Egg freezing program
Bangkok IVF Center currently offers egg
freezing program (Oocyte Cryopreservation) to
women who are planning to use their own eggs in
the future due to aging problem or malignancy
prior to chemotherapy.
As the chances of getting pregnant decline as
you grow older, egg freezing program gives women
an opportunity to preserve their fertility
potential by preserving fertile eggs in frozen
This procedure is ideal for women who facing
chemotherapy for cancer treatment since eggs in
their ovaries will become damaged after
chemotherapy. So preserving their fertile eggs
prior to chemotherapy will be the only way to
preserve their fertility.
Fertility of women become lower as they grow
older, after 35 years of age, their fecundity
begins to be lower and after 40 years of age, it
will be difficult to get pregnant. Freezing eggs
at younger age is the way to prevent age barrier
and maintain the good chance of pregnancy.
Not only you can store eggs for future usage,
but also you can freeze extra eggs from assisted
reproduction technology programs such as IVF or
ICSI instead of freezing embryos which will be
another way to prevent moral or ethical concerns
about destruction of unused frozen embryos since
eggs are not considered as life form.
Usage of frozen eggs:
There can be wide variation in the percentage of
eggs that survive freeze and thaw process. It is
possible that no eggs will survive the freeze
and thaw process at all. Eggs are kept in liquid
nitrogen tank until thawing is performed. Eggs
can theoretically be stored for years and viable
after thawing. Thawed eggs require sperm
injection or ICSI for fertilization. Even with
viable eggs after thawing, embryos developed
after fertilization may not guarantee pregnancy.
In order to obtain eggs for freezing, you have
to go through control ovarian hyperstimulation
program similar to those who undergo IVF
program. Eggs are then retrieved via
sonographically guided transvaginal needle
aspiration under intravenous sedation.
The work up for egg freezing program is similar
to those with IVF program. The difference is
that the eggs are frozen while still
unfertilized. Once the eggs are planned to used,
they had to be thawed and ICSI is required to
initiate fertilization before embryos are
growing enough to be transferred.
