When you’re pregnant and wanting to find out the gender of your unborn baby, twenty weeks feels like an eternity. That big ultrasound just can’t get here soon enough! Interestingly, you may not have to wait as long as your doctor says. Here are five methods that may be able to tell you the gender of your baby as early as six weeks into your pregnancy! However, you may not want to go painting the baby’s room blue or pink just yet.

Genital Tubercle Angle Theory

There has been research to suggest that the gender of your baby can be 98.7% accuratley determined via ultrasound around 12 weeks utilizing the genital tubercle theory.  Genital tubercle is the medical term for the “nub” that forms around week 4 of gestation that eventually becomes either a penis or clitoris. While it is still too early to clearly make out boy or girl parts at 12 weeks gestation, apparently the gender can be determined based on the angle of the nub (the genital tubercle).

To determine gender based on a 12-14 week ultrasound, a profile view of the genital region is needed. A horizontal line can then be drawn along the lower portion of the spine and then another one through the genital tubercle (see below). Based on the angle of intersection between those lines, you can determine:

BOY: angle greater than 30 degrees
GIRL: lines parallel or angle less than 10 degrees

The tricky part in all of this is getting an ultrasound technician who is either familiar with this method or willing to get you a good shot of the goods so you can try it yourself!

Ramzi’s Method

According to original research conducted by Dr. Saad Ramzi Ismaal involving more than 5,000 ultrasound scans, gender can accurately be determined as early as six weeks gestation based on the position of the placenta. Dr. Ramzi found that 97.2% of the male fetuses had a placenta attached to the right side of the uterus while 97.5% of female fetuses were attached to the left side.

So, when you go in for your very first ultrasound and you can’t wait to find out the sex of your baby, ask the technician what side of your uterus the placenta is attached.

The Skull Theory

Although we couldn’t find any scientific articles backing up this theory, there is a lot of buzz around the internet on the skull theory of gender prediction. Rumor has it that you can determine the gender of your baby based on an early ultrasound by studying the shape of their skull. Baby girls are thought to have a more rounded forehead while baby boys will look more flat or slightly slope backwards. Do you have a clear profile skull shot and you’re interested in trying to determine the gender? Consider posting your ultrasound pic to one of the many “Skull Theory” discussion forums. If anything, it will be fun to see if the prediction was right when baby arrives.

DNA Testing

Do you have an extra $300-400 sitting around? If you do and you’re dead set on finding out your baby’s gender ASAP, consider DNA testing. If you are not sure what the testing does, you can visit Best DNA Test website to see how it works. Nowadays, there are several companies that will collect samples via mail and tell you your baby’s gender within a week. These tests can be done as early as 10 weeks along and are 99% accurate. How do they work? You send in a small sample of blood and they analyze the fetal cells in your blood to check for the presence of a Y-chromosome. If they detect the Y-chromosome, you are having a boy. The absence of the Y-chromosome means that you are having a girl.

DIY: At Home Gender Tests

Here are a few tests that you can try at home to predict your baby’s gender. As far as we can tell, none of these are backed by any legitimate research, but some women swear by them!

The Cabbage Test

This test apparently works because the cabbage reacts to the pH level of your urine. High pH = boy and low pH = girl. Here’s what you do:

  1. Buy a red cabbage (they are actually purple), any size
  2. Chop up the cabbage into small chunks and put in a pot of boiling water
  3. Boil the cabbage for 10 minutes then remove from heat
  4. Head to the bathroom and pee in a clean cup
  5. Combine equal parts of your urine with the boiled cabbage water

If the mixture turns PINK or RED, you are having a boy. If it turns PURPLE, you are having a girl.

The Baking Soda Test

Similar to the cabbage test, this one works by testing the pH (acidity) of your urine. All you have to do is add a tablespoon or so of baking soda to your urine sample. If it fizzes and bubbles a lot, you are having a boy. If there is no reaction, you are having a girl.

The Ring Test

This is an old gender wives’ tale that is always fun to do in social settings! Take one of your rings and tie it to a long piece of string, dental floss, or even a piece of your hair (which some believe makes the test more accurate). Lie on your back and dangle the ring directly over your pregnant belly. You can also have someone hold it for you. Be patient and the ring will eventually start to move. If the ring swings in a circular motion, you are having a girl. If it swings side-to-side in a straight line, you are having a boy.

In the end, don’t stress out or worry too much about whether any of these gender prediction methods, or even the big 20 week ultrasound, are correct. Before you know it, you’ll be holding your little boy or girl in your arms and nothing else will matter.
