Abstract
Background: The primary objective was to measure adherence to clinical practice guideline (CPG) recommendations for fertility preservation (FP) in pediatric cancer patients treated in National Cancer Institute Community Oncology Research Program (NCORP) sites. Secondary objectives were to describe factors such as site size associated with CPG-inconsistent care delivery and cryopreservation completion. Methods: This retrospective, multicenter study included patients 15 to 21 years old with a first cancer diagnosis from January 2014 through December 2015 who were previously enrolled to a Children's Oncology Group (COG) study and received care at a participating NCORP site. Patients were randomly selected from a list generated by the COG for chart review by participating sites. Primary outcome was care delivery that was inconsistent with a strong CPG recommendation on FP, namely discussion and offering of FP options before cancer treatment initiation, as adjudicated centrally by a panel. Results: A total of 129 patients from 25 sites were included. Among these, 48% (62/129) received CPG-inconsistent care. Most CPG-inconsistent care was due to lack of FP discussion documentation (93.5%, 58/62). Small site size, treatment at a pediatric (vs mixed adult/pediatric) site, and female sex were associated with higher odds of CPG-inconsistent care delivery. Conclusions: Newly diagnosed pediatric cancer patients often received CPG-inconsistent care for FP, with disproportionate gaps noted for females, and those treated at smaller or pediatric NCORP sites. The primary reason for CPG-inconsistent care is lack of FP discussion from clinicians. Opportunities to improve FP CPG implementation are highlighted.

Development and evaluation of a usable blastocyst predictive model using the biomechanical properties of human oocytes. PLoS One 2024; 19:e0299602. [PMID: 38696439 PMCID: PMC11065297 DOI: 10.1371/journal.pone.0299602] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Accepted: 02/13/2024] [Indexed: 05/04/2024] Open
Abstract
PURPOSE The purposes of this study were to determine whether biomechanical properties of mature oocytes could predict usable blastocyst formation better than morphological information or maternal factors, and to demonstrate the safety of the aspiration measurement procedure used to determine the biomechanical properties of oocytes. METHODS A prospective split cohort study was conducted with patients from two IVF clinics who underwent in vitro fertilization. Each patient's oocytes were randomly divided into a measurement group and a control group. The aspiration depth into a micropipette was measured, and the biomechanical properties were derived. Oocyte fertilization, day 3 morphology, and blastocyst development were observed and compared between measured and unmeasured cohorts. A predictive classifier was trained to predict usable blastocyst formation and compared to the predictions of four experienced embryologists. RESULTS 68 patients and their corresponding 1252 oocytes were included in the study. In the safety analyses, there was no significant difference between the cohorts for fertilization, while the day 3 and 5 embryo development were not negatively affected. Four embryologists predicted usable blastocyst development based on oocyte morphology with an average accuracy of 44% while the predictive classifier achieved an accuracy of 71%. Retaining the variables necessary for normal fertilization, only data from successfully fertilized oocytes were used, resulting in a classifier an accuracy of 81%. CONCLUSIONS To date, there is no standard guideline or technique to aid in the selection of oocytes that have a higher likelihood of developing into usable blastocysts, which are chosen for transfer or vitrification. This study provides a comprehensive workflow of extracting biomechanical properties and building a predictive classifier using these properties to predict mature oocytes' developmental potential. The classifier has greater accuracy in predicting the formation of usable blastocysts than the predictions provided by morphological information or maternal factors. The measurement procedure did not negatively affect embryo culture outcomes. While further analysis is necessary, this study shows the potential of using biomechanical properties of oocytes to predict embryo developmental outcomes.

Abstract
PURPOSE What are the reproductive outcomes of women who had fertility preservation (FP) using either oocyte or embryo vitrification after fertility-sparing surgery (FSS) for a borderline ovarian tumor (BOT)? METHODS A retrospective, single-center cohort study was conducted between January 2013 and December 2021. Patients with BOT who resorted to FP by vitrifying oocytes or embryos were included. Both clinical and reproductive parameters were reviewed. The primary outcome was live birth. RESULTS In total, thirteen patients who performed 31 FP cycles were included. Of those, six patients achieved eight live births after a mean follow-up period of 79 months. Three further pregnancies are still ongoing. All pregnancies/live births were obtained without using their cryopreserved oocytes or embryos. CONCLUSION Women who had FSS for BOT have favorable prospects of live offspring, even without the need to use their cryopreserved material. Fertility preservation in patients with BOT has to be considered as a tool to mitigate the risk of infertility that may arise in case of BOT recurrence requiring castrating surgery.

