Pro-life couple uses "leftover" IVF embryos

E.
I saw this article on Facebook and thought it was interesting. 
While I myself am pro-choice, it's nice to see a pro-life couple advocating for babies after birth, and not just until birth. 
Although, I thought the concept of using someone else's leftover frozen embryos was a bit strange. I had never heard of that before. Apparently their pro-life stance extends to embryos leftover from <a href="https://glowing.com/glow-fertility-program">IVF</a>. 
I was having trouble copying & pasting the article, so here are pictures of a few excerpts, hope you can read them:
