A beautiful educational musical video based on Billy Joel's "We Didn't Stop the Fire", explaining the process from conception to childbirth. It is made for MU med school class of 2010. The lyrics is below.

The video is educational and yet very entertaining.

Mom and dad, empty pad, there’s time, prophylactic’s bad
Sperm are swimming, egg is going, fertilization

Week one, zygote there, dividing here, there, everywhere
Two, four, eight, sixteen, that’s the morula

Zona pellucida, shed from early blastocyst
Late blastocyst now, trophoblast and blastocoele

Trophoblast splits into inner cytotrophoblast
Synctiotrophoblast, outer shell, implanting

CHORUS
We didn’t stop the fetus
It keeps on developing, inside mom’s belly
We didn’t stop the fetus
Since we did create it, we are going to wait for it…
