Abstract
Cancer is the leading cause of death worldwide. Fortunately, the survival rate of cancer continues to rise, owing to advances in cancer treatments. However, these treatments are gonadotoxic and cause infertility. Ovarian tissue cryopreservation and transplantation (OTCT) is the most flexible option to preserve fertility in women and children with cancer. However, OTCT is associated with significant follicle loss and an accompanying short lifespan of the grafts. There has been a decade of research in cryopreservation-induced oxidative stress in single cells with significant successes in mitigating this major source of loss of viability. However, despite its success elsewhere and beyond a few promising experiments, little attention has been paid to this key aspect of OTCT-induced damage. As more and more clinical practices adopt OTCT for fertility preservation, it is a critical time to review oxidative stress as a cause of damage and to outline potential ameliorative interventions. Here we give an overview of the application of OTCT for female fertility preservation and existing challenges; clarify the potential contribution of oxidative stress in ovarian follicle loss; and highlight potential ability of antioxidant treatments to mitigate the OTCT-induced injuries that might be of interest to cryobiologists and reproductive clinicians.

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.

Improvement of Fertilization Capacity and Developmental Ability of Vitrified Bovine Oocytes by JUNO mRNA Microinjection and Cholesterol-Loaded Methyl-β-Cyclodextrin Treatment. Int J Mol Sci 2022; 24:ijms24010590. [PMID: 36614032 PMCID: PMC9820539 DOI: 10.3390/ijms24010590] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Revised: 12/09/2022] [Accepted: 12/11/2022] [Indexed: 12/31/2022] Open
Abstract
Vitrification of oocytes is crucial for embryo biotechnologies, germplasm cryopreservation of endangered and excellent female animals, and the fertility of humans. However, vitrification significantly impairs the fertilization ability of oocytes, which significantly limits its widely used application. JUNO protein, a receptor for Izumo1, is involved in sperm-oocyte fusion and is an indispensable protein for mammalian fertilization, and its abundance is susceptible to vitrification. However, it is still unclear how vitrification reduces the fertilization capacity of bovine oocytes by affecting JUNO protein. This study was designed to investigate the effect of vitrification on the abundance and post-translational modifications of JUNO protein in bovine oocytes. Our results showed that vitrification did not alter the amino acid sequence of JUNO protein in bovine oocytes. Furthermore, the liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis results showed that vitrification significantly reduced the number and changed the location of disulfide bonds, and increased the number of both phosphorylation and glycosylation sites of JUNO protein in bovine oocytes. Finally, the fertilization capacity and development ability of vitrified oocytes treated with 200 pg JUNO mRNA microinjection and cholesterol-loaded methyl-β-cyclodextrin (CLC/MβCD) were similar to those of fresh oocytes. In conclusion, our results showed that vitrification of bovine oocytes did not alter the protein sequence of JUNO, but induced post-translational modifications and changed protein abundance. Moreover, the fertilization and development ability of vitrified bovine oocytes were improved by the combination treatment of JUNO mRNA microinjection and CLC/MβCD.

Abstract
PURPOSE The aim of the present study was to investigate the effect of glutathione ethyl ester (GSH-OEt) in the recovery medium on the developmental competence of mouse vitrified-warmed MII oocytes. METHODS Vitrified-warmed oocytes were incubated for 1 h in recovery medium in the presence or absence of 0.5 mM GSH-OEt. The authors examined the effects of GSH-OEt, first on the levels of glutathione (GSH) and reactive oxygen species (ROS) in vitrified-warmed oocytes, and second, on in vitro blastocyst development, division speed to blastocysts, and total cell numbers of blastocysts from vitrified-warmed oocytes fertilized by Intracytoplasmic sperm injection (ICSI). RESULTS Adding GSH-OEt to the recovery medium significantly (p < 0.05) increased GSH content and decreased ROS levels in vitrified-warmed oocytes. The blastocyst rate did not differ significantly between the two groups, but the speed of development to blastocysts in the GSH-OEt (+) group was significantly more rapid. In addition, the total blastocyst cell number was significantly higher in the GSH-OEt (+) group than in the GSH-OEt (-) group (92.8 ± 5.1 vs. 71.4 ± 3.5, p < 0.01). CONCLUSION Adding GSH-OEt to the recovery medium of vitrified-warmed mouse oocytes enhances the development potential of oocytes and improves the quality of blastocysts.

