Abstract
Cyclophosphamide (CP), as an anti-cancer drug, is frequently used to treat various types of cancer. A decreased number of ovarian follicles impaired normal ovarian function, and subsequent premature ovarian failure (POF) presented as a side effect of cyclophosphamide usage. These events may eventually affect the fertility rate of individuals. The present study showed the effect of cyclophosphamide on ovarian reserves and the protective effect of L-carnitine (LC) as an antioxidant to prevent POF. To design the study, six to eight-week-old NMRI female mice were divided into three groups: control, cyclophosphamide (CP), and cyclophosphamide + L-carnitine (CP + LC). Mice received drugs intraperitoneally (IP) for 21 days. In the following 24 h after the last injection, both ovaries were used to evaluate the expression of Sohlh1 and Lhx8 genes by Real-time PCR. Furthermore, the alteration of Lhx8 promoter methylation was examined by Methylation-sensitive high-resolution melting analysis (MS-HRM). The present data showed the negative effect of CP on regulator genes of oogenesis including Sohlh1 and Lhx8. In addition, an examination of the epigenetic status of the Lhx8 gene showed a change in promoter methylation of this gene following cyclophosphamide injection. Although, L-carnitine is an effective antioxidant in relieving oxidative stress caused by cyclophosphamide and its damage, in the present study, however, the use of L-carnitine failed to protect the ovaries from changes caused by CP injection. So, using cyclophosphamide can alter the expression of folliculogenesis genes through its effects on epigenetic changes and may cause POF. The results of the present study showed that L-carnitine consumption can't protect the ovaries against the adverse effects of CP.

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
RESEARCH QUESTION What are the effects of platelet lysate on structure, function and epigenetic modifications of heterotopically transplanted mouse ovarian tissues? DESIGN Mice were divided into three groups (n = 17 per group): control (mice with no ovariectomy, grafting or treatment), autograft and autograft plus platelet lysate (3 ml/kg at the graft sites). Inflammatory markers, serum malondialdehyde (MDA) concentration and total antioxidant capacity were assessed on day 7 after transplantation. Twenty-eight days after transplantation, stereological and hormonal analyses were conducted. Chromatin immunoprecipitation and quantitative real-time polymerase chain reaction were also used to quantify the epigenetic modifications of maturation genes, parallel to their expression. RESULTS The total volume of the ovary, cortex and medulla, and the number of different types of follicles, the concentration of interleukin (IL)-10, progesterone and oestradiol and total antioxidant capacity significantly decreased in the autograft group compared with the control group (P < 0.001); these parameters significantly increased in the autograft plus platelet lysate group compared with the autograft group (P < 0.001). The concentrations of tumour necrosis factor alpha, IL-6 and MDA increased significantly in the autograft group compared with the control group (P < 0.001); in the autograft plus platelet lysate group, these parameters significantly decreased compared with the autograft group (P < 0.001). In the autograft plus platelet lysate group, the expression levels of Gdf-9 (P < 0.0021), Igf-1 (P < 0.0048) and Igf-2 (P < 0.0063) genes also increased along with a lower incorporation of MeCP2 in the promoter regions (P < 0.001) compared with the autograft group. CONCLUSIONS Platelet lysate can contribute to follicular survival by improving folliculogenesis and increasing the expression of oocyte maturation genes.

Abstract
Premature ovarian failure (POF) is a common female reproductive disorder and characterized by menopause, increased gonadotropin levels and estrogen deficiency before the age of 40 years old. The etiologies and pathogenesis of POF are not fully clear. At present, hormone replacement therapy (HRT) is the main treatment options for POF. It helps to ameliorate perimenopausal symptoms and related health risks, but can't restore ovarian function and fertility fundamentally. With the development of regenerative medicine, bone marrow mesenchymal stem cells (BMSCs) have shown great potential for the recovery of ovarian function and fertility based on the advantages of abundant sources, high capacity for self-renewal and differentiation, low immunogenicity and less ethical considerations. This systematic review aims to summarize the possible therapeutic mechanisms of BMSCs for POF. A detailed search strategy of preclinical studies and clinical trials on BMSCs and POF was performed on PubMed, MEDLINE, Web of Science and Embase database. A total of 21 studies were included in this review. Although the standardization of BMSCs need more explorations, there is no doubt that BMSCs transplantation may represent a prospective therapy for POF. It is hope to provide a theoretical basis for further research and treatment for POF.

