A French physicist caught on tape the first steps of the mice fertilization process. The mechanisms to transfer the sperm DNA inside the oocyte remain largely unknown.

Mammalian fertilization, caught on tape
Using a new microfluidic device called the ‘IVF chip,’ scientists obtain the first images with both high spatial and temporal resolution of the initial steps of fertilization.
Fertilization process caught on tape for the first time
Around seventh grade, every child learns how sperm and egg meet to produce a human zygote, which will later grow into an embryo and baby. It may be a ubiquitous process, but up until now researchers have remained in the dark about the underlying mechanisms of fertilization. French biophysicists, however, have created a tool that provides highly- detailed images of what happens during the first moments of the fertilization proces.
