How early you can detect the sex of your baby depends on a variety of factors. The most important factor, perhaps, is the particular method that you are going to use to detect the sex of your baby. The various methods of detecting the sex of your baby will not only vary as far as when they can be used, but they can also vary greatly in terms of how accurate they actually are.
The most accurate sorts of testing that can be done to detect the sex of your baby is testing that uses amniocentesis or chorionic villus sampling (CVS for short). An amniocentesis or CVS is more likely to be performed for some other purpose. Once the test is done, however, the genetic material can be analyzed to detect the sex of your baby. A CVS would typically take place between the 10th week and the 13th week of pregnancy, while an amniocentesis would usually take place between the 14th and the 20th week of pregnancy.

Beyond these tests, there are other ways to detect the sex of your baby. There are blood tests available for purchase that purport to be able to detect the sex of your baby. These tests are thought to work as early as the 6th week of pregnancy. In addition, the manufacturers of these tests typically offer a refund if they are wrong. However, the accuracy of these tests has not been adequately studied.

An ultrasound is perhaps the most common way to detect the sex of your baby. With an ultrasound, you can probably not detect the sex of yore baby until sometime between week 16 and week 20 of pregnancy. Having said that, there are a great many factors that go into how early you can detect the sex of your baby using an ultrasound. Everything from gestational age to the thickness of the mother’s abdominal wall can affect the amount of time that this process will take. An ultrasound is, after the 20th week of pregnancy, generally more than 90% accurate at being able to tell a baby’s sex.
