Dr. Robert Rubin offers P-Shot treatment at two locations in Florida:
P-Shot in Naples P-Shot in Tampa
Telemedicine consultations are available for patients across Florida, including the Tampa Bay Area, South Palm Beach, and North Broward.
The Priapus Shot® (P-Shot) is a non-surgical, drug-free procedure that uses platelet-rich plasma (PRP) derived from your own blood to restore and enhance male sexual function. Studies have shown that approximately 76% of erectile dysfunction symptoms improve with a single P-Shot treatment, with some studies also documenting a 10–20% increase in length and girth. Results can continue to develop for one to two years after treatment.
The procedure involves drawing a small volume of blood, centrifuging it to concentrate the growth-factor-rich platelets, and injecting that plasma directly into targeted tissue in the penis. Because the treatment uses your own biology rather than synthetic drugs, there is no risk of allergic reaction and no systemic side effects. Dr. Rubin's post-procedure protocol includes the use of a specialized pump to accelerate functional recovery and optimize results.
The P-Shot is effective for a range of male sexual health conditions, including:
Dr. Rubin begins every sexual health consultation with a functional medicine evaluation rather than treating the presenting symptom in isolation. Erectile dysfunction and reduced sexual function are frequently downstream of other conditions — hormone imbalances, cardiovascular factors, medication side effects, or metabolic issues — and identifying the underlying cause determines whether the P-Shot alone is sufficient or whether other components need to be part of the plan.
The evaluation covers hormone function, a full physical exam, medical and family history, and a review of current medications. From there, Dr. Rubin builds an individualized treatment plan. Depending on your findings, it may include:
No two plans are the same. The P-Shot is one of the most effective tools in Dr. Rubin's approach to male sexual health, but it works best when the treatment addresses the full picture.
Patients experience little to no pain. A topical numbing cream is applied to the treatment area before the procedure, and the injection itself is well-tolerated by most men.
Some men notice improvements within days. The full effect develops gradually over four to twelve weeks as the PRP stimulates tissue regeneration, with continued improvement possible for up to one to two years.
Results typically last one to two years. The procedure can be repeated when effects begin to diminish, and many men choose to do so as part of an ongoing sexual health maintenance program.
Studies show that approximately 76% of ED symptoms improve with a single treatment. Some men with more significant dysfunction benefit from a series of treatments. Dr. Rubin will outline the expected protocol at your consultation based on your specific condition.
Yes, and the combination is commonly recommended for men with more significant erectile dysfunction. Shockwave therapy promotes new blood vessel formation in penile tissue, while the P-Shot delivers growth factors that stimulate cellular regeneration. Together they address ED through complementary mechanisms.
Dr. Rubin is an Advanced Fellow in Sexual Health by the American Academy of Anti-Aging Medicine, and ABIM Board Certified in Internal Medicine and Geriatrics Medicine. He spent the first 25 years of his career in internal and geriatric medicine, earning recognition from Castle Connolly Medical as one of the "Top Doctors" in South Florida for four consecutive years.
After completing a fellowship in anti-aging and regenerative medicine, he transitioned fully to functional medicine. Over the past 15 years he has built a men's sexual health program grounded in evidence-based care — one that treats the causes of sexual dysfunction rather than the symptoms alone, and that takes the time conventional medicine rarely allows.
Private consultations are available at both clinics. All P-Shot appointments are handled with complete discretion.
