This is the most extreme competition on Earth - a competition with 250 million participants, only one winner, and ruthless obstacles. The Sperm Race "tells the story of human conception by enlarging human sperm to human size through live action. This is an extraordinary journey of sperm showcased by cameras never before installed by helicopters, world-renowned scientists, CGI, and dramatic reconstructions. As the microscopic world of sperm and eggs magnifies precisely 34000 times, we see human sized heroes weaving through the world's most striking landscapes, the epic proportions of the vagina turning into the Canadian Rocky Mountains, and the architecture on London's South Bank symbolizing the complexity of the cervix. Due to the fact that women's bodies are designed to repel and destroy invaders, sperm face relentless obstacles from acidic vaginal walls to impassable cervical crypts Dr. Allen Pesci explained, "The struggle of sperm to find an egg and fertilize it is enormous. Everything is detrimental to sperm, and the female reproductive tract does not truly lend a helping hand Large areas will die, and only one can achieve the ultimate goal - egg fertilization and the beginning of new life. The Great Sperm Race "is jointly produced with the Wellcome Trust and consulted with world leading reproductive scientists, showcasing the extraordinary complexity of our bodies and the enormous lottery of luck in our reproductive process.
