Abstract
Cryopreservation of ovarian tissue is an important option for preserving the fertility of cancer patients undergoing chemotherapy and radiotherapy. In this study, we examined the viability and function of oocytes derived in vitro from pre-antral follicles as an alternative method for restoring fertility. Pre-antral follicles (specified as secondary follicle with a diameter around 100-130 μm) were mechanically isolated from vitrified-warmed and fresh adult mouse ovarian tissues and cultured for 12 days followed by an ovulation induction protocol at the end of this period to initiate oocyte maturation. Oocytes were then released from these follicles, fertilized in vitro, and cultured to the blastocyst stage and vitrified. After storage in liquid nitrogen for 2 weeks, groups of vitrified blastocysts were warmed and transferred into pseudo-pregnant recipient females. Although most of the isolated mouse pre-antral follicles from fresh (79.4%) and vitrified (75.0%) ovarian tissues survived the 12-day in vitro culture period, significantly fewer mature oocytes developed from vitrified-warmed pre-antral follicles than from the fresh controls (62.2 vs 86.4%, P<0.05). No difference was observed in embryo cleavage rates between these two groups, but the proportion of embryos that developed into blastocysts in the vitrification group was only half that of the controls (24.2 vs 47.2%, P<0.05). Nevertheless, live births of healthy normal pups were achieved after transfer of vitrified blastocysts derived from both experimental groups. This study shows that successful production of healthy offspring using an in vitro follicle culture system is feasible, and suggests that this procedure could be used in cancer patients who wish to preserve their fertility using ovarian tissue cryopreservation.

Abstract
Abstract In recent years, removal of ova or ovaries before chemotherapy or radiation therapy has been investigated in young female cancer patients to avoid the adverse effects of treatment. Orthotopic autotransplantation of ovarian cortex has advantages such as easy collection of ova and the possibility of spontaneous pregnancy. Although children have been born after successful orthotopic autotransplantation into the residual ovaries, some patients cannot undergo this procedure such as those who need bilateral ovariectomy or pelvic radiation therapy, therefore it is still necessary to investigate suitable heterotopic autotransplantation sites. The present study was performed in primates (cynomolgus monkeys) with the objective of determining the optimum site for heterotopic autotransplantation of ovarian cortex to enhance the clinical application of this method. The retroperitoneal iliac fossa and omentum were selected as sites for heterotopic autotransplantation. Two cynomolgus monkeys were subjected to laparotomy under anesthesia. After resection of the bilateral adnexae, the ovaries were cut into 0.5 cm cubes that were transplanted. Blood levels of follicle-stimulating hormone, luteinizing hormone, estradiol, and progesterone were monitored, and monkeys with a regular estrus cycle underwent superovulation and egg collection. In both monkeys studied, recovery of a regular estrus cycle was confirmed after heterotopic autotransplantation of ovarian tissue. MII phase ova were successfully collected from tissues transplanted into the retroperitoneal iliac fossa or omentum. Development to the early blastocyst stage was confirmed after microfertilization. We established an appropriate method of heterotopic autotransplantation using ovarian cortex into the retroperitoneal iliac fossa or omentum in primates.

Abstract
Abstract
Ovarian tissue cryopreservation is currently proposed to young cancer patients to preserve their fertility before radiochemotherapy. The potential risk is that the tissue might harbor malignant cells that could induce disease recurrence. We therefore decided to evaluate the presence of leukemic cells in cryopreserved ovarian tissue from 18 leukemic patients: 6 with chronic myeloid leukemia (CML) and 12 with acute lymphoblastic leukemia (ALL). In each case, histology, quantitative reverse-transcribed polymerase chain reaction (RT-PCR) and long-term (6 months) xenografting to immunodeficient mice were used. Histology did not identify any malignant cells in the ovarian tissue. By quantitative RT-PCR, 2 of 6 CML patients were positive for BCR-ABL in their ovarian tissue. Among the 12 ALL patients, 7 of the 10 with available molecular markers showed positive leukemic markers in their ovarian tissue (translocations or rearrangement genes). Four mice grafted with ovarian tissue from ALL patients developed intraperitoneal leukemic masses. In conclusion, this study demonstrates, by quantitative RT-PCR, ovarian contamination by malignant cells in acute as well as chronic leukemia, whereas histology fails to do so. Moreover, chemotherapy before ovarian cryopreservation does not exclude malignant contamination. Finally, reimplantation of cryopreserved ovarian tissue from ALL and CML patients puts them at risk of disease recurrence.

