I believe many expectant parents are curious about the gender of their upcoming baby. Although science is very advanced now, going to the hospital for an ultrasound can easily handle it. Unfortunately, there are regulations in the country that prohibit doctors from disclosing the gender of infants at will. Don't lose heart! Now let me teach you several small methods for predicting the birth of boys and girls. Expectant mothers can come and test them!
1. Calculating formulas to test male and female students
Formula 1: When you are pregnant, your virtual age plus the month of pregnancy plus 19 equals odd numbers for boys and even numbers for girls.
Virtual age=(last menstrual period year month day - birthday year month day) (Gregorian calendar), take the year+1 from the results
Example: Birthday 1980.12.5, last menstrual period on July 29, 2010
Calculation of virtual age:
Subtracting the two results in a one year age of 29 years, July 24 days (accurate to the number of days), and a virtual age of 29 years+1=30 years. Using the formula 30+7+19, even numbers are equal to daughters.
Formula 2: Multiplying the lunar month of pregnancy by double+the lunar birthday month of the pregnant woman - the virtual age at the time of pregnancy+19=, the result is that the number ending in single is a boy, and the number ending in double is a girl.
Example: The month of pregnancy is in June according to the lunar calendar, the month of the pregnant woman's birthday is in July according to the lunar calendar, and the virtual age is 29 years old. The calculation method for giving birth to a boy or a girl is 6x6+7-29+19=33, and the resulting number ends in a single digit, indicating that it is a boy.
Formula 3: The sum of the father's age at the time of pregnancy, the mother's age, and the number of months of pregnancy (all in real years), divided by 3, yields an integer. The odd number represents a boy, while the even or zero number represents a girl.
Example: The father is 30 years old and the mother is 27 years old. She became pregnant in June. The calculation method for male and female births is (30+27+6)/3=21. The result with a single digit indicates that it is a boy.
Formula 4:49+Subtract the mother's virtual age from the lunar month when the mother is pregnant+19=(), resulting in a number ending in a single for boys and a double for girls.
Example: When the mother is pregnant, her virtual age is 28 years old, and the lunar month of pregnancy is August. The calculation method for giving birth to a boy and a girl is 49+8-28+19=48, and the result ends in double, indicating the birth of a girl.
2. Checking the gestational sac to determine the birth of male and female
The gestational sac for giving birth to a son is elliptical, while for giving birth to a daughter it is circular (according to statistics, this is the most accurate!).
3. Listen to fetal heart rate test for male and female students
After eight months of pregnancy (when the child is no longer in the womb), when listening to the fetal heart rate, if it is on the left side, it is a male baby, and on the right side, it is a female baby.
4. Observing the placenta to identify male and female births
There are more girls born on the wall before pregnancy and more boys born on the wall after pregnancy, with an accuracy rate of about 80%.
There are many folk methods for predicting the birth of boys and girls, but are they accurate? The moment when the melon ripens and the buds fall is the time to verify the answer!
