Abstract
RESEARCH QUESTION What are the parameters of age, indications for ovarian tissue cryopreservation, storage characteristics and reasons for tissue disposal in a large cohort of individuals undertaking cryopreservation? DESIGN The relevant parameters in a single university centre were revised and digitalized in the period from 2019 to 2021. To assess patients' motivation at the end of storage, patients were contacted by letter, e-mails and telephone calls. RESULTS A group of 2475 patients with stored ovarian tissue were analysed in the time period between 2000 and 2021; the response rate for contact calls and letters was 28.8% (224/777). Where storage had ended (n = 1155), patients had on average stored for 3.8 years and begun storing at age 30 years; the main indications were breast cancer (53%) and lymphoma (17.5%). Of these participants, 2.5% had a transplantation on site, 10.3% transferred their tissue to another cryobank and 11.5% were deceased. The majority of the group (75.7%) ended their storage due to pregnancy (49.1%), a lack of desire to have children (25.9%), storage fees that were too expensive (8.9%), death (8.5%), recurrence of cancer (8.5%), lack of a partner (4%) and fear of surgery in the future (3.1%); 6.7% retrospectively regretted ending storage. CONCLUSIONS The pregnancy rate of 49.1%, resulting from ovarian tissue that was not removed during surgery for scheduled ovarian tissue cryopreservation supports the clinical approach of removing and cryopreserving only 25-50% of one ovary. It is proposed that interdisciplinary counselling should be implemented not only prior to fertility preservation, but also when intending to end storage.

Abstract
In 2020, the estimated number of new leukemia cases was higher than 30,000 in girls between 0 and 19 years old. Due to cancer treatment, some of these patients may lose both endocrine and reproductive functions. Transplantation of cryopreserved ovarian tissue is not advised after cancer remission because it has a high risk of reintroducing malignant cells in the patient, potentially leading to leukemia recurrence. To safely transplant the ovarian tissue from these patients and restore their fertility, our goal was to develop a photodynamic therapy (PDT) strategy to eliminate leukemia ex vivo. To this end, we designed, optimized, and characterized OR141-loaded niosomes (ORN) to develop the most effective formulation for ex vivo purging ovarian fragments from chronic myelogenous leukemia cells. After establishing the best ORN formulation, the PDT efficiency of optimized ORN was determined for human ovarian stromal cells and acute myeloid leukemia cell line (HL60). Blank niosomes treatment on ovarian stromal cells causes no significant toxicity, showing that the composition of the nanoparticle is not toxic. On the other hand, the in vitro studies showed that while ovarian stromal cells were still viable (82.04 ± 2.79%) after the treatment by 0.5 µM ORN, the same treatment yielded 95.43 ± 3.89% toxicity and cell death in the cancer cells. In conclusion, our results showed that our novel PDT procedure could be a promising strategy to destroy leukemia cells in ovarian tissue fragments allowing safe transplantation in cancer survivors.

Abstract
The field of photodynamic therapy (PDT) for treating various malignant neoplasms has been given researchers' attention due to its ability to be a selective and minimally invasive cancer therapy strategy. The possibility of tumor cell infection and hence high recurrence rates in cancer patients tends to restrict autologous transplantation. So, the photodynamic tissue purging process, which consists of selective photoinactivation of the malignant cells in the graft, is defined as a compromising strategy to purify contaminated tissues before transplantation. In this strategy, the direct malignant cells' death results from the reactive oxygen species (ROS) generation through the activation of a photosensitizer (PS) by light exposure in the presence of oxygen. Since new PS generations can effectively penetrate the tissue, PDT could be an ideal ex vivo tissue purging protocol that eradicates cancer cells derived from various malignancies. The challenge is that the applied pharmacologic ex vivo tissue purging should efficiently induce tumor cells with minor influence on normal tissue cells. This review aims to provide an overview of the current status of the most effective PDT strategies and PS development concerning their potential application in ex vivo purging before hematopoietic stem cell or ovarian tissue transplantation.

