What are the chances the ultersound is wrong in detirmining my baby's sex?

Answer 1

Like any prenatal testing, ultrasound results are not always correct. There are "false positive" results (where a baby is wrongly diagnosed as having a problem) and "false negative" results (where the ultrasound results appear normal but the baby actually does have a problem). It is never possible to be 100% sure about prenatal testing results.
This is true when and Ultrasound Test is used to detect the baby's genda.

Research indicates that the effectiveness of the ultrasound depends greatly on the quality of the equipment used and the skill of the technician using it. There are very clearly more "false positives" and "false negatives" from ultrasound technicians who have not received special training in the use of ultrasonography, or from those who are using a less-powerful machine.

Two years ago, I went through a real nightmare. We were expecting a baby, and the doctor found it was a girl. However, he made us a special invitation to come to his office. When we arrive, the new was heart breaking. "Several tests we conducted indicate that your baby wis autistic, and with down syndrome". Gosh. Being in school, trying to start up a live, we were broaken by the news, but left everything in Gods' hand. We were given packs of books and information materials on how to handle such condition, for lifelime. We went through all this, until the delivery day. The baby was so healthy, cool, cute, and just healty. Today she's calls herself a "real princess", with no defect at all. What does that tell us?
=> False Negative.
So, the best thing to do is to be prepared. We, including the doctors, to machines, are outside of the womb. The baby is inside, and only God knows the real condition of that baby. Any other tools that are used for testing are nothing than a guess of what to expect. I am not saying that you should walk away from it. It helps to get an idea. But it is on always as predicted.

Answer 2

It depends on how far along you are and the babies position as to whether your doctor can accurately dtermione sex. If they told you a sex the cahnces of them be right are really good. It's not fool-proof though. More often it is them telling you it is a girl and it was really a boy. Usually if they say it's a boy it is... it is easier to see male parts then enything else. Ask for a print out next time and you can see for yourself just ask them to show you where they see the parts, otherwise it's hard to tell whats what!

Answer 3

I dont know the exact stats on this, but I know three or four people who's u/s tech's were wrong about the gender. If you are that worried about it, they have 3-D ultrasounds to check for gender. The only thing with those is insurance doesnt cover them, but a lot of the ones that are jsut for gender checking are $150 and under.

Answer 4

This is what our ultrasound tech told me, and she's been doing this for 25 years:
If they DON'T see a scrotum and they are pretty sure the baby was in the right position, 80% of the time, it's a girl.
If they see a scrotum, 95% of the time it's a boy.
She gave us "98% sure it's a boy" when I went at 20 weeks.
Good luck!!

Answer 5

If the person who operates it is experienced, chances for a mistake are slim. Especially if baby is in a good position and you do not have too much fat on your belly. I have a daugther and in two successive ultrasound scans two different doctors were positive that it was a girl and they were right. Picture from the ultrascan was so clear that even my husband and I, with our unexperienced eyes, could tell it was a girl.

Answer 6

Depends on when you got it done. If you had it done before 20 weeks, I wouldn't decorate the nursery on that prediction, I've had too many friends have that prediction wrong. If you had it done after 20 weeks, and they said it was a boy, they are probably right. If they said it's a girl, there is little more room for error. (That one little difference can be hidden calling for a girl, but if they see it and say boy, it's probably right). Also, how sure was the technitian? I had mine at 22 weeks and he said there was absolutely no doubt it was a girl, and that's what we got!

Answer 7

Really depends on how good your ultrasound tech was..if very experienced and seemed to know what they were doing theres a very slim chance they were wrong...also depends on how good a view the baby allowed them to have, again if there an experienced UT then they were probably right

Answer 8

A very good chance. My daughter on her last two pregnancies was told she was going to have a girl. Well she ended up with two more boys. One they said 90 percent chance she was having a girl, second one was 100 percent she was having a girl. I say don't believe them unless you can see male gentalia.

Answer 9

50/50..lol.. Actually it depends.. The later on in the pregnacy things are clearer. I had an ultrasound at 40 weeks, we KNEW he was a boy. Boys are easier to say then girls. With both my girls we got a "we can't tell" With both my boys we knew.

Answer 10

It wouldn't be the ultrasound, it would be the nurse or doctor that interpreted what the ultrasound was showing that would be wrong in determining the baby's sex.
