We are proud to have the passion and the skill set it takes at determining gender from just 12 weeks.

  If you are impatiently counting down the days until your 18- to 22-week anatomy scan then you are at the right place. 

The nub theory has been one of the most talked about topics across the internet for many years! 

If you have had your NHS dating scan then hopefully your little one has showed off  their nub, then this is where our skills come in. 

Nub theory isn't  just a "theory" as many seem to think, you simply can not argue the fact that the nub (genital tubercle)  is your baby's developing genitalia. During the 12th week of pregnancy your baby's nub is rapidly changing, soon it will find its final resting place and develop in to clitoris and labia or penis and scrotum.


Honesty is our policy, we are here to be able to offer you this early insight in to your baby's gender, that little glimpse into the womb 6-8 weeks earlier than usual

If we are not confident we will not predict and a full refund will be issued. 

Fetal gender assessment by ultrasound was prospectively carried out in 172 singleton pregnancies at 11–14 weeks of gestation. The genital region was examined in a mid-sagittal plane, and the fetal gender was assigned, for

 male fetuses if the angle of the nub was angled greater than 30° then he was a boy, and in female fetuses if the nub was parallel  (less than 30°) to the horizontal line then she is a little girl.

We absolutely believe in the methods we use, we have the best experience possible along with  years of extensive training, this makes us the most reliable source for early gender prediction.