Abstract
Background Despite its clinical success rates, transplantation after ovarian tissue cryopreservation (OTC) remains a matter of concern. Certain cancer subtypes may lead to the transfer of malignant cells when transplantation of affected ovarian tissue is conducted. IVG and subsequent isolation of vital follicles obtained from frozen thawed ovarian tissue for further in vitro maturation (IVM) would expand current fertility protection techniques while reducing the risk of retransplanting malignant cells. Methods A total of 216 cortical biopsies from 3 patients were included in this study in 4 treatment groups. After freezing, thawing and 8 days of hypoxic tissue culture supplemented with different concentrations of human follicular fluid (HuFF) and follicle-stimulating hormone (FSH), follicles were isolated enzymatically and stained with calcein to determine follicular viability. Numbers and size of vital follicles were assessed by fluorescence microscopy (Ti2, Nikon) and specified by computer assisted, semi-automated measurement (NIS software, Nikon). To estimate the effect of in vitro culture on apoptosis, tissue sections were stained for nicked DNA (TUNEL) prior and after tissue culture. Results Analysing 3025 vital follicles, we observed significant differences [P < 0.01] regarding follicle size when hypoxic tissue culture was supplemented with HuFF compared with the control group on day 1, individual follicles reached sizes > 100 µm. Conclusions The results implicate that HuFF contains valuable factors contributing to significant IVG of follicles in human ovarian tissue and could be regarded as an additional tool in personalized fertility restoration prior to retransplantation of ovarian tissue.

Abstract
Age-related fertility decline (ARFD) is a prevalent concern amongst western cultures due to the increasing age of first-time motherhood. Elective oocyte and embryo cryopreservation remain the most established methods of fertility preservation, providing women the opportunity of reproductive autonomy to preserve their fertility and extend their childbearing years to prevent involuntary childlessness. Whilst ovarian cortex cryopreservation has been used to preserve reproductive potential in women for medical reasons, such as in pre- or peripubertal girls undergoing gonadotoxic chemotherapy, it has not yet been considered in the context of ARFD. As artificial reproductive technology (ART) and surgical methods of fertility preservation continue to evolve, it is a judicious time to review current evidence and consider alternative options for women wishing to delay their fertility. This article critically appraises elective oocyte cryopreservation as an option for women who use it to mitigate the risk of ARFD and introduces the prospect of elective ovarian cortex cryopreservation as an alternative.

Abstract
Background: The survival rate of cancer patients is increasing owing to the early diagnosis and treatment methods. Radiotherapy and chemotherapy may cause serious complications, such as ovarian failure and infertility. In particular, preservation of fertility in women of reproductive age with cancer could improve their quality of life as well as reduce social and psychological pain.Current Concepts: Embryo or oocyte cryopreservation is a method of fertility preservation; however, it cannot be utilized by all women with cancer because of the complications of the condition and treatment method. Ovarian tissue cryopreservation and transplantation enables fertility preservation in those needing immediate cancer treatment, such as chemotherapy or radiotherapy, or those unqualified for ovarian stimulation. A recent review reported that frozen-thawed ovarian transplantation led to approximately 130 live births with a conception rate of approximately 30%. Endocrine function recovery occurred in 92.9% of the patients between 3.5 and 6.5 months after transplantation.Discussion and Conclusion: In this study, we introduced various methods and strategies for improving the outcomes of ovarian tissue cryopreservation and transplantation. These results could serve as a reference for patients and clinicians to choose the best options for fertility preservation based on the patient’s current situation and condition.

Abstract
In recent decades, there has been increasing attention toward the quality of life of breast cancer (BC) survivors. Meeting the growing expectations of fertility preservation and the generation of biological offspring remains a great challenge for these patients. Conventional strategies for fertility preservation such as oocyte and embryo cryopreservation are not suitable for prepubertal cancer patients or in patients who need immediate cancer therapy. Ovarian tissue cryopreservation (OTC) before anticancer therapy and autotransplantation is an alternative option for these specific indications but has a risk of retransplantation malignant cells. An emerging strategy to resolve these issues is by constructing an artificial ovary combined with stem cells, which can support follicle proliferation and ensure sex hormone secretion. This promising technique can meet both demands of improving the quality of life and meanwhile fulfilling their expectation of biological offspring without the risk of cancer recurrence.

