Egg Donation - The
Recipient
Following a thorough medical
history and examination, and perhaps after alternative courses of treatment,
your physician will discuss egg donation if it is appropriate. You should
consider this option if you and your spouse have ruled out adoption in favor
of the chance to produce a child with your husband’s genetic material, and
you have carefully considered all of the associated issues.
To help you with this important decision, the Institute for Reproductive
Medicine (IRMS) will require that you and your spouse meet with our
psychologist. She will help you consider issues that recipient couples often
face, such as the:
- A sense of loss associated with the
woman’s self-esteem and body image, femininity and inability to make a
genetic contribution.
- Importance of the role of genetic
parenting.
- Source of the donor eggs.
- Risks associated with an IVF cycle, as
well as pregnancy and the demands of parenting at an older age.
- Issues related to disclosure of oocyte
donation the use of a donor egg to friends and family, including the
child.
Finding an Appropriate Egg Donor
Once you have chosen egg
donation, you can designate a potential donor from family, friends or others
sources. However, most couples choose anonymous donors from IRMS’ list of
eligible candidates or an outside egg donor recruitment agency. We recruit
potential egg donors through referrals, advertising and other sources.
Candidates must be between the ages of 21 and 32, and they cannot have donated
more than three previous times. Each egg donor undergoes an extensive
consultation with a donor nurse, along with thorough medical and psychological
screening to determine her suitability for ovum donation. This screening
process, which meets the standards set by the American Society for
Reproductive Medicine, includes:
-
Medical
screening, baseline ultrasounds and blood work to determine
hormone levels, absence of substance abuse, sexually transmitted, or
other diseases, and her physical ability to undergo follicle stimulation
and oocyte retrieval.
-
Genetic
screening, when indicated, to identify individuals carrying
genetically transmitted diseases such as cystic fibrosis, sickle cell
anemia and Tay Sachs disease.
-
Psychological
screening and counseling to discover whether a potential egg
donor understands and is willing to deal with the physical, emotional
and legal ramifications of egg donation. This includes a Personality
Assessment Inventory (PAI).
-
History of egg
donation to make sure that she has not already donated in excess
of our guidelines. If she has not, and a previous donation with us was
successful, she may qualify for a shared egg donor cycle.
Recipient Screening
Both partners are screened to
determine suitability for the egg donation process. This includes an
evaluation and consultation with a physician, donor team nurse and our
psychologist to determine whether they fully understand the nature of the
process, as well as all of the significant implications associated with
creating a child from a donor egg. The physical screening includes a
consultation and examination by a physician, and the following for the female
patient:
- Blood tests
- Antisperm antibodies
- CBC
- CMV
- Hepatitis B and C
- HIV Screens
- Rubella
- Syphilis
- Blood type and Rh factor
- TSH
- Examination
- Catheter check
- Chlamydia and gonorrhea cultures
- Mycoplasma/ureaplasma culture
- Pap Smear
- Special Testing
- Prep cycle
- Cavity check by hysteroscopy, hysterosalpingogram, or sono-hysterogram
- Mammogram (age 35 or family history)
- Additional testing for recipients over age
44
- A system review and evaluation by an internist also may be required for
recipients with medical problems
- EKG
- CXR
- Two hour glucose tolerance test (GTT)
Clinical screening required
for the male partner includes blood tests similar to the females’ and:
- Semen Testing
- Antisperm antibodies
- Semen analysis
- Special Testing (if indicated)
- Canavan’s disease
- Cystic fibrosis
- Gaucher’s syndrome
- Tay Sach’s Disease
- CBC
- Hemoglobin
- Electrophoresis
- Blood Type and RH Factor
Cycle Synchronization for Egg Donation
Once you are matched, you
will be asked to call us on the first day of menses, and to visit our office
on the third day to assess your ovarian function and begin the monitoring
process. Blood will be drawn to determine your hormone levels and you may be
instructed to begin birth control pills. This medication will regulate your
hormone levels, preventing ovulation.
In effect, your reproductive cycle will be on hold to help put you in step
with the donor and prepare for the Suppression Phase of this process.
Suppression
You will be asked to call us
on the first day of menses. Following a visit to our office on Day 21 for
blood work, you will begin an injection of Lupron each night, as instructed by
a donor nurse. Lupron will "turn off" your body’s natural ovarian
stimulation process, and result in a menstrual period in about 7 to 10 days
after the injections begin. You will call us on Day 1 of menses, and visit us
on Day 3 for blood work, ultrasound
and further medication instructions. After that, monitoring will continue in
our office approximately every four days.
If you are on the birth control pill, Lupron may be given (overlapped) at the
same time for 4-7 days. Then the birth control pill will be stopped, usually
inducing menses in 1-3 days. Two to three days after stopping the pill you
will be brought in for an ultrasound and blood work to determine if estrogen
replacement can begin. The Lupron will continue through the estrogen
replacement phase, until progesterone
is started.
Some women without ovaries, or with non-functioning ovaries, will not need to
use Lupron. They will simply stop their usual hormone replacement regimen, get
an ultrasound and blood work, and then start estrogen replacement.
Replacement Phase
On Day 3, while the donor is
taking medications to stimulate her ovaries to produce multiple, mature eggs,
you will begin to take Estrace. This drug, an oral form of estrogen, will be
taken two or three times a day as instructed, to stimulate growth of the
uterine lining. At the same time, you will continue your Lupron injections
each night to preclude development of your follicles and eggs. During this
time, you will visit us approximately every four days for blood work and
ultrasound monitoring.
