[PMID: 38654466 DOI: 10.1093/humupd/dmae009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Revised: 03/20/2024] [Indexed: 04/26/2024] Open
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 The outcome of planned oocyte cryopreservation (POC) is inversely related to the age at the time of oocyte cryopreservation commencing in the mid-30 s. We sought to evaluate whether the age of women undergoing POC has changed over the last decade. METHODS The study employed a retrospective, observational multicenter design. It included all women who had at least one POC cycle in two large private IVF units belonging to the same medical organization in Israel. The main outcome measure was age at the first cycle. Data on the total number of women each year and their age at the first cycle were recorded. RESULTS Between 2011 and the end of 2023, 4488 women underwent POC. The average age at the first retrieval was 36.2 years (± 2.4). In 2011, the average age was 38.3 years (± 2.6), which decreased to 35.4 years (± 2.5) in 2023. The trendline indicates a decline in the average age of 3.0 months per year (β = - 0.252, F = 301.8, p < 0.001). The proportion of women aged < 36 at their first POC cycle increased from 14% in 2011 to 54% in 2023. CONCLUSIONS The age at the time of POC has significantly declined over the past decade. This trend may potentially lead to higher overall birth rates from POC, though further research is needed to confirm this hypothesis.

[PMID: 38876980 PMCID: PMC11291942 DOI: 10.1093/humrep/deae121] [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: 11/18/2023] [Revised: 05/10/2024] [Indexed: 06/16/2024] Open
Abstract
STUDY QUESTION Does a purpose-designed Decision Aid for women considering elective egg freezing (EEF) impact decisional conflict and other decision-related outcomes? SUMMARY ANSWER The Decision Aid reduces decisional conflict, prepares women for decision-making, and does not cause distress. WHAT IS ALREADY KNOWN Elective egg-freezing decisions are complex, with 78% of women reporting high decisional conflict. Decision Aids are used to support complex health decisions. We developed an online Decision Aid for women considering EEF and demonstrated that it was acceptable and useful in Phase 1 testing. STUDY DESIGN, SIZE, DURATION A single-blind, two-arm parallel group randomized controlled trial was carried out. Target sample size was 286 participants. Randomization was 1:1 to the control (existing website information) or intervention (Decision Aid plus existing website information) group and stratified by Australian state/territory and prior IVF specialist consultation. Participants were recruited between September 2020 and March 2021 with outcomes recorded over 12 months. Data were collected using online surveys and data collection was completed in March 2022. PARTICIPANTS/MATERIALS, SETTING, METHODS Females aged ≥18 years, living in Australia, considering EEF, proficient in English, and with internet access were recruited using multiple methods including social media posts, Google advertising, newsletter/noticeboard posts, and fertility clinic promotion. After completing the baseline survey, participants were emailed their allocated website link(s). Follow-up surveys were sent at 6 and 12 months. Primary outcome was decisional conflict (Decisional Conflict Scale). Other outcomes included distress (Depression Anxiety and Stress Scale), knowledge about egg freezing and female age-related infertility (study-specific measure), whether a decision was made, preparedness to decide about egg freezing (Preparation for Decision-Making Scale), informed choice (Multi-Dimensional Measure of Informed Choice), and decision regret (Decision Regret Scale). MAIN RESULTS AND THE ROLE OF CHANCE Overall, 306 participants (mean age 30 years; SD: 5.2) were randomized (intervention n = 150, control n = 156). Decisional Conflict Scale scores were significantly lower at 12 months (mean score difference: -6.99 [95% CI: -12.96, -1.02], P = 0.022) for the intervention versus control group after adjusting for baseline decisional conflict. At 6 months, the intervention group felt significantly more prepared to decide about EEF than the control (mean score difference: 9.22 [95% CI: 2.35, 16.08], P = 0.009). At 12 months, no group differences were observed in distress (mean score difference: 0.61 [95% CI: -3.72, 4.93], P = 0.783), knowledge (mean score difference: 0.23 [95% CI: -0.21, 0.66], P = 0.309), or whether a decision was made (relative risk: 1.21 [95% CI: 0.90, 1.64], P = 0.212). No group differences were found in informed choice (relative risk: 1.00 [95% CI: 0.81, 1.25], P = 0.983) or decision regret (median score difference: -5.00 [95% CI: -15.30, 5.30], P = 0.337) amongst participants who had decided about EEF by 12 months (intervention n = 48, control n = 45). LIMITATIONS, REASONS FOR CAUTION Unknown participant uptake and potential sampling bias due to the recruitment methods used and restrictions caused by the coronavirus disease 2019 pandemic. Some outcomes had small sample sizes limiting the inferences made. The use of study-specific or adapted validated measures may impact the reliability of some results. WIDER IMPLICATIONS OF THE FINDINGS This is the first randomized controlled trial to evaluate a Decision Aid for EEF. The Decision Aid reduced decisional conflict and improved women's preparation for decision making. The tool will be made publicly available and can be tailored for international use. STUDY FUNDING/COMPETING INTEREST(S) The Decision Aid was developed with funding from the Royal Women's Hospital Foundation and McBain Family Trust. The study was funded by a National Health and Medical Research Council (NHMRC) Project Grant APP1163202, awarded to M. Hickey, M. Peate, R.J. Norman, and R. Hart (2019-2021).

Clinical outcomes of vitrified-warmed autologous oocyte cycles with 15-year follow-up at a single UK centre: consistent and predictable results. Reprod Biomed Online 2024:104376. [PMID: 39025683 DOI: 10.1016/j.rbmo.2024.104376] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2024] [Revised: 06/13/2024] [Accepted: 06/13/2024] [Indexed: 07/20/2024]
Abstract
RESEARCH QUESTION What were the clinical outcomes from 332 autologous vitrified- warmed oocyte cycles derived from 3182 elective autologous oocyte freeze cycles carried out between 2008 and 2022 in a single-centre series? DESIGN In this retrospective observational study, outcomes in 299 patients returning to use their frozen oocytes between 2015 and 2023 were analysed. RESULTS A total of 3328 elective oocyte vitrification cycles were performed in 2280 patients. The return rate to use oocytes was 14% (299/2171). Mean ages were 37.6 years at storage and 40 at warming. Ninety-three clinical pregnancies and 77 healthy live births were recorded. The live birth rate (LBR) was 24% (39/163) per fresh transfer and 17% (39/227) per embryo transferred. Stratified by age at freezing, the LBR per embryo transferred was 26% (12/47) in participants under 35 years, 20% (24/118) in those 35-39 years and 5% (3/62) in those 40+ years. Frozen embryo transfers (FET) achieved a 30% (24/80) LBR per embryo transfer and a 27% (24/90) LBR per embryo transferred. PGT-A for embryo selection doubled the LBR compared with FET from an untested embryo after one attempt (40% versus 21%). In patients aged over 40 years, the cumulative LBR reached 42% per patient in euploid FET. CONCLUSION The proportion of patients who returned to use their stored oocytes and the clinical outcomes were consistent with other recent reports and challenges the prevalent critical narrative regarding elective oocyte freezing for fertility preservation. The results are now comparable to routine IVF. Not everyone who returns to use their oocytes will conceive, but for those choosing to preserve their fertility, oocyte freezing can provide reproducible and reassuring results.

