You can typically find out your baby's gender between 16 and 22 weeks of pregnancy through an ultrasound scan, with many doctors scheduling this around 18 to 20 weeks. Ultrasound gender determination is generally accurate starting at 16 weeks because the baby's anatomy is developed enough to reveal gender, although earlier attempts (as early as 11 to 14 weeks) are possible but less reliable
. Additionally, noninvasive prenatal testing (NIPT), a blood test analyzing fetal DNA from the placenta, can determine gender as early as 9 to 10 weeks with high accuracy, though it is a screening rather than a diagnostic test
. More invasive diagnostic tests like chorionic villus sampling (CVS) and amniocentesis can also reveal gender, with CVS typically done between 10 to 12 weeks and amniocentesis around 16 to 20 weeks
. Summary:
- Earliest reliable gender determination by ultrasound: ~16 weeks (sometimes earlier but less accurate)
- Common ultrasound timing for gender reveal: 18–22 weeks
- Earliest gender determination by NIPT blood test: ~9–10 weeks
- CVS test timing: 10–12 weeks
- Amniocentesis timing: 16–20 weeks
Most parents find out the baby's gender during the mid-pregnancy anatomy scan around 18 to 20 weeks, but earlier options exist depending on the method chosen and medical advice
