The P-shot or the Priapus shot was named after the Greek god of fertility. The shot was pioneered by Dr Charles Runels, an American MD who specialises in sexuality issues. The patient's blood is withdrawn, processed through a centrifuge to create platelet-rich plasma which contains growth factors. The process is used in sport medicine to rejuvenate torn ligaments. Dr Runels uses it to increase penis size by ten to 20 per cent and improve blood flow for a stronger, harder erection. Runels, the inventor of the Vampire Facelift says, "When I first started doing cosmetic procedures to sculpt the face, it occurred to me that it would be wonderful to do the same thing to the penis."
The physiological goal of Big Al’s program is to expand the spongy bodies of the penis — known as the corpora cavernosa and the corpus spongiosum — while simultaneously stretching the tunica that holds those spongy bodies and spreading the suspensory ligaments that anchor the penis to the pubis. Cell walls grow and expand with each exercise session, Big Al tells me, and the compound effect over time is increased length. “One-third to one-half of the entire length of the penile body is hidden behind the pubis,” he notes. “Lengthening exercises like the Side-to-Side Stretch permanently expand these ligaments, allowing more of the inner penis to be exposed, and thereby, lengthening the measurable portion of the penis.”
As previously noted, gaining weight can result in the penis appearing shorter because the base becomes buried in fat. Liposuction may be used to reduce the pubic fat pad to make the penis appear larger . Studies show that suprapubic liposuction is very safe and successful with minor or no complications when it is performed meticulously, and long with improving associated esthetic concerns, it may help improve self-esteem as well .
