After a couple has trouble having a second child, they turn to genetic screening and in vitro fertilization:
When I awoke, the embryologist relayed the excellent news: We had 20 eggs—five more than we thought possible. As soon as the April sunshine hit my face, I called my mom. Heath called his. For the first time in many months, our laughter was robust and genuine.
The next day, we learned that 16 of the eggs fertilized successfully. Even the embryologist seemed pleased. My mood lifted, despite being so sore that I couldn’t get in and out of bed on my own. Within 24 hours, we got another call: Ten embryos were progressing. From 20 chances to 10 in two day’s time; it was a pointed lesson in survival of the fittest. I’m not especially religious but I turned my head skyward, thankful we had so many miracles.
