Ovum Donation
More than 150,000 women in the United States can't bear children
because of ovarian problems. Many women do not produce eggs, or have had
their ovaries removed, have had radiation therapy or chemotherapy for
cancer that destroyed their ovarian function, or have dysfunctional
ovaries, and are no longer producing high quality eggs. Other women have
deferred pregnancy until their late thirties or forties. Since the
ovaries age at such dramatically different rates in different women,
while some conceive quickly, others are no longer able to conceive using
their own eggs and require donated eggs to conceive.
Egg donation is a
treatment that uses the male partner's sperm to fertilize
eggs donated
by an anonymous female donor, and is followed by transfer of the
fertilized egg into the female partner's uterus.
Egg donors are typically healthy women between ages 21 and 31 who
have no known genetic or sexually transmitted diseases. They should be
screened for genetic, hormonal, psychological, infectious, and physical
diseases. Egg donors usually take injectable hormones for eight to ten
days to increase their egg production. Donor eggs are retrieved transvaginally using an ultrasound to guide the procedure. The recipient
of the donated eggs usually takes hormones to synchronize her cycle with
the donor's cycle and to prepare her uterus to receive the embryos and
thus enhance the likelihood of implantation occurring. These hormones
include estrogen which can be taken orally or administered in patches
that attach to the skin and progesterone administered by injections. As
in IVF, three embryos are normally transferred to increase the couple's
chances of pregnancy. In a good program, more than 50% of ovum
recipients should receive positive pregnancy tests on their first
attempt.
