How Can You Tell If It’s A Girl Or Boy On Ultrasound?

If you`ve decided to find out your baby`s gender, you`re most certainly thinking about performing an ultrasound. Normally, this ultrasound will be performed in mid-pregnancy. It`s known as a fetal anatomy survey and it`s performed to look for any fetal abnormalities, not just to find the gender of your baby.

How Can You Tell If It’s A Girl Or Boy On Ultrasound

The accuracy of this particular report will very much depend on several factors, among which the technician, the equipment used or the baby`s age. Still, there`re particular signs in the ultrasound images that a technician knows how to use to find out the baby`s gender.

How Can You Tell if It’s a Girl or Boy on Ultrasound?

When the doctor is looking for a boy on ultrasound, he`s searching for something known as the turtle sign. This is the spot where he`s able to see the penis`s tip picking out from the body. This might be difficult to see on certain babies, reason for which there is a series of signs to guide you during an ultrasound examination. The baby`s position and gestational age often play an important part in how to interpret what can be seen.

A reliable method is performing amniocentesis in order to check the chromosomes of the baby. This particular test is generally performed on a pregnant woman who is 35+ years old, with the intention of finding any possible genetic issues.

When Can You Tell the Gender of the Baby on an Ultrasound?

This is actually among the most frequent questions parents ask. Most pregnant women perform an ultrasound at about the weeks 18 – 20 of pregnancy (around 4 ½ – 5 months). Typically, at this pregnancy stage the baby`s gender can be determined; however, sometimes this may not be so. The baby`s position during the ultrasound examination is among the most essential aspects in the doctor`s ability to tell the baby`s gender, and there`s practically no way whatsoever to influence this aspect. For reasons that are obvious, it`s generally much easier to see if the baby is a boy or not.

Can an Ultrasound Be Wrong?

Ultrasound in the middle of pregnancy is often used to find out the gender of the future child by having the sonographer look for the baby`s genital organs. Now it`s the time when it will be announced, “it`s a girl!” or “It`s a boy!” Unfortunately, for certain families, this particular statement may turn out to be wrong.

Can an ultrasound examination be wrong about your baby`s gender? Of course!

How often does it happen? It`s rather hard to known and track these things as there`s not a real registry kept.

How does this happen? Here are several examples:

  • Too Early – As we already mentioned, the best time to try and determine the baby`s gender is around 18 to 20 weeks. An ultrasound examination performed earlier than this relies on the genital tubercle`s direction, and not really on external genitalia, depending on how soon the examination is made. If it`s performed after this period, it risks the part you are looking for to be too crowded as the baby develops.
  • Equipment – You probably already guessed that not all ultrasound devices are designed equally. Actually, some devices are just too old and might not offer the best views.
  • Baby Doesn`t Cooperate – Not all baby “like” to show off. There are lots of pregnant woman say their baby didn`t show off too much for the If this takes place, the determination of the baby`s gender might be made in poor pictures.
  • Experience – We have probably heard that particular joke when the baby girl is named a boy due to the fact that she had her umbilical cord between the legs. The actual truth is that an inexperienced ultrasonographer can easily make mistakes. So can an experienced one, but this would rarely happen.
  • Mother`s Weight – The things are simple! The heavier you are, the less clear is the quality of the ultrasound image. This may lead to difficulties in scanning. This in combination with other different factors might become really hard to tell the gender of the baby. The doctor might need to rely on other medical examinations.
  • Mistakes Can Happen – We can all imagine the disappointment or grief of parents who find out their dream girl or boy won`t be born, but a different gender. Many people find it very hard to recover from this. Actually, there was a small research showing that when pregnant women went through a wrong gender prediction, this lead to more than simply the distrust of an ultrasound examination. Some of them even experienced domestic violence or marital strife.

Myths on Baby Gender Prediction

Are you curious about the gender of your little tenant that rented your uterus for the next 9 months?

Even from the beginning of time, those who are about to become parents have tried to guess if the baby that they are waiting for is a girl or a boy. We`ll throw some light on 7 of the most common myths about the predication of the baby`s gender.

Heart Rate

“A heart rate of up to 140 beats per minute means that you`ll have a boy, while a hear rate of over 140 rates per minutes means that you`ll have a girl.”

Although this particular myth has circulated for decades, there`s only one scientific study to support it. In 1994, a study at the University of Kentucky has reached to the conclusion that the heart rate of the fetus can be used to correctly predict the gender of a future baby with an accuracy of almost 91% for male fetuses and 74% for female fetuses.

Any other studies made before or after this one, has reached the opposite conclusion – that the heart rate cannot be used to predict a baby`s gender.

Belly Shape

“If you wear the baby up, then it`s a girl. If you wear it down, then it`s a boy.”

If you managed to pass through the entire 9 months without anyone trying to predict the gender of your baby based on the shape of your belly, then you are lucky!

A lot of people give confidence to a myth from folklore, which claims that boys are worn down or towards the front of the belly because they need more independence, while girls are worn closer to the mother`s body because they need more protection – this is the origin of this particular myth.

Morning Sickness

“If you experience severe morning sickness, you`ll have a girl.”

Theories as this one are heard for thousands of years, but a recent study has put even more fuel on the fire.

Some Swedish researchers have discovered that 56% from pregnant women hospitalized with severe morning sickness have given birth to a girl. Even if this study seams to prove something, something which led to more than a few arguments circulated among obstetricians, the results aren`t really definitive.

Active Baby

“If the baby is very active, then you`ll have a boy.”

Here`s another theory based on some assumptions of gender, while women are more peaceful on this matter.

What this theory doesn`t take into consideration is that all fetal movements that a woman sense is a matter of perception. If she “runs” every day with various physical activities, it`s possible for her not to be able to fell more than only the strong kicks of the baby. – Learn more!


“If you crave for sweets, then you`ll have a girl. If you crave for salty, then it will be a boy.” While it may have been very convenient to figure it out if you`ll have a girl only because you crave for some chocolate, there isn`t any concrete evidence that cravings are somehow connected to the gender of your child. In reality, some people still have doubts that cravings even exist! So don`t rely on your cravings, real or not, if you want to know if you`ll need to buy pink or blue clothes.

Circular Movements

“If a wedding ring hanging over your belly moves in circle, you`ll have a girl. If it moves forward and back, you`ll have a boy.”

This particular method of predicting the gender of the child functions exact like a crystal ball. The micro-muscle tremors, over which you have no control, cause the ring to move in a certain direction – a sensation which may seem weird, but which won`t tell you anything about your future baby`s gender.

Chinese Conception Calendar

“The Chinese conception calendar may tell you if you`ll have a boy or a girl.”

The Chinese conception calendar is an idea of a scientific man from the 13th century, which pretends that can predict the gender of your future child through the connection between your age, the conception month and of your baby`s gender. If this has a pretty good reputation in China (having a pretty good accuracy), the tests performed in USA didn`t proven to be positive.

Overall Conclusion

So, if these myths fail constantly, why do we continue to revive them again and again?

According to experts, there are 2 factors which appear in these cases: the first one is that you have a 50/50 chance to be right every time you try to predict the gender of your future baby; the second one is that there are more chances to remember the successes and not the failures.

Our advice! If one of these tests will convince you to fill a wardrobe with pink dresses, be sure you can do something with them in case of failure!