Abstract
CONTEXT Ovarian tissue transplantation is performed to preserve fertility in patients undergoing chemotherapy and radiotherapy. However, the ischemia-reperfusion injury which occurs after the ovarian tissue transplantation causes follicular depletion and apoptosis. l -Carnitine has antioxidant and anti-inflammation properties. AIMS Therefore, we aimed to investigate the beneficial effect of l -carnitine on mouse ovaries following heterotopic autotransplantation. METHODS Mice were randomly divided into three groups (six mice per group): control, autografted and autografted+l -carnitine (200mg/kg daily intraperitoneal injections). Seven days after ovary autografting, the serum levels of malondialdehyde (MDA), total antioxidant capacity, tumor necrosis factor alpha (TNF-α), interleukin (IL)-6 and IL-10 were measured. Ovary histology, serum concentrations of progesterone and estradiol were also measured 28days after autotransplantation. Data were analysed using one-way analysis of variance (ANOVA) and Tukey test, and the means were considered significantly different at P Key results: In the autografted+l -carnitine group, the total volume of the ovary, the volume of the cortex, the number of follicles, the serum concentrations of IL-10, estradiol and progesterone significantly increased compared to the autografted group. In the autografted+l -carnitine group, serum concentrations of IL-6, TNF-α and MDA were significantly decreased compared to the autografted group. CONCLUSIONS Our results indicated that l -carnitine can ameliorate the consequences of ischemia-reperfusion on the mice ovarian tissue following autotransplantation.

Carnitines as Mitochondrial Modulators of Oocyte and Embryo Bioenergetics. Antioxidants (Basel) 2022; 11:antiox11040745.

Abstract
Recently, the importance of bioenergetics in the reproductive process has emerged. For its energetic demand, the oocyte relies on numerous mitochondria, whose activity increases during embryo development under a fine regulation to limit ROS production. Healthy oocyte mitochondria require a balance of pyruvate and fatty acid oxidation. Transport of activated fatty acids into mitochondria requires carnitine. In this regard, the interest in the role of carnitines as mitochondrial modulators in oocyte and embryos is increasing. Carnitine pool includes the un-esterified l-carnitine (LC) and carnitine esters, such as acetyl-l-carnitine (ALC) and propionyl-l-carnitine (PLC). In this review, carnitine medium supplementation for counteracting energetic and redox unbalance during in vitro culture and cryopreservation is reported. Although most studies have focused on LC, there is new evidence that the addition of ALC and/or PLC may boost LC effects. Pathways activated by carnitines include antiapoptotic, antiglycative, antioxidant, and antiinflammatory signaling. Nevertheless, the potential of carnitine to improve energetic metabolism and oocyte and embryo competence remains poorly investigated. The importance of carnitine as a mitochondrial modulator may suggest that this molecule may exert a beneficial role in ovarian disfunctions associated with metabolic and mitochondrial alterations, including PCOS and reproductive aging.

Abstract
Ischemia-reperfusion (IR) injury is a major limitation of ovarian transplantation which threatens the follicular and graft survival. Taurine as a potent anti-oxidant, anti-apoptotic and anti-inflammatory agent, can prevent graft damages due to IR. We aimed to investigate the effect of taurine on the follicular survival and function of autotransplanted mouse ovaries. Female mice (4-5 weeks old) were divided into: control, autograft and autograft + taurine (200 mg/kg/day). The level of CD31 expression was evaluated two days (48 h) post transplantation. In addition, on day 7 post transplantation the serum levels of malondialdehyde (MDA) and the total antioxidant capacity (TAC) were assessed. Also, 28 days post transplantation; ovaries were studied stereologically and the percentage of apoptotic follicles, level of GDF9 expression and the serum concentrations of progesterone and estradiol were measured. Data were analyzed using one-way ANOVA and Tukey's test and the means were considered significantly different at P < 0.05. The total volume of the ovary (P < 0.01), volume of the cortex (P < 0.01) and medulla (P < 0.04), total number of different types of follicles, expression of GDF9 and CD31 and also the levels of progesterone, estradiol and TAC increased significantly in the autograft + taurine group compared to the autograft group (P < 0.001). The MDA level and apoptosis rate decreased significantly in the autograft + taurine group compared to the autograft group (P < 0.001). Taurine could significantly improve follicular survival and the function of grafted ovaries by accelerating the angiogenesis and reducing oxidative stress and apoptosis.

