I am one mother-to-be who eagerly awaits her 20 week ultrasound. I just have to know if I’m having a girl or a boy. After all, there is so much planning to do.
But how accurate are gender prediction tests?
Should you go out and buy all pink or blue based on a test? Does it make a difference if the test is an old wives tale, pregnancy folklore, or a scientific test?
You might be surprised to learn how accurate, or inaccurate, these tests really are.
Girl or Boy? The Accuracy of Gender Prediction Tests
Popular Gender Prediction Tests
You can take gender prediction tests online. These tests are based on answers you give about your conception, pregnancy symptoms, and even your spouse.
Online tests are fun, but I wouldn’t bet my paycheck on them, since there is no scientific proof behind them.
Three of the more popular gender prediction tests are:
Many of these tests have a 50 percent accuracy rate, which isn’t exactly definitive. However, while writing this article, I took each of these tests and to my surprise they were remarkably accurate. All three tests said that we are having a baby girl, which we are, according to our 20 week ultrasound.
Scientific Gender Prediction Tests
If you really want to know if you are having a girl or a boy, you’ll need to get a more accurate gender prediction test. These tests include a scientific ultrasound (after 20 weeks gestation), amniocentesis, or Chorionic Villus Sampling (CVS).
Many doctors will automatically schedule a mid-pregnancy ultrasound after 20 weeks gestation to evaluate the growth of your baby, and it may be possible to determine if you are having a girl or boy at this time. Keep in mind, several factors including the position of the fetus will influence the accuracy of the gender prediction. Predicting gender through ultrasound after 20 weeks gestation can be up to 90 percent accurate.
Most doctors will not perform the invasive amniocentesis or CVS tests just for the purpose of baby gender prediction, since these tests have a higher risk of fetal loss than the non-invasive ultrasound. Both of these medical procedures are used in prenatal diagnosis of chromosomal abnormalities and fetal infections in high risk pregnancies. If you have an at-risk pregnancy and require an amniocentesis or CVS test, genetic testing results through these two tests can be up to 99.1 percent accurate.
We never had an amniocentesis or CVS test with my first two pregnancies, but I felt 100 percent confident in the gender prediction of our three boys. To be honest, our boys were not shy. I hate to admit with this pregnancy, I’m not 100 percent confident that the prediction is accurate, even though the ultrasound technician was confident.
Maybe after three boys I just can’t imagine having a little girl, or maybe my mommy instinct is telling me something. What ever it is, we’ll have to wait until delivery day to know for sure if we’re having a girl or not.
