If you have a baby at home, the gender of the baby is a big issue! Families of pregnant women, especially families with elderly people who are concerned about the gender of the fetus, want to know whether the little prince or the little princess will grow in the mother\’s belly. Today I will introduce to you an exclusive secret recipe – reduce the biparietal diameter by reducing the femur length for gender identification! I heard that this method can effectively determine the gender of the fetus starting at 24 weeks of pregnancy! Come and see if this artifact is reliable!
You must be wondering, what is biparietal diameter minus femoral length? In fact, it is very simple, just by measuring the size of the fetal head and the length of the femur of the legs to determine whether the baby is male or female. According to professional data analysis, starting from 24 weeks of pregnancy, if the biparietal diameter minus femoral length is more than 1.7, then the baby is likely to be a boy. If the father is tall and strong, the double strands will basically be greater than 2.1 after 30 weeks in the third trimester. These data are not produced by me! 
However, please be careful! While this method sounds amazing, we need scientific validation and research to determine if it is truly reliable. After all, we can’t just rely on one method to determine the gender of a baby, right?
Question 1: Is this method accurate and reliable? We need more scientific validation and research results to know for sure.
Question 2: Is the scope of application broad? Because everyone\’s body shape, race, region and other factors are different, whether this method is suitable for all pregnant women needs further evaluation.
Question 3: How credible is the science? We need to know more about the scientific basis, research results and professional opinions of this method to ensure its credibility.
How to calculate gender by subtracting biparietal diameter from femoral length?
Biparietal diameter refers to the length of the widest part between the left and right parietal bones of the fetus\’ head, while femoral length refers to the length of the fetus\’s thigh bone. Generally, these two values are mainly used to observe the intrauterine development of the fetus and determine whether natural delivery is possible.
1. The calculated result is greater than 21mm: If the femur length is subtracted from the biparietal diameter and the result is greater than 21mm, it means that the pregnant woman is likely to have a boy;
2. The calculated result is less than 21mm: If the femur length is subtracted from the biparietal diameter and the result is less than 21mm, it means that the pregnant woman is likely to have a girl.
To sum up, the target users are those who pay attention to tireFamilies of pregnant women who want to determine the sex of their baby by subtracting the biparietal diameter from the femoral length. However, due to issues such as accuracy, scope of application, and scientific credibility, users should be cautious and seek professional advice when necessary. After all, before naming your baby, it’s best to confirm whether he/she is a prince or a princess!