Abstract
OBJECTIVE To describe a cohort of 12 Danish women who received autotransplantation of frozen-thawed cryopreserved ovarian tissue because of premature ovarian failure after cancer treatment. DESIGN Retrospective study. SETTING University hospitals. PATIENT(S) Twelve women with autotransplanted frozen-thawed ovarian tissue. INTERVENTION(S) Monitoring of hormonal parameters and results of 56 IVF cycles in 10 women. MAIN OUTCOME MEASURE(S) Levels of gonadotropins and sex steroids, functional life span of the grafts, and results of IVF. RESULT(S) All 12 women regained ovarian function between 8 and 26 weeks (mean 19 weeks) after transplantation. Ten women underwent a total of 56 IVF cycles, 76 follicles developed, 49 oocytes were aspirated, 18 were fertilized, and 16 embryos were transferred resulting in six pregnancies: two biochemical, one clinical that miscarried in week 7, and two ongoing resulting in the delivery of two healthy infants born at term to two women. One of these women subsequently conceived spontaneously and delivered another healthy infant. The life span of the transplanted tissue has been between 6 months and still functioning after 54 months. CONCLUSION(S) Autotransplantation consistently leads to recovery of ovarian function after treatment-induced ovarian failure. Four women became pregnant, after IVF or spontaneously, resulting in the delivery of three healthy infants.

Abstract
PURPOSE The objectives of this study were (1) to determine what young cancer survivors know about the effect of their cancer on fertility, how fertility difficulties affected their lives and whether they would opt for fertility preservation (FP) and (2) to assess the sources of information and the helpfulness of them. METHODS Women of at least 18 years with cancer affecting reproductive function were recruited from eight cancer websites for this online survey. The Cancer and Fertility Survey (CFS) contained items from validated inventories and items to assess fertility issues in cancer patients. Quantitative analyses (t-tests, chi(2), analysis of variance) and thematic analysis of free text data were performed. RESULTS Of the 80 participating women, 68.1% rated the risk of infertility as high. The mean number of professionals consulted was 3.56 (SD = 2.7), but 20% of women had not discussed fertility with any professional. The weighted mean helpfulness index was the highest for spouses and oncologists. Strength of positive attitudes towards FP was significantly greater than that of negative attitudes. CONCLUSION The need to discuss fertility is high among women searching for information on cancer websites. Options to preserve fertility were positively viewed but the actual use may be limited by concerns about safety.

Abstract
OBJECTIVE To compare early follicular growth after fresh and frozen-thawed human ovarian tissue xenografting and to investigate whether expression of c-kit, kit ligand (KL), and growth differentiation factor-9 (GDF-9) is maintained after freezing and xenografting of human ovarian tissue. DESIGN Prospective experimental study. SETTING Gynecology research unit in a university hospital. ANIMAL(S) Ten nude (Swiss nu/nu) 6-week-old female mice. INTERVENTION(S) The ovarian biopsy samples were obtained from six women, aged 20 to 30 years. Fresh and frozen-thawed ovarian fragments intraperitoneally grafted into nude mice for 3 weeks. MAIN OUTCOME MEASURE(S) Histologic analysis and immunohistochemical evaluation of c-kit, KL, and GDF-9 expression before and after grafting. RESULT(S) The integrity and proportion of growing follicles increased similarly in both fresh (64%) and frozen-thawed (59%) xenografts compared with non-grafted tissue (fresh: 40%; frozen-thawed: 21%). Both C-kit and KL staining were detected in the oocytes and granulosa cells of preantral follicles, and GDF-9 expression was observed in the oocytes of preantral follicles in all groups. CONCLUSION(S) Freezing does not appear to have a major impact on early follicular growth after transplantation. This study shows, for the first time, expression of c-kit, KL, and GDF-9 in human preantral follicles after ovarian tissue cryopreservation and xenotransplantation.