Abstract
Due to the risk of reintroducing malignant cells, autotransplantation of cryopreserved ovarian tissue is not allowed in leukemia patients. In order to restore fertility in these patients, ex vivo purging of ovarian fragments could be proposed as a strategy to eradicate malignant cells before grafting. Photodynamic therapy (PDT), as a clinical-approved modality, is a minimally invasive and selective therapeutic for eliminating malignant cells. The present work aims therefore to evaluate the phototoxicity of two photosensitizers (aluminum phthalocyanine (AlPc) and zinc phthalocyanine (ZnPc)) on leukemia cells. To this end, two lines of malignant cells (K562 and HL-60) and isolated ovarian stromal cells (control) were treated by PDT using a diode laser with various energy densities. Cell viability after the treatment, the amount of generated reactive oxygen species, dark toxicity of the photosensitizers, and single-cell morphology were studied. Our results demonstrated that using irradiation with the energy density of 10 J/cm2, 1 µM AlPc could significantly reduce the viability of K562 (4.73 ± 0.14%) and HL-60 (2.74 ± 0.31%). Similarly, the viability of these cells was reduced (K562 cells: 3.84 ± 0.81%; HL-60 cells: 6.82 ± 3.21%) with 1 µM ZnPc and an energy density of 50 J/cm2. On the other hand, these PDT protocols had no significant effect on stromal cells. These findings indicate that our approach can be a promising strategy for the safe restoration of fertility in leukemia patients. However, further studies are necessary to assess its efficiency in ovarian fragments containing malignant cells to determine their eradication rate and the effect of our treatment on the survival of stromal cells and preantral follicles.

Abstract
Chemotherapy and radiotherapy improved survival rates of patients with cancer. However, they can cause ovarian failure and infertility in women of reproductive age. Infertility following cancer treatment is considered a major quality of life issue. Ovarian tissue cryopreservation and transplantation is an important option for fertility preservation in adult patients with cancer who need immediate chemotherapy or do not want to undergo ovarian stimulation. Ovarian tissue freezing is the only option for preserving the fertility of prepubertal patients with cancer. In a recent review, it was reported that frozen-thawed ovarian transplantation has lead to about 90 live births and the conception rate was about 30%. Endocrine function recovery was observed in 92.9% between 3.5 and 6.5 months after transplantation. Based on our review, ovarian tissue cryopreservation and transplantation may be carefully considered before cancer treatment in order to preserve fertility and endocrine function in young cancer survivors.

Abstract
PURPOSE Few clinical options for fertility preservation are available to females with cancer, and data about clinical outcomes is limited. Potential supplementary approaches to fertility preservation include retrieval of immature oocytes followed by in vitro maturation (IVM) and storage. The aim of this study was to evaluate post-thawing outcomes of immature oocytes collected both by transvaginal aspiration and from excised ovarian tissue. METHODS We conducted a retrospective cohort study of patients treated in a single tertiary center. We reviewed the records of 119 cancer patients who underwent ovarian tissue cryopreservation and immature oocyte harvesting for fertility preservation. All embryos and oocytes that were frozen and thawed were included in the study. Post-thawing outcomes were evaluated. RESULTS Thirty-five stored embryos from eight patients were thawed. Twenty-nine embryos survived (82% survival rate) and were transferred. Six oocytes were thawed, two oocytes survived, and no oocytes were fertilized. Only one PCOS patient became pregnant, resulting in the normal delivery of a healthy baby. CONCLUSIONS Although a relatively high number of mature oocytes and embryos can be stored with the combined procedure, the limited rate of pregnancies represents a poor reproductive outcome. Therefore, this approach should be reserved for special groups with limited options.

Abstract
The efficiency of oocyte in-vitro maturation (IVM) and vitrification procedures after ex-vivo collection from ovarian tissue were assessed according to patient age, number of retrieved oocytes and tissue transport conditions. The combined procedure was performed in 136 patients: 130 adults (mean 27.6 ± 5.6 years) and six prepubertal girls (mean 8.7 ± 2.3 years). A higher mean number of oocytes were collected in girls compared with adults (11.5 ± 8.0 versus 3.8 ± 4.2, respectively, P < 0.001) but the percentage of degenerated oocytes was significantly higher in girls (35.5% versus 17.1%, respectively, P < 0.001). IVM rates were significantly lower in prepubertal than postpubertal population (10.3% versus 28.1%, P = 0.002). In adults, a negative correlation was observed between number of retrieved oocytes and age (P = 0.002; r = -0.271); the correlation was positive between anti-Müllerian hormone (AMH) and number of collected oocytes (P = 0.002; r = 0.264). IVM rates were not correlated with AMH levels (r = 0.06) or age (r = -0.033). At present, nine oocytes and one embryo have been warmed in four patients and one biochemical pregnancy obtained. This suggests the combined procedure could be an additional option for fertility preservation.

