This technique is mainly targeted for patients who have never experienced a G-spot orgasm or who are uncertain about the suitability of surgical emplacement as they utilize a rapid and simple injection to ascertain the possible location of the G-spot and test the presence of a G-spot orgasm by themselves, thus facilitating reference and judgment for subsequent surgical correction. Regarding injection materials, purified fats harvested from other body parts or high molecular weight hyaluronic acid (Sub-Q) readily available are optional. The G-spot injection highlights the prediction of G-spot location and existence. Dr. Chuang will first visually predict and localize the G-spot location and then inject adequate fat cells or hyaluronic acid into the inferior vaginal mucosa around the G-spot. Then, the injection site will immediately present obvious prominence and dilation to facilitate the male genitals in stimulating the G-spot during sexual intercourse, thus increasing the probability of a female orgasm. Nevertheless, the fats or hyaluronic acid injected into G-spot may rapidly diminish in effect due to friction or the compression of sexual behaviors, and the results prolong for approximately 4–6 months on average; therefore, patients need to receive repeated injections or undergo relatively long-acting G-spot implantation surgery if they want to maintain the effect.
