A drop in the quality of semen, led directly to the human fertilisation ability. At present, infertility rates abortion rate, reproductive system neoplasms and neonatal hypospadias birth defects such as increased incidence, precocious puberty, men and women change wait for the incidence of abnormal sexual development also shows ascendant trend, it is considered and semen quality down there is some relation.
Human sperm is vulnerable, and difficult to repair the character, make many factors are the common sperm "killer" :
First, the pollution of the environment
There is a certain type of "environmental hormone" also known as "kind of hormone," "endocrine disturbance material", exist in the environment with similar characteristics of estrogen chemical. They enter the body will be in the role of the DuoGe sperm development link, lead to a man's sperm malformations, quantity and quality fell, the women pregnant rate reduced greatly, even completely lose the ability of giving birth.
Contains a variety of environmental hormone pollutants, mainly exists in pesticide, fertilizer, pesticide, detergent, plastic products, plasticizer, asbestos, chemicals, car tail gas, waste incineration produced gas, some heavy metals and cosmetics. People often contact in the 200 DuoZhong compounds, and more than 60% of sperm have to irreversible toxicity, another 20 DuoZhong occupational poison could hurt sperm.
Due to the increasingly serious environmental pollution, the number of men's sperm in the past 50 years almost to reduce by half. The environment pollution caused by acute or chronic poisoning, all can make in the testicles of the enzyme activity reduced, the influence of birth process, sperm deformity ratio increased, its vitality, penetration and the pregnant rate on the decline.
Engaged in work, high temperature radioactive assignments, and long time contact with paint, coating and mercury, lead, phosphor and toxic substances and lack of protective measures work personnel, it is infertility high-risk groups. By sperm quality and the quantity of decline and affect fertility proportion at about 40%.
Can say, the pollution of environment is sperm first killer. It more of a threat to humans in that it has the latent, durability and not NiZhuanXing, in the short term (a few years, ten years) inside people be aware of not easily it harm.
Second, smoking, alcohol
The nicotine in cigarettes can kill sperm, cause spermatozoon growth is bad, the deformity, defective sperm increased the proportion of, can even make a variation of sperm chromosomes, cause genetic changes. Excessive smoking can also cause semen thiocyanate content increased, thus inhibiting sperm activity. Survey: YanLing more long, the greater the march, then the sperm count is less, the sperm deformity of the higher rate, the lower sperm activity ability. If you are going to want a healthy baby, best plan before conception of 3 months to half a year to quit smoking of bad habits.
Alcohol on reproductive cells have strong poison effect, can damage the sperm and influence the development of embryos. Long-term a large number of drinking can cause male fertility decline. Now proof, alcohol can make testosterone synthesis to slow, and affect the normal metabolism of testosterone, cause ShengShiXian function is lower, and the generation of affect sperm and semen quality. Western countries some people like drinking, often on Sunday and get drunk, the night after her pregnancy was a known as "Sunday baby". The baby often constitution is very weak, dysplasia, even deformity or dementia. Therefore, the man before conception plan two to three months had better drink little or even no drink, in order to ensure that the sperm quality. Man excessive drinking can also cause impotence or temporary sexual incompetence.
Third, diet to be not moved
Sperm production need nutrient supply, malnutrition or not balanced are directly affect sperm formation. Nutritional components of the cholesterol, arginine, zinc and fertility of the most close relations. Cholesterol is a synthetic sex hormones important raw materials; L-arginine is a necessary formation for the sperm component; Zinc is human body important trace elements, the sperm of the content of zinc than in the plasma to nearly one hundred times as high. Zinc directly involved in the solution of sugar in sperm and oxidation process, maintain the integrity of the sperm cell membranes and permeability, to maintain the vitality of sperm. The lack of zinc can lead to testicular atrophy, sperm population decline, the function decline, serious or even lose fertility.
Many male friends are very like coffee, cola drinks, actually this kind of beverage is kill fine, so male friends want to drink less this kind of drink. In addition to kill fine food and celery, roast beef and mutton, etc.
The following food to improve sperm quality: carrots, garlic, kelp, mushroom, green beans, eel, loach, squid, ribbon fish, eels, sea cucumber, cuttlefish, yam, ginkgo, bean curd, put.
Fourth, the temperature too high
Sperm production process need lower temperature. Testicular temperature lower than in temperature of the scrotum to success in the produce sperm. As in patients of cryptorchidism was not in the testicles scrotum, but in the long run is high in temperature of the scrotum 2 ~ 3 degrees Celsius in other parts of the body, sperm cells born an irreversible damage, can't produce sperm. Therefore, any make genital parts of high temperature clothing, life habits and the environment, that makes it possible for the decrease in the number of sperm and impact becomes pregnant, and even cause infertility. Such as engaged in high temperature operation, is used to use the water of overheat bath, often wash sauna, often wear the jeans fit curve, will directly to male infertility.
5 and certain drugs
Anti-tumor medicine cyclophosphamide, vincristine, treat gout autumn of narcissus, alkali treatment for rheumatoid arthritis tripterygium wilfordii, etc. Can be cause sperm growth disorder. Single amine oxidase inhibitors, antihypertensive drug, aspirin, health thiazole of ketone, gossypol etc all can affect sperm formation. In the food preservatives, hydrogen peroxide solution to sperm has certain toxic effect. Antiepileptic p: dilantin inhibit the pituitary gland secretion of gonadotropins role, indirectly affect sperm production. Testosterone can restrain the function of the hypothalamus and inhibit born fine process.
Sixth, ray
Born in sperm cells radiation very sensitive, if by the direct illuminate radiation, can make give birth to gradually reduce the number of sperm cells. But this kind of the extent of the damage and the rays of strength, illuminate the length of time it has relationships: ray strength was weaker, time is short of damage is lighter, damage may be temporary, also can restore fertility; And a strong ray strength or long time may cause irreversible infertility. Long-term exposure to radiation, such as a technician, nuclear radiation workers, and so on, can be influenced by the role of the radiation in sperm production and inhibition, and can cause sperm chromosome aberration.
The seventh, in low spirits
Working pressure, the body often in fatigue, life is not rule, bad state of mind, stress and anxiety emotions all can directly affect the nervous system and endocrine function, make testicular pure function occur disorder was born.