Abstract
PURPOSE A retrospective study examining the effects of embryo re-expansion before transfer on pregnancy outcomes for frozen embryo transfers (FET). METHODS A total of 486 FET cycles from November 2017 through December 2019 were studied. These cycles included patients using autologous, donor oocytes, and donor embryo with patients ranging from ages 23 to 48 years with infertility diagnoses. Programmed FET priming was performed with exogenous estrogen and progesterone. All blastocysts were cultured in trigas incubators for 20 min to 4 h and 42 min. Pictures of each blastocyst after thaw and before transfer were taken utilizing the Hamilton Thorne Zilos laser software (Beverly, MA). The longest portion of the embryo was measured in µm. Pregnancy was defined by a positive hCG, and ongoing clinical pregnancy was defined by the presence of fetal cardiac activity. Wilcoxon rank sum tests were used to access differences in change parameters. RESULTS There is no significant difference in the amount of embryo expansion or contraction to achieve an ongoing pregnancy. The difference remained non-significant when stratified by embryo expansion or contraction. The amount of change over time and percent change from the first measurement were also not associated with achieving an ongoing pregnancy. This remained true after adjustment for patient age and whether or not a biopsy was performed. CONCLUSIONS Embryos that do not re-expand after warming appear to have a similar chance of achieving a successful pregnancy as those that do re-expand.

Abstract
The combination of in vitro maturation (IVM) techniques and oocyte vitrification (OV) could increase the number of useful oocytes in different types of patients. IVM and subsequent OV is the most widely used clinical strategy. Would the results improve if we reverse the order of the techniques? Here, we evaluated survival, in vitro maturation, time to extrude the first polar body (PB), and the metaphase plate configuration of human prophase I (GV) oocytes before or after their vitrification. Specific, 195 GV oocytes from 104 patients subjected to controlled ovarian stimulation cycles were included. We stablished three experimental groups: GV oocytes vitrified and IVM (Group GV-Vit), GV oocytes IVM and vitrified at MII stage (Group MII-Vit), and GV oocytes IVM (Group not-Vit). All of them were in vitro matured for a maximum of 48 h and fixed to study the metaphase plate by confocal microscopy. According to our results, the vitrification of immature oocytes and their subsequent maturation presented similar survival, maturation, and metaphase plate conformation rates, but a significantly higher percentage of normal spindle than the standard strategy. Additionally, the extension of IVM time to 48 h did not seem to negatively affect the oocyte metaphase plate configuration.

Abstract
Young women diagnosed with cancer today have a greater chance of long-term survival than ever before. Successful survivorship for this group of patients includes maintaining a high quality of life after a cancer diagnosis and treatment; however, lifesaving treatments such as chemotherapy, radiation, and surgery can impact survivors by impairing reproductive and endocrine health. Expert oncologists along with reproductive medicine specialists discuss fertility preservation options in this chapter since fertility preservation is becoming a priority for young women with breast cancer. This expert group used data from published literature, practical experience and opinion of a large group of academic oncologists to arrive at these practical consensus recommendations for the benefit of community oncologists.

Abstract
Two basic methods for the laboratory-focused cryopreservation of mammalian oocytes are described, based on work with murine oocytes. One method uses a relatively low concentration of the cryoprotectant propanediol plus sucrose and requires controlled rate cooling equipment to achieve a slow cooling rate. This method has also produced live births from cryopreserved human oocytes. The second method, which is described here, employs a high concentration of the cryoprotectant dimethyl sulfoxide plus a low concentration of polyethylene glycol. This is a vitrification method, which involves ultra-rapid cooling by plunging standard straws into liquid nitrogen vapor, hence avoiding the need for specialized equipment, but requires technical ability to manipulate the oocytes quickly in the highly concentrated cryoprotectant solutions. Murine oocytes that have been vitrified using this technique have resulted in live births. Vitrification using other cryoprotectant mixtures is now a popular clinically accepted method for cryobanking of human oocytes.