Abstract
PURPOSE Currently, 15% of gynaecological and 9% of haematological malignancies are diagnosed before the age of 40. The increased survival rates of cancer patients who are candidates for gonadotoxic treatments, the delay in childbearing to older ages, and the optimization of in vitro fertilisation techniques have all contributed to an increased interest in fertility preservation (FP) treatments. This study reviews the experience of the Fertility Preservation Programme (FPP) of a tertiary public hospital with a multidisciplinary approach. METHODS This retrospective study included all the available (FP) treatments, performed in patients of childbearing age between 2006 and 2022. RESULTS 1556 patients were referred to the FPP: 332 oocyte vitrification cycles, 115 ovarian cortex cryopreservation with 11 orthotopic autotransplantations, 175 gonadotropin-releasing hormone (GnRH) agonist treatments, 109 fertility-sparing treatments for gynaecological cancer, and 576 sperm cryopreservation were performed. Malignancy was the main indication for FP (the main indications being breast cancer in women and haematological malignancies in men), although non-oncological pathologies, such as endometriosis and autoimmune diseases, have increased in recent years. Currently, the most widely used FP technique is oocyte vitrification, the increase of which has been associated with a decrease in the use of cortex CP and GnRH agonists. CONCLUSIONS The increase in FP treatment reflects the implementation of reproductive counselling in oncology programmes. A multidisciplinary approach in a tertiary public hospital allows individualised FP treatment for each patient. In recent years, there has been a change in trend with the introduction of new indications for FP and a change in techniques due to their optimisation.

The Effect of Open and Closed Oocyte Vitrification Systems on Embryo Development: A Systematic Review and Network Meta-Analysis. J Clin Med 2024; 13:2651. [PMID: 38731179 PMCID: PMC11084263 DOI: 10.3390/jcm13092651] [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: 03/18/2024] [Revised: 04/03/2024] [Accepted: 04/27/2024] [Indexed: 05/13/2024] Open
Abstract
Background/Objectives: Open and closed vitrification systems are commonly employed in oocyte cryopreservation; however, there is limited evidence regarding a comparison of their separate impact on oocyte competence. This study uniquely brings to the literature, data on the effect of open versus closed vitrification systems on laboratory and clinical outcomes, and the effect of cooling and warming rates. Methods: A systematic search of the literature was performed using the databases PubMed/MEDLINE and the Cochrane Central Library, limited to articles published in English up to January 2023. A network meta-analysis was conducted comparing each vitrification system versus fresh oocytes. Results: Twenty-three studies were included. When compared to fresh oocytes, both vitrification devices resulted in lower fertilization rates per MII oocyte retrieved. When comparing the two systems in terms of survival rates, no statistically significant difference was observed. However, interestingly open systems resulted in lower cleavage and blastocyst formation rates per 2 pronuclear (2PN) oocyte compared to fresh controls, while at the same time no statistically significant difference was detected when comparing closed devices with fresh oocytes. Conclusions: In conclusion, closed vitrification systems appear to exert a less detrimental impact on the oocytes' competence, which is reflected in the blastocyst formation rates. Proof of superiority of one system versus the other may lead to standardization, helping to ultimately determine optimal practice in oocyte vitrification.

