If you are wondering when you can find out the sex of a baby, the timing depends on the test used. Some prenatal blood tests can provide information relatively early in pregnancy, while ultrasound usually provides an assessment later. Test availability, accuracy, medical indication and local practice can vary.
When Can You Find Out?
Cell-free DNA screening can sometimes identify fetal sex from around 10 weeks of pregnancy. It is a screening test and is not the same as a diagnostic test. Ultrasound is commonly used around the middle of pregnancy and may show fetal sex when the baby’s position allows a clear view.
What About Diagnostic Tests?
Procedures such as chorionic villus sampling and amniocentesis can determine chromosomal information, including sex chromosomes, but they are invasive tests performed for specific medical reasons rather than simply to learn fetal sex.
Does the Timing Change?
Yes. Test availability, gestational age, fetal position, laboratory methods and clinical circumstances can affect when information is available.
Important Considerations
Fetal-sex information is different from predicting a baby’s sex from cravings, heart rate, belly shape or other popular signs. Those methods are not reliable ways to determine fetal sex.
Bottom Line
Ask your prenatal care team which testing options are appropriate for your pregnancy and when results are expected. Testing should be interpreted in the context of your overall prenatal care.