Abstract
PURPOSE To examine the effects of age, mature oocyte number, and cycle number on cumulative live birth rates after planned oocyte cryopreservation (OC), with the goal of developing a patient counselling tool. METHODS We performed a retrospective cohort study of all patients with ≥ 1 autologous oocyte thaw at our university-affiliated fertility center before 12/31/2023. Patients were included if they (1) had a live birth or ongoing pregnancy > 12 weeks from OC, or (2) used all oocytes and euploid/untested embryos from OC. Primary outcome was cumulative live birth / ongoing pregnancy rate (CLBR). RESULTS 527 patients with 1 OC cycle, 149 patients with 2 OC cycles, and 55 patients with ≥ 3 OC cycles were included. Overall CLBR was 43%. CLBR was > 70% among patients who thawed ≥ 20 mature oocytes that were cryopreserved at age < 38 years. Multiple logistic regression showed that age at first OC and total number of mature oocytes thawed independently predicted CLBR, but number of OC cycles did not. CONCLUSION Patients must be counselled that younger age at OC and more mature oocytes improve CLBR. However, additional OC cycles do not independently improve CLBR. Our results can help patients decide whether to pursue additional OC cycles to obtain more oocytes.

Abstract
RESEARCH QUESTION What happens to eggs after egg freezing? DESIGN A retrospective cohort study was performed spanning 2012-2022. Data were obtained from seven assisted reproductive technology clinics in Victoria, Australia. Aggregated, de-identified data were collected on cycles that resulted in egg freezing and the following outcomes, including treatment involving thawed eggs and disposition outcomes of surplus eggs. RESULTS The number of patients with eggs in storage grew rapidly from 144 in 2012 to 2015 in 2022. In 2022, 73% of patients had stored their eggs for <5 years, 25% for 5-10 years, and 2% for ≥10 years. Most thaw cycles (600/645, 93%) involved eggs that had been frozen for <5 years, of which 47% had been frozen for <6 months. Overall, the live birth rate per initiated thaw cycle was 12%. Across the study period, 2800 eggs from 286 patients were either discarded, donated or exported. Of the 128 patients who discarded their eggs, 32% had stored their eggs for <5 years, 32% for 5-10 years and 36% for >10 years. Of the 23 patients who donated their eggs to someone else, all but four had stored their eggs for <5 years. No eggs were donated to research over the study period. CONCLUSIONS This study shows that very few patients have made the decision to use or relinquish their eggs. Strategies may be needed to address the prolonged storage of surplus eggs, and ensure that patients are supported to make decisions regarding the fate of their eggs which align with their preferences and values.

Abstract
BACKGROUND Delayed pregnancy is a worldwide trend, especially in Western countries. University students and professors are at high risk of presenting age-related reproductive difficulties due to this new reproductive profile. Thus, through this study, we aimed at exploring the knowledge, awareness, and attitude of university students and professors related to fertility and fertility preservation (FP). METHODS We adopted a prospective cross-sectional study design and included students and professors from private university located in the Northeast of Brazil. Eligible participants (male and female) were invited through an online message. The participants accessed the online questionnaire through a link. RESULTS We performed 256 surveys (100 students and 156 professors). The overall mean age of participants was 35.8±13.1 years (from 18 to 67 years). Fertility was considered relevant by all participants, being very important among a greater number of students compared to professors, 61% versus 30.1%, P<0.001, respectively. The main reasons why participants could have postponed parenthood were reach financial stability (62.1%), career building (51.2%), health issues (37.9%), and not having a partner (33.9%). Students demonstrated a better understanding of FP and highlighted the importance of the age of females at the time of the oocyte cryopreservation. Very few students and professors already discussed reproductive planning with a health professional. CONCLUSIONS We observed a deficiency in the knowledge of Brazilian university students and professors about female fertility and FP options. Thus, exposing the population to information related to FP should be hyped in the university environment.

Abstract
OBJECTIVES The present study was designed to examine the attitudes towards oocyte cryopreservation among healthcare providers working in hospitals across specialties and potential influencing factors. DESIGN A cross-sectional study. SETTING The questionnaire was distributed among Chinese healthcare providers via the Credamo platform. PARTICIPANTS There were 877 respondents recruited from 8 April to 8 May 2022, among whom 160 were identified as unqualified because of inconsistency between the IP and work addresses. OUTCOME MEASURES Individual attitudes towards oocyte cryopreservation under four different settings, familiarity with oocyte cryopreservation and perceived risks about oocyte cryopreservation of healthcare providers were measured using a self-designed questionnaire. RESULTS There were 877 respondents recruited, and 717 were identified as qualified respondents. Two latent classes of healthcare providers characterised by different attitudes towards oocyte cryopreservation under four different settings were identified, the supportive and reluctant. Familiarity with oocyte cryopreservation had a significant direct effect on perceived risks, with better familiarity predicting lower perceived risks (β=-0.102, p<0.05). Perceived risks showed a significant direct effect on participants' attitudes towards oocyte cryopreservation, with higher perceived risks predicting a more reluctant attitude (β=0.165, p<0.001). CONCLUSIONS The majority of healthcare providers held a reluctant attitude towards oocyte cryopreservation of unmarried women for non-medical reasons, which might relate to their worries about the risks to offspring's health and lack of knowledge about a reproductive technique.

Abstract
Planned oocyte cryopreservation is an ethically permissible procedure that may help individuals avoid future infertility. Because planned oocyte cryopreservation is new and evolving, it is essential that those considering using it be informed about the uncertainties regarding its efficacy and long-term effects. This replaces the document of the same name, last published in 2017.

Abstract
Significant ethnic and racial disparities exist in the utilization and outcomes of assisted reproductive technology (ART) in the United States. The popularity of fertility preservation (FP) procedures, a specific application of ART for those desiring to delay childbearing, has increased; however, many minority populations have seen a less rapid uptake of these services. Minority patients pursuing ART are more likely to have poorer in vitro fertilization (IVF) and pregnancy outcomes. These outcomes are used to predict success after FP and may lessen the appeal of such procedures in these populations. Suboptimal outcomes are further compounded by challenges with receiving referrals to, accessing, and paying for FP services. Resolving these disparities in minority populations will require culturally appropriate education surrounding the benefits of ART and FP, the demonstration of favorable outcomes in ART and FP through continued research engaging minority participants, and continued advocacy for expanded access to care for patients.

Abstract
The 2022 White Paper on Singapore Women’s Development, which aimed at a fair and inclusive society where both women and men can pursue their aspirations fully, announced the option for elective egg freezing (EEF) and that the age limit for EEF was planned to be set at 35 years. The limit has been set at 37 years following recent review of success rates of EEF up to this age.2 This was implemented on 1 July 2023, presenting a conundrum among health professionals and women alike. While this is an exciting long-overdue progress in women’s reproductive autonomy, elective egg freezing needs adequate counselling and critical appraisal before a woman embarks on this journey. In this issue of the Annals, Ong et al.3 have presented a comprehensive overview on the key clinical aspects of EEF that a clinician should consider, while empowering women in this complicated decision-making. This review is a foundation for the consideration of EEF for young Singaporean women who intend to navigate newly charted waters in EEF in the context of a still rather conservative society.

