Most parents today will want to find out the sex of their baby before nascence. 1 of the almost common ways to do this is with an ultrasound, most frequently performed at between eighteen 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. Among the reasons cited, 77.8% wanted to know "out of curiosity," 68% "merely wanted to know," and 66.8% did so "because it was possible."

Your Infant'due south Ultrasound: What to Expect

Prenatal Ultrasound

A prenatal ultrasound is a non-invasive test that uses audible sound waves to produce images of a fetus'due south shape and position in the uterus. It is a preferred method of imaging during pregnancy as it neither involves radiation nor poses damage to either the fetus or mother.

An ultrasound is routinely used at different stages of the pregnancy. While nigh practitioners will wait until at to the lowest degree vi weeks to perform the first ultrasound, the gestational sac may be seen every bit early on equally four and a half weeks, while a heartbeat may be detected as early as five.

Between weeks xviii and twenty, a trained sonographer will perform a detailed anatomy scan called a level 2 ultrasound. It is at this time that the sonographer will measure the size of your baby, bank check the major organs, measure the level of amniotic fluid to make sure that it's right, and bank check the position of the placenta.

By this stage of fetal development, you lot should besides be able to detect out the sex of your baby. While telling the deviation can sometimes exist tricky, there are a few things the sonographer will look for to brand the determination.

Accuracy

When a sonographer does a level ii exam, what is seen on ultrasound is far more important than what is not seen. With regards to determining sex, what this ways is that the absence of a penis does not inherently mean that y'all take a daughter.

With that being said, over 99% of ultrasounds performed betwixt weeks xviii and 20 will make the right determination. It is but when information technology is performed earlier week 14 that the rate of accuracy tin driblet significantly.

According to a 2014 study from Australia, which reviewed 642 fetal ultrasound results performed between weeks eleven and 14, the overall success charge per unit in determining fetal sex was 75%. The most common fault was to assign male fetuses as female.

Daughter Ultrasound Signs

When determining the sex of the fetus on ultrasound, the sonographer will expect for characteristic features known as signs. For girls, there are ii signs to await for:

• Hamburger sign: This is the moniker given to the advent of the labia and clitoris on an ultrasound. If yous look closely at the image, you lot will meet that the labia lips would expect similar to a hamburger bun, while the clitoris would resemble the hamburger patty.
• Sagittal sign: Each sex has a sagittal sign. It is obtained by looking at a contour view of the fetus (known equally the midline sagittal plane). There is a nub at the end of the spine, chosen the caudal notch. If it is pointing downward at a 10-degree angle, then the fetus is a girl.

Boy Ultrasound Signs

You would think that male fetuses would be easier to identify than females, but that'south not always the case. This is especially true earlier week 14. Past weeks 18 to xx, the determination for a babe boy would exist based on the following signs:

• Sagittal sign: If the caudal notch is pointing upward at more than a 30-caste angle, then the fetus is a boy. If it is somewhere in betwixt, it may exist harder to brand a definitive conclusion.
• Flow of urine: The flow of urine tin can sometimes be spotted in a fetus. If it is moving up, then it is more likely a boy.
• Male genitalia: Oftentimes be seen by weeks 18 to xx, the presence of male genitalia, including testicles, scrotum, and penis, is a clear sign of male gender.

Other Ways to Decide Sexual activity

In addition to an ultrasound, the sex of your baby tin 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 bear risks, they are extremely accurate in making the decision and can render a upshot by as early every bit calendar week eleven (for CVS) and calendar week xv (for amniocentesis).

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