When Do You Find Out the Gender of Twins?

In This Section

You’ve already found out that you’re expecting twins and that’s incredibly exciting news of its own. But now comes the follow-up question that doesn’t leave you in peace: What gender are my twins?

When do you find out the gender of twins depends on quite a few factors, such as are expecting fraternal twins or identical twin babies, and many more. We’re going to look at those factors, as well as, the different ways you can get a sneak peek into your babies’ gender.

Once you know the gender of your twins, you can start preparing for your new family members, but we’ll get to that in a little bit.

When Is Gender Determined?

The earliest you can find out the gender of your twins is when you’re 10 weeks pregnant with twins through blood tests, and your twins will also be tested for Down Syndrome. If you decide to have an ultrasound around the 12 to 13 weeks of your twin pregnancy, you will also find out what gender your babies will be. Many couples find out their baby’s gender at the fetal survey appointment, which is around 20 weeks.

And others decide to keep the gender reveal a secret and be surprised at birth. That way, you’re only letting your motherly intuition guide you. As much fun as this might sound, some parents might feel a bit intimidated by the unknown and might start stressing out about getting ready for the arrival of their twin babies.

How Can They Tell Gender from Blood Tests?

For the impatient parents, and also the concerned ones, any type of chromosomal testing will determine the gender of your twins as early as week 10 of your twin pregnancy. 

Noninvasive parietal testing (NIPT), or also called Cell-free fetal DNA testing gender reveal (cfDNA), is usually done to screen for Down Syndrome – something which is definitely worth getting checked for. As a bonus, you will also learn the gender of your twins, because the blood sample will include DNA from both babies. 

If your NIPT test indicates the presence of a Y chromosome, which is present in the XY chromosomes of males, you’re expecting at least one boy. Regardless, you will still need to wait for your ultrasound to give the final determination of two boys or boy/girl twins. If NIPT doesn’t show any Y chromosomes, it’s most likely that you’ll be having twin girls.

When Do You Find Out the Gender of Twins?

Ultrasounds are a must during twin pregnancies; because there are quite a few complications that might occur. But that shouldn’t worry you, because that’s what ultrasounds and other tests are for.

If you’re lucky you might even be able to find out the gender of your twins during your very first ultrasounds at around weeks 12 to 13. By lucky, we mean that your babies must be positioned in a way that is easy to read both of their genders. Oftentimes one of the babies might be blocking the view of the second one, but it’s worth giving it a try.

Nevertheless, if you wait a little bit longer ultin week 16 to 18 and are in the hands of a competent physician you will most likely find out the gender of both twins during your ultrasound.
