Baby Gender Prediction: Ramzi Theory explained by Ultrasound Technicians

This article covers Dr. Ramzi’s ultrasonography Research to explain how to use this method when you are approximately 6-8 week’s pregnant and go to your first ultrasound. If you are further along in your pregnancy (closer to 12-14 weeks), try using the Nub Theory and/or Skull Theory for early gender prediction.

“Ramzi’s method uses the placenta/chorionic villi location as a marker for fetal gender detection at 6 weeks gestation, and it was found to be highly reliable. The Ramzi method correctly predicts the fetus’ gender in 97.2% of the males and 97.5% of the females early in the first trimester.” obgyn.net

Dr. Saam Ramzi Ismail conducted an extensive and controlled study of over 5,000 pregnant women. He discovered that using the direction or orientation of the chorionic villi (future placenta) is an accurate marker in determining the sex of a baby. Scientifically, it relates to a natural polarization in which male embryos have a proven pattern of being magnetized toward the right side of the uterus, and females are drawn toward the left side.
Chorionic villus form before 9 weeks’ gestation. It turns into the placenta which provides oxygen and nutrients to the fetus and removes waste products from the baby’s blood. The Mayo Clinic describes the chorionic villi as “wispy projections of placental tissue that share the baby’s genetic makeup.”

Boy or Girl? How to read the ultrasound scan when using the Ramzi Method

1. Ask your technician at your 6-week to 8-week ultrasound which side your placenta is on.

Dr. Ramzi’s study followed strict guidelines and used a control group to achieve results. Using a color flow Doppler to view the direction to pinpoint the chorionic villi location achieves high accuracy in determining the sex of the baby.
Asking your technician to use this technology produces accurate results. When chorionic villus/future placenta are on the left side of your body, you are likely having a girl. If it is on the right side of your body, it is likely a boy!

2. Look for the bright area around the gestational sac.

The chorionic villi (future placenta) are located by identifying this hyperechoic (bright white) area. It is easier to detect the placenta in some scans than it is in others.
There are cases where the scan shows multiple hyperechoic areas of brightness.
In medical terminology “hyperechoic” means:
1. In ultrasonography, pertaining to material that produces echoes of higher amplitude or density than the surrounding medium.
2. Denoting a region in an ultrasound image in which the echoes are stronger than normal or than surrounding structures.
When looking for your placenta or yolk sac in your ultrasound photo, look for the areas of higher density. If you are having trouble finding them, upload them at our Shop TheGenderExperts.com and we will help determine for you!

3. Transvaginal vs. Abdominal Orientation: Flipped or mirror image?

Unlike an abdominal ultrasound, a transvaginal—sometimes called an endovaginal—scan is done when the ultrasound wand is inserted 2 or 3 inches inside the vaginal canal in order to take photos from inside. These photos can capture images of the vagina, cervix, uterus, fallopian tubes, and even the ovaries. Internal scans are often used early in the pregnancy to assist the doctor or technician in obtaining a high-quality view.
Because of the nature of a transvaginal ultrasound, your technician will be able to determine both the left and right sides of your uterus, and therefore can help you find where (which side) the placenta is located. Both abdominal and transvaginal scans can be used when predicting with the Ramzi Method.
The debate among pregnant women who discuss the Ramzi Theory is questioning whether transvaginal ultrasounds appear to be on the “same side” as pictured on the scan because abdominal scans are “flipped” (or mirror image)
Because of this, The Gender Experts rule-of-thumb is : Not all scans are created equal for the Ramzi Theory.
Sometimes transabdominal ultrasound scans are true to the same maternal side. Abdominal ultrasounds are usually flipped, but in some cases they are not.

Technicians can help determine the correct orientation

An ultrasound photo is a 2D image of a 3D place; it’s the inside of your uterus. In a transverse ultrasound, a technician can easily tell which side of your body is which based on where the beam enters the body and can annotate your printed ultrasound photos accordingly.

