”In the beginning of man, nature is good.” Nature is innate, without goodness or evil, and flourishes with the growth of human life, and withers with the passing of human years. The ancestors of the country paid attention to this phenomenon of life, recorded its experience, improved its theory, and raised it to the height of health care. There are many things that can be learned from it today, but also many flaws that can be freely speculated. People today can take their time to browse through it and pay attention to what they can discard. Today, we can find this description in the Yellow Emperor’s Classic of Internal Medicine: “If you know the seven losses and eight benefits, the two can be adjusted, but if you do not know how to use this, you will be prematurely declining.” (Suwen? It was only in 1972 that the authoritative commentary was found in the Mawangdui pile in the book “The World’s Greatest Way”. The seven losses and eight benefits actually refer to the matters that are beneficial and harmful to the human body in sexual intercourse. The “seven losses” refers to the seven points of closure, drainage, exhaustion, do not, annoyance, extinction, and expense. Among them, “closed” refers to the pain of the penis during sexual intercourse, the sperm passage does not pass, and even no sperm can be diarrhea. The “leak” refers to the sexual intercourse sweat dripping more than, resulting in Yang Qi out; “exhaustion” is that the sexual life is not restrained, intercourse is not excessive, in vain to make the semen wasted. “Do not” refers to impotence and inactivity during intercourse. The “annoyance” refers to the shortness of breath, shortness of breath and confusion during intercourse. “Never” means that when the woman has no sexual urge at all, the man is sexually impatient and forcible intercourse will bring great pain to the woman, which will not only damage her physical and mental health, but also affect the merits of fetal pregnancy. The “fee” refers to the intercourse when the rush to fast, indiscriminate diarrhea, in vain to dissipate the essence of only. The “eight benefits” refers to the eight items of “treating qi, frothing, knowing the time, storing qi, harmonizing froth, accumulating qi, holding winnings, and fixing the time”. The “treatment of qi” refers to the fact that before sexual intercourse, one should make adequate preparation and practice qi conduction to make the qi and blood flow around the body. “To foam” says that the tongue contains fluid, swallowed from time to time, can nourish the body; also refers to its Yin fluid, is also indispensable for intercourse. “Know the time” is to master the timing of intercourse, which is called. The “storage of gas” is to store up the essence, so that the strong to endure the semen does not diarrhea. “and foam” refers to the swallowing of saliva, the two sides in the intercourse is very coordinated. “Accumulation of gas” six benefits is to say that intercourse can be stopped, not exhausted, in order to accumulate essence. “Hold win” is to say that when the intercourse left room to keep the essence full, so as not to hurt the vital energy. “fixed” is to say that when the two sexes have sex, the man should not love more than happy, that is, to prevent the dumping of the meaning. This “seven losses and eight benefits” is very beneficial to health, to maintain the physical and mental health of men and women, to reduce women’s diseases, and even the next generation of eugenics, have positive significance. The ancients had a unique holistic world view of nature and heaven. According to the Zhou Yi, “Heaven and earth feel and everything is born,” and “clouds and rain are popular, and everything in the universe is the result of the induction of heaven and earth. For human beings, it is also the same, “the two qi induction to meet”, male and female Yin and Yang induction and two affinity, so that people can reproduce. Sun Simiao of the Tang dynasty wrote a piece of “Tonicity in the Room” in the “Thousand Gold Essentials”, suggesting that “the intention of sexual intercourse is to tonicity to dispel illness”. It elevates the daily sex life to the height of the health of the room. In the “Thousand Gold Essential Formula” and “Thousand Gold Wing Formula”, he made a lot of researches on the health care of sexual intercourse. He proposed that sexual intercourse is a science, a “way”, a “method” and a “technique” to be understood, learned and mastered. For different age and physiological characteristics, the strength and weakness of innate vitality, there should be different points of attention for sex. “The youth should be cautious” and “when you reach forty, you should know the art of the room”. If you have not yet reached forty, “greed has not yet ceased, and bait tonic, to take advantage of the room, less than half a year, the essence of depletion, towards the death of near”; if you are past middle age and do not know the essence, “room to repel disease” technique, it is close to early death. Secondly, Sun Simiao and from the perspective of health in the room put forward with the heaven and earth season related to the taboo of sexual intercourse . For example, “when the sky is windy, rain, fog, cold, heat, or lightning, darkness, the sun and moon, the rainbow, etc., can not have intercourse.” Also put forward the different physical conditions of sexual life points of attention. After the disease, the body is weak, do not have sex. Where the fever, sickness or after a long illness, the body has not fully recovered, weakness, do not force the room. Most of these opinions and recommendations are scientific and hygienic way. In the accumulation of experience in sexual medicine and the collection of literature, it has made a great contribution. Because the study of sex in ancient China, often stay on the detailed observation, scientific research is less. For many aspects of sexual knowledge there are still many limitations. This has led to folk legends that mislead the public with falsehoods. For example, folklore says: “One drop of sperm, ten drops of blood.” “to form to complement the shape, eat animal whips, improve the quality of sex life”, etc., today it seems to be very absurd. 1, semen is made up of sperm and seminal plasma. The actual sperm is produced in the testicles of the man, and the seminal plasma is a mixture of fluid secreted by the seminal vesicles, prostate gland, urethral gland and other accessory gland. The semen contains more than 90% water and a small amount of protein, lipids, sugar, enzymes, inorganic salts and trace elements such as zinc. Blood originates from hematopoietic stem cells, and its main hematopoietic organ is bone marrow. Blood consists of red blood cells, white blood cells, platelets, hemoglobin and other plasma components and serum. The sperm production and blood production belong to two different systems in the human body. 2, men from fourteen or five years old, the testicles began to produce sperm, and then stored in the epididymis. When a man has sex, the amount of semen discharged per ejaculation is usually 2-6 ml. Even without having sex, young men will overflow semen through seminal emission or masturbation, etc. Through this semen excretion, the sexual accumulation and tension on the human body will be relieved and released, which can promote metabolism and is beneficial to physical and mental health. Therefore, these components of semen are not mysterious and can be constantly replenished through diet and normal human metabolism. Therefore, the previously proposed holding back semen without ejaculation is absurd. For the frequency of sex, there is no need to worry about frequent, and affect the health. It is generally recommended to not affect the next day’s work life. 3, for eating animal genitalia to improve sexual function, it is also difficult to find the basis of modern science. The external genitalia of animals are composed of proteins, amino acids, fats, and trace elements. Although it contains androgens, but often in the cooking, the destruction of its chemical structure, thus losing its effective role. The Chinese medicine “shape to complement the shape” treatment alone, hoping to eat animal whips to improve sexual performance, will undoubtedly be the moon in the water, the bamboo basket of water. Time into the twenty-first century, the science of prosperity, information flourishing, people in the life of the sexual knowledge that can be reached, but also not thousands of years ago the first people comparable. To avoid harm, to avoid weaknesses, to absorb the essence of tradition, to set aside the fog of sexual mystery, to abandon the fallacies of the past, and to accept a reasonable lifestyle. We can make our families more harmonious and healthy. This is perhaps the purpose of today’s research on sexual medicine.