Abstract
BACKGROUND Female cancer patients are offered 'banking' of gametes before starting fertility-threatening cancer therapy. Transplants of fresh and frozen ovarian tissue between healthy fertile and infertile women have demonstrated the utility of the tissue banked for restoration of endocrine and fertility function. Additional methods, like follicle culture and isolated follicle transplantation, are in development. METHODS Specialist reproductive medicine scientists and clinicians with complementary expertise in ovarian tissue culture and transplantation presented relevant published literature in their field of expertise and also unpublished promising data for discussion. As the major aims were to identify the current gaps prohibiting advancement, to share technical experience and to orient new research, contributors were allowed to provide their opinioned expert views on future research. RESULTS Normal healthy children have been born in cancer survivors after orthotopic transplantation of their cryopreserved ovarian tissue. Longevity of the graft might be optimized by using new vitrification techniques and by promoting rapid revascularization of the graft. For the in vitro culture of follicles, a successive battery of culture methods including the use of defined media, growth factors and three-dimensional extracellular matrix support might overcome growth arrest of the follicles. Molecular methods and immunoassay can evaluate stage of maturation and guide adequate differentiation. Large animals, including non-human primates, are essential working models. CONCLUSIONS Experiments on ovarian tissue from non-human primate models and from consenting fertile and infertile patients benefit from a multidisciplinary approach. The new discipline of oncofertility requires professionalization, multidisciplinarity and mobilization of funding for basic and translational research.

Abstract
Cryopreservation of human gonadal tissue and oocytes has brought about new and exciting research in reproductive medicine, as well as new cryopreservation techniques that are dramatically improving post-thaw viability and freezing damage. The work done on gonadal tissues is aimed at improving the quality of life for infertile patients and for prepubertal patients undergoing gonadotoxic chemotherapy, patients for whom hormonal stimulation/IVF is not an option, and women without partners. Cryopreservation of mature oocytes is the best model for timing IVF. Vitrification is likely to benefit the field, and since 2005, implantation and pregnancy rates from vitrified oocytes have matched or eclipsed results from conventional methods, due to new cell-specific methods and formulas. Cryopreservation of immature oocytes leads to a new direction of egg banking in future. Preserving ovarian tissue for autografting is still promising and has resulted in folliculogenesis, resumed hormone production and live births in limited cases. The use of small cortical blocks, or mechanical/chemical digestion of ovarian tissue for isolation of follicles is a new direction for ovary preservation for reasons of cryoprotectant permeation and graft revascularization. Maturation of follicles in vitro has become more feasible with the use of alginate microencapsulation. Testicular tissue preservation has taken a sharp turn towards preservation of gonadal stem cells. Research into the mechanism for spermatogenesis points to the ability for male germ cells to resume spermatogenesis. The cryopreservation of minced testicular tissue for isolation of germ cells via chemical digestion has produced viable cells, however, structural damage that may be avoided by vitrification has been noted to the surrounding cell junctions and supporting cells.

Abstract
Purpose The purpose of this study was to investigate whether slow-rate freezing or vitrification is better for cryopreservation of ovary tissues pretreated with gonadotropin-releasing hormone agonist. Methods In this nonclinical study performed in rats, leuprorelin acetate was administered to female Wistar rats, aged 6-8 weeks. After confirming arrest of the estrous cycle by examination of vaginal smears, ovarian tissue was cryopreserved by vitrification and slow-rate freezing prior to thawing and autotransplantation. The time required for estrous cycle recovery was assessed from vaginal smears in each group starting from day 1 of transplantation. Estradiol levels were also monitored after transplantation. Results The estrous cycle recovered after transplantation of ovarian tissue frozen by either method, but recovery was significantly faster after transplantation of vitrified tissue. The estradiol level also recovered by 10 days after transplantation. Conclusions Ovarian function was restored after transplantation of tissue preserved by either vitrification or slow-rate freezing after pretreatment with leuprorelin acetate. This method may be applicable for patients scheduled to undergo cryopreservation of ovarian tissue before chemotherapy.

