Abstract
Abstract Introduction A study of a novel PRP protocol to increase penile length, girth, and function Intro: Various solutions have been utilized to increase penis size, including fillers, fat transfers, traction devices, suspensory ligament ligation, and silicon augmentation. None of these improve length, girth, function and are completely safe. PRP is an autologous source of growth factors. The RestoreX is a well-studied traction device. Vacuum erection devices provide a stimulus for circumferential penile growth. Nitric Oxide boosters improve blood flow and nighttime erections. Objective The P-Long Study aims to find a safe and reproducible way to increase the length, girth, and function of a normal male penis. Methods The study is IRB approved and patient consented. Inclusion criteria: healthy men aged 20 to 55 with normal erectile function (SHIM greater than 22) and no Peyronie’s Disease, previous penile interventions, or congenital penile issues. Measurement of penile length and girth were performed by the patient on an erect penis during self-stimulation at full tumescence with standard protocol and measuring instruments (transparent rigid ruler and flexible tape measure) and documented with digital images. No PDE-5 inhibitors or Trimix were used. Measurements were taken at baseline and once a month for six months. PRP was administered in the right and left corpora under ultrasound guidance once a month for six months using PureSpin double spin system (60cc blood drawn) Centrifuge technical data show an average platelet recovery of 84% and average concentration of 6.6 times that of the whole blood sample. Using this data, the injection of 10cc of PRP, assuming a starting platelet count of 250K/microliter, would contain approximately 1.65 billion platelets. Traction with RestoreX 20 minutes bid and suction with Joel Kaplan penis pump (pressure 5-10 for 12 minutes bid (1 minute x 2 and 5 minutes x 2.) Nitric Oxide boosting supplement (trade name AFFIRM) with a dose of 3 gm L-Citrulline and 1 gm beet extract (nitrate). Results 29 men have completed treatment. The mean age was 32 and mean baseline erect penile length was 5.70 and girth was 5.25. Erect penis length was 0.805 inch greater after six months from baseline (N=29, paired t-test t=13.641 p value=0.000). Circumference was 0.469 inch greater (N=29, paired t-test t=13.498 p value=0.000). Using a Likert scale, all participants reported better erectile function. Conclusions The P-Long Protocol is potentially a safe way to improve erect penile length 0.81 inches and girth 0.47 inches over a period of six months and subjectively improve function in a healthy penis. The P-Long Protocol does not require any synthetic injectables or foreign bodies or extensive penile traction. The P-Long Protocol ultrasound-guided PRP injection can be taught to urologists and sexual medicine practitioners. It does not preclude additional augmentation procedures and is potentially an acceptable first option for men interested in penile enhancement. This study provides a guide for expectations for growth for men using the protocol. The slope of the growth curve indicates possible continued growth with additional treatments.
