Oktay KH, Marin L. Comparison of orthotopic and heterotopic autologous ovarian tissue transplantation outcomes. Fertil Steril 2024; 121:72-79. [PMID: 37839723 PMCID: PMC11073798 DOI: 10.1016/j.fertnstert.2023.10.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Revised: 09/03/2023] [Accepted: 10/09/2023] [Indexed: 10/17/2023]
Abstract
OBJECTIVE To compare the outcomes of orthotopic and heterotopic ovarian tissue transplantation (OTT) techniques. DESIGN Mixed prospective-retrospective cohort study. SETTING Academic hospital. PATIENTS A total of 14 recipients of autologous OTT. INTERVENTIONS Of the 14 women, 12 who received orthotopic (n = 6) or heterotopic (n = 6) transplants met the inclusion criteria. All orthotopic transplants and one heterotopic ovarian tissue transplant were performed laparoscopically. Although 5 of the 6 remaining heterotopic transplants were performed subcutaneously under local anesthesia or intravenous sedation, one was performed with robotic assistance. With the exception of one recipient who solely desired restoration of endocrine function, all underwent oocyte retrieval either to cryopreserve oocytes and embryos before the graft function ceased or because they could not otherwise conceive (hysterectomy, radiation damage, and heterotopic transplant). MAIN OUTCOME MEASURES Primary outcome measures were graft function and longevity, and the number of embryos generated per retrieval. RESULTS The mean age at ovarian tissue harvesting and transplantation was lower in patients with orthotopic vs. heterotopic transplants, although the proportion of transplanted ovarian cortex was lower in heterotopic transplant cases. All grafts restored ovarian endocrine function. Fertilization rates, the number of embryos generated per retrieval, and the mean number of nonarrested embryos were significantly lower in heterotopic OTT. However, time to function and graft longevity were similar between the groups. Although 4 of the 6 women conceived and delivered 7 children among orthotopic ovarian tissue recipients, one recipient had 3 spontaneous live births after heterotopic OTT, presumably because of the induction of function in the remaining menopausal ovary. CONCLUSIONS It appears that orthotopic OTT results in higher gamete and embryo quality. However, the endocrine function restoration rate and longevity are similar between the 2 approaches. When feasible, orthotopic OTT should be preferred for those who intend to conceive, although a less invasive heterotopic OTT can be performed for those who primarily desire ovarian endocrine function.

Abstract
Preservation of ovarian tissues is an effective way to ensure genetic diversity of susceptible natural bird populations that are in danger of extinction. We examined whether the addition of the plant phenol resveratrol to vitrification solutions ameliorates the damaging effects of tissue hypoxia and reperfusion injury when the tissues are transplanted. Duck ovary tissues were frozen in the presence of varying concentrations of resveratrol in cryopreservation solutions and then transplanted under the renal capsules of 2-day-old Shelducks. Samples of the transplanted tissues were examined on days 3- and 9- post transplantation for activation of hypoxia-, antioxidant- and apoptosis-related gene expression and apoptosis. Resveratrol significantly increased expression of VEGF, HIF-1α, Nrf2, CAT and Bcl-2 mRNA and decreased BAX and Caspase-3 mRNA and reduced numbers of TUNEL-positive cells after vitrification and heterotopic ovarian transplantation. Resveratrol improved the antioxidant capacity, reduced apoptosis and activated the HIF-1α/VEGF pathway to promote angiogenesis 3- and 9-days following transplantation. These results indicated that the addition of resveratrol to vitrification solutions intended for long-term cryopreservation of ovary tissues improves survival in storage and the grafts following transplantation. This study provides a theoretical basis for the successful transplantation of avian ovarian tissue after vitrification.

Abstract
Heterotopic and orthotopic ovarian tissue autotransplantation techniques, currently used in humans, will become promising alternative methods for fertility preservation in domestic and wild animals. Thus, this study describes for the first time the efficiency of a heterotopic ovarian tissue autotransplantation technique in a large livestock species (i.e., horses) after ovarian fragments were exposed or not to a cooling process (4°C/24 h) and/or VEGF before grafting. Ovarian fragments were collected in vivo via an ultrasound-guided biopsy pick-up method and surgically autografted in a subcutaneous site in both sides of the neck in each mare. The blood flow perfusion at the transplantation site was monitored at days 2, 4, 6, and 7 post-grafting using color-Doppler ultrasonography. Ovarian grafts were recovered 7 days post-transplantation and subjected to histological analyses. The exposure of the ovarian fragments to VEGF before grafting was not beneficial to the quality of the tissue; however, the cooling process of the fragments reduced the acute hyperemia post-grafting. Cooled grafts compared with non-cooled grafts contained similar values for normal and developing preantral follicles, vessel density, and stromal cell apoptosis; lower collagen type III fibers and follicular density; and higher stromal cell density, AgNOR, and collagen type I fibers. In conclusion, VEGF exposure before autotransplantation did not improve the quality of grafted tissues. However, cooling ovarian tissue for at least 24 h before grafting can be beneficial because satisfactory rates of follicle survival and development, stromal cell survival and proliferation, as well as vessel density, were obtained.

