Potty Shot Ultrasound — What Do 3 Lines Mean on Ultrasound?

In the world of prenatal ultrasounds, expectant parents are eager to see the first images of their growing baby. One particular type of ultrasound, known as the potty shot, is getting significant attention. Many parents-to-be are curious about this ultrasound type but may also be confused. If you’re one of them, you’re in the right place!

So, what exactly is a potty shot, and what does it mean when you see the 3 lines during the examination? In this blog post, we’ll dive into the potty shot ultrasound and explain the meaning behind them. So, if you've ever wondered about the significance of those three lines —  let's clear it up once and for all!

Potty Shot Ultrasound — A Complete Guide

Potty shot ultrasounds are also known as sex determination ultrasounds. These ultrasounds are the most important moment for parents who are eager to find out the sex of their unborn baby. During the ultrasound, parents can see the baby’s genitals and, with that, discover the sex of the baby. In this step-by-step guide, we’ll explain everything you need to know about potty shot ultrasounds. 

1. Understanding the Potty Shot

Potty shot ultrasounds are specialised scans performed during pregnancy to determine the baby's sex. They capture images of the genital area, focusing on forming the baby’s external reproductive organs.

2. When Is It Conducted?

Potty shot ultrasounds are typically performed between the 18th and 22nd weeks of pregnancy. This timeframe is considered ideal because the baby's genitals have developed sufficiently for accurate sex determination, yet the baby is not too large or too small to obtain clear images.

3. How It's Conducted?

During the ultrasound, the expectant mom lies on an examination table. Then, the sonographer (the person conducting the ultrasound) applies a gel to the belly, which helps with sound wave transmission. After that, a handheld device called a transducer is used to emit high-frequency sound waves. This device is what creates the images of the baby’s internal structures, including the genitals. The sonographer examines the images to identify the baby’s sex. 

4. Accuracy of Potty Shot Ultrasounds

Potty shot ultrasounds are generally considered accurate. The success rate in determining the baby's gender moves between 95% and 99%. But it’s important to note that factors like foetal positioning, the sonographer's skill, and the ultrasound's timing can influence accuracy.

5. Preparing for the Potty Shot Ultrasound

Before the ultrasound, pregnant women should drink plenty of water. The reason is the fact that a full bladder can aid in obtaining clearer ultrasound images. It’s also important to wear comfortable clothes that can be easily lifted or removed. Moms, keep in mind that you will need to expose your belly for the ultrasound!

What Do 3 Lines Mean On Ultrasound?

The three lines on a potty shot ultrasound are an important indicator of the baby’s sex, specifically suggesting that they are a female. This ultrasound finding is known as the three-line sign or hamburger sign because the three parallel lines look like a stacked, juicy burger!

Let’s look into what each of the lines represents!

• Top Line: The top line represents a female foetus's clitoral hood or prepuce. It is the protective covering for the clitoris.
• Middle Line: The middle line is the actual clitoris, a small, sensitive organ.
• Bottom Line: The bottom line corresponds to the labia minora, which are the inner folds of skin surrounding the vaginal opening.

When a sonographer sees these three lines on the ultrasound, it strongly indicates that the baby is a girl. However, you should always remember that ultrasound results can vary depending on various factors. While this sign is very reliable, it's not foolproof. We mean to say there’s still a chance that the baby is not a girl, even if you see the sign!

12 Week Potty Shot Accuracy

A potty shot done at 12 weeks of pregnancy is a part of the first-trimester screening or Nuchal Translucency (NT) scan. This ultrasound can provide valuable information about the baby's development, but it has limitations, especially regarding gender determination.

The two main considerations when it comes to the 12-week potty shot accuracy are:

1. Gender Determination: At 12 weeks, the genitalia of the baby are still developing. So, the genital organs may not be fully formed or distinguishable on an ultrasound. The accuracy of gender determination during this early stage can be quite low. At this stage, the accuracy ranges from 50% to 70% or even lower. 

2. Foetal Position: The accuracy of any ultrasound, including potty shots, depends on the baby’s position. If the foetus is in an unfavourable position, it can be difficult to get clear images of the genital area.

To sum it up, we can tell you that a 12-week potty shot can give you an early glimpse of your baby's development. But at this stage, this is not the most reliable method for determining sex accuracy. If you want to be certain about your baby's gender, it’s best to wait. You can have a more detailed ultrasound later, in the second trimester. It's important to remember that the primary purpose of the 12-week ultrasound is to assess the baby's overall health. With this ultrasound, sonographers also screen for chromosomal abnormalities, and that’s far more important!

Potty Shot at 16 Weeks — What Does It Mean?

The ultrasound done at 16 weeks is a whole different story from the potty shot at 12 weeks because it can provide more reliable information about the baby's sex compared to earlier scans.  

Here's what to expect from the potty shot at 16 weeks!

1. Sex Determination: At 16 weeks, the genitalia of the baby have had more time to develop. Naturally, they’ll be more visible on the ultrasound. A potty shot at this stage is often conducted to determine the baby's sex. If the ultrasound technician can see the genital area and identify either male or female characteristics, they can tell you the baby's gender.
2. Accuracy: The accuracy of sex determination at 16 weeks is quite high, even going up to 95%!  But do remember that no method is 100% foolproof, and there is still a small margin for error.
3. Foetal Position: The success of a potty shot ultrasound, like any ultrasound, can be influenced by the baby's position. If the baby is not in an ideal position for imaging, it may be challenging to obtain clear views of the genital area.

In short, a potty shot ultrasound at 16 weeks is used to determine the baby's sex with better accuracy. Gender determination at 16 weeks may not be 100% guaranteed, but it is more accurate than scans in the earlier stages of pregnancy. If you're eager to know your baby's gender, this is an excellent time to consider a potty shot ultrasound. Also, it’s a great opportunity to talk to your doctor and discuss any questions or concerns.

Final Remarks on Potty Shot Ultrasounds

The potty shot ultrasound is one of the most exciting things in the prenatal phase of your pregnancy. These scans offer a glimpse into your baby's gender but also serve as a reminder of the miracle of life. While the accuracy of gender determination can vary depending on the timing of the ultrasound and the baby's position, potty shots at the right time can provide spot-on results. 

Remember, the primary purpose of prenatal ultrasounds is to monitor the health and development of your baby. So, whether you choose to learn your baby's gender early or wait for a later scan, potty shots are a must!
