To model the cryobiological responses of cells and tissues, the cellular membrane permeability characteristics are often measured at suprazero temperatures as well as at subzero temperatures with and without the presence of extra-cellular ice. These measured membrane permeability characteristics are then used to predict the responses of cells and tissues for a given thermal insult with the ultimate aim of mitigating the damage caused during the freeze-thaw process. This brief review articles summarizes efforts from my research group over the past 15 years as related to cryobiology of mammalian ovarian tissue sections, i...

BACKGROUND: Controlled ovarian hyperstimulation (COH) followed by oocyte retrieval is a leading option for fertility preservation before chemotherapy, yet this procedure causes excessive serum levels of estradiol (E2), which are often detrimental for cancer patients. Aromatase inhibitors are often used in breast cancer patients during COH to prevent elevated levels of E2. OBJECTIVES: To describe our experience with COH for oocyte cryopreservation in non-breast cancer patients using aromatase inhibitors...

Ovarian tissue cryopreservation is, in most cases, the only fertility preservation option available for female patients soon to undergo gonadotoxic treatment. To date, cryopreservation of ovarian tissue has been carried out by both traditional slow freezing method and vitrification, but even with the best techniques, there is still a considerable loss of follicle viability. In this report, we investigated a stepped cryopreservation procedure which combines features of slow cooling and vitrification (hereafter called stepped vitrification)...

OBJECTIVE: This study aimed to explore the characteristics and circumstances of women who cryopreserved their oocytes for non-medical indications and their reasons for cryopreservation. BACKGROUND: Oocyte cryopreservation for non-medical reasons is becoming increasingly common. Little is known about women who freeze their oocytes in this context. METHODS: All women who had cryopreserved oocytes for non-medical indications at a large Australian fertility treatment centre from 1999 to 2014 were invited to complete an anonymous postal survey...

STUDY QUESTION: Can novel genetic candidates involved in follicle dormancy, activation and integrity be identified from transcriptomic profiles of isolated granulosa cells from human primordial and primary follicles? SUMMARY ANSWER: The granulosa cell compartment of the human primordial and primary follicle was extensively enriched in signal transducer and activator of transcription 3 (STAT3) and cAMP-response element binding protein (CREB) signalling, and several other putative signalling pathways that may also be mediators of follicle growth and development were identified...

Ovarian tissue is increasingly being collected from cancer patients and cryopreserved for fertility preservation. While the only available option to restore fertility is autologous transplantation, this treatment is not appropriate for all patients due to the risk of reintroducing cancer cells and causing disease recurrence. Harnessing the full reproductive potential of this tissue to restore fertility requires the development of culture systems that support oocyte development from the primordial follicle stage...

An improvement in the survival rates of cancer patients and recent advancements in assisted reproductive technologies have led to remarkable progress in oncofertility and fertility preservation treatments. Currently, for adults and postpubertal girls, oocyte or embryo cryopreservation is an established method. If their cancer treatment cannot be postponed for 2 weeks, ovarian tissue cryopreservation is offered as an experimental technique. For prepubertal girls, ovarian tissue cryopreservation is the only option...

Fertility preservation is routinely performed in cancerology but less systematically used in the field of immune diseases, even though the use of gonadotoxic treatments in young patients may be required and even though the disease itself can alter fertility. This review aimed to clarify the indications and methods of fertility preservation in this context. Cyclophosphamide is the only immunosuppressive drug requiring fertility preservation in women. In men, fertility preservation should be proposed before treatment with cyclophosphamide, methotrexate, mycophenolate mofetil or mTOR inhibitors...

PURPOSE: Even with 86 live births reported globally so far, the mechanism of primordial follicle loss following autotransplantation of the frozen-thawed ovarian tissue needs further evaluation. Pten, Tsc1, p27, and Amh are the inhibitor proteins that play crucial roles in suppressing the transition from the primordial follicle to primary state, maintaining the primordial follicle reserve. In this study, we aimed to evaluate whether the expression patterns of these proteins change and it may be related to the global primordial follicle loss after autotransplantation of the frozen-thawed ovarian tissue...

In vitro fertilization (IVF) and embryo cryopreservation have become increasingly common in recent years. As utilization increases, it is important to understand the clinical effects these technologies have on offspring, as well as the mechanisms behind these effects. Many epidemiologic studies have observed that pregnancies following IVF are more likely to be affected by obstetric complications such as pre-eclampsia, preterm birth, and small for gestational age neonates compared with naturally conceived pregnancies...

Platelets modulate clinically relevant yet incompletely understood tissue regeneration processes, and platelet rich plasma (PRP) has been previously used with some success in various non-reproductive medical contexts. Here, we extended PRP application to ovarian tissue with a view to document impact on ovarian reserve among women attending for infertility treatment. PRP was freshly isolated from patients (n= 4) with diminished ovarian reserve as determined by at least one prior IVF cycle canceled for poor follicular recruitment response or estimated by serum AMH and/or FSH, no menses for ≥1 year...

The aim of this study was to define the population, morphological and ultrastructural characteristics of bitch preantral follicles (PAFs) and to compare the effects on the morphology of PAF of two cryopreservation techniques - slow freezing (SF) and vitrification (V) - of bitches' ovarian tissue. The average population (number per ovary) of PAFs was 48,541 ± 18,366, where 94.25% were primordial (45,145 ± 16,076). The average diameter of the primordial follicles was 27.5 ± 4.2 μm. The overall percentage of morphologically normal PAFs was 93...

STUDY QUESTION: Is elevated late-follicular phase progesterone (EP) associated with a deleterious impact on embryo quality (EQ) and cumulative live birth rates (LBRs)? SUMMARY ANSWER: EP was associated with a decrease in embryo utilization and cumulative LBRs. WHAT IS KNOWN ALREADY: Ovarian stimulation promotes the production of progesterone (P) which adversely affects IVF pregnancy outcomes. However, evidence regarding a potential association between EP an EQ is lacking...

Given the age-related decline in ovarian reserve and oocyte quality, it is unsurprising the global trend of deferring motherhood has resulted in increased levels of involuntary childlessness. The development of oocyte vitrification, with pregnancy and livebirth rates now comparable to using fresh oocytes, has provided an opportunity to electively cryopreserve oocytes for future use, empowering women with the capacity to delay their childbearing years. Whilst it enhances reproductive autonomy, age-related obstetric complications, economic implications and the risk of unsuccessful future treatment make it a controversial therapeutic option...

The survival rate of vitrified-thawed ovarian tissues after autotransplantation still needs to be improved. Therefore finding an ideal cryoprectant to reduce the damage to ovaries that caused by vitrification will pave the way for application of ovary cryopreservation on clinics. Experiments were conducted to investigate the effect of sodium alginate in cryoprotectant solution on mouse ovaries during the vitrification process. The ovaries obtained from 6-weeks old CD1 were assigned into six groups from A to F...

We aimed to evaluate the effect of two vitrification methods on the morphology and functionality of vitrified feline preantral follicles. Feline ovarian tissue was vitrified with EG + trehalose combined or not with dimethyl sulphoxide (DMSO), using two different techniques (open or closed systems). Morphology, developmental capacity and mRNA expression of markers for follicle survival and quality were assessed before and after in vitro culture (IVC). Both vitrification and culture media were serum-free. Vitrification of feline ovarian tissue from five adult domestic cats was performed with EG + trehalose combined or not with DMSO...