Abstract
Introduction Female fecundity decreases significantly after the age of 32, and rapidly so after age 37. There is no treatment to prevent this decline. Furthermore, globally, women are getting married later and the age at which they have their first child is increasing. As of July 2023, elective egg freezing (EEF) or oocyte cryopreservation (OC) for age-related fertility decline, commenced in Singapore. With medical advancements in OC, EEF is no longer considered experimental. The aim of this review is to examine the existing literature around EEF with regard to reproductive outcomes and its safety, to better guide clinicians in counselling young single women. Method Published studies were examined to increase understanding on optimal age for EEF, ideal number of oocytes for a live birth, recommended OC protocols, cryopreservation techniques affecting thaw survival or fertilisation, oocyte storage and pregnancy risks. Results Models predict that EEF should be performed at age <37 years and to achieve a 70% chance of live birth, women would need 14, 15 and 26 mature oocytes at ages 30-34, 35-37 and >38 years, respec-tively. An antagonist stimulation protocol with an agonist trigger would minimise ovarian hyper-stimulation syndrome and duration of stimulation without affecting outcomes. Oocyte vitrification in comparison to slow freezing increases thaw survival, fertilisation and clinical pregnancy rates. No increased risks exist for the woman, future pregnancy or child when compared with conventional IVF. Conclusion EEF is a viable option for single women desiring fertility preservation. Financial costs are significant, but returns are worthwhile if oocytes are utilised.

Abstract
Although oocyte cryopreservation was initially used as a fertility preservation strategy for medical indications, it is now is increasingly used to circumvent age-related infertility. Outcomes following planned oocyte vitrification, also known as elective egg freezing, are limited. Current studies show higher success rates for individuals undergoing fertility preservation treatment under age 35. Additionally, while freezing 20 oocytes is optimal to achieve pregnancy, freezing at least 8-10 oocytes is recommended. While fertility is not guaranteed, current evidence demonstrates that planned oocyte vitrification is an overall safe, low risk method of fertility preservation to reduce the risk for age-related infertility.

Abstract
The objective of this review is to provide an update on planned oocyte cryopreservation. This fertility preservation method increases reproductive autonomy by allowing women to postpone childbearing whilst maintaining the option of having a biological child. Oocyte cryopreservation is no longer considered experimental, and its use has increased dramatically in recent years as more women delay childbearing for personal, professional and financial reasons. Despite increased usage, most patients who have undergone oocyte cryopreservation have not yet warmed their oocytes. Most women who cryopreserve oocytes wait years to use them, and many never use them. Studies have demonstrated that oocyte cryopreservation results in live birth rates comparable with IVF treatment using fresh oocytes, and does not pose additional safety risks to offspring. Based on current evidence, cryopreserving ≥20 mature oocytes at <38 years of age provides a 70% chance of one live birth. However, larger studies from a variety of geographic locations and centre types are needed to confirm these findings. Additional research is also needed to determine the recommended age for oocyte cryopreservation, recommended number of oocytes to cryopreserve, return and discard/non-use rates, cost-effectiveness, and how best to distribute accurate and up-to-date information to potential patients.

[PMID: 37678730 DOI: 10.1016/j.fertnstert.2023.08.972] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Revised: 08/31/2023] [Accepted: 08/31/2023] [Indexed: 09/09/2023]
Abstract
OBJECTIVE(S) The objectives of our study were to investigate the live birth rate (LBR) per oocyte retrieved during in vitro fertilization, in patients who had used all their embryos and to extrapolate the LBR in patients with remaining frozen embryos by calculating the expected LBR from these embryos. DESIGN A retrospective cohort study. SETTING A single academically affiliated fertility clinic. PATIENT(S) Autologous in vitro fertilization cycles from January 2014 to December 2020. Data on the number of oocytes retrieved, number of embryos obtained and transferred (at cleavage or blastocyst-stage), use of preimplantation genetic testing for aneuploidy (PGT-A), and number of live births were obtained. The expected LBR was estimated in patients with remaining frozen embryos according to nationally reported Society for Assisted Reproductive Technology LBR data. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Live birth rate per oocyte retrieved. RESULT(S) A total of 12,717 patients met the inclusion criteria and underwent a total of 20,677 oocyte retrievals which yielded a total of 248,004 oocytes and 57,268 embryos (fresh and frozen). In patients who had fully utilized all their embryos the LBR per oocyte was 2.82% (ranging from 11.3% aged <35 years to 1.2% aged >42 years). Stratification of the population based on PGT-A utilization yielded similar results (with PGT-A: 2.88% and without PGT-A: 2.79%). When stratified by the Society for Assisted Reproductive Technology age groups, the addition of PGT-A in patients aged 35-37 and 38-40 years yielded higher LBR per oocyte compared with patients who did not add PGT-A (P<.05). In patients with remaining frozen embryos who had added PGT-A, the projected LBR per oocyte was 8.34%. Use of PGT-A in patients aged <35 and 35-37 years decreased LBR per oocyte (P<.001 and P=.03, respectively) but improved LBR per oocyte in patients aged 38-40 and 41-42 years (P=.006 and P=.005, respectively). Poisson regression analysis demonstrated an age threshold of 38.5, below which PGT-A lowers LBR per oocyte compared with no PGT-A. CONCLUSION(S) Despite clinical and scientific advances in Assisted Reproductive Technology, with the current protocols of ovarian stimulation, the LBR per oocyte remains low reflecting a biological barrier that has yet to be overcome. Overall, the addition of PGT-A did not demonstrate improved outcomes.

Abstract
RESEARCH QUESTION What are the predictors of willingness to donate frozen oocytes among women of reproductive age in Australia? DESIGN An online survey involving 303 women of reproductive age (18-49 years) in Australia who had not frozen their oocytes or planned to freeze their oocytes in the next 12 months. The survey assessed demographic variables, prototype willingness model variables (attitude, subjective norm, prototype similarity and prototype favourability) and additional variables (altruism, empathy and infertility awareness) as predictors of hypothetical scenarios of willingness to donate frozen oocytes. A multivariate repeated measures analysis of variance explored differences in willingness to donate frozen oocytes. Hierarchical multiple regression analysis examined predictors of donor willingness. RESULTS Women's willingness to donate their frozen oocytes was higher for donating to a friend or family member and to research compared with an egg bank or fertility clinic, or a couple advertising online for an egg donor (all P < 0.001). The prototype willingness model variables were significant predictors of willingness to donate showing slightly varied patterns across four scenarios. After accounting for demographics, regression models including prototype willingness model variables and additional variables accounted for 45-64% of variance in donor willingness. CONCLUSIONS Frozen oocyte donation may be facilitated by improving attitudes towards donation and establishing positive images of donors. Professionals requiring frozen oocytes for research could focus on creating a sense of social approval for donating in this context. Encouraging frozen oocyte donation could increase access to oocytes for IVF treatment and aid in reducing the psychological burdens associated with involuntary childlessness.

