Because some genetic diseases are closely related to sex, they are called X-linked genetic diseases. Letting boys and girls decide for themselves is not a myth. It is known that the birth of a boy or a girl is determined by the nature of the sperm. There are two kinds of sperm, one is X sperm and the other is Y sperm. The gender of a child may depend on whether the fertilized sperm is an X or Y sperm. If the sperm and egg are only X, then the sperm and egg will give birth to a girl; if the sperm and egg of Y will give birth to a boy. Through extensive research on the effects of pregnancy on female fertilization, scientists have discovered that many natural factors can have subtle effects on the binding of X sperm during conception. Normally, these factors will continue to act randomly, causing the ratio of women to boys to girls to become pregnant to be approximately 50:50. Some factors independently influence fetal sex selection. But many families are worried about having children. Some like boys and some like girls. So how to make the right switch? Below, the editor of Babao.com will popularize relevant knowledge for everyone.
1. Why are you more likely to have a son in the dog days of summer
Some studies have found that the environment in which men and women live one month before sexual intercourse is different. Temperature will affect the sex of the baby. In a low-temperature environment, the Y chromosome of the sperm will be affected, making it difficult to give birth to a male baby. In a high-temperature environment, the X chromosome of the sperm will be affected, making it difficult. Give birth to a baby girl.
2. What can you do to give birth to a boy?
Know the ovulation period: Having sex close to the woman’s ovulation time will make it easier to give birth to a boy. This is It takes advantage of the characteristics of Y sperm that are active and short-lived and X sperm that are slow but long-lived to artificially create an environment that promotes the successful combination of sperm and egg. Be sure to confirm the ovulation period before having sex, and you can buy test strips; for a normal physique, the time of intercourse is an important factor affecting the birth of a boy or a girl.
Because during or very close to the ovulation period, the secretion in the vagina is relatively alkaline, and during intercourse at this time, the Y sperm (male sperm) representing the boy will have more opportunities to ejaculate first. Combine with the egg and get a boy. On the contrary, two or three days before ovulation, the vaginal secretion is more acidic, and there will be more opportunities for X sperm (The female sperm) first combines with the egg, and a daughter is obtained.
Before preparing to get pregnant, measure your basal body temperature correctly. The day when it suddenly drops is the day of ovulation. If you are not sure, you can go to the hospital to check the cervical mucus to help judge; even if you measure your basal body temperature correctly, some people You still don’t know the day when your body temperature will drop, so try to go to the obstetrician on the possible ovulation day to check the cervical mucus to confirm whether this day is the ovulation day.
Have sex on the day of ovulation or immediately after ovulation, because the faster-moving Y sperm reaches the egg before the X sperm; have sex on the day of ovulation or the next day, because the vaginal secretions are alkaline at this time. Sex is conducive to the survival of Y sperm; if you want to get pregnant after this menstruation, do not sleep with your husband after this menstruation until ten days to half a month later, you feel that the leucorrhea has increased significantly, and both husband and wife When you have a strong desire and are in a very good mood, you can consider conceiving.
Have sex on the day of ovulation, or immediately after ovulation, because the faster-moving Y sperm reaches the egg before the X sperm; the number of sex should be less, because this can increase the proportion of Y sperm. Try to have sex at the beginning and end of the lunar month, that way the chances will be higher.
3. Sexual intercourse secrets to conceive a boy
Time to have intercourse – abstinence (about 5 days) until before ovulation Before ovulation, you can still have normal sexual life, because the cervix is alkaline during ovulation, which is conducive to the survival of Y sperm.
Vaginal pH adjustment – try to be as close to the ovulation period as possible during intercourse, because during this period the female secretions are alkaline, which can help Y sperm move; or start flushing the vagina with soda water three days before ovulation to enhance The alkaline environment of the vagina.
Positions for sexual intercourse – It is said that the woman should reach orgasm during sexual intercourse, which is more likely to give birth to a boy, because when the woman orgasms, the cervix secretes more alkaline secretions, which is suitable for the activity of Y sperm, so the man must The woman should be caressed more.
In addition, a deeper insertion position should be used, because Y sperm is less active inside the vagina. If Y sperm is ejaculated closer to the cervix, it can:
① Reduce the distance for sperm to break through;
②Deeper insertion makes women more likely to have orgasms. Possibilities to try: normal position, bent position, back position, front seat position.
Warm Tips
Women with a strong desire to dominate and overconfidence, their eggs are better at accepting the Y chromosome in sperm due to high male hormones. Therefore, women who often give orders and have great power have a higher chance of conceiving a boy than ordinary women.
Meanwhile, new research shows that working in masculine professions such as engineering or accounting significantly increases a pregnant woman\’s chance of giving birth to a boy. Because women in masculine occupations tend to have \”systemic\” brains, they have higher levels of testosterone in their uterus during fertilization, thus increasing the possibility that the fetus will be male. Does an expectant mother want to give birth to a boy? Then find a masculine career.
A recent study by American scientists shows that married women with well-off families, high education levels, and good health are more likely to give birth to boys; while women from poor families and poor health are more likely to give birth to boys. It is easier to have a daughter.
This research is consistent with the principle of evolution. In many cases, women have stronger survival abilities, so women from poor families will give birth to girls with higher survival rates. And women from wealthy, healthy and strong families are more likely to have sons, so as to ensure that their genes and family can be passed down from generation to generation.
