P Shot

The platelets in our blood do far more than allow our blood to clot after a wound: they also have various growth factors and stem cells that kick start the entire skin healing process. For a couple of decades, professional athletes have put these growth factors to work helping them heal more quickly after injury or surgery through injections of platelet-rich plasma. Platelet-rich plasma starts with a typical blood sample, which is then placed in a centrifuge to separate out and remove the red blood cells. What’s left is a concentrated serum, platelet-rich plasma.

The Priapus Shot delivers the same healing properties to the penis. We now offer the Priapus Shot at Northwest Women’s Center. This is a complement to O-Shot we already offer for women.

What Is The P Shot?

The Priapus Shot, P-Shot for short, is named for Priapus, the Greek god of virility. The P-Shot uses a patient’s own blood platelets, white blood cells, and stem cells to improve penile function. It utilizes the healing and regeneration power of platelets, stimulating new tissue growth, and increased blood flow.


The P-Shot procedure is a fast, painless injection intended for men who have lost function due to an enlarged prostate, prostate cancer, drug side effects, conditions such as diabetes, or the after-effects from surgery. The P Shot can also be an effective treatment for erectile dysfunction.

Who Is A Good Candidate For The Priapus Shot?

Men with erectile dysfunction (ED) can be helped immensely by the P-Shot. It’s estimated that 15-30 million American men have ED. Beyond having ED, most men have problems with their erections from time to time, particularly as they enter middle age. This can cause issues with relationships and self-esteem.

Also, the P-Shot can help men with various physical problems, such as an enlarged prostate or diabetes. It can also counteract certain drug reactions and the adverse effects following prostate cancer treatment.


As mentioned above, at Northwest Women’s Center, we offer the P-Shot and the O-Shot (for women) to improve the relationships of our patients and their partners.

How Is The P Shot Procedure Done?

The process starts by taking a typical blood sample. The blood is placed into a centrifuge that separates out the platelets, stem cells, plasma, and white blood cells, but removes the red blood cells. What is left is super-concentrated platelet-rich plasma (PRP) that has extensive healing and regeneration capabilities.

Next, we apply local numbing anesthetic to your penis, and then inject the PRP into the various parts of your penis that are critical to sexual arousal and erectile function. The entire process takes around 30 minutes.

In addition to the P-Shot, we also provide you with a vacuum penis pump. After you receive the P-Shot, you use this pump to stretch the tissues of your penis. This pumping action stimulates the PRP and other ingredients in the P-Shot to initiate the regenerative process, and it can help increase girth and length.

How Long Before I See Results From The P Shot?

Beautiful coupleThese PRP injections provide immediate results. These results are variable between patients, but patients can expect improvement in erection quality and duration. As the growth factors and stem cells work, many patients can also expect a noticeable increase in size, but this takes a few weeks for the tissue regeneration to build.


Will I Still Need To Use ED Medications After The Priapus Shot?

Most patients receiving the P-Shot will no longer need erectile dysfunction medication, but this can vary by the patient. Circulation is the key, and some patients simply have decreased blood flow that is causing dysfunction. If it doesn’t completely remove the need for medication, the P-Shot should reduce the need.

Is The P Shot Painful?

There is no pain involved. We use topical lidocaine to make the penis numb prior to injecting the PRP. Plus, these injections are done with very small needles and they are not made to great depth in the penis tissue.

What Are The Side Effects Of The Priapus Shot?

Platelet-rich plasma is made from your own blood, so when it is reinjected in the P-Shot, there aren’t any side effects or reactions. This is a simple procedure with impressive results.

How Many P Shots Will I Need?

Generally, this is a one-time procedure. Results will usually last a year or more. If at that time you feel your function is declining again, another P-Shot would maintain your results.
