Abstract
This study aimed to evaluate whether the addition of vitamins E and C as two conventional antioxidants improves the cryotolerance of preantral follicles enclosed in ovine ovarian tissue slices. For this purpose, ovarian slices were obtained from abattoired juvenile lambs and randomly distributed to the following groups: fresh, toxicity, vitrified (control), and three treatment groups in two experiments. Vitamin E, vitamin C, or vitamin E + C was added to the vitrification media alone in the first experiment and added to all vitrification, warming, and culture media in the second experiment. Finally, the treated tissues were cultured in vitro for 12 hours. The histological analysis showed that single or combined use of vitamins E and C increases intact preantral follicles in comparison to the control in two experiments (p < 0.05), and simultaneous use of vitamins E and C had a synergistic effect on increasing the percentage of normal preantral follicles in experiment 2 (p < 0.05). Due to the better results in Experiment 2, stromal cell density, antioxidant activity, and molecular evaluation were followed only in this experiment. The vitamin E + C group had higher stromal cell density compared with control group (p < 0.05). Vitamin E strengthened antioxidant capacity compared with the control and vitamin C groups (p < 0.05). This effect was exacerbated when used in combination with vitamin C (p < 0.05). The expression of all evaluated genes (BMP4, BMP15, GDF9, and KITLG) was significantly increased in ovarian tissue treated with vitamin E + C compared with the control group (p < 0.05). This increase was also observed in BMP4, GDF9, and KITLG genes compared with the vitamin C group (p < 0.05). In conclusion, this study revealed the positive effects of vitamins E and C on preantral follicle viability and to some extent a synergistic action of vitamin C on the protective effects of vitamin E against preantral follicle degeneration and increasing antioxidant capacity and development of preantral follicles after ovine ovarian tissue vitrification.

Abstract
Heat stress is a significant factor affecting the fertility of dairy cattle due to the generation of free radicals. In assisted reproductive techniques, the inclusion of protective antioxidants becomes crucial to mitigate potential cellular damage. This study aimed to explore the impact of supplementing vitamins E, C, and coenzyme Q10 into the oocyte culture medium, with the goal of ameliorating the adverse effects of heat stress on oocyte maturation and embryo development in dairy cattle. A group of fifty Holstein dairy cows were synchronized, and their oocytes were harvested using the ovum pick-up method. High-quality oocytes were subjected to in vitro maturation (IVM) and in vitro fertilization (IVF) procedures, utilizing a culture medium containing, no supplements (Group 1), 100 μM of vitamins E (Group 2) and C (Group 3), along with 50 μM of coenzyme Q10 (Group 4). The ensuing zygotes were cultured, and the ensuing embryos were evaluated for blastocyst formation by the seventh day. An analysis of the blastocysts' inner cell mass (ICM) and trophectoderm (TE) cells was also conducted. The findings revealed that the group receiving supplementation of vitamin E and coenzyme Q10 exhibited significantly higher maturation and cleavage rates in comparison to both the control and the vitamin C groups. Furthermore, the count of ICM, TE, and blastocyst cells was notably elevated in the vitamin E supplemented group when compared to the control group. In summary, the effectiveness of vitamin E in enhancing IVM, IVF, and embryo development under conditions of heat stress surpassed that of vitamin C and coenzyme Q10.

Abstract
The follicle is the functional unit of the ovary, whereby ovarian development is largely dependent on the development of the follicles themselves. The activation, growth, and progression of follicles are modulated by a diverse range of factors, including reproductive endocrine system and multiple signaling pathways. The Hippo pathway exhibits a high degree of evolutionary conservation between both Drosophila and mammalian systems, and is recognized for its pivotal role in regulating cellular proliferation, control of organ size, and embryonic development. During the process of follicle development, the components of the Hippo pathway show temporal and spatial variations. Recent clinical studies have shown that ovarian fragmentation can activate follicles. The mechanism is that the mechanical signal of cutting triggers actin polymerization. This process leads to the disruption of the Hippo pathway and subsequently induces the upregulation of downstream CCN and apoptosis inhibitors, thereby promoting follicle development. Thus, the Hippo pathway plays a crucial role in both the activation and development of follicles. In this article, we focused on the development and atresia of follicles and the function of Hippo pathway in these processes. Additionally, the physiological effects of Hippo pathway in follicle activation are also explored.

