Eight causes of decline in sperm quality of men

First, the sexual confusion and dirty
Sexual life can lead to confusion and dirty male reproductive tract infection. Reproductive tract infections caused by pathogens are Neisseria gonorrhoeae, Mycobacterium tuberculosis, viruses, mycoplasma, chlamydia, trichomonas, etc., of which the most common mycoplasma and chlamydia infections. First, reproductive tract infection affect sperm production and sperm transport, causing oligozoospermia caused by fertility decline. Reproductive tract infections can also cause changes in sperm motility, reproductive tract infections can inhibit the secretion of subsidiary gland, causing seminal fluid secretion, semen nutritional deficiencies, changing pH, semen components change, thus affecting the growth of the sperm environment in which the number of sperm vitality and serious down Erzhi infertility.

 
Second, tobacco and alcohol
Man on tobacco and alcohol is quite sensitive to the toxin, especially in germ cells more vulnerable. Studies show that nicotine in tobacco has reduced sex hormone secretion and the role of anti-sperm. Those who smoked 30 cigarettes, only 49% of sperm viability, the secretion of male hormone the body of smokers than non-smokers 16-47% less, so that a corresponding decrease sperm production. Long-term alcohol abuse will result in testicular germ cell damage, affecting sperm production.

 
Third, the thermal environment testicular damage
If long-term high-temperature, hot water bath, long-term wear tight pants, the function of regulating the temperature will produce scrotal disorders. Many men show fit body, long-term wear tight pants, everyone knows, the pants will be firmly affixed to the scrotum and testicles together, so that the skin cooling the scrotum not play, leading to an increased testis temperature is not conducive to sperm generated.

 
Also, wear tight pants also limit and prevent scrotum blood circulation, the formation of testicular blood stasis, leading to infertility. Testicles are the organs that produce sperm, testicular spermatogenic process requires the temperature must be at 35.5 ℃ to 36.5 ℃, normal body temperature between 1 and less than 1.5 ℃. Often with very hot water for bathing, especially the tub, sauna, so that the scrotum often in high temperature, will affect the testicular spermatogenic function.

 
Fourth, poor diet
Nutritional deficiencies such as vitamin A deficiency can lead to seminiferous epithelium is not long; vitamin B deficiency, can affect pituitary function, reduce fertility; vitamin C in preventing semen coagulation, sperm motility to maintain an important role in certain aspects; vitamin E deficiency can cause testicular damage; calcium, phosphorus deficiency can reduce fertility; lack of trace elements zinc and magnesium production and also on the vitality of the sperm have a greater impact. In addition, consumption of crude cottonseed oil, gossypol can damage the oil inside the spermatogenic cells, causing sterility; eat too much celery, can also cause infertility. A doctor in Thailand after 10 years of research prove the role of celery with contraception, acceptance testing of men eat 75 grams of cooked celery, ate 1-2 weeks, these men will be significantly reduced sperm count, from normal The number of sperm per milliliter of semen contains ten million to one hundred million was reduced to only 3,000 per milliliter, so little sperm count is difficult to make women pregnant.

 
Fifth, exposure to toxic substances
Many chemicals affect male reproductive function.
Such as organic pesticides: DDT, dieldrin, pine oil and other hydrocarbons. Organic phosphorus: parathion (1605), dichlorvos and so on. Others such as fungicides, acaricides, nitroso food additives. There are some metal elements such as copper, cadmium, lead, mercury and other items.

 
VI, drug damage
Modern medical studies have shown that many drugs can cause male infertility, mainly anticancer, anti-rheumatic drugs, antihypertensive drugs, hormone drugs, sedatives and narcotics (marijuana, heroin and other drugs.) Such as cyclophosphamide can spermatogenic dysfunction; methotrexate, cortisone class of agents, such as sulfasalazine given topiramate can cause reduced sperm count, sperm motility; cimetidine and other male hormone secretion through the inhibition of , and indirectly reduce sperm motility. Tripterygium and other long-term use also can reduce sperm count.

 
VII 性生活过频 or inappropriate
Although the testes to produce tens of millions to hundreds of millions of daily sperm, but after the first ejaculation, the sperm should be 5 to 7 days to mature and reach a sufficient quantity. If the number of excessive or uncontrolled sexual life, less sperm per shot, not easy to conceive naturally. In addition, interruption of sexual life, masturbation or sexual activity lasted longer each time, will lead to aseptic prostatitis, a direct impact on the nutritional content of semen and sperm motility, causing infertility.

 
VIII Excessive exposure to female substance
With the social development and environmental change, widespread and long-term exposure to low doses of more and more opportunities for female substance, such as artificial breeding of freshwater fish, poultry and other long-term consumption of such food, also contributed to the decline in male sperm count important reasons.