Abstract
An appropriate implantation site favors angiogenesis and avoids ovarian tissue damage after tissue grafting. The objective of this study was to evaluate the effects of intramuscular (IM) and subcutaneous (SC) sites for ovarian grafts in goats by evaluating follicular morphology and activation, preantral follicle and stromal cell densities, tissue DNA fragmentation, collagen types I and III depositions, and graft revascularizations. Ovarian cortical tissue was transplanted in IM or SC sites and recovered 7 or 15 days post-transplantation. There was a greater percentage of developing follicles and lesser follicular and stromal cell densities in all grafted tissues as compared to ovarian tissues of the control group. The stromal cell density and percentage of normal follicles were positively associated. At 15 days post-transplantation, tissues at the SC and IM sites had similar amounts of DNA fragmentation and type III collagen content. In contrast, tissues at the SC, as compared with IM site, had greater abundances of collagen type I. Furthermore, there was a positive association between collagen type I and percentage of morphologically normal follicles post-transplantation. In addition to a marked decrease in follicular density 15 days post-transplantation in ovarian grafts at the SC and IM sites, low percentages of normal follicles and follicular activation were observed similarly in both transplantation sites. There were also positive associations of stromal cell density and abundance of type I collagen fibers with the percentage of intact follicles in grafted ovarian tissues.

Abstract
Cancer survivorship rates have drastically increased due to improved efficacy of oncologic treatments. Consequently, clinical concerns have shifted from solely focusing on survival to quality of life, with fertility preservation as an important consideration. Among fertility preservation strategies for female patients, ovarian tissue cryopreservation and subsequent reimplantation has been the only clinical option available to cancer survivors with cryopreserved tissue. However, follicle atresia after transplantation and risk of reintroducing malignant cells have prevented this procedure from becoming widely adopted in clinics. Herein, we investigated the encapsulation of ovarian follicles in alginate hydrogels that isolate the graft from the host, yet allows for maturation after transplantation at a heterotopic (i.e., subcutaneous) site, a process we termed in vivo follicle maturation. Survival of multiple follicle populations was confirmed via histology, with the notable development of the antral follicles. Collected oocytes (63%) exhibited polar body extrusion and were fertilized by intracytoplasmic sperm injection and standard in vitro fertilization procedures. Successfully fertilized oocytes developed to the pronucleus (14%), two-cell (36%), and four-cell (7%) stages. Furthermore, ovarian follicles cotransplanted with metastatic breast cancer cells within the hydrogels allowed for retrieval of the follicles, and no mice developed tumors after removal of the implant, confirming that the hydrogel prevented seeding of disease within the host. Collectively, these findings demonstrate a viable option for safe use of potentially cancer-laden ovarian donor tissue for in vivo follicle maturation within a retrievable hydrogel and subsequent oocyte collection. Ultimately, this technology may provide novel options to preserve fertility for young female patients with cancer.

Comparison of the Oocyte Quality Derived from Two-Dimensional Follicle Culture Methods and Developmental Competence of In Vitro Grown and Matured Oocytes. BIOMED RESEARCH INTERNATIONAL 2018; 2018:7907092.

Abstract
In vitro follicle growth (IVFG) is an emerging fertility preservation technique, which can obtain fertilizable oocytes from an in vitro culture system in female. This study aimed to compare efficiency of the most widely used two-dimensional follicle culture methods [with or without oil layer (O+ or O- group)]. Preantral follicles were isolated from mice and randomly assigned. Follicles were cultured for 10 days and cumulus-oocyte complexes harvested 16-18 hours after hCG treatment. Follicle and oocyte growth, hormones in spent medium, meiotic spindle localization, expression of reactive oxygen species (ROS), mitochondrial activity, and gene expression were evaluated. In follicle growth, survival, pseudoantral cavity formation, ovulation, and oocyte maturation were also significantly higher in O+ group than O- group. Hormone production was significantly higher in follicles cultured in O+ than O-. There were no significant differences in mRNA expression related to development. On the other hand, the level of ROS was increased while the mitochondrial activity of in vitro grown matured oocyte was less than in vivo matured oocytes. In conclusion, follicle culture with O+ group appears to be superior to the culture in O- group in terms of follicle growth, development, oocyte growth, maturation, and microorganelles in oocyte.

