The Nub Theory
In our comment section, we found that people are very curious to find the baby’s gender before birth. To calculate fetus gender, they are discussing various theories like old wives tales, Chinese gender prediction calendar, Ramzi theory, baking soda gender test, and some local methods but all of these methods have no scientific and medical base and have a 50/50 chance of having baby boy or girl.
Non-Invasive Prenatal blood Testing (NIPT)
The authentic ways to know the fetus’s gender includes 10 weeks pregnancy Non-Invasive Prenatal blood Testing (NIPT), which measures the cell-free fetal DNA in pregnant women’s blood serum to find various genetic abnormalities. In addition, NIPT can also be used to find a baby’s gender more precisely.
Anomaly Scan Ultrasound
The fetus’s gender can also be determined more accurately during 20 weeks pregnancy ultrasound (anomaly scan). Gender scans or gender sonograms performed at pregnancy week 18 to 24 are more accurate than 2d ultrasound 14 week or 16 weeks pregnant ultrasound.
Nuchal Translucency Ultrasound Scan (NT)
A nuchal translucency ultrasound scan (NT), performed at weeks 11 to 13 to measure fluid-filled behind the baby’s neck for Down syndrome abnormalities can also be used to find the baby’s gender with genital tubercle also known as a nub.
In-Vitro Fertilization
Can you pick the gender with IVF? Yes, sex selection is possible with gender selective IVF or ICSI gender selection. Gender selection IVF is a process of selecting the genetic sex of the coming baby as a boy or girl, by testing the embryo’s anatomy through the IVF process before implanting it in the mother’s uterus. IVF and gender selection process is completed in a special IVF clinic (in-vitro gender selection fertility clinic) through a series of hormone injections, egg retrieval, sperm sorting, egg and sperm matching, and at the last embryo implantation.
We find people asking questions like what is nub, how does nub theory work, how accurate is the nub theory, Does nub theory at week 13 works, and can you see gender at 12 week. We will explain all about the nub and skull theory in this nub theory for the gender article.
What is nub?
Before the 14 weeks pregnancy, a baby boy or girl fetus looks identical having an anatomical lump on the lower abdomen of the fetus between legs called the genital tubercle also a “nub”, which will later turn into specific sex organs of a boy and girl i.e nub will grow into the penis for baby boy and clitoris for baby girl.
The Nub Gender Theory
The genital parts of a baby grow between the pregnancy weeks 7 and 12, but the penis and clitoris have the same shape until around week 14, which makes distinguishing between the two at that period very difficult. According to nub theory, if the angle of the dangle or fetus nub along the spinal cord is 30 degrees upward or more in a clear view ultrasound full image of the crown to ramp taken between 11 and 14 weeks, then the fetus will be a boy, but if the fetus spine and the nub angle is less than 30 degree or both are parallel to each other, then the fetus will be a baby girl.

How accurate is the nub theory
Studies show that the accuracy of gender prediction using nub theory increases gradually with the gestational age. At the 11-week ultrasound, the nub theory is 65% accurate; 12 weeks pregnant ultrasound has 73% accuracy; 13 week ultrasound reports indicate 85%, and 14 week ultrasound scan results are precise up to 98%. The use of nub theory for gender prediction is getting fame in pregnant women, but nub theory 9 weeks pregnancy or nub theory 8 weeks has a low accuracy rate. The size and development of a baby play an important role in the accuracy of gender identification.
What does it mean to have a forked nub?
The length and form of your baby's nub can sometimes, but not always, predict sex. Some people believe that a "forked nub" is suggestive of a female fetus, however, we disagree because a forked nub may be observed in both males and females in the initial phases of development.
What is the earliest time that the nub theory may be applied?
The Nub Theory states that the angle of the genital tubercle in reference to the fetal spine may be utilized to predict whether a baby is a boy or a girl during precise ultrasound measures made around 12 and 14 weeks of gestation. At what period of gestation can the nub theory be applied? The simple answer is, that the earliest time the nub theory may be applied is at 12 weeks of gestation.
12-week nub change?
The viability of the nub theory is contingent on whether or not we are observing the nub in its entire form and during gestation. At 12 weeks, there is a possibility that a female appearing nub would rise, but at 13 weeks, it most likely won't. Since nubs typically rise, you should transition from a nub that is more girly to a nub that appears more boyish. But, if there was a segment of the nub that we couldn't get in a scanned shot or if there was something hiding the nub, an estimate might be wrong and thus shift of gender from a boy to a girl is possible. Nubs didn’t drip and convert from a boy to a girl.
How do you distinguish if it’s a nub?
Your kid has to be resting on its side, not cradled, and in a flat position in order for you to view the nub. Up to 14 or 15-week ultrasound tests, the female and male genitalia just seem too similar to discern between the two with absolute certainty. If a result is provided prior to this stage, there is a possibility that it will not be accurate.
Before sexual body parts are fully matured, it is quite difficult to determine whether they are projecting from the body or located within. In light of this, it is preferable to exercise patience and wait until the right scan is performed. When you are trying to determine the sex of your kid, keep in mind that the utmost essential thing is that they are in fine fettle.
What does a girl nub look like at 13 weeks?
You could be having a girl if her nub is facing downward to the bottom, for an angle of lesser than 30 degrees in respect to its spine. So, this little girl is most likely female due to the fact that she contains a genitalia nub aligned more horizontally, parallel to the spine.
What week does the gender develop?
Because it generates a picture of the baby, a sonogram may also tell you what your baby's gender is going to be. The majority of physicians perform ultrasonography between the stages of 18 and 21 weeks of pregnancy; however, sonography may identify the gender of the baby as earlier as 14 weeks.
At 20 weeks gestation, is it possible to confuse a girl for a boy?
We are more likely to make inaccurate predictions about boys than about girls. This could occur, for instance, if the baby is growing slow and the nub hasn't started to tape up yet, or if the umbilical cord is confused for a penile. There is still a possibility that the gender determination will be incorrect, despite the fact that it is far highly accurate with the 20-week sonography.
