On October 29, 2015, the Fifth Plenary Session of the 18th Party Central Committee closed, the country fully liberalized the “two-child policy”, the day the “circle of friends” was “screen”, WeChat, microblogging appeared on the The first time I saw a couple, I was very interested in the idea of having two children. So, what homework should men do if they plan to have another child and raise a healthy, smart baby? The following is an introduction to the preparation and examination to be done by men before childbirth. A, improve lifestyle, quit bad habits 1, quit smoking, quit drinking, and stay up less; 2, avoid sedentary, high temperature: avoid wearing tight underwear and jeans, soaking in hot springs, sauna, etc.; 3, avoid contact with toxic chemicals and radiation: pesticides, insecticides, heavy metals, food additives, etc.; 4, avoid emotional tension and anxiety; 5, reasonable diet: eat more eggs, milk, beef, mutton, corn Walnuts, oysters, apples and tomatoes and other fresh fruits and vegetables, try to avoid spicy food and genetically modified foods; 6, moderate physical exercise: half an hour to an hour of exercise every day, such as jogging or walking, to enhance physical fitness; 7, regular sex life: as long as the woman is not in the menstrual period, should adhere to every 3 to 4 days to have sex. During the female partner’s ovulation period, having sex once a day or every other day can improve the success rate of natural pregnancy. The first one is the first one to be born, so you don’t have to do any tests again, right? The answer is no. The first thing that you need to do is to get a pre-baby checkup, and many people think that you can skip this part. The traditional idea is that people who did not have eugenics checkups in the past were normal and did not have any problems, so it is the same with or without the checkups. In fact, this is a wrong view, the previous not to test on the one hand is technically unable to reach, on the other hand is not enough attention, and with the progress of society, we gradually realize the importance of eugenics examination. Most of the male friends who are ready to have a second child have already entered middle age and their body functions have started to decline. In addition, with busy work, lack of exercise, social and life pressures, as well as food safety and environmental pollution, many people are in a subhealthy state and even suffer from some chronic diseases, such as hypertension, hyperlipidemia, hyperglycemia and hyperuricemia. Therefore, eugenics screening is important. First of all, it is recommended to do a comprehensive eugenics examination, including general condition, cardiovascular, nervous system and genitourinary system examination, such as chest X-ray, electrocardiogram, ultrasound of abdomen, urinary tract and scrotum, blood, urine and stool routine, blood sugar, blood lipid, liver function, kidney function and thyroid function, etc. Of course, the main thing is semen examination, which is one of the simplest indicators directly reflecting male fertility, including semen volume, liquefaction, Ph value, sperm concentration, total sperm count, vitality and normal sperm morphology, etc. If possible, further biochemical or immunological examination of seminal plasma can be done to understand the function of the accessory gonads and whether there is immunological infertility. The actual fact is that you will be able to get a lot more than just a few of these types of things. Urinary tract diseases, such as prostatitis, prostate enlargement, urinary tract infection and mycoplasma and chlamydia infections, should be treated promptly and early to avoid affecting fertility. If the sperm quality is not good, then targeted treatment, a course of treatment is 3 months, if the treatment is not good, assisted reproductive technology is feasible.
