“We just needed to figure out how to have everything in a very confined space.”

Two babies in South Africa were born from IVF performed in a trailer packed with lab equipment and air filters, part of the Walking Egg project aimed at rural low-income areas. South Africa has fewer than 30 fertility clinics for 60 million people. Countries like Angola and Malawi have zero. One in six adults worldwide experience infertility, and the rates are similar in rich and poor countries, but only rich countries have the infrastructure to do anything about it. This is the kind of practical, unsexy medical innovation that actually changes lives.
