Title: Treatment of premature ejaculation using a laser beam
Inventor: LEE KYUNG YONG
IPC: A61N5/06
Filed: 2021-06-07
Abstract: The present invention relates to a treatment method of premature ejaculation (PE) using a laser beam. Usually, the PE is treated by cutting a nerve on a rear side of a glans penis of a man, which is a surgical method where a knife is used to cut or block a nerve. When the nerve is badly treated in the surgery, it can rather cause a problem or in any case, makes the penis more sensitive to worsen PE. According to the present invention, instead of the surgical method, the laser is used as a non-surgical method, wherein a laser beam is emitted to the glans penis or the skin of the genitals to damage the surface of the genital skin photothermally and cause light burn, thereby decreasing a sensational sensitivity of the genitals to treat the PE. The treatment method of the present invention is a non-surgical method with no bleeding, so the practice is simple, very safe, and convenient without a risk of infection.