Abstract
Ferroptosis is widely present in fibrosis-related diseases. The basic pathology of premature ovarian insufficiency (POI) involves ovarian tissue fibrosis, and there are currently fewer relevant studies addressing the association between ferroptosis and POI. This study aimed to demonstrate that ferroptosis induced by cisplatin (CDDP) caused ovarian tissue fibrosis, leading to POI. Vitamin E (VE), a ferroptosis inhibitor, could repair damaged ovarian function. CDDP was used to establish a rat model of POI, and VE was administered to reverse the reproductive toxicity of CDDP. Ovarian function was assessed by histological section staining, follicle counts, sex hormone levels, as well as fertility assays. The extent of ferroptosis was assessed by transmission electron microscopy (TEM), malondialdehyde (MDA), Perls staining. CCK-8, Ethynyl-2-Deoxyuridine (EdU), and scratch assays were used to determine the effect of CDDP and VE on ovarian granulosa cell (GC) viability. Western blot, quantitative reverse-transcription polymerase chain reaction (qRT-PCR) and immunohistochemistry were performed to evaluate ferroptosis-related molecular changes. Our results showed that CDDP caused follicle development disorders and ovarian tissue fibrosis, the levels of sex hormones suggested impaired ovarian function, and VE could reverse the reproductive toxicity of CDDP. The results of TEM, MDA and Perls staining suggested that the typical mitochondrial signature of ferroptosis was altered in ovarian GCs from the CDDP group, with significantly higher levels of lipid peroxidation and significant iron deposition in ovarian tissue, whereas VE mitigated the extent of ferroptosis. Molecular experiments then confirmed that the ferroptosis-related molecules acetyl CoA synthetase long chain family member 4 (ACSl4), 15-lipoxygenase-1 (ALOX15), solute carrier family 7 member 11 (SLC7A11), and glutathione peroxidase 4 (GPX4) were differentially expressed in each group. In summary, our study preliminarily demonstrated that CDDP may promote GCs to undergo ferroptosis, cause follicle development disorders, ovarian tissue fibrosis, and induce POI by regulating the expression of ACSl4, ALOX15, SLC7A11, and GPX4, while VE improved impaired ovarian function.

The protective effects of astaxanthin on pre-antral follicle degeneration in ovine vitrified/warmed ovarian tissue. Cryobiology 2023:S0011-2240(23)00024-X.

Abstract
This study assesses the protective effects of astaxanthin (AST) against vitrification/warming-induced cryoinjuries of ovarian tissue slices in sheep. Cortical slices of slaughterhouse acquired-ovine ovaries were randomly distributed in different groups: fresh, toxicity, and five vitrification groups including vitrification in presence of 0 (control group), 1, 10 and 100 μM astaxanthin or 100 μM vitamin E. After vitrification/warming and 24 h culturing, the samples were subjected to histological studies, antioxidant evaluation by TAC and TBAR assays, and assessment of relative expression of BMP4, BMP15, GDF9 and KITLG genes related to folliculogenesis and follicular growth regulation. According to the results, vitrification reduced the percentage of morphologically intact follicles compared to the fresh and toxicity groups (p < 0.05). In vitrification groups, vitamin E and all three concentrations of AST increased the percentage of intact pre-antral follicles and antioxidant activity relative to the vitrified control (p < 0.05). This enhancement significantly occurred in 10 μM AST group more than vitamin E (p < 0.05). Also, 10 μM concentration of AST enhanced the expression of all the examined genes compared to the control (p < 0.05), while the expression of BMP4, BMP15 and KITLG was higher in the AST than vitamin E (p < 0.05). The latter could increase only the expression of GDF9 compared to the control group (p = 0.011). In conclusion, AST is a highly effective antioxidant for maintaining the survival of pre-antral follicles, retaining cell density, increasing total antioxidant capacity, and increasing the expression of some genes related to follicular development after short-term culture of vitrified/warmed ovarian tissue slices.

