It can be a fun way to make an informed guess about your baby’s gender

Quick notes:

  • The Ramzi method correctly predicts the fetus’ gender in more than 95 percent of babies

  • It often works as early as the first trimester.

  • Parents usually must wait until about 18-20 weeks into a pregnancy to get an accurate gender.

Parents usually have to wait until about 18-20 weeks into a pregnancy to find out if they’re expecting a boy or a girl. The reveal almost always happens during a routine ultrasound at their caregiver’s office. However, more recently, many parents are turning to an alternative approach to predicting their baby’s gender as early as eight weeks of pregnancy. This alternate approach, known as Ramzi Theory or the Ramzi Method, is gaining a lot of popularity among moms to be.

What is the Ramzi theory?

The Ramzi method was developed by Dr. Saam Ramzi Ismail and claims that you can predict a baby’s sex as early as six weeks into your pregnancy. It does this by using a specialized ultrasound to determine where the placenta is formed.  According to the Ramzi method, placentas that are on the right side are male and on the left side are female. That’s all there is to it.

According to, the Ramzi method is said to correctly predict the fetus’ gender in 97.2% of the males and 97.5% of the females early in the first trimester. This result is based on an extensive and controlled study of over 5,000 pregnant women.

It’s worth remembering that there are some scenarios where the theory works better than others. For example, it is most accurate early in pregnancy because as the uterus expands the placenta moves, diminishing the chances of an accurate prediction.

When the Ramzi theory doesn’t work

There are very specific times when the Ramzi theory isn’t as likely to prove accurate. One example is when a pregnant woman is carrying multiples. In these cases, it can be tougher to determine the position of the placenta.

The Ramzi method is also less likely to work in pregnancies that have developed past nine weeks. That’s because by that point it is impossible to tell where the placenta originally formed.


After using the theory, some parents are surprised to find a different result when they go for their ultrasound at 18 to 20 weeks. They might question the theory’s accuracy at that point. While the theory isn’t foolproof, there’s a remote chance that it’s the traditional ultrasound — not the Ramzi method –that’s inaccurate. Even during a traditional ultrasound, it can be hard to get a good look at baby. Sometimes positioning just isn’t as good as the ultrasound tech believes it to be.

Proof against the Ramzi theory

While anecdotal evidence and some formal trials support the success of Ramzi theory, there isn’t a lot of other proven evidence that shows it works. At the same time, there is a great deal of evidence against denying its efficacy.

Keep in mind, though, that while it’s far from proven there doesn’t appear to be any real harm in trying it out. A parent who wants to give it a shot can just see what happens. At the very least, it is an intriguing experience and if there is anything concerning, more standard follow-up tests can help parents understand what’s going on.
