What is the earliest you can know the sex of the baby?

Question

My sister in law is also pregnant and she is now 16 weeks along. She told us that at about her 13th week that the doctor knew the sex of their baby is ti possible to know this early?

Answer 1

Some people claim to know as early as 12 weeks, but I doubt the accuracy of ultrasounds that early, since all fetuses start off with a genital tuber (which basically looks like a nub, or a small penis) and the difference isn't really clear until closer to 16-20 weeks. Check out this link for more info...it's very interesting!

Answer 2

Yes actually 13 weeks is the earliest but most doctors won't tell you until 15 weeks or more just to make sure nothing wants to "pop out" so to speak. They waited until i was 16 or 17 weeks.

Answer 3

I think they said 16 wks is the earliest they can guess. Unless they can get a clear shot between the legs though it is just a guess. I was told girls for both and had boys. That was at 6 months.

Answer 4

They can tell you as early as 12 weeks, but it is not as accurate as it would be at 16 weeks. If the baby is a boy, they can usually tell pretty early with about 90% accuracy.

Answer 5

I was told at 17.5 weeks that I was having a boy. That was the earliest that I have ever been told. I am not sure what the earliest is though.

Answer 6

I found out what I was having at 19 weeks!!

Answer 7

I find out (hopefully, if baby copoerates!) @ 19 weeks. Depends on the DR ./ practice.

Answer 8

13 weeks is stretching it, it would wait until the next ultrasound. we learned we were havign aboy at 15 weeks, but a penis is easier to see than a vagina.

Answer 9

bout 5 months
they can tell you what they think it is, but the genitals aren't completely formed. she will have another in another month and she should go wih that one

Answer 10

they told me that 16wks is the earliest they could tell!!