Abstract
Recently, transplantation of cryopreserved ovarian tissue is the method for fertility preservation for oncologic and nononcologic reasons. The main challenge of ovarian cryopreservation followed by transplantation is that ischemia reperfusion injury (IRI) induced the loss of follicles. The aim of this study was to evaluate the effects of glutathione (GSH), ulinastatin (UTI) or both (GSH+UTI) on preventing ischemia reperfusion-induced follicles depletion in ovarian grafts. Ovarian fragments were collected from 20 women aged 29±6 years. Frozen-thawed human ovarian tissue was xenografted into SCID mice, at the same time GSH, UTI and GSH+UTI was administrated respectively. The ovarian grafts were collected at the 1st, 3rd, 7th, 14th, 28th, 56th, and 85th day after xenotransplantation. Follicle survival rate was measured by H&E staining and Live/Dead staining. Angiogenic activity and macrophage recruitment was evidenced by immunohistochemical staining. The oxidative stress and inflammatory cytokines in human ovarian xenografts were measured by real-time PCR. The results indicated that after the treatments of GSH, UTI and GSH+UTI in the hosts, follicular survival in ovarian grafts were improved. The level of VEGF, CD31, and antioxidant enzymes superoxide dismutase 1 and superoxide dismutase 2 in ovarian grafts were increased. Accumulation of macrophages, level of IL6 and TNF-α, as well as malondialdehyde was decreased in ovarian grafts from treated groups. In conclusion, administration of GSH, UTI and GSH+UTI decreased the depletion of follicles in human grafts post-transplantation by inhibiting IRI-induced antiangiogenesis, oxidative stress and inflammation.

Abstract
Polycystic ovary syndrome (PCOS) is related to low levels of serum l-carnitine, which has antioxidant, anti-inflammatory and antiapoptotic properties. The aim of this study was to investigate the effect of l-carnitine on folliculogenesis in mice following induction of PCOS. PCOS was induced by daily injections of testosterone enanthate (1mg per 100g, s.c., for 35 days). NMRI mice (21 days old) were divided into four groups (n=6 per group): Control, Control+l-carnitine, PCOS and PCOS+l-carnitine. Mice were treated with 500mgkg-1, i.p., l-carnitine every second day for 28 days. Ovaries were studied stereologically and serum concentrations of FSH, LH, testosterone, interleukin (IL)-6 and tumour necrosis factor (TNF)-α were determined using ELISA kits. Serum concentrations of malondialdehyde (MDA) and the ferric ion reducing antioxidant power (FRAP) were also analysed. Apoptosis of follicles was evaluated by terminal deoxyribonucleotidyl transferase-mediated dUTP-digoxigenin nick end-labelling (TUNEL). CD31 was assessed immunohistochemically. Data were analysed using one-way analysis of variance (ANOVA) and Tukey's test, differences considered significant at P<0.05.The total volume of the ovary, cortex volume, oocyte volume, zona pellucida thickness and the number of antral follicles increased significantly, whereas the number of primary and preantral follicles decreased significantly, in the PCOS+l-carnitine versus PCOS group. In the PCOS+l-carnitine group, serum concentrations of FSH and FRAP increased significantly, whereas there were significant decreases in serum concentrations of testosterone, LH, MDA, IL-6 and TNF-α, as well as in the percentage of TUNEL-positive apoptotic cells, compared with the PCOS group. l-Carnitine improves folliculogenesis and is therefore suggested as a therapeutic supplement in the treatment of PCOS.