Abstract
Breast cancer is the most frequently occurring cancer in women of developed countries, and as a result of new developments in breast cancer treatment, more women are cured after being diagnosed with this disease. It is important that fertility preservation strategies are addressed before chemotherapy, because chemotherapy may induce premature ovarian failure (depending on the woman's age, the drugs used, the dosage and duration of treatment). Among possible solutions are embryos or oocytes cryopreservation, ovarian tissue cryopreservation-freezing with a subsequent orthotopic and heterotopic autotransplantation, whole ovary cryopreservation, ovarian suppression with gonadotropin-releasing hormone (GnRH) analogues, which inhibit ovarian follicular depletion induced by chemotherapeutic agents and in vitro fertilisation (IVF) after ovulation induction with aromatase inhibitors or tamoxifen.

Abstract
BACKGROUND This study was designed to assess the impact of different ovarian tissue transplantation sites on the follicular pool and ovarian tissue integrity after short-term grafting, since there is no consensus in the literature as to the optimal grafting site in experimental models. METHODS Frozen-thawed ovarian tissue from eight patients was grafted for 1 or 3 weeks to the peritoneum, inside the ovarian bursa, under the skin and into the muscle of 16 nude mice. Assessment of follicular density and follicle classification was carried out by histological analysis. Proliferative activity was evidenced by immunostaining with anti-Ki-67 antibodies, and fibrotic areas were analyzed by morphometry on histological slides. RESULTS One week post-transplantation, the proportion of Ki-67-positive primordial follicles was higher (20-42%) than in controls (1.7%), demonstrating follicular activation in all four sites. Despite this activation, primordial follicles were still found 3 weeks post-grafting, (34.1-66.9% of the follicle population), most of them quiescent, as indicated by the absence of Ki-67 immunostaining. Cryopreservation and grafting resulted in extensive fibrosis in the stroma. This fibrosis was significantly less pronounced in intramuscular (IM) grafts, representing 18.8% of the surface versus 44.7-60.5% for other sites, after 3 weeks of grafting. CONCLUSIONS All four grafting sites equally supported early follicular growth and preserved some quiescent follicles after short-term frozen-thawed human ovarian tissue transplantation. The extensive fibrosis observed does not appear to have a major impact on early follicle development, but its long-term effects must be investigated. The graft environment may be implicated in the preservation of the stroma, as suggested by a lower degree of fibrosis in the IM site.

Abstract
BACKGROUND In prepubertal and adolescent girls, fertility may be impaired by gonadotoxic treatments, repeat ovarian surgery or genetic disorders. Cryopreservation of ovarian cortex is an existing option to preserve fertility in these young girls at risk of premature ovarian failure (POF). The efficacy, feasibility and risks of ovarian cryopreservation in children must be assessed in order to validate the technique. METHODS Here, we conducted a review of ovarian cryopreservation in adults and, more specifically, in children using the PubMed databases. In addition, our own experience with ovarian cryopreservation in children was evaluated and compared with the literature. RESULTS Analysis of the literature and six published series on ovarian cryopreservation in children, as well as our own series of 58 cases, show that there is no reason to doubt its efficacy in this young population. However, no consensus has yet been reached on the indications for the technique. Indeed, with existing models, the real risk of POF may be over- or underestimated. CONCLUSION Our review suggests that ovarian cortex cryopreservation is feasible and as safe as comparable operative procedures in children. Although no births have yet resulted from freeze-thawing of prepubertal ovarian cortex, the results of this approach in adults are encouraging. However, the absence of consensus on the indications for fertility preservation, as well as the optimal timing and quantity of ovarian cortex for cryopreservation, should be taken into consideration when discussing fertility issues with girls at risk of POF and their parents.

