The year of the monkey is getting closer and closer, how to have a healthy “monkey baby” is a problem in front of our fathers-to-be, how scientific, convenient and fast to do this, and listen to me slowly. I, the male side of the pre-conception test 1, semen examination is the most basic and important way to determine the fertility of men, mainly including the number of sperm, vitality, morphology, sperm acrosome function, sperm nuclear DNA fragmentation and infection indicators. It is best to abstain from sex (no intercourse or ejaculation such as masturbation) for 3~7 days before coming to the hospital for semen examination, because abstinence time too short or too long can cause inaccurate semen examination results. 2. Sexual function assessment. As men age, many men experience sexual dysfunction such as decreased libido, penile erectile dysfunction, premature ejaculation or ejaculation difficulties, which can cause disharmony in the couple’s sexual life, affect the couple’s relationship, and can cause infertility in serious cases. To determine whether the male sexual function is normal, mainly rely on the male doctor to ask the performance of the male partner during sex, if necessary, you can do sex hormone and other tests. At present, most of the sexual dysfunction, through reasonable treatment can be improved or cured. 3, sexually transmitted disease examination, mainly including syphilis, AIDS, herpes virus and chlamydia examination. Men who have prostitutes and other unclean sexual behavior before giving birth, it is best to go to the regular public hospital’s Department of Venereal Diseases to check. It is important to treat STDs when they are found so as not to affect the woman’s pregnancy and the health of the next generation. Peripheral blood karyotype of both husband and wife. The karyotype is a basic indicator of whether the human genetic material is normal. Parents with karyotype abnormalities have a much higher probability of having offspring with serious chromosomal abnormalities than normal people, and are especially prone to fetal abnormalities and miscarriages. Therefore, it is better to have a checkup, and the test results are valid for life. Even if the test reveals karyotype abnormalities, it is not a terrible thing because the third generation IVF technology can help parents with karyotype abnormalities to choose to have healthy offspring with normal karyotype. Second, adjust habits and diet, and stay away from harmful environments Bad habits such as staying up late, smoking, and drinking can cause a decrease in male fertility and increase the risk of fetal malformation and miscarriage. Because the cycle of sperm production is about 3 months, so the father-to-be planning to have children, it is best to start adjusting habits, scientific and reasonable diet and away from the harmful environment 3 to 6 months in advance, commonly known as “closed mountain forestry”. 1, do not stay up late. Staying up late and not getting enough sleep has become the number one killer of male reproductive health. The company’s main goal is to provide a comprehensive range of products and services to the public. Staying up late often also leads to male reproductive endocrine disorders and decreased immunity, causing low libido, impotence, premature ejaculation and other sexual dysfunctions, prone to chronic prostatitis and epididymitis. Men should avoid staying up late, go to bed before 11 p.m., to ensure that 11 p.m. to 7 a.m. this 8 hours of effective sleep time. 2. Quit smoking. Smoking can cause a decrease in the number of sperm, sperm cell membranes and DNA damage, long-term smoking or inhalation of second-hand smoke can easily cause male infertility and impotence, female miscarriage and fetal abnormalities. Some studies have shown that quitting smoking can improve semen quality. 3. Drink less alcohol. Excessive alcohol consumption can affect the production and development and maturation of sperm, leading to a decrease in sperm fertilization ability, and may also cause low libido, impotence, premature ejaculation and other sexual dysfunction, which can easily cause male infertility. It is recommended to drink less alcohol, especially not highly white wine and foreign wine. 4, avoid sedentary. The act of sitting or cycling, driving will make men sit too long, which will cause poor blood circulation in the male reproductive organs (testes, epididymis, prostate and seminal vesicle glands), making men susceptible to chronic prostatitis and epididymitis; it will also cause the testicular temperature to rise, directly damaging the sperm function of the testes, which will lead to a decline in sperm quality. It is recommended that sedentary men stand up for a while at least every half hour. 5, avoid high temperature. The appropriate temperature required for sperm production in the testicles is 1 to 2 degrees lower than the body temperature (35.6°C to 36°C, the temperature exceeds 37°C will cause damage to the sperm), high temperature can seriously damage the testicular sperm function. Fertile men should try to avoid wearing tight underwear and thick pants, soaking in hot springs, steaming saunas, placing laptops directly on their knees and other behaviors, and avoid working in kitchens, boiler rooms and other high-temperature environments. 6, moderate physical exercise and sports. Exercise for half an hour to an hour a day, such as jogging or walking, is helpful to improve sexual function and fertility. But do not be too tired, because too intense exercise, will lead to endocrine disruption and immune system decline. 7, reasonable diet. The production and development of sperm requires the intake of sufficient protein, vitamins and trace elements. Genetically modified foods may cause infertility, and spicy foods tend to induce prostatitis and other diseases. Therefore, men should eat more eggs, milk, beef, mutton, corn, walnuts, oysters, apples and tomatoes and other fresh fruits and vegetables, and try to avoid spicy foods and genetically modified foods. 8, avoid contact with toxic chemicals and radiation. x-ray, marble release of excessive rays, chemotherapy drugs, pesticides, pesticides, paints, formaldehyde, benzene, heavy metals (such as aluminum, lead, cadmium, mercury, etc.), welding, printing and dyeing and plastic manufacturing and other work environments may cause a decrease in the number and vitality of sperm, malformation and DNA fragmentation rate, seriously impairing male fertility, should try to avoid contact. 9, avoid excessive exposure to electromagnetic radiation. Sperm is sensitive to electromagnetic radiation, too much exposure to electromagnetic radiation will cause a decline in sperm quality and sperm DNA damage, which may cause male infertility and female miscarriage. It is advisable not to put cell phones and computers with wireless Internet access on too close to the scrotum, and not to stay too long near WiFi transmitters, electromagnetic wave towers, high-voltage substations, radar stations and other equipment with strong electromagnetic radiation. There is also the north is now in winter, many people like to use electric mattresses for heating, this can be warmed up again before not sleeping, but in sleep is not allowed, because it will produce electronic waves on the testicles to a great impact. 10, avoid emotional tension and anxiety. Too much mental stress will affect sperm production and sexual function through the neuroendocrine system, causing a decline in sperm quality and sexual dysfunction. Men should learn to reduce their stress and regulate their emotions, to keep their mood relaxed, which is conducive to improving sexual function and semen quality. Third, adequate and regular sex life Adequate and regular sex life is not only good for men to maintain good sexual function and improve the quality of sperm, but also to improve the success rate of natural pregnancy. When couples try to get pregnant, as long as the woman is not in her menstrual period, it is best to insist on having sex once every 3 to 4 days to help improve the success rate of pregnancy. Women are most likely to get pregnant when they are ovulating, and they can have intercourse once every two days during ovulation to increase their chances of getting pregnant. When a woman has normal menstruation, the “possible ovulation date” is 14 days backward from the first day of her next menstrual period, and the 5 days before and 4 days after the ovulation date, including the ovulation date, are called the ovulation period. It is recommended that the woman use “ovulation test paper” and ultrasound to monitor ovulation together, so as to determine the ovulation day more accurately. If necessary, assisted reproductive technology can be used. After the above-mentioned preparation, more than 85% of the male partners can try to get pregnant. However, if the female partner is still not pregnant after more than 1 year of trying to conceive without using contraception, she is considered to be infertile. In this case, you should come to the reproductive medicine center as soon as possible, and if necessary, you can choose assisted reproduction techniques such as artificial insemination and IVF under the guidance of a doctor to improve the success rate of pregnancy.
