Couples are having kids much later in their lives. As young people spend more of their 20s and 30s getting established in their careers, and marriage is delayed, and home buying is delayed, the unstoppable force of delay runs up against the immovable object of human anatomy. It is harder for a 40-year-old to get pregnant than for a 20-year-old to do so. The best solution we have for the fertility dilemma of the modern age is in vitro fertilization. IVF is a decades-long practice based on science, so you might think that the procedure is highly predictable, something close to an act of precision engineering. But people who have gone through the process know it can be messy, painful, frustrating, and expensive. So, what would a real scientific revolution in fertility look like? How close are we to a game-changing invention in this space? Today’s guest is Ruxandra Teslo, a scientist and writer. We talk about the fertility dilemma that exists, the fertility technology that doesn’t exist, and how a revolution in egg science could produce a second baby boom.