Abstract
Oocyte cryopreservation is widely used in assisted-reproductive technology and animal production. However, cryopreservation not only induces a massive accumulation of reactive oxygen species (ROS) in oocytes, but also leads to oxidative-stress-inflicted damage to mitochondria and the endoplasmic reticulum. These stresses lead to damage to the spindle, DNA, proteins, and lipids, ultimately reducing the developmental potential of oocytes both in vitro and in vivo. Although oocytes can mitigate oxidative stress via intrinsic antioxidant systems, the formation of ribonucleoprotein granules, mitophagy, and the cryopreservation-inflicted oxidative damage cannot be completely eliminated. Therefore, exogenous antioxidants such as melatonin and resveratrol are widely used in oocyte cryopreservation to reduce oxidative damage through direct or indirect scavenging of ROS. In this review, we discuss analysis of various oxidative stresses induced by oocyte cryopreservation, the impact of antioxidants against oxidative damage, and their underlying mechanisms. We hope that this literature review can provide a reference for improving the efficiency of oocyte cryopreservation.

Abstract
Objective We investigated the effect of supplementing fertilization medium and/or culture medium with astaxanthin (AST) on the two phases of in vitro fertilization: gamete fertilization and embryo development. Methods Mouse cumulus-oocyte complexes were divided into four groups with 5 µM AST added to the fertilization medium (group 3, n=300), culture medium (group 2, n=300), or both media (group 4, n=290). No AST was added to the control group (group 1, n=300). Results The fertilization rate was significantly higher (p<0.001) in the groups using AST supplemented fertilization medium (group 3, 79.0%; group 4, 81.4%) than those without AST (group 1, 56.3%; group 2, 52.3%). The blastocyst rate calculated from the two-cell stage was significantly lower (p<0.001) in the groups using AST-supplemented embryo culture medium (group 2, 58.0%; group 4, 62.3%) than in those without AST (group 1, 82.8%; group 3, 79.8%). The blastocyst rate calculated from the number of inseminated oocytes was highest in group 3 (189/300, 63.0%) and lowest in group 2 (91/300, 30.3%) with statistical significance compared to other groups (p<0.001). There were significantly higher numbers of cells in the inner cell mass and trophectoderm, as well as significantly higher total blastocyst cell counts, in group 3 than in the control group. Conclusion An increased blastocyst formation rate and high-quality blastocysts were found only in the fertilization medium that had been supplemented with AST. In contrast, AST supplementation of the embryo culture medium was found to impair embryo development.

Abstract
BACKGROUND Mitochondria play a crucial role in nuclear maturation, fertilization, and subsequent embryo development. Cryopreservation is an important assisted reproductive technology that is used worldwide for humans and domestic animals. Although mitochondrial quantity and quality are decisive factors for successful development of oocytes and embryos, cryopreservation induces mitochondrial dysfunction. Upon thawing, the damaged mitochondria are removed, and de novo synthesis occurs to restore the function of mitochondria. Resveratrol, 3,5,4'-trihydroxystilbene, is a polyphenolic antioxidant that has versatile target proteins, among which sirtuin-1 (SIRT1) is a key regulator of in mitochondrial biogenesis and degradation. METHODS The present study is a literature review focusing on experiments involving the hypothesis that the activation of mitochondrial biogenesis and degradation following cryopreservation and warming by resveratrol may help mitochondrial recovery and improve oocyte and embryo development. MAIN FINDINGS AND CONCLUSION Resveratrol improves oocyte maturation and development and upregulates mitochondrial biogenesis and degradation. When vitrified-warmed embryos are treated with resveratrol, it helps in mitochondrial regulation and recovery of embryos from cryopreservation-induced damage. CONCLUSION Resveratrol treatment is a possible countermeasure against cryopreservation-induced mitochondrial damage.

