Male sperm \"six\"

Because sperm has delicate, vulnerable to all kinds of \"enemy\", and therefore cut to be alert in their daily lives.

A fear of alcohol, tobacco

Smoking and alcohol abuse is the enemy of sperm. Some of the male body quite sensitive about the toxins in cigarette, nicotine in cigarettes can kill sperm. Australia a chemist said men once you kick the smoking, stress in the blood will increase. Hungary one medical doctor claims: contains the number of sperm in semen than smokers not less, and the number of abnormal sperm. Adult male 30 cigarettes a day, sperm survival rate of only $ 40%, and sperm deformity rate increases. Visible long term and excessive smoking is one of the important factors leading to infertility. Alcohol will not only result in reduced gonad function, sperm chromosomal abnormalities, causing fetal abnormalities or dysplasia. Youth should therefore develop away from tobacco and alcohol habits. Adults, even if they do not quit smoking wine, should also be careful not to excess.

Second fear \"starving\"

Nutrient supply sperm growth needs. Some men eating monotone, partial eclipse, finicky, does not like to eat animal food (such as meat, eggs, fish and dairy products), after a considerable period of time, can bring down the content of zinc in the body. Zinc was known as \"effects of conjugal harmony\"? child under number?? 0%~40%, or even lead to loss of fertility.

Three \"hot\"

Sperm growth process of low temperature, or sperm would die young. Maintaining such a physiological state, when the temperature is too high, expanding the radiation area, it will fold up in cold, to reduce the radiation area, so as to maintain the scrotal temperature lower than in the abdominal cavity. If men have loved hot shower hobby, fewer sperm, leading to infertility;

Four feared \"frequency\"

If excessive masturbation, early life, it can lead to impotence, can also cause ejaculation the sperm quantity less at a time.

Five feared \"medicine\" and \"Ray\"

Regular use of sedatives, antineoplastic drugs, chemical drugs in Maryland, furan, hormone drugs can cause sperm growth disorder, sperm chromosomal damage and fracture; a large number of radiation may also cause sperm chromosome aberrations. Therefore, the growth stages of males will try to avoid long term and excessive exposure to such harmful substances, not free to abuse drugs.

Six feared \"worry\"

If because of depressed mood, emotional long-term stability, can directly affect the nervous system and endocrine function, the spermatogenic function disorders, severe cases can lead to infertility after marriage.

Bad habits to reduce male \"fine\"

Journalists from CITIC xiangya reproductive and genetic specialist hospital was informed that, from 1999 to date, 1500 men donating sperm to the hospital, only 268 qualified, some 83% men do not cross the border. \"Man\'s physical decline to worry. \"A staff member in the hospital, told reporters.

It is understood that since 1999, which encourages people to public welfare donated sperm, predominantly students and 1500 sperm donor. Arguably, relatively young college students, energetic, and high quality of college students, and aristogenesis. But it is embarrassing, through layers of filtering, few candidates, more college students after the first sperm donation is testing for sperm is not qualified.

A staff member said, sperm banks need \"qualified sperm\" refers to meet the requirement of the Ministry of health, the density is 60 million. It is learnt that the donor semen stored in liquid nitrogen tanks, the constant temperature inside the tank in lingxia196℃. Defective sperm would be eliminated under low temperature conditions, is with the strongest sperm vitality of the recovery of \"fine\" good general. Semen must be kept for at least 6 months in the sperm bank, after again testing, confirm health after they have to provide to the artificial insemination of women needs to be done. But to provide the name of the identity of sperm, the hospital will be kept strictly confidential. To become a sperm donor for a qualified, first to three standard of semen and blood tests; blood passes, through physical examination; medical clearances in order to become a sperm donor. CITIC xiangya Hospital of reproductive and genetic data indicate that, to date, 1500 only 268 qualified of the sperm donor, approximately 83% sperm donor does not cross the border.

The experts said, bad living habits affecting men\'s sperm quality, these unhealthy habits including smoking excessive sexuality, alcohol abuse, excessive online and so on, causing poor sperm motility, sperm density is low, deaths and more than fine. It is understood, lack of sleep, poor sleep quality, no rule of life is also important cause of sperm in men declining physical fitness, is not eligible.

