Zinc And IVF - the flash of light at the very moment a sperm cell makes contact with an egg.

Scientists Just Captured The Flash of Light That Sparks When a Sperm Meets an Egg. For the first time ever, scientists have captured images of the flash of light that sparks at the very moment a human sperm cell makes contact with an egg. The phenomenon has been observed in animals before, but no one’s ever seen the spark of human conception. And what’s even more incredible is the fact that some eggs burn brighter than others, which is a direct indication of their ability to develop into a healthy embryo, a team from Northwestern University found. “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.“ If you follow health science news closely, you’ll know that the vast majority of studies - even the most promising ones - fail to live up to their potential. Maybe positive results in mice didn’t translate in