Abstract
Cryopreservation has revolutionized the treatment of infertility and fertility preservation. This review summarizes the milestones that paved the way to the current routinary clinical implementation of this game-changing practice in assisted reproductive technology. Still, evidence to support "the best practice" in cryopreservation is controversial and several protocol adaptations exist that were described and compared here, such as cumulus-intact vs. cumulus-free oocyte cryopreservation, artificial collapse, assisted hatching, closed vs. open carriers, and others. A last matter of concern is whether cryostorage duration may impact oocyte/embryo competence, but the current body of evidence in this regard is reassuring. From social and clinical perspectives, oocyte and embryo cryopreservation has evolved from an afterthought when assisted reproduction was intended for immediate pregnancy with supernumerary embryos of secondary interest to its current purpose, which primarily is to preserve fertility long-term and more comprehensively allow for family planning. However, the initial consenting process, which still is geared to short-term fertility care, may no longer be relevant when the individuals that initially preserved the tissues have completed their reproductive journey. A more encompassing counseling model is required to address changing patient values over time.

F&S SCIENCE 2023; 4:185-192. [PMID: 37201752 DOI: 10.1016/j.xfss.2023.05.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/27/2023] [Revised: 05/10/2023] [Accepted: 05/10/2023] [Indexed: 05/20/2023]
Abstract
OBJECTIVE To assess whether co-culture with vitrified-warmed cumulus cells (CCs) in media drops improves rescue in vitro maturation (IVM) of previously vitrified immature oocytes. Previous studies have shown improved rescue IVM of fresh immature oocytes when cocultured with CCs in a three-dimensional matrix. However, the scheduling and workload of embryologists would benefit from a simpler IVM approach, particularly in the setting of time-sensitive oncofertility oocyte cryopreservation (OC) cases. Although the yield of developmentally competent mature metaphase II (MII) oocytes is increased when rescue IVM is performed before cryopreservation, it is unknown whether maturation of previously vitrified immature oocytes is improved after coculture with CCs in a simple system not involving a three-dimensional matrix. DESIGN Randomized controlled trial. SETTING Academic hospital. PATIENTS A total of 320 (160 germinal vesicles [GVs] and 160 metaphase I [MI]) immature oocytes and autologous CC clumps were vitrified from patients who were undergoing planned OC or intracytoplasmic sperm injection from July 2020 until September 2021. INTERVENTIONS On warming, the oocytes were randomized to culture in IVM media with CCs (+CC) or without CCs (-CC). Germinal vesicles and MI oocytes were cultured in 25 μL (SAGE IVM medium) for 32 hours and 20-22 hours, respectively. MAIN OUTCOME MEASURES Oocytes with a polar body (MII) were randomized to confocal microscopy for analysis of spindle integrity and chromosomal alignment to assess nuclear maturity or to parthenogenetic activation to assess cytoplasmic maturity. Wilcoxon rank sum tests for continuous variables and the chi square or Fisher's exact test for categorical variables assessed statistical significance. Relative risks (RRs) and 95% confidence intervals (CIs) were calculated. RESULTS Patient demographic characteristics were similar for both the GV and MI groups after randomization to +CC vs. -CC. No statistically significant differences were observed between +CC vs. -CC groups regarding the percentage of MII from either GV (42.5% [34/80] vs. 52.5% [42/80]; RR 0.81; 95% CI: 0.57-1.15]) or MI (76.3% [61/80]; vs. 72.5% [58/80]; RR 1.05; 95% CI: 0.88-1.26]) oocytes. An increased percentage of GV-matured MIIs underwent parthenogenetic activation in the +CC group (92.3% [12/13] vs. 70.8% [17/24]), but the difference was not statistically significant (RR 1.30; 95% CI: 0.97-1.75), whereas the activation rate was identical for MI-matured oocytes (74.3% [26/35] vs. 75.0% [18/24], CC+ vs. CC-; RR 0.99; 95% CI: 0.74-1.32). No significant differences were observed between +CC vs. -CC groups for cleavage of parthenotes from GV-matured oocytes (91.7% [11/12] vs. 82.4% [14/17]) or blastulation (0 for both) or for MI-matured oocytes (cleavage: 80.8% [21/26] vs. 94.4% [17/18]; blastulation: 0 [0/26] vs. 16.7% [3/18]). Further, no significant differences were observed between +CC vs. -CC for GV-matured oocytes regarding incidence of bipolar spindles (38.9% [7/18] vs. 33.3% [5/15]) or aligned chromosomes (22.2% [4/18] vs. 0.0 [0/15]); or for MI-matured oocytes (bipolar spindle: 38.9% [7/18] vs. 42.9% [2/28]); aligned chromosomes (35.3% [6/17] vs. 24.1% [7/29]). CONCLUSIONS Cumulus cell co-culture in this simple two-dimensional system does not improve rescue IVM of vitrified, warmed immature oocytes, at least by the markers assessed here. Further work is required to assess the efficacy of this system given its potential to provide flexibility in a busy, in vitro fertilization clinic.

Abstract
Fertility preservation in cancer patients is currently based on either assisted reproductive technology or fertility-sparing surgery. Loss of fertility may be caused by excisional surgery associated with an adnexal or uterine pathology or secondary to gonadal insufficiency caused by chemotherapy or radiation. The counseling of these patients is very important, being carried out jointly by the oncologist, gynecologist, and reproductive medicine specialist. Reproductive surgery usually requires avoiding laparotomy to significantly reduce the formation of adhesions and trauma or tissue damage. This is done using standard laparoscopic surgery or robotic surgery (computer-assisted laparoscopy), a method increasingly used and accessible to all specialists who want to maintain the fertility of their patients with various oncological diseases.

Abstract
Many people hope that the unused and unwanted eggs frozen by women for self-use could be applied to reduce the shortage of donor eggs. However, several practical (additional screening and counselling) and ethical (informed consent and reimbursement) issues may dampen this hope. This paper also considers the question of whether elective egg freezers who want to donate their eggs should be reimbursed for the costs they have met for the IVF cycle and storage. It is argued that a partial reimbursement for the collection (hormonal stimulation and retrieval) is morally acceptable because it is limited to proven expenses (and does not violate the altruism rule) and because the recipients should contribute to the costs of a scheme from which they are benefiting. The storage fee should be paid by the egg freezer herself and no reward for effort, time and inconvenience should be given. This compromise benefits both donors and recipients.

The purpose of this study is to evaluate the live birth outcome following oocyte thaw in women who underwent social egg freezing at Guy's Hospital, alongside a detailed published literature review to compare published results with the current study. A retrospective cohort study was conducted between January 2016 and March 2022 for all women who underwent egg freezing during this period. Overall, 167 women had 184 social egg freezing cycles. The mean age at freeze was 37.1 years and an average of 9.5 eggs were frozen per retrieval. In total, 16% of the women returned to use their frozen eggs. The mean egg thaw survival rate post egg thaw was 74%. The mean egg fertilisation rate was 67%. The pregnancy rate achieved per embryo transfer was 48% and the live birth rate per embryo transfer was 35%. We also noted that irrespective of age at freezing, a significantly high live birth rate was achieved when the number of eggs frozen per patient was 15 or more. Despite the rapid increase in social egg freezing cycles, the utilisation rate remains low. Pregnancy and live birth rate post thaw are encouraging if eggs are frozen at a younger age and if 15 eggs or more were frozen per patient.

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.