Abstract
The applications of in vivo bioluminescent imaging (BLI) with a luciferase reporter gene occur widely across biomedical fields. Luciferase-transgenic mice are highly useful donors for tracking transplanted ovarian tissues. Realizing the full potential of this system may greatly benefit the study of the physiological behaviour and function of transplanted grafts, and the rapid and reliable evaluation of new transplantation protocols. The ovarian tissues of donor FVB/N-Tg(PolII-Luc)Ltc transgenic mice, with a luciferase transgene as the reporter, were transplanted into iso/allogeneic recipients. Rejection, ovarian function and BLI were quantitatively analysed in vivo over time. The BLI of the ovarian isografts revealed longer survival than that of allografts, even with cyclosporine A (CsA) treatment. The CD4(+)/CD8(+) ratios of peripheral T-cells were significantly reduced in allografts compared with those in isografts (P<0.0001) during rejection, whereas CD19(+) cell numbers were higher in allografts. The infiltration of CD4(+)/CD8(+) cells into the graft was unremarkable in isografts from day 1, but was strong in allografts from day 8 onwards. Hormone activity revealed complete oestrus cycles in the isografts but only the dioestrus stage in the allografts. These results demonstrate that BLI in vivo expedites the fast throughput and fate maps of ovarian grafts. The use of BLI to longitudinally monitor ovarian grafts for immunorejection demonstrated the short survival of allografts and the much longer survival of isografts. CsA treatment alone is ineffective against the acute rejection of ovarian allografts.

Abstract
Whether for the prepubertal or pubertal child, the goal of fertility preservation is to obtain cells or tissues to be used to produce future children. For the prepubertal child, preservation efforts involve germ cells, earlier forms of sperm, and immature follicles, rather than mature spermatozoa or follicles. Options for prepubertal children include for boys freezing testicular tissue and extracting testicular sperm or for girls obtaining ovarian cortical or follicular tissue for storage. These procedures involve extraction and storage of immature gametes for subsequent in vitro maturation, although attempts for sperm currently involve only animal studies. For adolescent subjects who have sufficient gonadal development and reserve, sperm, oocytes, and ovarian cortex can be retrieved as among adults.

Abstract
BACKGROUND Uterus transplantation (UTx) is developed in animal models as a future method to treat uterine factor infertility. METHODS All published studies in the area of UTx research were identified. Aspects relating to surgery, cold-ischemia/reperfusion, rejection, immunosuppression, pregnancy, ethics and institutional requirements were examined. RESULTS Uterus retrieval surgery has been solved in animals, including primates. Studies on cold-ischemia/reperfusion indicate an ischemic tolerance of >24 h. The transplantation procedure, with vascular anastomosis, has not been fully developed in animal models, indicated by frequent thrombosis formation. Pregnancies have only been reported in syngenic/auto-UTx animal models. Several ethical issues in relation to UTx, and requirements for a team that would be suitable to undertake human UTx, exist. CONCLUSION Much research on UTx has been performed in appropriate animal models. Several aspects of the procedure have been optimized but some remain to be solved. It is predicted that the research will soon reach a stage that could merit introduction of human UTx as an experimental procedure.

Abstract
BACKGROUND Women have been able to delay childbearing since effective contraception became available in the 1960s. However, fertility decreases with increasing maternal age. A slow but steady decrease in fertility is observed in women aged between 30 and 35 years, which is followed by an accelerated decline among women aged over 35 years. A combination of delayed childbearing and reduced fecundity with increasing age has resulted in an increased number and proportion of women of greater than or equal to 35 years of age seeking assisted reproductive technology (ART) treatment. METHODS Literature searches supplemented with the authors' knowledge. RESULTS Despite major advances in medical technology, there is currently no ART treatment strategy that can fully compensate for the natural decline in fertility with increasing female age. Although chronological age is the most important predictor of ovarian response to follicle-stimulating hormone, the rate of reproductive ageing and ovarian sensitivity to gonadotrophins varies considerably among individuals. Both environmental and genetic factors contribute to depletion of the ovarian oocyte pool and reduction in oocyte quality. Thus, biological and chronological ovarian age are not always equivalent. Furthermore, biological age is more important than chronological age in predicting the outcome of ART. As older patients present increasingly for ART treatment, it will become more important to critically assess prognosis, counsel appropriately and optimize treatment strategies. Several genetic markers and biomarkers (such as anti-Müllerian hormone and the antral follicle count) are emerging that can identify women with accelerated biological ovarian ageing. Potential strategies for improving ovarian response include the use of luteinizing hormone (LH) and growth hormone (GH). When endogenous LH levels are heavily suppressed by gonadotrophin-releasing hormone analogues, LH supplementation may help to optimize treatment outcomes for women with biologically older ovaries. Exogenous GH may improve oocyte development and counteract the age-related decline of oocyte quality. The effects of GH may be mediated by insulin-like growth factor-I, which works synergistically with follicle-stimulating hormone on granulosa and theca cells. CONCLUSION Patients with biologically older ovaries may benefit from a tailored approach based on individual patient characteristics. Among the most promising adjuvant therapies for improving ART outcomes in women of advanced reproductive age are the administration of exogenous LH or GH.

