Ovaries. Most women have two; journalist Natalie Lampert has only one. Then, in her early twenties, she almost lost it, along with her ability to ever have biological children. Doctors urged her to freeze her eggs. This is the story of Lampert's personal quest to investigate egg freezing as well as the multibillion-dollar femtech industry, in order to decide the best way to preserve her own fertility. She attended flashy egg-freezing parties, visited high-priced fertility clinics, talked to dozens of women who have frozen their eggs, toured the facility in Italy where the technology was developed, and even attended a memorial service for thousands of accidentally destroyed embryos. What was once science fiction is now simply science: Fertility can be frozen in time. This revolutionary technology offers a new kind of freedom for women-career-focused ones in particular. But does egg freezing give women real agency or just the illusion of it?
