First, the disease is not ejaculation, also known as ejaculatory inability, refers to the normal sexual desire, penis erection is normal, can maintain erection and sexual intercourse in the vagina for a period of time, or even a very long time, but there is no orgasm, and can not ejaculate. This disease is caused by the dysfunction of a certain link in the process of sexual physiological reflexes in which the central nervous system and the peripheral nervous system, the endocrine system and the reproductive organs are jointly involved, so that the stimulation of sexual arousal is not enough to produce the ejaculatory reflex. According to the famous western sexologist Masters and Johnson’s survey, 450 male sexual dysfunction patients, of which 17 are not ejaculation, accounting for 8%; Shanghai study reported 2087 cases of male infertility patients, not ejaculation accounted for 32.39%; more than 70% of these people are due to the lack of sexual knowledge and housekeeping methods incorrectly caused by the domestic masses of the lack of knowledge of the sex is quite alarming, it is worth drawing attention to. This shows that the degree of poor sexual knowledge among the domestic masses is quite alarming and deserves attention. According to the nature of the disease, this disease is divided into primary ejaculation and secondary ejaculation. Primary non-ejaculation is characterized by never having ejaculation no matter in the waking state or in the sleep, mostly caused by congenital organic diseases; this situation is relatively rare. Secondary non-ejaculation is more common, usually there are two cases: one is once had in the vagina ejaculation experience, due to some reasons and currently in the vagina can not ejaculate; the second is in the vagina can not ejaculate, and masturbation or other ways can ejaculate. Third, the cause of the causes of ejaculation are many reasons, mainly divided into two categories of functional and organic. Functional reasons for ejaculation are as follows: 1. Mental and emotional factors, also known as psychogenic ejaculation disorder, is clinically the most numerous. It is mainly a result of sexual dysfunction, the inhibition of the ejaculatory center is strengthened, and it is impossible to be excited. Sometimes there is a premonition of ejaculation, but it is extinguished instantly. The etiology are from the mental and psychological aspects, such as frequent masturbation before marriage, so that after marriage sexual intercourse can not reach enough strength and not ejaculation; from childhood to receive the education of sexual distortion into nasty, dirty, obscene things; or dissatisfied with their spouses, the loss of interest in the opposite sex, loss of libido, avoidance of sexual intercourse; some fear of his wife’s pregnancy after marriage, the long-term restraint of sex, the formation of non-ejaculation of the conditioned reflexes. 2, the lack of sexual knowledge: sexual intercourse posture is not right, or improper method, penis inserted into the vagina after stagnation, not friction or friction intensity is not enough, did not provoke or did not reach the ejaculation center excitement required intensity often lead to non-ejaculation. 3, female factors: female fear of pain during sexual intercourse, fear of pregnancy or sexual desire, limiting male twitching; female physical fitness is poor, bored with sexual activities, so that the male sexual impulse is frustrated. 4, drug factors: mainly because of taking drugs that affect sympathetic nervous tension, such as the treatment of hypertension guanethidine, rifampicin; treatment of neurasthenia or insomnia, such as Librium, methylthiopyridazine, phenothiazine drugs, monoamine oxidase inhibitors. Excessive use of bitter cold Chinese medicine, alcoholism can also cause ejaculation. 5, objective factors: such as housing is narrow, the environment is noisy, the formation of sexual inhibition; both sides of the work is different, the commute time is not the same, sexual activities are not coordinated. 6, anatomical factors: long foreskin, friction in the vagina, the penis head itchy; foreskin inlay, pain, sexual intercourse is forced to interrupt; severe seminal caruncle so that atrophic changes can not effectively participate in the ejaculation process. 7, other factors: too frequent sexual intercourse, overwork, excessive use of bitter cold Chinese medicine, alcoholism and other reasons can also cause ejaculation. Organic causes of ejaculation are mainly as follows: 1, genital anatomical abnormalities: congenital defects in the genitourinary tract, such as congenital lack of seminal vesicles, congenital absence of the vas deferens; injury or inflammation caused by the vas deferens, seminal vesicles, epididymis and other reproductive tract obstruction. 2.Neurological system lesions: such as cerebral lateral lobe disease and resection, spinal cord injury, lumbar sympathectomy, after pelvic radical surgery and so on. 3, endocrine hypocrisy: such as pituitary, gonadal, thyroid and other lesions. Clinical manifestations 1. Normal libido, normal penile erection. 2, no sexual climax and pleasure during sexual intercourse, i.e., there is no sense of paroxysmal twitching of the genitals during the process of sexual intercourse. 3.No random ejaculation action during sexual intercourse, no semen ejaculation. 