Abstract
Various types of cells are routinely cryopreserved in modern regenerative and cell-based medicines. For instance, the oocyte is one of the most demanding cells to be cryopreserved in genetic engineering and human-assisted reproductive technology (ART). However, the usage of cryopreserved oocytes in ART clinics is still limited mainly because of the unstable survival rate. This is due to the fact that oocytes are more prone to be damaged by ice crystals in comparison to other cells, as oocytes are larger in size and surface area. Meanwhile, oocytes contain more water, and thus, ice crystals are easier to form inside the cells. Currently, to avoid injury by the formed ice crystals, cryopreservation (CP) of oocytes has to use large amounts of small molecules as cryoprotectants such as dimethyl sulfoxide (DMSO) and ethylene glycol (EG), which can permeate into the cell and prevent ice formation inside. However, these molecules are chemically and epigenetically toxic to cells. Therefore, great efforts have been focused on reducing the amount of DMSO and EG used for oocyte CP. In nature, the antifreeze (glyco)proteins (AFGPs) locate extracellularly with the ability to protect living organisms from freezing damage via controlling ice growth. Inspired by this, biocompatible and nontoxic L-proline oligomers (L-Pron), which have the same polyproline II helix structure as that of AFGPs, are first employed for the CP of oocytes. The experimental results reveal that L-Pro8 has a profound activity in inhibiting ice growth as that of AFGP8. Also, by the addition of 50 mM L-Pro8, the amount of DMSO and EG can be greatly reduced by ca. 1.8 M for oocyte CP; moreover, the survival rate of the cryopreserved oocytes is increased up to 99.11%, and the coefficient of variance of the survival rate is decreased from 7.47 to 2.15%. These results mean that almost all oocytes can survive after CP with our method; importantly, the mitochondrial function as a critical criterion for the quality of the frozen-thawed oocytes is also improved. It is proposed that with the addition of L-Pro8, the extracellular ice growth is slowed down, which prevents the direct injuries of cells by large ice crystals and the accompanying osmotic pressure increase. As such, this work is not only significant for meeting the ever-increasing demand by the ART clinics but also gives guidance for designing materials in controlling ice growth during CP of other cells and tissues.

Abstract
Oocyte cryopreservation is an important technology in assisted reproduction and fertility preservation. However, the developmental potential of cryopreserved oocyte remains poor. Osmotic stress injury (OSI) during cryoprotectants (CPAs) loading and unloading steps has critical impact on successful cryopreservation. In order to minimize OSI to oocytes, a microfluidic device was designed and fabricated to achieve continuous CPA concentration change. MII porcine oocytes were loaded and unloaded CPAs with step-wise and microfluidic methods, oocyte volume changes were recorded and compared, loading and unloading duration of microfluidic methods were optimized. The survival and developmental rate of treated oocytes in step-wise and microfluidic linear methods were also evaluated. The results showed that oocyte volume changes with microfluidic method were obviously less than step-wise method, and the survival, cleavage and blastocyst rate of oocytes were 95.3%, 64.4%, and 19.4%, respectively, which were significantly higher than the traditional step-wise method (79.4%, 43.6%, and 9.7%) (p < 0.05). In conclusion, microfluidic device can effectively reduce the osmotic damage to oocytes and improve the survival rate and developmental rate of oocytes, which may provide a new path for oocyte cryopreservation.

Abstract
In vitro fertilization (IVF) has been one of the most exciting modern medical technologies. It has transformed the landscape of human infertility treatment. However, current IVF procedures still provide limited accessibility and affordability to most infertile couples because of the multiple cumbersome processes and heavy dependence on technically skilled personnel. Microfluidics technology offers unique opportunities to automate IVF procedures, reduce stress imposed upon gametes and embryos, and minimize the operator-to-operator variability. This article describes the rapidly evolving state of the application of microfluidics technology in the field of IVF, summarizes the diverse angles of how microfluidics has been complementing or transforming current IVF protocols, and discusses the challenges that motivate continued innovation in this field.

