Abstract
BACKGROUND Awareness of the age-related decline in fertility potential has increased the popularity of planned oocyte cryopreservation (POC). However, data regarding outcomes of POC, including rates of women returning to thaw oocytes, as well as pregnancy and live birth rates, are scarce and based mostly on small case series. OBJECTIVE AND RATIONALE POC was defined as cryopreservation exclusively for prevention of future age-related fertility loss. The primary outcome was live birth rate per patient. The secondary outcomes included the return to thaw rate and laboratory outcomes. A meta-regression analysis examining the association between live birth and age above 40 or below 35 was conducted. SEARCH METHODS We conducted a systematic database search from inception to August 2022. The search included PubMed (MEDLINE) and EMBASE. Our search strategies employed a combination of index terms (Mesh) and free text words to compile relevant concepts. The systematic review and meta-regression were undertaken following registration of systematic review (PROSPERO registration number CRD42022361791) and were reported following guidelines of Preferred Reporting Items for Systematic Review and Meta-Analyses 2020 (PRISMA 2020). OUTCOMES The database search yielded 3847 records. After the selection process, 10 studies, conducted from 1999 to 2020, were included. Overall, 8750 women underwent POC, with a mean cryopreservation age of 37.2 (±0.8). Of those, 1517 women returned to use their oocytes with a return rate of 11.1% (± 4.7%). The mean age at the time of cryopreservation for women who returned to use their oocytes was 38.1 (±0.4), with an average of 12.6 (±3.6) cryopreserved oocytes per woman. In a meta-analysis, the oocyte survival rate was 78.5% with a 95% CI of 0.74-0.83 (I2 = 93%). The live birth rate per patient was 28% with a 95% CI of 0.24-0.33 (I2 = 92%). Overall, 447 live births were reported. In a sub-group analysis, women who underwent cryopreservation at age ≥40 achieved a live birth rate per patient of 19% (95% CI 0.13-0.29, I2 = 6%), while women aged ≤35 years old or younger had a higher live birth rate per patient of 52% (95% CI 0.41-0.63, I2 = 7%). WIDER IMPLICATIONS POC emerges as a feasible option for women aiming to improve their chances of conceiving at a later reproductive age. Nonetheless, it must be acknowledged that the overall success rates of POC are limited and that the likelihood of successful live birth declines as the age at cryopreservation rises. With increasing interest in POC, the collation of comprehensive and high-quality data is imperative to clearly define the outcomes for various age groups. REGISTRATION NUMBER CRD42022361791.

Abstract
PURPOSE Identifying the information and decision support needs of women interested in receiving planned oocyte cryopreservation (POC) information. METHODS An online survey of Australian women, aged 18-45, interested in receiving POC information, proficient in English, with internet access. The survey covered POC information sources, information delivery preferences, POC and age-related infertility knowledge (study-specific scale), Decisional Conflict Scale (DCS), and time spent considering POC. Target sample size (n=120) was determined using a precision-based method. RESULTS Of 332 participants, 249 (75%) had considered POC, whilst 83 (25%) had not. Over half (54%) had searched for POC information. Fertility clinic websites were predominately used (70%). Most (73%) believed women should receive POC information between ages 19-30 years. Preferred information providers were fertility specialists (85%) and primary care physicians (81%). Other methods rated most useful to deliver POC information were online. Mean knowledge score was 8.9/14 (SD:2.3). For participants who had considered POC, mean DCS score was 57.1/100 (SD:27.2) and 78% had high decisional conflict (score >37.5). In regression, lower DCS scores were associated with every 1-point increase in knowledge score (-2.4; 95% CI [-3.9, -0.8]), consulting an IVF specialist (-17.5; [-28.0, -7.1]), and making a POC decision (-18.4; [-27.5, -9.3]). Median time to decision was 24-months (IQR: 12.0-36.0) (n=53). CONCLUSION Women interested in receiving POC information had knowledge gaps, and wanted to be informed about the option by age 30 years from healthcare professionals and online resources. Most women who considered using POC had high decisional conflict indicating a need for decision support.

Abstract
Oocyte cryopreservation (OC) is the process in which ovarian follicles are stimulated, the follicular fluid is retrieved, and mature oocytes are isolated and vitrified. Since the first successful pregnancy utilizing previously cryopreserved oocytes in 1986, OC has become increasingly utilized as an option for future biologic children in patients facing gonadotoxic therapies, such as for the treatment of cancer. Planned OC, also termed elective OC, is growing in popularity as a means to circumvent age-related fertility decline. In this narrative review, we describe both medically indicated and planned OC, focusing on the physiology of ovarian follicular loss, OC technique and risks, timing of when OC should be performed, associated financial considerations, and outcomes.