J Assist Reprod Genet 2023; 40:1281-1290. [PMID: 37058259 PMCID: PMC10310667 DOI: 10.1007/s10815-023-02789-w] [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: 02/13/2023] [Accepted: 03/24/2023] [Indexed: 04/15/2023] Open
Abstract
PURPOSE To (1) prospectively characterize the incidence of decision regret among women considering planned oocyte cryopreservation (planned OC), comparing those who pursued treatment vs those who did not freeze eggs, and (2) to identify baseline predictors for future decision regret. METHODS A total of 173 women seen in consultation for planned OC were followed prospectively. Surveys were administered at (1) baseline (< 1 week after initial consultation) and (2) follow-up, 6 months after planned OC among participants who froze eggs or 6 months following consultation in the absence of further communication to pursue treatment. The primary outcome was the incidence of moderate-to-severe decision regret, indicated by a Decision Regret Scale score > 25. We also examined predictors of regret. RESULTS The incidence of moderate-to-severe regret over the decision to freeze eggs was 9% compared to 51% over the decision not to pursue treatment. Among women who froze eggs, adequacy of information at baseline to decide about treatment (aOR 0.16, 95% CI 0.03, 0.87) and emphasis on future parenthood (aOR 0.80, 95% CI 0.66, 0.99) were associated with reduced odds of regret. Forty-six percent of women who froze eggs regretted not doing so earlier. Among women who did not freeze eggs, the primary reasons were financial and time constraints, correlating with increased odds of decision regret in an exploratory analysis. CONCLUSIONS Among women undergoing planned OC, the incidence of decision regret is low compared to the regret confronting women seen in consultation for planned OC but who do not pursue treatment. Provider counseling is key to offset the regret risk.

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.

Abstract
Upon legalization of social egg freezing in Singapore from 2023 onwards, compulsory pre-procedure counselling is mandated for all prospective patients to enable informed choice about whether to undergo the procedure. Being a newly introduced medical procedure in Singapore, there are currently no clear directives on what pre-procedure counselling for elective egg freezing should entail. Due to pervasive media and internet influences, prospective egg freezing patients could be misled into believing that the procedure represents a guaranteed path to future motherhood, contrary to statements by professional bodies such as the American Society for Reproductive Medicine (ASRM) and the British Fertility Society (BFS). Hence, comprehensive counselling is recommended to provide women with evidence-based information (e.g. success rates of social egg freezing for women of their age) to ensure they make informed decisions and to avoid possible decision regret. For this purpose, a systematic protocol and methodology for pre-procedure counselling of women considering elective egg freezing was developed, incorporating flowcharts and decision trees that are specifically tailored to the unique sociocultural values and legal restrictions in Singapore. Questions relating to the why, what, how, where and when of the egg freezing procedure should be addressed, which could serve as a roadmap to facilitate informed decision-making by women considering elective egg freezing.

Abstract
BACKGROUND Elective egg freezing decisions are complex. We developed a Decision Aid for elective egg freezing and conducted a phase 1 study to evaluate its acceptability and utility for decision-making. METHODS The online Decision Aid was developed according to International Patient Decision Aid Standards and evaluated using a pre/post survey design. Twenty-six Australian women aged 18-45 years, interested in receiving elective egg freezing information, proficient in English, and with access to the internet were recruited using social media and university newsletters. Main outcomes were: acceptability of the Decision Aid; feedback on the Decision Aid design and content; concern raised by the Decision Aid, and; utility of the Decision Aid as measured by scores on the Decisional Conflict Scale and on a study-specific scale assessing knowledge about egg freezing and age-related infertility. RESULTS Most participants found the Decision Aid acceptable (23/25), balanced (21/26), useful for explaining their options (23/26), and for reaching a decision (18/26). Almost all reported satisfaction with the Decision Aid (25/26) and the level of guidance it provided (25/26). No participant reported serious concerns about the Decision Aid, and most would recommend it to other women considering elective egg freezing (22/26). Median Decisional Conflict Scale score decreased from 65/100 (Interquartile range: 45-80) pre-Decision Aid to 7.5/100 (Interquartile range: 0-37.5) post-Decision Aid review (p < 0.001). Median knowledge score increased from 8.5/14 (Interquartile range: 7-11) pre-Decision Aid to 11/14 (Interquartile range: 10-12) post-Decision Aid review (p = 0.01). CONCLUSION This elective egg freezing Decision Aid appears acceptable and useful for decision-making. It improved knowledge, reduced decisional conflict and did not raise serious concerns. The Decision Aid will be further evaluated using a prospective randomised control trial. STUDY REGISTRATION ACTRN12618001685202 (retrospectively registered: 12 October 2018).

Abstract
OBJECTIVE To explore the factors that influence elective egg freezers' disposition decisions toward their surplus-frozen oocytes. DESIGN Qualitative. SETTING Not applicable. PATIENT(S) Thirty-one participants: 7 past; 6 current; and 18 future oocyte disposition decision-makers. INTERVENTION(S) Not applicable. MAIN OUTCOME MEASURE(S) Qualitative thematic analysis of interview transcripts. RESULTS Six inter-related themes were identified related to the decision-making process which are as follows: decisions are dynamic; triggers for the final decision; achieving motherhood; conceptualization of oocytes; the impacts of egg donation on others; and external factors affecting the final disposition outcome. All women reported a type of trigger event for making a final decision (e.g., completing their family). Women who achieved motherhood were more open to donating their oocytes to others but were concerned about the implications for their child and felt responsibility for potential donor children. Women who did not achieve motherhood were unlikely to donate to others due to the grief of not becoming a mother, often feeling alone, misunderstood, and unsupported. Reclaiming oocytes (e.g., taking them home) and closure ceremonies helped some women process their grief. Donating to research was viewed as an altruistic option as oocytes would not be wasted and did not have the "complication" of a genetically-linked child. There was a general lack of knowledge around disposition options at all stages of the process. CONCLUSION(S) Oocyte disposition decisions are dynamic and complex for women, exacerbated by a general lack of understanding of these options. The final decision is framed by: whether women achieved motherhood, dealing with grief if they did not achieve motherhood, and considering the complexities of donating to others. Additional decision support through counseling, decision aids, and early consideration of disposition when eggs are initially stored may help women make informed decisions.

Abstract
Ovarian tissue has a unique microarchitecture and a complex cellular and molecular dynamics that are essential for follicular survival and development. Due to this great complexity, several factors may lead to ovarian insufficiency, and therefore to systemic metabolic disorders and female infertility. Techniques currently used in the reproductive clinic such as oocyte cryopreservation or even ovarian tissue transplant, although effective, have several limitations, which impair their wide application. In this scenario, mimetic ovarian tissue reconstruction comes as an innovative alternative to develop new methodologies for germ cells preservation and ovarian functions restoration. The ovarian extracellular matrix (ECM) is crucial for oocyte viability maintenance, once it acts actively in folliculogenesis. One of the key components of ovarian bioengineering is biomaterials application that mimics ECM and provides conditions for cell anchorage, proliferation, and differentiation. Therefore, this review aims at describing ovarian tissue engineering approaches and listing the main limitations of current methods for preservation and reestablishment of ovarian fertility. In addition, we describe the main elements that structure this study field, highlighting the main advances and the challenges to overcome to develop innovative methodologies to be applied in reproductive medicine. Impact Statement This review presents the main advances in the application of tissue bioengineering in the ovarian tissue reconstruction to develop innovative solutions for ovarian fertility reestablishment.

