I wouldn’t even take a guess from a trained professional at that point.  All babies have outer parts until later, so it’s not a reliable thing and really hard to tell the difference that early.  Some people think you can guess from the “angle of the dangle”, but I’m not sold on that either.

My husband’s cousin found out at 12 weeks, her baby just happened to be in the right position.  Not sure if this is the norm though.

External genitalia actually starts becoming visible around 11 weeks, so it could be POSSIBLE, but very RARE, to find out the sex from an anatomy scan at 12 weeks. You’re better off getting a maternal DNA test that early on to find out the sex; its accuracy rate is about 95%, compared to the 98% offered by ultrasounds (“Tell Me Pink or Blue” is one commercial agency that does it without a doctor’s recommendation).

The bigger problem is that swelling of the labia is not uncommon in utero — so a daughter could actually end up looking more like a boy (and the “berries” may not actually be berries — but I’m sure someone has an explanation for that).

All right, I researched this a little bit more. Apparently, the odds are between 50 – 55% accurate for determining sex by ultrasound at about 12 weeks. So…hardly better than chance.

I haven’t known anyone who found out that early based off of an ultrasound, I think it would be pretty rare and I certainly would NOT count on that being accurate.  I wouldn’t make any announcements or buy any boy stuff until after 20 weeks.  External genitalia can actually still look the same at that age (both girls and boys have external genitalia early on) so I really wouldn’t count on it.

VERRRRY unreliable at 12 weeks. Don’t get too attached, just in case! your 20 week scan will be much more accurate.

CookieCreamCakes:  Interesting! 

The problem is even if they take a guess, they have 50% chance to be accurate anyway!  So I imagine it’s hard to tell what % of guesses really end up being accurate just based on pure luck (versus actualy being able to tell).

Hard to tell at that time, and I think they have a 50% chance of being right, so, obviously, reliable but yet not, lol. I’d wait to get too attached. My us lady wouldn’t even take a guess, but I had such a deep feeling it was a girl, but alas it was a boy at my 20 week, and I couldn’t be happier.

I just read on my 19 or 20 weeks summary that if th baby is a boy then the testicles are just starting to decend from the pelvis.

Both sexes have what’s called a “genital tubercle” or “nub” at 12 weeks. External genitalia, if you will. If you google “nub theory,” it will tell you how to divine what sex your baby is by the angle of the dangle. Nubs that are parallel to the angle of the spine or downward facing are more commonly present in girls, and those that angle up from the angle of the spine are more commonly present for baby boys. This is JUST a theory (not super accurate)… but we got a good nub shot that showed us a “girl” angle and she was later confirmed a girl.

Diamondgurl:  I had the same thing happen at my 10 week ultrasound! The doctor said she was pretty sure we were having a boy, and I clearly saw what looked like a penis. I even took video of it on my phone and showed our parents and friends who all saw it as well. Then at our 20 week anatomy scan, we got a nice, clear close up of a little vagina. So, who knows.

Diamondgurl:  It can be possible! I had an ultrasound done at 11wks 5dys, and my ultrasound tech told me she was 80% sure it was a boy! but not to go nuts buying boy stuff until my 20wk gender scan. Turns out it it as a boy and she was right the whole time! now I’m 36wks and cant wait to meet my little prince!