Abstract
Purpose Controversy exists on whether or not elective oocyte cryopreservation (eOC) can be conducted in public hospitals in China. Policymakers should take into account the benefits and risks in the Chinese population. This study explored basic data concerning the awareness, attitudes of eOC, and fertility desire of eOC in China to offer evidence for policy making. Methods A total of 442 people in four areas of China responded to a survey. The questionnaire was divided into three parts: awareness, attitude, and fertility desire of eOC. Descriptive analysis and multivariable regression analysis were used in the study. Results Generally, the respondents had a positive or neutral attitude towards eOC. However, about 90% of respondents did not know the cost of eOC. In general, a more positive attitude was found towards eOC among participants who had heard of the procedure compared with those who had not. Most women did not desire to reproduce by eOC. After adjusting for access to information, we found that female, older age groups, and singles were more likely to have increased awareness than their counterparts. The awareness of participants who accessed information from any source had a higher relative probability of having good awareness levels compared to participants who had not accessed the information. Undergraduates exhibited significantly higher levels of cognitive understanding, as indicated by their increased familiarity and comprehension, compared to high school students (relative risk ratio = 1.44, confidence interval = 0.48,4.29). Conclusion Continued discussion is needed regarding the ethical, legal, and social aspects of performing eOC in public hospitals. Furthermore, policies are needed to regulate eOC to protect the reproductive freedom of healthy women.

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
PURPOSE This study investigated the safety and effectiveness of oocyte vitrification by comparing the clinical pregnancy and perinatal outcomes between transfer cycles of vitrified oocytes and those of vitrified embryos. METHODS A retrospective cohort study was conducted to analyze the clinical data of patients who underwent cleavage-stage embryo transfer at the Department of Reproductive Medicine between January 2011 and June 2021. Seventy-seven transfer cycles of fresh cleavage-stage embryos developed from vitrified-thawed oocytes (oocyte vitrification group) and 2170 transfer cycles of vitrified-thawed cleavage-stage embryos developed from fresh oocytes (embryo vitrification group) were included. Further, 293 cases were selected from the embryo vitrification group after applying propensity score matching at 1:4. The primary outcomes were miscarriage rate, live birth rate, and neonatal birth weight. RESULTS No statistically significant differences were observed in the baseline data, pregnancy, perinatal outcomes, or neonatal outcomes for either singleton or twin births between the two groups after matching. Backwards stepwise regression was used to analyze the length of gestation. The age of female participants (β = - 0.410, 95% CI = - 1.339 ~ - 0.620, P < 0.001) had a statistically significant effect. CONCLUSION Oocyte vitrification results in similar clinical pregnancy and perinatal outcomes as does embryo vitrification; hence, it is a relatively safe assisted reproductive technique.

Abstract
Egg freezing can allow women to preserve their eggs to avoid age-related infertility. The UK's recent extension of elective egg freezing storage has been welcomed as a way of enhancing the reproductive choices of young women who wish to delay having children. In this paper, I explore the issue of enhancing women's reproductive choices, questioning whether there is a more significant aspect overlooked in egg freezing. While increasing storage limits expands reproductive choices for some women, focus on this extension alone, I argue, misses a fundamental issue with egg preservation that often remains ignored; the importance of effective information on egg freezing and the effect this has on women's reproductive choices. Ultimately, I highlight the crucial role of balanced information in enhancing women's choices regarding egg freezing and argue that focusing on extending and increasing provision may obscure this real opportunity to empower women and their authentic reproductive choices.

[PMID: 38508627 PMCID: PMC10952915 DOI: 10.1136/bmjopen-2023-076680] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Accepted: 03/06/2024] [Indexed: 03/22/2024] Open
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.

Is there a preferred time interval between gonadotropin-releasing hormone (GnRH) agonist trigger and oocyte retrieval in GnRH antagonist cycles? A retrospective cohort of planned fertility preservation cycles. J Assist Reprod Genet 2024:10.1007/s10815-024-03083-z. [PMID: 38492156 DOI: 10.1007/s10815-024-03083-z] [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: 12/12/2023] [Accepted: 03/04/2024] [Indexed: 03/18/2024] Open
Abstract
BACKGROUND The ideal time frame between gonadotropin-releasing hormone (GnRH) agonist (GnRHa) trigger administration and oocyte retrieval in GnRH antagonist cycles has not been well studied. Our goal was to evaluate the effect of this time interval on oocyte yield and oocyte maturation rate in GnRH antagonist cycles designated for non-medical ("planned") oocyte cryopreservation. METHODS We conducted a retrospective cohort study including patients who underwent elective fertility preservation, using the GnRH antagonist protocol and exclusively triggered by GnRH-agonist. We focused on the effect of the trigger-to-retrieval time interval on oocyte yield and maturation rate, while also incorporating age, body mass index (BMI), anti-Müllerian hormone (AMH) levels, basal Follicle-Stimulating Hormone (FSH) levels, as well as the type and dosage of gonadotropin FSH medication. RESULTS 438 cycles were included. Trigger-to-retrieval time interval ranged from 32.03 to 39.92 h. The mean oocyte yield showed no statistically significant difference when comparing retrievals < 36 h (n = 240, 11.86 ± 8.6) to those triggered at ≥ 36 h (n = 198, 12.24 ± 7.73) (P = 0.6). Upon dividing the cohort into four-time quartiles, no significant differences in the number of retrieved oocytes were observed (P = 0.54). Multivariate regression analysis failed to reveal any significant associations between the interval and the aforementioned variables. CONCLUSIONS The GnRHa trigger to oocyte retrieval interval range in our cohort did not significantly affect oocyte yield and maturation rate.

