During this virtually painless procedure, a numbing cream is applied to the vagina and the arm. Blood is drawn from the arm in the same way as with any blood test. Then, using a centrifuge and a special method, platelet rich plasma (PRP) is isolated, resulting in growth factors. Using a very thin needle, the growth factors are then injected into the clitoris, upper vagina and an area most important for the sexual response, the O-Spot.