Cost-effectiveness analysis of ovarian function preservation with GnRH agonist during chemotherapy in premenopausal women with early breast cancer. Hum Reprod 2023:7131352. [PMID: 37075316 DOI: 10.1093/humrep/dead073] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Revised: 03/25/2023] [Indexed: 04/21/2023] Open
Abstract
STUDY QUESTION Is it economically worthwhile to use GnRH agonist (GnRHa) to prevent menopausal symptoms (MS) and protect fertility in premenopausal women with breast cancer (BC) during chemotherapy from the US perspective? SUMMARY ANSWER It is cost-effective to administer GnRHa during chemotherapy in order to forefend MS in premenopausal patients with BC when the willingness-to-pay (WTP) threshold is $50 000.00 per quality-adjusted life-year (QALY), and to preserve fertility in young patients with BC who undergo oocyte cryopreservation (OC), or no OC, when the WTP thresholds per live birth are $71 333.33 and $61 920.00, respectively. WHAT IS KNOWN ALREADY Chemotherapy often results in premature ovarian insufficiency (POI) in premenopausal survivors of BC, causing MS and infertility. Administering GnRHa during chemotherapy has been recommended for ovarian function preservation by international guidelines. STUDY DESIGN, SIZE, DURATION Two decision-analytic models were developed, respectively, for preventing MS and protecting fertility over a 5-year period, which compared the cost-effectiveness of two strategies: adding GnRHa during chemotherapy (GnRHa plus Chemo) or chemotherapy alone (Chemo). PARTICIPANTS/MATERIALS, SETTING, METHODS The participants were early premenopausal women with BC aged 18-49 years who were undergoing chemotherapy. Two decision tree models were constructed: one for MS prevention and one for fertility protection from the US perspective. All data were obtained from published literature and official websites. The models' primary outcomes included QALYs and incremental cost-effectiveness ratios (ICERs). The robustness of the models was tested by sensitivity analyses. MAIN RESULTS AND THE ROLE OF CHANCE In the MS model, GnRHa plus Chemo resulted in an ICER of $17 900.85 per QALY compared with Chemo, which was greater than the WTP threshold of $50 000.00 per QALY; therefore, GnRHa plus Chemo was a cost-effective strategy for premenopausal women with BC in the USA. Probabilistic sensitivity analysis (PSA) results showed an 81.76% probability of cost-effectiveness in the strategy. In the fertility model, adding GnRHa for patients undergoing OC and those who were unable to undergo OC resulted in ICERs of $67 933.50 and $60 209.00 per live birth in the USA, respectively. PSA indicated that GnRHa plus Chemo was more likely to be cost-effective over Chemo when the WTP for an additional live birth exceed $71 333.33 in Context I (adding GnRHa to preserve fertility in young patients with BC after OC) and $61 920.00 in Context II (adding GnRHa to preserve fertility in young patients with BC who cannot accept OC). LIMITATIONS, REASONS FOR CAUTION The indirect costs, such as disease-related mental impairment and non-medical costs (e.g. transportation cost) were not included. All data were derived from previously published literature and databases, which might yield some differences from the real world. In addition, the POI-induced MS with a lower prevalence and the specific strategy of chemotherapy were not considered in the MS model, and the 5-year time horizon for having a child might not be suitable for all patients in the fertility model. WIDER IMPLICATIONS OF THE FINDINGS When considering the economic burden of cancer survivors, the results of this study provide an evidence-based reference for clinical decision-making, showing that it is worthwhile to employ GnRHa during chemotherapy to prevent MS and preserve fertility.

Abstract
OBJECTIVE Oocyte cryopreservation (OC) has increased in recent years; however, there is a paucity of published data on the use of cryopreserved oocytes and associated outcomes. METHODS A retrospective review of 748 OC cycles between 2013 and 2022 at a private fertility centre was performed. Outcome parameters for oocyte retrieval cycles were reviewed. For patients who returned for oocyte disposition, outcomes subsequent to oocyte re-warming, fertilization, and transfer were analyzed. RESULTS There were 748 OC cycles (653 elective and 95 non-elective) in 646 patients (556 elective and 90 non-elective). Patients were older at the time of freezing in the elective oocyte group compared with the non-elective group (36.5 vs. 28.8 y; P < 0.001). Sixty-five patients returned to warm and fertilize their oocytes (50 in the elective group and 15 in the non-elective group). The survival rate for warmed oocytes was 76.1% (541/711), and 66.2% of surviving oocytes were successfully fertilized, and 39.1% reached blastulation. Twenty-three patients underwent embryo transfers (10 after preimplantation genetic testing for aneuploidy), with 15 patients having at least 1 delivery or ongoing pregnancy. CONCLUSIONS To date, this is the largest published experience with OC in Canada. OC can lead to successful live births but does not guarantee a viable outcome for all patients. In this study, most patients with vitrified oocytes had not returned for disposition, so long-term follow-up is still required to verify the efficacy of OC.