Abstract
Patients affected with severe endometriosis are at significant risk for ovarian tissue damage, which may lead to infertility, reduced response to ovarian stimulation, and occasionally, premature ovarian failure. The risk for a compromised ovarian reserve in young patients is especially high following repeated surgical intervention and in the presence of bilateral endometriomas. In many cases, enhanced loss of ovarian reserve may also result from the damaging effect of the pathologic process on follicle reservoir even without surgical interventions. Women diagnosed with severe endometriosis and those designated for extensive ovarian surgical intervention are frequently not planning to conceive. In light of recent advances in fertility preservation techniques (FPT), such as oocytes and ovarian tissue freezing, as well as their increasing success rates, we critically evaluate the options for FPT in patients suffering from endometriosis. Personalized counseling should be offered to all patients with endometriosis taking into account age, extent of ovarian involvement, current ovarian reserve, previous and impending surgeries for endometriosis, along with current success rates and possible risks associated with FPT.

Abstract
OBJECTIVE To review the literature and to present the latest advances in the autotransplantation of cryopreserved ovarian tissue. MATERIALS AND METHODS A literature review was conducted for all relevant articles assessing the fertility preservation, ovarian tissue transplantation, standard freezing and vitrification of ovarian tissue. RESULTS One of the promising and effective methods for fertility preservation may be the autotransplantation of cryopreserved ovarian tissue. At present, 30 babies have been born after orthotopic autotransplantation of frozen-thawed human ovarian tissue. Restoration of ovarian activity occurs between 3.5 months and 6.5 months. The longevity of autotransplanted ovarian tissue is about 5-7 years. The follicles are similarly preserved after all freezing methods; however, the ovarian stroma is significantly better preserved after vitrification than after slow freezing. An important topic for further research is preparation of the "vascular bed", optimization of vitrification technique and the development of alternative procedures to avoid the transmission of cancer cells via ovarian tissue autotransplantation - "artificial ovary". CONCLUSIONS Cryopreservation of ovarian tissue has unique advantages over other strategies. This method: (1) does not delay cancer treatment; (2) is safer for hormone dependent malignancy; (3) can be done independent of menstrual cycles; (4) is the only option for prepubertal girls; (5) can restore not only fertility but endocrine function.

Abstract
OBJECTIVE To quantify the number of follicles in patients with ovarian pathologies, benign and malignant, in pregnant and nonpregnant states and to determine how the presence of ovarian masses and BRCA status affects follicular counts. MATERIALS AND METHODS Slides from 134 reproductive-aged women undergoing oophorectomy were examined using light microscopy by 3 independent counters blinded to the diagnosis. In all, 20 patients had cancer, 69 had benign conditions, and 35 patients were BRCA+ or had a strong family history of breast and/or ovarian cancer. In all, 10 women were either pregnant or immediately postpartum. RESULTS Patients undergoing risk-reducing surgery had significantly decreased follicle count compared to physiologic control. Patients with cancer had significantly decreased counts compared to all other groups. There were no differences within the benign cohort. CONCLUSIONS When compared to benign masses, the cortex surrounding an ovarian malignancy has decreased follicle density. The stretch impact may minimize any impact on total follicle numbers. Furthermore, there may be a proliferation of ovarian stroma, with the same number of follicles spread over a larger surface area. This information is important when counseling women with ovarian masses regarding the use of ovarian tissue cryopreservation.

Abstract
BACKGROUND Cancer can be a devastating diagnosis. In particular, malignancy and its indicated treatments have profoundly negative effects on the fertility of young cancer patients. Oncofertility has emerged as a new interdisciplinary field to address the issue of gonadotoxicity associated with cancer therapies and to facilitate fertility preservation. In Canada, these fertility issues are often inadequately addressed despite the availability of resources. The goal of this four-part series is to facilitate systemic improvements in fertility preservation for adolescent and young adult Canadians with a new diagnosis of cancer. METHODS This article reviews fertility preservation options that use cryopreservation techniques. It also outlines some of the alternative options for future parenthood. RESULTS Cryopreservation of a woman's gametes and gonadal tissue may involve embryo, oocyte, and ovarian tissue cryopreservation with or without ovarian stimulation. Similarly, male gametes and gonadal tissue may be cryopreserved. Techniques and success rates continue to improve. Third-party assistance through gamete donation, gestational carriers, and adoption are also alternative options for parenthood. CONCLUSIONS Cryopreservation techniques are especially feasible options for fertility preservation in the newly diagnosed cancer patient.