Abstract
Purpose This study aims to investigate the prevalence of inherited thrombophilia in women with recurrent pregnancy loss during the first trimester of pregnancy. The study was assessed the potential role of inherited thrombophilia in recurrent miscarriages and evaluate the consequences of this condition on the reproductive outcomes of affected women. Material and Methods This study was an analytical descriptive carried out in Khartoum, Sudan. The research comprised 98 controls who had given birth twice or more without experiencing a miscarriage and 120 patients. Each patient had done more than two miscarriages especially when the pregnancy is at its beginning trimester. (APCR), and (PS) were investigated using the clotting approach. There was an assessment of biological activities of (ATIII), (PC), and (PS) for both groups using the chromogenic method. Results The average age of the patients was 34, which was higher than the average age of the controls (33.5). The patient group had a much higher rate of multiple miscarriages among the women.: 35 (29.17%), 45 (37.50%), and 40 (33.33%). The incidence of PC deficiencies was determined to be 1.02% (1/98), whereas neither ATIII nor PS deficiencies were seen in the control group (0/98). APCR was more prevalent in the control group (4.10% or 4/98). Conclusion Despite contradicting evidence to the contrary in the literature, our findings imply that most miscarriages occur when pregnancy is at the first trimester when a woman is pregnant and they are all caused by thrombophilia.

Abstract
The ability to understand whether embryos survive the thaw process is crucial to transferring competent embryos that can lead to pregnancy. The objective of this study was to develop a proof of concept deep learning model capable of assisting embryologist assessment of survival of thawed blastocysts prior to embryo transfer. A deep learning model was developed using 652 labeled time-lapse videos of freeze-thaw blastocysts. The model was evaluated against and along embryologists on a test set of 99 freeze-thaw blastocysts, using images obtained at 0.5 h increments from 0 to 3 h post-thaw. The model achieved AUCs of 0.869 (95% CI 0.789, 0.934) and 0.807 (95% CI 0.717, 0.886) and the embryologists achieved average AUCs of 0.829 (95% CI 0.747, 0.896) and 0.850 (95% CI 0.773, 0.908) at 2 h and 3 h, respectively. Combining embryologist predictions with model predictions resulted in a significant increase in AUC of 0.051 (95% CI 0.021, 0.083) at 2 h, and an equivalent increase in AUC of 0.010 (95% CI -0.018, 0.037) at 3 h. This study suggests that a deep learning model can predict in vitro blastocyst survival after thaw in aneuploid embryos. After correlation with clinical outcomes of transferred embryos, this model may help embryologists ascertain which embryos may have failed to survive the thaw process and increase the likelihood of pregnancy by preventing the transfer of non-viable embryos.

JOURNAL OF OBSTETRICS AND GYNAECOLOGY CANADA 2022; 44:1271-1278. [PMID: 36272695 DOI: 10.1016/j.jogc.2022.10.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Revised: 10/04/2022] [Accepted: 10/05/2022] [Indexed: 11/05/2022]
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
PURPOSE To report outcome of planned oocyte cryopreservation (POC) in the first 8 years of this treatment in our center. METHODS A retrospective study in a university-affiliated medical center. RESULTS A total of 446 women underwent POC during 2011-2018. Fifty-seven (13%) women presented to use these oocytes during the study period (until June 2021). POC was performed at a mean age of 37.9 ± 2.0 (range 33-41). Age at thawing was 43.3 ± 2.1 (range 38-49). A total of 34 (60%) women transferred their oocytes for thawing at other units. Oocyte survival after thawing was significantly higher at our center than following shipping to ancillary sites (78 vs. 63%, p = 0.047). Forty-nine women completed their treatment, either depleting their cryopreserved oocytes without conceiving (36) or attaining a live birth (13)-27% live birth rate per woman. Only one of eleven women who cryopreserved oocytes aged 40 and older had a live birth using thawed oocytes. CONCLUSION Women should be advised to complete planned oocyte cryopreservation before age 40, given low success rates in women who underwent cryopreservation at advanced reproductive age. In this study, oocyte shipping was associated with lower survival rate. These findings may be relevant for women considering POC and utilization of cryopreserved oocytes.

A SART data cost-effectiveness analysis of planned oocyte cryopreservation versus in vitro fertilization with preimplantation genetic testing for aneuploidy considering ideal family size. Fertil Steril 2022; 118:875-884. [PMID: 36175208 PMCID: PMC9613595 DOI: 10.1016/j.fertnstert.2022.07.022] [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: 04/13/2022] [Revised: 07/16/2022] [Accepted: 07/20/2022] [Indexed: 01/13/2023]
Abstract
OBJECTIVE To determine the cost-effectiveness of planned oocyte cryopreservation (OC) as a strategy for delayed childbearing to achieve 1 or 2 live births (LB) compared with in vitro fertilization (IVF) and preimplantation genetic testing for aneuploidy (PGT-A) at advanced reproductive age. DESIGN Decision tree model with sensitivity analyses using data from the Society for Assisted Reproductive Technology Clinical Outcome Reporting System and other clinical sources. SETTING Not applicable. PATIENT(S) A data-driven simulated cohort of patients desiring delayed childbearing with an ideal family size of 1 or 2 LB. INTERVENTION(S) Not applicable. MAIN OUTCOME MEASURE(S) Probability of achieving ≥1 or 2 LB, average and maximum cost per patient, cost per percentage point increase in chance of LB, and population-level cost/LB. RESULT(S) For those desiring 1 LB, planned OC at age 33 with warming at age 43 decreased the average total cost per patient from $62,308 to $30,333 and increased the likelihood of LB from 50% to 73% when compared with no OC with up to 3 cycles of IVF/PGT-A at age 43. For those desiring 2 LB, 2 cycles of OC at age 33 and warming at age 40 yielded the lowest cost per patient and highest likelihood of achieving 2 LB ($51,250 and 77%, respectively) when compared withpursuing only 1 cycle of OC ($75,373 and 61%, respectively), no OC and IVF/PGT-A with embryo banking ($79,728 and 48%, respectively), or no OC and IVF/PGT-A without embryo banking ($79,057 and 19%, respectively). Sensitivity analyses showed that OC remained cost-effective across a wide range of ages at cryopreservation. For 1 LB, OC achieved the highest likelihood of success when pursued before age 32 and remained more effective than IVF/PGT-A when pursued before age 39, and for 2 LB, 2 cycles of OC achieved the highest likelihood of success when pursued before age 31 and remained more effective than IVF/PGT-A when pursued before age 39. CONCLUSION(S) Among patients planning to postpone childbearing, OC is cost-effective and increases the odds of achieving 1 or 2 LB when compared with IVF/PGT-A at a more advanced reproductive age.

Reprod Biol Endocrinol 2022; 20:123.

