When men research the P-Shot® (Priapus Shot) for erectile function or sexual wellness, one question frequently arises: "Can it increase my size?"
The short clinical answer is: The P-Shot® has not been shown to reliably increase anatomical penile length or girth. Any change in erection fullness or perceived dimensions reflects improved microvascular blood flow and optimal erectile rigidity rather than permanent anatomical tissue enlargement. The American Urological Association (AUA) reports no established evidence for PRP injections as a penile girth enhancement procedure.
The Science of Erection Size
To understand how the P-Shot® affects size, we must first look at what dictates the size of an erection. An erection occurs when the corpus cavernosum (the sponge-like cylinders in the penis) fill with blood.
As men age, or due to underlying health conditions (like diabetes or cardiovascular issues), two things frequently happen:
Decreased Blood Flow
Micro-vessels become compromised or blocked, meaning less blood can physically enter the penis.
Loss of Elasticity
The tissue itself loses its elasticity and collagen structure over time, preventing it from expanding to its full, natural capacity.
Because of these factors, many men are not actually achieving their *maximum natural size* when they get an erection. They are experiencing "sub-optimal" erections, which can make the penis appear visually smaller and feel less girthy than it did in their younger years.
How the P-Shot® Relates to Size
The P-Shot® utilizes Platelet-Rich Plasma (PRP) extracted from your own blood. When this PRP is injected, the concentrated growth factors trigger neovascularization (the creation of new blood vessels) and tissue repair. Here is how this translates to size:
1. Enhancing Blood Capacity (Girth)
By building a stronger, healthier vascular network, the P-Shot® allows significantly more blood to enter the corpus cavernosum during arousal. This increased volume directly translates to a firmer, harder erection. Because the chambers are filling more completely and with higher pressure, men frequently report a noticeable increase in girth.
2. Tissue Rejuvenation (Length)
The growth factors in PRP are studied for supporting local vascular health and tissue elasticity. By restoring healthy blood flow and tissue responsiveness, the penis can achieve its full, natural length and fullness during an erection.
The Key Takeaway
The P-Shot® is designed to support microvascular health and erectile responsiveness—not to expand anatomical penile dimensions. In responsive men, improvements in cavernous blood pooling and firmness can make erections feel fuller and more rigid, but it should not be viewed as an enlargement procedure.
Vacuum Erection Devices (VED) in Post-Procedure Care
In select patients, Dr. Nina Gupta may discuss the temporary use of a medical-grade Vacuum Erection Device (VED) as part of post-procedure tissue conditioning.
When recommended, vacuum therapy is utilized for specific clinical purposes:
-
Tissue Conditioning: Gentle negative pressure draws fresh blood into the corporal bodies to encourage tissue elasticity and vascular compliance.
-
Realistic Expectations: A vacuum device does not accelerate cellular growth or physically redistribute growth factors; rather, it is a complementary mechanical tool used strictly under physician guidance to support circulation.
A Comprehensive Approach to Erectile Health
For men with vasculogenic erectile dysfunction, combining targeted modalities often provides a more thorough approach than relying on a single treatment:
Coordinating the biological signaling of the P-Shot® with low-intensity Acoustic Wave Therapy (investigated for promoting local microvascular circulation) addresses erectile physiology from multiple angles. In addition, evaluating and optimizing serum hormones through Testosterone Replacement Therapy (TRT) ensures that systemic androgen balance supports healthy sexual desire and nocturnal erectile function.
Conclusion
While the P-Shot® is not a cosmetic penile enlargement procedure, it provides an evidence-based regenerative option evaluated for supporting microvascular health and erectile firmness. For men whose erections have lost rigidity or fullness over time, improved vascular perfusion helps restore dependable, natural erectile quality.
