NHS Video: Can we find out the sex of our baby?
The NHS help you understand what need to know about finding out the sex of your baby
You can normally ask the sonographer during your second routine ultrasound scan (sonogram) if you want to find out the sex of your baby.
This scan is done when you are around 18 to 21 weeks pregnant. It is not an exact science and the sonographer will not be able to be 100% certain about gender.
In this NHS video, midwives explain what happens at a scan
