Guessing Fetal Sex–Gender Ultrasound

Gender Ultrasound–Guessing Fetal Sex

baby gender ultrasound

“How sure are you?” I’ve heard this question probably more than any other in my career during the baby gender ultrasound! Sometimes, guessing fetal sex is a big risk and a real guess. Patients want percentages; I just want to be right! Nothing is ever 100%!

Every sonographer is different. One’s sure is another’s iffy. I’ve seen images where a person was told one sex and the sonographer had “no doubts” only for me to scan later, confirming the opposite gender. The fact is that as long as expectant parents remain interested in guessing fetal sex by ultrasound, there will always be challenges surrounding the task.

You can see a few great images of fetal gender here. 🙂

How Sure Are We When Guessing Fetal Sex?

Are we sure or is it a guess? Honestly, they are all guesses. No sonographer should tell you her guess is 100% accurate. Even genetic tests like 1st Trimester DNA and amniocentesis can brag of 99+% accuracy! We, as humans, sure can’t surpass those odds!

Who we have making all those guesses are new sonographers right out of training, observers with little training, and those who are not formally trained in ultrasound at all (like in some of the keepsake video non-medical ultrasound business). And because reading the scan is so subjective, there will be always be incorrect guesses during the baby gender ultrasound. Even all us experienced sonographers practice a little differently. There will always be those who feel more confident to guess earlier than me. Others are more cautious, examining from every angle but still hesitant to commit if Baby’s legs are partially closed.

I’m more of the latter persuasion. I want to be VERY sure, super-duper sure before delivering a guess to my patients! I need great views in more than one angle and textbook imaging. After all, moms and grandmas want to shop! I would crawl under a rock to know I guessed incorrectly. Mostly, I would feel simply horrible for my patient, knowing it was because of me that she invested (both emotionally and financially!) in one sex vs the other! 😵😣

What’s the Answer?

Those who are new graduates or with limited experience could consult a more-experienced sonographer for a second opinion. And if a patient decides to visit an elective ultrasound business, make sure your sonographer has had formal training!

Patients should not pressure their sonographers for a percentage but also be understanding if she says she cannot determine their baby’s gender. I know! It sure stinks when this happens, but guessing fetal sex is something we can do if we have time and if Baby cooperates! Last but not least, Moms, don’t trust a fetal sex guess from anyone in a non-medical ultrasound facility that does not carry sonographer credentials! RDMS for those who are certified and DMS for those with formal training but who have not yet passed a registry examination. Experience in OB is preferable!

*And a final word of caution! Save your money during Weeks 12-14! Weeks 15-16 can still be “iffy.” Waiting until 18 Weeks and later is always better!*

The Gender Scan–Confirming Your Guess

Why Confirming Your Gender Scan Is Tough

I think most of you reading probably would believe that most of the emails I receive have to do with parents wanting me to confirm fetal sex . . . sometimes desperately so. But sometimes determining fetal sex based on someone else’s image in a gender scan I didn’t perform is an impossible task.

I try to explain in my replies that my guess is only as good as the images they send me. Some people take great images; some don’t. And sometimes, no matter how experienced a sonographer, good images are just not possible! When I explain that ultrasound is entirely subjective, this means the person performing the gender scan has total control over the images obtained. The sonographer creates these images utilizing a number of controls to optimize the image. She also uses her own discretion to determine whether she can see well enough and whether what she is seeing looks more like Team Pink versus Team Blue.

All Images Are Not Equal

Yes, there is a standard here, but I have to brutally honest. Just as people excel in some areas of life and/or profession, some are also not very good at what they do. There are good docs and bad, good nurses and bad, good cashiers and bad. This is a painfully obvious fact regarding ultrasound when I open some of these image attachments! It’s also possible these operators are not formally-educated sonographers at all! Yep, it’s true, and you can read more on the subject of elective 3D businesses here.

When we scan you real-time, we are trying to see from many angles. However, only one angle can be depicted in one image at a time. I wasn’t there during your gender scan, so I don’t know anything about the variables that could have made imaging difficult.

I just know a technically bad image when I see one. Sometimes, I can tell an operator did not take measures to improve the image. In those cases, I can only assume that someone did not know how to use them correctly. If the person scanning you is new to ultrasound or not a real sonographer, the image may not appear optimal to someone who is experienced in sonography.

Great Images for Determining Fetal Sex!

Below are some great images of fetal sex that I’ve taken myself.

The above depicts an underside view of typical-appearing female parts from about 16 – 22 Weeks pregnant.

Male genitalia, late 2nd Trimester

So, all that said, if the image you send is not an optimal one, I may not be able to take a guess on fetal sex. Even if your sonographer felt sure of her guess during the gender scan, I may not feel I can agree based on limitations of the image. That doesn’t mean your sonographer got it wrong, just that I cannot concur with the former guess because the image quality is not there. If I didn’t observe the scan myself, I am unable to see your baby’s parts from many different angles!
