gender pregnancy scan

Finding out you’re pregnant is a joyous and exciting time, particularly if you’ve been trying for a while. Understandably, you might be excited to discover the sex of the baby as soon as you can. The question is, how soon can you find out whether your little one is a boy or a girl?

Here, you’ll discover everything you need to know about learning the sex of your baby and how early it can be done.

When can baby’s sex be determined?

The majority of women discover the sex of their baby at their 20-week scan. However, it may be possible to determine baby’s sex before this. There are different types of pregnancy scans and tests available, and some may be able to tell you the sex as early as nine weeks.

However, you need to keep in mind that if you do opt to undergo an earlier scan or test, there is no guarantee the sex will be determined. It all depends upon baby’s position on the day of the test if you’re undergoing an ultrasound scan.

Another thing to keep in mind with an ultrasound scan, is that boys and girls can look very similar up until 14 weeks into the pregnancy. So, as difficult as it may be, it is worth waiting until your 20-week scan to get a more accurate idea of baby’s sex.

Can I find out during NIPT?

Non-Invasive Prenatal Testing (NIPT) is a simple blood test which is carried out to test for chromosomal abnormalities such as Down’s Syndrome. It can be done as early as 10 weeks into the pregnancy.

The test looks for male sex chromosomes, which can ultimately tell you if you’re having a baby boy or girl. The test is usually only offered to women with a high-risk pregnancy. However, you can choose to have the test even if you have a low-risk pregnancy by discussing it with your healthcare provider.

Be aware that this type of testing isn’t always 100% accurate. So, you’ll want to confirm the sex at your 20-week ultrasound scan.

What about NUB development?

There is a theory that all embryos have a small genital nub which is fixed during conception. Testosterone for baby boys starts to develop at seven weeks, which causes the nub to grow a scrotum and penis. In baby girls, the nub grows a clitoris and labia.

Genital nubs can be spotted on ultrasound scans. However, during your first scan it can be very difficult to find this nub. There is also a large chance it may be identified incorrectly. So, it is recommended you don’t rely upon this method to tell you the sex.

Overall, as excited as you may be to learn whether you’re having a boy or a girl, it is best to wait until your 16 to 20-week scan. This will provide you with the most accurate indicator of the sex of your baby. However, earlier scans can be useful to undergo anyway as they can tell you whether baby is developing at a healthy rate.