4, Functional ejaculation with seminal emission, organic ejaculation without seminal emission. V. Differential Diagnosis: 1, retrograde ejaculation: the same as non-ejaculation is that there is no ejaculation of semen from the urethral urethra during sexual intercourse. However, the retrograde ejaculation of the sexual intercourse time is normal, sexual intercourse with orgasm, there is also ejaculation action, in the first post-coital urine white flocculent, microscopic examination can be seen in a large number of spermatozoa and fructose. 2, azoospermia: sexual intercourse, ejaculation and orgasm is normal, there is semen discharge, no sperm in the laboratory. 3.Abnormal erection of the penis: the penis continues to be erect for more than 6 hours, or even up to several days, even after ejaculation, it does not become soft, accompanied by penile pain. Sixth, the treatment of non-ejaculation 1, general treatment: (1) sexual knowledge education and psychological treatment: correct the wrong concept of sex, coordinate the relationship between husband and wife, encourage the woman to take the initiative to cooperate with the man to assist in the treatment; (2) to develop good habits, quit frequent masturbation; quit smoking and alcohol; increase nutrition, physical fitness, improve the quality of the whole body; (3) to strengthen the physical exercise, can be used in traditional fitness therapies, such as qigong, tai chi and so on, to maintain physical and mental well-being; (4) to strengthen physical exercise, can use traditional fitness therapy, such as qigong, tai chi, etc. (3) strengthen physical exercise, you can use traditional fitness therapy, such as qigong, tai chi, etc., to maintain a happy body and mind; (4) to improve the living room environment, create a good sexual environment; (5) circumcision of the foreskin long circumcision. 2, surgical treatment: organic ejaculation, most need surgical treatment. (1) Western medicine: use ephedrine, levodopa, strychnine, neostigmine, etc.; endocrine abnormalities use testosterone propionate, human chorionic gonadotropin and other drugs. (2) Chinese medicine treatment: it needs to be prescribed according to the patient’s specific situation. (4) Head acupuncture with acupuncture treatment: head acupuncture frontal paracentral three lines mainly; with Dahu, Sanyinjiao, plus Taichong, zhongyi through the qu bone; plus Taixi, Guanyuan through the zhongyi for those who are deficient. Daily or every other day, 10 times for a course of treatment. 5, electric vibration and electric stimulation therapy: the use of electric massager to stimulate the glans ligament to induce ejaculation, often can get better results. There are also reports of the effect of inserting electrodes into the rectum. Seven, expert opinion 1, not ejaculation can not only lead to infertility, long-term existence can even lead to changes in libido, erectile dysfunction. Therefore, it is necessary to pay attention to it and treat it actively. 2, the treatment of ejaculation, need the patient’s wife’s understanding and cooperation. Therefore, the wife should sympathize with her husband and give him more comfort, and it is advisable for the couple to seek medical treatment together and collaborate in the treatment. 3, both husband and wife should fully understand the anatomy and physiological function of the sexual organs, sexual reaction process knowledge, master the correct posture and method of sexual intercourse, so that the ejaculatory center by enough sexual stimulation. 4, behavioral therapy: sexual intercourse continue to increase the frequency and amplitude of the penis in the vagina, while the woman can control the contraction of the vaginal sphincter to increase the friction and the intensity of the stimulation of the penis, and with the hands of the scrotum pressed to the pubic symphysis of the male party, prompting the arrival of the male sexual climax to achieve the purpose of ejaculation. If you still can not achieve ejaculation, you can first set aside the penis out of the vagina, by the female hand for strong stimulation, when there is a sense of urgency to ejaculate, and then re-insert the penis into the vagina, and high-frequency large-scale lifting and insertion, until ejaculation. If the above methods still can not reach the vaginal ejaculation, you can masturbate yourself or by the female party to help, using the most stimulating way of sex, prompted by the vaginal ejaculation, to experience the feeling of ejaculation, and then use the above methods to gradually transition to the vaginal ejaculation. 5, organic ejaculation patients, drug treatment is ineffective. Therefore, patients who do not ejaculate are advised to first go to the specialties of regular public hospitals for vasovaginography and seminal vesicle imaging, or even CT or MRI and other imaging tests to clarify the cause of the disease. Otherwise, blind treatment is just a delay and a waste of money. 6.Functional ejaculation, Chinese medicine treatment has better efficacy (especially with acupuncture). However, the specific prescription and treatment plan need to be based on the patient’s specific situation and dialectic, and can not be treated with a fixed prescription of traditional Chinese medicine. Long-term treatment of ejaculation patients, may wish to try Chinese medicine therapy.