Abstract
Adolescent and young adult (AYA) oncology patients are unique in many aspects of their care; fertility preservation (FP) is one of the most complex to address. In addition to the newly diagnosed AYA patient, there are growing numbers of AYA survivors of childhood cancer who present with concerns about their fertility. Emerging independence, emotional and intellectual growth, and development of an adult mindset are hallmarks of the AYA population; these transitions heighten the intrinsic medical, social, and financial challenges of a cancer diagnosis. FP is extraordinarily important in AYA oncology and can be addressed in many ways: experimental options as well as standard of care, with key differences on the basis of pubertal development, cancer diagnosis, and urgency of cancer-directed therapy. Options exist both at diagnosis and throughout the survivorship journey. It is imperative that oncologists recognize the challenges in this age group, as well as opportunities to pursue FP. The field has evolved significantly in the past 25 years and will continue to evolve as we incorporate more immune-based and targeted therapies into our treatment regimens. This case-based review will explore opportunities to preserve fertility in this unique patient population.

J Clin Med 2024; 13:1060.

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
PURPOSE To describe recall of fertility-related consultations and cryopreservation and to examine reproductive goals and reproduction post-treatment in long-term survivors of adolescent and young adult (AYA) (age, 18-39 years) cancer. METHODS This study included n = 1457 male and n = 2112 female long-term survivors (Mage = 43-45 years; 5-22 years from diagnosis) who provided self-report. Clinical data were supplied by the Netherlands Cancer Registry. RESULTS Most male survivors (72.7%) recalled fertility-related consultations and 22.6% completed sperm cryopreservation. Younger age (OR = 2.8; 95%CI [2.2-3.6]), not having children (OR = 5.0; 95%CI [3.2-7.7]), testicular cancer or lymphoma/leukemia (OR = 2.8/2.5 relative to "others"), and more intense treatments (OR = 1.5; 95%CI [1.1-2.0]) were associated with higher cryopreservation rates. Time since diagnosis had no effect. Of men who cryopreserved, 12.1% utilized assisted reproductive technologies (ART). Most men (88.5%) felt their diagnosis did not affect their reproductive goals, but 7.6% wanted no (additional) children due to cancer. Half of female survivors (55.4%; n = 1171) recalled fertility-related consultations. Rates of cryopreservation were very low (3.6%), but increased after 2013 when oocyte cryopreservation became non-experimental. Of women who cryopreserved, 13.2% successfully utilized ART. Most women (74.8%) experienced no effects of cancer on reproductive goals, but 17.8% wanted no (additional) children due to cancer. CONCLUSIONS Cryopreservation in men varied by patient/clinical factors and was very low in women, but data of more recently treated females are needed. Utilizing cryopreserved material through ART was rare, which questions its cost-effectiveness, but it may enhance survivors' well-being. IMPLICATIONS FOR CANCER SURVIVORS The extent to which cryopreservation positively affects survivors' well-being remains to be tested. Moreover, effects of cancer on reproductive goals require further attention, especially in women who refrain from having children due to cancer.

