Abstract
Objective: This paper serves as an up-to-date narrative review of the most effective methods and outcomes of ovarian tissue cryopreservation (OTC) with new data comparing this method to oocyte and embryo cryopreservation as well as its utility in restoration of endocrine function. Background: Data on OTC are becoming more available as more patients are achieving cancer remission and choosing to use their cryopreserved tissue to conceive or restore endocrine function. With OTC only recently becoming a non-experimental method of fertility preservation, it is important to evaluate, compare, and optimize current practices to improve live birth outcomes. Methods: A literature search of meta-analyses, systematic reviews, case series, retrospective studies, and randomized control trials was performed using the PubMed database with multiple search terms. Discussion: Current practices and outcomes of OTC remain heterogeneous, though they are becoming more streamlined with the emerging data on successful live births. Multiple aspects of OTC have been studied to optimize protocols, particularly methods of cryopreserving, in vitro maturation, and transplantation. In vitro follicle maturation is a novel application with emerging data on methods and outcomes. OTC is a versatile method not only for fertility preservation but also for hormone restoration as well. With wider usage of OTC, ethical dilemmas will need to be addressed. Conclusions: OTC can be used as fertility preservation for a variety of patients. Recent studies suggest it may be comparable to embryo cryopreservation, but with growing data on live births, comparative studies should continue to be performed. In vitro follicle maturation (IVFM) is a promising application of ovarian tissue harvesting. Data are lacking on cost-effectiveness, patient satisfaction, and morbidity associated with OTC.

Abstract
RESEARCH QUESTION What impact does the cryopreservation of endometrial tissue have on cell characteristics and molecular and epigenetic profile changes in endometrial tissue and stromal cells? DESIGN Cellular properties, such as proliferation efficiency, surface marker expression and the differentiation potency of endometrial stromal cells (ESC) isolated from fresh (Native) and cryopreserved (Cryo) tissue were compared. Moreover, changes in the expression of genes associated with pluripotency, endometrial function and epigenetic regulation and microRNA (miRNA, miR) were assessed, as were levels of DNA methylation and histone modifications. RESULTS Native and Cryo cells exhibit very similar profiles including cell surface marker expression, differentiation potency and histone modifications, except for a decrease in proliferative potency and cell surface marker SUSD2 expression in Cryo cells. It was demonstrated that endometrial tissue cryopreservation led to an up-regulated expression of genes associated with pluripotency (NANOG, OCT4 [also known as POU5F1]). This confirms that despite being recovered from cryopreserved differentiated tissue, cells retained their stemness properties. In addition, alterations in DNA methyltransferase (DNMT1, DNMT3A, DNMT3B) gene regulation were observed, along with a down-regulation of hsa-miR145-5p in Cryo ESC. CONCLUSIONS These findings contribute to a deeper understanding of the complex effects of endometrial tissue cryopreservation, providing insights for both medical and basic research applications. Since different tissues possess unique characteristics, it is essential to select the most suitable cryopreservation method for each tissue individually. Furthermore, the study findings indicate the potential utility of slow-cooling cryopreservation for both normal and pathological endometrial tissue samples, with the purpose of isolating stromal cell cultures.

Abstract
In recent years, advancements in cryopreservation techniques for oocytes, embryos, and ovarian tissue have enabled offering fertility preservation (FP) options to women with endometriosis. It is recommended to always conduct specialized counselling on FP, especially before considering surgical interventions for endometriosis. The decision regarding the methods of FP, the timing, and to which women affected by endometriosis these techniques should be offered are still subjects of discussion. However, several studies suggest that it can be proposed before surgical interventions for endometriosis, particularly if the patient is undergoing mono or bilateral endometrioma surgery. The most recommended technique is ovarian stimulation, followed by oocyte cryopreservation. Nevertheless, the literature contains various studies describing FP through embryo cryopreservation or the retrieval and cryopreservation of ovarian tissue.

