Want to give birth to a smart and healthy baby, not only the task of the mother-to-be Oh. Unexpected father for eugenics is responsible for, before giving birth to a considerable period of time, the husband “performance” of the good and bad, the baby has an inestimable impact. 1, living habits in time to change the father before the birth of the child to maintain a good state of health, stay up late will reduce the body’s immune system, should pay attention to reasonable rest; some foods, such as celery, fungus, cottonseed oil, will reduce the vitality of the sperm and the number of sperm should be avoided; hot water, high temperature is not conducive to spermatogenesis, pay attention to bathing water should not be overheated, and don’t go to the sauna; male smoking not only affects the quality of the sperm, will also make the wife passive smoking and affect the embryo, and will not be able to make the baby. Wife passive smoking and affect the normal development of the embryo, should be in the wife before pregnancy after pregnancy for quite some time to quit smoking. Drinking large amounts of alcohol has a toxic effect on the male reproductive system, making sperm count and vigor abnormal. It has been reported that “a month before the wife becomes pregnant, if the husband drinks milliliters of alcohol equivalent per day, or drinks alcohol more than milliliters per occasion in January, or has drunk alcohol more than or equal to milliliters per occasion in January, his wife gives birth to a newborn whose birth weight drops by grams compared to the control group”. Such low-birth-weight babies will not only bring difficulties in feeding, but also be adversely affected in terms of disease resistance, growth rate and intellectual development. 2, fine breeding to maintain In recent years, due to the deterioration of people’s living environment, male fertility is declining. The World Health Organization has issued a warning: people are facing a “fertility crisis”. Some men’s sperm quality and quantity are problematic, resulting in a number of indiscriminate “remnants”. In such cases, the embryos formed are susceptible to spontaneous abortion. Before the couple plans to have children, it is best for the father to do a comprehensive checkup to rule out the suspicion of disease and to check the sperm condition to avoid any problems before taking actions to mend the fold. From the clinical point of view, for men with reduced sperm count, low vitality, etc., after treatment, the number of spontaneous abortions due to sperm quality problems can be greatly reduced. 3, physical disease to be treated If the unexpecting father suffers from physical disease, he should be treated in time, otherwise it will have an impact on the future baby. If the unexpecting father suffers from hepatitis B, positive anti-sperm antibodies, as well as a variety of sexually transmitted diseases, will affect eugenics. For example, hepatitis B, where HBVDNA, HBeAg positive, it is possible to carry through the sperm, fetal infection occurs, so those who suffer from hepatitis B, should be treated after the conversion of fertility; for anti-sperm antibody positive, should also be cured more than one month before giving birth to a child, because commonly used prednisone, dexamethasone have a negative impact on the birth of a child; as long as the detection of sexually transmitted infections, should be seriously treated, and cured before giving birth to a baby. The reason is that prednisone and dexamethasone, which are commonly used, have adverse effects on fertility. As the saying goes, “medicines are three times poisonous”. Before planning to have a baby, the father should be more careful with the use of drugs, do not abuse. Clinical research data show that many drugs on the male reproductive function and sperm quality will have adverse effects, common antihistamines, anticancer drugs, caffeine, morphine, steroids, diuretic drugs. These drugs are prone to cause newborn defects, such as infant developmental delays, behavioral abnormalities, and cranial tumors. Some people think that when they are about to give birth, it will be beneficial for the unexpecting father to take some herbal medicine. Not before the birth of the father should not abuse drugs, have to use drugs, should consult a doctor, even if it is a tonic, but also to determine that there are no side effects can be taken. 5, the harmful environment to stay away from the unexpecting father in a bad environment to live and work, will make the sensitive testicles affected. Studies have confirmed that lead, mercury, cadmium, tin, arsenic, nickel, cobalt, benzene and other elements can have a deleterious effect on male fertility. Exposure to pesticides can cause abnormalities in spermatozoa, leading to miscarriages, stillbirths and neonatal defects, such as benomyl, dibromochloropropane, methylmercury, and heptachlor epoxide, which are all known to have such lethal effects. Data show that pesticide-spraying husbands whose wives become pregnant are prone to accidents and birth of deformed fetuses. Radiation, isotopes, and electromagnetic waves can cause sperm abnormalities in men, resulting in varying degrees of birth defects in newborns. When planning to have a baby, the unexpecting father should temporarily stay away from the above environment. If it is really impossible to leave, he should pay attention to protection at work, operate in accordance with regulations, and raise his awareness of self-care. Once you have a child in an unprotected state, you should pay attention to pregnancy checkups and take timely measures when you find abnormalities. 6, the harmony of the atmosphere need to create the unprepared father to pay attention to the mother’s emotional impact on the fetus, be aware of the poor family environment, tense work pressure, fear of survival, are not conducive to childbirth. Data show that the mother-to-be in the poor mood of the child, easy to appear withdrawn, perverted character. Therefore, it is the husband’s responsibility to maintain a good family atmosphere while his wife is pregnant. Love and harmony between husband and wife is one of the great joys of life and indispensable for eugenics.
