The most prominent features of a baby girl

The most prominent features of a baby girl 1. Ovulation period: Generally, sperm with Y chromosomes have strong motility, but poor endurance, are easily harmed by adverse external factors, and have a short survival time; while sperm with X chromosomes have poor motility, good endurance to adverse environments, and can survive and maintain fertilization ability for a longer time. Therefore, the closer to the ovulation period, the greater the possibility of a male fetus. 2. Acid-base environment: Sperm with X chromosome prefers acidic environment, while sperm with Y chromosome prefers alkaline environment. Therefore, adjusting eating habits, eating more vegetables, and flushing the vagina with a weak alkali diluted solution can increase the probability of having a boy. 3. Stress factors: Long-term stress in men will reduce the number of sperm; excessive tension in women will create a strong acidic environment, which is not conducive to the survival of Y sperm. Therefore, people who are under too much pressure at work or have great pressure to have children are particularly likely to give birth to girls. If you want to have a boy, don't put too much pressure on yourself and just relax. 4. Sexual intercourse time: X sperm can survive for 2 to 3 days (within 72 hours), while Y sperm can survive for about 24 hours. If both X and Y sperms swim to the ampulla of the fallopian tube to wait for the arrival of the egg, the possibility of having a girl is greater at this time, because the X sperm survives longer; if the egg has been discharged into the ampulla of the fallopian tube, the Y sperm always arrives first, so the possibility of having a boy is greater. If the sperm and egg reach the ampulla of the fallopian tube at the same time, the probability of having a boy is greater. 1. The frequency of sexual intercourse should be frequent. Couples who want to have a daughter do not need to control the frequency of sexual intercourse before the last intercourse. Because the more times you have sex, the fewer Y sperm you will have. But while sex doesn't have to be moderate, it also can't be excessive, so as to avoid over-exerting the husband's energy. In addition, the man’s age will also affect the gender of the baby. According to preliminary statistics, a man's sperm count decreases with age, so the chance of having a girl is particularly high; similarly, the older a woman is, the higher her chance of having a girl. 2. Having sex 2 days before ovulation In order to have a girl, the most important thing is to have sex with the purpose of conception 2 days before ovulation. Therefore, the basal body temperature method must be used first to determine the ovulation day. Also, even if you have found your specific ovulation day, some people still feel uneasy. So, please don't be too nervous. If you keep recording your data leisurely for 3 months, you will find that your body temperature will drop suddenly on a certain day of every month. This is the day of ovulation. For example, if the fourteenth day after the start of menstruation this month is the ovulation day, then the 2 days before ovulation, which is the twelfth day after menstruation, is the conception day if you want to have a girl, which is also the day for having sex. 3. If you have sex every 3 days before conception, the sperm that produces a girl is X sperm, but the number of X sperm is relatively small compared to Y sperm. That is to say, if the total number of sperm is higher, the number of Y sperm will be higher, and of course the possibility of combining with the egg in the uterus will be greater. On the contrary, if the total sperm count is reduced, the number of Y sperm will also decrease, so the possibility of Y sperm combining with the egg will also decrease. Therefore, this problem can be regulated by having frequent sexual intercourse from the end of menstruation to the day of sexual intercourse for the purpose of conception. However, if you have intercourse too frequently, by the time of your destination, your sperm count may be reduced to a level that makes pregnancy difficult, so there should be a limit to how frequent intercourse you have. So, how many days interval is better before having sex? This depends on individual differences, and it is difficult to come to a definite conclusion. According to a survey, many people who successfully gave birth to girls usually have sex every 3 days. Perhaps this frequency can keep the number of X sperm and Y sperm balanced. However, during this period of time, you must use condoms for contraception. 4. Shallow penetration during intercourse can reduce the number of Y sperm that reach the uterus, leaving more X sperm. Shallow penetration during intercourse is a necessary principle for having a girl. Therefore, male ejaculation must be performed with the male penis inserted as shallowly as possible. In this way, the distance and time from sperm ejaculation to reaching the entrance of the uterus will be extended, the acid-intolerant Y sperm will gradually lose its vitality, and the acid-resistant X sperm will have a higher rate of reaching the uterus. You also need to put some effort into the posture during intercourse. When the union of man and woman is shallow, the male's penis will not penetrate deeply. For example, the woman stretches her legs and the man is on top in an elongated position, or both men and women lie on their sides or face to face, all of which are suitable for shallow penetration. 5. Make the vagina acidic X and Y sperm swim at different speeds in environments with different pH values; Y sperm swim faster in alkaline environments, while X sperm are more active in acidic environments. Therefore, if a couple hopes to have a girl, they can take advantage of the acidic nature of X sperm and make the vaginal environment acidic, which can increase the possibility of having a daughter. Before sexual intercourse, the woman can also dilute acetic acid with a small amount of clean warm water and then rinse the vagina to create an acidic environment, which will help with the birth of a girl. 6. The woman should avoid orgasm. The vagina of a normal woman is usually strongly acidic (pH 3.8-4.2). After the first orgasm, it becomes acidic (pH 5.2-6.0). After the second orgasm, it will change to weakly acidic (pH 6.3-6.8). Because semen is alkaline (pH 7.4-7.8), and when you reach orgasm, the alkalinity of the vagina will be enhanced. In addition, the alkaline environment is more suitable for the growth of Y sperm. Therefore, if you want to have a daughter, you should try to avoid orgasm to reduce the chance of enhancing the alkalinity of the vagina. What are the characteristics of a man who is pregnant with a baby girl? 1: Men who smoke a lot of cigarettes every day. According to British research data, if only one of the man or woman smokes, the chance of having a girl will increase. Moreover, the chance of having a girl is directly proportional to the smoking addiction of both husband and wife. The more they smoke, the smaller the chance of having a boy. 2: Men with many sisters According to a study published in the British journal Evolutionary Biology, the probability of a man having a girl is also related to his innate genes. Specifically, if a man has many sisters, his sperm is more likely to carry X chromosomes, making it easier to have a girl. The study was conducted by Newcastle University in the UK. After comparing thousands of families, they found that men with more brothers are more likely to have sons, while men with more sisters are much more likely to have daughters. 3: Older men According to a study published in the British journal New Science, a man's sperm will change with age, and this change will affect the chance of having a boy. In other words, the older the man, the easier it is to have a girl. The study was conducted by experts at the Fertility Technology Laboratory in Los Angeles, USA. They monitored semen samples from more than 5,000 men. In the tests, they found that the older the man was, the fewer sperms with Y chromosomes were present. This trend reverses after the age of 55. 4: Men who are tired all day have sperm with Y chromosomes. Although they are faster, their survival time and ability to adapt to the environment are relatively poor. If a man often stays up late and works overtime, the sperm carrying the Y chromosome may die due to lack of tolerance. Therefore, for some men who engage in high-intensity jobs (such as drivers and pilots), the probability of them giving birth to girls is significantly higher than the probability of giving birth to boys. 5: There are rumors that more than 80% of men working in the IT industry will have daughters. Although this statement is a bit exaggerated and the argument is not absolutely scientific, it at least gives us a signal. We know that the survival time of X and Y chromosomes is different. For men working in the IT industry, the sperm motility tends to decline under the condition of radiation and excessive brain use. At this time, the sperm with the Y chromosome loses its speed advantage, and the sperm with the X chromosome has an advantage in survival time. Under these circumstances, the sperm with the X chromosome is more likely to combine with the egg. The above are all the most prominent characteristics of pregnant with a baby girl. I hope it will be helpful to everyone. I also hope that everyone will support Ziwei Mansion. |
