SummaryFertility preservation in women has become well established over the last two decades. Nevertheless, options for cancer survivors need to be improved to regain ovarian functioning, ideally leading to pregnancy and live birth. Techniques to protect the ovary from the damage of cytotoxic agents, to improve the survival of follicles in the ovarian graft, and to minimize the risk of re-seeding malignant cells after ovarian tissue transplantation are the object of current research all over the world. The demand for fertility preservation procedures in patients with benign diseases like systemic lupus erythematosus before cytotoxic therapy, in patients with endometriosis before surgery, and in patients with genetic predispositions which can lead to a premature ovarian failure will further increase in coming years. In this short review, these future perspectives are presented.

Abstract Study question What is the gap between guidance and practice of fertility preservation between countries and within countries with common clinical guidelines? Summary answer Substantial variation in provision of FP exists between countries and within individual countries with gaps between national and international guidelines and policies governing provision. What is known already A robust guideline on female FP was published by ESHRE in 2020, advising the application of FP in cancer and other conditions where treatment with cytotoxic agents or surgery will compromise reproductive function. Across Europe, in 13 countries (43.3%) FP is funded for all available FP procedures, in 13 countries (43.3%) no FP funding is available, and in 4 countries (13.3%) at least one FP option is funded. Variation in state provision of fertility care in different countries in Europe was highlighted in the ESHRE guidance. It did not specifically examine individual national policies or whether a national policy exists. Study design, size, duration Five clinicians performing FP in Europe were contacted to collect current FP provision data. Policies retrieved from the internet were not included as they could not be verified. Finally, FP funding policies for 135 Clinical Commissioning Groups (CCGs) in England, 14 Health Boards in Scotland, 7 Health Boards in Wales and 5 Trusts in Northern Ireland and 17 policies for regional heath services in Spain were included were included. Participants/materials, setting, methods Policies on FP for the UK and Spain were reviewed (n = 178), including policies from the 161 regions from the four nations of the UK and policies of 17 autonomous bodies in Spain. Information on funded procedures, type of conditions included for funding and duration of storage were extracted. The provision of FP was compared to the current European Society of Human Reproduction and Embryology (ESHRE) and National Institute for Health and Care Excellence (NICE) guidelines. Main results and the role of chance In England, 127/128 (99%) CCGs fund cryopreservation of oocytes, sperm and embryos. Cancer is the exclusive indication in 11%. Provision of FP for transgender individuals is specified in 28%, ovarian tissue cryopreservation is funded in 8% and storage funding varies from five to ten years. In Scotland, a national policy is applied. All 14 health boards equitably fund cryopreservation of oocytes, sperm, embryos and ovarian and testicular tissue. Funding is provided for cancer, medical conditions which may impair fertility and transgender individuals. Storage funding is based on a five yearly review until age 43 in women and 60 in men. In Wales and Northern Ireland, cryopreservation of oocytes, sperm and embryos is funded for people undergoing medical or surgical treatment that is likely to make them infertile, provision for transgender individuals is not specified and ovarian tissue cryopreservation is not funded. In Spain, all 17 Health Services fund cryopreservation of oocytes, sperm and embryos for patients whose fertility is at risk due to gonadotoxic treatments or other pathological processes. Ovarian tissue cryopreservation is funded in 94%, provision for transgender individuals is specified in 12%, and storage funding is available until the age of 50 in women and 55 in men. Limitations, reasons for caution Inability to retrieve fertility preservation policies for every country in Europe is a limitation, for which ongoing collaboration is sought. The variable nature of FP provision is likely to be multi-factorial; a lag in publication of guidelines and updated policies, ethical considerations and resource distribution may govern health policies. Wider implications of the findings: The study highlights that provision of FP not only varies between countries but is also inconsistent within the same country. It is clear that there is a gap between ideal, evidence-based practice and actual provision. Variation in policies limits uniform access to care for patients. Trial registration number Not applicable.

SummaryIn the present review, the main strategies of female fertility preservation are covered. Procedures of fertility preservation are necessary for women who suffer from diseases whose treatment requires the use of aggressive therapies, such as chemotherapy and radiotherapy. These kinds of therapy negatively influence the health of gametes and their progenitors. The most commonly used method of female fertility preservation is ovarian tissue cryopreservation, followed by the retransplantation of thawed tissue. Another approach to female fertility preservation that has been actively developed lately is the ovarian tissuein vitroculture. The principal methods, advantages and drawbacks of these two strategies are discussed in this article.