The technicians that read your scan for the Ramzi Method, like The Gender Experts, look for the following:

  • Annotations on the scan, such as “TRV,” “TRAN,” “LONG,” “R/L Flip,” or “SAG.”
  • Anatomy surrounding the sac, such as ovaries, cervix, bladder, etc.
  • The shape of the sac to determine whether it may need to be rotated 30, 90, 180, or xx degrees clockwise or counterclockwise.

Scanning Planes: Transverse, Sagittal, Coronal

Scanning planes that your technician uses while scanning in the clinic can have a direct effect on the accuracy of the Ramzi Method. The orientation of the placenta depends on which scanning plane was applied. If the hyperechoic bright area appears on the right, left, top, or bottom of the picture, it could mean that it is a mirror image, but it possibly is just showing that the chorionic villi are posterior or anterior.

Sagittal Scanning Plane

A sagittal scanning plane is a view that appears to slice from left to right. Imagine looking from the right side of your belly and looking in. You can see which way is up and down, or front and back. Therefore, you wouldn’t be able to know right vs. left. It is a “long view,” so the only placenta location determination that is possible in this view is whether your placenta is anterior or posterior (toward the front, or toward the back). This is why sagittal scanning planes negatively impact accuracy for Ramzi Theory.

Transverse Scanning Plane

Ramzi Theory scans should be in the transverse plane in order to accurately determine which side the future placenta is on. The transverse plane is like looking from your belly button in. This allows you to see which side is left, and which side is right.

Using these photos as a guide is a great way to predict for fun. It may not always work because there is always room for error. If you are still unsure, submitting your Ramzi Theory scan to us produces a high accuracy rate. Correct placenta position determines whether you are carrying a boy or girl! Even though the accuracy of the Ramzi theory is significantly higher than traditional old wives’ tales, the gender predictor methods online are intended to be used for entertainment purposes.

Confirmed Scans Gallery

This is a confirmed internal boy scan at 8 weeks’ gestation. Notice how the baby is sitting right in the middle. However, the Ramzi Theory states it is not where the baby is, but where the placenta is. The placenta is technically the chorionic villi at this stage. The future placenta is on the left side of the picture, or right side of the body. To view all confirmed Ramzi scans, visit our Confirmed Scans Gallery Other clues to help make a gender prediction is locating the yolk sac because it normally attaches close to chorionic villi.
The yolk sac on the scan example is leaning toward the left side of the picture (the right side of the body).

Further evidence to indicate male fetus is the decidual reaction noted on the scan. This is also on the right side of the body. Identifying the decidual reaction is looking for a “wall” that surrounds the sac.
Decidual reaction is a thickening of the endometrium seen in early pregnancy. A double decidual sac sign is one of the first signs that pregnancy has occurred.

Ramzi Theory Frequently Asked Questions

1. Does the Ramzi Method work for twins?

If the twins have their own placentas, (which is the majority of the time), the Ramzi Theory should be able to work to predict each twin’s sex. However, not enough studies have been done on using the Ramzi Theory for twins. Again, send us your ultrasound photos TheGenderExperts.comat our Shop, and we will be happy to have our experts take a look for yolk sacs, chorionic villi, and placental locations in relation to the rest of your uterus. 

2. Does it matter if I ovulated from my right or left ovary?

No. A woman can release from her left ovary, and the baby can implant on the right side of her body, and vice versa.

Many women only have one functioning ovary. Therefore, they are just as likely in producing a male or a female, regardless of which ovary it is being released from. There is no correlation from ovulation side for determining on which side the placenta will form.

3. When does the Ramzi Theory work?

The Ramzi Theory can be used to predict the fetus’s sex determination as soon as the chorionic villi begin to form, which is before the placenta is formed. That’s as early as 5 or 6 weeks’ gestation! When you go in for your initial pregnancy ultrasound to determine that you are, in fact, pregnant, ask your technician to do a transverse plane scan and mark the right and left sides of your uterus on the screen or photo. From there you can predict what sex your fetus will grow into.

It is possible to predict using a later scan; however, accuracy would be affected. This is because as the placenta grows, it becomes more difficult to identify which side it began forming on due to its increasing size.

If it’s difficult for you to determine, send us your scan and we can help you!
