Biparietal diameter at 17 weeks of pregnancy to determine the gender

Nowadays, people's awareness of having a boy or a girl may not be as high as it was in ancient times, but it is inevitable that some people still worry about this issue. I hope to identify the gender of my child through some methods, but there are still many different methods, it just depends on whether the mothers are careful. The following editor will show you whether the biparietal diameter of the 17-week fetus is accurate in determining the gender of the fetus.

Is it accurate to measure the gender of the fetus by the biparietal diameter at 17 weeks?

1. Fetal biparietal diameter is also known as BPD, the biparietal diameter of the fetal head. It refers to the length of the widest part between the upper and lower sides of the fetal head, also known as the "great transverse diameter of the head". Doctors often use it to observe the growth and development of children, determine whether there is cephalopelvic disproportion, and complete the delivery of pregnant women.

2. At full term, the biparietal diameter of the fetus should be 9.3 cm or above. According to general regularity, after the fifth month of pregnancy, it is basically consistent with the pregnancy phase. In other words, the BPD is about 7.0 cm at the 28th week of pregnancy (7th month), about 8.0 cm at the 32nd week of pregnancy (8th month), and so on. After the eighth month of pregnancy, an average increase of about 0.2 cm per week is normal. When the due date cannot be determined based on CRL in the early stage, BPD is usually used for prediction; in the middle and late stages, when determining the baby's weight, it is usually necessary to accurately measure this data.

3. Experts remind: It is not scientific to use the biparietal diameter of the fetus to determine whether the fetus is male or female. However, the fetal biparietal diameter is used to calculate the weight of the fetus. The formula is: baby weight = fetal biparietal diameter * 900-5200 (g).

Fetal femur length (FL) is a common indicator used by doctors to observe the baby's development when they use B-ultrasound (or B-ultrasound) to perform prenatal check-ups on pregnant women.

3. The femur and humerus are both typical long tubular bones in the body, both of which can be divided into two ends. The femur is the largest long bone in the body, which refers to the thigh bone; the humerus is located in the arm, also known as the upper arm bone. So to put it simply, the femur length refers to the length of the thigh bone, and the humerus length refers to the length of the upper arm bone.

4. Fetal femur length and humerus length are both fetal microbial indicators that predict fetal body quality. However, fetal humerus length is better than femoral length in predicting fetal body mass.

The above is the editor’s summary of relevant information on whether the biparietal diameter of a 17-week fetus is accurate in measuring the gender of the fetus. I believe it will be of great help to everyone. When you roughly determine the gender of your child through this method, you should also note that this thing has not been clinically verified and has no validity. The editor hopes that mothers will treat everyone equally, not be sexist, and respect life.
