Eugenics is the hope and responsibility of every family, and if a couple is ready to conceive a healthy baby, they should start preparing 3 months to a year in advance. If you act earlier, the higher your chances of getting pregnant and also increase the chances of conceiving a healthy little baby. 1. Diet: Your diet should be as balanced and nutritious as possible. For men: (1) Eat plenty of foods rich in vitamin C and antioxidants, as vitamin C and antioxidants reduce the risk of sperm damage and improve sperm motility. One glass of orange juice contains 124 mg of vitamin C. Get at least 60 mg of vitamin C a day, and if you smoke, then you should get more vitamin C, at least 100 mg a day. (2) Increase the amount of zinc in your diet to at least 12 mg to 15 mg per day. Foods rich in zinc include lean beef (1 tael of beef contains 4, 5 mg of zinc), and oyster meat (1 tael of oyster meat contains 2, 38 mg). (3) Increase the intake of calcium and vitamin D. Infertility researchers at the University of Wisconsin imply that taking 1,000 mg of calcium and 10 micrograms of vitamin D daily can improve male fertility. Calcium-rich foods include low-fat milk and cheese. Milk and salmon contain vitamin D. (4) Stop or reduce alcohol consumption. Studies have shown that daily consumption of wine, beer or spirits reduces testosterone levels and sperm counts and increases the number of metamorphic sperm in the ejaculate. (5) Stop taking stimulants, such as marijuana and cocaine. Marijuana decreases sperm motility and cocaine affects the chemicals in the brain that determine the release of reproductive hormones. Drug use can also lead to fetal malformations. For women: (1) Reduce artificially sweetened condiments, gradually move away from caffeine, soda, and coffee (300 mg of caffeine per day can reduce the ability to conceive by 27%), and stop drinking alcohol or drink only occasionally. Stop taking all kinds of stimulants. (2) Take vitamin supplements and adequate folic acid: at least 400 mg per day. It is recommended to start taking Elavil 6 months before pregnancy. (3) Women who have been taking oral contraceptives for a long time should stop using them for two months before conceiving. (4) Avoid contact with pets. 2. Life factors: (1) Avoid hot tubs, saunas and tight clothing. Steam sauna equipment, tight jeans, synthetic shorts, and bikini underwear can overheat your testicles and inhibit fertility. To protect your testicles, wear loose fitting pants and baggy shorts. (2) Stress. Research from the Department of Physiology at the Medical College of Ohio has shown that even a small amount of stress can cause a decrease in testosterone levels and sperm counts in men. Reducing stress can improve your sexual performance. (3) Risk factors in the workplace. Research at Montreal’s McGill University says that exposure to radiation and chemicals can cause damage to sperm, a drop in sperm count, and genetic defects in babies. If you are exposed to any harmful substances at work, ask to be temporarily transferred to another job. (4) Certain medications. Many medications can cause decreased fertility and sperm counts, including medications for high blood pressure, ulcers, cancer, heart disease, colitis, and even viral infections. Consult your doctor about whether the prescription drugs you are taking have side effects on sexual performance. (5) Stop smoking. Recent studies have determined that men who smoke have lower sperm counts. Moreover, passive smoking is more harmful to your wife and unborn child. 3. Pay attention to the following situations where conception is not advisable (1) A man over 55 years old or a woman or over 35 years old should not get pregnant. The incidence of malformation and imbecile children will be significantly higher if the child is born beyond the above age. (2) When you are ill or recovering from an illness, you should not conceive. (3) It is not advisable to conceive when you are mentally uncomfortable. (4) When you are overly tired, you should not conceive. In particular, newlyweds should strengthen contraceptive measures during travel. (5) You should not conceive while taking medication for chronic diseases. (6) You should not conceive after drinking alcohol. Alcohol can damage germ cells and lead to fetal malformation or imbecility. Some data show that 60% of fetuses conceived after drinking alcohol are congenitally mentally retarded. In general, the male sperm cells develop into mature sperm, it takes about 80 days, and couples who are about to conceive offspring must quit smoking and drinking during this time. (7) Conception is not advisable after heavy smoking. (8) It is not advisable to conceive after radiation treatment or exposure to harmful substances. (9) It is not advisable to conceive from early winter to early spring. Because early pregnancy is the most fear of viral infection, once the pregnant woman suffers from it, the rate of malformation increases significantly, and winter and spring are the seasons of viral infection. 4, premarital examination Premarital examination includes detailed health inquiries and family genetic history inquiries by doctors to both men and women, and general physical examination, genital examination and other special examinations. Premarital examination can make both men and women to get the relevant sexual knowledge, eugenics and general knowledge of birth control methods and family planning guidance for newlyweds. If there are serious hereditary diseases and uncorrectable deformities of the reproductive organs can not be married; in addition, there are some people need to suspend the marriage or control the birth of children after marriage. Therefore, premarital examination is an important event for men and women before they get married, which can prevent problems before they occur and greatly reduce the occurrence of genetic diseases. The ideal plan for conception must have a good state of physical and mental health, a harmonious relationship between husband and wife, a safe and comfortable surrounding environment, and relaxed and stable economic conditions.