Abstract
SummaryMouse and lamb oocytes were vitrified with, or exposed to, different cryoprotectants and evaluated for their effects on their survival and developmental competence after in vitro fertilization (IVF) and activation treatments. Control oocytes remained untreated, whilst the remainder were exposed to three different combinations of vitrification solutions [dimethyl sulfoxide (DMSO) + ethylene glycol (EG), EG only, or propanediol (PROH) + EG] and either vitrified or left unfrozen (exposed groups). Oocytes in the control and vitrified groups underwent IVF and developmental competence was assessed to the blastocyst stage. In lambs, survival rate in vitrified oocytes was significantly lower than for oocytes in the exposed groups (P <0.05). Blastocyst development was low in vitrified oocytes compared with controls (<6% vs 38.9%, P <0.01). Parthenogenetic activation was more prevalent in vitrified lamb oocytes compared with controls (P <0.05). No evidence of zona pellucida hardening or cortical granule exocytosis could account for reduced fertilization rates in vitrified lamb oocytes. Mouse oocytes demonstrated a completely different response to lamb oocytes, with survival and parthenogenetic activation rates unaffected by the vitrification process. Treatment of mouse oocytes with DMSO + EG yielded significantly higher survival and cleavage rates than treatment with PROH + EG (87.8% and 51.7% vs 32.7% and 16.7% respectively, P <0.01), however cleavage rate for vitrified oocytes remained lower than for the controls (51.7% vs 91.7%, P <0.01) as did mean blastocyst cell number (33 ± 3.1 vs 42 ± 1.5, P <0.05). From this study, it is clear that lamb and mouse show different tolerances to cryoprotectants commonly used in vitrification procedures, and careful selection and testing of species-compatible cryoprotectants is required when vitrifying oocytes to optimize survival and embryo development.

Abstract
Aim In recent years, the importance of fertility preservation (FP) has increased. In vitro maturation (IVM), an important technique in FP, has started to be used in the clinic, but controversies persist regarding this technique. Here, a survey of IVM for FP is provided. Methods Based on a literature review, the applications of FP, methods of FP, IVM of oocytes that had been collected in vivo and ex vivo, maturation of oocytes after IVM for FP, cryopreservation of oocytes for FP, explanation of the procedures to patients, and recent research on FP using IVM were investigated. Results Although IVM for FP remains controversial, the application of FP is expected to expand. Depending on the age and disease status of the patient, various methods of oocyte collection and ovarian stimulation, as well as various needle types and aspiration pressures, have been reported. The maturation rate of IVM in FP ranges widely and requires optimization in the future. In regard to cryopreservation for matured oocytes, the vitrification method is currently recommended. Conclusion Regarding FP for patients with cancer, the treatment of cancer is prioritized; thus, the time and use of medicines are often constrained. As several key points regarding IVM remain unclear, well‐designed and specific counseling for patients is necessary.

Raman-microscopy investigation of vitrification-induced structural damages in mature bovine oocytes. PLoS One 2017; 12:e0177677.

Abstract
Although oocyte cryopreservation has great potentials in the field of reproductive technologies, it still is an open challenge in the majority of domestic animals and little is known on the biochemical transformation induced by this process in the different cellular compartments. Raman micro-spectroscopy allows the non-invasive evaluation of the molecular composition of cells, based on the inelastic scattering of laser photons by vibrating molecules. The aim of this work was to assess the biochemical modifications of both the zona pellucida and cytoplasm of vitrified/warmed in vitro matured bovine oocytes at different post-warming times. By taking advantage of Principal Component Analysis, we were able to shed light on the biochemical transformation induced by the cryogenic treatment, also pointing out the specific role of cryoprotective agents (CPs). Our results suggest that vitrification induces a transformation of the protein secondary structure from the α-helices to the β-sheet form, while lipids tend to assume a more packed configuration in the zona pellucida. Both modifications result in a mechanical hardening of this cellular compartment, which could account for the reduced fertility rates of vitrified oocytes. Furthermore, biochemical modifications were observed at the cytoplasmic level in the protein secondary structure, with α-helices loss, suggesting cold protein denaturation. In addition, a decrease of lipid unsaturation was found in vitrified oocytes, suggesting oxidative damages. Interestingly, most modifications were not observed in oocytes exposed to CPs, suggesting that they do not severely affect the biochemical architecture of the oocyte. Nevertheless, in oocytes exposed to CPs decreased developmental competence and increased reactive oxygen species production were observed compared to the control. A more severe reduction of cleavage and blastocyst rates after in vitro fertilization was obtained from vitrified oocytes. Our experimental outcomes also suggest a certain degree of reversibility of the induced transformations, which renders vitrified oocytes more similar to untreated cells after 2 h warming.

