As more women are waiting longer to have children, egg freezing
is becoming more relevant and in demand as many women are facing
the real challenge of having successful, healthy pregnancies
later in life. While we have made great strides in other areas,
our fertility is still limited by basic biology - the
"biological clock" generally stops ticking in our late 30's or
early 40's. Our opportunities are endless, but our egg supply
and egg quality are not, that is why more women are seeking egg
Egg Freezing offers women planning to have children after the
age of 35 the opportunity to effectively slow down their
biological clocks. Extend Fertility's egg freezing services give
women the unprecedented chance to store their eggs during their
reproductive prime for use when they wish to start or expand
Freezing Facts, Breakthroughs & Accomplishments
In the past, difficulty with egg freezing was due to an egg's
tendency to develop ice crystals during the freezing process
(which compromise the integrity of the egg), as well as
hardening of the egg's outer membrane, making fertilization
difficult. Two recent breakthroughs have allowed scientists to
overcome these egg freezing problems.
The first is the development of a new culture media system that
protects from damage during the egg freezing/thawing process.
The media system dehydrates eggs during egg freezing and
rehydrates the egg during thawing, thereby minimizing the
formation of ice crystals during the egg freezing process. The
second breakthrough in egg freezing is a fertilization technique
known as ICSI (Intra-Cytoplasmic Sperm Injection). With ICSI egg
freezing services, the embryologist injects the egg with a
single sperm in order to fertilize it.
While egg freezing is still considered investigational by the
American Society for Reproductive Medicine, by applying these
new advances in cryopreservation, our scientists have realized a
sharp increase in post-thaw survival rates (as high as 90%) and
fertilization rates (as high as 80%). These egg freezing
improvements have led to pregnancy success rates from frozen
eggs of up to 35% per embryo transfer, and have facilitated a
dramatic increase in the number of babies born from frozen eggs
to over 200 worldwide.

The ability to
postpone motherhood through egg freezing was made possible by
the discovery that the age of a woman's eggs is more important
than her biological age. In the last two decades, even
post-menopausal women have become pregnant and delivered babies
by using donor eggs from much younger women. Those developments
created the incentive to preserve a woman's own eggs by egg
freezing while the women are still young. Female fertility peaks
at age 27 and by age 40, the chance of getting pregnant is less
than 10%. Egg freezing and

freezing is expected to have an effect on egg donation by
allowing one donor to store eggs that could be used by several
recipients. Still, perhaps the most compelling current use of
egg freezing is to benefit women with diseases that could
interfere with fertility.
How egg freezing works

a flat dish. Individual eggs are identified with a

- Prepare for
egg freezing Because ice crystals can form within the
eggs and damage them, technicians remove the water from the
eggs and bathe them in an 'antifreeze' solution before egg
freezing. Laboratories vary in how they conduct the egg
freezing process and freeze the female eggs. Some prefer a
slow egg freezing technique, while others use a flash egg
freezing process called vitrification.

Megan (Woman age 36),
Classical Acupuncturist Seattle, Washington WA (USA)
On why she decided to participate in
with Extend Fertility:
"I was starting to feel that my desire to have children was
putting pressure on my current relationship... deciding to
participate in egg freezing helped me to separate the issues -
yes, I want to have children, yes, I am in a relationship, but
my desire to have children shouldn't cloud whether we should be
having children together. I don't want to have children until I
feel emotionally and financially prepared."
On how she feels now:
"Egg Freezing are a very empowering processes. I know there are
no guarantees in this world, but it is a fantastic feeling to
know I've done what I can to preserve my fertility along the
way. Somehow egg freezing was really affirming of what I want in
my life, even though I am not having children right this minute.
I know I want to be a mother more strongly than when I began...
It has removed some of the judgment of myself and self-criticism
of wishing I had done this or that differently, or some blame
I've placed on myself for not having children yet. I feel far
less anxious about the future, no matter what the outcome -
whether I get pregnant naturally at some point, whether I use
these eggs, whether I adopt. Now it's just more about becoming a
mother eventually than judging my body for being not the
"perfect" age biologically."
On working with Extend
Fertility in Egg Freezing:
"I felt very supported by the women at Extend Fertility - like
they were truly my partners in this adventure, their egg
freezing services help me and women like me to have more choices
in the future. The women at Extend are smart, capable, kind
women, there to help me achieve this thing I want. Working with
Extend Fertility was so refreshing compared with trying to
explain to others, even doctors, why I was worried about my
fertility, and not having them get it or just give trite answers
(like, "why make a such a big deal about this?", "you're plenty
young", etc.). I really liked having these women support me in
making the possibility of egg preservation and egg freezing
On advice for
women considering egg freezing with Extend Fertility:
"Listen to yourself. Consider what is most important to you, and
don't worry about what other people have to say about it. Nobody
can know but you what is truly important to you and how you want
to make that happen. When I decided on egg freezing and that I
was going to do it, and was in the process of it, I talked very
openly to people about it as it was happening... At the coffee
shop...how are you today? I'm great! I'm freezing my eggs!
Because I found the experience totally empowering."
Alexandra (Woman age 34),
Pharmaceutical Sales Boston, Massachusetts MA (USA)
On why she decided to freeze her eggs by egg freezing:
"Having a family has always been incredibly important to me and
working in the medical community made me all too aware of the
fact that my aging eggs could potentially jeopardize that dream.
I also didn't want to rush into a marriage that wasn't right
solely to have children. Egg freezing has removed the pressure."
On how she feels now:
"I feel truly amazing...Relieved! I work in the women's health
care arena so I'm constantly bombarded with the scary biological
clock story. I realized last week that I was listening to yet
another horrifying presentation on the perils facing future
mothers over 30 and for the first time I didn't having a panic
attack! I realized that I had taken control and done what I
could to ensure the best chance of having a healthy and happy
baby in the future by egg freezing. It's also really nice that
now thinking about having a family brings a sense of excitement
because it just seems like much more of a reality and not a
deadline that I am terrified of missing."
On working with the Extend
Fertility Egg Freezing Professionals:
"I did a lot of research on egg freezing programs and several of
the female fertility clinics I contacted that advertised egg
freezing and egg harvesting just didn't seem to know much about
it - I often felt like they were reading from a script. They
also made me feel like I would be a peripheral egg freezing
patient because I wasn't doing IVF - egg freezing was just not
what they specialized in. Then I contacted Extend Fertility
about Egg Freezing and everything was totally different. It was
amazing and reassuring to work with women who had actually
participated in egg freezing or frozen their eggs themselves! I
didn't have to justify why I was pursuing egg freezing...they
totally got me. The best part of the egg freezing process was
that they had actually taken the medications and had their own
eggs frozen so they really knew what they were talking about and
what I could expect. I can't say enough about the confidence
they instilled in me and the emotional support they provided me
at every step in the egg freezing process."
On advice for other women
considering egg freezing:
"If you're over 33 and single or involved in a fast track career
you must consider egg freezing now. I promise it will change
your life. The women at Extend Fertility will absolutely help
you with all aspects of egg freezing. You will NEVER regret egg
freezing having frozen eggs...but you could very seriously
regret not having preserved your eggs or participating in an egg
freezing program when you had the chance."