On the day of egg retrieval, your partner will supply a semen specimen if the
ovum is to be fertilized with his sperm. That night, you will discontinue
Lupron and begin progesterone supplementation in the form of an intramuscular
injection. You will continue the estrogen, although the dose may be adjusted.
You also will take Medrol, a low dose steroid that helps suppress your immune
system and aid in implantation, and an oral antibiotic, Tetracycline, that
will help decrease bacteria in the uterus that might interfere with
implantation.
This protocol of estrogen and progesterone will continue until your pregnancy
test, 11 days after the transfer, and for six or seven weeks beyond that if
test is positive.
Cycle Monitoring
Prior to embryo
transfer, you will be monitored carefully, with periodic blood tests and
ultrasound when necessary, to determine your hormone levels and insure that
you are not producing your own follicles and eggs. Our donor team relies on
these tests to regulate your medications and track development of your uterine
lining to determine that you are ready for embryo transfer. Four days after
the procedures, you will visit our office for blood work, followed by a
pregnancy test nine days later. If you are pregnant, we will continue to
monitor your progress for approximately 4 to 5 weeks (or until you are
approximately 8 to 9 weeks pregnant, at which time your care will be
transferred to your obstetrician.
Embryo Transfer
A few days after the egg
donor’s oocytes are retrieved and fertilized in our laboratory, with sperm
from your spouse or a donor, you will come to our office for the embryo
transfer. Although embryo transfer is a simple technique and anesthesia is not
required, some patients require some medication to relax their muscles. On the
day of transfer, the physician will discuss, with you and your spouse, the
number and quality of embryos being transferred.
During the actual procedure, the physician will pass a long, thin catheter
containing the embryos and a small amount of fluid through your cervix. These
embryos, usually three or fewer, are then injected directly into your uterus.
This procedure is very similar to an intrauterine
insemination and is similar in discomfort to a PAP smear. You will be
asked to start drinking water after you arrive in the Atkins Kent building. A
full bladder during the transfer allows the physician to visualize the uterus
with transabdominal ultrasound and straightens out the cervix, making the
transfer go smoothly.
Following the embryo transfer, you will be instructed to continue required
medications.
Risks and Side Effects
All of the possible risks
associated with being an egg recipient will be discussed with you and your
spouse as part of the informed consent process, prior to the start of your
cycle. The physical effects related to blood testing and hormone therapy are
minimal. Injections, especially intramuscular ones, can be painful. The most
common problems include bruising, discomfort or other minor reactions at the
injection sites. Minor risks associated with hormone therapy include bloating
and breast tenderness, as well as occasional irregular vaginal bleeding.
In rare instances, recipients suffer side effects from estrogen and
progesterone therapy. These can include blood clots and the potential risk of
liver disease, gallstones and high blood pressure, all extremely rare. Also,
the transfer procedure, though simple, carries the risk of cramping,
discomfort, infection or bleeding.
Other Considerations - Egg Donation
Success Rates and Multiple
Births
Our success rates for donor egg cycles are very high compared to other
programs due to a combination of quality oocytes and the expertise of our team
of highly experienced physicians, nurses, embryologists
and other laboratory staff. Our egg donor program is licensed by the State of
New Jersey, NJ and our screening measures go well beyond those employed by
many other programs.
Although the chances for success are significant with oocyte donation, as with
all other IVF cycles, there is no guarantee regarding the outcome. Whether you
become pregnant is affected by factors that differ in every case. You or your
spouse may face clinical problems that preclude fertilization or successful
transfer of the embryos. An egg donor's cycle may be cancelled because of
stimulation problems, she may not produce enough eggs or the eggs may not
fertilize and develop into quality embryos. Finally, when the process is
successful, you may face the risk of multiple pregnancies.
At IRMS, we take steps to avoid multiple gestations by limiting the number of
embryos transferred, but you still may have to choose between having more than
one child and undergoing multifetal reduction to reduce the number of embryos
carried to term.
Psychological Screening and Issue Resolution
Each couple is required to meet with our on-site psychologist before
acceptance into the program, and ongoing emotional
support
is available throughout the process if it is necessary. You will be made aware
of the requirements and implications of the procedure. You also will have the
opportunity to discuss the personal, moral and ethical issues associated with
egg donation, as well as practical considerations, such as the wait for an
appropriate egg donor.
Waiting List
Although we actively recruit egg donors, the number of egg donors is
limited and you may have to wait many months or consider an outside egg donor
agency before our staff finds the right match. The process of donor screening
is very selective and well over 90% of potential egg donors are rejected
during the screening process. The process may be further delayed if the
recipient couple has special requests such as a particular ethnic background
or other specific characteristics in the donor. It is particularly difficult
to find egg donors of Asian, African American and Jewish ancestry. Couples
looking for these types of egg donors are encouraged to place themselves on
the waiting list as well as registering with 1 or more egg donor agencies.
Cryopreservation and Disposition of Embryos
At the end of a cycle, you may end up with more embryos than are required for
transfer, and you will need to consider what to do with them. If those
remaining are of high enough quality, you can consider cryopreservation -
embryo freezing.
Approximately 40% of donor cycles will have extra embryos for freezing. Many
couples wonder what happens in the 60% of cycles that do not have excess
embryos for cryopreservation. In these cycles, excess embryos may be abnormal
or stop growing prior to day 3. Only normal, viable embryos will be frozen.
This will allow you to undergo a subsequent transfer without stimulation, a
process known as a Frozen Embryo Transfer (FET). However, if they cannot be
frozen, they can be donated for research or destroyed.