Abstract
The purpose of our study was to assess the effect of vitrification with or without the presence of calcium in the vitrification solution on the: 1) diameter of oocytes and thickness of the zona pellucida, 2) zona pellucida hardening, 3) expression of mRNA follistatin (FST) and cathepsin B (CTSB) in oocytes and 4) developmental competence of embryos derived from in vitro matured and vitrified oocytes. The results of our study demonstrate, that vitrification did not alter thickness of the zona pellucida and diameter of the oocytes, however it triggered hardening of the zona pellucida. The presence of calcium in the vitrification solutions intensified hardening of zona in immature and mature oocytes (P < 0.04, P < 0.001, respectively) and provoked increased mRNA FST expression in oocytes matured in vitro compared to immature oocytes (P < 0.01) and those vitrified without calcium (P < 0.004). CTSB mRNA expression was increased in immature oocytes and oocytes vitrified with calcium compare to mature oocytes (P < 0.02). The developmental potential of vitrified oocytes was impaired compared to non-vitrified oocytes, being more evident in oocytes vitrified with calcium. In summary, vitrification did not change the oocyte diameter and thickness of the zona pellucida and expression of FST and CTSB mRNA. It diminished developmental potential of the vitrified oocytes. The presence of calcium in the vitrification solutions increased hardening of zona pellucida as well as affected the level of FST and CTSB mRNA in oocytes and developmental potential of these oocytes.

Abstract
Current freezing technology, especially the vitrification method, has markedly improved oocyte survival rate after warming, and the pregnancy rate is comparable to that achieved with fresh oocytes. However, most groups report using oocytes matured in vivo for vitrification. Although immature oocytes can be vitrified successfully, clinical outcomes do not reach that of vitrification of matured oocytes. The current literature suggests that oocytes should be vitrified at mature metaphase II (M-II) stage following IVM rather than at the immature germinal vesicle (GV) stage, because the potential for oocyte maturation is reduced when vitrification is performed on immature oocytes at the GV stage.

Abstract
From December 2000 until 2010, the researchers at Royan Institute conducted a wide range
of investigations on ovarian tissue cryopreservation with the intent to provide fertility pres-
ervation to cancer patients that were considered to be candidates for these services. In 2010,
Royan Institute established the Royan Human Ovarian Tissue Bank as a subgroup of the
Embryology Department. Since its inception, approximately 180 patients between the ages
of 747 years have undergone consultations. Ovarian samples were cryopreserved from 47
patients (age: 7-35 years) diagnosed with cervical adenocarcinoma (n=9); breast carcinoma
(n=7), Ewing’s sarcoma (n=7), opposite side ovarian tumor (n=7), endometrial adenocarci-
noma (n=4), malignant colon tumors (n=3), as well as Hodgkin’s lymphoma, major thalas-
semia and acute lymphoblastic leukemia (n=1-2 patients for each disease). Additionally,
two patients requested ovarian tissue transplantation after completion of their treatments.

Abstract
Preservation of fertility is an important issue in the management of young cancer patients. Though embryo cryostorage is a well-established procedure, it can only be availed by couples. Recent studies have indicated increasing success rates with mature and immature oocyte cryopreservation. Cryostorage induces injuries on the human oocytes which can be minimized by slow freezing and vitrification. Selection of candiidates is crucial so that the most suitable technique can be offered without any delay in initiation of cancer therapy. Factors affecting suitability are age of patient, assessment of ovarian reserve, hormonal status and type and stage of neoplastic disease. Encouraging results have been obtained with oocyte in vitro maturation (IVM) followed by vitrification for cryostorage. Data on the use of vitrified eggs in routine in vitro fertilization (IVF) show that pregnancy rates can be comparable to those achieved with fresh oocytes.