Abstract
Abstract
Oocyte/embryo in vitro culture is one of the most important assisted reproductive technologies used as a tool for maintaining genetic resources biodiversity and the inheritance of valuable genetic resources through generations. The success of such processes affects the final goal of the in vitro culture, getting viable and healthy offspring. In common in vitro oocyte maturation and/or embryo development techniques, the development of oocytes/embryos is carried out at 5% carbon dioxide and roughly 20% atmosphere-borne oxygen ratios in cell culture incubators due to their reduced cost in comparison with low atmospheric oxygen-tension incubators. These conditions are usually accompanying by the emergence of reactive oxygen species (ROS), which can extremely damage cell membrane integrity and other vital cellular organelles, as well as genetic material. The present review mainly focuses on the antioxidant roles of different vitamins on in vitro oocyte maturation competence and embryo development in farm animals. Because, the conditions of in vitro embryo production (IVEP) are usually accompanying by the emergence of reactive oxygen species (ROS), which can extremely damage cell membrane integrity and other vital cellular organelles as well as genetic material. The use of antioxidant agents may prevent the extreme augmentation of ROS generation and enhance in vitro matured oocyte competence and embryo development. Therefore, this review aimed to provide an updated outline of the impact of antioxidant vitamin (Vit) supplementations during in vitro maturation (IVM) and in vitro fertilization (IVF) on oocyte maturation and consequent embryo development, in various domestic animal species. Thus, the enrichment of the culture media with antioxidant agents may prevent and neutralize the extreme augmentation of ROS generation and enhance the in vitro embryo production (IVEP) outcomes.

Abstract
AIM The aim of this study is to investigate the role of vitamin E in the etiology of premature ovarian insufficiency (POI). METHODS This study included a total of 96 matched cases and controls, including the case group composed of 40 women with POI, and the control group composed of 56 women with normal menstrual cycles. Serum levels of vitamin E (also known as α-tocopherol), total cholesterol, follicle stimulating hormone (FSH), luteinizing hormone (LH) and anti-Müllerian hormone (AMH) were determined. The relationship of α-tocopherol with FSH, LH and AMH levels in women were evaluated using regression models. RESULTS We found a negative association of α-tocopherol levels with FSH and LH levels, and a positive correlation between a-tocopherol and AMH levels in the whole study population. In this study, α-tocopherol levels were significantly lower in women with POI than those in women with normal menstrual cycles. CONCLUSION Vitamin E levels showed significantly statistical difference between the POI and control group (P < 0.001). Therefore, vitamin E is correlated to POI.

Abstract
Several vitrification protocols have been established for porcine oocytes so as to facilitate gene banking of female germplasm. Although live piglets have been successfully produced from pig oocytes vitrified at the germinal vesicle (GV) stage, the competence of vitrified oocytes to develop into the blastocyst stage is greatly compromised following cryopreservation. The focus of this review is to elucidate the impact of cryopreservation on the redox balance of pig oocytes, making special reference to the relevance of non-enzymatic and enzymatic antioxidant defences. Besides, the regulation of gene expression in response to oxidative stress is also considered. Finally, we discuss the effects of supplementing maturation and vitrification media with the exogenous non-enzymatic antioxidants that have hitherto yielded the most relevant results.