Abstract
STUDY QUESTION What are the effects of thin ovarian grafts compared with grafts of the standard thickness on follicle loss post-transplantation? SUMMARY ANSWER Transplantation of reduced-thickness ovarian grafts led to intense activation and 'burn-out' a short time after transplantation resulting in significant folllicle loss. WHAT IS KNOWN ALREADY Transplantation of fresh and frozen-thawed ovarian tissue has been proved successful, but techniques vary and are not optimised, often resulting in significant follicular loss. Follicle loss is mostly related to the freezing-thawing process and to post-transplantation hypoxia. STUDY DESIGN, SIZE, DURATION Bovine ovarian tissue strips (n = 55) were prepared in two groups of conventional-thickness strips (1-2 mm) or thin strips (0.5-0.9 mm). Fresh or frozen-thawed samples were xenotransplanted into sterilized immune-deficient mice (n = 49). Non-transplanted conventional size fresh samples were used as controls (n = 6). Grafts from all study groups were recovered after 7 days for analysis. PARTICIPANTS/MATERIALS, SETTING, METHODS Morphometric differential counting of follicle classes was performed by two observers. Immunohistochemistry was conducted for proliferation (Ki67), cortical fibrosis (Masson tri-chrome) and blood-vessel density (CD31). Results were expressed as the mean number of dormant or growing follicle (GF) type per section or total follicle counts per graft. Blood-vessel density was calculated per mm(2). P-values <0.05 were considered statistically significant. MAIN RESULTS AND THE ROLE OF CHANCE The loss of all follicle types, and most noteably of primordial follicles (PMFs), was observed 7 days post-transplantation (P < 0.05). The relatively high number of GFs and the positive Ki67 staining in all recovered grafts indicated that follicle activation was depleting the resting follicle pool. The reduced graft thickness had an adverse effect on the number of recovered follicles, especially on the resting non-GFs in the fresh, and more so in the frozen-thawed, samples (P < 0.05). Extensive stromal fibrosis and high blood-vessel density were observed in all grafts with no advantage in the thin prepared grafts. LIMITATIONS, REASONS FOR CAUTION This study used only one species of ovaries (bovine) for xenotransplantation. The immediate post-transplantation events were not visualized directly nor were the molecules involved in follicle activation studied. WIDER IMPLICATIONS OF THE FINDINGS Follicle activation and 'burn-out' appear to be important in follicle loss after transplantation. Reducing graft thickness in an attempt to improve freezing conditions and reduce post-transplantation ischemia has adverse effects on the graft follicle pool due to increased activation and loss. Agents which prevent 'burn-out' will potentially improve follicle pool survival. STUDY FUNDING/COMPETING INTEREST(S) This study was funded by research grants from the Israeli Science Foundation (No. 1675/10), the Israeli Jack Craps foundation and the Israel Cancer Research Fund (ICRF No. 12-3081). The authors have no competing interest to declare.

Abstract
With broadening indications, more options for hematopoietic cell transplantation (HCT) and improvement in survival, the number of long-term HCT survivors is expected to increase steadily. Infertility is a frequent problem that long-term HCT survivors and their partners face and it can negatively impact on the quality of life. The most optimal time to address fertility issues is before the onset of therapy for the underlying disease; however, fertility preservation should also be addressed before HCT in all children and patients of reproductive age, with referral to a reproductive specialist for patients interested in fertility preservation. In vitro fertilization (IVF) and embryo cryopreservation, oocyte cryopreservation and ovarian tissue banking are acceptable methods for fertility preservation in adult women/pubertal females. Sperm banking is the preferred method for adult men/pubertal males. Frequent barriers to fertility preservation in HCT recipients may include the perception of lack of time to preserve fertility given an urgency to move ahead with transplant, lack of patient-physician discussion because of several factors (for example, time constraints, lack of knowledge), inadequate access to reproductive specialists, and costs and lack of insurance coverage for fertility preservation. There is a need to raise awareness in the medical community about fertility preservation in HCT recipients.

