We invite you to a fascinating journey through the creation of human life with these spectacular images of conception and pregnancy week by week. We can see the first moments since the egg is fertilized through the early stages of embryo formation until the last weeks of pregnancy.
The photographs were taken over 12 years by the famous Swedish photographer Lennart Nilsson using an endoscope complemented with those of The Multi-Dimensional Human Embryo project with three-dimensional images recreated from magnetic resonance images.