Abstract
There is a global trend of declining fertility among people of childbearing age and mankind is confronted with great challenges of fertility problems. As a result, fertility preservation technology has emerged. Fertility preservation involves interventions and procedures aimed at preserving the patients' chances of having children when their fertility may have been impaired by their medical conditions or the treatments thereof, for example, chemotherapy and/or radiotherapy for cancer. The changes in patients' fertility can be temporary or permanent damage. Fertility preservation can help people diagnosed with cancer or other non-malignant diseases. More and more fertility preservation methods are being used to preserve the fertility of cancer patients and protect their reproductive organs from gonadotoxicity. Fertility preservation may be appropriate for young patients with early-stage cancers and good prognosis before they undergo treatments (chemotherapy and/or radiotherapy) that can negatively affect their fertility. It is also appropriate for patients with chronic conditions or those who have encountered environmental exposures that affect their gonadal function. Fertility preservation methods include oocyte cryopreservation, embryo cryopreservation, and ovarian tissue cryopreservation (OTC) for women and sperm freezing and testicular tissue freezing for men. The survival rates of children and adolescents diagnosed with malignant tumors have been steadily increasing as a result of advances in cancer treatments. Cryopreservation of oocytes and sperm is recognized as a well-established and successful strategy for fertility preservation in pubertal patients. OTC is the sole option for prepubertal girls. On the other hand, cryopreservation of immature testicular tissue remains the only alternative for prepubertal boys, but the technology is still in the experimental stage. A review showed that the utilization rate of cryopreserved semen ranged from 2.6% to 21.5%. In the case of cryopreserved female reproductive materials, the utilization rate ranged from 3.1% to 8.7% for oocytes, approximately from 9% to 22.4% for embryos, and from 6.9% to 30.3% for ovarian tissue. When patients have needs for fertility treatment, cryopreserved vitrified oocytes are resuscitated and in vitro fertilization-embryo transfer (IVF-ET) was performed to help patients accomplish their reproductive objectives, with the live birth rate (LBR) being 32%. On the other hand, when cryopreserved embryos are resuscitated and transferred, the LBR was 41%. OTC has the advantage of restoring natural fertility and presents a LBR of 33%, compared with the LBR of 19% among 266 IVF patients. In addition, OTC has the benefit of restoring the endocrine function. It has been observed that the shortest recovery time of the first menstruation after transplantation was 3.9 months, and the recovery rate of ovarian function reached 100%. To date, a growing number of cancer survivors and patients with other diseases are benefiting from fertility preservation measures. In the face of declining human fertility, fertility preservation provides a new approach to human reproduction. Fertility preservation should be applied in line with the ethical principles so as to fully protect the rights and interests of patients and their offsprings.

Abstract
The importance of ovarian cortical cryopreservation in fertility preservation is receiving increasing attention from reproductive specialists, and mitochondrial dysfunction is an important cause of reduced ovarian tissue cryopreservation. Elamipretide (SS-31) is a novel mitochondria-targeted antioxidant. However, whether it has a protective effect on mouse ovarian tissue cryopreservation remains to be studied. In this study, we examined follicular morphology and viability, mitochondrial function and oxidative stress levels, apoptosis, and culture in vitro after vitrification cryoresuscitation operation by treating ovarian tissues with SS-31 in cryoprotectant resuscitation solution. At the end of the experiment, the addition of 100 μmol/L SS-31 significantly improved follicle quality and oocyte maturation rate in vitro (p < 0.05) and significantly reduced apoptosis (p < 0.05) and oxidative stress levels (superoxide dismutase, catalase, malondialdehyde, p < 0.05). Meanwhile, mitochondrial respiratory chain complex enzyme activity, mtDNA copy number (p < 0.05), and adenosine triphosphate (p < 0.05) content were significantly increased in the 100 μmol/L SS-31-treated group. In addition, the mRNA expression levels of mitochondrial energy metabolism- and biosynthesis-related genes (STRT1, PGC-1a, PPAR-a, TFAM, p < 0.05) were markedly upregulated (p < 0.05) in the 100 μmol/L SS-31 group. In conclusion, SS-31 improved the cryopreservation of ovarian tissues, and 100 μmol/L SS-31 was found to be the most effective.

Abstract
Introduction Long survivors after childhood cancer are increasing thanks to oncological improvements. Their quality of life and fertility-sparing should be considered in the early phases of each oncological pathway. Cryopreservation of ovarian tissue removed before starting gonadotoxic therapies is the only fertility sparing procedure available for prepubertal children affected by cancer and it does not affect the timing of the start of the treatment. Materials and methods The present study shows the surgical and clinical outcomes following laparoscopic ovarian tissue collection (LOTC) for a total of 311 patients aged between 0 and 17 years old from four different European Centers. Results Only two major complications were reported according to the Clavien Dindo classification (0.6%). Discussion LOTC can be considered a safe procedure.

