Oocyte Cryopreservation Registry (HOPE Registry)

Subjects will be enrolled at as many ART clinics that offer oocyte cryopreservation and are willing to participate in the Registry. Oocytes will be retrieved and cryopreserved from autologous or heterologous donors. When the subject decides she would like to get pregnant, oocytes will be thawed, fertilized and the resultant embryos will be transferred to the oocyte donor (for autologous use) or to another recipient (for heterologous use). The treatment regimen will be completed with births and well-baby follow-up of children at 12 months of age. Information on children will be submitted by their parents to the Investigators. Data collection for the Registry will be active for a maximum of five (5) years, including three (3) years of enrollment and two (2) additional years to complete the well-baby follow-up for all the children.
