Most parents today will desire to find out the sexual activity of their baby before nascency. One of the well-nigh mutual ways to do this is with an ultrasound, about often performed at between 18 and 20 weeks of gestation.

Co-ordinate to a 2012 study published in the periodical 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% "only wanted to know," and 66.8% did so "because information technology was possible."

Your Baby's Ultrasound: What to Expect

Prenatal Ultrasound

A prenatal ultrasound is a non-invasive test that uses audible audio 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 dissimilar stages of the pregnancy. While almost practitioners will wait until at least half-dozen weeks to perform the offset ultrasound, the gestational sac may be seen as early as four and a one-half weeks, while a heartbeat may be detected every bit early on as v.

Between weeks 18 and 20, a trained sonographer will perform a detailed anatomy scan called a level 2 ultrasound. It is at this fourth dimension that the sonographer will measure the size of your infant, check the major organs, measure the level of amniotic fluid to make certain that it's right, and bank check the position of the placenta.

Past this stage of fetal development, you should besides exist able to find out the sex of your baby. While telling the divergence can sometimes exist tricky, there are a few things the sonographer volition look for to make the determination.

Accuracy

When a sonographer does a level 2 exam, what is seen on ultrasound is far more than important than what is not seen. With regards to determining sexual practice, what this means is that the absence of a penis does non inherently mean that you lot accept a girl.

With that existence said, over 99% of ultrasounds performed between weeks xviii and 20 will brand the correct determination. Information technology is but when it is performed before week xiv that the rate of accuracy can drib significantly.

According to a 2014 study from Commonwealth of australia, which reviewed 642 fetal ultrasound results performed between weeks eleven and 14, the overall success rate in determining fetal sex was 75%. The most common error was to assign male person fetuses equally female.

Girl Ultrasound Signs

When determining the sex of the fetus on ultrasound, the sonographer will await for characteristic 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 volition run into 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 equally the midline sagittal plane). There is a nub at the cease of the spine, called the caudal notch. If it is pointing downward at a 10-degree bending, and so the fetus is a daughter.

Male child Ultrasound Signs

You would think that male fetuses would be easier to place than females, only that'southward not e'er the case. This is especially true before week fourteen. By weeks xviii to 20, the conclusion for a baby boy would be based on the post-obit signs:

• Sagittal sign: If the caudal notch is pointing upward at more than a 30-degree bending, then the fetus is a boy. If it is somewhere in between, it may be harder to make a definitive conclusion.
• Flow of urine: The menstruation of urine can sometimes be spotted in a fetus. If it is moving upward, so information technology is more likely a boy.
• Male genitalia: Often exist seen by weeks xviii to 20, the presence of male person genitalia, including testicles, scrotum, and penis, is a clear sign of male gender.

Other Means to Decide Sex activity

In improver to an ultrasound, the sex 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 authentic in making the determination and can return a consequence by as early as week 11 (for CVS) and week 15 (for amniocentesis).

In fact, the same study published in Obstetrics and Gynecology ended that 65% of parents preferred to know the infant'southward sex after 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 ways of determining the sex of her baby.
