I recently found this nicely animated video on In Vitro Fertilization created on the new TED-Ed platform. You might find this a good way to not only inform yourself but also friends and family who might have trouble understanding the fertilization process.
"Infertility affects 1 in 8 couples worldwide. But in the last 40 years, more than 5 million babies have been born using in vitro fertilization (IVF). How does it work? Nassim Assefi and Brian A. Levine detail the science behind making a baby in a lab."
Lesson by Nassim Assefi and Brian A. Levine, animation by Kozmonot Animation Studio.