Abstract
BACKGROUND The previous model-based cost-effectiveness analyses regarding elective oocyte cryopreservation remained debatable, while the usage rate may influence the cost per live birth. The aim of this study is to disclose the usage and cost-effectiveness of the planned cryopreserved oocytes after oocyte thawing in real-world situations. METHODS This was a retrospective single-center observational study. Women who electively cryopreserved oocytes and returned to thaw the oocytes were categorized as thawed group. The oocytes were fertilized at our center and the sperm samples for each individual was retrieved from their respective husbands. Clinical outcomes were traced and the cumulative live birth rate per thawed case was calculated. The costs from oocyte freezing cycles to oocyte thawing, and embryo transfer cycles were accordingly estimated. The cumulative cost per live birth was defined by the cumulative cost divided by the live births per thawed case. RESULTS We recruited 645 women with 840 oocyte retrieval cycles for elective oocyte freezing from November 2002 to December 2020. The overall usage rate was 8.4% (54/645). After the storage duration exceeded ten years, the probabilities of thawing oocytes were 10.6%, 26.6%, and 12.7% from women who cryopreserved their oocytes at the age ≤ 35 years, 36-39 years, and ≥ 40 years, respectively (P = 0.304). Among women who thawed their oocytes, 31.5% (17/54) of women achieved at least one live birth. For the age groups of ≤ 35 years, 36-39 years, and ≥ 40 years, the cumulative live birth rates per thawed case were 63.6%, 42.3%, and 17.6%, respectively (P = 0.045), and the cumulative costs for one live birth were $11,704, $17,189, and $35,642, respectively (P < 0.001). CONCLUSIONS The overall usage rate was 8.4% in our cohort. The cumulative live birth rate was greatest in the youngest group and the cumulative cost per live birth was highest in the oldest group, which was threefold greater than that in the group aged ≤ 35 years. The findings added to the limited evidence of the usage rate in real-world situations, which could hopefully aid future analysis and decision-making in public health policy and for women willing to preserve fertility. TRIAL REGISTRATION None.

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
PURPOSE To characterize the frozen oocyte disposition preferences of patients undergoing medical and planned fertility preservation. METHODS All oocyte cryopreservation (OC) patients were identified between 2015 and 2018. Demographic information and fertility preservation (FP) indication (medical or planned) were identified for each patient. Oocyte disposition options included disposal, donation to research, or donation to a specified third party, which was decided at the time of initial consent and made available in the electronic medical record. The primary outcome was the disposition selection. Secondary outcomes included differences in demographic variables and disposition selections between medical and planned FP patients using chi-squared analysis. RESULTS A total of 336 OC patients with a documented oocyte disposition preference were identified in the study timeframe. Patients were on average 34.5 years old (SD = 5.1) and were predominantly White (70.2%), nulliparous (83.0%), with a BMI of 24.7 (SD = 5.4). A total of 101 patients underwent OC for medical FP and 235 for planned FP. In both groups, the most commonly selected disposition option was donation to research (50% planned, 52% medical), followed by donation to a specified third party (30% planned, 30% medical), and finally disposal of oocytes (20% planned, 18% medical). There were no significant differences in disposition selection between each group. When comparing patient variables between groups, medical FP patients were more likely to be under the age of 35 and were less likely to be nulliparous (p < .001). CONCLUSION This study shows that oocyte disposition choices are similar in patients undergoing OC for medical and planned indications. As donation to research was the most commonly selected option in both groups, it is time to start thinking of streamlining ways to utilize this potential research material in the future.

Abstract
OBJECTIVE To review the outcomes of patients who underwent autologous oocyte thaw after planned oocyte cryopreservation. DESIGN Retrospective cohort study. SETTING Large urban university-affiliated fertility center. PATIENT(S) All patients who underwent ≥1 autologous oocyte thaw before December 31, 2020. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) The primary outcome was the final live birth rate (FLBR) per patient, and only patients who had a live birth (LB) or consumed all remaining inventory (cryopreserved oocytes and resultant euploid/untested/no result embryos) were included. The secondary outcomes were laboratory outcomes and LB rates per transfer. RESULT(S) A total of 543 patients underwent 800 oocyte cryopreservations, 605 thaws, and 436 transfers. The median age at the first cryopreservation was 38.3 years. The median time between the first cryopreservation and thaw was 4.2 years. The median numbers of oocytes and metaphase II oocytes (M2s) thawed per patient were 14 and 12, respectively. Overall survival of all thawed oocytes was 79%. Of all patients, 61% underwent ≥1 transfer. Among euploid (n = 262) and nonbiopsied (n = 158) transfers, the LB rates per transfer were 55% and 31%, respectively. The FLBR per patient was 39%. Age at cryopreservation and the number of M2s thawed were predictive of LB; the FLBR per patient was >50% for patients aged <38 years at cryopreservation or who thawed ≥20 M2s. A total of 173 patients (32%) have remaining inventory. CONCLUSION(S) Autologous oocyte thaw resulted in a 39% FLBR per patient, which is comparable with age-matched in vitro fertilization outcomes. Studies with larger cohorts are necessary.

Abstract
The 2021 Women's Preventive Services Initiative Well-Woman Chart outlines a framework for incorporating preventive health services recommended by the Women's Preventive Services Initiative, the US Preventive Services Task Force, and Bright Futures based on age, health status, and risk factors. Following the previous guidelines for preventive care, this document failed to offer recommendations or guidelines for infertility screening and fertility counseling in the course of well-woman care. Healthcare providers may be less likely to address fertility with their patients in the absence of clear, evidence-based recommendations, potentially resulting in underinformed reproductive choices and compromised reproductive potential. Given the devastating consequences of infertility and unintended childlessness, we, herein, propose that infertility screening and fertility counseling should become an integral part of well-woman care and that organizations, such as the Women's Preventive Services Initiative, put forth guidelines to assist providers in addressing fertility throughout a woman's reproductive lifespan.

Abstract
The use of planned oocyte cryopreservation for nonmedical need has been steadily increasing, especially since the experimental label on this procedure was lifted nearly 10 years ago. With this rise, patients' desires to postpone or conserve their reproductive potential have become increasingly nuanced, and the need for complex individualized counseling has grown. In addition, there are several ethical considerations, including risks, access, and patient comprehension that must be discussed with patients who are considering this procedure. In this review, we provide an in-depth discussion of these concepts, highlighting the need for individualized and comprehensive counseling that recognizes the gaps in knowledge that remains in this somewhat novel domain.

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.

WOMEN'S HEALTH (LONDON, ENGLAND) 2022; 18:17455057221139673. [PMID: 36448651 PMCID: PMC9720825 DOI: 10.1177/17455057221139673] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/04/2022] [Revised: 10/18/2022] [Accepted: 11/01/2022] [Indexed: 12/05/2022]
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. REGISTRATION DETAILS ACTRN12620001032943: Comparing different information resources on the process and quality of decision-making in women considering elective egg freezing.