Abstract
Both sperm and embryo cryopreservation have become routine procedures in human assisted reproduction and oocyte cryopreservation is being introduced into clinical practice and is getting more and more widely used. Embryo cryopreservation has decreased the number of fresh embryo transfers and maximized the effectiveness of the IVF cycle. The data shows that women who had transfers of fresh and frozen embryos obtained 8% additional births by using their cryopreserved embryos. Oocyte cryopreservation offers more advantages compared to embryo freezing, such as fertility preservation in women at risk of losing fertility due to oncological treatment or chronic disease, egg donation, and postponing childbirth, and eliminates religious and/or other ethical, legal, and moral concerns of embryo freezing. In this review, the basic principles, methodology, and practical experiences as well as safety and other aspects concerning slow cooling and ultrarapid cooling (vitrification) of human embryos and oocytes are summarized.

Abstract
Cancer therapies are known to alter the reproductive potential in cancer patients. Due to improved survival rates in cancer patients of reproductive age, considerations of the long-term effects of cancer therapy have become more significant. Oncofertility is a new discipline in medicine that deals with maintaining the reproductive potential of cancer patients while they are receiving gonadotoxic cancer treatment. The purpose of this review is to explore how cancer treatment impairs reproductive functioning and present the current options for preservation of fertility in women. All patients with reproductive potential should be made aware of the possible treatment-related infertility and be offered appropriate fertility preservation options before cancer treatment is instituted. The hope is that, in the future, mechanism(s) can be developed to preserve immature germ cells in the ovary, so that they can be used for fertilization in vivo or in vitro.

Abstract
Recent technological advances provide new tools to manipulate cells and biological agents in micro/nano-liter volumes. With precise control over small volumes, the cell microenvironment and other biological agents can be bioengineered; interactions between cells and external stimuli can be monitored; and the fundamental mechanisms such as cancer metastasis and stem cell differentiation can be elucidated. Technological advances based on the principles of electrical, magnetic, chemical, optical, acoustic, and mechanical forces lead to novel applications in point-of-care diagnostics, regenerative medicine, in vitro drug testing, cryopreservation, and cell isolation/purification. In this review, we first focus on the underlying mechanisms of emerging examples for cell manipulation in small volumes targeting applications such as tissue engineering. Then, we illustrate how these mechanisms impact the aforementioned biomedical applications, discuss the associated challenges, and provide perspectives for further development.

METHODS For vitrification, oocytes were (1) immediately placed in equilibration solution or (2) they were gradually exposed to the cryoprotectants. For warming, oocytes were placed (1) in a 25 μl preheated (37 °C) thawing solution droplet that was put at room temperature for 1 min once the oocytes were inside or (2) in a 150 μl droplet for 1 minute at 37 °C. RESULTS Survival and preimplantation development were significantly lower when warming was performed in a small preheated droplet. There was no significant difference in survival and embryo development between the gradual or direct exposure to cryoprotectants. CONCLUSIONS Using this high security closed vitrification device a 90 % survival rate can be achieved when the oocytes are immediately warmed in a large volume at 37 °C.

Abstract
Thanks to the progress in oncostatic treatments, young women affected by cancer have a
fairly good chance of surviving the disease and leading a normal post-cancer life. Quite
often, however, polychemiotherapy and/or radiotherapy can induce ovarian damage and
significantly reduce the content of follicles and oocytes inside the ovary, thus predisposing
the patient to menstrual disorders, infertility, and precocious menopause. Several
techniques have been proposed to preserve fertility in these patients; among them oocyte
collection and cryopreservation prior to the oncostatic treatment has been widely applied
in the last decade. The proper indications, the permitting conditions, the available
hormonal stimulation protocols, as well as the effectiveness and limits of this option will be
discussed herein, with a comprehensive and up-to-date review of the two techniques
commonly used to cryostore oocytes, the slow-freezing technique and the vitrification technique.

Abstract
With the evolution of the treatment of malignant neoplasms, the survival rates of patients undergoing chemo- or radiotherapy are increasing. The continuous development of techniques of assisted human reproduction has led to important strategies in an attempt to maintain reproductive function in patients subjected to treatment of neoplastic diseases, among them cryopreservation of embryos, gametes, and ovarian cortical tissue. The freezing of ovarian tissue is currently being proposed with the primary purpose of preserving ovarian function in these patients. Currently, the major challenge of groups working with preservation of fertility is the use of cryopreserved ovarian tissue after disease remission. The main alternatives presented today are the implantation of hetero- or orthotopic tissue and isolation of immature follicles from ovarian tissue followed by in vitro maturation and assisted reproduction procedures.

