Oocyte cryopreservation review: outcomes of medical oocyte cryopreservation and planned oocyte cryopreservation [PDF]
Reproductive Biology and Endocrinology, 2022 Abstract Background The utilization of oocyte cryopreservation (OC) has become popularized with increasing numbers of reproductive-aged patients desiring to maintain fertility for future family building. OC was initially used for fertility preservation in postmenarchal patients prior to gonadotoxic therapies; however, it

Implications of oocyte cryostorage for the practice of oocyte donation [PDF]
Human Reproduction, 2012 As the efficiency of oocyte cryopreservation has increased rapidly in recent years, oocytes are currently being stored either in the course of IVF treatments or as a fertility preservation measure. These practices may have an impact on the number of available donor oocytes due to two different dynamics: first, a certain percentage of women for whom ...

Human Reproduction, 1998 Cryopreservation of human oocytes has been employed with little success in clinical practice, even though it may solve the legal and ethical problems linked to embryo freezing. Various attempts to cryopreserve human oocytes have mostly been unsuccessful, leading to low oocyte survival rates after thawing, and the search for an optimal protocol for ...