Reporters donors interviewed some of the litigants. Many people think that, as donor bone marrow and blood donation, donation is meaningful things, can be given to those who need help. Hunan University\'s Chen Hu (aliased) told reporters that the start he has also been on the donors hesitated, then think that this is a meaningful thing, still working up the courage to try. A public institution, who asked not to be named told reporters that he had in sperm bank donation fine. May be due to their smoking, drinking too much, though, the second test for the first time are forced through, has not qualified for the third time. He said: \"with my 3 friends and I also had to donors, finally and I did not have qualified, one of whom was eliminated for the first time out. That friend sometimes for a week in a row overnight on the Internet, is probably for this reason the effect him. ”

Ten factors affecting sperm quality

In the past 50 years, is the greatest debate about male reproductive health decline in semen quality on a global scale. Denmark scholar Dr niersi·shabake has a comprehensive analysis of the 1938-1990 years, nearly 15,000 people in 21 countries in the world of semen quality report, found that males has reduced the number of sperm in the 50 years more than 40%. Among them, semen volume reduced 20%, per milliliter of sperm density from 1940 reduced to 113 million per cent in 1990. After that, Europe, America and many Asian countries and regions have published a retrospective comparative data is supported by the vast majority of the decline in semen quality of conclusions.

Chinese scholars also have similar results. National population and family planning Commission of science and Technology Research Institute had published between 1981-1996, from Beijing, Shanghai, Tianjin, 39 counties, 256 copies of documents and, 11,726 sperm analysis data study found that male semen quality in China is falling at an annual rate of 1%, sperm count fell by more than 40%. And, the more industrialised areas, faster decline in sperm quality.

In recent years, in urology and Andrology outpatient clinical practice can see fall in sperm quality causes an increasing number of patients visiting because of male infertility. Due to reasons for the decline in sperm quality, some are congenital or acquired diseases, some some caused by human factors in life. Among them, has been in the study proved the following 10 factors, greatest effect on sperm quality of:

1, food packaging and cosmetics

Germany Research Association recently issued the press release said that the past decades, global reduction in male sperm counts may be related to a chemical called phthalate ester matter.

Phthalate esters are a class of chemicals can be softened. It is widely applied to the vinyl toy, food packaging, flooring, wallpaper, cleaning agents, lubricants, Nail Polish, hair spray, in hundreds of products such as SOAP and shampoo. Studies have shown that phthalate esters may interfere with the endocrine, to reduce sperm count in men, poor exercise capacity, deformity, serious can also lead to testicular cancer, was the cause of male reproductive problems \"blame\".

In cosmetics, Nail Polish had the highest content of phthalic acid esters. It will pass the women\'s respiratory system and skin inside the body, jeopardizing their future fertility of the male reproductive system.

Phthalic acid esters also enter the body through the plastic container packaging of food and water, recyclable milk such as inner coating of food cans, and bottles of mineral water. Studies have shown that higher the fat content in canned food food more vulnerable to pollution, such as pork, anchovies, sardines, etc. Fetal, infant and adolescent children on it are the most sensitive health is most vulnerable to abuse.

In order to reduce the harm of phthalic acid esters on the human body, usually to note it is best not to use styrofoam containers bubble instant noodles, do not use with PVC plastic containers in the microwave heating of food. Right thing to do is to put food on the heated in a heat-resistant glass or ceramic containers.

2, automobile tail gas

Automobile exhaust gas contains large amounts of harmful substances, such as sulfur dioxide, carbon dioxide, and so on. Human exposure to these substances for a long time, cumulative damage occurs, not only affects reproductive health also may increase the incidence of diseases such as cancer.

Most serious is that of automobile tail gas containing dioxin is a very strong environmental endocrine disrupting chemicals, can make men of morphological changes, reduced sperm count, testis spermatogenic capacity.

3, tobacco, wine

Smoking has long been a enemy of health, effects on sperm is equally clear. Foreign very early study showed that smokers compared to non-smokers, sperm quality of the main indicators are significantly reducing sperm deformity rate of rise, increased number of white cells in the semen. Nicotine in tobacco and polycyclic aromatic hydrocarbon compounds can cause testicular atrophy and sperm morphological change.

Alcohol on the human liver and testis in men have a direct impact. Study finds that testicular atrophy can occur in patients with chronic alcohol intoxication, causing semen quality. Therefore, the male must avoid frequent excessive drinking.

