Most parents today volition want to find out the sexual activity of their baby before birth. One of the most common ways to exercise this is with an ultrasound, virtually oftentimes performed at between 18 and 20 weeks of gestation.

Co-ordinate to a 2012 written 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% "just wanted to know," and 66.8% did so "because it was possible."

Your Baby's Ultrasound: What to Expect

Prenatal Ultrasound

A prenatal ultrasound is a not-invasive test that uses audible sound waves to produce images of a fetus's shape and position in the uterus. It is a preferred method of imaging during pregnancy as it 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 volition wait until at least six weeks to perform the first ultrasound, the gestational sac may be seen as early on as four and a half weeks, while a heartbeat may be detected as early as 5.

Between weeks 18 and 20, 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, cheque the major organs, measure the level of amniotic fluid to brand sure that information technology'southward right, and cheque the position of the placenta.

Past this phase of fetal development, you should also be able to find out the sexual activity of your baby. While telling the difference tin can sometimes be tricky, there are a few things the sonographer will look for to make the determination.

Accuracy

When a sonographer does a level 2 exam, what is seen on ultrasound is far more of import 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 beingness said, over 99% of ultrasounds performed between weeks eighteen and 20 will brand the correct determination. It is only when it is performed before week fourteen that the rate of accuracy can drib significantly.

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

Daughter Ultrasound Signs

When determining the sex of the fetus on ultrasound, the sonographer will look for characteristic features known equally signs. For girls, in that location are ii signs to look for:

• Hamburger sign: This is the moniker given to the appearance of the labia and clitoris on an ultrasound. If you lot expect closely at the prototype, you lot will encounter that the labia lips would look similar to a hamburger bun, while the clitoris would resemble the hamburger patty.
• Sagittal sign: Each sexual practice has a sagittal sign. It is obtained past looking at a profile view of the fetus (known as the midline sagittal plane). There is a nub at the terminate of the spine, called the caudal notch. If it is pointing downward at a 10-degree bending, then the fetus is a daughter.

Male child Ultrasound Signs

You would think that male fetuses would be easier to identify than females, but that's not ever the case. This is especially true before week 14. By weeks 18 to xx, 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 30-degree angle, and then 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 tin sometimes be spotted in a fetus. If it is moving upward, then it is more likely a boy.
• Male genitalia: Frequently be seen by weeks 18 to 20, the presence of male person genitalia, including testicles, scrotum, and penis, is a clear sign of male gender.

Other Means to Determine Sexual activity

In add-on to an ultrasound, the sex activity of your baby 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 conduct risks, they are extremely accurate in making the determination and can return a result past as early on as 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'south sex afterward 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 infant.
