WHAT IS OOCYTE DONATION?
Oocyte Donation is the procedure whereby a woman has a routine IVF cycle
and the oocytes (eggs) from this woman (donor) are given to a recipient
couple. The sperm from the recipient male is used to fertilize the oocytes,
and all subsequent embryos that form are frozen and stored (cryopreserved).
In a future cycle embryo/s are thawed and inserted into the recipient woman’s
uterus with the intention of her becoming pregnant. The treatment has been
used for many years and has a high success rate.
WHO CONSIDERS OOCYTE DONATION
Approximately one in 35 women of reproductive age are unable to produce their
own eggs. Indications for this include those women:
i). entering menopause (prematurely);
ii). having no ovaries;
iii). having hereditary disorders;
iv). having inaccessible ovaries (unable to collect her oocytes);
Once it has been diagnosed that the female partner is unlikely to be able
to produce her own oocytes, the couple has three choices. One is not to have
children. Secondly, the couple can aim to adopt a child. Unfortunately this
may be difficult as there are few children for adoption and waiting lists
are very long. The third choice is using donated oocytes.
Oocyte Donation has the advantage that a pregnancy can be shared by the couple
and half the genetic make-up comes from the male partner. The shared experience
starts with the excitement of the missed period, the diagnosis of pregnancy
and continues throughout the pregnancy, climaxing with the delivery of the
child.
Unfortunately, Oocyte Donation cannot protect the expectant mother from the
complications of pregnancy and childbirth. Women who have children by Oocyte
Donation have exactly the same risk of an abnormality in their children as
those who conceive naturally. There is no decrease or increase in the risk
of congenital abnormality.
ASSESSMENT OF OOCYTE DONORS
The selection of women who apply to become oocyte donors is complex. In order
to be considered as a possible donor, a woman must be aged between 18 and
35 years.
The donor will be seen by her specialist doctor who will discuss medical
issues and the Oocyte Donation IVF procedure. Prospective donors must provide
a full personal and family medical history and answer questions specifically
about activities associated with risk of (HIV) AIDS infection. The specialist
doctor will examine the donor, review the family medical history, and ensure
that the donor is in good health. Blood tests for hormone levels, Hepatitis
B, C, and HIV antibodies, Syphillis and Blood Group and any other indicated
investigations will be required.
When the donor has been initially approved by the specialist doctor, they
are then required to attend a counselling session to ensure complete understanding
about what is involved and the legal and moral issues associated with becoming
an oocyte donor. The counselling session reports are sent to the specialist
doctor for review and are part of the approval process.
A four month “cooling off” period from the initial consultation
with the specialist is required before oocyte collection or donation can
take place.
WHO ARE THE DONORS?
Many people are interested to know what kind of women become donors. Studies
indicate the most common characteristic donors possess is a desire to help
others. Oocyte donors are often blood donors and many report having friends
or family who have had a fertility problem.
The donors of oocytes are few in number; approximately one or two anonymous
oocyte donors come through the clinic per year. It is suggested, therefore,
that a couple who are seeking donated oocytes ask their family and/or friends
if they would be an egg donor for them.
OOCYTE COLLECTION
The donor undergoes a stimulation program using hormone medications (including
a period of daily injections) to produce a number of Oocytes. These are collected
in a Day Surgery operation called “Oocyte collection” (refer
IVF literature). All out-of-pocket costs are to be met by the recipient couple.
Please see the explanation of fees sheet for this information.
All oocytes collected are fertilised using the recipient male partners sperm
and all resulting embryos are frozen and stored for use by the recipient
couple.
THE SIX MONTH QUARANTINE PERIOD FOR EMBRYO STORAGE
It is recommended by RTAC (Reproductive Technology Accreditation Council)
that donated gametes (sperm and eggs) be frozen and stored for a period of
six months (quarantined). The donor is then to be retested for Hepatitis
B, C and HIV, and embryos released if all test results are negative. The
policy of the Canberra Fertility Centre is to follow this RTAC recommendation.
AFTER THE EMBRYOS ARE FROZEN
Transfer of embryos to the recipient woman can occur after the recommended
six month quarantine period.
Ovulation is monitored by blood tests and ultrasounds to predict the exact
timing of ovulation. Medications may be used to enhance the cycle. The embryo
transfer is a simple procedure rather like having a Pap Smear Test. It is
done in the clinic and does not take long. There is further information available
in the IVF information booklet on Frozen Embryo Transfer.
If a pregnancy does not occur the treatment may be repeated during subsequent
menstrual cycles if further embryos are available.
DONOR SELECTION FOR COUPLES
Couples are given the non-identifying information about the donor. This information
includes race, ethnic origin, height, build, hair and eye colour and blood
group.
Couples are provided with oocytes from a donor whose physical characteristics
most closely resemble those of the female partner, although other factors
such as ethnic origin and blood group may influence the decision. The availability
of oocytes often makes close matching very difficult.
Consent and documentation must be read and clearly understood before accepting
this type of treatment.
DECISION MAKING
In our society today there are many different ways to form a family. Oocyte
Donation is one way many couples have chosen to produce their families. However,
the decision may not always be straightforward, nor may each partner be certain
that this method of family formation is for them.
The decision to start on an Oocyte Donation program is one made by the couple
in consultation with their doctor. It is, however, a decision which we consider
to be a serious one and it may not be the right choice for all couples. Even
for those couples who proceed to Oocyte Donation, there can be social and
emotional hurdles to be overcome. All couples approaching the Oocyte Donation
service should discuss their concerns with the centre counsellor.
The counsellor is required by the John James Hospital Ethics Committee to
write a report and the cost for this is incurred by the recipient couple.
The cost is $250 for the donor and another $250 for the interview of the
recipient couple.
The clinic counselling service offers the opportunity to discuss the issues
that might arise if a couple proceeds with oocyte donation. The counsellor
may also be in a position to discuss the issues which have arisen for other
couples who have children from the program. The legal aspects and issues
such as telling the family, friends and the children about oocyte donation
will be discussed with you in the counselling session.
KNOWN DONORS
Some couples decide that the use of a donor known to them is preferable to
the notion of an unknown donor. This is perfectly acceptable under ACT law
and the same legal position applies to both known and unknown donors. A known
donor, her partner and the recipient couple, will discuss their plans with
their doctor and then the centre counsellor before donating or receiving
oocytes.
KNOWN DONOR QUARANTINE PERIOD WAIVER (“well” known donors)
A known donor must have been associated with the recipients for some time
(such as a sister or cousin) for waiving of quarantine purposes. With a “well” known
egg donor, the recipient couple may elect to waive the six month quarantine
period and transfer the embryos after a shorter period or attempt a fresh
transfer. A request for quarantine waiving in these circumstances needs to
be fully discussed with the specialist doctor. A quarantine waiver document
needs to be signed by the recipients acknowledging the unknown risk and the
donor will still be required to have a repeat blood screen six months post
donation for the file record.
OOCYTE DONATION - IMPLICATIONS AND CONSIDERATIONS FOR THE CHILD, PARENTS
AND DONOR
• Does a child have the right to know about his or her origins?
• Are there dangers inherent in attempting to keep Oocyte Donation
a secret from the child? Or the family?
• The decision to tell or not to tell friends and family?
• Practical difficulties - travelling to and from the doctor or Canberra
Fertility Centre, explaining to employers the need to arrive late, leave
early, or even take days off, and possibly feeling uncomfortable giving a
reason why.
