At 12 weeks, determining a baby's gender via ultrasound can be inaccurate. The genitalia are not fully developed, making mistakes more common. Some studies suggest an accuracy rate of 75%, but it’s better to wait until the 18-20 week anatomy scan for more reliable results.

Questions and answers

  1. Can an ultrasound at 12 weeks reliably determine a baby's gender?

    The most reliable time to determine a baby's gender by ultrasound is during the 18-20 week anatomy scan.

  3. Why can a baby’s sex be mistaken during early ultrasounds?
