Scientific Ways to Predict Baby's Gender

Scientific Ways

Will it be a girl? Or a boy? It’s a great fun to predict your unborn babies’ gender by using some popular ways such as by using the traditional Chinese baby gender chart, judging from the mother-to-be’s physical changes, interpreting pregnancy dreams and many other ways. However, they are all not scientific methods to predict. The prediction ultimately has about a 50 percent chance of coming true. If you want to make sure which gender you’re carrying, you are suggested to use some scientific ways. If you country allow to do gender prediction test, you could try to use one of the following ways under the doctor’s help.

Ultrasound Scan

Ultrasound is a kind of sound wave. So far, no report shows that it is adverse to the fetus. Therefore, it has been widely applied in the obstetrics and gynecology. Generally, the baby's gender can be clearly identified when the pregnancy exceeds 16 weeks. The detection method mainly observes the reproductive organ of the fetus, so it is directly related to the fetal position and the doctor's experience. When the ultrasound is used in identifying the baby's gender, the accuracy for baby boys is more than 95% but only about 85% for baby girls.


Amniocentesis is mainly for the purpose of diagnosing the chromosome or neuraltube defects of the fetus and it is often carried out between the 16th and 20th gestational week. Since it can detect the fetal chromosome, the baby's gender can be clearly identified. The accuracy is up to 99%, but it has the abortion rate of 1%. Therefore, amniocentesis is not recommended by the medical circle if it is only used for detecting the baby's gender.

Chorionic Villus Sampling

Also known as "chorionic sampling", it is often carried out between the 8th and 10th gestational week. Same with amniocentesis, it is mainly for the purpose of diagnosing whether the fetal chromosome is normal or not. However, some people also use it to identify the baby's gender and the accuracy is up to 98%.

Although chorionic villus sampling can identify the baby's gender as early as in the 10th gestational week or so, it may lead to the abortion (3% to 5%) or harm the fetus and make its hands or feet disabled. Therefore, it's better not to accept this sampling for the purpose of identifying the baby's gender.

Blood Test

The baby's gender can be identified by using the gene engineering technology to sample the mother's blood. It has no risk to the fetus and some test units claim that the reliability is up to 95%. As long as the pregnancy is over 8 weeks, the baby's gender can be identified by sampling the venous blood for test. However, the clinical data and evidence indicate that the error ratio is quite high. Therefore, it might not be a practical and reliable method.
