Gender Scans | Sexing your Baby

If you chose to find out the sex of your baby, you are most likely going to have a ultrasound from a company specializing in early gender scans.

The Original Window to the Womb specialize in gender scans and has an excellent reputation and accuracy in this field .The earliest time for the ultrasound to be performed is 16 wks. The accuracy of the report will depend on many factors, including the age of the baby, the equipment used, the Sonographers, and the position of baby. However, there are certain signs in boy and girl ultrasound pictures that the Sonographers use to determine the gender of your baby.

One sign that mothers think automatically indicates a girl, for example, is the "Absence of a Penis = Girl" theory. This theory states that if the ultrasound Sonographer fails to find a penis the baby is automatically a girl. You will see below there is more to a girl ultrasound picture than the absence of a penis. In fact, particularly early on in pregnancy, a clitoris and a penis are roughly the same size and shape. A good and reliable ultrasound studio would not perform a gender scan before 16 weeks.

Three white lines (Girl - Gender Scan)

When doing an ultrasound to determine the sex of your baby, an ultrasound sonographer will actually look for girl genitalia—labia and clitoris. When looking up and under baby’s bottom, with legs wide open you will see clearly defined three white lines.

Obvious sticky out bits (Boy - Gender Scan)

When the ultrasound sonographer is looking for a boy, they are looking for obvious sticky out bits. This is where you can see the tip of the penis peeking between the legs. This may be harder to see with some babies, which is why there are multiple signs to look for during an ultrasound. The gestational age and position of the baby play a part in what can be seen. This obviously makes identifying a baby boy much easier.

Mistakes can happen

Ultrasound can never be 100% accurate, and baby’s gender can be easily misdiagnosed if baby is sexed before 16 weeks, as like all other organs it takes time to develop.

Gender Scan Mistakes

Do you worry about ultrasound gender mistakes?

Too Early

The best time to determine the sex of your baby is between 16 to 20 weeks. An ultrasound done before this is not reliable, as baby’s sex is not fully mature.

Not all ultrasound machines give good clear imaging. In fact, some ultrasound machines are simply very old and may not give the best views.

Some babies are simply shy and refuse to move. If that happens, the determination of babies sex may be made on poor images from a positioning point of view. It is also harder to tell the sex of the baby if the baby is sat upright, legs and feet are tucked under their bottoms or their legs are crossed.


Here at The Original Window to the Womb all our Sonographers are highly trained in gender determination and will continue to check baby’s sex throughout your scan.

Maternal Weight

It's a simple fact that if you are heavier, ultrasound image quality is less clear. This can cause difficulty in scanning. Combined with other factors and it may be really difficult to tell you the sex of your baby.