Abstract
Ovarian tissue cryopreservation and transplantation can be used to preserve fertility for cancer patients. In this study, we assessed the viability and function of ovarian tissue from adult mice that was cryopreserved by solid surface vitrification or traditional slow-cooling using variousin vitroandin vivotechniques, including allotransplantation,in vitrooocyte maturation, embryo culturein vitro, blastocyst cryopreservation, embryo transfer, and development. The importance of cumulus cells for oocyte maturation, fertilization, and embryo development was investigated. Graft recovery, follicle survival, and oocyte retrieval was similar in control, vitrified, and slow-cooled groups. High rates of oocyte maturation, cleavage, and blastocyst formation were achieved, with no significant differences between the control, vitrified or slow-cooled ovarian tissue grafts. The presence of cumulus cells was important for oocyte maturation, fertilization, and subsequent development. Cumulus–oocyte complexes with no surrounding cumulus cells (N-COCs) or with an incomplete layer (P-COCs) had significantly lower rates of oocyte maturation and blastocyst formation than cumulus–oocyte complexes with at least one complete layer of cumulus cells (F-COCs; maturation rate: 63, 78 vs 94%; blastocyst rate: 29, 49 vs 80%). Live births were achieved using vitrified blastocysts derived from oocytes taken from vitrified and slow-cooled ovarian tissue heterotypic allografts. Successful production of healthy offspring from these vitrified blastocysts suggests that this technique should be considered as a useful stage to pause in the assisted reproduction pathway. This provides an alternative protocol for restoring fertility and offering cancer patients a better indication of their chances of pregnancy and live birth.

Abstract
Certain forms of treatment for cancer in children and adolescents may significantly affect their fertility. Oncologists and specialists in reproductive medicine are attempting to use various methods of fertility preservation to address this problem. However, major medical/biological issues must be resolved before many of these methods can be considered accepted medical treatments. In addition, ethical considerations that such treatments bring to the fore, including those relevant to assent by children and the provision of experimental treatment to children, must be taken into account. This article addresses the current and future medical and ethical status of the development of fertility-preserving treatment for adolescents and children who are to receive cancer treatment.

Abstract
There are several methods of fertility preservation available for female patients facing infertility following gonadotoxic treatment of cancer or systemic disease. Embryos, oocytes or ovarian tissue can be cryopreserved and stored until the time when the patient is cured of her main disease and is expecting parenthood. The individual's choice depends on the nature and stage of the main disease, expected treatment, their condition, and age and existence of the partner. It is important to inform all such women about the options, and together with them, choose the most appropriate ones. It is often possible to save ovarian tissue even though the first chemotherapy courses have been undergone, but many more follicles can be stored before cancer treatment.

Abstract
Cryopreservation as a process can be divided into two methods: conventional freezing and vitrification. The high effectiveness of vitrification in comparison with conventional freezing for human oocytes and embryos is shown, whereas data on human ovarian tissue are limited. The aim of this study was to compare the safety and effectiveness of conventional freezing and vitrification of human ovarian tissue. Ovarian tissue fragments from 15 patients were transported to the laboratory within 22–25 h in a special, isolated transport box that can maintain a stable temperature of between 5 and 8 °C for 36 h. Small pieces of ovarian tissue (0.3–1×1–1.5×0.7–1 mm) were randomly distributed into three groups: group 1, fresh pieces immediately after receiving transport box (control); group 2, pieces after vitrification; and group 3, pieces after conventional freezing. After thawing, all the pieces were culturedin vitro. The viability and proliferative capacity of the tissue byin vitroproduction of hormones, development of follicles, and glyceraldehyde 3-phosphate dehydrogenase (GAPDH) gene expression after culture were evaluated. A difference between freezing and vitrification was not found in respect to hormonal activity and follicle quality. The supernatants showed 17-β estradiol concentrations of 365, 285, and 300 pg/ml respectively, and progesterone concentrations of 3.82, 1.99, and 1.95 ng/ml respectively. It was detected that 95, 80, and 83% follicles respectively were morphologically normal. The molecular biological analysis, however, demonstrated that theGAPDHgene expression in ovarian tissue after vitrification was dramatically decreased in contrast to conventional freezing. For cryopreservation of human ovarian tissue, conventional freezing is more promising than vitrification, because of higher developmental potential.

