We've all been told the story about the birds and the bees. But thanks to a recent medical study, researchers now have the capability to identify the exact moment when conception takes place.

For the first time, researchers have witnessed the exact moment conception occurs, and have recorded the ensuing explosion of sparks that form when sperm meets an egg. According to the Telegraph, scientists had previously captured the moment in animals, but this is the first time it's been recorded in humans.

By looking at the size and quality of the zinc spark, researchers could know immediately which eggs are ideal to transfer during in vitro fertilization. 

Researchers who analyzed a video of nine human eggs touching the sperm observed that two flashed brighter than the others, insight that could provide an important tool for doctors trying to determine which fertilized eggs to choose during IVF..

Researchers noted that some of the eggs burn brighter than others, which may indicate they are more likely to develop into a healthy fetus. This could provide a non-invasive, easily visible way to assess the health of an egg.

The study was published in the journal Scientific Reports.
