Improper diet
A rich diet can provide sperm -generating various protein, calcium, zinc, selenium, selenium, phosphorus, magnesium, VITA and VITE and other nutrients.If partial eclipse, it is possible to lack these necessary substances, resulting in a reduction in the number and quality of sperm.Long -term deficiency zinc/selenium can lead to reduced fertility, decreased sperm, increased malformations, and increased risk of deformity in embryos.A zinc -containing foods include walnut kernels, pork liver, soybeans, greens, dried kelp, peanut rice, shrimp skin, cuttlefish, etc.Studies have confirmed that proper zinc supplement selenium can improve sperm vitality, improve sperm form, and increase fertilization.
Excessive exhaustion, long -distance cycling
The perineal and scrotum are squeezed for a long time, which affects the secretion of prostate and seminal vesicles on the one hand; on the other hand, the testicular ischemia is in ischemia for a long time and even slightly trauma.These can affect the quality of semen.
Bad mental state
Excessive psychological pressure, long -term being too nervous, depression, anxiety, pessimistic sorrow, etc. can all lead to decreased semen quality, dysfunction of sperm function, and decrease in pregnancy.
Sedent
Seating for a long time is currently the most common bad living habits.Sitting for more than 8 hours a day, for more than one year, the quality of semen has decreased significantly.For those who last for more than three years, the quality of semen is about 46%.At the same time, research also found that changing lifestyle habits, abandoning sedentary, increasing exercise, and adhering to exercise (fast walking or slow walking, running, swimming, ball movement, etc.) is beneficial to improve sperm quality.
Smoke
Cigarette smoke contains mutagencies that cause sperm to cause mutations, which can not only cause damage to the genetic material of the body cells, but also affect the maturity and proliferation of germ cells through blood & mdash; test barrier, leading to increased sperm DNA chain, sperm deformityThe rate increases.
alcoholism
Ethanol has a significant damage effect on sperm density, vitality, activity, morphology and fertilization.The degree of damage is closely related to the age, drinking amount and duration of drinking.Long -term drinking can lead to alcohol poisoning, causing testicular atrophy, decreased sexual desire, increased sperm malformation rate, total and density decrease.The sperm survival rate of poison in chronic alcohol is less than 80%, and the sperm malformation rate can be as high as 83%.The harm caused by drinking before the age of 18 is obviously better than adults who drink alcohol after the age of 18.
Ethanol may indirectly affect the sperm by affecting the synthesis of sex hormones, or directly damage the testicular sperm tubular pipes of the sperm, which causes degenerative changes in gonads, reduced testicular sperm function, and even atrophic.Ethanol also has a direct effect on sperm, which can cause sperm morphology to change the sperm morphology, including the head falling, the expansion of the middle of the neck, the curl of the tail, and the sperm condensed.The dysfunction of the hypothalamus-pituitary-testicular gland axis caused by drinking can cause testicular atrophy, sperm startup, differentiation, development and its quantity, form and function abnormalities.
Improper sexual life
The sexual intercourse of appropriate frequency is not only conducive to the physiological health and psychological balance of both men and women, but also improves the quality of semen and increases the chance of conception.However, sexual intercourse is frequent, which will reduce the density and number of sperm and affect the surgery of the spouse, not like some friends who mistakenly believe that "diligence can be harvested";Different rooms or non -ejaculation, sperm vitality and fertilization ability will also decrease, not as short as abstinence, the better the sperm quality.WHO recommends that the quality of semen with abstinence for 2-7 days can best reflect the real fertility of men at this stage.
