-Shot Works for ED

Here’s a step-by-step breakdown of how the P-Shot works:

1. Blood Draw and PRP Processing

  • A small amount of blood is drawn from your arm (like a routine lab test).
  • The sample is placed in a centrifuge, which spins it to separate PRP from red and white blood cells.
  • The resulting PRP is then collected into a syringe for injection.

2. Numbing and Preparation

  • A topical numbing cream or local anesthetic is applied to the penis to minimize discomfort.
  • The area is cleaned and prepped for the injection.

3. Injection of PRP

  • The PRP is injected into strategic areas of the penile shaft and corpus cavernosum (erectile tissue).
  • This stimulates cell regeneration, improved blood flow, and nerve sensitivity.

4. Optional Use of a Vacuum Erection Device (VED)

  • Some protocols include using a penis pump right after the procedure and for several weeks after to help shape tissue and enhance results.

🌟 Benefits of the P-Shot

Many men experience positive effects in just a few weeks, with ongoing improvements over several months. Benefits may include:

✅ Stronger, firmer erections
✅ Improved blood flow to the penis
✅ Increased sensitivity and sensation
✅ Enhanced sexual stamina
✅ Better response to ED medications
✅ Possible penile length and girth enhancement
✅ Improved results in men with Peyronie’s disease (penile curvature)


🔬 The Science Behind PRP and ED

PRP therapy leverages the body’s natural healing mechanisms. In the penis, PRP:

  • Induces neovascularization (formation of new blood vessels)
  • Stimulates repair of smooth muscle and endothelial tissue
  • May regenerate nerve fibers, enhancing erectile signaling
  • Improves microcirculation within erectile tissues

These changes can restore erectile function in men with vasculogenic ED, nerve-related dysfunction, or age-related decline.


📊 Who Is a Good Candidate for the P-Shot?

Ideal for men who:

  • Have mild to moderate ED
  • Want a non-surgical, non-drug option
  • Do not respond well to PDE5 inhibitors (Viagra, Cialis)
  • Have conditions like diabetes, low testosterone, or poor circulation
  • Want to improve performance or sensation even without ED

Note: Severe ED due to extensive nerve damage (e.g., after prostate surgery) may require additional therapies.


⏳ How Long Does It Take to Work? How Long Do Results Last?

  • Onset: 3–6 weeks after injection
  • Peak effect: Around 3 months
  • Duration of results: Up to 12–18 months, depending on health and maintenance
  • Some men repeat the procedure annually or every 6–12 months for continued benefits

⚠️ Risks and Side Effects

Because PRP uses your own blood, the risk of allergic reaction or rejection is extremely low. However, mild side effects can include:

  • Temporary swelling or bruising at the injection site
  • Mild discomfort or sensitivity for 1–2 days
  • Rare risk of infection (very low if performed by a trained provider)

🏥 Is It Safe? Is It FDA-Approved?

The P-Shot® name is trademarked, and the treatment is off-label but widely used by urologists, sexual medicine specialists, and certified providers. The PRP process itself is FDA-cleared for use in other orthopedic and aesthetic procedures but not specifically approved for ED.


👨‍⚕️ What to Ask Your Provider

Before getting the P-Shot, ask:

  • Are you trained in the official P-Shot® protocol?
  • How many ED cases have you treated?
  • What outcomes have your patients seen?
  • Do you recommend combining this with other therapies (e.g., shockwave, TRT)?
  • What should I do before and after the injection?

📌 Final Thoughts: Is the P-Shot Right for You?

The P-Shot offers a promising, natural, and drug-free alternative for men struggling with ED or wanting to enhance their sexual performance. It’s especially useful for those with vascular or nerve-related issues, or those looking to restore penile function without the side effects of medication.

When performed by a skilled provider, it’s safe, minimally invasive, and offers lasting improvements in sexual health.