Abstract
Oncology treatments cause infertility, and ovarian tissue cryopreservation and transplantation (OTCT) is the only option for fertility preservation in prepubertal girls with cancer. However, OTCT is associated with massive follicle loss. Here, we aimed to determine the effect of supplementation of slow freezing and vitrification media with BAPTA-AM and melatonin alone and in combination on ovarian tissue viability, reactive oxygen species (ROS) levels, total antioxidant capacity (TAC), and follicular morphology and viability. Our results indicated that BAPTA-AM and melatonin can significantly improve ovarian tissue viability and the TAC/ROS ratio and reduce ROS generation in frozen-thawed ovarian tissues in slow freezing and vitrification procedures. BAPTA-AM was also found to be less effective on TAC compared to melatonin in vitrified ovarian tissue. While supplementation of slow freezing and vitrification media with BAPTA-AM and/or melatonin could increase the percentage of morphologically intact follicles in cryopreserved ovarian tissues, the differences were not significant. In conclusion, supplementation of cryopreservation media with BAPTA-AM or melatonin improved the outcome of ovarian tissue cryopreservation in both vitrification and slow freezing methods. Our data provide some insight into the importance of modulating redox balance and intracellular Ca2+ levels during ovarian tissue cryopreservation to optimize the current cryopreservation methods.

Abstract
BACKGROUND The majority of female cancer patients undergoing anticancer treatments are at risk of experiencing 'cancer treatment-related infertility', which can result in permanent damage to their reproductive prospects. Among the fertility preservation methods, ovarian tissue cryopreservation (OTC) has emerged as an alternative for these patients. The Cancer Institute of Bari initiated a research program to assess the feasibility of OTC. This study compares the viability of ovarian cortical fragments cryopreserved using slow freezing (SF) and ultra-rapid freezing (URF) methods. METHODS Ovarian cortex biopsies were obtained from 11 fertile women enrolled in our oncofertility service between June 2022 and January 2023. After tissue collection, a histological assessment was performed before cryopreservation. OTC was carried out using both SF and URF methods. Six months later, thawed samples were evaluated for follicle counts and histological integrity. RESULTS No statistically significant difference was observed in the proportion of intact follicles (means of 31.5% and 73.0% in the SF and URF groups, respectively; p = 0.064). However, there was a significant difference in the number of follicles between the SF group (n = 149) and the URF group (n = 37) (p = 0.046). CONCLUSIONS We assessed the viability of ovarian cortex after freezing and thawing, focusing on the structural integrity of follicles. Our findings suggest that there are no significant differences between the SF and URF methods.

Abstract
Cryopreservation of somatic tissue has been studied as a tool for the knowledge and conservation of endangered species, such as Antillean manatees. The use of vitrification protocols is an important step in the establishment of biological banks. To decrease the damage caused by this technique, a reduction in the concentration of cryoprotectants has been proposed. Therefore, we aimed to evaluate combinations and concentrations of intracellular cryoprotectants for the conservation of somatic tissues derived from Antillean manatees. Dulbecco's modified Eagle's medium, F-12 composed of 10% fetal bovine serum and 0.25 M sucrose, was supplemented with 3.0 M ethylene glycol (EG) plus 3.0 M dimethyl sulfoxide (DMSO), or 1.5 M EG plus 1.5 M DMSO or 3.0 M EG or 3.0 M DMSO, to produce four solutions for solid-surface vitrification. Noncryopreserved tissues were used as the controls. After warming, tissues derived from four Antillean manatees were evaluated for ultrastructure, histology, and in vitro culture. No differences were observed among the cryopreserved and noncryopreserved tissues in terms of ultrastructure. The dermis thickness of the cryopreserved fragments in solutions containing 3.0 M EG plus 3.0 M DMSO, 3.0 M EG, and 3.0 DMSO was similar to that of the control. Moreover, cryopreservation with 3.0 M EG plus 3.0 M DMSO maintained tissue proliferative capacity potential evaluated by quantification of nucleolar organizing regions. Nevertheless, none of the cryopreserved fragments were able to maintain the number of fibroblasts and the collagen percentage as compared with that of the noncryopreserved fragments. Also, none of the cryopreserved fragments in the different solutions were able to produce cells in vitro. In summary, even reducing the concentration of intracellular cryoprotectants as well as their association did not guarantee the maintenance of cells after in vitro culture. Further studies are needed to optimize the cryopreservation protocols in Antillean manatee somatic tissues.

