Would a boy get higher downs risks?

[JoeyLin]

I think it's a theory that more boys have downs than girls.
Could the downs risk assessment at 12 weeks also mean that boys are given higher risk assessments than girls?

Hi, this is the only thread I could find regarding risks of Downs syndrome - I have a complicated pregnancy due to my own health conditions. I got a call saying I am 1 in 5,000 risk of DS. Is this considered low risk ? The doctor wasn’t a specialist in this so wasn’t sure herself but expected that to be low risk which I am hoping for - Please could I have some advice x

1 in 5000 is about as low risk as you can get. My midwife said they only go up to 1 in 5000

Yes, that's low risk. High risk cutoff is 1 in 150.

Thankyou so so much!

Thankyou!!!

Slightly more males than females have Downs - it's about 1.3 : 1 on most studies, so male foetuses would be slightly more likely to have Downs. However, the risk score you get though is based on maternal characteristics (particularly age), some biochemical markers and markers from the sonogram (things like a thicker fold at the back of the neck, shorter long bone length, bowel appearance). Studies (albeit with small sample sizes) haven't found any difference in the incidence of sonographic findings between male and female foetuses.