Abstract
Cryopreservation of human cells and tissue has generated great interest in the scientific community since 1949, when the cryoprotective activity of glycerol was discovered. Nowadays, it is possible to reach the optimal conditions for the cryopreservation of a homogeneous cell population or a one cell-layer tissue with the preservation of a high pourcentage of the initial cells. Success is attained when there is a high recovery rate of cell structures and tissue components after thawing. It is more delicate to obtain cryopreservation of composite tissues and much more a whole organ. The present work deals with fundamental principles of the cryobiology of biological structures, with special attention to the transfer of liquids between intra and extracellular compartments and the initiation of the formation and aggregation of ice during freezing. The consequences of various physical and chemical reactions on biological tissue are described for different cryoprotective agents. Finally, we report a review of results on cyropreservation of various tissues, on the one hand, and various organs, on the other. We also report immunomodulation of antigenic responses to cryopreserved cells and organs.

Abstract
BACKGROUND Transplantation of ovarian tissue is, at present, the only clinical option available to restore fertility using cryopreserved ovarian tissue. More than 30 transplantations of cryopreserved tissue have been reported, and six babies have been born, worldwide, following this procedure. Despite these encouraging results, it is essential to optimize the procedure by improving the follicular survival, confirming safety and developing alternatives. Here, we review the different factors affecting follicular survival and growth after grafting. METHODS Relevant studies were identified by searching Pubmed up to January 2009 with English language limitation. The following key words were used: (ovarian tissue or whole ovary) AND (transplantation) AND (cryopreservation or pregnancy). Using the literature and personal experience, we examined relevant data on the different exogenous and clinical factors affecting follicular development after grafting. RESULTS Clinical factors such as the patient's age and the transplantation sites influenced the lifespan of the graft. A heterotopic transplantation site is not optimal but offers some advantages and it may also promote the hormonal environment after a combined heterotopic and orthotopic transplantation. Exogenous factors such as antioxidants, growth factors or hormones were tested to improve follicular survival; however, their efficiency regarding further follicular development and fertility potential remains to be established. CONCLUSION Additional evidence is required to define optimal conditions for ovarian tissue transplantation. Alternatives such as whole ovary or isolated follicles transplantations require further investigation but are likely to be successful in humans in the future.

Abstract
BACKGROUND With advances in treatment, the number of young cancer survivors who may benefit from fertility preservation is growing. The aim of this study was to review the literature investigating psychological aspects of fertility issues and fertility preservation in patients undergoing fertility-compromising therapy for cancer or other life-threatening diseases, previous to or during their reproductive lifespan. METHODS Articles were identified in PubMed, Embase and PsycLIT as well as manually retrieved from literature citations for the time period from 1999 to 2008. Inclusion criteria were (i) qualitative or quantitative design, (ii) focus on patients previous to or during their reproductive lifespan and (iii) dealing with aspects such as (1) impact of fertility issues in cancer patients or (2) health professionals' and/or patients' attitudes towards fertility preservation or (3) counselling. RESULTS Twenty-four studies were identified. According to the studies on aspect (1), fertility is an important issue for cancer patients. Health professionals as well as patients and parents consider fertility preservation as an important option for young cancer patients; all parties involved, however, were noted to have knowledge and information deficits. Patients recalling counselling about the impact of cancer treatment on fertility ranged from 34% to 72%. Counselling is far from being offered globally to all patients at risk, and providing information seems to be selective. CONCLUSIONS The existing literature demonstrates the need for and the limits of current counselling. Future research should target the means to facilitate the decision-making process for patients and health professionals.

