Egg Cells Spark With Light When Penetrated by Sperm

Conception has never looked cooler, with egg cells appearing to spark with light when penetrated by sperm.

Egg cells appear to flash upon penetration by sperm

“We discovered the zinc spark just five years ago in the mouse, and to see the zinc radiate out in a burst from each human egg was breathtaking,” says one of the reasearchers Teresa Woodruff.

Although  according to US law it is illegal to fertilize a human egg cell(s) with sperm for research purposes, the event was replicated using sperm enzymes instead (without the actual sperm). A camera microscope was used to film and capture the event.

Egg cells appear to flash upon penetration by sperm, triggering the rise of calcium levels inside the egg which prompts the release of zinc. It is this zinc which binds to molecules to emit a ‘spark’ or fluorescence, seen through camera microscopes.