4, estrogen

Estrogen will have a significant impact on male reproductive system, including the effect of androgen levels, raise testicular tissue structural changes caused by testicular cancer, reducing the number of sperm in semen, causing Gynecomastia, lead to endocrine disorders. Men taking drugs containing estrogen and short-term will not significantly impact on the reproductive system, but long contact life articles containing estrogen, you will incur a larger reproductive health hazards. Such as when part of the male skin care free to use women\'s cosmetics. These specifically for women in the development of cosmetics, some containing a certain amount of estrogen, long-term use may cause damage to male reproductive health, causing sexual gland hypofunction.

5, trace elements

Associated with male fertility including trace elements such as zinc, selenium, copper, calcium and magnesium. Zinc is an important element within the reproductive system, zinc deficiency and second features affect adolescent male genital development, reducing the ability of sperm, weaken the body\'s immune function, men likely to suffer from prostatitis, epididymitis, and other infectious diseases. Lack of selenium will make peroxidase concentrations increase, causing damage to the testes of the male reproductive system and. Therefore, the male usually should eat foods containing higher zinc, selenium, such as milk, corn, black rice, black beans, and so on.

6, temperature

Damage to the testes produce high temperature, but under high temperature and this temperature exposure for many long, will have an impact on testis, now in academia are still disputed. In animal experiments, male

Placed under the 38.5 ° c after 55 minutes, their fertility will decline. In real life, men should avoid staying in high temperature environments for too long, such as sauna and hot baths.

7, drugs

Cancer, hormones, antibiotics and other drugs can damage the male Gonadal function, cause a decline in sperm count and quality, or by influencing the endocrine function of gonad, lead to sexual dysfunction. Drug effects on male fertility by type of drug, dosage, treatment, patient age and other factors. General drug dose, the greater, the longer the course, patient age, and the smaller, more serious damage to the reproductive function, the time required to restore fertility more.

At present, the spread of sexual health products in the community, some contain sex hormones or similar substances, may affect the normal testis spermatogenesis, unmarried not finishing choices should be cautious.

8, noise

With the development of modern, urban noise effects on health of the more prominent. Noise is pollution. In recent years, some experts raised the \"environmental hormone\" theory, that exists in the environment that affect the human body like a hormone endocrine function of chemical substances, noise is one of them. It causes the human endocrine disorder, causing semen and sperm abnormalities. Noise pollution for a long time can cause male infertility; women, causes abortion and fetal abnormalities.

9, radiation

Effects of radiation on human health has determined that there is clear. Large doses of radiation can cause changes in testicular tissue structure, increase sperm deformity rate, reduced sperm count, sperm density and other important indicators. However, small doses of radiation will cause infertility, there is no exact results. We daily use of electronic devices, such as mobile phones, computers will cause infertility, there is great controversy in the field. Therefore, the male usually should minimize exposure to the radiation source, but without excessive stress.

10, drugs

There are many people who take drugs in China, some drugs, such as cannabis, cocaine, have an impact on the quality of semen. Cannabis can make lower Androgen levels in the blood, declining sperm density, lead to Gynecomastia; cocaine would bring down the sperm density.

Major issues of sperm quality relationships with humans to survive and reproduce. For these factors, we should take on high alert, prompt attention and avoid the other hand, also to call on all forces to the whole society to improve the environment in which we live. Otherwise, it will be like United States scholar Xiao·keerboen in the book our stolen future, as stated in: infertility could become a widespread epidemic, man may become completely lost in the future fertility sth

Eat pumpkin child may improve sperm quality

United States scientists study found that eating pumpkin leaf and pumpkin, white onion, ginger, tomatoes and other food, coupled with the appropriate physical exercise and maintaining a healthy weight, such as not smoking and excessive drinking, will help to improve the quality of sperm in men.

Fertility experts point out that low sperm quality is one of the major causes of male infertility, but this state of affairs of some permanent, some are temporary in nature. United States magazine called the reproductive health, causing temporary poor sperm quality of a number of reasons, including sexually transmitted diseases, alcoholism, smoking, overworked underwear too tight, high temperature environment, work and emotional stress, insomnia, and so on. Patients can fully healthy lifestyle to improve the quality of sperm.

