Discover the thrilling story of how you were made, from the moment of conception to the moment of birth 280 days later. This breakthrough series follows the gestation process, using state-of-the-art CGI to reveal the most exquisite biological choreography found in nature. Across three episodes we chart how 100 trillion cells come together to make each of us a unique individual.

Episode two continues to follow the incredible journey focusing on the middle months of our time in the womb when we become unique individuals. For the first ten weeks of pregnancy our biological sex is hidden. Meet the remarkable village of people in the Dominican Republic where the sex determination process in the womb doesn’t always run to plan. Testosterone also influences the mind, which Michael sees when he meets a family in California, whose daughter, seven-year-old Mati, feels she has been born in the wrong body. Occasionally, our cells do not always follow the plan, like with baby Oliver, one of the 1 in 1000 babies who arrive with a cleft lip; or Cheryl, a member of just a handful of families in the world who have no fingerprints; and Jo, who is searching for her immune system twin as her best hope to overcome leukemia.

Episode three journeys through the final months in the womb — a time when we grow strong and develop our vital survival tools for our first breath. For most, this is when our cartilage changes to form a skeleton of over 200 bones, but very occasionally it doesn’t. Meet Jannelly, who was born with no bones and was saved from the brink of death by a drug trial, which made medical history by creating “manufactured bone” for the first time. Our brains develop at an extraordinary rate by week 27, with an estimated 100 billion new connections every day, creating the foundations for our memory banks. This happens at a time when the unborn baby is beginning to hear and it could just be that early attempts at memory and recall might begin around this time, inside the womb. Indeed, external forces can affect us in the womb in many ways. We survey the very latest in epigenetic research which shows how the womb environment leaves its mark, maybe even altering your DNA.
