The Ramzi Theory

"It's the question in most mom's minds from the moment they see those two lines,"
- When will I know the gender?

What is the Ramzi Theory?

Now widely known because of his early gender prediction method, Dr. Ramzi directed multiple studies in which the relationship between placenta location and gender was the focus. In the controlled group studies, he discovered that he could determine male fetuses with 97.5% accuracy and female fetuses with 97.2%.

How accurate is Ramzy Theory?

By tracking the chorionic villi, also known as the future placenta, he gave the world a tool to very accurately reveal the gender of a baby at just 5 weeks of gestation. Although Dr. Ramzi’s theory isn’t 100% accurate, and there are multiple instances where the placenta is in a tricky spot, we believe a theory that is up to 97.5% accurate is a great foundation for a gender prediction

The Ramzi Theory

Why do I need professionals?

Because you can't believe everything you read online! There are several crucial aspects of this gender prediction based on placental positionthat need an expert eye. Detecting areas of growth and knowing when an images is mirrored are two of the most important ones. Do you know when to flip? This seems to be a hot topic when it comes to Ramzi theory. The general rule of thumb seems to be that if it is an abdominal ultrasound it will be a mirrored image, but if it is taken internally it is true to side, and although that might be the case for some images, we do not believe this is a one-size-fits-all solution. Baby Gender Pros believes that each scan should be looked at individually and look for markers. We have an extensive background in early gender prediction and are dedicated to providing new moms-to-be with the best experience possible.

What else should I know about Ramzi Method?

There is plenty to learn about this theory! Perhaps one of the most important factors to obtain a correct prediction is the gestational age of when the image was taken. Ramzi method is most accurate between the 6th and 8th week of pregnancy. Although placenta placement can be located at any point in pregnancy, it is most accurate early on because as the uterus expands the placenta moves, diminishing the chances of an accurate prediction.
In addition, sometimes the images are too zoomed out for the chorionic area to be visible, or the technician might have the brightness too high for us to see properly. The scanning plane of the ultrasound is also important. A transverse scanning plane is necessary for an accurate Ramzi method prediction. There are two other scanning planes, sagital (as if you were looking at someone from their side), and coronal (as if you were seeing someone face to face), but transvaginal ultrasound is the only place that shows you the body as if seen from above and good for gender determination.

Will it be a boy or a girl? This is probably the most exciting question pregnant moms have the moment they find out they are pregnant. Ramzi theory gender predictions are a great way to gain some insight into this matter from as early as your 6 week ultrasound. But is one week more accurate then the next? Let's see what the experts have to say.

5 week ultrasound

The accuracy on Ramzi theory at less than 6 weeks of pregnancy has not yet been studied. If you read our article on the Ramzi theory, you can find that the clinical study where the Ramzi theory was developed starting at just 6 weeks along. However, this is not to say that chorionic villi cannot be detected, say at 5 weeks and 4 days. If you have an ultrasound right before the 6 week mark, it is very possible that Ramzi theory accuracy will be the same as it is at 6 weeks.

6 week ultrasound

The official study consisted of over 5,000 expectant mothers that were between the 6th and 8th week of pregnancy. This makes a 6 week ultrasound a great candidate for an accurate gender prediction. Please note that being able to see the full gestational sac is very important for an accurate gender prediction. Ramzi theory 6 week ultrasound

7 week ultrasound

At this early stage in pregnancy, many women have already taken a pregnancy test but are still waiting for their first ultrasound. However, if an early ultrasound has been done, Ramzi theory at 7 weeks of pregnancy is accurate, and a mother will likely be able to see a yolk sac as well as the growing baby.

8 week ultrasound

The 8th week of pregnancy is when most women go in for their first pregnancy visit and have their first ultrasound! At this age, it should be easy to detect a heartbeat as well as possibly distinguish the head and rump of the baby. Ramzi theory accuracy is at its peak during the 8th week.

9 week ultrasound

Due to the controlled study only looking at women from 6-9weeks of pregnancy, anything after that is "unknown," however, we do know that every pregnancy is different and that every baby develops at a different speed. This means that the development of a baby at 9 weeks and 3 days might be the same as someone else's at 8 weeks and 6 days. We believe Ramzi theories are extremely accurate at 9 weeks of pregnancy.

10 week ultrasound

As previously stated, there is no evidence of the accuracy of the Ramzi theory at 10 weeks of pregnancy. At this stage, the yolk sac may no longer be visible, but you can still easily see which side the placenta is developing on. We believe 10 weeks is the last stage that the Ramzi theory maintains a great deal of accuracy.

11 week ultrasound

Nearing the second trimester, this week of pregnancy is able to show us good skull structure and the beginnings of a genital tubercle. This means that, although the accuracy of the Ramzi theory at 11 weeks is not high, we are able to combine it with other gender prediction methods like nub and skull.

12 week ultrasound gender

12 week ultrasound

As the uterus grows to fit the growing baby, the side on which the placenta started developing may no longer be clear. However, a 12 week ultrasound is the start of high accuracy for a nub prediction! Learn more about this theory that can predict the gender of your baby 99% at only 12 weeks.

Right the first time!

Hello! I did the ramzi theory and your team was right! I sent in my skull and nub 12 week scan while waiting for the Panorama blood work and received that result before your prediction. It’s a boy!

 by Teeyarh

Ramzi predicted at just 9weeks a boy, I instantly thought oh no, please be fake because I have a son already and desperatelt wanted a girl. At my 21 week scan I was told indeed, it was another boy. Ramzi was correct. My little human is here and I love both my sons to bits🥰 will defo try one more time just for a princess 🥲

Ramzi Theory

They predicted I was going to have a boy. I  thought my ultrasound was not mirror image, even though I told them it was a transvaginal ultrasound. Found out at 9 weeks I am having a boy though blood test and just had an ultrasound at 15 weeks confirming! This test was fun though! 😁

 by Reina

It was right i did the placenta one i also confirm it with sneekpeek , peakaboo and nipt

 by Seqouia T

I had them check out my 7 week scan they predicted GIRL and my NIPT results just came back and I’m finally having a GIRL after having two boys..thanks baby gender pros🙌🏽

 by Erin
Ramzi Theory correct!!

I submitted my 9 week scan and got a boy prediction. NIPT rest at 11 weeks confirmed boy!

 by Laura
Flipped transvaginal image

I sent various images and said they were all transvaginal but all the images have been flipped when they wouldn’t have needed to be? So I think the gender they have predicted will be wrong as the placenta is on the opposite side.

SURPRISE! they were right!!

 by Laura
Excellent result

I did this for both my 12week and 20 week scan, both predicted girl! We found out yesterday at 21 week with the family for a reveal and we are having a girl! Great fun would recommend- worked for us.

Ramzi predicted boy at 8 weeks. I find out for sure in a few week. I feel in my heart that it’s a boy. I’ve had two amazing daughters, lord knows my heart is longing for a little boy. If it’s wrong that’s okay too, we’ll keep trying ❤️ Fun experience and fast!

Ramzi Theory

Hello I just wanted to say I got this done at 10 week ultrasound and they said it was a girl! I went and had my blood test that came back saying girl! Then I had my new ultrasound at 19 weeks just Tuesday, it also came back and i'm for sure having a girl! I am so blessed and thankful I already have a 6 year old boy and a 2 year old boy so I couldn't be any happier! Thank you Gender Pros!

Ramzi & Nub theory done!!

Baby Gender Pros did Ramzi and Nub theory on my scans. My nub scan didn't look like a very good nub shot to me but both scans they said girl and explained why they thought so. Was confirmed I am in fact having my first baby girl. 🥰