Nutritionists point out that many plants and healthy food helps to increase sperm count and improve the quality of sperm. Fresh green juice extracted from leaves of pumpkin with milk dilution volume, one cup per day could play a strong role in nourishing, helps to increase libido in men, improving sperm quality, restoring reproductive capacity.

There are several methods, will be the same amount of fresh white onions and garlic crushed, bubbles into the non-alcohol white wine in 10-14 days, three times a day, 100 ml each time, you can restore impaired reproductive tissue.

Lilac root at 30-40 get 200 grams of alcohol soaked in 14 days, after filtering with orange juice and take 500 ml and 1 l of pure natural honey mixed drink twice a day, each time you only need to drink, can help restore sperm quality.

Other herbs are useful for male fertility include mistletoe, fans of sub-er Sha, Chinese Milk vetch, grass, dodder and Korean ginseng. Study says, by zinc supplementation elements can not only promote the secretion of testosterone, you can increase sperm count, role of vitamin c also improve the quality of sperm. So, eat pumpkin is useful, because the pumpkin child is rich in zinc.

Sperm killers, blacklist list

In strength in most people\'s idea of sperm seems to closely and male sexual capacity, even though always confident on my bed capacity, once conceived by experienced difficult for the other half of embarrassment, inevitably ambitions also greatly reduced, large treasures lost!

Sperm is quite sensitive and fragile, from the daily life of various external or internal stimulation, are likely to reduce its vitality, and even kill its vitality.

Tadpoles active influence men living there are several factors:

1, the sperm will also temper Oh

Circumstances such as depression, spirit of good will have adverse effects on human endocrine, male production of testicular sperm function also be confusion, sperm count may be reduced, or even serious, the worries of infertility.

2, sperm are not high temperature high fever

\"Low temperature\" is the best breed of sperm space of high temperature on is a cruel test of survival for sperm. Therefore, the male likes to wear tight-fitting underwear, jeans or an unventilated hot bath immersion habits, even often work under high temperature environment, long down, watch out for the sperm from dying.

3, alcohol and tobacco ingredients poisoned sperm

Medical research indicates that nicotine in cigarettes ingredients can harm sperm, causing semen including fine reduction, will also increase of abnormal sperm content; in addition, alcohol causes a reproductive function weaker, caused chromosomal abnormalities, further onion? fetal malformations or dysplasia happens?? /P>

4, sperm need nutrition

Sperm is required for manufacturing and growth of the human body continue to supplement the basic nutrition, if males have the habit of the partial eclipse will cause uneven nutrient intake, let the hungry stomachs of sperm, can cause weakness, failure of sperm, even death, of course, on male sexual desire and sexual function will also have impeded.

5, medical drugs stimulate sperm

Drug sedative, hypnotic, anticancer drugs, in Maryland in the chemical, hormonal drugs impede sperm growth, so men should avoid long, much exposure to these hazardous substances. In addition, the radiation may also cause sperm chromosomal malformations, and should absolutely avoid abuse.

Why don\'t sperm \"fine\"

Sperm male reproductive cells. To reproductive a health smart baby, husband, first of all, there must be a high quality of the sperm.

According to authoritative statistics reports: in the past half century, male semen volume decreased from 3.4 ml to 2.5 ml of sperm density diluted by almost half, reduces per milliliter of sperm from 113 million to 66 million. Sperm quality may cause unpredictable dangers to the human qualities, to that end, people have conducted extensive research on the factors influencing quality of sperm, finding global environmental pollution is the main reason for the decline in sperm quality. Environmental factors affect sperm quality include:

1. metal has proven to have on the reproductive toxicity of metals such as mercury, lead and cadmium. Long-term exposure to these heavy metals can cause a decline in sperm counts, sperm density reduction, reduced sperm motility, and sperm deformity reduction in a row of fine increased.

2. with the development of agricultural pesticides and drugs, pesticide effects on sperm quality of more and more people pay attention to, such as Dichlorvos, Malathion, methylene blue, red, Indigo can affect sperm motion capacity, reduce the number of sperm, morphological changes.

3. organic material on the sperm toxicity of many organic substances, such as benzene, formaldehyde and harmful chemical substances such as food additives will impede the formation of sperm and vitality, even lead to testicular atrophy.

