The following submission statement was provided by /u/genericdude999:

> When looking for donors, the Ridgeways specifically asked the donation center about a category called “special consideration,” meaning it had been hard to find recipients for these embryos, for whatever reason.

> To pick their embryos, they went through a donor database. It did not list the how long embryos have been frozen, but it listed the donors’ characteristics like ethnicity, age, height, weight, genetic and health history, education, occupation, favorite movies and music. With some files, there are photos of the parents and of their children if they have them.

> The Ridgeways assumed those listed with earlier donor numbers had been at the center the longest and tried to narrow their choice to those profiles.

> The embryos were created for an anonymous married couple using in-vitro fertilization. The husband was in his early 50s, and they used a 34-year-old egg donor.
