Like any sound, it penetrates through the obstacles, partly reflected from them. Ultrasonic device emits a signal, and it is reflected (giving echo) from different tissues with different force, it is an echo and recorded, becoming a picture. Effects on the fetus due to these sound waves. It is unlikely that the embryo can not hear them, it has no ability to hear high-pitched sounds. I must say that up to 16-17 weeks, the organ of hearing does not sufficiently developed, in order to hear at least some sounds. Often during the survey can be seen as the kid turns away from the sensor, but it has more to do with his pressure on the abdominal wall, than the influence of ultrasound on the fetus.

so as i understood you right, the ultrasound has less influence on the early terms and it doesn't harm te fetus. but the more term is the bigger influence is?

No, I don't think you. I meant that ultrasound is not harmful for fetus but the gender can be known for sure at later term.

oh, i see.
so it's too early for you to know the gender?
don't you want to keep it in secret?even for you?

in secret?! No way))) I'm not so patient to wait for such a long time. BTW want to decorated room for children and should know how to do it and what colours to use)

but you always can buy things and prepare room in such a way that it can suit both:)

probably a couple of weeks left to know the gender, so I'll wait till some exact result of ultrasound.

i read that very often ultrasound shows wrong results!

Can't say that it is very often but there are cases when the result was wrong. Also there is 3D ultrasound now and it is difficult to make a mistake with such technical progress. Again everything depends on the term.

and on the position of fetus. sometimes our miracle turns so that the doc can't see anything...

yes, it is can be like this but it is not our case, so hope we will see everything clearly)
