No guarantees: planned oocyte cryopreservation, not quite an insurance policy.

Planned oocyte cryopreservation (OC) has the potential to address the burden of the biological clock, giving women and individuals with ovaries more autonomy in choosing when to have children and with whom. In the United States, the annual number of OC cycles has grown significantly, yet many questions remain regarding planned OC. The field is starting to gather data on the clinical practice and social perspectives around planned oocyte cryopreservation, including the optimal age range at which to offer planned OC, what factors are most predictive of a successful outcome, and the optimal number of oocytes and ovarian stimulation cycles to achieve a live birth. There is a clear need for setting realistic expectations about the chance of success with OC; however, most patients have yet to return to thaw their oocytes, and outcomes data are limited. Clinical models have been developed to predict OC success based on surrogate markers such as age, number of oocytes retrieved, and anti-Müllerian hormone level. Patient education should emphasize the age-related decline in fertility, that eggs do not equal embryos, and that more than one cycle may be needed to obtain sufficient oocytes to have a reasonable chance of future success. While planned OC is not quite an insurance policy against future reproductive challenges, it provides the best option to date for expanding the reproductive window and maximizing reproductive options while navigating individual life circumstances in the context of family building.