Abstract
The aim of our laboratory-based study was to investigate the extent of delayed-onset cell death after cryopreservation in endothelial and epithelial cell lines of ovarian origin. We found differences in percentages of vital cells directly after warming and after cultivation for 48 to 72 h. A granulosa cell line of endothelial origin (KGN) and an epithelial cell line (OvCar-3) were used. In both DMSO-containing and DMSO-free protocols, significant differences in vitality rates between the different cell lines when using open and closed vitrification could be shown (DMSO-containing: KGN open vs. OvCar open, p = 0.001; KGN closed vs. OvCar closed, p = 0.001; DMSO-free: KGN open vs. OvCar open, p = 0.001; KGN closed vs. OvCar closed, p = 0.031). Furthermore, there was a marked difference in the percentage of vital cells immediately after warming and after cultivation for 48 to 72 h; whereas the KGN cell line showed a loss of cell viability of 41% using a DMSO-containing protocol, the OvCar-3 cell loss was only 11% after cultivation. Using a DMSO-free protocol, the percentages of late-onset cell death were 77% and 48% for KGN and OvCar-3 cells, respectively. Our data support the hypothesis that cryopreservation-induced damage is cell type and cryoprotective agent dependent.

Abstract
As cancer therapies continue to improve, the survival rates of adolescent and young adult patients have increased. Consequently, considering patient quality of life after cancer, including family building, has become an essential aspect of establishing a treatment plan. However, the gonadotoxic nature of many chemotherapeutic agents limits the option of using one's own gamete for family building. In recent years, significant advancements have been made in oncofertility, particularly vitrification of oocytes. Unfortunately, as with many areas of medicine, health disparities limit those that can access and utilize fertility preservation prior to cancer treatment. This review aims to shed light on existing disparities in oncofertility for female patients, to offer recommendations to enhance education, access, and advocacy, as well as identify potential areas for future research.

Abstract
Human oogenesis is a highly complex and not yet fully understood process due to ethical and technological barriers that limit studies in the field. In this context, replicating female gametogenesis in vitro would not only provide a solution for some infertility problems, but also be an excellent study model to better understand the biological mechanisms that determine the formation of the female germline. In this review, we explore the main cellular and molecular aspects involved in human oogenesis and folliculogenesis in vivo, from the specification of primordial germ cells (PGCs) to the formation of the mature oocyte. We also sought to describe the important bidirectional relationship between the germ cell and the follicular somatic cells. Finally, we address the main advances and different methodologies used in the search for obtaining cells of the female germline in vitro.

Abstract
Although much of the foundational basic scientific and clinical research was conducted in the United States, the first in vitro fertilization (IVF) birth occurred in the United Kingdom. Why? For centuries, all research surrounding the field of "reproduction" has elicited bipolar passionate responses by the American public, and the issue of "test tube babies" has been no different. The history of conception in the United States is defined by complex interrelationships among scientists, clinicians, and politically charged decisions by various branches of the US government. With a focus on research in the United States, this review summarizes the early scientific and clinical advances important to the development of IVF and then addresses the potential future developments in IVF. We also consider what future advances are possible in the United States given the current regulations, laws, and funding.