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.

Abstract
ABSTRACT: This study aimed to evaluate the characteristics of two different murine models of hormone-treated renal-encapsulated bovine ovarian tissue xenotransplantation. Two immunodeficient mouse models (BALB/c Nude and C57BL6 SCID) were xenografted with ovarian pieces from heifers and each group was subjected to two hormonal treatments of eCG or a combination of FSH+LH. Donor ovaries and recipients were evaluated by histology and infrared thermography at different times. At the time of xenograft collection, animals were evaluated for alterations in hepatorenal biochemistry. The statistical test used in the study was ANOVA, followed by Tukey’s test. Among the strains, 80% of C57BL6 SCID and 77% of BALB/c Nude mice showed development and vascularization of the transplanted tissue, which acquired cyclicity at 19 and 9 days post-transplant, respectively. Hemorrhagic follicles in xenografts induced with FSH+LH were found in the C57BL6 SCID strain. Infrared thermography was insufficient to distinguish the tissue donor recipient. In conclusion, the C57BL6 SCID strain appears to be the best host for ovarian xenografts, since the transplants in these mice were viable and showed robust follicular development. This work will aid future choices of immunodeficient strains for xenografting procedures.

Abstract
Backgroud Ovarian transplantation is a useful method for preserving the fertility of young women with cancer who undergo radiotherapy and chemotherapy. Follicle-stimulating hormone (FSH) is use to protect transplanted ovarian tissues from ischemia injury through promoting revascularization after transplantation, but the side effect of high level FSH is ovarian overstimulation leading to substantial follicular loss. In this study, we investigated the optimal usage of FSH on revascularization in the in vitro cultured ovarian tissues before and after transplantation. Results FSH mainly exhibited an additive response in the gene and protein expression of vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF) and follicle stimulating hormone receptor (FSHR) with its raised concentrations (0.15 IU/ml, 0.30 IU/ml and 0.60 IU/ml) and prolonged treatment (3 h, 6 h, 12 h, 24 h). The concentrations with 0.60 IU/ml FSH could obviously promoted the expression of VEGF, bFGF and FSHR, but under this concentration FSH could also overstimulated the ovarian tissue leading to follicular loss. With the increase of culture time, the gene and protein expression of VEGF and bFGF both were up-regulated in all of the FSH added groups, but FSHR expression decreased when culture time exceeded 12 h. So we chose 0.30 IU/ml FSH added concentration and 6 h culture time as the FSH usage condition in functional revascularization verification experiment, and found that under this condition FSH promoted 2.5 times increase of vascular density in treated group than in control group after ovarian tissues transplantation. Conclusion Ovarian intervention with 0.30 IU/ml FSH for 6 h is an optimal FSH usage condition which could accelerate the revascularization in the allotransplanted ovarian tissue and can not produce ovarian overstimulation.

This study was conducted to investigate the effect of the vascular endothelial growth factor (VEGF) and fibroblast growth factor 2 (FGF2) on revascularization, survival, and oocyte quality of cryopreserved, subcutaneously-transplanted mouse ovarian tissue. Autologous subcutaneous transplantation of vitrified-thawed mouse ovarian tissues treated with (experimental group) or without (control group) VEGF and FGF2 was performed. After transplantation to the inguinal region for two or three weeks, graft survival, angiogenesis, follicle development, and oocyte quality were examined after gonadotropin administration. VEGF coupled with FGF2 (VEGF/FGF2) promoted revascularization and significantly increased the survival rate of subcutaneously-transplanted cryopreserved ovarian tissues compared with untreated controls. The two growth factors did not show long-term effects on the ovarian grafts. In contrast to the untreated ovarian grafts, active folliculogenesis was revealed as the number of follicles at various stages and of mature oocytes in antral follicles after gonadotropin administration were remarkably higher in the VEGF/FGF2-treated groups. Although the fertilization rate was similar between the VEGF/FGF2 and control groups, the oocyte quality was much better in the VEGF/FGF2-treated grafts as demonstrated by the higher ratio of blastocyst development. Introducing angiogenic factors, such as VEGF and FGF2, may be a promising strategy to improve revascularization, survival, and oocyte quality of cryopreserved, subcutaneously-transplanted mouse ovarian tissue.

