Today in the clinic encountered a male patient, 35 years old, entered the consultation room and sat there dumbfounded, frustrated, half a day did not speak, after careful questioning, only slowly told his condition: the patient has been married for 5 years, the couple has a good relationship, in the process of each sexual life, although the penis can be erect, inserted into the vagina can continue to erect for more than 30 minutes, but no matter how long penetration or pumping can not reach In the process of each sexual intercourse, although the penis can be erect and can be erected for more than 30 minutes after vaginal penetration, but no matter how long the penetration or pumping can not reach orgasm and there is no ejaculation action, and can not experience the euphoria when ejaculation, and finally all end up with penis weakness. The ejaculation usually occurs during sleep on the night of sexual intercourse and is accompanied by euphoria. The patient reported that he usually masturbated and had orgasm and ejaculation during masturbation. His mother was very puzzled and repeatedly asked him about it. The patient was suffering from “non-ejaculation”, which is commonly known as “empty cannon”. In fact, this type of patient is not uncommon, but many people are ashamed to talk about it, avoiding the disease, they often suffer in silence due to sexual problems and infertility brought about by the trouble. As this disease is mainly seen in young adults, improper handling will also affect the relationship between husband and wife, and even lead to the breakup of the family, bringing mental anguish to the patient. Ejaculation is a complex physiological process, with nerve endings and central excitation being two important links. The reason for this is that the ejaculation center is inhibited by the cerebral cortex or the response threshold of the spinal ejaculation center is too high or the degree of stimulation is insufficient, so that the normal action of sexual intercourse cannot induce ejaculation, but there can be ejaculation or ejaculation can be induced by masturbation. The main causes of functional non-ejaculation are: the influence of various psychological factors, long-term rough masturbation, short penis, circumcision, loose vagina of wife, etc. 2, organic ejaculation: commonly caused by endocrine abnormalities such as pituitary tumors, spinal nerve injuries caused by various reasons, ejaculatory nervous system injuries caused by surgery such as prostate removal or rectal cancer, etc. The patient with organic ejaculation does not ejaculate during sex or in his sleep. 3, drug insemination: some drugs can affect the ejaculatory function, such as sedatives, sleeping pills, antidepressants, adrenergic receptor blockers such as guanethidine, phenothiazine drugs may have an inhibitory effect on the ejaculatory function. In this case, the patient did not take drugs that inhibit ejaculation, had no history of trauma to the brain and spinal cord nervous system, had no organic lesions that cause ejaculation such as pituitary tumors, had ejaculation during sleep at night, had orgasm during masturbation, and had ejaculation, so both organic and pharmacological ejaculation could be excluded. Functional ejaculation can be diagnosed as functional ejaculation. For ejaculation, especially functional ejaculation, which accounts for about 90% of cases, prevention is more important than treatment. Ejaculation is a complex physiological process in which nerve endings and central excitation are two important aspects, but the former is more important. Most of the patients with ejaculation are not excited enough due to the nerve endings, the key is that the stimulation threshold is too high and the intensity of stimulation is relatively too low to cross that “threshold”. Therefore, the most important thing is to provide technical guidance to the doctor, based on a detailed understanding of the patient’s condition, on how to enhance local stimulation. The application of sensual concentration means that the wife can induce ejaculation. Under the guidance of the doctor, the use of electric massagers to induce ejaculation can often achieve unexpected results. It has been reported that about half of the patients can return to normal in the first massage treatment, while some other patients can be cured by more than ten treatments. At the beginning, it takes 10-15 minutes of continuous stimulation, and later just 5 minutes to achieve the purpose of ejaculation. The stimulation area is mainly at the glans and tether, but can also be moved up and down along the penile shaft. The massager is both a high-grade massager used in hospitals (also known as electronic sperm extraction instrument), but also a variety of commercially available models of male health care massager. The doctor should educate the patient on sexual knowledge, so that they better understand the characteristics of the male and female response cycle, to dispel concerns, build confidence, and correctly grasp the skills of sexual life, which will often get better results. The doctor’s guidance is helpful for the patient to obtain successful ejaculation. Often, having one successful intravaginal ejaculation will permanently change the ejaculatory dysfunction. The harmony of the couple’s relationship will also be of great help in the treatment. Since the main contradiction in the performance of ejaculation in the couple’s relationship is in infertility, it is important to actively do a good job for the female partner, encourage her to try to accommodate the male partner, and take the initiative to cooperate to assist the male partner in treatment. Such as sexual life can take some measures to make the grinding phase of sassafras can strengthen the sexual stimulation, in order to make the male side to get a stronger sexual excitement, the female side should take the most appropriate position, and tightly embrace the male side, or consciously contract the vaginal sphincter to strengthen the stimulation of the penis. Chinese medicine treatment also often has a good effect, commonly used formulas are big ripe ground, Chinese wolfberry, Fubanzi, mulberry, cuscuta, shamrock, Wu Wei Zi. Western medicine treatment has not progressed much, mainly because most of the drugs used have large side effects and are difficult for patients to tolerate. The commonly used ones are ephedrine, levodopa, etc.
