Almost parents today volition want to find out the sexual practice of their baby before nascency. One of the most common ways to practise this is with an ultrasound, well-nigh oft performed at betwixt 18 and twenty weeks of gestation.

According 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% "but wanted to know," and 66.8% did so "because information technology was possible."

Your Babe'south Ultrasound: What to Look

Prenatal Ultrasound

A prenatal ultrasound is a not-invasive test 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 equally it neither involves radiations nor poses harm to either the fetus or mother.

An ultrasound is routinely used at different stages of the pregnancy. While nearly practitioners will wait until at least six weeks to perform the first ultrasound, the gestational sac may exist seen as early as four and a one-half weeks, while a heartbeat may exist detected as early on equally five.

Between weeks xviii and xx, a trained sonographer will perform a detailed beefcake scan called a level ii ultrasound. It is at this time that the sonographer volition measure the size of your baby, check the major organs, measure out the level of amniotic fluid to make sure that information technology's right, and check the position of the placenta.

By this stage of fetal development, y'all should also exist able to find out the sex of your baby. While telling the difference can sometimes be tricky, there are a few things the sonographer volition await for to brand the determination.

Accurateness

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

With that being said, over 99% of ultrasounds performed between weeks 18 and 20 will make the right decision. Information technology is but when it is performed before week 14 that the charge per unit of accuracy tin driblet significantly.

According to a 2014 study from Australia, which reviewed 642 fetal ultrasound results performed between weeks 11 and 14, the overall success rate in determining fetal sex activity was 75%. The near common mistake was to assign male person fetuses as female.

Girl Ultrasound Signs

When determining the sex of the fetus on ultrasound, the sonographer will look for characteristic features known as signs. For girls, in that location 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 prototype, you lot volition 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. Information technology is obtained by looking at a profile view of the fetus (known as the midline sagittal plane). There is a nub at the stop of the spine, called the caudal notch. If it is pointing downwardly at a 10-degree angle, then the fetus is a girl.

Boy Ultrasound Signs

You lot would recollect that male fetuses would exist easier to identify than females, but that's not always the instance. This is especially true before calendar week 14. By weeks 18 to 20, the determination for a baby boy would be based on the following signs:

• Sagittal sign: If the caudal notch is pointing upward at more than a thirty-degree angle, and so the fetus is a male child. If information technology is somewhere in between, it may be harder to make a definitive determination.
• Flow of urine: The flow of urine tin can sometimes be spotted in a fetus. If it is moving upwards, and then it is more likely a boy.
• Male person genitalia: Often exist seen by weeks 18 to twenty, the presence of male ballocks, including testicles, scrotum, and penis, is a clear sign of male gender.

Other Ways to Determine Sex

In addition to an ultrasound, the sex activity of your baby tin 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 decision and can return a outcome by as early on every bit week 11 (for CVS) and 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 sex later on an amniocentesis compared to 28% who preferred an ultrasound. This was despite the fact that 96.2% of women believed that an ultrasound was a reliable means of determining the sex of her baby.