A 10-year follow-up of reproductive outcomes in women attempting motherhood after elective oocyte cryopreservation. Hum Reprod 2024; 39:355-363. [PMID: 38145619 DOI: 10.1093/humrep/dead267] [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: 05/28/2023] [Revised: 12/05/2023] [Indexed: 12/27/2023] Open
Abstract
STUDY QUESTION Which reproductive treatment outcomes are observed in women who underwent elective oocyte cryopreservation (EOC) and who returned to the clinic with a desire for a child? SUMMARY ANSWER Whether to warm oocytes or to first use fresh own oocytes for ART depends on age upon returning, but both strategies result in favorable reproductive outcomes. WHAT IS KNOWN ALREADY Most affluent countries have observed a trend toward postponement of childbearing, and EOC is increasingly used based on the assumption that oocytes cryopreserved at a younger age may extend a woman's reproductive lifespan and mitigate her age-related fertility decline. Although most follow-up studies after EOC have focused on women who requested oocyte warming, a substantial proportion of women who do not conceive naturally will embark on fertility treatment without using their cryopreserved oocytes. Reports on reproductive outcomes in past EOC users are scarce, and the lack of reproductive treatment algorithms in this group of women hampers counseling toward the most efficient clinical strategy. STUDY DESIGN, SIZE, DURATION This retrospective observational single-center study encompasses 843 women who had elective oocyte vitrification between 2009 and 2019 at our fertility clinic. Women who underwent fertility preservation for medical or oncological reasons were excluded. This study describes the outcomes of the diverse reproductive treatment strategies performed until May 2022 in women returning to our clinic to attempt motherhood. PARTICIPANTS/MATERIALS, SETTING, METHODS Using descriptive statistics, patient characteristics and data of ovarian stimulation (OS) of EOC cycles were analyzed, as well as data related to OS and laboratory data of ART in women who pursued fertility treatment with and/or without using their cryopreserved oocytes. The primary outcome was live birth rate (LBR) per patient after oocyte warming and after ART using fresh oocytes. Secondary outcomes were return rate, utilization rate of the cryopreserved oocytes, laboratory outcomes upon return, and LBR per embryo transfer. A multivariable regression model was developed to identify factors associated with the decision to thaw oocytes as the primary strategy and factors associated with ongoing pregnancy upon return to the clinic. MAIN RESULTS AND THE ROLE OF CHANCE A total of 1353 EOC cycles (mean ± SD, 1.6 ± 0.9 per patient) were performed. At the time of EOC, the mean age was 36.5 ± 2.8 years, mean anti-Müllerian hormone (AMH) was 2.3 ± 2.0 ng/ml, and 174 (20.6%) women had a partner. On average, 13.9 ± 9.2 mature oocytes were cryopreserved. Two hundred thirty-one (27.4%) women returned to the clinic, an average of 39.9 ± 23.4 months after EOC. Upon returning, their mean age was 40.4 ± 3.1 years, mean AMH was 1.5 ± 1.5 ng/ml, and 158/231 (68.3%) patients had a partner. As a primary approach, 110/231 (47.6%) past EOC users embarked on oocyte warming, 50/231 (21.6%) had intrauterine insemination, and 71/231 (30.7%) had ART using fresh own oocytes. Cumulative LBR (CLBR) was 45.9% (106/231) notwithstanding a miscarriage rate (MR) of 30.7% (51/166) in the entire cohort. In total, 141 women performed oocyte warming at some stage in their treatment trajectory. A subset of 90/231 (39.0%) patients exclusively had oocyte warming (41.6 ± 3.0 years, with 10.0 ± 5.2 oocytes warmed per patient). 52/231 (22.5%) patients exclusively had ART using fresh own oocytes (mean age of 39.0 ± 2.8 years, with 9.9 ± 7.4 mature oocytes retrieved per patient). CLBR was 37/90 (41.1%) in the oocyte warming-only group and 25/52 (48.1%) in the OS-only group. MR/transfer was 25.0% and 29.3% in the oocyte warming-only group and the OS-only group, respectively. LIMITATIONS, REASONS FOR CAUTION Both sample size and the retrospective design are limitations of this study. The decision to embark on a specific reproductive treatment strategy was based on patient preference, after counseling on their treatment options. This precludes direct comparison of the efficiency of reproductive treatment options in past EOC users in this study. WIDER IMPLICATIONS OF THE FINDINGS Reporting on clinical outcomes of women who underwent EOC and returned to the clinic to embark on divergent reproductive treatment strategies is mandatory to establish guidelines for best clinical practice in this growing patient population.