Abstract
This study evaluated the remote ischemic preconditioning (R-IPC) early and late repercussion on fresh ovarian transplants, aiming to assess a probable protective effect in ovarian follicular pool. Sixty Wistar EPM-1 rats were used, divided in 2 study groups: ovarian transplantation (Tx) and Tx + R-IPC, submitted to ovary transplant with or without R-IPC, respectively. These groups were subdivided according to the date for euthanasia: 4th, 7th, 14th, 21st, and 30th days of the postoperatory period. Morphology, morphometry, neoangiogenesis (vascular endothelial growth factor [VEGF]), proliferative activity (Ki-67), and apoptosis (cleaved caspase-3) were evaluated. Remote ischemic preconditioning was performed in the common iliac artery. Fresh autologous ovarian tissue was implanted integrally in the retroperitoneum. All animals showed resumption of estrous phase after ovary transplantation. Remote ischemic preconditioning attenuated the lesions progressively from the 7th day, with greater number of the immature follicles (14 days, P < .05), but didn't affect mature follicles and corpora lutea (P > .05). Immunohistochemical analyzes, taken as a whole, show that R-IPC benefic effect is more evident in the later periods of evaluation, when a greater proliferative activity (14, 21, and 30 days, P < .05) and lesser cell apoptotic activity (21 and 30 days, P < .05). The VEGF expression was similar in all times (P > .05). Remote ischemic preconditioning could have a benefic effect in the progressive evaluation of freshly grafted ovarian, especially on the latest phases of the posttransplant period. The 14th day was a landmark in the recuperation of the graft. Further investigations are necessary to determine the role of R-IPC in this scenario and its effect in frozen-thawed ovarian tissue.

Abstract
STUDY QUESTION Does the preoperative administration of simvastatin and methylprednisolone enhance mouse ovarian quality after auto-transplantation of vitrified-warmed ovarian tissue (OT)? SUMMARY ANSWER Treatment with combined simvastatin and methylprednisolone enhances the quality of transplanted mouse OTs. WHAT IS KNOWN ALREADY The prevention of ischemic injury after transplantation of OT is critical for preserving the ovarian follicles. Preoperative administration of simvastatin (a cholesterol-lowering drug) has beneficial effects on various organ transplantations. Moreover, donor treatment with simvastatin and methylprednisolone (main effects are on immune response) prevents ischemia-reperfusion injury and has a beneficial effect on allograft survival in rat cardiac allografts. STUDY DESIGN, SIZE, DURATION A total of 232 6-week-old B6D2F1 mice were randomly distributed into fresh control, vitrified-warmed control and experimental groups (n = 10-17 per group). The experimental groups were as follows: sham control, simvastatin, methylprednisolone and co-treatment groups. In the experimental groups, the mice were administered simvastatin (5 mg/kg, orally), methylprednisolone (15 mg/kg, i.v.) or a combination of simvastatin and methylprednisolone 2 h before ovariectomy, whereas the sham control mice received normal saline. PARTICIPANTS/MATERIALS, SETTING, METHODS Whole ovaries were removed from the mice and vitrified by two-step vitrification procedures. The vitrified ovaries were warmed 1 week later and auto-transplanted under the bilateral kidney capsules. The ovaries and blood samples were collected 2, 7 and 21 days (D) after transplantation for histological analysis, terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling assay, immunohistochemistry for CD31 and serum anti-Mullerian hormone (AMH) level estimation. Embryonic development was evaluated after IVF of oocytes obtained from the transplanted ovary. MAIN RESULTS AND THE ROLE OF CHANCE The group that received simvastatin and methylprednisolone showed a significantly improved intact (Grade 1) follicle ratio (D2: P < 0.001, D7: P < 0.05 and D21: P < 0.001), apoptotic follicle ratio (D21: P < 0.05), CD31-positive area (D7: P < 0.05 and D21: P < 0.05) and serum AMH level (D7: P < 0.001) after transplantation when compared with the sham control. However, no difference was noted in the fertilization and blastocyst formation rates, number of total and apoptotic blastomeres per blastocyst and inner cell mass/trophectoderm ratio among the four transplantation groups. LIMITATIONS, REASONS FOR CAUTION Although we evaluated the beneficial effects of simvastatin and methylprednisolone in the present study, we did not unravel the corresponding protective mechanisms. WIDER IMPLICATIONS OF THE FINDINGS Our results suggest that a combination of simvastatin and methylprednisolone has beneficial effects on the quality and functioning of transplanted OT. This combined treatment can potentially be applied clinically to humans and domestic animals subject to further studies.