Ovarian tissue cryopreservation is the only feasible method for fertility preservation in prepubertal girls that will undergo gonadotoxic chemotherapy. To date, the only clinical use of cryopreserved tissue is by a later tissue retransplantation to the patient. Clinical challenges in fertility preservation of very young patients with cancer include time constraints that do not allow to retrieve the tissue for cryopreservation before starting chemotherapy and the preclusion of future ovarian tissue transplantation due to the risk of reintroduction of malignant cells in patients with systemic diseases. To overcome these two challenges, we investigated using an experimental model the feasibility of retrieving secondary follicles from ovaries of prepubertal mice after cyclophosphamide (CPA) treatment in increasing doses of 50, 75, and 100 mg/kg. The follicles were thereafter cultured and matured in vitro. The main outcomes included the efficiency of the method in terms of obtained matured oocytes and the safety of these potentially fertility preservative procedures in terms of analyses of oocyte competence regarding normality of the spindle and chromosome configurations. Our findings demonstrated that it was feasible to isolate and culture secondary follicles and to obtain mature oocytes from prepubertal mice ovaries recently treated with CPA. The efficiency of this method was highly demonstrated in the 100 mg/kg CPA group, with near 90% follicle survival rate after 12 days’ culture, similarly to control. Around 80% of the follicles met the criteria to put into maturation, and more than 40% of them achieved metaphase II, with normal spindle and chromosome configurations observed. Suboptimal results were obtained in the 50 and 75 mg/kg CPA groups. These paradoxical findings towards CPA dose might probably reflect a more difficult selection of damaged growing follicles from ovaries recently treated with lower doses of CPA and a hampered ability to identify and discard those with reduced viability for the culture.

Ovarian tissue cryopreservation (OTC) and transplantation of frozen/thawed ovarian tissue (OTT) are used for fertility preservation in girls and women. Here, we evaluated the hormonal characteristics of women with or without postmenopausal levels of FSH at the time of OTT to study differences and conditions that best support the initiation of ovarian function. A total of 74 women undergoing OTT (n = 51 with menopausal levels of FSH; n = 23 with premenopausal levels) were followed by measurements of FSH, LH, AMH, and oestradiol. Concentrations of FSH and LH returned to premenopausal levels after 20 weeks on average, with a concomitant increase in oestradiol. Despite resumption of ovarian activity, AMH concentrations were in most instances below the detection limit in the menopausal group, suggesting a low ovarian reserve. Despite a higher age in the premenopausal group, they more often experienced an AMH increase than the menopausal group, suggesting that conditions in the premenopausal ovary better sustain follicle survival, perhaps due to the higher concentrations of oestradiol. Collectively, this study highlights the need for improving follicle survival after OTT. Age and the amount of tissue transplanted are important factors that influence the ability to regain ovarian activity and levels of FSH may need to be downregulated and oestradiol increased prior to OTT.

Objectives: Despite new treatment options, some patients with systemic lupus erythematosus (SLE) need to be treated with the cytotoxic agent cyclophosphamide (CYC). Unlike malignant disease, there are no recommendations for ovarian protection in SLE. The clinical experience of the FertiPROTEKT network as well as recommendations after literature review will be presented in this paper. Methods: Retrospective analyses of counselling and treatment data from the FertiPROTEKT register with special respect to SLE patients under 40 years prior to planned CYC treatment. Results: A total of 2836 patients were advised prior to cytotoxic treatment in one of the FertiPROTEKT centres during January 2007 to November 2011. Of those, 68 patients (mean age 25 +/− 6.07years) were counselled for severe SLE. Only five women did not make use of a fertility preservation method. Sixty-three patients (92.6%) decided in favour of a fertility preservation method. The largest proportion (91.2%) opted for treatment with a GnRH analogue. Ovarian tissue removal for cryoconservation was performed in 16 patients (25%). Stimulation therapy for cryoconservation of fertilized egg cells was performed in three patients (4.4%). Conclusions: When counselling patients with SLE for fertility preservation one has to be aware of the disease-specific risks. According to the literature, a safe and effective option in SLE up to now has been the use of a GnRH analogue. Cryoconservation of ovarian tissue must still be seen as an experimental treatment, but as data on removal, cryoconservation, retransplantation and pregnancies are steadily rising, this presents a promising option for young SLE patients. Cryoconservation of oocytes must be very critically evaluated due to the need for a stimulation therapy and should only be performed after particular consideration of the individual risks.

Premature gonadal failure is a common problem in patients with systemic lupus erythematosus (SLE) when gonadotoxic therapies are applied. The preservation of gonadal function and fertility is of great importance to many predominantly young SLE patients. Some fertility preservation methods are well established and well known, whereas others are considered more cautiously. In particular, the cryopreservation of ovarian tissue is a rarely chosen fertility preservation option for SLE patients of (pre)fertile age. We report the first case of successful conception and pregnancy of an SLE patient after autotransplantation of cryopreserved ovarian tissue. A 26-year-old SLE patient decided to undergo cryopreservation of ovarian tissue when receiving cyclophosphamide for lupus nephritis. Tissue removal, preparation, cryopreservation and quality control was performed, as described, according to current state-of-the-art techniques. After 6 years of being in remission using azathioprine and belimumab, her ovarian tissue was autotransplanted because of premature ovarian failure, diagnosed at the age of 32, and a wish to conceive. She conceived spontaneously 8 months later, having a diamniotic-dichoriotic twin pregnancy. The children were born prematurely due to preterm premature rupture of membranes in the 32nd week of gestation; mother and children are doing very well 8 months later. We regard the procedure to be an option worth consideration for our predominantly young SLE patients.
