Oocyte cryopreservation, more commonly known as egg freezing, has been around for decades but the procedure stopped being considered experimental in 2012. Since then, elective egg freezing has boomed. Often represented as an insurance policy against age- or illness-related fertility decline, the process can be costly and complex.
While figures vary, research suggests most people who undergo egg freezing never access their eggs and results are mixed for those who do. Long-term storage poses its own costs and questions.
