The Ramzi Theory - predict your baby's gender from just 6 weeks

Section: Pregnancy
Ramzi Theory

Have you ever come across the Ramzi Theory? This gender predicting method has been said to be around 97% accurate when it comes to working out what sex your baby is before your 12 week scan. 

There are plenty of old wives' tales and theories around guessing your unborn baby's gender. A lot of mums-to-be love the Chinese Gender Predictor Tool, which originated from an ancient tomb near Beijing, more than 700 years ago.

Even Holly Willoughby has previously shared her (genius!) gender-guessing theory. 

One method you may have stumbled across is the Ramzi Theory, which revolves around your 2D scan photo between the 6 week to 9 week mark...  

What is the Ramzi Theory?

It's the theory that your baby's sex can be determined, based on the location of the placenta in the first ultrasound during the 6 week scan. This theory can be used for both an abdominal scan and a transvaginal scan (where a wand is inserted up the vagina). 

  • Placenta implanted on the left = girl
  • Placenta implanted on the right = boy

However, make sure you read your ultrasound correctly. If you have an abdominal ultrasound, the results are mirrored. If you have a transviginal scan, it should be the correct way and you'll get a clearer image. 

So if your placenta is on the right, that actually means it's on the left (suggesting a girl). If your placenta is on the left, that means it's actually on the right (suggesting a boy).

According to ObGyn.net, Dr. Saad Ramzi's method is using placenta /chorionic villi location as a marker for fetal gender detection at 6 weeks gestation and accoring to some studies, was found to be highly reliable. 

How to read your scan

It can be hard to read your scan, so it's always best to ask the experts when trying to identify which side your placenta is on. If you ask your ultrasound technician during your 6-8 week scan, they should be able to identify and let you know which side it is on. If you're unable to ask, look for the brighter area around the gestational sack. 

Your technician will also be able to help explain the orientation to make sure you're locating the placenta on the correct side, taking into account the mirror image. 

Is Ramzi Theory accurate?

It's claimed that using this theory to predict your baby's sex is over 97% accuracy. Woah!

One study by ObGyn.net found that this method correctly predicts the fetus gender in 97.2% of males and 97.5% of females early in the first trimester. And it might be helpful to use as a genetic soft marker in relation with fetal pyelectasis.

Despite the bold claims, gender prediction theories are only supposed to be a bit of fun. Don't deck out the nursery just yet!

When is best to use Ramzi Theory?

It's best to determine at your 6-8 week scan. For 12 weeks plus, you're better off trying the nub theory. 

You can request to find out your baby's sex during your mid-pregnancy ultrasound, which is technically done between 16-20 weeks. 

Ramzi theory FAQ's 

Does the Ramzi theory work for twins? 

There have been very little studies done with twins and predicting their gender using the Ramzi theory, so it's harder to predict in the early stages whether you're having two boys, two girls or one of each. Often with twins, there will be two placentas so you have to look out for the placing of both placentas rather than just one. 

Does it matter which ovary I ovulated from? 

No. An egg can be released from the right ovary and plant on the left and vice verser so this doesn't effect the side your placenta appears.