Abstract
Many studies have shown that ischemic injuries during the transplantation process were more detrimental than cryoinjuries for follicle survival and death, and it has been reported that transplantation sites can affect the outcomes of grafted ovarian tissue (OT). The purpose of this study was to assess the impact of different OT transplantation sites on follicular integrity and function of OT grafts. B6D2F1 mice were randomly assigned to control (sham) and four experimental groups according to transplantation sites (back muscle [BM], fat pad [FP], kidney capsule [KC], and subcutaneous [SC]). The ovaries from four groups were autotransplanted to each site. The OT recovery ratios on Days 2, 7, and 21 were significantly decreased in the FP group. The mean numbers of follicles were significantly lower in all the grafting groups compared with the sham group, except in the KC group on Days 7 and 21 and the BM group on Day 21. On Day 2, all the experimental groups showed low intact (G1) follicle ratio when compared with the sham group; however, the BM, KC, and FP groups recovered their morphologic integrity on Day 7, and only the SC group presented a significant decrease in G1 follicle ratios. On Day 21, the G1 follicle ratios of the FP and KC groups were greater than the sham control group. The proportion of apoptotic follicles of the four OT graft groups was higher than in the sham group on Day 2, followed by a significant decrease in the KC group and an increase in the SC group on Day 7. The serum follicle-stimulating hormone levels were significantly increased in all grafting groups on Day 2. On Day 7, only the SC group showed the high follicle-stimulating hormone level compared with the other groups. The mean numbers of oocytes from OT grafts were the highest in the KC group, except in the control group, and the lowest in the SC group. The ratios of mature oocytes were also significantly greater in the sham and KC groups. However, the ratios of normal spindle did not differ among the five groups. In conclusion, the KC was the optimal site for OT transplantation in this murine model, whereas the SC site was unfavorable for this procedure. In this study, we confirmed that the different grafting sites influenced the outcomes of transplantation.

Abstract
BACKGROUND Current strategies in cancer treatment have markedly increased the rates of remission and survival for cancer patients, but are often associated with subsequent sterility. While there are various options available to an adult female depending on the patient's particular situation, the only realistic option for preserving fertility in prepubertal females is to cryopreserve ovarian tissue. This is the first report of a morphologically mature oocyte collected from non-stimulated prepubertal ovarian tissue xenotransplants. METHODS Ovarian tissue from a 6 year old patient suffering from nephroblastoma was removed and cryopreserved for fertility preservation. The frozen-thawed ovarian tissue fragments were xenotransplanted to bilaterally oophorectomized severe combined immunodeficiency (SCID) mice to assess follicle development. RESULTS Antral follicle formation occurred post-xenotransplantation in a single ovarian fragment without exogenous hormone stimulation. A morphologically maturing oocyte was harvested from these follicles. CONCLUSIONS Prepubertal human ovarian follicles and oocytes can be matured after xenotransplantation even without exogenous hormone stimulation. These results indicate that tissue collected from prepubertal patients can support fertility in cancer survivors.

Abstract
Cancer treatments can induce premature ovarian failure in almost half of young women suffering from invasive neoplasia. Cryopreservation of ovarian cortex and subsequent autotransplantation of frozen-thawed tissue have emerged as promising alternatives to conventional fertility preservation technologies. However, human ovarian tissue is generally harvested before the administration of gonadotoxic treatment and could be contaminated with malignant cells. The safety of autotransplantation of ovarian cortex remains a major concern for fertility preservation units worldwide. This paper discusses the main tools for detecting disseminated cancer cells currently available, their limitations, and clinical relevance.

Abstract
PURPOSE To investigate the effect of graft site and gonadotrophins administration on the number and survival rate of follicles of canine ovarian grafts transplanted to NOD-severe combined immune deficiency (SCID) mice. METHODS Fresh ovarian cortex slices obtained from immature bitches were grafted subcutaneously (SC), under kidney capsule (KC) or into ovarian bursa (OB) in NOD-SCID mice. Two months after surgery, the mice allocated into non-treated and treated gonadotrophins groups that injected with porcine follicle stimulating hormone during 7 days and human chorionic gonadotrophin 48 h later. Ovarian grafts were collected after 10 h of last injection and processed for histology. RESULTS The number of transitional and preantral follicles under KC and into OB was significantly higher in gonadotrophins-treated mice than those who received saline. Furthermore, the survival rates of primary, transitional and preantral follicles under KC and into OB grafts were significantly higher than those placed SC in the treated gonadotrophins group, and in the non-treated gonadotrophins group; the proportion of primary and preantral follicle survival was significantly higher under KC and into OB than SC grafts. CONCLUSIONS In canine ovarian xenografting, administration of gonadotrophin could be effective for improvement of survival of transplanted ovary. Furthermore, the grafting into OB appeared to be better than grafting under KC, which in turn is better than SC.

