There are two things about ultrasound: basically boys? How to determine fetal gender through ultrasound examination! This is one of the most concerning issues for many expectant mothers during pregnancy. In this article, we will explore the methods that can determine fetal gender in ultrasound examination, and introduce the accuracy and reliability of ultrasound examination for fetal gender.

1、 How to determine fetal gender through ultrasound examination?

B-ultrasound examination is a non-invasive examination method that can help doctors observe the development of the fetus in the uterus and the condition of various parts of the body, but it is not specifically used to determine the gender of the fetus.

However, during the ultrasound examination process, doctors may observe some indicators that can help determine the gender of the fetus, such as:

1. Genitalia: At 22-26 weeks of gestation, ultrasound examination can observe the fetal genitalia. If you see a penis, it is likely a boy; If you see the vagina, it is likely a girl.

2. Urinary tract: The urinary tract of male fetuses is thicker than that of female fetuses, so doctors may observe the size and shape of the bladder or prostate to infer the gender of the fetus.

2、 What is the accuracy and reliability of ultrasound examination for fetal gender?

Although B-ultrasound examination can be used to infer fetal gender, it is not 100% accurate and reliable. The main reasons are as follows:

1. Fetal position: If the fetal position is incorrect, it may affect the doctor's observation of the fetal genitalia, leading to misjudgment of the fetal gender.

2. Different gestational weeks: At different gestational weeks, the development of the fetus's genitalia also varies, making it more difficult to determine the gender of the fetus at certain times.

3. Quality of B-ultrasound instruments: Different B-ultrasound instruments may have different resolutions and detection capabilities, and errors may occur when determining the gender of the fetus.

3、 Other methods for determining fetal gender

In addition to ultrasound examination, there are other methods that can help expectant mothers determine the gender of the fetus, such as:

1. With the help of genetics: Men only carry the Y chromosome, while women carry two X chromosomes. Therefore, fetal sex can be determined through genetic methods.

2. Blood testing: By detecting the presence of specific fetal DNA fragments in the blood of expectant mothers, the gender of the fetus can be inferred.

No matter which method is chosen, it needs to be carried out under the guidance of a professional doctor.
