Can You Predict Your Baby’s Sex?

Are you wondering about the sex of your baby? There are lots of theories that profess to predict baby’s sex in the womb, but can you really trust anything other than science? Read on to find out.


Ultrasound Scan

If you’re looking for a way to tell the sex of your baby, the ultrasound scan is a great shout, but you’ll have to wait until you’re 20 weeks’ pregnant. For more advice on what to expect from your anomaly scan, click here.

Don’t forget foetal position can often obstruct the view of your baby, and technicians do sometimes make mistakes. They say accuracy of an ultra sound scan to predict the sex of your baby is around 97-99% in most pregnancies.

Harmony Test

Is a non-invasive prenatal test and is the most accurate way of identifying sex as well as other risks, such as down syndrome. The test can be offered from the 10th week of pregnancy.  This is done by blood test and scan.


Pulse diagnosis has been used in traditional Chinese medicine for over 2,000 years. A good acupuncturist may be able to predict baby’s sex as early as cycle week 5.

The Ramsay Theory

Early gender prediction method. He studies the relationship between the placenta location and gender. Most accurate between the 6 & 8th week of pregnancy.

Other theories include:

Nub Theory

From around 11 weeks gestation, both boys and girls have a swollen area of genitals that looks like a nub. Some thing that by looking at your baby’s side profile you could hazard a guess…

Skull Theory

According to the theory, the shape and size of a baby’s skull can determine whether you’ll have a boy or a girl. The general belief is that baby boys have bigger and blockier skulls than girls. More specifically, boys have a defined brow ridge, square chin, and more angled jaws. Plus a boy’s skull tends to have more prominent cheekbones. In contrast to boys, baby girls have rounder chins with a wider angle to their jaws. Additionally, their foreheads are less sloping with smaller brow ridges.

Old Wives Tale

Wedding ring on a string

Tie your wedding ring to a long piece of string, mother lies flat with the bump towards the sky. Partner/friend to dangle the ring a few inches above your tummy. Back and forth means it’s a boy, and circular means it’s a girl.

How you carry the bump

If it is high it is a girl, and low it’s a boy.

Party weight gain. If your partner gains weight you are having a boy and if your partner stays the same it’s a girl.

Spontaneous pregnancy acne 

If you do have acne you are having a girl, clear skin means it’s a boy.

Pregnancy craving

If you want something salty or protein-rich foods- it’s a boy, and sweet, fruity– it’s a girl.