Abstract
Purpose The aim of this study was to investigate the survival and development of premature follicles and oocytes from a vitrified-transplanted ovary in a murine experimental model. Methods The 14-day-old mice were unilaterally ovariectomized and the separated ovaries were vitrified by cryotop. After 2 weeks the ovaries were warmed and autotransplanted into the gluteus superfiscialis muscle. After 3 weeks, these ovaries (vit-trans), the ovaries from the opposite side (OPP), and 7-week fresh mouse ovaries as sham and control group (7 week-fresh), were recovered and examined histologically and by TUNEL test. Results All 4 vitrified-autotransplanted ovaries had developing follicles. Primordial, primary, preantral and antral follicles were found in all three groups (7 week-fresh, OPP and vit-trans). The rate of apoptosis by TUNEL test was similar in all groups and no significant difference was found between vitrified-transplanted ovarian tissue and controls. Conclusions These data demonstrate successful autotransplantation of vitrified whole mouse ovaries, manifested by the presence of all stages of folliculogenesis. According to the results of this experiment, heterotopic autotransplantation of whole cryopreserved ovary provides the opportunity for follicle development at all stages. However, further experiments are required to improve the efficiency of autotransplantation of cryopreserved ovaries to obtain better results.

Abstract
The influence of graft site on the survival of canine follicles and oocytes after autografting was investigated. Hemi-ovaries were autografted to three locations (quadriceps femoris muscle fascia, kidney capsule, and gastrosplenic ligament), and grafted ovaries were recovered (under anesthesia) 28 to 31 d after transplantation. The grafted hemi-ovaries were bisected: one-quarter ovary was used for histological assessment and another quarter for evaluation of oocyte viability. As controls, the remaining fresh hemi-ovaries were used to assess the viability of follicles and oocytes in non-transplanted ovaries. Most follicles in the histological sections of the grafts were classified as primordial or primary follicles. Antral follicles were not observed in the grafts, irrespective of the graft site. The percentages of viable follicles in the sections from control ovaries, and the ovaries grafted to the kidney capsule, the quadriceps femoris muscle fascia, and the gastrosplenic ligament were 17.4, 22.9, 18.3, and 32.4%, respectively. A total of 12 oocytes was recovered from the 15 hemi-ovaries grafted in five bitches, of which five (41.7%) oocytes from the ovaries grafted to the quadriceps femoris muscle fascia and the kidney capsule were cultured for assessment of meiotic competence. Three oocytes were viable but remained in the germinal vesicle stage after 72 h of maturation culture. The quadriceps femoris muscle fascia might be useful for grafting like the kidney capsule, but improvement of follicle survival and meiotic competence of oocytes in the grafts is necessary.

Abstract
Ovary grafting is not only a method of investigating follicle and oocyte development, but also a useful model to explore the possibility of the re-establishment of the reproductive axis in male-to-female sexual reversal. This study investigated ovary survival and follicle development after mouse ovaries were transplanted into immune-intact castrated male mice. Ten-day-old mouse ovaries were transplanted into the back muscle of adult outbred castrated male mice treated with immunosuppressants. Twenty-two days later, the ovary structure and the number of follicles present was examined by hematoxylin and eosin staining. The oocytes were harvested, and then used for in vitro maturation (IVM) and IVF. The results showed that primordial and antral follicles were mainly found in the grafts, and there were obvious differences compared with 32-day-old fresh ovaries (P<0.05). Embryos were derived from collected oocytes after IVM and IVF with a 72.4% cleavage rate and 7.9% blastocyst rate; 12 live pups were generated by embryo transfer. The hormone assay showed that plasma concentrations of both estrogen and progesterone increased after ovarian transplantation (P<0.01). In conclusion, immune-intact adult castrated male mice can support ovary survival and further development of follicles with endocrine function after ovarian transplantation.

Abstract
The functional longevity of cryopreserved ovarian grafts is one of the most challenging questions regarding ovarian transplantation at present. This study used a rat ovarian grafting model to investigate whether ovarian tissues from adult rats, which had been cryopreserved by vitrification and followed by heterotopic transplantation, could establish long-term hormone secretion and follicle development. Fresh and cryopreserved ovarian tissues were autologously transplanted under the kidney capsule. One-third of the animals in each group (sham-operated, fresh autografts, cryopreserved autografts, or castrated) were killed 5, 8, or 10 months after transplantation. Vaginal cytology, serum estradiol (E2), progesterone, and the morphology of the reproductive tract were used to assess ovarian function. Both fresh and cryopreserved ovarian grafts survived well in all the animal models with comparable proportion of follicles at each stage of folliculogenesis at all three time points. The serum E2 and progesterone concentrations in the groups with fresh or cryopreserved grafts remained comparable with those in sham-operated controls at all investigated time points. However, a loss of grafts and primordial follicles following heterotopic transplantation was noted. In conclusion, the heterotopic autotransplantation of vitrified ovarian tissues from adult rat without vascular anastomosis can maintain long-term ovarian function and exert endocrine function in target organs, in spite of the reduction in follicle pool.