4. gas (exhaust) study found that the percentage of normal sperm frequently inhaling automobile exhaust sharply.

5. radiation germ cells is one of the most sensitive cells to radiation, excess radiation on sperm can produce adverse effects. , Nuclear radiation of electromagnetic waves, x-ray radiation is of human sperm killers, will enable germ cell abnormality, miscarriage in pregnant women and fetal development.

6. temperature testicular environment temperature if it exceeds 45 ° c for 2 hours, to the disadvantage of sperm, hot water bath, long wear tight pants, and so for a long time, you can build and viability of sperm is affected.

In addition, tobacco and liquor also damage sperm, daily smoking 30, sperm survival 49%, long-term or excessive intake, can lead to 70% Dysplasia of sperm and losing its vitality. One >>> eat pumpkin child may improve sperm quality symmetrical male sperm quality high

Sperm production is a complex process, environmental factors in any one of these links, can result in sperm quality. Only with good seed can bear great fruit.

Ten ways to improve the quality of sperm

Science Channel on September 16, it was Yahoo\'s Web site reported that nearly 3 million in the United Kingdom male sterility symptoms occur due to poor habits today, United Kingdom experts on fertility Winster and finally found the solution: sperm growth as long as 4 months time, as long as changing living habits at once, you can immediately improve sperm quality and quantity.

Participation in exercises. Studies have shown that male body obesity, will result in temperature increases at the inguinal, growth of damage sperm, resulting in infertility. Therefore, weight control in the context of standards can improve the quality of sperm. However, the exercise intensity to moderate, and vigorous exercise, such as Marathon and long-distance cycling still makes testicular temperature, damage sperm growth required a cool environment. Cycling also vulnerable testicle cystic arteries are in danger and, therefore, recommended cycling shorts to wear pads, and select shock features a good bike.

Small saunas, sauna. High temperature steam bath directly harm sperm, also inhibit sperm production.

Give up smoking. Data showed that 44% people think that smoking is the most important factor of decline in sperm counts, so smoking is imperative.

Moderate alcohol consumption. Large amounts of alcohol can lead to declining sperm quality, males should be strictly according to the daily 14-28 standard Cup (alcoholic 8-9 g), the female half of the recommended amount to perform.

Say no to anaesthetic. Narcotic drugs, the drug also has tremendous harms to sperm, and will continue for a long time.

Relaxed state of mind. Stress too large negative impact on the growth of sperm. So men should do to make things they relax, such as walking, bathing, and enjoy sex.

On the phone in his pocket. Phone in the trouser pocket, laptop on the lap, wearing tight pants can raise scrotum temperature, damage sperm, it should be on the phone in his pocket.

Eat more green vegetables. Green vegetables contain vitamin c, vitamin e, zinc, selenium, and so conducive to the development of sperm components. Rich in omega 3 fatty acids in nuts, fish, you should eat, conducive to sperm cell growth.

Often go to the clinic medical examinations. Pathogen infections are also important factors in male infertility, should constantly to the doctors there, accept chlamydia, prostate-related checks.

A self-test. Often with tools to test their semen.

Should not be ignored father\'s sperm health

All couples in the world, want to get a healthy and clever little baby. However, breed history of life is not so flat, there are ups and downs. Pregnancy is not a woman a man thing! Baby health sources in combination with a healthy sperm and eggs! So sperm cannot ignore the other half healthy!

· Age sth >>> don\'t miss the best men of child-bearing age you most want to know the eight pregnancy problems

Andrology expert, China Academy of traditional Chinese medicine in traditional Chinese medicine Andrology experience in urology Professor Jia Jinming Guang an men hospital said: \"the best should be child-bearing age is 24--30 years old. Although men had fully 18 years of age, women \"going to 14 days\" is menstruation, you can have a son, but this is not the most appropriate set of childbearing age. The other hand, men in the age of 40, physical fitness, has been gradually declining, at the same time and accumulate in the body by eating various pollution increased, therefore, in this case growing out of the next generation, chance prevalence will increase significantly. ”

· Tone sth >>> enhancing libido beginning with Kiss

\"Essence, Qi, spirit\" body \"Sambo\", three interrelated, complement each other. \"God\" is the external manifestation of human physical condition, the person\'s mental state, will directly affect children. Therefore, the view of traditional Chinese medicine to healthy growth, \"reducing interest\" be mind expansive, cheerful, learn to resolve a variety of unhealthy emotion, it is cultivating a very important and often overlooked.

