Most parents today volition desire to find out the sex of their baby earlier birth. Ane of the most mutual ways to do this is with an ultrasound, most oftentimes performed at between xviii and twenty weeks of gestation.

Co-ordinate to a 2012 report published in the journal Obstetrics and Gynecology, no less than 69% of parents wanted to know. Amid the reasons cited, 77.8% wanted to know "out of curiosity," 68% "just wanted to know," and 66.8% did then "because it was possible."

Your Infant's Ultrasound: What to Expect

Prenatal Ultrasound

A prenatal ultrasound is a non-invasive examination that uses audible sound waves to produce images of a fetus'southward shape and position in the uterus. It is a preferred method of imaging during pregnancy as information technology neither involves radiation nor poses harm to either the fetus or female parent.

An ultrasound is routinely used at different stages of the pregnancy. While most practitioners will wait until at least six weeks to perform the commencement ultrasound, the gestational sac may be seen as early on as four and a one-half weeks, while a heartbeat may be detected every bit early every bit v.

Between weeks xviii and 20, a trained sonographer volition perform a detailed anatomy scan called a level 2 ultrasound. It is at this fourth dimension that the sonographer will measure out the size of your baby, check the major organs, measure the level of amniotic fluid to make sure that it's correct, and cheque the position of the placenta.

By this stage of fetal development, you should also exist able to find out the sex of your baby. While telling the difference tin sometimes be tricky, there are a few things the sonographer volition look for to make the determination.

Accuracy

When a sonographer does a level 2 examination, what is seen on ultrasound is far more important than what is not seen. With regards to determining sex, what this means is that the absence of a penis does not inherently mean that you have a girl.

With that being said, over 99% of ultrasounds performed between weeks 18 and xx will make the correct determination. It is but when it is performed before week 14 that the charge per unit of accuracy can drop significantly.

Co-ordinate to a 2014 study from Commonwealth of australia, which reviewed 642 fetal ultrasound results performed between weeks 11 and 14, the overall success rate in determining fetal sex was 75%. The most common fault was to assign male fetuses as female.

Girl Ultrasound Signs

When determining the sex of the fetus on ultrasound, the sonographer will look for feature features known as signs. For girls, there are two signs to look for:

Hamburger sign: This is the moniker given to the appearance of the labia and clitoris on an ultrasound. If you look closely at the image, you will see that the labia lips would wait similar to a hamburger bun, while the clitoris would resemble the hamburger patty.
Sagittal sign: Each sex has a sagittal sign. It is obtained past looking at a profile view of the fetus (known as the midline sagittal plane). In that location is a nub at the cease of the spine, chosen the caudal notch. If it is pointing downward at a x-caste bending, then the fetus is a girl.

Boy Ultrasound Signs

Y'all would think that male person fetuses would exist easier to place than females, but that's not e'er the instance. This is especially true before calendar week 14. By weeks 18 to 20, the determination for a baby boy would exist based on the following signs:

Sagittal sign: If the caudal notch is pointing upward at more than a xxx-caste bending, so the fetus is a boy. If it is somewhere in between, it may be harder to make a definitive determination.
Flow of urine: The flow of urine can sometimes exist spotted in a fetus. If information technology is moving upwardly, and then it is more likely a boy.
Male genitalia: Often be seen by weeks xviii to 20, the presence of male genitalia, including testicles, scrotum, and penis, is a clear sign of male gender.

Other Ways to Decide Sexual practice

In add-on to an ultrasound, the sex of your babe can be confirmed with an amniocentesis or chorionic villus sampling (CVS). Amniocentesis is a procedure in which fluid is extracted from the sac surrounding your baby with a needle and syringe. CVS involves taking cells from the placenta with a needle.

While both procedures carry risks, they are extremely accurate in making the determination and can return a result past as early as calendar week 11 (for CVS) and calendar week 15 (for amniocentesis).

In fact, the same study published in Obstetrics and Gynecology concluded that 65% of parents preferred to know the baby's sexual practice after an amniocentesis compared to 28% who preferred an ultrasound. This was despite the fact that 96.two% of women believed that an ultrasound was a reliable means of determining the sex of her babe.
