Male infertility is a condition in which a couple has lived together for more than one year without using any contraceptive measures, but the male partner causes infertility in the female partner. 2004 European Society of Reproduction statistics: 25% of couples of childbearing age cannot conceive within one year, and the male factor causes 50% of infertility. The causes of male infertility are sexual dysfunction (1.7%), varicocele (12.3%), reproductive tract infection (6.6%), congenital developmental abnormalities (2.1%) acquired diseases (2.6%), endocrine disorders (0.6%), immunological factors (3.1%), other abnormalities (3%), but up to 60%-75% of patients cannot find the cause, called idiopathic male infertility, who present only with abnormal sperm quality such as oligospermia, weak sperm and/or teratozoospermia. Unexplained male infertility may be due to a variety of factors, such as endocrine disruption due to chronic stressful environmental factors, reactive oxygen species and genetic defects. Male infertility can be partly avoided through prevention, there are several aspects of the individual can do: 1. Eliminate inbreeding especially those who have clearly one or both congenital or genetic defects should be firmly eliminated, which can not only reduce infertility, but also improve the quality of the birth population. Eliminate the influence of physical and chemical factors Avoid exposure to ionizing radiation and non-ionizing radiation, eliminate the warm state of the testicular area, maintain a normal microenvironment, reduce the reproductive immune response; minimize exposure to metal elements such as cadmium, lead, zinc, silver, cobalt and chemicals such as cotton phenol, dilaudid, chemotherapy, anti-hypertensive drugs, hormones, sedative drugs and narcotic drugs are taken as little as possible or not taken; long-term alcohol consumption Excessive alcohol consumption and smoking can cause impotence, abnormal ejaculatory function and even abnormal sperm quality resulting in infertility or abnormal pregnancy. Each patient should clearly understand that malnutrition can cause protein and vitamin and trace element deficiencies, so that sperm production and energy acquisition are affected, resulting in abnormal sperm quantity and quality, which can also cause male infertility. This is an important aspect of preventing male infertility, especially sexually transmitted diseases, which, once infected, not only obstruct the vas deferens, but also cause loss of gonadal function in severe cases. On the other hand, family entanglements and emotional discord caused by this factor can psychologically affect sexual function. 4. Treatment of varicose veins Varicose spermatozoa is another treatable aspect of male infertility, when men feel a downward feeling or earthworm-like bulge in the scrotum on the left or left and right sides, they should see a doctor and have surgery in time to avoid long-term varicose spermatozoa leading to testicular insufficiency. Other abnormalities in the urinary tract such as hematospermia and enlarged testicles need to be seen as soon as possible to avoid aggravation of the condition due to negligence, resulting in infertility or even more serious consequences. 5. Treatment of psychosexual abnormalities Psychosexual abnormalities can lead to sexual insufficiency, and sexual dysfunction can cause male infertility, so patients should be given the necessary examination and appropriate treatment as soon as possible. Chinese medicine attaches importance to the finishing of the conditioning, the diagnosis and treatment, the local lesions of male infertility in the systemic conditions, combined diseases, psychological changes and climate and other factors together, to take a variety of comprehensive treatment measures. The treatment of male infertility in our department gives full play to the advantages of Chinese medicine in the treatment of male infertility, and combines the advantages of Western medicine, such as antibiotic treatment of acute inflammation of the reproductive system, surgical treatment of vas deferens obstruction and assisted reproductive technology such as artificial insemination, according to the different causes of male infertility, focus on the rational use of different treatment methods to develop specific treatment plans to achieve better treatment results.
