So apparently scientists have discovered that at the moment of fertilization the sperm and egg create fireworks (zinc sparks)! Aside from being a pretty cool graphic, there seems to be something so poetic about the whole thing. As this article points out, the hope is that can lead to better IVF success rates if scientists can measure the strength of the sparks to determine the viability of the embryo (essentially doing away with the need for waiting to transfer an embryo).
Of course, what does that mean for donor eggs and sperm? If my sister donates her eggs then theoretically my sister’s donor egg will spark with my husbands sperm. So my sister and my husband will have created fireworks.
I shall try not to think about that and just enjoy the GIF.
