Drink plenty of water before ultrasound to determine the sex of the fetus.

Introduction: Many pregnant couples will want to determine the baby's sex early. But basically, you need to wait until 12 weeks after pregnancy to clearly see the sex of the fetus in the womb. Ultrasound is the most commonly used test to determine gender. Drinking water before examination can increase the amount of amniotic fluid and ensure clear imaging.

1. When can we definitely judge the sex of the fetus? 1, the eleventh week of pregnancy, although the baby's sexual organs began to develop internally from the ninth week, even at 1 1 week, the appearance was still not obvious. So there may be errors in ultrasound imaging at this time, and there may be changes in the next few weeks.

2. In the twelfth week of pregnancy, the baby's external reproductive organs will begin to show obvious signs of gender. Theoretically, the baby's external genitalia can be clearly seen by ultrasound at this time, but it is still possible that the genitalia can't be seen because of the baby's position.

Ultrasound can detect the sex of a baby. 3. In the thirteenth week of pregnancy, the ultrasound imaging at this time is almost 100% accurate, so as long as the baby's posture is appropriate, you can clearly judge the baby's gender from the ultrasound photos.

Second, the key points to pay attention to before ultrasound scanning 1, it is best to arrange ultrasound photography after 12 weeks of pregnancy, because the baby's external genitalia has already appeared at this time. If you are pregnant with a big belly, you'd better wait another week, because the abdominal tissue may cover up the baby's image.

2. Drink plenty of water. If there is more amniotic fluid, the ultrasound imaging will be clearer. So you should start drinking plenty of water two weeks before the ultrasound scan, which can help the amount of liquid in the uterus.

3, let the baby have activities In order to capture the baby's image, you should let the baby keep active while scanning. You can drink a glass of orange juice or apple juice 30 minutes before the scan. It is said that this will make your baby more active in the womb.

Third, the commonly used method of detecting the baby's sex 1, amniocentesis detection amniocentesis is to insert a needle into the uterus to extract a little amniotic fluid, and then analyze it in the laboratory. This test allows the doctor to check whether the baby has hereditary diseases, and can also judge the sex of the baby.

2. villus sampling detection villus sampling is to take villus samples from the placenta for detection after pregnancy 10 weeks. This is also a test that pregnant women with high-risk pregnancy can choose, and it can also test the sex of the baby.

3, ultrasound examination In your regular prenatal examination, the doctor will conduct ultrasound examination from time to time to ensure the healthy growth of the baby, and at the same time, you can find abnormal growth or defects as soon as possible, so that you can also detect the baby's gender.