Abstract
Previous studies provided inconclusive evidence for the effectiveness of gonadotropin-releasing hormone analogue on ovarian function protection against chemotherapy-induced genotoxicity in premenopausal patients. This study was designed to examine the efficacy of leuprolide acetate on ovarian function preservation in patients with breast cancer. A total of 220 patients were recruited in this prospective clinical trial and were assigned randomly to receive cyclophosphamide-doxorubicin-based chemotherapy only or chemotherapy plus leuprolide acetate. Resumption of menses or premenopausal levels of both follicle-stimulating hormone (FSH) and estradiol (E2) within 12 months after the end of chemotherapy were considered as effective ovarian preservation. A total of 183 patients were considered evaluable (94 in chemotherapy-only group and 89 in chemotherapy plus leuprolide acetate group). At the end of follow-up, 27 patients in chemotherapy group and 15 in chemotherapy plus leuprolide acetate group resumed menses; seven patients in chemotherapy group and 14 in chemotherapy plus leuprolide acetate group restored premenopausal levels of FSH and E2. The median time to resume menses was 9.2 months for patients in chemotherapy plus leuprolide acetate group and was not reached in chemotherapy-only group. In addition, our results demonstrated that age and chemotherapy doses made no significant difference in the occurrence of premature menopause. The leuprolide acetate treatment simultaneously with cyclophosphamide-doxorubicin-based chemotherapy reduced the risk of developing premature menopause in premenopausal patients with breast cancer.

Abstract
OBJECTIVE To compare conventional slow equilibrium cooling and directional freezing for cryopreservation of whole ovaries. DESIGN Experimental animal study. SETTING Academic research environment. ANIMAL(S) Adult ewes. INTERVENTION(S) Eighty-one ovaries were randomly assigned to fresh control, conventional freezing (CF), and directional freezing (DF) group. Ovaries of CF and DF groups were perfused via the ovarian artery with Leibovitz L-15 medium, 10% fetal bovine serum, and 1.5 M dimethyl sulfoxide for 5 minutes. Each ovary was inserted into a glass test tube containing 10 mL of the same solution and cooled to -100°C or -70°C, respectively. Ovaries were stored in liquid nitrogen for a minimum of 2 weeks. MAIN OUTCOME MEASURE(S) Structural integrity of cortical and medulla regions, vascular integrity, follicle in vitro development, cell proliferation, and DNA damage and repair. RESULT(S) All examined parameters indicate that the structure of DF ovaries remains largely intact and comparable to fresh controls, whereas significant damages were observed in CF ovaries. CONCLUSION(S) Directional freezing allows good preservation of whole ovaries, with most of the parameters taken into consideration almost identical to those recorded in fresh control samples. This encourages a reconsideration of the possible use of whole-ovary cryopreservation as a viable alternative to cortical fragments.

Abstract
BACKGROUND The risk of recurrent oncological disease due to the reintroduction of cancer cells via autotransplantation of cryopreserved ovarian tissue is unknown. METHODS A systematic review of literature derived from MEDLINE, EMBASE and the Cochrane Library was conducted. Studies on follow-up after autotransplantation; detection of cancer cells in ovarian tissue from oncological patients by histology, polymerase chain reaction or xenotransplantation; and epidemiological data on ovarian metastases were included. RESULTS A total of 289 studies were included. Metastases were repeatedly detected in ovarian tissue obtained for cryopreservation purposes from patients with leukaemia, as well as in one patient with Ewing sarcoma. No metastases were detected in ovarian tissue from lymphoma and breast cancer patients who had their ovarian tissue cryopreserved. Clinical studies indicated that one should be concerned about autotransplantation safety in patients with colorectal, gastric and endometrial cancer. For patients with low-stage cervical carcinoma, clinical data were relatively reassuring, but studies focused on the detection of metastases were scarce. Oncological recurrence has been described in one survivor of cervical cancer and one survivor of breast cancer who had their ovarian tissue autotransplanted, although these recurrences may not be related to the transplantation. CONCLUSIONS It is advisable to refrain from ovarian tissue autotransplantation in survivors of leukaemia. With survivors of all other malignancies, current knowledge regarding the safety of autotransplantation should be discussed. The most reassuring data regarding autotransplantation safety were found for lymphoma patients.

Abstract
Chemotherapy has the potential to deplete and destroy a woman’s reproductive potential. Although many oncologists are referring women for fertility preservation before chemotherapy, in many cases there is limited time for fertility preservation. This review provides an overview of the impact of cancer and chemotherapy on the ovarian reserve, a summary of methods of fertility preservation prior to chemotherapy, and current knowledge of fertility preservation techniques after gonadotoxic chemotherapy.

