I. Physiological preparation 3 months before pregnancy should be both healthy and disease free, either party should not conceive if they are suffering from tuberculosis, hepatitis, nephritis, especially women suffering from heart disease, diabetes, hyperthyroidism, venereal disease, tumors. It is also necessary to wait for 3 months after recovering from the disease before conceiving. Both stop drinking and smoking 3 months before conception. Use medication with caution for all 3 months before conception, including not using estrogen-containing skin care products. Couples who work in occupations that are harmful to the fetus, especially women, must leave temporarily 3 months before conception. Women who have been using instrumental and pharmaceutical contraceptives for a long time should stop using them for 6 months before conceiving. Do not conceive during sexual intercourse while fatigued. Women who are too fat and too thin should adjust their weight to normal. Having a child is a great project and should be planned well before conceiving and not blindly. It is important to be fully prepared for childbirth and to be well prepared to win at the beginning. In order to reduce the nutritional damage caused by the “early pregnancy reaction”, it is important to actively eat nutrient-rich foods such as folic acid, zinc and calcium in the 3 months before you are ready to get pregnant. In the 3 months before getting pregnant, eat more lean meat, eggs, fish and shrimp, animal liver, beans and soy products, seafood, fresh vegetables and seasonal fruits. Men eat more eels, loach, pigeons, oysters, sparrows and leeks. Less into ham, sausage, salted meat, pickled fish, pickled vegetables, do not eat smoked food such as lamb skewers, etc. Eat less canned food and drink less beverages. Wash vegetables with care to remove residual pesticides by dipping and washing methods. The psychological choice to conceive The sexual intercourse with the mission to conceive should be carried out in a happy mood, without depression and worries. The husband should pay attention to and let his wife reach orgasm, which is essential to get a healthy and smart child. Traditional Chinese culture believes that man is a whole united by essence, qi and spirit, and that man is formed and survives by zong qi, what is zong qi? Simply put, it is a kind of energy (bio-energy) that is formed during the movement of a person’s life and depends on it, which cannot be seen by the naked eye, but can be experienced. The qi sinking into the dantian described in qigong refers to this kind of qi. A good mental state will have a beneficial effect on the reproductive cells of both men and women. Therefore, when planning conception, in addition to paying attention to the physical health of both men and women, it is important to choose the time when you are in the best physical condition, most energetic and in the best mood, because the fertilized eggs obtained at this time are also of the highest quality. According to Chinese medicine, people and heaven and earth correspond to each other, and there are many requirements for the environment of intercourse, such as the climate of cold and heat, thunder and lightning, noisy and lively sound, indignant and depressed state of mind, all should avoid intercourse. Modern endocrinology research has found scientific arguments for the timing of conception and eugenics. Recently, the U.S. National Institute of Mental Health published its findings. It is believed that the germination of love between men and women is related to the secretion of pressor and oxytocin by the posterior pituitary gland. In the process of lovemaking, both men and women secrete large amounts of pressin and oxytocin, which, together with the known sex hormones, constitute an internal environment conducive to reproduction, so that ovulation, ejaculation, fertilization, implantation and a series of other links are in line with the characteristics of physiology, and this coordination of endocrine hormones and the stability of the internal environment will undoubtedly enable the fetus to develop and grow well, so that it becomes an individual with good intelligence and physical strength The first thing you need to do is to make sure that you have a good understanding of the situation. If the room environment is bad, moody, or sudden intercourse without bedtime drama, sex hormones, pressor hormone, oxytocin will certainly be secreted low, not only cause mental pain, and at this time conception, various conditions are not available, the internal environment is poor, the fetal development will certainly be affected. Therefore, the timing of conception is very closely related to eugenics. In order for your offspring not to lag behind and become an excellent talent, you should create a superior body, a superior time and a superior environment with all your heart, and I hope that young couples all over the world will benefit from this concept of mine and guide your life.
