First trimester hormone levels and gender.

I ran across some articles and studies today that showed girls typically have higher hCG and PAPP-A levels than boys do and thinner neck fluid measurements on NT scans. Boys had lower hormone levels and more fluid in the neck. I was wondering if anyone had their numbers from the first trimester screen and it has proven to be accurate for them? From what I've noticed, it seems the farther the readings are above or below the average the more accurate it's been at indicating gender. Has this proven true for anyone?

Here's a link that simplifies it pretty well:

all I know is with this pregnancy I've had A LOT of different hormonal changes than I did with Zeke....I was moodier, I was nauseated all the time, I had morning sickness...it was just a completely different pregnancy and completely different symptoms...I just chalked it up to she's a girl and it may have been different hormones that caused it.

I found another website discussing the correlation and they were interpreting the results wrong and swearing it didn't work. Like they took only one hormone result when you need the relationship between both of them or one was high and one was low and then said the result was wrong when both need to be either high or low or it's back to 50/50. There were definitely a few opposites, but other forums I went to it was nearly always right when the two numbers were both on the same side of average.

I found the theory from googling after looking into why my hormone levels were through the roof on my first trimester screen, 95th for hCG and 99th for PAPP-A. And my nuchal thickness was at 25th, far below average. I then ran across the studies that showed average NTs were low for girls (mine was well below that average as well) and that girls had higher hCG and PAPP-A. I have the exact numbers this time since I got the lab printout. I only got the percentages on the hormones with my last two, no NT scans. RJ was in the 30th percentile range on both and Brighton was perfectly average for both which I found odd considering how crazy his hCG was in the beginning. I'm hoping the theory ends up being correct for me this time, but I'm going to look for reasons why it could be opposite as well (my risks are 1 in 10,000 so nothing wrong). I have 2-1/2 times the average hCG levels and 4-1/2 times the average PAPP-A levels. That along with the super low neck thickness is making me optimistic. I was really hoping others would share their results though, if they had them.

My hcg levels were always incredibly low, 2 boys. So it fits for me

Good to know! We've opted not to wait on finding out gender so fingers crossed I'm not a freak on this one too. LOL

mine are always about average so it wouldn't work for me

That could be why they say if you have morning sickness it's a girl. For me this was very true.

I've had no morning sickness what so ever and I'm having a girl

Not everyone gets MS though regardless of gender. Studies have shown women carrying girls tend to get morning sickness more frequently and more severely than women carrying boys.

my levels are always very high..1 girl and 3 boys

For those that are responding, are you going by the numbers on your first trimester screen or just early pregnancy? And also, are you having just high hCG and normal or low PAPP-A or also a high PAPP-A with high hCG on the first trimester screen?

At 5 weeks 1 day, my levels were 8000. Not out of the ordinary but everything I've looked at says those levels are on the higher side for that gestation. We couldn't see anything but a sac at that point.

Thanks for replying! But I don't mean a regular beta level in early pregnancy. I mean the levels specifically on the first trimester screen they draw to assess Down syndrome and trisomy risk. Do you happen to know those levels?

Geeze! When are you finding out?!?!

I don't have another scan until mid April unless they decide to give me one at my appointment on Monday.
