Thawing Cycle Level Live Birth Rate [ Time Frame: Birth of one or more live babies ] [ Designated as safety issue: No ]
Live birth rate per thawing cycle was calculated from the number of live births divided by the number of oocytes thawed less the number of embryos cryopreserved from thawed oocytes, averaged over all thawing cycles.
Prospectively register and track the outcomes of cycles with frozen-thawed oocytes that are fertilized and transferred in subjects [ Time Frame: Multiple timepoints ] [ Designated as safety issue: No ]

  • Oocyte Level Live Birth Rate [ Time Frame: Birth of one or more live babies ] [ Designated as safety issue: No ]
    Oocyte Level Live Birth Rate was calculated from the total number of live births divided by the total number of oocytes thawed less the total number of embryos cryopreserved from thawed oocytes
  • Number of Live Babies [ Time Frame: Birth of one or more live babies ] [ Designated as safety issue: No ]
  • Number of Oocytes Frozen [ Time Frame: At cryopreservation ] [ Designated as safety issue: No ]
  • Number of Oocytes Thawed [ Time Frame: At start of thawing cycle ] [ Designated as safety issue: No ]
  • Oocyte Survival Rate [ Time Frame: At time of fertilization ] [ Designated as safety issue: No ]
    Number of oocytes fertilized divided by number of oocytes thawed per thawing cycle
  • Implantation Rate [ Time Frame: At time of ultrasound after embryo transfer ] [ Designated as safety issue: No ]
    Implantation rate was calculated as the number of fetal sacs per transferred embryo averaged over all thawing cycles
  • Number of Clinical Pregnancies [ Time Frame: At time of ultrasound after embryo transfer ] [ Designated as safety issue: No ]
    Number of clinical pregnancies defined as the presence of one or more fetal sacs with a heartbeat.
  • Number of Miscarriages [ Time Frame: Anytime after embryo transfer ] [ Designated as safety issue: No ]
    Number of pregnancy outcomes reported as spontaneous abortions
Identify factors associated with successful cycle outcomes and to monitor the child's health and development immediately after birth and at twelve (12) months of age, utilizing standard medical practices. [ Time Frame: Multiple timepoints ] [ Designated as safety issue: No ]

Oocyte Cryopreservation Registry (HOPE Registry)
A Phase IV, Prospective, Multicenter, Observational Oocyte Cryopreservation Registry

Phase IV, prospective multicenter, observational Registry will track cycle outcomes for subjects who are thawing frozen oocytes for subsequent use through in vitro fertilization (IVF) and embryo transfer (ET)

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.

Non-Probability Sample

Women of reproductive age who, in order to achieve a pregnancy, will have embryos created from thawed autologously or heterologously implanted oocytes that were either:

  • cryopreserved at the time of or following the Registry's launch, or
  • cryopreserved prior to the Registry's launch, but will undergo thaw/fertilization/transfer procedures while the subject is enrolled in the Registry.