Abstract
Purpose: To examine the factors associated with females attending a fertility consultation within 30 days of cancer diagnosis. Methods: This is a retrospective cohort study, including females, 15 to 39 years of age, diagnosed with cancer in Ontario, Canada. Administrative data were used from the Institute of Clinical and Evaluative Sciences for the period 2006 to 2019. A backward selection multivariate logistic regression was performed, with a primary outcome of fertility consultation within 30 days of diagnosis. Results: A total of 20,556 females were included in the study, with 7% having attended a fertility visit within 30 days of diagnosis. Factors associated with being more likely to attend included: not currently having children (odds ratio [OR] = 4.3; confidence interval [95% CI 3.6-5.1]), later years of diagnosis (OR = 3.2; 95% CI [2.8-3.8]), having undergone chemotherapy (OR = 3.6; 95% CI [3.0-4.3]) or radiation therapy (OR = 1.9; 95% CI [1.6-2.2]), and less marginalization within dependency quintiles (OR 1.4; 95% CI [1.1-1.7]). Having a cancer with lower risk to fertility (OR = 0.3; 95% CI [0.2-0.3]), death within a year of diagnosis (OR = 0.4; 95% CI [0.3-0.6]), and residing in a northern region of Ontario (OR = 0.3; 95% CI [0.2-0.4]) were associated with being less likely to attend. For sociodemographic factors, lower levels of income (OR = 0.5; 95% CI [0.4-0.6]) and marginalization with residential instability (OR = 0.6; 95% CI [0.5-0.8]) were associated with being less likely to attend a fertility consultation. Conclusions: Rates for attendance of female fertility consultations after a cancer diagnosis remain low, with disparities by both clinical and demographic factors.

Abstract
This article reports the live birth of a healthy newborn using vitrified-warmed oocytes from fertility preservation before ovarian surgery. The patient in our case underwent two cycles of controlled ovarian stimulation before laparoscopic bilateral ovarian cystectomy for endometriosis, and a total of 23 mature oocytes were vitrified. After surgery, her pathologic reports revealed a serous borderline tumor and endometrioma. Fifteen months after her second surgery of laparoscopic right salpingo-oophorectomy and left ovarian cystectomy owing to recurrence, she had been married by then, and three of the frozen oocytes were thawed for intracytoplasmic sperm injection. These oocytes were cryopreserved for 2.5 years. All three were fertilized, and two grade-A cleavage-stage embryos were transferred. A singleton pregnancy was achieved, resulting in the delivery of a healthy baby boy at 39.3 weeks of gestation. Oocyte cryopreservation is an effective method for fertility preservation prior to ovarian surgery when ovarian function decline is predictable.

Abstract
Infertility is a condition with profound social implications. Indeed, it is not surprising that evolutions in both medicine and society affect the way in vitro fertilization is practiced. The keywords in modern medicine are the four principles, which implicitly involve a constant update of our knowledge and our technologies to fulfill the "prediction" and "personalization" tasks, and a continuous reshaping of our mindset in view of all relevant societal changes to fulfill the "prevention" and "participation" tasks. A worldwide aging population whose life priorities are changing requires that we invest in fertility education, spreading actionable information to allow women and men to make meaningful reproductive choices. Fertility preservation for both medical and nonmedical reasons is still very much overlooked in many countries worldwide, demanding a comprehensive update of our approach, starting from academia and in vitro fertilization laboratories, passing through medical offices, and reaching out to social media. Reproduction medicine should evolve from being a clinical practice to treat a condition to being a holistic approach to guarantee patients' reproductive health and well-being. Oocyte vitrification for fertility preservation is the perfect use case for this transition. This tool is acquiring a new identity to comply with novel indications and social needs, persisting technical challenges, brand-new clinical technologies, and novel revolutions coming from academia. This "views and reviews" piece aims at outlining the advancement of oocyte vitrification from all these tightly connected perspectives.

