A friend has today given birth to a baby boy. She had 4 ultrasounds throughout her pregnancy that all said girl, the baby was born this morning and is very definitely a boy mellow.gif

When sonographers get it wrong, is it usually scan says girl/baby is really a boy (as opposed to the other way around?) I'm guessing its pretty rare, I haven't ever known anyone to have this happen before!?

I know a couple of stories of this happening.

When I had my last baby I met a lady who had been told she was having a baby girl but ended up delivering a baby boy instead.  After the baby was born she said she asked the midwives how 'she' was and said the midwives then looked at her strangely and said 'she'?  That was when she found out that the little girl she was expecting was infact a little boy.  

My best friend decided she would find out the gender of her last (fourth) baby after not having found out with her other 3.  She was told several times that she was having a girl, and after 3 boys she was very excited.  She ended up having one more scan before giving birth and was then told a boy at this scan.  Boy #4 ended up arriving.  He was in a breech position up until the last scan so that might have had something to do with it.  She regrets trying to find out the gender during the pregnancy and if they had have said boy all along she would have been happier with that.

I have a friend who was initially told girl that turned into a boy, but she was initially told a girl during the 1st trimester scan so not very accurate then I guess.

I had a GF who from the 20wk scan was expecting 'Olivia' and then I was surprised when the txt came to announce the arrival of 'Oliver'.

For me my 12wk scan I was told BOY, then at 20wk scan told GIRL and had DD for #3, but that was an early 12wk scan.

I have heard it can happen (wrong gender prediction from scan)but dont know anyone  personally that it has happened to.  I only found out the gender of my younger 2 and they got it right.

Yes it 'can' happen but with modern technology, it doesnt happen too often. I have known of this happening to one person, however, she was only given a 70% chance that it was a girl and it turned out a boy. I think sonographers are more likely to be wrong if they determine that a girl is a girl based on a lack of male bits. I think it is meant to be pretty spot on if they see the 3 lines typical of a girl. This was what I was told. I am having a girl and was told 99.9% girl as they clearly saw the 3 lines.

It's much more common for it to be wrong if you get told a girl at the gender scan.There's no denying boy bits as they're pretty clear to see on a scan when the baby makes it obvious, but as PP said the absence of boy bits can very easily get mistaken for a girl, when they simply can't get a good enough look in that area to be sure. I found out with DS, and he bared himself to us, and I'm going to find out again, but unless they can tell me with more than 95% certainty that it's a girl, then I'll assume it still could be either.

My friends sister is 27 weeks pregnant and at her 12 wk us they told her it was a boy definately (I always thought this was too early). Then at her 20 wk they couldn't tell and then she had another one as her mum worls at a doctors office and they are sure it's definately a girl! I actually feel really sorry for her because now she has no idea what to expect.

I was told at my 20 week scan i was having a boy. I then went on to have another scan at 32 weeks (due to bleeding) and was told was having a girl.

Needless to say we didnt know either way in the end and Mia was born 8 weeks later

Hopefully 3D scans are more accuarate ME.

I was told 80% girl at an early 13 week scan and then boy at the 18 week scan but neither of my scans were 3D.

I could have sworn I was having a girl, but now that I am used to the idea of him being a boy, I'm expecting a boy to come out! Guess we'll find out in 5.5 weeks.

Does anyone know if the people who had been incorrectly told at their ultrasounds had 2D or 3D ultrasounds?

Happened to a friend a couple of years ago. TOld all the way through it was a girl and ended up with a boy.

Sunnycat, the guy doing my 3/4D scan actually switched back to 2D for gender as he said that despite what people think 2D is actually much more accurate.

My brother and his partner have had it happen twice.

First child they didn't find out and had a girl.

Second child, my brother didn't want to know but his partner did. She was told a boy at her 20 week scan. Because my brother didn't want to know, they stuck with buying gender neutral clothes. Lucky because DD2 was born.

Third child, they both wanted to know, and had a 3D scan. They were told definitely a boy, but instead DD3 was born.

I'm guessing in both cases the umbilical cord was mistaken for a penis.

EFS.

99% are wrong? I'm not sure what you are referring to here?

huh.gif

The vast majority of gender prediction scans are actually right... I don't know of anyone who has had a wrong prediction.

Out of all the people I know who have had gender prediction scans, only one of them has been told the wrong sex.  A 'girl' who turned out to be a boy.  That's pretty good odds, I reckon.

I know of two people who've been told they are having girls, only to give birth to boys.

It seems to be far more common that a boy gets mistaken for a girl in a scan than the other way around.

Pretty sure thats a boy hahaha!

The sonographer started the scan with the whole "nothing is 100% speech" and by the end of it shes like well i can 100% say thats a boy!!

Have had another scan since then and he happily showed off his goods then too.

This is precisely the reason why we didn't find out with the twins, or with bubba #3!
I couldn't bare to think we were having one sex and end up with the other!

Good luck to you all!

My cousin was told girl at 19 weeks. She gave birth to a boy.

I found out with #1 & #2. Was told girl at every scan we had (and they were obviously right).
