Daily life health care is very important to improve male fertility, the following are the things that men in their reproductive years should pay attention to: 1, quit smoking. Smoking can cause a reduction in sperm count, sperm cell membrane and DNA damage. Long-term smoking or inhalation of second-hand smoke can easily cause male infertility and impotence, female miscarriage and fetal malformation. Some studies have shown that quitting smoking can really improve semen quality. 2, quit drinking. Excessive alcohol consumption can affect sperm production and development and maturation, leading to a decrease in sperm fertilization, and may also cause low libido, impotence, premature ejaculation and other sexual dysfunctions, which can easily lead to male infertility. 3, avoid sedentary. Office sedentary or cycling, driving and other behaviors will make men sit too long, will cause the male reproductive organs (testicles, epididymis, prostate and seminal vesicle glands) blood circulation is not smooth, so that men are prone to chronic prostatitis and epididymitis; will also cause the testicular temperature will rise, and then directly damage the testicular spermatogenesis, which will lead to a decline in the quality of spermatozoa. It is recommended that sedentary men get up and move around at least every half hour. 4, avoid staying up late. Because the production of spermatozoa is mainly at night, staying up late will lead to spermatogenic dysfunction, resulting in a decrease in sperm count, poorer vitality, and higher deformity rate. Frequently stay up late will also lead to male reproductive endocrine disorders and decreased immunity, resulting in sexual dysfunction, decreased libido, easy to suffer from chronic prostatitis and epididymitis. It is recommended that men in their reproductive years should have a regular work and rest schedule and avoid staying up late to ensure that the 8 hours of sleep from 11:00 p.m. to 7:00 a.m.. 5. Avoid high temperatures. Testicular spermatozoa generation requires the right temperature than the body temperature is also lower than 1 ~ 2 degrees (35.6 ℃ ~ 36 ℃, the temperature exceeds 37 ℃ will cause damage to spermatozoa), high temperatures will seriously damage the testicular spermatogenic function. Men in their reproductive years should try to avoid hot springs, saunas, wearing tight underwear and thick pants, laptop computers directly on their knees and other behaviors, and avoid working in kitchens, boiler rooms and other high-temperature environments. 6, avoid contact with toxic chemicals and radiation. x-rays, marble release of excessive rays, chemotherapy drugs, pesticides, insecticides, paints, formaldehyde, benzene, some food additives and preservatives, some of the food packaging plastics, heavy metals (eg, aluminum, lead, cadmium, mercury, etc.), welding, printing and plastics manufacturing, and other work environments will damage spermatogenesis, which can easily lead to sperm reduction and deformity, and should be avoided as much as possible. The work environment of lead, cadmium, mercury, etc., welding, printing and plastic manufacturing can damage the spermatogenic function and easily cause sperm reduction and malformation, and should be avoided. 7, avoid excessive contact with electronic products. Cell phones, computers, televisions, microwave ovens, air conditioners and hairdryers and other equipment will produce electromagnetic radiation, sperm are very sensitive to electromagnetic radiation, so too much exposure to electromagnetic radiation will cause sperm count and vitality decline. 8, avoid emotional tension and anxiety. Mental stress will affect the spermatogenic function through the neuroendocrine system, resulting in a decline in sperm count and vitality. Men in their reproductive years should learn to self-regulate their emotions and maintain a comfortable mood, which is conducive to eugenics. 9, reasonable diet. The production and development of spermatozoa require adequate intake of protein, vitamins and trace elements. Spicy food may induce prostatitis and other diseases, leading to oligospermia or poor semen liquefaction. Men in their reproductive years should eat more food rich in protein, zinc, selenium and other trace elements and vitamins, such as sea cucumbers, oysters, eggs, milk, corn, walnuts, as well as apples and tomatoes and other fresh fruits and vegetables, and try to avoid eating spicy food. 10, moderate physical exercise. Men in their reproductive years should carry out moderate physical exercise to enhance physical fitness. But pay attention to grasp the amount of exercise, because too intense exercise, will make the male body hormone secretion disorders, affect the sperm production. 11, adequate and regular sex life, this is the most important one. Trying to get pregnant naturally couples should work closely together, as long as the woman is not in the menstrual period, insist on having sex every 3 to 5 days, the woman is best to monitor ovulation, and increase the number of times of sexual intercourse when the woman is ovulating, in order to increase the chance of conception.
