I was not prepared to learn the sex today since I'm only 13 weeks and I totally thought that you had to at least be 20 weeks??? But we totally saw a teeny tiny pee pee!
Just beware - both boys and girls have "outies" at this stage. There is something called "the angle of the dangle" that you can look up. Basically says if the dangle is angled one way, it's more than like a boy, and the other way a girl. We didn't see any dangle during our NT scan, so I don't remember which way is which.
Hope that all of your results were good.
She said that you really can't tell for sure until 15 weeks plus.... but she said she would be really surprised if this baby turned out to be a girl We saw a little nub between the legs from below... not a side angle... so the "angle of the dangle" is hard to tell that way. If it is a girl... that will be a very welcome pleasant surprise for me since that's what I want.... but I am just going to surrender to the idea that it's a boy for now.
Yay! At 11 weeks both boys and girls look about the same but by 13 weeks there is often a pretty discernible difference. By 15 weeks there's no mistaking it.
At 12 weeks pregnant the fetus will be about 45 to 50 millimeters
(less than 2 inches) CRL (head to butt) length, thats just a little more
than the width of two U.S. pennies (one cent coins).
The genital tubercle
(nub) area at 12 weeks pregnant will be about the size of a 'pin head'.
On ultrasound scans; looking through, layers of skin, womb and amniotic
fluid it will be difficult to see.
Waiting until 16 weeks
pregnant when the fetus is about three times bigger and gender changes
done is a better time for that first 'look'.
Development of the male external
genitalia is dependent upon dihydrotestosterone which is produced by the
testes. As the genital tubercle is elongating and growing to form the
penis, the urogenital folds which lie on either side of the urogenital
membrane begin to move towards each other forming a groove, this is
known as the urethral groove. The urogenital folds fuse together on the
ventral side of the developing penis, enclosing what will now become the
spongy urethra.
11 week old fetus
( Fetus size = 2.5 inch, 64 mm )
With
a boy, the genital tuber will form the glans penis (4). The body of the
penis will be formed by the fusion of the urogenital folds, this fusion
is not yet completely finished (7). The scrotum (6) is formed by the
fusion of the labioscrotal folds (2). The Raphe [line] of the scrotum
(5) corresponds to the zone of fusion of the labioscrotal folds.
At
this stage of development, the testicles are located in the abdomen.
They will not go down into the scrotum (6) until about the seventh or
eighth month of pregnancy.
The foreskin is formed in the twelfth week of development.
In the absence of the SRY gene, of the Y chromosome, a female embryo will develop.
The
development of the female external genitalia is promoted by the
presence of estrogen and other hormones within the maternal system. The
phallus described earlier continues to grow to become the clitoris.
Meanwhile, the urogenital folds are developing into the labia minora.
Their development is similar to that in the male. They grow up along
side the phallus except that in the female, they fuse only at the most
posterior aspect (bottom) to form the frenulum labiorum pudendi or
fourchette.
The labioscrotal folds continue to grow as well,
fusing at their most posterior and anterior portions to form labial
commissures. The portions of the labioscrotal folds which do not fuse
form the labia majora.

20 week old fetus
(Fetus size = 7.25 inch, 185 mm)
Girl
With
girls, the genitals are formed starting from the same embryonic bodies
as those which form the male reproductive apparatus.
The urogenital and labioscrotal folds are not joined as with boys. They will respectively form the Labia minora (7)[small lips] and Labia majora (4) [large lips] of the vulva. The genital tuber will form the clitoris (3).
Ovaries
are not identifiable until after the twelfth week. In girls, the
ovaries contain over six million eggs, this decreases to approximately
one million by birth and will be reduced to about 400 by the time of
puberty.
I had my NT ultrasound today too, and the ultrasound tech said the same thing (it looked like a boy) but I'm not going to go buy blue baby stuff just yet. I'll wait for the next ultrasound to be sure.
We had our NT Scan yesterday and was shocked when he told us his string guess is girl! I had no idea they could tell this early, i was only 12 wk 4 days. My doctor said not to go out and buy anything just yet but he is almost never wrong. Omg! And I was totally thinking boy!
I had my NTS today, and the ultrasound technician told me the same thing -- that it looked probable that it's a boy. I had read this thread a few days ago, so I asked her how she could determine that it was a boy when I was this early along. She said that the clitoris and the penis tend to be about the same size at this stage of development for the fetus, but that the clitoris usually points down and the penis points up. She said that it appeared to be pointing up on my 3D ultrasound and showed me what she was looking at. She said that we couldn't know for certain until about 18 weeks but that her bet would be that it's going to be a boy. Pretty excited -- it all seemed so much more real today. I could see the baby kicking and sucking his thumb. What a difference a few weeks makes!
Re: NT Ultrasound good... and... IT'S A BOY!
She said that you really can't tell for sure until 15 weeks plus.... but she said she would be really surprised if this baby turned out to be a girl We saw a little nub between the legs from below... not a side angle... so the "angle of the dangle" is hard to tell that way.

Make a pregnancy ticker
Congrats!! We are having a boy, too and almost everyone else around me who is pregnant is having a boy!

9 week old embryo - 11 weeks Pregnant
2. Labioscrotal folds
3. Legs
4. Genital tuber
7. Urethral groove
8. Urogenital folds
At the ninth week, there are not yet any notable differences.
The boy is on the left and the girl on the right. You find the same structures on both fetus.
