Successful pregnancy [ Time Frame: until the patient reaches 50 years of age ] [ Designated as safety issue: No ]
Eggs will be frozen via vitrification for those females electing to preserve their fertility; patients will return following an unspecified time period, when they are ready to use their frozen eggs. At that time, the eggs will be thawed and fertilized (with the sperm source of the participant's choice) to create embryos. This time frame will be unique to each individual; however, the Center has a policy whereby no embryo transfer will be performed beyond the age of fifty (50).

  • oocyte survival [ Time Frame: up to 50 years of age ] [ Designated as safety issue: No ]
    the number of eggs that successfully survive the frozen-thawing procedure (vitrification).
  • fertilization [ Time Frame: up to 50 years of age ] [ Designated as safety issue: No ]
    to calculate the rate for the number of oocytes that are successfully fertilized (via ICSI) following survival of the frozen-thaw procedure.
  • blastocyst formation [ Time Frame: up to 50 years of age ] [ Designated as safety issue: No ]
    calculates the number of successfully fertilized embryos that grow into blastocysts (day 5 of culture), created from eggs that underwent and survived vitrification.
  • implantation [ Time Frame: up to 50 years of age ] [ Designated as safety issue: No ]
    to determine the implantation rate of embryos that were created from vitrified oocytes.

Oocyte Cryopreservation
Oocyte Cryopreservation

The purpose of this investigation is to offer the opportunity for young women to cryopreserve (freeze) their oocytes (eggs) for use with IVF at a later point in time.