Abstract
BACKGROUND Transplantation of ovarian tissue is, at present, the only clinical option available to restore fertility using cryopreserved ovarian tissue. More than 30 transplantations of cryopreserved tissue have been reported, and six babies have been born, worldwide, following this procedure. Despite these encouraging results, it is essential to optimize the procedure by improving the follicular survival, confirming safety and developing alternatives. Here, we review the different factors affecting follicular survival and growth after grafting. METHODS Relevant studies were identified by searching Pubmed up to January 2009 with English language limitation. The following key words were used: (ovarian tissue or whole ovary) AND (transplantation) AND (cryopreservation or pregnancy). Using the literature and personal experience, we examined relevant data on the different exogenous and clinical factors affecting follicular development after grafting. RESULTS Clinical factors such as the patient's age and the transplantation sites influenced the lifespan of the graft. A heterotopic transplantation site is not optimal but offers some advantages and it may also promote the hormonal environment after a combined heterotopic and orthotopic transplantation. Exogenous factors such as antioxidants, growth factors or hormones were tested to improve follicular survival; however, their efficiency regarding further follicular development and fertility potential remains to be established. CONCLUSION Additional evidence is required to define optimal conditions for ovarian tissue transplantation. Alternatives such as whole ovary or isolated follicles transplantations require further investigation but are likely to be successful in humans in the future.

Abstract
The quality of oocytes derived from rabbit ovarian grafts after cryopreservation and mesometrial autotransplantation was assessed according to the capacity to develop into offspring and the incidence of chromosome abnormalities of blastocyst embryos after fertilization. Ovarian cryopreservation and mesometrial transplantation do not affect the chromosome complement of blastocysts derived from oocytes grown in ovarian grafts, and oocytes retrieved from mesometrial grafts produce live offspring after fertilization.

Abstract
PURPOSE To analyze the gap junction proteins connexin 37 (Cx37) and connexin 43 (Cx43) after subcutaneous transplantation of cryopreserved mouse ovarian tissue. METHODS Expression of gap junction genes was assessed by immunohistochemistry and real-time polymerase chain reaction (PCR) in transplanted cryopreserved ovarian tissue compared with that of normal ovarian tissue. Apoptosis of ovarian cells was evaluated by using the terminal deoxynucleotidyl transferase-mediated biotinylated deoxyuridine triphosphates nick end-labeling method. RESULTS After subcutaneous transplantation, Cx37 and Cx43 mRNA and protein expression were significantly lower in cryopreserved than in normal ovarian tissue. Apoptosis was increased in granulosa cells from antral follicles of the cryopreserved tissue. CONCLUSION After cryopreservation and subcutaneous transplantation of ovarian tissue, proteins forming gap junctions between oocytes and granulosa cells are under-expressed compared with normal controls.

Follicle survival and growth to antral stages in short-term murine ovarian cortical transplants after Cryologic solid surface vitrification or slow-rate freezing. Cryobiology 2008; 57:163-9.

Abstract
This study was designed to asses murine preantral follicle survival and growth, after cryopreservation of ovarian tissue by two different methodologies, solid-surface vitrification by the Cryologic vitrification method (CVM) and slow-rate freezing (SRF). Cryotreated tissue was stored in liquid nitrogen for 24h, and upon warming follicle viability was assessed by live/dead fluorescent probes, and by 7-day autotransplantation of both cryotreated tissue types to the left and right kidney capsule of the donor animals (n=16). The live/dead assay immediately upon tissue warming did not allow a distinction to be made in terms of follicle viability between the CVM and SRF cryoprocedure. In grafted tissue, follicular survival and growth was assessed by conventional histological examination and proliferating cell nuclear antigen immunohistochemistry. In each experimental group (control, CVM and SRF), follicles were classified according to developmental stage, and a comparison of the proportions of follicle stages between the three groups was executed by statistical analysis of variance. The fraction of primordial follicles in CVM and SRF grafts significantly decreased as compared to control tissue, whereas intermediary and primary follicles significantly increased. The proportion of secondary and antral follicles after SRF was significantly larger than after CVM, but did not differ significantly between CVM and control tissue. The observed massive follicle activation is a typical transplantation effect, but testifies to the survival of cryopreserved follicles. In both types of cryotreated tissue, growing follicles, including antral stage, were present in grafts from all recipient animals. The significantly more abundant further developed stages in SRF treated tissue, however, suggest that CVM treated tissue may have suffered a growth disadvantage. To our knowledge, this is the first time that the CVM technique has been utilized to vitrify preantral follicles.

