From Fertilization to Birth: Watch It Happen (GIF)

It’s time we had the talk. Sure, you know about where babies come from, but do you know how the whole thing actually works? We finally have a great visual to show you the ins and outs of embryogenesis — the process of of egg fertilization and fetal development.

Seattle-based designer Eleanor Lutz created this blow-us-away GIF of the fertilization process, beginning with a depiction of a fertilized egg before it breaks down into a multi-celled organism. Watch it become a recognizable fetus, following everything from blastocyst formation at position G to fetal eyelid development at E1. Basically, this alphabetized breakdown of fetal development is the biology class refresher all moms-to-be need. Well, our pregnancy app is a close second.
