It is said that having a boy is like China Construction Bank, and raising a girl is like China Merchants Bank. Since the country opened the two-child policy, many families have been working hard to have a second child. More and more families hope to have a girl, because a girl is not only a caring little cotton-padded jacket, but also there is no need to consider buying a house or a car for her in the future, which can reduce some of the family’s burden. So how can you conceive a girl? There are two different types of chromosomes in sperm: X chromosomes and Y chromosomes. The X chromosome moves more slowly, but has stronger vitality and ability to adapt to the environment. Compared to the Y chromosome, which carries male genes, the X chromosome survives longer. X sperm (sperm carrying an X chromosome) is the key to having a baby girl. Only by accurately grasping the time when the X sperm combines with the egg after the egg is released and the Y sperm (sperm carrying the Y chromosome) is weakened or dead, can a girl be guaranteed to be conceived. The best time for mating is about 3-4 days before ovulation. Once the exact time of ovulation is determined, the couple should try to have sex a few days before ovulation, and never have sex on the day of ovulation or the next day. Sexual intercourse before ovulation can make Y sperm lose their activity and die in large numbers before they combine with the egg, allowing the egg to combine with the X sperm, which has stronger vitality. This method can increase the possibility of conceiving a girl. The posture must be correct: The vaginal opening is the most acidic area in the female vagina, and Y sperm is very fragile and easy to die in an acidic environment. Because Y sperm cannot survive easily under acidic conditions, if couples can control the sex position during sexual intercourse and only perform shallow and slow thrusts, they can reduce the number of Y sperm passing through the vagina, thereby reducing the chance of Y sperm combining with the egg. The environment needs to be "acidic": Y sperm can survive well in alkaline environments, but in acidic environments, the activity of sperm will be weakened and destroyed. X sperm can survive well in acid and alkaline environments. Therefore, maintaining the acidity in the vaginal cavity can increase the possibility of conceiving a baby girl. During orgasm, the acidity in the vagina will decrease. In order not to miss the "good opportunity", couples should try to avoid orgasm during sex. Preventing women from having orgasms, or delaying the time of orgasm, can maintain the acidity in the vagina, reduce the number of Y sperm that can eventually reach the egg after a long journey, and create a better chance for the final combination of X sperm and egg. |
