With the increasing pressure of work life, environmental pollution and dietary structure changes, the delay of marriage and childbirth, because of male factors lead to more and more infertility patients. Among the many factors that cause male infertility, sexual dysfunction also accounts for a certain proportion, the common ones are: 1, insertion disorder: although sex is an animal and human instinct, but in actual life there are still many young couples simply can not complete sex, the husband’s penis can not enter the wife’s vagina – insertion disorder, in my outpatient In my clinic, I encounter 2-3 pairs of patients with penetration disorder every year. The most common causes of penetration disorder are the inability of women to cooperate properly, the tendency to resist during sex out of fear of pain and lack of sexual knowledge, and the difficulty of penetration and inability to complete sex if the man lacks sexual experience or has a hard enough erection. For penetration disorder, should strengthen the education of sexual knowledge, eliminate the fear of defensive psychology, behavioral training, men can use drugs to increase erectile hardness, local use of lubricants, if you can have a successful sex life, the problem is often solved. 2, erectile dysfunction: also commonly known as “impotence”, because the penis can not fully erect and can not complete sex life. Erectile dysfunction is related to psychology, emotions, stress, physical state, androgen levels, neurological and vascular function, most patients effective drug treatment, the most effective drugs are phosphodiesterase 5-type inhibitors, including tadalafil, sildenafil, vardenafil, etc. Tadalafil can be taken on demand, but also in small doses on time. Androgen supplementation and kidney aphrodisiac Chinese medicine can also play a certain effect. 3, ejaculation difficulties: sexual life can not reach orgasm to complete ejaculation, called ejaculation difficulties. Most of them can ejaculate during masturbation, but not during sexual intercourse; some are unable to ejaculate with specific objects; others are unable to ejaculate during masturbation and sexual intercourse. It can be treated by strengthening emotional communication, increasing the intensity of sexual stimulation, medication to improve libido and increase erectile hardness. 4. Reverse ejaculation: having orgasm and ejaculatory action during sex but no semen ejaculation is called reverse ejaculation, and the semen actually flows backwards into the bladder. The most common cause is diabetes. Certain drugs and surgery on the retroperitoneum and bladder neck can also lead to retrograde ejaculation. Retrograde ejaculation is poorly treated with medication and can be treated by collecting sperm in the urine for artificial insemination or “in vitro fertilization”. The majority of male infertility caused by sexual dysfunction can be solved by artificial insemination, and after completing childbirth and reducing the pressure, someone’s sexual dysfunction will get better.
