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

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.
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
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!

Twin boys! Love that it was correct!
I submitted my scan and received an email saying it was a girl . Turns out it was actually right. Wish I used it for my last pregnancies 🙂
I knew you were right as soon as I got my prediction because I could FEEL she was a girl!
thank you!
I used my 11 week ultrasound based on the skull and where my placenta they said i was having a girl i just received a call from my doctor that i am indeed having a girl they were right im so happy!!
It was spot on. We weren't finding out what we were having until birth so it was fun to do this. I was surprised it was correct.
I had the ramzi, nub and skull theory done, yous said I was having a girl well it got confirmed yesterday I am having a girl.. yous were correct
This was truly exciting. I have 3 boys and want a girl more than anything in the world. I was really scared to get my hopes up with gender pros predicted girl. I was shook to find out my last baby... is a a girl. I wish I would have never doubted!
Told me based on my US it was a girl and it’s been confirmed girl thru blood work and 2 scans! After 3 boys I’m glad it was right! lol
I submitted my scan and was told it was a boy due to the location of the placenta. Got my Maternity21plus results and it's 100% a boy.
Recommend to anyone looking to find out a bit more about their baby!!
All three theories said I’m having a girl . But my NIPt test result said it’s a girl. So this is just for fun but its really accurate!!
I could not wait for my NIPT results, so I thought I would give the Baby Gender Pros a fun chance. They were correct. We are having a boy!
You predicted my baby to be a boy with all 3 theories. Scan later confirmed a boy and  i also tried  with the scans of my now  1 year old is definitely a girl! You got both right! thank you
Had results back and its very clear im having a little boy. So gender prediction was right, I know this isnt a guarentee but quite alot of fun! I will know to try again next time
I sent in my 12 week scan for both the skull and nub theory. Both predictions guessed girl within the estimated time frame. We booked an early 16 week scan and they told us its a girl. And just for triple confurmation today at our 20 week scan we was told again a little girl is due. Our results were spot on and we couldn't be happier.
Sent in my 6 week ultrasound and it was predicted boy, and NIPT testing confirmed a boy. It was fun and we were also sure it was a boy, so glad i tried it!
Very fun, Â got told was a boy and found out today we are in fact expecting a boy 💙
Great gender prediction service.
I submitted my 6 week scan and they told me I was having a girl , so I got an ultrasound and it confirmed it was a girl. Very happy we tried!
Sent my 7 week scan in and your results came back as girl, to be fair it followed your guidelines, at my 11 weeks scan looked like according to your guidelines I was having a girl, I was so confused. Got my NIPT back and it’s a girl!
I submitted my ultrasound scan at 7w3d for the Ramzi theory. Gender Predictor Pros predicted that I was having a girl based on placenta position, which I had hoped was wrong because I already have a girl and we were hoping for a boy. Had the NIPT blood test done through my OB office at 11 weeks… it’s a girl! This was confirmed at my 20 week anatomy scan as well! good job guys!
