If you’re a soon-to-be parent, you’ve probably heard of an ultrasound and are eager to get one done. Ultrasound is a safe way to check that your baby is growing and developing properly, and it can reveal important information about your pregnancy, such as the gender of your child.
The earliest test for finding out your baby’s gender is called Nipt, which can be done at around nine weeks. However, some patients prefer a gender determination scan and this can be carried out from 16 weeks onwards depending on the individual.

Gender Scan: What it is and How It Works
An ultrasound, or sonogram, uses high-frequency sound waves to create an image of your baby on the screen Early pregnancy scans Belfast. A transducer wand sends pings of energy through your abdomen or vaginal cavity and then picks up the sound waves when they bounce back off your baby’s tissues and fluids.
Your sonographer will also be able to determine your baby’s gender by examining its genitalia, which are the organs that make up the testes and scrotum. Male genitalia usually start to appear by about 18 weeks, and female genitalia aren’t visible until about 21 weeks.
A Gender Scan Doesn’t Always Give an Easily Accurate Answer
Although most ultrasounds are done between 18 and 22 weeks, the earliest ones that will be able to accurately determine your baby’s gender are done between weeks 11 and 14 of pregnancy. That’s when your sonographer can tell you whether it’s a boy or a girl, but the accuracy of the results depends on the clarity of the images and your baby’s positioning in your uterus.