Abstract
The FOXL2 gene is one of 10 forkhead genes, the mutations of which lead to human developmental disorders, often with ocular manifestations. Mutations in FOXL2 are known to cause blepharophimosis syndrome (BPES), an autosomal dominant eyelid malformation associated (type I) or not (type II) with ovarian dysfunction, leading to premature ovarian failure (POF). In addition, a few mutations have been described in patients with isolated POF. Here, we review all currently described FOXL2 sequence variations and genomic rearrangements in BPES and POF. Using a combined mutation detection approach, it is possible to identify the underlying genetic defect in a major proportion (88%) of typical BPES patients. Of all genetic defects found in our BPES cohort, intragenic mutations represent 81%. They include missense changes, frameshift and nonsense mutations, in-frame deletions, and duplications, that are distributed along the single-exon gene. Genomic rearrangements comprising both deletions encompassing FOXL2 and deletions located outside its transcription unit, represent 12% and 5% of all genetic defects in our BPES cohort, respectively. One of the challenges of genetic testing in BPES is the establishment of genotype-phenotype correlations, mainly with respect to the ovarian phenotype. Genetic testing should be performed in the context of genetic counseling, however, and should be systematically complemented by a multidisciplinary clinical follow-up. Another challenge for health care professionals involved in BPES is the treatment of the eyelid phenotype and the prevention or treatment of POF.

Abstract
BACKGROUND Cryopreservation of whole ovaries followed by vascular transplantation may improve long-term function in comparison to conventional cryopreservation of ovarian cortex and avascular transplantation. The aim of this study was to assess methods for the evaluation of viability and function of frozen-thawed whole ovaries. METHODS Ewe ovaries were flushed with either cryoprotectant (propandiol: FROZEN-PROH) or Ringer Acetate (FROZEN-RA) followed by slow freezing. Some ovaries were assessed fresh after flushing with Ringer Acetate (FRESH-RA). Assessment was done by light microscopy, biochemical response (cyclic adenosine 3',5'-monophosphate (cAMP) and steroids) during in vitro perfusion with forskolin, viability assay and cell culture. RESULTS Microscopy showed well-preserved morphology with the presence of small follicles in all groups before perfusion. Stromal oedema was seen after in vitro perfusion of FROZEN ovaries, and shrunken small follicles were seen only in FROZEN-RA at the end of perfusion. During in vitro perfusion, FRESH-RA ovaries responded with large increase in levels of cAMP after stimulation with forskolin. FROZEN-PROH and FROZEN-RA ovaries exhibited lower production of cAMP. Progesterone concentrations in cell cultures of dispersed ovarian cells were higher in FRESH-RA when compared with FROZEN groups. Addition of hCG to cell cultures resulted in higher progesterone levels in the FROZEN-PROH compared with FROZEN-RA. Cell viability assay showed overall viability of 60-75% with no significant difference between groups. CONCLUSION In vitro perfusion may prove to be a suitable method to test viability and function of frozen-thawed whole ovaries contributing to the optimization of current cryopreservation protocols.

Abstract
PURPOSE Cancer treatments for young women can permanently or temporarily affect fertility. The purpose of this retrospective analysis was to present the clinical experience and ethical considerations of fertility preservation in female oncology patients in a tertiary gynaecological department. METHODS Since 2002, in 37 patients fertility preservation was performed according to an institutional review board approved protocol in a University hospital in the Netherlands; 33 patients were not treated. RESULTS Embryo cryopreservation was performed in 10 patients, ovarian tissue cryopreservation in 24, and an ovarian transposition was performed in 3 patients; in one patient combined with an ovarian transplantation and in one patient with ovarian tissue cryopreservation. DISCUSSION Approved protocols and timing are essential in performing female fertility preservation. Referral for ovarian tissue and embryo cryopreservation is minimal in the Netherlands. Future research focuses on the psychosocial aspects of fertility preservation and explores patients' and professionals' expectations and attitudes regarding fertility preservation and aims to be in line with technical developments.