Abstract
Background Vitamin E, which is critically important in the whole process of reproduction, can antagonize the oxidative stress caused by the oxygen free radicals and antioxidant imbalance and regulate normal physiological function of the reproductive system. The effect of short-term supplementation of vitamin E on outcomes of infertile women with polycystic ovary syndrome (PCOS) when they underwent ovulation induction with clomiphene citrate (CC) and human menopausal gonadotropin (HMG) remains unknown. Methods This was a retrospective cohort clinical trial from October 2015 to April 2017. A total of 321 PCOS cases underwent ovulation induction with CC and HMG. Patients in group A (n = 110) did not receive vitamin E while patients in group B (n = 105) and group C (n = 106) received oral treatment of vitamin E at 100 mg/day during follicular phase and luteal phase, respectively. Results It was observed no significant differences of ovulation rate, clinical pregnancy rate, and ongoing pregnancy rate among the three groups. It was interesting that dosage of HMG were significant lower in group B compared with those in group A and group C (P<0.05). Conclusions A short-term supplementation of vitamin E can improve oxidative stress, and reduce exogenous HMG dosage to lower the economic cost with a similar pregnancy rate in the ovulation induction cycle. However, the supplementation does not alter the pregnancy rate in the ovulation induction cycle. Trial registration ChiCTR-OOC-14005389, 2014.

Abstract
AIM To evaluate the mitochondrial DNA (mtDNA) copy number, reactive oxygen species (ROS) level and intensity of mitochondrial enzyme activity in metaphase II oocytes derived from vitrified cultured immature mouse ovarian tissue in comparison with nonvitrified group and in vivo-obtained oocytes. METHODS Vitrified and nonvitrified ovaries from neonate female mice were cultured for 7 days. Then, preantral follicles were isolated and cultured in a three-dimensional culture system. Follicular development and oocyte maturation were evaluated and compared in both groups. Some of the collected metaphase II oocytes derived from in vitro and in vivo conditions were inseminated with capacitated spermatozoa, and then, the fertilization and embryo developmental rates were assessed. In the other series of oocytes, mtDNA copy number, distribution and enzyme activity and ROS level were analyzed. RESULTS The embryo development, mtDNA copy number and mitochondrial enzyme activity in collected metaphase II oocytes from two in vitro-cultured groups were significantly lower, and the ROS level was higher than those of the in vivo group (P < 0.05), but there was no significant difference between vitrified and nonvitrified groups. CONCLUSION This study showed that a two-step in vitro culture of mouse ovarian tissue decreased the mtDNA copy number and cytochrome c oxidase activity of metaphase II oocytes through an increase in their ROS level in comparison with in vivo-obtained oocytes. Thus, the in vitro culture methods should be improved.

Abstract
The aim of this study was to evaluate the effects of ovarian tissue vitrification and two-step in vitro culture on the metaphase II (MII) oocyte reactive oxygen species (ROS) level, mitochondrial transcription factor A (TFAM) expression and succinate dehydrogenase (SDH) activity. After collection of neonatal mouse ovaries, 45 ovaries were vitrified and the others (n = 45) were considered as control. All ovaries were cultured for seven days, and their isolated preantral follicles were cultured in three-dimensional culture system. After 12 days, the follicular development and oocyte maturation were evaluated and compared in vitrified and non-vitrified ovaries. The collected MII oocytes were inseminated with capacitated spermatozoa. Then, the fertilization, embryonic development, ROS level, TFAM gene expression and SDH activity of oocytes were assessed and compared. There was no significant difference between morphology and percentage of normal follicles between vitrified and non-vitrified ovaries at the beginning of culture. The follicular development and hormone level in the vitrified group was significantly lower than non-vitrified group and the ROS concentration in the vitrified group was significantly higher than non-vitrified group after one-week culture. After follicular culture, there was no significant difference in follicular development, oocyte maturation, fertilization rate, TFAM gene expression, ROS level and mitochondrial SDH activity between the groups. This study showed that ovarian tissue vitrification influences the follicular development through increase in ROS level during culture but these harmful effects may be recovered during the follicular culture period. Thus, vitrification and ovarian culture method should be improved.