· Movement sth >>> of the heroic cell: sperm team spirit

Intend to bear for some time, males should always maintain a certain degree of physical activity, work and rest. Flexible time based on individual physical condition developed, generally more than 3 times a week, more than half an hour at a time. In addition, lives to see sunlight, fresh air, this beneficial male endocrine coordination.

· Eating sth >>> preparation before pregnancy and reproductive health to sperm health diet recommendation 12

Professor Jia stressed that, in fact, in addition to the need to bogey estuary because of disease, what to do without favoritism, eat, this is the best diet recuperation. And the West \"to meat\" diet compared to Oriental especially the Chinese, \"mainly for cereals and pulses\" of the traditional diet is healthier. Note eat more peanuts, Sesame, eels, loach, pigeon, Oyster, Sparrow, leeks and other foods, which are rich in promoting the growth of zinc, and eat more liver, lean meat and other foods rich in amino acids. These food complemented Jing Yang, contributes to good sperm.

Abundant fish and meat rich food without much benefit to the human body, diseases such as prostatitis induced by eating much easier. Professor Jia, Western scientists have done an experiment, their anatomy has over 40 years of age of the deceased\'s prostate and found nearly all cancer cells. For poor fertility, Oligospermia patients, you can appropriate to eat lean meat and vegetables, lean meat and vegetables are rich in Vc, Va, Ve sperm are good.

· Defends the rule of sth >>> pregnant need before pregnancy \"carefully prepared\" small sperm quality before pregnancy battle

Fertility intention within the first six months of when you should do to stop smoking, drinking, or other bad living habits. In addition, for sex to \"let nature take its course\", no no, too even. In particular, not to pursue the so-called \"lasting, high quality\" sex and take the whip and tonics. For some patients with low sexual function does, should also be made under the guidance of experienced doctors of Chinese medicine medicine supplement.

Who was \"murdered\" the sperm?

Digital data show that nearly 50 years to gradually reduce the number of male sperm. United States lafu·duoerdi study of dazhou in the Robert Frost University found that United States men reduced the number of sperm in the past half century of almost one-third.

Sperm intermediate value of 90 million/ml in 1929, and in 1979 in the middle value of 60 million/ml, that is half a man\'s sperm than this number, half men below this number. Doherty Professor recently investigated 132 male college students found that human sperm counts not from 23% of/ml. …… Testicle can produce every day how much sperm

Easily hurt sperm

Judging from the biological characteristics of sperm, the sperm is a product of male germ cells and development of the Terminal. In the process of spermatogenesis, formation and deformation of, due to escape of cytoplasmic, cytoplasmic DNA repair enzymes in lost, made consequent loss of DNA damage and repair system functioning. So it\'s not somatic cells and egg cells can repair themselves as 90% of the primary genetic material damage. In the various cells in the human body, only sperm has such characteristics. In addition, compared with other types of cells, sperm more sensitive to toxic substances. Always the rapid fragmentation of spermatogenic cells, males from middle and late embryos to old age, will continually generate sperm. In fast in the spermatogenic process of, all kinds of hazards of harmful factors in the accumulation and accumulation increases after. With the deepening of the study and understanding of genes in recent years, more explicit, relative to the x chromosome, gene in the y chromosome carrying more prone to mutation.

Eight killer

Apart from genetic and part organic disease, closely related to the living habits of male infertility. Able to understand or overcome those bad habits in daily life, at least to reduce or avoid the occurrence of male infertility, then what factors can result in reduced male sperm and cause infertility?

First, sexual confusion and unclean.

Sexual confusion and unclean caused male reproductive tract infections. Cause genital gonococcal infection disease original, Mycobacterium tuberculosis, viruses, Mycoplasma, chlamydia and trichomoniasis, with Mycoplasma and chlamydia infection is most common. First of all, reproductive tract infections affecting sperm and sperm transport, cause oligospermia and caused reproductive capacity to decline. Reproductive tract infection can also cause changes in sperm motility, can suppress the subsidiary gonadotropin secretion of reproductive tract infections, caused by insufficient secretion of semen, semen nutritional deficiency, pH change, semen composition change, thus affecting the growth environment of sperm, sperm viability and by serious decline in the number of infertility. …… Experts reveal secret sex life and harmony

Second, the tobacco and alcohol abuse.