Front Endocrinol (Lausanne) 2022; 13:873508. [PMID: 35685214 PMCID: PMC9171925 DOI: 10.3389/fendo.2022.873508] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Accepted: 04/07/2022] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND The opportunity for fertility preservation in adolescent and young adult (AYA) transmen is growing. Many AYA transmen desire future biologic children and are interested in ways to preserve fertility through oocyte cryopreservation prior to full gender affirmation, yet utilization of oocyte cryopreservation remains low. Additionally, standard practice guidelines currently do not exist for the provision of oocyte cryopreservation to AYA transmen. Our objective was to review our experience with oocyte cryopreservation in adolescent and young adult transmen in order to synthesize lessons regarding referral patterns, utilization, and oocyte cryopreservation outcomes as well as best practices to establish treatment guidance. METHODS This is a case series of all AYA transmen (aged 10 to 25 years) who contacted, consulted or underwent oocyte cryopreservation at a single high volume New York City based academic fertility center between 2009 and 2021. RESULTS Forty-four adolescent and young adult transmen made contact to the fertility center over the study period. Eighty percent (35/44) had a consultation with a Reproductive and Endocrinology specialist, with a median age of 16 years (range 10 to 24 years) at consultation. The majority were testosterone-naive (71%, 25/35), and had not pursued gender affirming surgery (86%, 30/35). Expedited initiation of testosterone remained the most commonly cited goal (86%, 30/35). Fifty-seven percent (20/35) pursued oocyte cryopreservation. Ninety-five percent (19/20) underwent successful transvaginal oocyte aspiration, with a median of 22 oocytes retrieved and 15 mature oocytes cryopreserved. There were no significant adverse events. At time of review, no patient has returned to utilize their cryopreserved oocytes. CONCLUSIONS Oocyte cryopreservation is a safe fertility preservation option in AYA transmen and is an important aspect of providing comprehensive transgender care. Insights from referral patterns, utilization, and oocyte cryopreservation outcomes from a single center's experience with adolescent and young adult transmen can be integrated to identify lessons learned with the goal of providing transparency surrounding the oocyte cryopreservation process, improving the education and comfort of patients and providers with fertility preservation, and easing the decision to pursue an oocyte cryopreservation cycle in parallel to gender-affirmatory care.

[PMID: 34452749 DOI: 10.1016/j.fertnstert.2021.07.1195] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2021] [Revised: 07/11/2021] [Accepted: 07/12/2021] [Indexed: 10/20/2022]
Abstract
OBJECTIVE To examine the disposition outcomes and disposition intentions of elective egg freezers (EEFs) toward their surplus frozen oocytes and the psychosocial determinants underlying these. DESIGN A systematic review and meta-analysis. SETTING Not applicable. PATIENT(S) Actual EEFs (women with oocytes in storage), potential EEFs (women investigating elective oocyte cryopreservation or about to freeze their oocytes), and women of reproductive age (women in the community aged ≥18 years). INTERVENTION(S) A systematic review was undertaken and electronically searched MEDLINE, Embase, and PsycINFO on the Ovid platform for conference abstracts and peer-reviewed articles, published in English after January 1, 2010. A search strategy combined synonyms for oocyte, cryopreservation, donation, disposition, elective, and attitude. Eligible studies assessed disposition outcomes (how an oocyte was disposed of) and disposition intentions (how women intend to dispose of an oocyte) and/or the psychosocial determinants underlying disposition outcomes and intentions. The Joanna Briggs Institute Prevalence Tool was used to assess the risk of bias. A meta-analysis using random effects was applied to pool proportions of women with similar disposition intentions toward their oocytes. MAIN OUTCOME MEASURE(S) Disposition outcomes and intentions toward surplus frozen oocytes: donate to research; donate to others; discard; unsure. Psychosocial determinants (beliefs, attitudes, barriers, and facilitators) of disposition outcomes and intentions. RESULT(S) A total of 3,560 records were identified, of which 22 (17 studies) met the inclusion criteria (8 studies from Europe, 7 from North America, and 2 from Asia). No studies reported on past oocyte disposition outcomes. Seventeen studies reported on the future disposition intentions of 5,446 women. Only 2 of the 17 studies reported on the psychosocial determinants of oocyte disposition intentions. There was substantial heterogeneity in the pooled results, which was likely a result of the significant variation in methodology. Actual EEFs were included in eight studies (n = 873), of whom 53% (95% confidence interval [CI], 44-63; I2, 87%) would donate surplus oocytes to research, 31% (95% CI, 23-40; I2, 72%) were unsure, 26% (95% CI, 17-38; I2, 92%) would donate to others, and 12% (95% CI, 6-21; I2, 88%) would discard their eggs. Psychosocial determinants: One study reported that 50% of these women were aware of friends and/or family having difficulty conceiving, which may have contributed to their willingness to donate to others. Potential EEFs were included in 4 studies (n = 645), of whom 38% (95% CI, 28-50; I2, 84%) would donate to research, 32% (95% CI, 17-51; I2, 91%) would donate to others, 29% (95% CI, 17-44; I2, 89%) would discard, and 7% (95% CI, 1-27; I2, 77%) were unsure. Psychosocial determinants: No studies. Women of reproductive age were included in 5 studies (n = 3,933), of whom 59% (95% CI, 48-70; I2, 97%) would donate to research and 46% (95% CI, 35-57; I2, 98%) would donate to others. "Unsure" and "discard" were not provided as response options. Psychosocial determinants: One study reported that the facilitators for donation to others included a family member or friend in need, to help others create a family, financial gain, to further science, and control or input over the selection of recipients. Barriers for donation included fear of having a biological child they do not know or who is raised by someone they know. CONCLUSION(S) No studies reported on the disposition outcomes of past EEFs. Disposition intentions varied across the three groups; however, "donating to research" was the most common disposition preference. Notably, the second disposition preference for one-third of actual EEFs was "unsure" and for one-third of potential EEFs was "donate to others." There were limited studies for actual and potential EEFs, and only two studies that explored the psychosocial determinants of oocyte disposition intentions. Additionally, these data suggest that disposition decisions change as women progress on their egg freezing journey, highlighting the importance of ongoing contact with the fertility team as intentions may change over time. More research is needed to understand the psychosocial determinants of oocyte disposition decisions so fertility clinics can provide EEFs with the support and information they need to make informed decisions about their stored eggs and reduce the level of uncertainty reported among EEFs and the potential risk of psychological distress and regret.

Abstract
Oocyte cryopreservation is a boon for women undergoing assisted reproductive technology. With the evolution in the technique of cryopreservation over the last three decades, there has been an exponential rise in the number of oocyte cryopreservation cycles for diverse indications. Apart from cancer patients, it has also been promoted as a mode of fertility insurance to overcome the age-related decline in fertility as well as post-surgical decline following endometriosis surgery. The objective of the review is to evaluate its clinical applications, ideal age at freezing, optimal oocyte number, freezing method of choice, efficacy, safety and recent advances. In the last decade, vitrification has surpassed slow freezing for oocyte cryopreservation. Although closed system of vitrification provides the aseptic environment, open vitrification is commonly followed in practice. Early to mid-thirties is a reasonable age group for planned oocyte cryopreservation, although it might be recommended at a younger age, in patients with diminished ovarian reserve. The patients should be motivated to preserve around 14–20 mature oocytes for successful live birth. Various studies have shown comparable fertilisation and pregnancy rates between Intracytoplasmic sperm injection with fresh and frozen-thawed oocytes. The available evidence has shown no increase in the incidence of congenital abnormalities in babies born through vitrified oocytes. In the future, image analysis using artificial intelligence, and spindle visualisation using poloscope may further enhance the outcome of oocyte cryopreservation.