Abstract
Background. While assisted reproductive technology (ART), including in vitro fertilization has given hope to millions of couples suffering from infertility, it has also introduced countless ethical, legal, and social challenges. The objective of this paper is to identify the aspects of ART that are most relevant to present-day society and discuss the multiple ethical, legal, and social challenges inherent to this technology. Scope of Review. This paper evaluates some of the most visible and challenging topics in the field of ART and outlines the ethical, legal, and social challenges they introduce. Major Conclusions. ART has resulted in a tectonic shift in the way physicians and the general population perceive infertility and ethics. In the coming years, advancing technology is likely to exacerbate ethical, legal, and social concerns associated with ART. ART is directly challenging society to reevaluate the way in which human life, social justice and equality, and claims to genetic offspring are viewed. Furthermore, these issues will force legal systems to modify existing laws to accommodate the unique challenges created by ART. Society has a responsibility to ensure that the advances achieved through ART are implemented in a socially responsible manner.

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
OBJECTIVE To determine whether gonadotropin-releasing hormone (GnRH) analog cotreatment with chemotherapy provides better reproductive outcomes for women at risk of premature ovarian failure (POF) as a side-effect of gonadotoxic chemotherapy. DESIGN Systematic review and meta-analysis. SETTING University-affiliated research centers. PATIENT(S) None. INTERVENTION(S) Electronic and manual searches (e.g., MEDLINE, EMBASE, CENTRAL) up to January 2010 were performed to identify randomized controlled trials (RCTs) comparing GnRH cotreatment with chemotherapy alone in premenopausal women. MAIN OUTCOME MEASURE(S) Incidence of POF after treatment, incidence of women with resumption of ovulation, POF after an initial normal cycle, normal cycles but abnormal markers of ovarian reserve, spontaneous occurrence of pregnancy after treatment, and time to reestablishment of menstruation; data also extracted to allow for an intention-to-treat analysis. RESULT(S) Twenty-eight RCTs were identified, but only six met the inclusion criteria. Data were only available for the incidence of women with new onset of POF, resumption of ovulation, and occurrence of pregnancy. The incidence of POF or resumption of ovulation both demonstrated a statistically significant difference in favor of the GnRH cotreatment. The occurrence of spontaneous pregnancy showed no statistically significant difference between GnRH cotreatment and the control groups. CONCLUSION(S) Evidence from RCTs suggests a potential benefit of GnRH cotreatment with chemotherapy in premenopausal women, with higher rates of spontaneous resumption of menses and ovulation but not improvement in pregnancy rates. Data relating to study quality and possible bias for the majority of the outcomes in this review were not available, denoting possible selective reporting of trial data.

Abstract
PURPOSE To determine whether Activin A affects the activation and survival of human primordial follicles in vitro. METHODS Ovarian cortical biopsies from eight women undergoing elective caesarean sections or benign gynaecological procedures were taken and cut into small pieces (1-3 mm(3)), cultured in serum-free medium for 7 days with/without human recombinant Activin A at a concentration of either 50 or 100 ng/ml. Ovarian tissue were analysed by histology for follicle viability, development and density. RESULT(S) Significant activation of primordial follicles within cultured cortical tissue was observed after 7 days in control medium. However, medium supplemented with Activin A at 50 ng/ml resulted in significant inhibition of follicular activation. Increasing the concentration of Activin A to 100 ng/ml reversed the inhibitory effect. The effect of Activin A appeared to be specific to activation of non-growing (primordial) follicles into the growing population since no significant differences in follicle viability was observed between treatment groups. CONCLUSION(S) Activin A at a concentration of 50 ng/ml can inhibit the spontaneous activation of human primordial follicles in vitro indicating that this may be a component of the signalling mechanisms that maintain follicular quiescence.

Abstract
Transplantation of cryopreserved tissue from patients with cancer may carry the risk of reactivation or redissemination of micrometastases. This prospective study was conducted to evaluate the potential involvement of micrometastases in ovarian tissue in cancer patients. Ovarian biopsies were collected from patients who underwent ovarian tissue cryopreservation, in our IVF unit before chemotherapy between 2000 and 2008. Indications for cryopreservation included breast cancer (n=13), osteosarcoma (n=13), hematologic malignancies (n=13), uterine cervix carcinoma (n=2), endometrial carcinoma (n=1), colon cancer (n=1), and brain medulloblastoma (n=1). The samples were stained with hematoxylin and eosin, and examined histologically. Immunoperoxidase broad-spectrum cytokeratin staining was also performed on specimens from breast cancer patients. There were 44 patients (age range 5-40 yr) who yielded 40 specimens. No gross pathologic involvement was observed, and the histologic examination revealed normal histology with no evidence of metastases. Our findings showed that for the purpose of considering ovarian tissue cryopreservation in cancer patients, the likelihood of microscopic metastases within ovaries of normal appearance is apparently very low. Clarification of the actual risk of ovarian involvement and any subsequent risk of micrometastases and tumor reimplantation requires further investigation.

