Egg IVF, Houston Texas
egg is a wonderful option for women who cannot use their own eggs
to become pregnant. Women are born with a lifetime supply of eggs
in their ovaries and after puberty eggs are ovulated during each
monthly menstrual cycle. As women age, the quality of their eggs
declines until they reach menopause,
usually in their early forties. Most in
vitro fertilization programs have a maximum age at which women
can attempt IVF using her own eggs because of unacceptable success
rates. Donor egg IVF is
often a first line treatment for women in their forties.
who undergo cancer chemotherapy and/or radiation often experience
damage to the ovaries. Donor egg is an option for these women. Research
is underway to discover techniques to successfully freeze eggs so
that these women can harvest their eggs prior to damaging treatments.
IVF is attempted with these eggs after treatment completion.
eggs will not fertilize and develop for unexplained reasons. Many
specialists believe that this has a genetic basis. One advantage
of IVF is that the embryologist can observe fertilization and embryo
is the hormone responsible for the recruitment and development of
eggs within the ovarian follicles. The FSH level is usually measured
on day three of the menstrual cycle and as egg quality declines,
FSH levels increase. Luteinizing hormone LH levels are also measured
for determination of various hormone ratios. FSH levels above 10
to 12 mcg per milliliter are indicative of reduced ovarian reserve.
is used when a woman has reduced ovarian reserve A donor may be
a friend or relative or she may be anonymous. Anonymous donors usually
receive compensation for the services. All donors undergo thorough
physical and psychological screening.
donors and recipients menstrual cycles are synchronized with hormonal
therapy so that the recipient's uterus will be ready to receive
the developing embryos. The donor receives
ovulation induction drugs (FSH) by injection to stimulate the
development of numerous eggs. Once the eggs mature, they are retrieved
under light anesthesia using transvaginal
guided ultrasound retrieval with a small "needle".
donor's eggs are combined with the partner's sperm and placed in
incubators. Once the embryos are mature they are transferred to
the recipient's uterus. The recipient receives hormone therapy to
properly prepare her uterus.
egg IVF success rates are high mirroring the age group of the donor.
For example, if embryos produced from the eggs of a 22-year-old
female are placed in to a 42-year-olds uterus, IVF success rates
will equal those for 22-year-old females.
McWilliams offers donor egg in conjunction with the Infertility
Center of Houston. There are a wide variety of donors available
of different ethnicity's and physical characteristics.
