Egg Donation Process

Being selected as a donor by one of our recipients leads to a very exciting and rewarding journey to help make a dream of becoming parents come true. We hope that you have carefully evaluated your decision to become an egg donor. It is a serious commitment when you choose to participate in an egg donor cycle, and the results are gratifying. We appreciate your generosity and compassion for these infertile couples.
The length of your commitment once you are selected for an egg donor cycle can be as few as six weeks and as long as four months. Egg Donation, Inc. is not a medical facility, but we have relationships and work with the best Reproductive Endocrinologists across the nation who will work to ensure your safety and well being and can explain the full medical procedure of egg donation. A goal of our staff is to make your journey as enjoyable and fulfilling as possible. We know the time and effort it takes to be an egg donor and we treat all our donors with the care and the respect they deserve.

How Egg Donation Works

Step 0: Egg Donor Application and Screening

Before everything else can happen, egg donors must apply to our egg donation program, go through an initial screening and two rounds of interviews (one with our clinical coordinators and another with our physicians) as well as some testing. Only the donor applicants who pass all these screening steps will be added to our egg donor program, and can be matched with a recipient couple. CHR's egg donor program is very selective: on average, we accept only about 1-3% of applicants to our donor program.

Step 1: Egg Donor Matching

When a couple decides to use donor eggs, they can view the pre-screened pool of egg donors online, and select a candidate from the pool. A tentative donor egg match is made when a recipient decides to move forward with a specific donor. Our IVF coordinator will contact the egg donor to confirm her availability. If the egg donor is available for the recipient's desired time frame, and passes an FDA-required round of testing, an official match is made. Some donors are selected and matched to a recipient very quickly after they apply; others may take months or years before they are selected; still others may never be selected.

Step 2: Suppression and Ovarian Stimulation for the Egg Donor

The egg donor will self-administer daily injections of a medication called Lupron to suppress her natural cycle, so that her and the recipient's cycles are synchronized. During the ovarian stimulation phase, the egg donor uses daily injections of gonadotropin to stimulate her ovaries. In a natural cycle, only one egg matures; gonadotropins injections encourage more than one egg to mature for retrieval.
During ovarian stimulation, the egg donors are monitored closely through blood tests and ultrasound, ensuring that the ovaries are responding well and not going into hyperstimulation. This means that egg donors need to visit our center in the Upper East Side of Manhattan frequently during this phase. (Long-distance donors go to collaborating IVF centers that are local to them.) These monitoring sessions are scheduled in early morning in order to avoid interfering with the donors' daily schedule of school and work.

Step 3: Endometrial Lining Development for the Donor Recipient

On the recipient's side, a favorable uterine environment, especially an endometrium of at least 7 mm, is crucial in the success of a donor egg cycle. While the egg donor develops eggs for retrieval, the recipient takes estrogen and progesterone to prepare her endometrial lining for implantation. Developing the endometrium for embryo transfer is usually not a problem.
In rare cases, some patients have difficulties in reaching minimal endometrial thickness and may require special treatments. Fortunately, CHR has demonstrated special expertise in this area. Some patients with autoimmune abnormalities may use additional medications to improve the chance of implantation.

Step 4: Triggering Ovulation and Egg Retrieval for the Egg Donor

When the ultrasound imaging shows that the donor's eggs have sufficiently developed, the donor will be instructed to trigger ovulation with an injection of hCG. Two days later, her eggs are retrieved in a short in-office procedure, called egg retrieval. While the donor is asleep (under I.V. sedation), one of our physicians will use aspiration needle, guided by ultrasound, to transvaginally retrieve the eggs. The donor will be required to take the rest of the day off to recover.

Step 5: Fertilization and Embryo Transfer for the Recipient

The retrieved eggs are fertilized with partner's or a donor's sperm. If using fresh sperm, the partner will need to visit CHR to produce a sample at this time. The embryos that result from this fertilization are incubated and graded. Normally, embryos are transferred into the recipient's uterus on day 3 after donor egg retrieval (on rare occasions on day 5). For our recipients working with our center's egg donor program from outside the NYC metro area, this is the only time they need to be in NYC for the entire cycle. The rest can be managed locally.

Step 6: Post-Retrieval Checkup for the Donor and Pregnancy Tests for the Recipient

The donor will be required to return to our center for a post-retrieval checkup, so that we can make sure that the donor is recovering properly from both the ovarian stimulation and retrieval. In most cases, donors have no problem returning to normal in a day or two after egg retrieval, and if this is not the case, our clinical team closely monitor the donor's progress and stay in touch with her until the donor fully recovers. From the start of the Lupron injections to egg retrieval, egg donation is a 3-5 week process for most of the egg donors.
Recipients will have a pregnancy test two weeks after the embryo transfer, via a blood test that measures the level of hCG. After two normally rising hCG tests and an ultrasound demonstrating a pregnancy, recipients are "discharged" to their obstetricians for prenatal care.

 Frozen Donor Egg Program (EcoDEP)

CHR also offers a frozen donor egg program called Eco Donor Egg Program (EcoDEP), in which a recipient receives eggs from a donor who has already undergone ovarian stimulation and egg retrieval by the time the recipient chooses her donor. This means that EcoDEP has a different "workflow" from the standard egg donor program described here.