A simple and efficient method for preparation of isolated ovarian follicles for transmission electron microscopy. J Assist Reprod Genet 2010; 27:97-101. [PMID: 20140639 DOI: 10.1007/s10815-010-9389-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2009] [Accepted: 01/11/2010] [Indexed: 10/19/2022] Open
Abstract
OBJECTIVE A simple method for preparation of isolated ovarian follicles for transmission electron microscopy (TEM) using transwell inserts is described. MATERIALS AND METHODS Pre-antral follicles were enzymatically isolated from mouse ovaries and cultured overnight on transwell insert polyester membranes. The following day, isolated ovarian follicles were processed for TEM by moving the transwell insert through successive wells containing the fixation and embedding reagents. After polymerization of the resin, the polyester membrane with the follicles embedded in the resin was disengaged from the transwell unit. The resin was sectioned. Semi-thin sections were stained with toluidine blue while ultra-thin sections were stained by uranyl acetate and examined by light microscopy and TEM, respectively. RESULTS Isolated ovarian follicles were easily processed in groups for TEM. Follicles were well embedded and there appeared to be no loss of tissue during processing. The ultra-structure of processed isolated ovarian follicles was well preserved with little evidence of processing artifacts. CONCLUSIONS In situ processing and preparation of isolated ovarian follicles by first allowing attachment on transwell insert membranes was shown to be a simple, rapid and effective method for TEM.

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.

[PMID: 19406395 DOI: 10.1016/j.fertnstert.2009.03.028] [Citation(s) in RCA: 89] [Impact Index Per Article: 5.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2008] [Revised: 03/02/2009] [Accepted: 03/04/2009] [Indexed: 11/19/2022]
Abstract
OBJECTIVE To characterize the early experience of a clinical program designed to provide strategies for fertility preservation to female cancer patients about to undergo chemotherapy or radiation therapy. DESIGN Retrospective chart review; case-control study. SETTING Academic medical center. PATIENT(S) Sixty-five female cancer patients and 57 age-matched infertility patients. INTERVENTION Enrollment in a program for fertility preservation. MAIN OUTCOME MEASURE(S) Choice of active participation, fertility preservation option selection, clinical outcomes of patients undergoing oocyte retrieval, attitudes regarding embryo disposition. RESULT(S) Of 65 patients referred to the program, 18 declined to undergo embryo, oocyte, or tissue cryopreservation. Six were found not to be eligible for medical reasons. Of the remaining 41 patients, 35 chose to cryopreserve embryos, four chose to cryopreserve oocytes, and two chose to undergo ovarian tissue freezing. Fewer oocytes were recovered from the embryo cryopreservation group when compared with an age-matched control group, but the mean number of zygotes generated was similar. Attitudes regarding embryo disposition were different between the two groups. No serious clinical sequelae resulted from participation. CONCLUSION(S) Fertility preservation techniques employing available technology may provide safe and practical options to female cancer patients facing chemotherapy or radiation therapy. A significant number of otherwise appropriate participants decline active management. Cancer patients display different attitudes regarding embryo disposition when compared with infertility patients without cancer.

Abstract
Survival for cancer has improved significantly in the last 25 years with excellent overall 5- and 10-year survival rates. Hence, the majority of young women diagnosed with cancer can expect to live for decades, making quality of life issues such as fertility increasingly important. Risks of infertility vary based on the chemotherapy and treatments employed, as well as a woman's age. In general, younger women are less likely to experience permanent amenorrhea than older women, but even women who continue to menstruate have a greatly increased risk of premature menopause. Options for patients with cancer entering chemotherapy treatment, who wish to preserve fertility range from clinically well-established techniques such as embryo cryopreservation to more experimental techniques such as ovarian tissue cryopreservation. Pregnancy does not appear to increase the risk of cancer recurrence. Discussions of fertility issues in premenopausal women diagnosed with cancer present important challenges to the provider and to the patient. However, failure to discuss these options adequately can have lasting negative consequences on a woman's quality of life. Physician education interventions should seek to improve the knowledge of fertility preservations options, and of locally and nationally available resources.
