If you want a lively boy or a beautiful girl, you don’t have to let God decide. Since every father and mother-to-be has expectations and visions for their little ones, they can make their own decisions about the sex of their children! The methods collected here from the Internet may really help you to get what you want. The mystery of the male and female 1, a battle for the eggs You must not think that the birth of a small life in the man after ejaculation is a great success, the next process of hard work, perhaps thousands of times more than sex on the battlefield. Every time you have sex, there are billions of sperm crossing the vagina, cervix and uterine cavity to an egg, and just as males have had to compete in courtship for billions of years, each sperm has to face many rivals and undergo a powerful test from the egg – the “zona pellucida “These are the two lines of defense that prevent the sperm from penetrating the egg. The sperm will release three hydrolytic enzymes such as radial crown penetrating enzyme, hyaluronidase, and proteolytic enzyme to break through the egg’s defenses, so that the strongest sperm is the first to go and becomes the winner of the union with the egg. After the egg is penetrated and fertilized by the first sperm, it will automatically release a substance to stop other sperm from entering and start to grow intently in the human body. 2. Y sperm = boy? X sperm = girl? Among the 23 pairs of chromosomes in the human body, one of them is the sex chromosome that determines the sex of the embryo. A woman can only produce an egg with sex chromosomes, but a man can produce sperm with two sex chromosomes, one with sex chromosome X and one with sex chromosome Y. When the egg is combined with the former, the fertilized egg is XX type, giving birth to a girl, and vice versa, the fertilized egg is XY type, giving birth to a boy. So, in this battle for the egg, whether X or Y sperm wins becomes the key to having a boy or a girl. 3. Acid-loving X sperm, alkaline-loving Y sperm (1) Y sperm are more numerous but less resistant; X sperm are less numerous but more resistant. (2) In the acidic environment of the vagina, the activity of both X and Y sperm will be inhibited, but the resistance of X sperm is strong, so X sperm have a better chance to combine with the egg and are more likely to have a girl. (3) In the alkaline environment of the vagina, both X and Y sperm have good motility, but Y sperm have a higher chance of having a male child because of their “sperm abundance”. How to have a boy or a girl? The key is to take advantage of changes in vaginal pH. There are many ways to do this, but you need to be prepared beforehand, and their chances of success are around 80%. The main methods are: 1. Calculate the ovulation date The closer to the ovulation date, the more alkaline the vagina and uterus are, so the higher the chance of Y sperm and egg combination, the more likely to have a boy, and vice versa, the further away from the ovulation date, the more likely to have a girl. The formula for calculating the day of ovulation: the first day of ovulation = the shortest number of days of a menstrual cycle – 18 days, the last day of ovulation = the longest number of days of a menstrual cycle – 11 days, before using this formula, I have to observe and record my menstrual cycle for 8 times in a row, and come up with its longest and shortest number of days, and substitute the numbers to indicate themselves respectively The beginning and end of the “ovulation” period. (The menstrual cycle is calculated from the first day of this period to the first day of the next period). If you have regular periods, let’s say 28 days, then you can set the longest and shortest days of your menstrual cycle as 28 days and substitute the formula to calculate your “ovulation period” as the 10th – 17th day of your current period. If your period is irregular, then use ultrasound to check it, which is the most accurate method. 2. Acidic food and alkaline food Using food therapy can control the pH of the vagina. If you want a male baby, you should eat more alkaline food before conception, and vice versa, if you like a girl, you should eat more acidic food. Does acidic food mean food that tastes sour? Of course not. A tomato tastes sour enough, right, but it is an alkaline food. To determine whether it is an acidic or alkaline food, it lies in whether the result of metabolism of this food in the body is acidic or alkaline, which is a physiological concept that has nothing to do with taste and chemical concepts, so let’s see which are the real acidic and alkaline foods. Acidic foods: rice and other carbohydrates, meat, poultry, aquatic products, eggs, peanuts, walnuts, etc. Alkaline foods: vegetables, root vegetables in grain (such as potatoes, sweet potatoes), fruits, milk, nuts in the chestnut, almonds, etc. 3, sex position and ejaculation time A Japanese high school biology teacher, Mr. Supervisor see as early as 1966, found that as the prelude to sexual intercourse unfolds, the vagina gradually from acidic to alkaline, when the vagina begins to excite the initial period, the pH of the vagina is still 6.4, within the acidic environment, when reaching orgasm, the pH of the vagina will reach 8.4-8.8, showing alkaline, after this, and gradually turns to acidic again. Therefore, Mr. Supervisor says that if a husband ejaculates during his wife’s orgasm, there is a 90% chance that she will conceive a boy. Therefore, to get a cute baby boy, more foreplay, the man can not be lazy