Abstract
PURPOSE To morphologically evaluate the estrogenic effect on the uterus and vagina of rats submitted to ovarian autografts. METHODS Twenty Wistar EPM-1 adult rats were bilaterally ovariectomized, followed by ovarian transplants in retroperitoneal regions. The animals were divided in four groups of five animals, according to the day of euthanasia: G4, G7, G14 and G21, corresponding to the 4th, 7th, 14th and 21st day after surgery, respectively. Vaginal smears were collected from the first day of surgery until euthanasia day. After that, the vagina and uterus were removed, fixed in 10% formaldehyde and submitted to histological analysis and stained with hematoxiline and eosine. RESULTS All animals showed estrous cycle changes during the experiment. In 4th day, the uterus showed low action of estrogen with small number of mitosis and eosinophils as well as poor development. On the 7th day, the endometrium was atrophic without mitotic signals and presented a small number of eosinophils. On the 14th and 21th days the histological findings were similar, with the presence of mitosis in the endometrial glands and intense leucocyte infiltration with a large number of eosinophils. Morphometric results showed that the endometrial and myometrial thickness as well as the number of eosinophils presented the highest values during the 14th and 21th days of the evaluation. The 7th day group also presented the lowest eosinophil numbers. Vaginal epithelium features were: 4th and 7th day groups presented non-keratinized stratified epithelium with 5 and 2 cell layers, respectively. The 14th and 21st day groups presented non-keratinized stratified epithelium with 14 and 15 cell layers. CONCLUSION Experimental ovarian autografts in the evaluated organs presented maximum estrogen activity after the 21st day of surgery, according to morphological and morphometric data.

Abstract
Embryo development after homologous intracytoplasmic sperm injection (ICSI) with sperm from testis tissue xenografts from pigs or any other farm animal species has not been evaluated critically. Here, we report development of porcine embryos in vitro following ICSI with sperm retrieved from xenografted neonatal pig testis. Small pieces of testis tissue from newborn piglets were grafted under the back skin of castrated immunodeficient mice (n = 4) and the xenografts were collected 8 months after grafting. Spermatozoa were recovered by mincing of the grafted tissue. For comparison, testicular, epididymal and ejaculated spermatozoa were also collected from mature boars. Oocytes injected with xenogeneic spermatozoa were either fixed to determine fertilisation processes (n = 89 in five replicates) or allowed to develop in vitro (n = 143 in four replicates). Xenogeneic porcine spermatozoa were fertilisation competent (24% v. 58%, 68%, 62% or 0% for xenogeneic v. control testicular, epididymal and ejaculated spermatozoa or no spermatozoa, respectively) and embryos developed to the blastocyst stage (8% v. 22%, 27%, 25% or 0%, respectively). These results demonstrate that porcine spermatozoa derived from immature testis tissue xenografted into mice are fertilisation competent, albeit at a lower rate than testicular, epididymal or ejaculated spermatozoa from control boars, and support embryo development after ICSI.

Abstract
Cancer is not the only disease where the question of the female fertility preservation is asked. In autoimmune diseases, alkylating agents are also used and it is now established that 20 g as a cumulative dose of cyclophosphamide is associated with premature ovarian failure in 50% of 20-year-old patients. Several strategies are discussed and offered to these patients to prevent the ovarian failure: GnRH agonist treatment, in vitro fertilization and embryos cryopreservation, oocytes cryopreservation and ovarian cortex cryopreservation. These techniques might also be associated one with the other. A survey was conducted in France in order to assess the practices realised in these diseases. Four centres were asked for these diseases, concerning 17 patients (mean age: 26.2 +/- 1.8 SEM [15-43]) and systemic lupus erythematosus was the most frequent disease (7/17). Ovarian cortex cryopreservation was realised for 6 patients. Embryos or oocytes cryopreservation was realised for 2 patients including one where ovarian cortex cryopreservation was associated. In 10 cases, considering the treatment and the patient's wish no fertility preservation was realised. Female fertility preservation in autoimmune diseases is a difficult question and a national registry, such as the one conducted by the GRECOT, can help to answer this question.

Abstract
The review covers current options for ovarian tissue cryopreservation and transplantation and provides a systematic review of the existing literature from the last 10 years, taking into account all previously published reviews on the subject. The different cryopreservation options available for fertility preservation in cancer patients are embryo cryopreservation, oocyte cryopreservation and ovarian tissue cryopreservation. The choice depends on various parameters: the type and timing of chemotherapy, the type of cancer, the patient's age and the partner status. The different options and their results are discussed, as well as their putative indications and efficacy. The review concludes that advances in reproductive technology have made fertility preservation techniques a real possibility for patients whose gonadal function is threatened by premature menopause, or by treatments such as radiotherapy, chemotherapy or surgical castration.
