Mater semper certa est: motherhood is always certain.

The development of oocyte donation has led to a reexamination of the facets of motherhood: the genetic, gestational, and psychosocial contributions. In addition, the practice of oocyte donation has prompted a consideration of the unique psychosocial and legal aspects of this form of family building. In this section of Views and Reviews a summary and discussion of the long-term psychosocial adjustment of oocyte donor-conceived children and their parents is presented. Next, the current permeability around donor anonymity is investigated and questions regarding whether donor anonymity can still exist is discussed. Third, the evolution of oocyte cryopreservation and banking is reviewed and the future of oocyte banking is explored. Finally, as oocyte donation continues to grow and evolve, so too does the legal landscape in which it is practiced. Seminal legal cases are presented to describe the legal landscape that has shaped the practice of oocyte donation.
