Crypreservation and transplantation
of ovarian tissue
Pregnancies and outcome after ovarian tissue cryopreservation and transplantation.
Ovarian cortex cryopreservation was initiated more than 15 years ago and performed
with a view to either future reimplantation or follicular isolation and in vitro maturation
(IVM) (Donnez and Bassil, 1998). IVM of follicles isolated from cryopreserved ovarian cortex
has not yet resulted in pregnancy, but the reimplantation technique has yielded pregnan
cies and live births (30 in about 15 years, Donnez, december 2013)
Most of patients undergoing ovarian cortex reimplantation have demonstrated restoration of ovarian function, experiencing follicular development and ovulation.
Cryopreservation of ovarian tissue is the only fertility preservation option available for
pre-pubertal girls and for women who cannot delay the start of chemotherapy
Maltaris et al., 2009
Crypreservation and transplantation
of ovarian tissue
At present 30 healty babies have been born from frozen-thawed ovarian
tissue grafting orthotopically. How much is the denumerator, 30/ ?
Grynberg et al., 2012
Orthotopic transplantation allow to the resumption of menstrual cycle
and to natural conception, with endocrinological function up to 2-5 y.

Crypreservation and transplantation
of ovarian tissue
Conclusion: VT offers similar
conditions to fresh tissue for
follicular density proliferation,
viability, cell death and preserves a larger population of
quiescent follicles than S.F.
after transplantation, thus ensuring the maintenance of
graft potential fertility
Crypreservation and transplantation
of ovarian tissue
Conclusions: An approach using ovarian stimulation first, followed by laparoscopic collection of
ovarian tissue, is a useful
strategy
for
increasing
the efficacy of fertility preservation techniques. The
ovarian tissue is not affected by prior ovarian stimulation

Crypreservation and transplantation
of ovarian tissue
A strategic combination of approaches may maximize
efficiency while avoiding any compromise to cancer
treatment: ovarian tissue cryobanking with immature
oocyte aspiration and IVM or ovarian stimulation and
mature oocyte retrieval and ovarian tissue cyobanking

Aspettative Attuali - IVM
The development of follicles is regulated by a complex mixture of
inhibitory and stimulatory endocrine, paracrine and autocrine signalling
by the somatic cells (granulosa and surrounding theca cells) enhanced
by a range of oocyte specific regulatory factors mediated through bidirectional communication within the follicle

Aspettative Futuribili
Ovaio artificiale - Stem Cells
Aspettative Attuali – Ovaio artificiale
For women diagnosed with leukemia, transplantation of cryopreserved ovarian tissue after disease remission is not advisable.
Therefore, to restore fertility in these patients, we aim to develop a biodegradable artificial ovary that offers an environment
where isolated follicles and ovarian cells (OCs) can survive and
grow. After transplantation, this matrix was able to degrade,
allowed vascularization and elicited a low inflammatory response.

Aspettative Futuribili - Stem Cells
Le ovaie contengono un pool di follicoli
predeterminato durante la vita fetale e
mai piu’ rinnovabile
Dimostrata l’esistenza di OSC oogonial stem cells aventi la capacità di
mantenere la produzione di ovociti e
follicoli anche dopo la nascita con
concentrazione decrescente in base
alla età

The future:
making oocytes from germ line stem cells?
Development of culture systems that support human oocyte
development MAY WELL OFFER practical solutions to fertility

for
many
women
for
whom
conventional
methods cannot be used but there is still a LONG WAY TO GO
before all the relevant testing can be carried out
