When is the earliest that a babies sex can be determined by an ultrasound?

Answer 1

16 weeks

Answer 2

It depends on the position of the baby and the quality of the ultrasound. I somethimes determine the sex at 9 weeks by transvaginal ultrasound. But 14 weeks is the usual time.
I am an Ob&Gyn by the way

Answer 3

3-4 months ish, if you're lucky (position), and especially if a boy. Latest at detailed morphology ultrasound (5-6 months)

or else if you're really impatient there are some simple genetic blood tests that will test baby blood cells found in the mother's blood stream (i.e. standard needle procedure to draw a bit of blood from the mother, zero risk for baby / pregnancy of course). They cost about 100 dollars or so. And will give you an answer from about 2-3 weeks, yes!

good luck

Answer 4

Typically it's about 13 weeks, because a baby doesn't even develop sexual organs until the 7th week, so it is too small to determine until around 13. Which is why in case you were wondering, men are born with nipples. All fetuses are female until about the 7th week. Which proves women are the superior sex. LOL

Answer 5

I know they usually do the ultrasound at 20 weeks. But I'm sure they can tell before that . Maybe by amnio test.

Answer 6

18-20 weeks

Answer 7

I had an US at 14 weeks, couldnt tell, then at 20 weeks, and found out!!! so my guess is around the 18 week mark!

Answer 8

I know people who found out at 13 weeks, but it is typically between 18 and 22 weeks.

Good luck.

Answer 9

I was 13 weeks with mom son and 18 weeks with my daughter.