and anxious Oh, you have to give full play to your mouth and tongue and ten fingers, so that the wife HI up, love fluids dripping to enter the actual battle stage. On the contrary, if you want a beautiful and beautiful baby girl, the couple should miss the orgasm time, the husband early into the wife ejaculation. Another mystery is that the position of sex can also determine the sex of the future little life. If you want a boy, you should try to create conditions for Y sperm to swim less distance, so choose a position that combines deeply with the loving couple. For example, the flexion position and the back position. The flexion position is the man on top of the woman, the wife’s legs as far up as possible, bending knees, or even on the husband’s shoulders, so that he deep inside. Or in the back position, the wife lies on her back or kneels on the bed while the husband holds his wife’s waist and enters from behind. If you want a cute little princess, it’s time to go shallow, as this will allow the Y sperm to die halfway and create more opportunities for the X sperm. You can take the flat and side lying position, let the wife lie on her back, legs together, straight, the husband on top, the weight of the body as much as possible do not press on the wife, enter will not be too deep; side lying position is the couple face to face side lying combined position, can also achieve the effect of ejaculation in the shallow. 4, to the vaginal bath Many years ago, the German medical doctor Utah Burga in order to treat infertility patients, the use of 2% bicarbonate of Na solution to douche the vagina, the unexpected harvest is that those women who received treatment, most of the births are male babies. In the first year of treatment, there were 53 successful pregnancies and all of them were male babies. So, douching the vagina with bicarbonate of soda solution became the classic method to induce the birth of a boy. It is no coincidence that to have a girl, you can choose to douche the vagina with acetic acid solution, this is to make the acid-fearing Y sperm less active. Sex is best scheduled 2 days before ovulation day, when the vagina tends to be weakly acidic but weaker than the normal state, so it needs to be artificially strengthened with vaginal acidity. Flushing can be done about 15 minutes before sex for 1-2 minutes. Where to buy both solutions Sodium bicarbonate solution and acetic acid solution are available in hospitals. You can also make your own acetic acid solution by buying a bottle of white vinegar, preparing an acetic acid solution with a 5% concentration, i.e. 50 ml of white vinegar in 1 liter of water, and douching with a vaginal douche. Tips:Other factors that affect the birth of boys and girls: 1, metal elements Professor Storgowski, a biochemist at the University of Paris, as early as 1963, with frogs and sodium, potassium, calcium, magnesium ions to do experiments with sodium, potassium as a group, calcium, magnesium as a group, were placed in two pools to incubate frog eggs. It was found that most of the frogs hatched in the pool with sodium and potassium ions were male, while most of the frogs in the pool with calcium and magnesium ions were female. Based on this principle, Professor Storgowski also worked out a recipe for controlling the sex of the fetus in 1972. He conducted secret experiments on 38 volunteer mothers-to-be and succeeded in all but six cases, which failed. The reason why those 6 cases failed was also caused by not strictly following the diet. 2, nutrition Scientists in 1884, based on a large number of observations and statistics, pointed out that women in malnourished conditions more boys, and vice versa is more likely to give birth to girls. Specifically, it is when the proportion of grain and vegetables in the food is large, easy to give birth to boys. If the proportion of eggs, fat, meat food is significant, it is easy to have a girl. If you pay attention to observe, it is not difficult to find around which most obese couples give birth to girls, the majority of thin couples give birth to boys. 3, family genetics Some scientists have done a special family genealogy investigation. In the United Kingdom and France respectively, there are two very special genealogy, the British genealogy of the 10 generations of 35 children in 33 boys, only 2 girls, and 2 girls in 1 died young, and 1 is a hermaphrodite. Scientists’ explanation is that because most of the male sperm in the family is Y sperm, while X sperm are rare or weak, so only boys can be born. Another French genealogy is the opposite, with 72 children born in three generations all female. Scientists believe that this is inherited through the women, whose eggs can only combine with X sperm and not Y sperm, and so give birth to clear female babies. It is recommended that those who want to have a boy first check the quality of sperm, can take Chinese herbal medicine to improve the quality of sperm, especially sperm vitality, and give the woman also take Chinese herbal medicine to improve her level of desire, using basic body temperature measurement, date projection, ovulation test paper detection and ultrasound monitoring methods to determine the ovulation day, using appropriate techniques to stimulate the female orgasm, combined with the use of With the above methods, you can expect to have a “baby with a handle” and a super smart baby. Of course, these methods may not have very certain results. Both boys and girls are treasures, so let’s just let nature take its course.