Abstract
BACKGROUND Uptake of elective egg freezing has increased globally. The decision to freeze eggs is complex, and detailed, unbiased information is needed. To address this, we developed an online Decision Aid for women considering elective egg freezing. Decision Aids are the standard of care to support complex health decisions. OBJECTIVES This study will measure the impact of the Decision Aid on decision-making (e.g. decisional conflict, engagement in decision-making, distress, and decision delay) and decision quality (e.g. knowledge, level of informed choice, and regret). METHODS AND ANALYSIS A single-blinded two-arm parallel-group randomized controlled trial. Women considering elective egg freezing will be recruited using social media, newsletters, and fertility clinics. Data will be collected at baseline (recruitment), 6-month, and 12-month post-randomization. The primary hypothesis is that the intervention (Decision Aid plus Victorian Assisted Reproductive Technology Authority website) will reduce decisional conflict (measured using the Decisional Conflict Scale) at 12 months more than control (Victorian Assisted Reproductive Technology Authority website only). Secondary outcomes include engagement in decision-making (Perceived Involvement in Care Scale), distress (Depression, Anxiety, and Stress Scale), decision delay, knowledge, informed choice (Multi-dimensional Measure of Informed Choice), and decisional regret (Decisional Regret Scale). ETHICS The study was approved by the University of Melbourne Human Research Ethics Committee (Ethics ID: 2056457). Informed consent will be obtained from all participants prior to enrolment. DISCUSSION This is the first international randomized controlled trial that aims to investigate the effect of an elective egg freezing Decision Aid on decision-related outcomes (e.g. decisional conflict, informed choice, and regret). It is anticipated that participants who receive the Decision Aid will have better decision and health outcomes.

Abstract
The aim was to explain the factors that affect the decision-making processes of women considering oocyte cryopreservation. In this study, a web page was scanned between March and April 2020 that was appropriate to the "Evaluation of the Quality and Content of Websites Form." As a result, 4 main themes (unknown process, financial burden, social stigma, and future concerns) were created from the experiences of 23 women. The majority of women feel anxiety associated with the oocyte cryopreservation process. It is recommended that reliable information should be presented to society by health care professionals.

Abstract
Background: Oocyte cryopreservation opens up opportunities for women to preserve fertility when it is necessary to postpone pregnancy. After the advent of vitrification, the results of oocyte cryopreservation were significantly improved compared to conventional slow-freezing. Through these improvements, oocyte cryopreservation was introduced to overcome a decline in fecundity due to an increase in age, and this modality is defined as planned oocyte cryopreservation.Current Concepts: Oocytes cryopreserved through vitrification appear to result in similar clinical pregnancy rates and live birth rates compared to fresh oocytes, though the evidence is still limited. It has been reported that the live birth rate increases when the planned oocyte cryopreservation is performed at a younger age. Obstetrical and neonatal outcomes appear similar between vitrified and fresh oocytes.Discussion and Conclusion: Preliminary data supports planned oocyte cryopreservation as a feasible modality resulting in fertility preservation and subsequent live births. The fact that performing the procedure at a younger age can increase the oocyte yield, oocyte efficacy, and live birth rate can be discussed along with patient consultation. However, as there is still a lack of data on the standardized live birth rate, the number of oocytes to be collected, and the long-term effect on the children; more well-designed studies are needed to improve counseling and decision-making in patients seeking this treatment.

Abstract
BACKGROUND The utilization of oocyte cryopreservation (OC) has become popularized with increasing numbers of reproductive-aged patients desiring to maintain fertility for future family building. OC was initially used for fertility preservation in postmenarchal patients prior to gonadotoxic therapies; however, it is now available to patients to circumvent age-related infertility and other diagnoses associated with early loss of ovarian reserve. The primary aim of this paper is to provide a narrative review of the most recent and robust data on the utilization and outcomes of OC in both patient populations. OC results in similar oocyte yield in patients facing gonadotoxic therapies and patients undergoing planned OC. Available data are insufficient to predict the live birth rates or the number of oocytes needed to result in live birth. However, oocyte yield and live birth rates are best among patients < 37.5 years old or with anti-mullerian hormone levels > 1.995 ng/dL, at the time of oocyte retrieval. There is a high 'no use' rate (58.9%) in patients using planned OC with 62.5% returning to use frozen oocytes with a spouse. The utilization rate in medical OC patients is < 10%. There is currently no data on the effects of BMI, smoking, or ethnicity on planned OC outcomes. CONCLUSION It is too early to draw any final conclusions on outcomes of OC in medical OC and planned OC; however, preliminary data supports that utilization of OC in both groups result in preservation of fertility and subsequent live births in patients who return to use their cryopreserved eggs. Higher oocyte yield, with fewer ovarian stimulation cycles, and higher live birth rates are seen in patients who seek OC at younger ages, reinforcing the importance of age on fertility preservation. More studies are needed in medical OC and planned OC to help guide counseling and decision-making in patients seeking these services.
