The problem occurs mainly because the diagnosis of primary premature ejaculation is not reached, it is not an indication for dorsal penile nerve selective excision, and the so-called dorsal penile nerve surgery is done on patients who should not be operated on without doing penile related examinations before the surgery, such as the ability of penile erection, penile sensitivity and the psychological state of the patient, just to earn dirty money. The efficiency of dorsal penile nerve selective excision for primary premature ejaculation can only reach about 92%, not 100%, when the indications for the surgery are strictly followed, and there may be surgical complications such as numbness of the penile head, incision pain, and incision infection for a short period of time. Theoretically, impotence will not occur after this surgery, and there is no impotence after this surgery in the thousands of patients we have treated. Characteristics of primary premature ejaculation: (a) Premature ejaculation occurs almost every time of sexual intercourse. (ii) It occurs during sexual intercourse with almost any sexual partner. (iii) It persists from the first sexual intercourse. (iv)The duration of sexual intercourse is within 30-60sec in the majority of cases. (v) Difficulty in the ability to delay ejaculation and low or lack of ability to inhibit the ejaculation of semen when ejaculation is imminent. Indications for surgery: Primary premature ejaculation or lifelong premature ejaculation. 1. Erection of the penis during sexual life consistently reaches grade IV hardness. 2.High penile head sensitivity. 3.The quality of sexual life seriously affects the couple’s relationship. 4.Voluntary abandonment of non-surgery. Patients who are ready to do dorsal penile nerve surgery must keep their eyes open to see the technical strength of the hospital you visit. It is best to trust regular public hospitals rather than private ones!