Abstract
PURPOSE The cryopreservation of immature oocytes permits oocyte banking for patients at risk of losing their fertility. However, the optimum protocol for such fertility preservation remains uncertain. METHODS The present study investigated the survival, maturation, cytoskeletal and chromosome organization of sibling immature oocytes leftover from controlled ovarian stimulation cycles, that were either slow-frozen (with choline-substitution) or vitrified. A comparison group included oocytes that were never cryopreserved. RESULTS Among the three groups, comparable rates were observed for both survival (67-70%) and polar body extrusion (59-79%). Significantly more oocytes underwent spontaneous activation after IVM following slow-freezing compared with either vitrification or no cryopreservation. Likewise, the incidence of spindle abnormalities was greatest in the slow-frozen group, with no differences in spindle morphometrics or chromosome organization. CONCLUSIONS While the overall incidence of mature oocytes with normal bipolar spindles from warmed immature oocytes was low, the yield using Cryoleaf vitrification was slightly superior to choline-based slow-freezing.

Abstract
This study was designed to examine the recovery of mitochondrial function and endogenous antioxidant systems in vitrified oocytes during extended incubations. After 16 hr of in vitro maturation, bovine meiosis-II oocytes were vitrified, and then surviving oocytes were cultured an additional 8 hr. ATP content, ATP synthase activity, expression of ATP synthase F0 subunit 6 (ATP6) and 8 (ATP8) genes, and reactive oxygen species (ROS) levels were investigated in the vitrified oocytes during this additional period (4 or 8 hr). The results showed that: (1) the ATP content and ATP synthase activities in vitrified oocytes at 8 hr post-warming (754.6 fmol, 25.9 nmol NADH/min/mg) were significantly higher than in oocytes immediately warmed (568.3 fmol, 8.7 nmol NADH/min/mg), but still lower than in control oocytes (901.5 fmol, 30.7 nmol NADH/min/mg); (2) the relative expression of ATP6 and ATP8 was initially down-regulated in oocytes when they were first warmed, increased by 4 hr post-warming, and were again down-regulated by 8 hr post-warming; (3) ROS levels in oocytes at 0, 4, and 8 hr post-warming were significantly higher than in control oocytes; and (4) after parthenogenetic activation, the blastocyst rate of oocytes at 8 hr post-warming (26.7%) was significantly higher than that of oocytes immediately warmed (16.9%). These results indicated that mitochondrial function and endogenous antioxidant systems recovered significantly better in vitrified-thawed bovine oocytes with 8 hr of additional incubation, but they did not achieve the activity levels found in fresh oocytes.

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
The objective of this study was to determine the efficacy of vitrification of human oocytes before and after in-vitro maturation (IVM). The immature oocytes recovered (n = 472) were divided into two groups: (i) immature oocytes (n = 219) vitrified at the germinal vesicle (GV) stage; and (ii) immature GV-stage oocytes (n = 253) that were firstly matured in vitro (MII-stage oocytes; n = 178), then vitrified (n = 79). The remaining oocytes (n = 99), which were not vitrified, were processed as controls. After warming, the oocyte survival, maturation and fertilization rates, as well as embryonic development, were compared. The results showed no significant difference between the survival rates of the oocytes vitrified at GV stage and those vitrified at MII stage (85.4% versus 86.1%). However, oocyte maturation rates were significantly reduced (P < 0.05) when oocytes were vitrified at immature GV stage followed by IVM (50.8%) in comparison with the control group (70.4%). Following insemination by intracytoplasmic sperm injection, there was no difference in the fertilization (62.1% versus 58.8%), cleavage (69.5% versus 67.5%) and blastocyst development (0.0% versus 0.0%) rates between these two groups. However, these results were significantly lower (P < 0.05) than those achieved in the control group. This suggests that better results can be achieved by vitrifying mature oocytes rather than immature oocytes.

Abstract
Up-to-date cryopreservation is a central component of contemporary human-assisted reproduction and fertility preservation technologies. Presently, the preservation of seminal and testicular spermatozoa, embryos, and oocytes can be readily achieved with a high functional survival rate. Preservation of the ovarian cortex containing a greater number of female germ cells is an experimental procedure under extensive investigation in many centers. All these techniques are used for various purposes like optimization of assisted reproduction, provision of donor gametes, fertility preservation for cancer patients and aging women, and posthumous reproduction. Here, we present a comprehensive review of the various applications of gamete, embryo, and ovarian tissue cryopreservation and discuss their basic biological principles, practical applicability, and limitations.