Abstract
Objective The aim of present study is to determine the effects of supplementation of oocyte maturation medium with sodium
selenite (SS) on oocyte mitochondrial DNA (mtDNA) copy number and reactive oxygen species (ROS) levels.
Materials and Methods In this experimental study germinal vesicle (GV), metaphase I (MI), and metaphase II (MII)
stage oocytes were recovered from 6-8 week old female mice after superovulation. Some of the GV oocytes were
cultured and matured in the presence and absence of SS. Then in vivo and in vitro matured (IVM) oocytes were
subjected to mitochondria staining by MitoTracker green, ROS analysis, and mtDNA copy number determination using
absolute real-time polymerase chain reaction (PCR).
Results The maturation rate of GV oocytes to the MII stage significantly increased in the SS supplemented group
(79.25%) compared to the control group (72.46%, P<0.05). The intensity of mitochondrial staining was not different
among the studied groups, whereas the mitochondria distribution in the cytoplasm of the IVM oocytes showed some
aggregation pattern. The in vivo obtained MII oocytes had lower ROS levels and higher mtDNA copy numbers than
IVM-MII oocytes (P<0.05). The SS supplemented group had significantly lower ROS levels and higher mtDNA copy
numbers than the non-treated group (P<0.05).
Conclusion SS increased oocyte mtDNA copy number by decreasing oxidative stress. SS had an association with
better oocyte developmental competence.

Abstract
The developmental competence of in vitro maturation (IVM) oocytes can be enhanced by antioxidant agents. The present study investigated, for the first time in the rabbit model, the effect of adding α-tocopherol (0, 100, 200 and 400 µM) during IVM on putative transcripts involved in antioxidant defence (superoxide dismutase 2, mitochondrial (SOD2), glutathione peroxidase 1 (GPX1), catalase (CAT)), cell cycle regulation and apoptosis cascade (apoptosis tumour protein 53 (TP53), caspase 3, apoptosis-related cysteine protease (CASP3)), cell cycle progression (cellular cycle V-Akt murine thymoma viral oncogene homologue 1 (AKT1)), cumulus expansion (gap junction protein, alpha 1, 43 kDa (GJA1) and prostaglandin-endoperoxide synthase 2 (prostaglandin G/H synthase and cyclo-oxygenase) (PTGS2)) and metabolism (glucose-6-phosphate dehydrogenase (G6PD)). Meiotic progression, mitochondrial reallocation, cumulus cell apoptosis and the developmental competence of oocytes after IVF were also assessed. Expression of SOD2, CAT, TP53, CASP3 and GJA1 was downregulated in cumulus–oocyte complexes (COCs) after IVM with 100 μM α-tocopherol compared with the group without the antioxidant. The apoptotic rate and the percentage of a non-migrated mitochondrial pattern were lower in COCs cultured with 100 μM α-tocopherol, consistent with better-quality oocytes. In fact, early embryo development was improved when 100 μM α-tocopherol was included in the IVM medium, but remained low compared with in vivo-matured oocytes. In conclusion, the addition of 100 μM α-tocopherol to the maturation medium is a suitable approach to manage oxidative stress and apoptosis, as well as for increasing the in vitro developmental competence of rabbit oocytes.

Abstract
The objective of this study was to better characterize the impact of cryoprotectant exposure (temperature and sucrose supplementation) on the health and function of preantral follicles in ovarian tissues during vitrification using the domestic cat model. Ovarian cortical pieces from peri-pubertal individuals were exposed to cryoprotectants at 4 °C or room temperature and supplemented with 0 or 0.5 M of sucrose, followed by vitrification. After rapid warming, cortical pieces were cultured in vitro and assessed for normal follicular morphology, viability and resumption of transcriptional activities for up to 7 days. Throughout the culture period, follicular morphology (up to 67.5% normal follicles) and global RNA transcription (up to 50.9% follicles with transcriptional activity) in warmed tissues were improved by cryoprotectant exposure at 4 °C compared to room temperature, but viability (up to 84.6% viable follicles) did not seem to be affected by exposure temperature. Sucrose supplementation did not have a consistent effect as it increased RNA transcription but decreased normal follicular morphology. For the first time, the study demonstrated that the preservation of critical tissue functions, such as the transcriptional activities, highly depends on the temperature of the cryoprotectant exposure and not necessarily on the presence of sucrose.
