Zhou Shaohu, an associate professor of urology in the First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine, said that "water bath" health care is very similar to their "negative pressure suction massage therapy". The principle is to fill the cavernous body of male penis, expand the cavernous body and improve blood circulation through negative pressure suction and steam massage.

"First of all, put the penis in a vessel, then inject clear water or corresponding therapeutic liquid (Chinese herbal medicine extract for tonifying kidney and strengthening yang, activating blood circulation and fixing sperm), and then vacuumize to cause negative pressure suction. Because the penis itself is full, it will expand itself under the suction of negative pressure, and then by changing the direction of water pressure or water flow, water or liquid medicine will be driven to churn (accompanied by bubbling bubbles), which can promote the increase of blood flow and oxygen content of the penis, thus achieving the effect of supplying nutrition. In addition, it can also cooperate with electromagnetic waves to stimulate meridians and acupoints around the penis to help restore erectile function. "

According to reports, the effective rate of negative pressure suction in the treatment of erectile dysfunction is 72%.

Xuan, an associate professor of urology and andrology in the Second Affiliated Hospital of Sun Yat-sen University, said that functional erectile dysfunction is more common in young people, while erectile dysfunction in the elderly is mainly organic, which is usually a precursor to complications, complications or other physical diseases. The former needs to build confidence, while the latter needs adjuvant treatment for other diseases. If you just bathe and massage your genitals, I'm afraid the effect is not great. However, negative pressure suction will hinder venous return and cause endothelial cell damage after increasing blood supply to penis. Short-term treatment is effective, long-term treatment may aggravate the obstacle, and emergency use should be interrupted.

"We have an' external counterpulsation' therapy to promote sexual function by improving the function of the whole body organs. It mainly uses airbags wrapped in human limbs and buttocks to exert external force on the human body during diastolic period, driving the blood of lower limbs and buttocks to return to the aorta, thus accelerating the blood circulation of the penis, promoting metabolism and restoring the function of the corpus cavernosum. "

Xuan said that external counterpulsation therapy starts from the root of the disease, and most young people can improve it once or twice. In addition to ischemia, the general condition of middle-aged and elderly people will also be significantly improved.

Although experts of Chinese and Western medicine have different views on "root bath" health care, they all think that both "negative pressure suction" and "external counterpulsation" treatment are only applicable to male sexual dysfunction. "In the final analysis, it is used to treat diseases, so it should be operated by medical staff in regular hospitals."

Jian Huang, vice president of the Second Affiliated Hospital of Sun Yat-sen University and professor of urology, said that normal male penile erection is not a problem at all, and there is no need to seek additional stimulation. "If necessary, you can achieve your goal through foreplay or masturbation." Moreover, men with sexual dysfunction should be treated differently. "Many male sexual dysfunction is often caused by psychological factors. For example, patients with psychological impotence always feel that they can't. If you can witness the full erection of the penis during the treatment, it will inevitably build confidence and improve sexual function. However, if there is organic sexual dysfunction, such as vascular impotence, the penis has cavernous vein leakage, which can never swell like a puncture, or there is erectile nerve injury, or sexual apathy caused by abnormal sex hormones, then no matter what,' attraction' or' counterpulsation' will have no effect. "

Zhou Shaohu said that negative pressure suction and acupoint massage are aimed at treatment, and their targets should be patients with impotence, premature ejaculation, no ejaculation and short penis, especially middle-aged and elderly people with weakened spontaneous erection at night, which is conducive to slowing down the recession and also has the effect of psychotherapy.
