Donor Egg Program - For Intended Parents
Women with egg quality issues may still have options for enjoying
a pregnancy, with the help of other women who are willing to donate
eggs.
If you do not have functioning ovaries or usable eggs, but you do
have a uterus that responds to hormonal signals and can support a
pregnancy, you may be able to use donated eggs. This means that a
fertile woman would supply eggs that can be fertilized in the
laboratory with your partner's sperm, using the techniques of in
vitro fertilization (IVF). The resulting embryos would then be
implanted into your uterus, for you to carry the pregnancy.
Most fertility clinics in the United States offer the option of
using donor eggs to women up to the age of natural menopause, about
age 50. Egg donation may be suggested in cases such as these:
- You no longer have ovaries, but do have a hormonally
responsive uterus.
- Your eggs have been determined to be unsuitable or
abnormal, as typically occurs with age, ovarian resistance,
ovarian failure, and poor ovarian reserve.
- You have poor embryo quality that has brought about repeated
failures with IVF.
- You carry a genetic disorder.
Most egg donors are between 21 and 33 years of age and are
screened according to the FDA guidelines.
The donor may be anonymous or someone you know. Most recipients
use an anonymous egg donor and rely on their fertility clinic to aid in the search for a donor.
Anonymous donors
are paid for their services. Regardless of whether the donor
is known or anonymous, she is thoroughly screened for her personal,
medical, surgical, psychiatric, and genetic (family) history.
The egg donation procedure involves the following steps after
appropriate counseling:
- Donor selection and examinations. Donors are examined
and screened for medical and genetic disorders. A donor will be
selected by you based on desired qualities, such as hair color,
eye color, and height. You will be examined, too, to rule out
health problems and to ensure you have a normal uterus.
- Synchronization of your menstrual cycle with the donor's.
This step occurs if you have ovaries and a cycle of your own.
Both you and the donor will receive oral contraceptives; this
allows you to start the medications at any time. About two weeks
later, both you and the donor will be evaluated with ultrasound
and a blood test to ensure your ovaries are suppressed.
- The donor cycle. Your donor will undergo ovulation
induction to stimulate her ovaries so that eggs can be retrieved.
Meanwhile, you will need to take estrogen hormone replacement to
prepare your uterus to receive an embryo. You may be given
estrogen as a pill, skin patch, or injection, either in a fixed
daily dose or a steadily increasing dose over 12 to 21 days. We
will use ultrasound to see whether your uterine lining has reached
the necessary thickness of 6 mm to 14 mm.
- Egg retrieval. Once the donor is scheduled for egg
retrieval, you will be started on progesterone replacement as well
as estrogen replacement.
- Insemination and fertilization. On the day of egg
retrieval, your partner will be asked to provide a semen sample,
or a sample from a licensed sperm bank will be thawed and
processed for egg insemination. This is done as with any IVF
procedure.
- Egg transfer. Once the eggs are fertilized, the
resulting embryos will be assessed and chosen for transfer as with
any IVF procedure. Timing of the transfer depends on the office
procedures, but it is generally between two and six days after
fertilization (most commonly 5 days).
- Hormonal supplementation during early pregnancy. You
should have a positive pregnancy test about 14 to 18 days after
transfer. You will continue the estrogen and progesterone
supplementation until about 10 weeks of pregnancy.
