The Ramzi theory offers a highly accurate method to determine the sex of your baby at the very first ultrasound. However there are certain requirements for an ultrasound image to be optimal to apply the Ramzi Theory. Perhaps the question we get asked the most is “How early can I use the Ramzi theory?” So here’s a breakdown of the Ramzi theory at every stage of pregnancy and how it applies.

Ramzi Theory Week by Week

Before 6 weeks of pregnancy

Due to the lack of clinical studies surrounding this stage of pregnancy, we can’t speak as to the accuracy of Ramzi theory before 6 weeks of pregnancy. In our article “Ramzi Theory Explained” it shows the study done to more than 5,000 women that were between 6 and 9 weeks of pregnancy. However, because every baby develops differently, if an ultrasound is conducted at 5 weeks of pregnancy and a yolk sac is present, we believe Ramzi theory can still be applied accurately.

At 7 weeks of pregnancy

By the 8th week of pregnancy most women already know they are pregnant, but many are still waiting to have the first ultrasound. If you have had an ultrasound in your 7th week of pregnancy it is likely you were able to see the fetus with a heartbeat, and a disappearing yolk sac. This stage is optimal to apply to your ultrasound the Ramzi theory accurately.

At 9 weeks of pregnancy

Because the controlled study tested women that were between their 6th and 9th week of pregnancy, we don’t have written reports about the accuracy of Ramzi theory beyond 9 weeks. However ultrasound technicians can detect few changes in the development of the placenta in the 2 weeks after the controlled period. This means that it is very likely that Ramzi theory is accurate when applied at 9 weeks of pregnancy.

At 11 weeks of pregnancy

By this week the uterus continues to grow and Ramzi theory would only be accurate if there had been a previous follow up where the original placement of the placenta could be attested for and observe that at 11 weeks of pregnancy it is still on the same side as it originated. However this starts the period of nub – or genital tubercle- formation and depending on the baby’s development the Nub Theory can be used.

At 6 weeks of pregnancy

According to the study conducted, at 6 weeks pregnant a mother can have an ultrasound that clearly shows the beginning of placenta formation. At this stage it is even common to only see the yolk sac in an ultrasound. Using the Ramzi theory with only the yolk sac visible still provides the highest possibilities for accuracy.

At 8 weeks of pregnancy

This week of pregnancy is the most common to have a first ultrasound. This is also the last week for optimal Ramzi prediction accuracy. At 8 weeks of pregnancy you will most likely see a developed baby, perhaps even a little bit of brain developing, a heartbeat and possibly a yolk sac. Because placenta formation is starting at this stage an 8 week Ramzi theory prediction can be highly accurate.

At 10 weeks of pregnancy

This marks the ending period for Ramzi theory to be accurate. As your uterus expands to make room for your growing baby, the placenta also moves and thus voids the hypothesis made by Dr. Ramzi. If you have a 10 week ultrasound, it is still possible to get an accurate Ramzi theory prediction but as the 10th week progresses it is advised to start relying on other gender prediction methods.

At 12 weeks of pregnancy

The second trimester approaches and many pregnant mothers get a 12 week ultrasound to check nuchal translucency as well as the proper development of the vital organs. Even though Ramzi theory is not the most accurate for this stage, a 12 week ultrasound or beyond is optimal for an accurate Nub theory prediction. A this stage the genital tubercle is formed and will remain low if your baby is a little girl or start to raise if your baby is a little boy. Pleas note that using Ramzi theory 12 week ultrasound is not as reliable as in the earlier weeks.

As your baby grows ultrasounds are able to tell you more and more details about your new baby. Interestingly enough the opposite can be said about Ramzi theory accuracy, the earlier in your pregnancy the more accurate this theory can be.