Men sensitive to toxins in the smoke, alcohol, in particular germ cells are more vulnerable to victimization. Research shows that of nicotine in tobacco have reduced effect of sex hormone secretion and kill sperm. Where 30 cigarettes a day, and sperm survival rate of only 49%, smokers amount of male hormone secretion in 16% per cent less than never smokers, so that the ability to lower the production of sperm. Long-term alcohol abuse can cause damage to testicular spermatogenic cells of affect sperm production. …… Prepare dozens when Dad needs to hide bad habits

Three, thermal environment on testicular damage.

Such as long-term heat, hot water bath, long-term wear tight pants, will regulate the temperature of the scrotum function disorders. Many men showed bodybuilding build, long wear tight pants, everyone knows, tight pants and testis in the scrotum will be firmly stuck together, hanging Qiang move し big ship na ⒒ δ Nai d skirt look bad pepper cherry? local temperature increase testes, inhibit sperm production. Addition to wear tight pants will limit and hinder parts of blood circulation in the scrotum, forming testicular blood stasis, leading to infertility. Organ of the testis is to produce sperm, testicular temperature must be requested in the spermatogenic process?? 5.5 to 36.5 ° c, 1 to 1.5 ° c lower than the normal body temperature. Often use very hot water bathing, especially bath, sauna, keep the scrotum in a high temperature State, affect testicular spermatogenesis.

Four, improper diet.

Nutrition lack, as vitamin-a lack, can led health fine epithelial does not long; vitamin b lack, can effect pituitary function, reduce reproductive force; vitamin c in prevent semen solidification, and keep sperm vitality aspects has must important role; vitamin e lack can caused testicular damage; calcium, and phosphorus lack can reduce reproductive ability; trace elements zinc and magnesium of lack also will on sperm of generated and the vitality produced larger effect. In addition, consumption of crude cottonseed oil, then gossypol can damage of spermatogenic cells, causing infertility; excessive consumption of celery, can also cause infertility. Thailand a doctor after 10 years of research, proof of celery have contraceptive effects, men eat 75 g cooked celery tested, after you eat 1 to 2 weeks in a row, these men will significantly reduce the number of sperm, from tens of millions of to 100 million per millilitre of semen containing sperm normally reduced to only 3,000 per ml, conceived by the sperm count is difficult to make women less so. …… 12 to sperm health diet recommendations

Five, exposure to toxic substances.

Many chemicals may affect male reproductive function. Organic insecticide: DDT, dieldrin, 666, such as pine oil hydrocarbons. Organophosphate: parathion (1605), Dichlorvos, and so on. Other fungicides, acaricides, nitroso-food additives, and so on. There are some metals such as copper, cadmium, lead and mercury.

Six, drug damages.

Modern medical research has proven that many drugs can cause male infertility, the main anti-cancer drug, antirheumatic drug, antihypertensive drugs, hormone drugs, sedatives and anesthetics (

Cannabis, heroin and other drugs). Such as cyclophosphamide may make spermatogenic function; methotrexate, adreson class preparation, Liu sulfonic effects such as decrease in sperm motility induced by nitrogen, sperm reduces; cimetidine by inhibiting testosterone secretion, indirectly reduced sperm motility. Long-term use can also decrease the sperm count of tripterygium wilfordii. …… Lycopene in treating male infertility

Seven, sexual life too frequent or inappropriate.

Although the testes can produce tens of millions of daily to hundreds of millions of sperm, but once after ejaculation, sperm after 5-7 days to mature and achieve sufficient quantities. If the number of sex too much or no restraint, less injection of sperm at a time, is not easy to conceive naturally. In addition, sexual life interrupted, masturbation or sex life of long duration, will lead to sterile prostatitis, directly affect the nutritional composition of semen and sperm motility, causing infertility. …… Relationship between frequency of sexual intercourse and eugenics

Eight, excessive contact with female substances.

With the development of social and environmental change, broad and long term exposure to low dose females material more and more, such as artificial rearing of freshwater fish, poultry, long-term consumption of these foods, as well as important reasons for the decline in the number of male sperm.