Abstract
This study investigated whether failed maturation oocytes could be used to evaluate different cryopreservation procedures. A total of 289 failed maturation oocytes (GV and MI stages), obtained from 169 patients undergoing IVF treatment (mean age 33.84±5.0) were divided into two different slow-cooling groups (1.5 mol/l 1,2-propanediol+0.2 mol/l sucrose in either NaCl (group A) or choline chloride (ChCl) (group B) based cryopreservation solutions) and one vitrification group (15% ethylene glycol+15% dimethyl sulphoxide). Survival rate, in vitro maturation (IVM) rate, fertilization and developmental rate of cryopreserved oocytes were assessed. Regardless of the stage at which cryopreservation was performed (GV+MI), the slow cooling with ChCl based medium always gave significantly lower survival rate than the slow cooling in NaCl based medium (p=0.01) and vitrification (p<0.001). An extended study also showed statistically reduced survival rate between slow-cooling NaCl based medium and vitrification (p<0.05). Global results of in vitro maturation and fertilization showed worse results between both slow-cooling NaCl and ChCl based media versus vitrification. In conclusion, for oocytes that had failed to mature, vitrification gave better survival, maturation, fertilization and also cleavage rates than the slow-cooling protocols. Four cells embryos were obtained only from vitrified in vitro matured MI oocytes.

Abstract
OPINION STATEMENT Breast cancer effects nearly 200,000 American women each year, with 9% of these women still in their childbearing years. For this subset of future survivors, the issue of fertility may be a significant quality-of-life concern. Both the causes and treatments for infertility in young breast cancer patients must be thoroughly understood by the multidisciplinary team caring for these women in order for the caregivers to be effective advocates for their patients. Radiation, cytotoxic chemotherapy, and hormonal therapy all effect ovarian function to greater or lesser degrees, with the incidence of permanent post-treatment amenorrhea following systemic treatment for breast cancer in women age 50 or younger estimated as between 33% and 76%. The science of fertility preservation continues to experience significant advances in terms of the success of oocyte, embryo, and ovarian tissue preservation, and it is crucial that physicians and patients are aware of the available fertility preservation options. The optimal time to address the possibility of treatment-related infertility and strategies to combat this with younger patients is prior to treatment, rather than after cancer therapy has begun, and a full knowledge of the available technologies is a prerequisite for an informed discussion. Causes of ovarian suppression and options for treatment, including consideration of preimplantation genetic diagnosis and alternative parenting approaches are also discussed to assist the clinician caring for young patients with cancer.

Abstract
The purpose of this work is to update embryologists and clinicians on different approaches in human oocyte and embryo cryopreservation, by clarifying some misunderstandings and explaining the underlying reasons for controversial opinions. The work is based on literature review and critical analysis of published papers or conference abstracts during the last 24 years, with special focus on the last 3 years. Due to the latest advancements in techniques, cryopreservation now offers new perspectives along with solutions to many demanding problems, and has developed from a backup procedure to a successful alternative that is an indispensable constituent of assisted reproductive techniques. However, this progress is not free from controversies, at some points is rather serendipitous, and many factors, including human ones, hamper the selection and widespread application of the most efficient technique for the given task. A better understanding of the basic features of the two rival approaches (slow-rate freezing and vitrification), a clarification of terms and technical details, and a balanced, pragmatic evaluation of possible risks and potential, or definite, gains are required to accelerate advancement. Alternatively, the increasing flow of patients to the few assisted reproduction clinics and countries that are highly successful in this field will enforce the required changes in methodology and mentality worldwide.

Abstract
Cells and tissues undergo complex physical processes during cryopreservation. Understanding the underlying physical phenomena is critical to improve current cryopreservation methods and to develop new techniques. Here, we describe multi-scale approaches for modelling cell and tissue cryopreservation including heat transfer at macroscale level, crystallization, cell volume change and mass transport across cell membranes at microscale level. These multi-scale approaches allow us to study cell and tissue cryopreservation.
