The Priapus Shot® or P-Shot® as it is sometimes known, is a completely natural procedure that is non-surgical and painless. It involves the injection of platelet rich plasma into the shaft of the penis, once it has been sufficiently numbed. This attracts stem cells and growth factors that kick-start tissue growth in the nerves and blood vessels, that in turn improves the size and quality of your patient’s erections, as well as treating erectile dysfunction and Peyronie’s Disease.
