30 weeks pregnant boy fetus diagram

Nowadays, it doesn’t matter whether you have a boy or a girl. Many women want to know whether they are giving birth to a boy or a girl after they become pregnant. It is not because of traditional inertial thinking, but simply out of curiosity. Since they cannot distinguish through examinations, they hope to understand from symptoms. So what are the symptoms of having a boy at 30 weeks of pregnancy?

1. Becoming ugly during pregnancy means the baby is a boy: After pregnancy, the human body will be affected by growth hormone, which will cause changes, and the pregnant woman will also show some symptoms. If you are pregnant with a boy, the proportion of androgen will increase. At this time, the pregnant woman's skin will become very bad under the action of androgen. Through this method, you can distinguish the boy or girl of the baby.

2. A long and thin pregnancy line indicates a boy: When the pregnancy reaches a certain period, a line will appear on the pregnant woman's abdomen, which will disappear after giving birth. This line is what we often call the pregnancy line, and the line is different for different genders. If the mother's pregnancy line is thin and long, and is separated from the left and right sides of the belly button, then it means that the mother is pregnant with a boy.

3. A protruding belly button indicates a boy: In addition to the above two characteristics, the mother’s belly button is also an appearance standard for identifying the gender of the fetus. If in the late stages of pregnancy, mothers find that their belly buttons are protruding, it means they are pregnant with a boy.

Although it is possible to see it in this way, there should not be a big psychological gap. Because everyone's situation is different, the results shown may sometimes be different, and we cannot be completely confident.

How to identify the sex of the fetus

1. Ultrasound scanner: Ultrasound is a kind of sound wave frequency. Reports so far show that it has no adverse effects on the fetus, so it is widely used in obstetrics and gynecology. When using ultrasound to confirm the sex of a fetus, the accuracy for a boy is over 95%, while the reliability for a girl is only around 85%.

2. Amniocentesis: Amniocentesis is mainly used to confirm whether the fetus has defects in sex chromosomes or neural tube defects, and is usually performed between 16 and 20 weeks of pregnancy. Since the sex chromosomes of the fetus can be known, the gender of the fetus can also be known. The accuracy is 99%, but there is a 1% chance of miscarriage.

3. Villus sampling: also known as "hairy sampling", is usually performed at 8 to 10 weeks of pregnancy. The main purpose is the same as amniocentesis, which is to confirm whether the fetus's sex chromosomes are normal, but many people also use it to confirm the sex of the fetus. The accuracy reaches 98%.
