Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
We plan to enroll 12 recipients and 6 donors in this study. Each egg donor will go through a stringent screening process (medical, genetic and psychological). Eggs retrieved from all donors will be split in half: one half will be frozen by the slow freeze method, and the other half by vitrification. Each of the six donors will be paired with two recipients; each recipient will be assigned half the total eggs frozen. For each recipient, half of the eggs will come from the slow freeze group and the other half will come from vitrification.
When the recipient's uterine lining is deemed ready (following estrogen treatment and ultrasound monitoring), thawing will be performed on eggs frozen by either the slow freeze or the vitrification method. The thaw process will be randomized between the two types of freezing. One sperm will be injected into each egg that survived the freeze. Fertilization and embryo development will be recorded. Ideally, two embryos will be transferred into the recipient's uterus. Pregnancy will be determined by a blood test and followed by serial blood tests and ultrasound.
The study will determine which freezing method yields better survival and pregnancy rates.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
slow freeze
these recipients will have their first embryo transfer with oocytes frozen via the slow freeze method.
oocyte freezing
retrieved oocytes from the donor will be split in half and frozen by both existing egg freezing methods: slow freezing and vitrification. The recipients will then be randomized as to which group of eggs will be thawed out for their first attempt at achieving a pregnancy.
vitrification
these recipients will have their first attempt at an embryo transfer with oocytes frozen via the vitrification method.
oocyte freezing
retrieved oocytes from the donor will be split in half and frozen by both existing egg freezing methods: slow freezing and vitrification. The recipients will then be randomized as to which group of eggs will be thawed out for their first attempt at achieving a pregnancy.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* recipients: women under the age of 50 who wish to have eggs donated to them through the Donor Egg Program and who aslo pass the medical, physical and psychological screening.
Exclusion Criteria
* recipients: those who do not pass the screening.
The genetic screening of donors will involve the following:
* All donors will be screened for Cystic Fibrosis, Fragile X and Spinomuscular Atrophy (SMA).
* In addition, donors of Ashkenazi Jewish origin will be screened for Gaucher's disease, Canavan,Tay -Sachs, Familial Dysautonomia, Niemann Pick, Fanconi's Anemia, Bloom and Mucolipidosis Type IV.
* Donors of African-American origin will be screened for Sickle-Cell disease.
* Donors of Asian, Mediterranean, Latino or Hispanic origins will be screened for Thalassemia.
Recipient Screening: A Reproductive Endocrinologist (RE) at the Center will take a detailed history and perform a physical examination on all potential recipients. The RE will assess the health of the potential recipient in order to assess her capacity to carry a pregnancy. Previous IVF cycles, successful or unsuccessful, will have no implication on recipient selection.
The recipient and her partner (if applicable) will meet with the program psychologist. The psychological evaluation is detailed below.
Psychological evaluation: A psychological evaluation will be conducted of the Recipient, her partner (if applicable) and the Donor. The purpose of these evaluations is to determine the suitability of the parties to participate in the Donor Egg Program. Psychological tests will be administered by the Center as part of the evaluation process.
These evaluations may result in a recommendation that one and/or all of the parties not participate in the Donor Egg Program. The psychologist will not be providing any advice or treatment to the Donor or Recipient(s). Nor will the Donor or Recipient(s) be entitled to the results of the Psychologist's evaluation. The Psychologist will provide the results of his/her evaluations to the Center for Human Reproduction.
As with our standard Donor Egg Program practices, there will be an upper age limit of 50 years for all recipients participating in the study.
