What is the Priapus Shot ® (P-Shot®)?

The P-Shot ® is a novel, non-surgical treatment option for ED. Dr. Ota was trained by the inventor of the procedure, Dr. Charles Runels. The procedure involves the use of your own platelet-rich plasma (PRP) which is injected into two main anatomical sections of the penis: 1) the bilateral corpus cavernosum (shaft of the penis) and 2) the glans penis (head of the penis). Although this may sound painful, the injections are well-tolerated as the skin of the penis is anesthetized with topical numbing cream. Dr. Ota uses a very small needle to perform the series of 5 injections. After the injections are completed, a vacuum device is applied to the penis for 10 minutes on a low and painless setting. The vacuum applications is important to help distribute and maintain the rejuvenating and repairing effects of the growth factors and cytokines that are present in the activated PRP. 
Although this P-Shot ® procedure is not yet approved by the FDA, the PRP kit system that Dr. Ota uses for this procedure is FDA approved. Many physicians around the world perform the P-Shot ® and are seeing success with many of their patients with ED. 

Who is a good candidate for the P-Shot ®?

Typicaly, the best candidates for the P-Shot ® are men that are experiencing mild-to-moderate symptoms of ED. To determine your ED severity, print and complete the International Index of Erectile Function Scale (IIEF)
During your consultation, Dr. Ota will go over the results of this scale and your treatment options. 
Unfortunately, the P-Shot ® does not work for everyone. In some cases, one treatment will result in satisfactory results. In other cases, 2-3 treatments may be necessary. 

What are some of the possible clinical benefits of the P-Shot ®?

–       Improved erections

–       Improvements with Peyronie’s Disease 
–       In some cases, increased length and girth of penis
