Ovary transplant:  

Ovarian cancer is cancer that starts in
the ovaries. The ovaries are the
female reproductive organs that
produce eggs.



CRYOPRESERVATION OF THE
OVARIAN TISSUE
In Denmark a mother had a second
child after ovary transplant. Baby
Lucca and sister Aviaja  are among
just nine children born through the
procedure, where ovarian tissue is
removed, frozen and transplanted.
Their mother was robbed of her fertility
by cancer treatment.
Her doctor said the ovarian tissue was
continuing to function more than four
years after being transplanted back
into her body.
More tissue remains frozen in liquid
nitrogen, and could remain functional
for as long as 40 years.
These results support
cryopreservation of ovarian tissue as a
valid method of fertility preservation
and should encourage the
development of this technique as a
clinical procedure for girls and young
women facing treatment that could
damage their ovaries.

Freezing a piece of a woman's ovary
when she is in her 20s or early 30s so
it can be replanted later in life or after
cancer treatment. This new procedure
could allow women to put off the
menopause indefinitely and conceive
children 'naturally' much later in life.
Doctors said the ovarian tissue could
remain viable in the freezer for 40
years as long if the tissue remains
properly stored in liquid nitrogen.


OVARY TRANSPLANT PROCEDURE
The ovary is removed via keyhole
surgery which reduces recovery time.
The ovary is then frozen until further
notice.

The ovary to be transplanted is thawed
out slowly beforehand. The transplant
procedure is performed as open
surgery this time and involves
reconnecting tiny blood vessels to the
ovary. This enables a steady blood
flow to the ovary which is vital for it to
function.

It will take a few months following
surgery for the ovary to be fully
functional but evidence suggests that
normal hormone production occurs
within 5 months or so.

Another option is to transplant sections
of ovarian tissue rather than the
complete ovary. Some women have
undergone surgery in which strips of
ovarian tissue have been transplanted
onto their defective ovary which then
enables it work again. And this has
resulted in successful pregnancies.

This procedure is still in its infancy but
holds out a great deal of promise for
female infertility in the future.
