1, the definition of premature ejaculation
The most commonly used definition is that of the American Psychiatric Association and the World Health Organization, with the former defining premature ejaculation as “persistent or periodic minimal stimulation before insertion. Ejaculation during or shortly after insertion and before the individual’s will causes significant pain or affects the partner relationship.” The latter defines premature ejaculation as “the inability to delay ejaculation with full enjoyment of lovemaking, as evidenced by one of the following.
(1) Ejaculation before or soon after the onset of intercourse (within 15 seconds) ;
(2) Ejaculation occurs before reaching a full erection for sexual intercourse, the difficulty is not caused by a prolonged lack of sexual intercourse.
2. Penile sensory hypersensitivity or excessive excitability of penile sensory nerves is one of the causes of premature ejaculation
Based on this theory, the purpose of treating premature ejaculation may be achieved by surgically cutting off part of the sensory nerve, causing a decrease in penile head sensitivity and a decrease in nerve impulse afferents, thus prolonging the time for the ejaculatory nerve to reach the excitement threshold. In China, Professor Zhang Chunying of the Second Affiliated Hospital of Harbin Medical University was the first to carry out this procedure in September 2001, and then the procedure was spread throughout the country, mostly limited to private male hospitals.
3. The efficacy and safety of the surgery has not been recognized by the industry
The results of domestic and foreign research on this surgery are contrary to each other, the limited domestic literature claims to have up to 90% efficiency, the efficiency of foreign literature is less than 50%, and there are many complications. Domestic academics are good at faking, you know.
The procedure, even as a research procedure, has the strictest indications in the best university hospitals in China, where the patient must also have the following conditions.
(1) Normal erectile function;
(2) Married or with a regular sexual partner, with a regular sexual life of >1 year;
(3) Severe premature ejaculation;
(4) No other organic factors;
(5) Normal psychological quality;
(6) Effective local anesthetic applied to the penis;
(7) Wearing condom is effective;
(8) conventional sexual behavior therapy > 2 months is still ineffective;
(9) Age <40 years old, or >40 years old with a strong desire for surgery.
The efficacy of dorsal penile nerve block is very imprecise, and the technique itself is not perfect, and at most it should be explored as scientific research with full consideration of the patient’s wishes but definitely not used for clinical promotion.
In addition to the common complications of penile surgery such as infection, bleeding and incisional splitting, dorsal penile nerve block is prone to some more serious complications such as penile numbness and erectile dysfunction (ED) if too many branches of the dorsal penile nerve are cut. In general, partial severance of the dorsal penile nerve branches does not affect erectile function, but it may cause numbness and a marked lack of sensation in the penis, which can diminish the function of reflex erection and affect the erectile function of the penis. Older men are themselves prone to ED, and the procedure should never be used in older people or in patients with premature ejaculation in combination with ED.
Dorsal nerve block of the penis is not mentioned in any textbook of urology.
The procedure, which was almost rejected in the industry, is widely used by private male hospitals and has become one of the main means of enrichment for private male hospitals. Patients with serious complications such as penile numbness and erectile dysfunction (ED) are common after surgery. Professor Zhang Chunying painfully concluded: I am the inventor of dorsal penile nerve selective dissection (sic), this surgery is only to treat patients with primary premature ejaculation, with strict surgical indications and scientific standards, but individual advertising hospitals in order to one-sided pursuit of economic benefits, many patients who should not do the surgery through improper means, cheated to do the surgery, resulting in lifelong regret, the doctor who did the surgery is Doctors are the black sheep of the team, the hospital also has an unshirkable responsibility, the main responsibility is also in the national health care regulatory departments do not work hard enough. Specially remind the sick patients, should open their eyes to consult, scientific treatment of their condition, can not be some moral corruption of the doctor fooled, choose the wrong treatment.
4, the international medical association in the latest “2014 premature ejaculation diagnosis and treatment guidelines” clearly pointed out that “dorsal penile nerve excision may lead to permanent loss of sexual function and is not recommended for premature ejaculation treatment”.
5, many private hospitals in order to improve profits, to solicit business, will use the channels of Baidu bidding ranking, spend money to buy keywords to improve the search ranking, so as to attract patients, this kind of false advertising is to eat the trust of the people of the junkie. Nearly half of Baidu’s advertising revenue comes from false medical advertising, when you open Baidu enter the disease keywords, the more the top ranked hospitals do not go!
6, premature ejaculation patients, please love your penis, to this as a gimmick to solicit patients, the dorsal nerve blocking penis as the first choice for treatment of male hospitals, firmly said: I do not do this surgery, I will never do!
7, premature ejaculation patients, please go to a regular hospital for consultation.
