The "3 Lines" Explained (Potty Shot) not just for girls
Its a very common misconception that only girls image with 3 lines in their potty shot or gender scans. I want to take the time to explain that is ABSOLUTELY NOT TRUE
BOTH genders can image with three lines!!
The biggest miscommunication is between doctors and their patients during the gender scan And this has then spread
To be honest, when I was pregnant with my 1st daughter, I was told by the doctor "Oh look, theres 3 lines, you're having a girl" and at the time I also believed that only girls imaged as 3 lines.
After being in several gender prediction groups, and creating my own group/page and doing tons of research I realized that almost every woman believes this false statement.
Why do the genitals image as lines?
because ultrasound images as lines!
Anything rounded can image with lines meaning labia, clitoris and even the head of the penis can image as lines. Here is an example of how both genders can image as 3 lines:
So if both genders can image as 3 lines, how do you tell them apart?
This is were the femur comes into play!! If the baby is a boy the genitals will protrude further down the femur and in most cases the middle line is longer than the 2 on the sides. If the 3 lines are even with the end of femur and in some cases the middle line is inverted, baby is most likely a girl!!
Another identifier could possibly be the bladder within the potty shot. The bladder can only be seen in a boys potty shot do to their low bladder position and their genitals being on top of their lower abdomen. The bladder images as a black circle under the penis and scrotum and to an untrained eye may look like the anus. It cannot always be seen in boys potty shots but will never image in a girls due to their genitals being in front of the bladder from that view. Examples:
Both genders can also image as "3 dots". If the dots are all in a row, the baby is most likely a girl and what is being seen is labia and clitoris. If one dot images on top of the other 2 baby is most likely a boy and top dot is penis and the two underneath are testes.
This is a BABY BOY: Red arrow indicating penis and yellow arrows indicating testes.
Both (above and below) images show boy genitals imaging as 3 dots that protrude down the femur. As seen in the image below, 3 dots are visible, indicating penis & testes, bladder is shown (black circle under genitals). This baby is also a BOY!
This is a BABY GIRL:
In the image above the 3 dots are all in a row indicating labia and clitoris! In the image below is another baby girl imaging with 3 dots. Both images showing girl genitals even with the end of the femur.
Hopefully this clears up some of the misunderstanding about the 3 lines statement!
