Calculator for calculating the expected date of delivery of boys and girls

Before the baby is born, for various reasons, mothers or family members are more concerned about the sex of the unborn baby. Usually, they will guess the sex of the fetus through some methods or phenomena, such as the traditional and ancient method of saying that the baby is sour and spicy, and the method of predicting the shape of the stomach. These are unscientific. Recently, there is a novel method to predict whether a mother is pregnant with a boy or a girl. I wonder if it will work. This is a calculator for calculating the estimated delivery date. Let's take a look together.

Calculation principle of expected date of delivery for boys and girls

Many people are curious, how does the pregnancy calculator calculate whether it is a boy or a girl? Like fortune telling? In fact, giving birth to a boy and a girl with a pregnancy calculator is actually adding up your age (lunar calendar) and the month of the expected date of delivery. If it is singular, it is a boy, and vice versa.

Are calculators accurate for boys and girls?

1. In fact, according to biological research, having a boy or a girl is determined by the sex chromosomes in the germ cells. It has nothing to do with the time of conception. The calculator for giving birth to boys and girls is said to be formed by calculation and deduction of Heluo number, Yijing number, Dayan number and calendar. Pregnant couples calculate the sex of the baby according to the calculator for giving birth to boys and girls. Although calculators for boys and girls are widely circulated on the Internet, there is no relevant literature about calculators for boys and girls, so there is no research source for their authenticity. Therefore, Mom.com thinks that we should not be too addicted, and believe that the calculators of boys and girls are accurate!

Maybe you understand the principle of determining sex as soon as you talk about it. Specifically, half of * * * has (22+X) and the other half has (22+Y). There is only one chromosome type in an egg, namely (22+X). X and Y in chromosomes are sex chromosomes, so they are called sex chromosomes. When * * * is combined with the egg (when the egg is fertilized), if * * with (22+X) chromosome is combined with the egg, the two will combine into (44+XX) and develop into a female fetus. If * * * with (22+Y) chromosome is combined with an egg, the two will combine into (44+XY) and develop into a male fetus.

Finally, Ma Wang's suggestion is that it has been decided whether to have a boy or a girl at the moment when fertilized eggs are combined. It is actually unscientific to calculate. If you want to know in advance whether to have a boy or a girl, you can go to the hospital for a B-ultrasound when the fetus is forming!