Abstract
Due to the impact of the modern lifestyle, female infertility has been reduced because of different reasons. For example, in combined chemotherapeutic therapies, a small fraction of cancer survivors has faced different post-complications and side effects such as infertility. Besides, in modern society, delayed age of childbearing has also affected fertility. Nowadays, ovarian tissue cryopreservation and transplantation (OTC/T) is considered one of the appropriate strategies for the restoration of ovarian tissue and bioactivity in patients with the loss of reproductive function. In this regard, several procedures have been considered to improve the efficacy and safety of OTT. Among them, a surgical approach is used to transplant ovaries into the optimal sites, but the existence of ischemic changes and lack of appropriate revascularization can lead to bulk follicular atresia. Besides, the role of OTC/T is limited in women of advanced maternal age undergoing lifesaving chemo-radiation. As a correlate, the development of de novo approaches with efficacious regenerative outcomes is highly welcomed. Tissue engineering shows high therapeutic potentialities to restore fertility in males and females using the combination of biomaterials, cells, and growth factors. Unfortunately, most synthetic and natural materials are at the experimental stage and only the efficacy has been properly evaluated in limited cases. Along with these descriptions, strategies associated with the induction of angiogenesis in transplanted ovaries can diminish the injuries associated with ischemic changes. In this review, the authors tried to summarize recent techniques, especially tissue engineering approaches for improving ovarian function and fertility by focusing on angiogenesis and neovascularization.

Abstract
Cancer during childhood and adolescence remains a major public health issue, affecting a significant portion of this age group. Although newer anti-cancer treatments have improved survival rates, this comes at a cost in terms of gonadotoxic effects. As a result, the preservation of fertility is important. Ovarian tissue cryopreservation, one of the newest methods, has some advantages, especially for prepubertal patients: no need for ovarian stimulation, thus, no further risk for estrogen-sensitive cancer types, and preservation of more and better-quality primordial follicles of the ovarian cortex. The most frequent indications include treatment with alkylating agents, ovarian-focused radiotherapy, leukemias, lymphomas, brain and neurological tumors, as well as Turner syndrome and benign hemoglobinopathies. An expected survival exceeding 5 years, the absence of systematic disease and an overall risk of premature ovarian insufficiency over 50% are among the criteria that need to be fulfilled in order for a patient to undertake this method. Orthotopic transplantation is more frequently used, since it can allow both live birth and the recovery of endocrine function. Reimplantation of malignant cells is always a major risk and should always be taken into consideration. Histological analysis, as well as immunohistochemical and molecular methods, are needed in order to improve the search for malignant cells before transplantation. Ovarian tissue cryopreservation appears to be a method with specific benefits, indications and risks which can be an important tool in terms of preserving fertility in younger women.

Abstract
High survival rates in adolescent cancer patients have shifted the medical focus to the long-term outcomes of cancer treatments. Surgery, chemotherapy, and radiation increase the risk of infertility and infertility-related distress in adolescent cancer patients and survivors. The aims of this narrative review were to (1) describe the psychosocial impacts of cancer-related infertility in adolescents, (2) identify multilevel barriers to fertility preservation (FP) conversations and referrals, and (3) conclude with evidence-based clinical solutions for improving the oncofertility support available to Canadian adolescents. The results of this review revealed that FP decisions occur within the patient, parent, and health care provider (HCP) triad, and are influenced by factors such as parent attitudes, patient maturity, and HCP knowledge. Decision tools and HCP education can promote the occurrence of developmentally appropriate fertility discussions. At the systems level, cost and resource barriers prevent patients from receiving sufficient fertility information and referrals. Clinical models of care (MOCs) can define interdisciplinary roles and referral pathways to improve the integration of oncofertility services into adolescent cancer care. The continued integration of oncofertility care will ensure that all Canadian adolescents receive the exemplary medical and psychological support necessary to make empowered decisions about their own fertility.

Abstract
Traditional fertility preservation methods such as embryo or oocyte cryopreservation cannot meet the needs of a cancer patient or for personal reasons. The cryopreservation of ovarian tissue can be an alternative and has become a hot spot to preserve fertility or hormone replacement. The freezing of ovarian tissue can be carried out at any time without ovarian hyperstimulation to retrieve follicles. It is an ideal strategy to preserve reproductive function in children, adolescent cancer patients, and patients who are in urgent need of cancer treatment. With the increasing demands of women with premature ovarian failure or in menopause, ovarian tissue transplantation is also an alternative for hormone replacement that can provide physiological doses of hormone levels, which can avoid a series of risks such as thrombosis, breast cancer, or other hormone-dependent tumors, caused by oral hormone replacement. Hence, ovarian tissue banking can be regarded as a mainstream strategy for fertility preservation and anti-menopause hormone replacement in further clinical investigation.
