What does an elderly person mean when they say that a pregnant person has a thin head and a thin tail? In rural China, there is a folk saying called 'pregnant men with thin heads and women with thin tails'. The meaning of this proverb is that if there is no change in the front of the belly of a pregnant woman, or if the woman herself is very thin, then she is likely to be pregnant with a boy; On the contrary, if a pregnant woman has a round belly but a thin waist, she may be pregnant with a girl.

This proverb is widely circulated in rural China, and many families use this method to predict the gender of the fetus. However, this method has not received scientific support and is not considered a reliable gender prediction method in modern medicine. Let's take a look at the scientific prediction methods for fetal gender.

Scientific prediction methods for fetal gender

1. Ultrasonic examination

Ultrasound examination is a very accurate method for predicting fetal gender. Usually, the first ultrasound examination can be performed during the 18th to 20th week of pregnancy, at which point the child's gender can be determined. Ultrasound examination can determine gender by observing the reproductive organs of the fetus, with an accuracy rate of over 99%.

2. Genetic analysis

Through genetic analysis, the gender of pregnant women and fetuses can be determined from blood samples. This method is usually performed in the early stages of pregnancy and has a very high accuracy.

3. Amniocentesis

Amniocentesis is a method of directly obtaining samples from the fetal body. By using this method, gender can be determined from fetal cells and certain genetic diseases can be excluded. However, since amniocentesis requires direct sampling from the fetal body, it poses certain risks and should only be used when necessary.

What does an elderly person mean when they say that a pregnant person has a thin head and a thin tail? In rural areas of China, the folk saying 'pregnant men with thin heads and women with thin tails' is widely circulated in many families, but this method has not received scientific support and is not considered a reliable gender prediction method in modern medicine. In fact, ultrasound examination, genetic analysis, and amniocentesis are three reliable methods for predicting fetal gender. If you want to know the specific situation of fetal gender, it is recommended that you consult professional doctors and medical institutions, and use scientific methods for prediction.
