When to Cancel a Donor Egg IVF Cycle

This is a controversial subject.  In general the same rules that
apply to canceling a regular (non-donor) IVF cycle should apply to
a donor IVF cycle.  You will need to discuss these issues with your
doctor up front before starting the cycle.  Many doctors are
reluctant to cancel unless all indications are terrible.  Because
of the emotional and financial cost of any IVF cycle you may want
to cancel a cycle before retrieval but be aware that you may meet
with resistance from your doctor.   You may still choose to
continue with a cycle that doesn't look promising but be sure it is
an informed decision.  You also need to remember that the donor is
also a patient of your doctor and your doctor is obliged ethically
and legally to provide the best care for her as well as for you.
Here are some guidelines to help you through the process:

1.  You will need to call the office every afternoon to get the
results of your donor's estradiol; you should arrange this before
the cycle starts.  The estradiol should increase steadily over the
course of her pergonal/metrodin; short-term periods (3 or less
days) of modest or no increase may be all right if the donor had
lupron as part of her protocol.  There may be a problem if the
estradiol level stays low or plateaus for more than 3-4 days and
there is definitely a problem if the estradiol level drops.  Most
of the follicles should grow in size at about the same rate.  Near
the time of retrieval the estradiol level should equal
approximately 200 times the number of mature follicles.  Mature
follicles are determined by their diameter; usually a follicle
measuring 16mm or greater is considered mature.

2.  There have been successful transfers and pregnancies with few
retrieved eggs and/or  resulting embryos; your doctor will probably
tell you this.  The belief is that younger women will make great
eggs and resultant embryos even if their number isn't high. 
However there are some things you should know:  First, not all
follicles contain eggs and not all eggs are mature at the time of
retrieval.  It's not enough to know that your donor has 10
follicles, you need to know the number of mature-looking follicles. 
Second, not all eggs will successfully fertilize (even if there is
no male factor) and some will be over-fertilized (with more than
one sperm).  A normal fertilization rate is about 60-70%.  Third,
not all embryos will be of high enough rating (at least a 3 or C)
to give a good chance of pregnancy.  Embryos rated at 4 or 5 do not
usually result in pregnancy.  Fourth, if your program has a good
embryo freezing program it would be nice to have enough to freeze
for another try or a second child.  Most clinics do not freeze
embryos rated below a 3 or C.

It will assist you greatly if you ask ahead of time about the
embryo lab's percentages with regard to these areas:  fertilization
rate, information about quality of embryos, and follicle to egg
relationship.

3.  If you or your doctor cancel a cycle you need to know how much
money you will be refunded from your initial payment.  Most people
will have paid the entire amount up front.  Establish this ahead of
time before the cycle starts.  If you worked with a donor broker
you will need to discuss this ahead of time with him or her as
well.
