The principles of this type of surgery are through increasing the pressure and the area over the G-Spot to stimulate and lead to orgasm. Many women have sexual dysfunctions because their G-Spots are unclearly or too deeply located, so that when they are having sexual intercourse, no matter how hard their partners try, they are unable to stimulate the G-Spot and lead to orgasms. So we try to improve this kind of sexual dysfunction through inserting a spherical object above the G-Spot and exerting pressure.
