Can I find out the sex of my baby?
An ultrasound scan (sonogram) transmits high-frequency sound waves through your uterus. The sound waves bounce off your baby and are translated by a computer into an image on a screen, showing your baby’s position and movements.
Your first scan is carried out at around 10-14 weeks. This will give you the first glimpse of your baby. The main purpose of this scan is to check that your baby is growing and developing normally.
Finding out your baby’s sex
The second scan is carried out at around 18-22 weeks and, if you want to know, it can usually determine the sex of your baby.
If you want to know the sex of your baby, you should ask your sonographer (the person who carries out the scan). It is best to ask them at the beginning of the scan so that they are aware that they need to check.
It is important to be aware that it is not possible for your sonographer to be 100% certain about your baby’s sex. For example, if your baby is lying in an awkward position, it may be difficult, or impossible, to tell whether your baby is male or female.
Some hospitals have a policy of not telling patients the sex of their baby. If your hospital does not routinely inform parents about their baby’s sex, you may be able to pay privately for a scan to find out. Speak to your sonographer, or midwife, to find out more.
