The chances of having a boy or a girl are average, and it is rather difficult to control it. However, there are ways to have a girl. We can do it through in vitro fertilization, or we can do some preparatory measures before conception. First, change the acidity and alkalinity, because the activity of sperm in the vagina is affected by the acidity and temperature. In addition, sexual intercourse is not allowed within three days before ovulation, so the probability of having a girl will be higher. What are the ways to have a girl? 1. Change the acid and alkali Sperm with X and Y chromosomes swim at different speeds in different pH environments: sperm with Y chromosomes are more active in alkaline environments, while sperm with X chromosomes are more active in acidic environments. Therefore, if the couple hopes to have a girl, they can dilute acetic acid with a small amount of clean warm water and then rinse the woman's vagina to make the vagina acidic. 2. Sexual intercourse temperature German researchers tracked birth records between 1946 and 1995 and compared them with local temperature changes. The results showed that April to June were the months with the most baby boys born, while October was the month with the least baby boys born. Further analysis shows that the environmental temperature one month before the fertilized egg is combined, that is, the temperature of the environment in which the boy and the girl are in one month before sexual intercourse, is an important factor affecting the baby's gender. A high temperature environment is more likely to create a baby boy, while a low temperature environment is more likely to create a baby girl. 3. Pay attention to body position Many people know that if you want to have a boy, it is best to have deep penetration during sexual intercourse. So, if you want to have a girl, should it be the other way around, shallow penetration? In fact, there is no doubt that this is indeed the case. If the man adopts the shallow penetration method, the ejaculated sperm will definitely stay in the acidic vagina for a period of time, allowing the Y sperm to be eliminated as much as possible, leaving only the X sperm, thus increasing the probability of having a girl. 4. Stop having sex three days before ovulation Usually on the day of ovulation, a woman's body will secrete a large amount of transparent mucus, which can prevent sperm from entering the uterus and keep them in the acidic vagina. The acidic environment is not suitable for the growth of Y sperm, so Y sperm is eliminated and X sperm is left. After the mucus in the uterus dissolves, X sperm can successfully combine with the egg and give birth to a baby girl. Because sperm can survive in the uterus for 3 days, if you want to avoid fertilization on the day of ovulation, you must stop having sex 3 days before ovulation. |
