1. Sexual life is chaotic and unclean
Sexual life is chaotic and unclear causes male reproductive tract infections.The pathogens that cause reproductive tract infections are gonococcus, tuberculosis, virus, mycoplasma, chlamydia, trichomoniasis, etc. Among them, mycoplasma and chlamydia infection are the most common.Reproductive tract infection first affects the generation of sperm and the transportation of sperm, resulting in young sperm and causing reproductive ability.Genital tract infection can also cause sperm vitality changes. Reproductive tract infection can inhibit the secretion of intrinsic glands, cause insufficient semen secretion, lack of semen nutrition, changes in acid and alkali, and changes in semen composition, which affects the growth environment of the sperm and causes the vitality and number of sperm to be serious.Decreased infertility.
Second, smoking and alcoholism
Men are very sensitive to toxins in smoke and alcohol, especially for reproductive cells are more likely to be harmed.According to research, nicotine in tobacco leaves has the effect of lowering sex hormone secretion and killing sperm.Anyone who sucks 30 cigarettes a day, sperm survival rate is only 49%, and the male hormone secretion in the body is 16%to 47%less secretion than those who do not smoke, thereby reducing the ability of sperm to produce sperm.Long -term alcoholism can cause damage to the raw cells of the testicles and affect sperm production.
Third, the warm environment damage the testicles
If long -term high temperature operation, hot water bath, and long -term tight pants, the function of the scrotum adjustment temperature will cause obstacles.In order to show a bodybuilding figure, many men wear tight pants for a long time.produce.
In addition, wearing tight pants will also limit the blood circulation and hinder the scrotal area, forming testicular blood stasis, leading to infertility.Testicles are organs that produce sperm. The temperature of the testicles requires that the temperature must be from 35.5 ° C to 36.5 ° C during the process of sperm, which is 1 to 1.5 ° C than the normal body temperature.I often use very hot baths, especially pots and sauna, so that the scrotum is often in high temperature, which will affect the sperm function of the testicular.
Four, improper diet
Nutritional deficiency, such as vitamin A deficiency, can lead to sperm and epithelium; vitamin B deficiency can affect pituitary function and reduce fertility; vitamin C has a certain role in preventing semen solidification and maintaining sperm vitality; vitamin E deficiency can cause can cause can cause can cause can cause can cause can cause can cause can cause can cause can cause can cause can cause causeTeste damage; calcium and phosphorus deficiency can reduce fertility; the lack of trace element zinc and magnesium will also have a great impact on the production and vitality of sperm.
In addition, consumption of crude cottonseed oil, glycol in oil can destroy sophisticated cells and cause infertility; eating too much celery can also cause infertility.After 10 years of research in Thailand, a doctor proves that celery has contraceptive effects. Men who receives experiments eat 75 grams of celery every day. After eating for 1 to 2 weeks in a row, the number of sperm of these men will be significantly reduced, that is, from normal, that is, from normal, that is, from normal, that is, from normal, that is, from normal, that is, from normal, that is, from normal, that is, from normal, that is, from normal, that is, from normal, that is, from normal, that is, from normal, that is, from normal, that is, from the normal, that is, from normal, from normal,Tens of millions of sperm per ml sperm contains tens of millions of sperm to only 3,000 per milliliter. Such a small number of sperm is difficult to make women conceive.
Five, contact with toxic substances
Many chemicals can affect male reproductive function.
Such as organic pesticides: DDT, Di Shi, pine oil, etc.Organic phosphorus: Sulfur (1605), dichlorvos, etc.Others such as fungal agents, mate -killer, nitrolin food additives, etc.There are also some items containing metal elements such as copper, cadmium, lead, mercury, etc.
6. Drug damage
Modern medical research has proved that many drugs can cause male infertility, mainly anti -tumor drugs, anti -wind and damp drugs, anti -hypertrophic drugs, hormone drugs, sedatives and anesthesia (cannabis, heroin and other drugs).Such as cyclopensicide can cause testicular sperm functional disorders; methotrexate, pine preparations, willow nitrogenin, etc. can reduce sperm and reduce sperm vitality; Simiidine, etc., Indirectly reduce sperm vitality.Long -term use of Ray Gongjo can also reduce the number of sperm.
Seven, sexual life is frequent or improper
Although testicles can produce tens of millions to hundreds of millions of sperm per day, after ejaculation, sperm can be mature and reached enough after 5 to 7 days.If there are too many sexual life or no control, the amount of sperm shot at each time is not easy to conceive.In addition, sexual life is interrupted, masturbation or duration of each sexual life can cause sterile nature, which directly affects the nutritional components and sperm vitality of semen, causing infertility.
8. Excessive contact with female material
With the development of society and the changes in various environments, there are more and more opportunities for people to expose low -dose female substances for a long time, such as artificially raised freshwater fish and poultry.Important reason.
