Submitting your scan couldn't be easier.

​

Simply purchase your chosen package, then follow the instructions on the following pages where you will also be able to upload your images and videos. Please include your baby's exact gestational age on the day of the scan, along with any additional information you think may be helpful.

​

The more suitable images and videos you provide, the more accurate our assessment will be.

*Understanding development during the first trimester

​

We begin assessing scans from 12+0 weeks, as this is the earliest stage at which nub theory can be applied.

​

At this stage, both male and female genitalia are still developing. The genital tubercle (nub) continues to mature throughout the first trimester, with development becoming complete at around 14 weeks, when fully formed external genitalia are present and nub theory no longer applies.

​

Female genital development generally follows a more consistent pattern. The genital tubercle typically remains elongated and tubular as it develops into the clitoris, meaning its appearance changes relatively little during this period.

​

Male genital development, however, often undergoes more noticeable changes between 12 and 14 weeks. A male baby's nub may initially appear very similar to a typical female nub before gradually developing into the penis and scrotum. This means that some boys, particularly at 12+0 weeks, can display a female appearing nub, with the differences becoming increasingly apparent as gestation progresses.

​

Based on the trends we have observed from analysing hundreds of thousands of scans over almost 20 years, approximately 20% of babies who display a typical female appearing nub at exactly 12+0 weeks later develop obvious male characteristics. This is one of the reasons predictions made at the earliest gestations naturally carry a lower confidence than those performed later in the first trimester.

​

Our overall historical accuracy exceeds 99% across all suitable predictions. However, every report also includes an individual confidence rating, which reflects how confidently we can interpret your specific scan based on gestational age, scan quality, foetal position, anatomy and visibility.

​

If your scan receives an 80% confidence rating, this simply reflects that your baby is at the earliest stage of assessment or that other factors limit certainty. While an 80% confidence prediction is still a prediction we are happy to stand behind, it also means there remains a greater possibility that your baby's appearance may change as development progresses.

​

While many 12 week scans achieve higher confidence ratings, the earliest gestations can occasionally receive a lower confidence score. If you would prefer to avoid this possibility, we recommend waiting until a later gestation before submitting your scan.
