Breakfast habits

According to a British study, women who often eat breakfast cereals, foods high in calories and potassium are more likely to have a boy. Illustration.

A British study surveyed 740 pregnant women about what they ate before becoming pregnant. As a result, those who often ate cereals, foods rich in calories and potassium for breakfast were more likely to have a boy. In contrast, women who often skip breakfast are more likely to give birth to girls.

Age

Some studies have shown that sperm count in men decreases with age. The older the man, the higher his chances of having a girl. Similarly, as a woman ages, the amount of alkaline secretions in the uterus will gradually decrease due to the effects of the aging process, the chances of having a girl therefore also increase significantly. Therefore, older couples often have a higher rate of having a girl than younger couples.

According to the results of a British study, for every 5 years a couple increases, the chance of having a girl increases by 1%. Men aged 25-29 give birth to more boys than girls, while men over the age of 29 give birth to more girls than boys.

Quality of living environment

Scientists at the University of Chicago, USA conducted a study in which they examined medical record data based on factors such as environmental quality index, temperature … of 150 million Americans. for 8 years and 9 million Swedes over 30 years. The researchers found that certain pollutants, such as mercury pollution, near industrial plants can change the sex ratio by as much as 3 percent. For example, areas with higher mercury exposure tend to have more boys, while areas with higher soil lead levels have higher rates of girls.

“Love” pose

The X chromosome carries sperm that are larger in number and lighter than the Y chromosome. This also means that lighter sperm can meet the egg more quickly. This may be the reason why many people believe that certain sex positions can make X or Y “swim” to the egg faster.

According to Webmd, the traditional position (male on top, female below) makes it easier for you to have a girl, while the male position “attacking” from the back has a higher chance of giving birth to a boy.

Environment “little girl”

An alkaline environment helps increase the rate of boys because Y sperm are vulnerable in an acidic environment. Illustration.

According to the results of some studies, the vaginal environment can also partly affect the sex of the fetus. Specifically, an alkaline environment helps increase the rate of boys because Y sperm are vulnerable in an acidic environment. Therefore, an acidic environment will be more likely to have a girl.

Time to do “that”

Choosing the time when you ovulate to conceive is a widely used way to determine the sex of your baby. Accordingly, if you have intercourse near ovulation, you will have an easier time having a boy. And “in love” far from this time, the rate of having a daughter will be higher.

Smoke

Japanese and Danish researchers have found that couples who smoke before and after conception are less likely to have a boy. If the father smokes more than 20 cigarettes a day while the mother does not smoke, the probability of having a daughter is also much higher than that of a son. If you both smoke, your chances of having a boy are lower.
