Know the Sex of Your Baby at the FIRST Ultrasound!


My daughter at 13 weeks gestation -- can you tell?
Finding out the gender of the baby is one of the biggest things many families look forward to during pregnancy, whether they have a preference or not.

Most average pregnancies under OB/GYN care in the United States undergo two ultrasounds -- one at the end of the first trimester, around 9-13 weeks, and another around the end of the second, around 18-22 weeks, the latter being the "gender ultrasound" most frequently.

But what if you could find out at that first ultrasound, and NOT because you can see baby's family goods? According to a certain study, you can with 97 percent accuracy!

Researchers did a transvaginal ultrasound (you know, the fun wand up your vagina) at 6 weeks on more than 5,300 women and hypothesied gender due to one marker. Then a transabdominal ultrasound (the one on your belly) at 18-20 weeks, and their method of gender determination was right 98-99 percent of the time! 

Obviously you're wondering what they could possible see at 6 weeks gestation that would tell them anything about the sex of the baby, right?

The placenta!

Or more specifically, the location of the placenta -- 97.2 percent of boys had their placenta on the right side of the uterus at that 6 week ultrasound, and 97.5 percent of girls had theirs on the left. Crazy, isn't it? According to their study, this method should be considered "highly reliable" in determining gender within the first few weeks of pregnancy.

I tried to look at ultrasounds of mine and many of my friends, but I'm no radiologist, so I'm not quite sure where the placenta is, especially in some of the less clear images. Apparently if your first ultrasound was transabdominal, the image is flipped, so you'd reverse the sides.

Get out your ultrasounds, ladies! Was this true for you?

I have herd this before and from my ultrasound with my little it was right. The position if my placenta was on the right side. I am having a boy and he made it know very clearly that he was a boy.

AllI know about my last ultrasound was that it was anterior...

Weird. No one told me where my placenta was beyond anterior with my first and safely away from my scar and cervical opening with my second.

I won't do a transvaginal ultrasound, though. If they can't see it from an abdominal scan, it's too risky, IMO. The only one I ever had, my baby died the next day. Outside of being fairly certain I'm having an ectopic pregnancy, I will never do it again.

Weird! When I was pregnant with twins, my son was on the right and my daughter was on the left!

That is really interesting.  I wonder what placenta accretia and previa would count for...

All mine were anterior and over the opening but no idea left or right... but I have 3 girls. To bad i don't know a U/S tech to read them :)

My placenta was all the way in the front of my stomach in front of the baby, not to the side or anything. So I guess they wouldn't of been able to tell me!
