The baby is still small at 10weeks I know when they did my second ultrasound I was 18weeks and they could have been able to tell if my baby would have cooperated. I dont know the exact weeks though

I think around the 15th or 16th week they can start to tell... I had one at 19 weeks, and my baby was all curled up so I couldnt find out, I get to wait til may 25th to see if I can find out now...

Well jill had said 16 weeks but my other friend said 20-24 weeks so the baby is fully developed and you can tell if the baby is a boy or not. Im not sure but I have an u/s may 27 at 16 weeks so I can let you know then ! Lol

Usuallly about 17 weeks. I had one at 18 1/2 and they told me it was a boy hands down.

Grrrrrr I have to wait another ten weeks?!?! Goodness, this pregnancy thing takes longer than I expected!

Itll go faster dont worry

My doc told me they normally like to wait till 20 weeks to be accurate*

Hey join the club im barely 14 weeks, seems like forever! Lol

Id say around 16 weeks. I found out at 18 weeks and then they double checked for me at 22 weeks to be sure lol I have to post the pics of him at 22 weeks theres no mistaking its a boy. Be patient the time will fly. I remember when I first found out I was preggy on dec 28th and here I am 25 weeks soon to be 26 on monday. Now im nervous cuz I know I only got 3 months left ~ erica.

It depends on the doctor but I was told at 16 weeks and we could see it very clear but some would even try til 18 weeks.

They can tell as early as 14 weeks in some cases, however since the baby is much smaller and the genitalia is still forming they prefer to wait because little girls, almost look like they have a penis in the beginning, so the accuracy is much lower. Most doctors prefer to wait until at least 16 weeks, but favor more towards 18-19 weeks, provided the baby cooperates with them. The beginning and very end of pregnancies always seem to drag on, but once you get to about 16 weeks along, you start to form a belly, find out the gender in some cases, everything speeds up. Just slow down patience is the key in pregnancy.

One time I found an artical about determining the sex and they had done a study and they could tell as early as 11 weeks but I think it was only like 60% accurate but by 12-13 weeks it was nearly 100%. Ill try to find it again so you can read it.

Cool - i'd love to get my hands on it!

I found these old wives tales. Here are my experiences with them:


if your left breast is bigger than the right during pregnancy, you're having a girl. If the right is bigger, it'll be a boy. If they are the same size, you're in for a surprise!
a boy!

if you get moody during pregnancy you are more likely to have a girl. This is because all women are moody, and when carrying a girl you become doubly so.
a boy!

if you carry the baby out front (others can’t see your pregnancy from behind) then you will have a boy. If others can tell that you are pregnant when looking at you from behind, then you will have a girl.
not showing yet.

have the mum-to-be pick up a key. If she picks it up by the round end, it will be a boy. If she picks it up by the long end, it will be a girl. Should she pick it up at the middle, twins are on the way.
a girl.

if the mother's age at conception and the year of conception are both even or both odd, the baby is a girl. If one is even and one is odd, the baby is a boy.
a girl.

ask the mum-to-be to pick a number. Match the number with the corresponding letter of the alphabet (a=1, b=2 etc). Then ask her to choose a name beginning with that letter. If she chooses a boys name, it will be a boy. If she chooses a girls name, it will be a girl.
a boy.

hang a gold pendant (preferably one the mother wears often) over the palm of the mother’s hand. If the pendant moves in a circular motion, it will be a girl. If it swings back and forth, a boy is on the way.
a boy.

if you suffer from acne during pregnancy, you will have a girl.
a girl.

what side does the mum-to-be lay on while she's resting? If she lies on her left, it's a boy; on her right, it's a girl.
a girl.

if young boys (pre-school age) show interest in you while you're pregnant, it will be a girl. If they ignore you, expect a boy.
haven't been around any pre-school age boys.

ask the mum-to-be to show you her hands. If she shows them palms up, it's a girl; palms down, a boy.
girl.

if you dream of girls, you will have a boy. If you dream of boys, you will have a girl.
i dream about a boy, so a girl.

if you crave sweets, a girl. If you crave salts, a boy.
a boy.

there's reddish highlights in my hair: it's a boy.
yep. A boy.

mothers feet are no colder than usual: it's a girl. Colder? A boy.
a boy.

if you're carrying your baby high, it's a girl. If you're carrying your baby low, it's a boy.
not showing yet.

if the baby is very active, you're having a boy.
baby not big enough to move yet!

if the baby's heartrate is less than 140, a boy. If greater than 140, a girl.
a boy!

i guess the jury is still out.

Well, good luck. I know you are so anxious to know what you are having but just be patient! He or she will let you know soon enough! Lol

There is a disparity in the age and quality of some of the ultrasound equipment, as well as a difference in the experience level of technicians, which makes it difficult to accurately state one gestational age at which ultrasound can always detect fetal gender. Some of the reports in the literature are misleading because they use study protocols, which make use of the best and latest devices.

Even though studies are now reporting 100 percent accuracy in determining fetal gender between 11 to 16 weeks of gestation, in the average clinic situation, fetal gender identification is often not undertaken until at least 16 weeks, and is often not reliable until 20 to 24 weeks -- and this is when the baby cooperates fully!

In a study by whitlow, published in ultrasound in obstetrics & gynecology, a sample of 524 women underwent a detailed assessment of fetal anatomy at 11 to 14 weeks of gestation by means of transabdominal sonography and transvaginal sonography (26 percent). Fetal gender was identified and was confirmed at birth. The overall success of correctly assigning fetal gender increased with gestational age. At 11 weeks predictions were correct 46 percent of the time, at 12 weeks 75 percent, at 13 weeks 79 percent and at 14 weeks a 90 percent success rate was reached.

An article by efrat in the same volume (ultrasound in obstetrics & gynecology,may 1999,) assessed the accuracy of fetal sex determination at 11 to 14 weeks of gestation in 172 singleton pregnancies. The accuracy of sex determination increased with gestation from 70 percent at 11 weeks, to over 98 percent at 12 weeks and 100 percent at 13 weeks. Male fetuses were wrongly assigned as female in 56 percent of cases at 11 weeks, 3 percent at 12 weeks and 0 percent at 13 weeks. In contrast, only 5 percent of the female fetuses at 11 weeks were incorrectly assigned as male and this false-positive rate was 0 percent at 12 and 13 weeks.

Mazza, in the same volume, demonstrated that when the biparietal diameter (distance between the temples) of the fetus is greater than 23 mm, an accuracy rate of 100 percent was achieved.
