WATCH: This amazing video shows what REALLY happens during IVF

Ever since the birth of the first ever "test tube baby", Louise Brown in 1978, in vitro fertilisation (IVF) has given hope to millions of couples all over the world. 

In the last 40 years alone, more than five million babies have been born using the sophisticated procedure, a process by which an egg is fertilised by sperm outside the body: in vitro ("in glass").

While it might be commonplace these days (one in eight couples experience infertility, after all), unless you've been through it, it can be difficult to fully understand IVF; a reason why, as part of a Ted Ed original, Nassim Assefi and Brian A. Levine decided to detail the science behind making a baby in a lab.

With animation by Kozmonot Animation Studio, this truly beautiful video takes the viewer through the process from beginning to end in an eye-opening celebration of one of the most amazing human journeys.
