Children are the crystallization and extension of love, as well as the hope of career and family, the future of the motherland. Therefore, the inability to have children can cast a shadow on the life of the couple, the harmony of the family, and even bring a disastrous blow, carrying a heavy burden of thought. And this blow is especially bad for the female partner. In China’s feudal society, no queen is listed as the first unfilial, the crime is big. And whether you want to, should not, this crime always fall on the head of women, in the technological progress, social development today, we should “vindicate” for women, childbirth and child rearing is a joint effort of both spouses to complete, so the cause of fertility disorders should also be in both spouses to find the cause, rather than blindly conclude which party is the problem. Some men are macho, some are ignorant, and some are prejudiced by the world. It is important to point out that we should clarify what infertility and infertility are. Any couple who has lived together for more than one year without using contraception and cannot conceive is called infertility. It is usually called female infertility when it is caused by the female partner and male infertility when it is caused by the male partner. Statistics show that about 40% to 50% of infertile couples are caused by the female partner, 25% to 40% by the male partner, 15% to 20% by both partners, and 10 to 15% by unknown causes. If the female partner is determined to be normal in fertility and pregnancy by gynecological examinations, and the male partner causes infertility, it is called male infertility. Of course, we believe that for couples who have not undergone systematic examination, we should not draw premature conclusions about infertility to avoid unnecessary psychological burdens. What are the common causes of male infertility? A normal fertile man must have the following conditions: (1) normal reproductive organs and functions; (2) normal sexual functions; and (3) the absence of antibodies in the male body that cause sperm to agglutinate and brake. One of the conditions for conception is that the man can provide a sufficient number of healthy sperm and feed them into the appropriate part of the female reproductive organs, and any abnormality in this process can cause infertility. Specifically, there are many causes of male infertility, such as classification from etiology: ① congenital developmental abnormalities; ② hereditary disease infertility; ③ endocrine disease infertility; ④ germ line infection infertility; ⑤ varicocele infertility; ⑥ sexual dysfunction infertility; ⑦ physical and chemical factors causing infertility; ⑧ psychosomatic infertility. Classification from semen characteristics: ① azoospermia; ② oligospermia; ③ low sperm motility and dead sperm; ④ semen non-liquefaction; ⑤ excessive sperm malformation; ⑥ abnormal semen volume; ⑦ abnormal semen acidity, etc. Classification according to the nature of the lesion: organic and functional infertility. Organic infertility refers to infertility caused by pathological changes in the reproductive organs and their adjacent tissues; functional infertility refers to sexual dysfunction only after examination without finding pathological changes. Classification according to prognosis: absolute infertility (such as congenital developmental abnormalities, azoospermia, etc.) and relative infertility. The former is impossible to have children even with treatment, while the latter has the possibility of recovering fertility after treatment. Therefore, if a couple is still infertile after one year of marriage without contraception, they should go to a hospital for a detailed and systematic examination to clarify the cause and treat the symptoms as early as possible. Since semen abnormalities are the main cause of male infertility. Therefore, the treatment of male infertility should mainly focus on improving semen quality. Of course, it should be noted that male infertility patients with semen abnormalities should undergo relevant systematic examinations to find out the cause of the semen abnormality, and while taking drugs to improve the semen abnormality, they should also treat and eliminate the cause of the problem, which is the only way to treat the root cause and remove the root cause. In addition, patients should not buy their own so-called kidney tonics, liquor or prescriptions to take with little knowledge of this area, and they should not believe in the elixir of a charlatan doctor, otherwise it will not only cost a lot of money, but also bring a lot of harm. For most patients with semen abnormalities, as long as the diagnosis is correct, it is possible to correct and cure through more systematic treatment. So male infertility need not be overly anxious (this psychological state has a very negative effect on fertility). Under the guidance of a doctor, a systematic examination should be carried out to clarify the cause of the disease and treat it as early as possible. In daily life, one should try not to drink alcohol, which according to research has the effect of killing sperm and causing sperm malformation, and should also avoid smoking and spicy stimulating food. In addition, should also avoid contact with radioactive and harmful chemicals, can not eat cottonseed oil, cottonseed oil in the cotton phenol also has a sperm-killing effect, some chemical synthetic drugs should also be taken with caution, to be taken under the guidance of a doctor, do not wear tight clothing and pants and long hot tub bath, so as not to cause the local testicular temperature is too high, affecting the survival of sperm.
