The full liberalization of China’s two-child policy, some male friends can not wait to join the ranks of preparation for pregnancy. But to conceive a healthy and perfect baby is not the woman’s business alone, the man’s responsibility is also very important. So it is especially important to improve the quality of male sperm. 1, hasten to quit smoking and banning alcohol Foreign studies have shown that smoking can increase sperm DNA damage; increase aneuploidy sperm; tobacco has more than 20 kinds of harmful components, they can directly kill germ cells, but also inhibit the generation of sperm, affecting the male erectile function. Men who smoke for a long time have a high rate of sperm deformities, low sperm motility, erectile dysfunction, and a high rate of fetal malformations. Avoid excessive alcohol consumption. Research data show that drinking alcohol in less than moderate amounts has little effect on fertility. So it is recommended that couples of childbearing age take a “mountain forest” for three months before giving birth! 2, away from radiation and toxic chemicals Modern society, electromagnetic radiation is almost everywhere, such as induction cookers, computers and cell phones, etc., which brings convenience to our lives, but also has a negative side, which is to affect the quality of male semen. Radiation is inversely proportional to the cube of the distance, the distance increases by a factor of 1, the radiation attenuation is 1/8, so you need to stay away from radiation to improve the quality of male semen. There are many chemicals in life that affect male fertility; some chemicals can also interfere with the human endocrine system, so these chemicals are also known as endocrine disruptors (EDs), endocrine disruptors (EDs) are mainly Atrazine (Atrazine, which is a pesticide), octylphenol (Octylphenol), DDT, bisphenol A, tetraoxydiphenyl Dioxahexadiene, etc., away from toxic chemicals in order to improve the quality of male semen. 3, avoid genital local high temperature and high fever (1) hot bath, less washing point: research shows that mammalian testes spermatogenesis needs temperature should be less than 37 ℃, if the local temperature increases, such as sauna, or long-term wear tight underwear will make the local temperature rise, which will affect the male semen quality. So we advise all the prospective fathers to take less hot baths. (2) Tight pants, throw aside: tight pants, jeans seem to be a lot of male friends of the favorite ha, but want to be a father, it is best not to wear too tight pants, of course, do not wear too tight underwear. Too tight pants, synthetic materials, and too high temperatures have all been shown to affect male fertility. (3) Fever should be seen early, don’t carry: high fever may also affect the quality of male semen, some data show that if the fever exceeds 39 degrees, some sensitive men’s spermatogenic function may be inhibited for up to half a year. Small-scale foreign studies show that high fever affects sperm DNA integrity, and some foreign IVF centers suggest that patients should preferably undergo IVF treatment 2 months after high fever. 4, balanced diet, how to eat a good sperm Some men think that eating a lot will ensure nutrition. In fact, this idea is too one-sided, nutrition comes from a variety of foods, and men who are preparing for pregnancy should not only eat a lot, but also eat a variety of food. Especially with the sperm production and maturation related trace elements zinc, selenium, once the lack of, will make the sperm production decreased, which led to the sperm deformity rate increased. 5, weight control, move up The latest research shows that exercise helps to improve male body androgen, and can improve semen quality. Too much or too little body fat can disrupt the normal production of sex hormones, which will lower sperm count and increase the percentage of abnormal sperm. Therefore, if you want to be a father, get moving and keep your body weight within the normal range so that you can produce plenty of high quality sperms! Walking, swimming, table tennis, badminton, basketball, etc., every day at least 30 minutes of exercise, the effect will be good. 6, excessive fatigue to avoid, maintain a good mood is very key If you are ready to have a baby, the father-to-be must pay more attention to rest! Continuous night work, long-distance travel, excessive physical labor, strenuous sports, too concentrated and persistent mental labor and other excessive fatigue conditions are not suitable for conception. If you plan to make a man, you should choose both full of energy, mood when the conception is better. 7, cleanliness, to avoid the attack of reproductive infections Male and female reproductive health is the basic premise of preparation for pregnancy. The more common infections that affect sperm abnormality are prostatitis, seminal vesiculitis, urethritis, orchitis, epididymitis and so on. So all the fathers-to-be must be clean to avoid reproductive infections.
