Know Your Baby’s Sex Long Before 20 Weeks

For all of you who become obsessed with finding out the sex of your baby as soon as you get the news you’re pregnant (*solidarity fist bump*), here’s a method I hadn’t heard of until just this week: placenta placement.

Also called Ramzi’s Method (after original research released in December 2007 by Dr. Saad Ramzi Ismail, an ultrasound supervisor/instructor at NWHC-High Level Hospital-Alberta), the idea is that the location of the placenta – on the right or left of the uterus, from the doctor’s point of view – can predict the sex of the baby as early as 6 weeks.

The study looked at 5,376 pregnancies over a period of ten years, and the results were accurate to an amazing 97%! For male fetuses, placenta location at 6 weeks gestation was on the right side of the uterus 97.2% of the time (2.4% on the left), and for female fetuses, it was on the left side 97.5% of the time (2.7% on the right). In a small percentage of cases, the placenta was located in the center.


The catch is that you can’t just look at your ultrasound photos when you get home, since the type of ultrasound and the placement of the wand can sometimes alter the image. If you want to get an early guess about your baby’s sex, you’ll have to specifically ask your ultrasound tech to tell you where the placenta is located. Not every tech will oblige, but it’s worth a shot if you’re curious!

This method can be used for early detection of a fetus’s sex in cases where certain genetic disorders are passed along to either males or females, but it’s not likely the practice will become standard for the average pregnant couple, considering the ethical issues surrounding uncontested abortions based on the baby’s sex.

Here’s the full research report on Ramzi’s Method.

Did you know about the placenta placement test? Did you ask your ultrasound tech about it, and was she right?