Abstract
Background L-carnitine (Lc) as a type of flavonoid antioxidants and bone marrow stromal cells (BMSCs) as a type of mesenchymal stem cells may recover damaged ovaries. It seems that Lc has favorable effects on differentiation, increasing lifespan and decreasing apoptosis in BMSCs. The aim of this study was to investigate effects of co-administration of BMSC+Lc on damaged ovaries after creating a chemotherapy model with cyclophosphamide in rats. Materials and Methods In this experimental study, cyclophosphamide was intraperitoneally (IP) injected to forty female wistar rats for 14 days, in terms of chemotherapy-induced ovarian destruction. The rats were then randomly divided into four groups: control, Lc, BMSCs and co-administration of BMSC+Lc. Injection of BMSCs into bilateral ovaries and intraperitoneal injection of Lc were performed individually and together. Four weeks later, levels of serum estradiol (E2) and follicle-stimulating hormone (FSH) using enzyme-linked immunosorbent assay (ELISA) kit, number of ovarian follicles at different stages using hematoxylin and eosin (H and E) staining and expression of ovarian Bcl-2 and Bax proteins using western blot were assessed. Results Co-administration of BMSC+Lc increased E2 and decreased FSH levels compared to the control group (P<0.001). The number of follicles was higher in the co-administrated group compared to the control group (P<0.001). Co-administration of BMSC+Lc increased Bcl-2 protein level, decreased Bax protein level and increased Bcl-2/Bax ratio (P<0.001). Conclusion The effect of co-administration of BMSC+Lc is probably more effective than the effect of their separate administration on the recovery of damaged ovaries by chemotherapy.

Abstract
Melatonin has anti-oxidant, anti-inflammatory and anti-apoptotic properties. We aimed to investigate the effect of melatonin on the structure and function of mice ovaries following autograft transplantation. NMRI mice were divided into: control, autografted + saline, autografted + melatonin (20 mg/kg/day i.p. injection for 1 day before until 7 days after transplantation). 28 days post transplantation, ovary compartments were studied stereologically. Follicle apoptosis and the level of progesterone and estradiol were also measured. The inflammation, serum MDA concentration and total antioxidant capacity were also assessed on day 7 post transplantation. The total volume of the ovary, cortex and medulla (P < 0.05) and the number of different types of follicles (P < 0.001), the concentration of IL-10, progesterone and estradiol (P < 0.001) and TAC (P < 0.01) significantly decreased in the autografted + saline group compared to the control. The levels of IL-6 (P < 0.01), TNF-α, MDA and the apoptotic rate (P < 0.001) increased significantly in the autografted + saline group compared to the control, while the total volume of the ovary, cortex and medulla (P < 0.05) and the number of different types of follicles (P < 0.001), the concentration of IL-10, progesterone and estradiol (P < 0.001) and TAC (P < 0.01) significantly increased in the autografted + melatonin group compared to the autografted + saline group. The levels of IL-6 (P < 0.01), TNF-α, MDA and the apoptotic rate (P < 0.001) decreased significantly in the autografted + melatonine group compared to the autografted + saline group. In the autografted + melatonin group, the localization of CD31-positive cells in the theca layer was similar to the control group. Melatonin can improve the structure and function of the grafted ovary.

Abstract
Constant progress in the diagnosis and treatment of cancer disease has increased the number and prognosis of cancer survivors. However, the toxic effects of chemotherapy and radiotherapy on ovarian function have resulted in premature ovarian failure. Patients are, therefore, still expecting methods to be developed to preserve their fertility successfully. Several potential options are available to preserve fertility in patients who face premature ovarian failure, including immature or mature oocyte and embryo cryopreservation. However, for children or prepubertal women needing immediate chemotherapy, cryopreservation of ovarian tissue is the only alternative. The ultimate aim of this strategy is to implant ovarian tissue into the pelvic cavity (orthotopic site) or in a heterotopic site once oncological treatment is completed and the patient is disease free. Transplantation of ovarian tissue with sufficiently large numbers of follicles could potentially restore endocrine function and allow multiple cycles for conception. However, the success of ovarian tissue transplantation still has multiple challenges, such as the low number of follicles in the graft that may affect their longevity as well as the survival of the tissue during ex vivo processing and subsequent transplantation. Therefore, this review aims to summarize the achievements of ovary grafting and the potential techniques that have been developed to improve ovarian graft survival.
