Okay, people, don’t get so excited. Read the full article, it explains what is happening in the video.
The video was using a sperm protein, not an intact sperm, to cause the reaction. None of the eggs were actually fertilized. The light was caused by a release of zinc from the egg, which interacted with a fluorescent dye to create the flash of light. The egg itself did not light up, and eggs being fertilized do not emit a flash of light.
The fact is that fertilization is not some magical event. It is merely the fusion of two living cells. When the sperm fuses with the surface of the egg, it injects its DNA into the egg. The DNA then travels to the nucleus of the egg, and then is matched up with the DNA in the egg. Once the DNA is matched up, then the egg can start dividing and might grow into an embryo. This process is highly error-prone: most fertilized eggs do not grow, and even when they do undergo a few cell divisions, they do not become embryos. A large fraction of the eggs that do become embryos are incapable of developing very far, and die early (aka miscarry). Between the eggs that never become embryos and the third of embryos that die early on, the chance that a specific egg being fertilized will lead to the live birth of a baby is somewhere between 10% and 15%.
That’s what I picked up on too.
In the experiment, scientists use sperm enzyme rather than actual sperm to show what happens at the moment of conception.
In other words...you are not likely to have been born, and now more likely to be aborted than ever. So, every life kinda almost is sort of precious. Hmm.
