Broadcast live from the hallowed halls of the Anatomy Museum in Trinity College, Dublin, Growing Up, Live continued its fascinating deep dive into the wonders of human life by putting the perplexing facts of adulthood under a microscope.

The awe-inspiring show hit a new emotional level when a mother underwent a live ultrasound right in the heart of the Anatomy Museum and learned the gender of her new baby, along with an audience and thousands of viewers around the country. 

Professor Fionnuala McAuliffe, Head of Women’s and Child’s Health in UCD, was on hand to guide pregnant mother Aideen Lawless and her family, as well as presenter Angela Scanlon and a room of fascinated spectators through the ultrasound process, noting that it's "revolutionised the way we look after pregnancy". 

Prof McAuliffe said that about 50% of families want to find out the gender of their babies ahead of time, though in the past Irish mothers would have been suspicious of doing so. 

Using ultrasound waves, doctors can monitor many areas of development, from structure and size to blood flow and gender. Amazingly, they can even show up physical features like bigger feet or a button nose, as many parents will have seen and marveled at already. 

What many haven't seen, however, is a live gender reveal. Watch the video above to find out whether Aideen is having a little boy or a little girl! 

Growing Up, Live airs on the 13th, 14th and 15th of November at 7pm on RTÉ One.