Abstract
Turner syndrome (TS) is a genetic pathology that affects about 1/2500 newborn females. Turner's syndrome is characterized by highly variable genetic anomalies that consist in a partial or complete deletion of the X sexual chromosome; it can be present as a monosomy or as a mosaicism with two o three different cellular lines. 50% of the patients with Turner's syndrome has a 45 XO karyotype while the remaining cases have karyotypes with mosaicism or X isochromosome or with partial or whole Y chromosome. This pathology is characterized by multiple anomalies that involve physical and cognitive development and in particular endocrine, cardiovascular, reproductive, auditive and visual systems. Integrity of the X chromosome in essential for fertility. In TS is accelerated germ cells apoptosis. About 30% of TS girls have some pubertal development, 10-20% undergo menarche and 2-8% go through spontaneous pregnancy. Women with TS should be informed about the risk of premature menopause and should be referred, if possible, to a specialist evaluation with a doctor expert in assisted reproductive techniques. In adolescents and in adults, Premature Ovarian Insufficiency (POI) can be evaluated clinically and biochemically with the classic combination of amenorrhea and elevated FSH concentrations (hypergonadotropic hypogonadism). However, in postpubertal adolescents and adult women, reproductive hormones may remain within the normal range before POI is clinically evident, despite significant depletion of the ovarian reserve. Today, reproductive medicine offers the opportunity of fertility preservation in women with premature ovarian insufficiency (POI). Two techniques have been suggested such as ovarian cortex cryopreservation and oocytes cryopreservation.

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 purpose of this study was to evaluate whether there is a difference in procedure duration and time spent in the post anaesthesia care unit (PACU) between weekday (WD) and weekend (WE) oocyte retrievals (ORs). This was a retrospective cohort study of patients compared and stratified based on number of oocytes retrieved (1-10, 11-20, and >20). Student's t-test and linear regression models were used to assess the relationship between AMH, BMI, and a number of oocytes retrieved with the duration of procedure and total time spent in the PACU. 664 patients underwent OR of which 578 met inclusion criteria and were analyzed. There were 501 WD OR cases (86%) and 77 (13%) WE ORs. When stratified by number of oocytes retrieved, there was no difference in procedure duration or PACU time between WD vs. WE OR. Longer procedure times were associated with higher BMI (p = 0.04), AMH (p = 0.01) and oocytes retrieved (p < 0.01). Increased PACU times positively correlated with the number of oocytes retrieved (p = 0.04), but not AMH or BMI. While BMI, AMH, and number of oocytes retrieved are associated with longer intra-operative and post-operative recovery times, there is no difference in procedure or recovery time when comparing WD vs. WE procedures.

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.

Abstract
Oocyte cryopreservation has notably increased in recent times, to become an essential part of clinical infertility treatment. Since the 1980s, many improvements in oocyte cryopreservation (OC) have been adopted, including the great advance with the application of vitrification. The commonly used vitrification protocol applies different cryoprotectants (Ethylene glycol and/or DMSO and/or PROH and sucrose and/or Trehalose) and two different steps: firstly, exposure in equilibration solution for 5-15 min, followed by a vitrification solution for 60-90 s at room temperature. The warming method includes a first step for 1 min at 37 °C and 3 subsequent steps at room temperature to remove the cryoprotectant for a total of 9-12 min. In addition, biosafety is a critical aspect to mention, and it is related to devices used during the vitrification, mainly in terms of whether the biological vitrified material comes in direct contact with liquid nitrogen (open vitrification) or not (closed vitrification), where LN2 may contain potentially contaminating viruses or pathogens. Furthermore, during early development major waves of epigenetic reprogramming take place. Recent literature suggests that epigenetic and transcriptomic profiles are sensitive to the stress induced by vitrification, including osmotic shock, temperature, rapid changes of pH and toxicity of cryoprotectants. It is, therefore, important to better understand the potential perturbations of epigenetic modifications that may be associated with the globally used vitrification methods. Therefore, we here discuss the benefits and efficiency of human oocyte vitrification; we also review the evidence surrounding oocyte cryopreservation-related epigenetic modifications and potential epigenetic dysregulations, together with long-term consequences for offspring health.

Abstract
Introduction: There is a lack of metrics to monitor and evaluate fertility care in adolescents and young adults with cancer. This study evaluated the indicator "proportion of cases attending a fertility consult visit ≤30 days from diagnosis of cancer" using the National Quality Forum (NQF) criteria. Methods: This was a retrospective cohort study using administrative data available through the Institute of Clinical Evaluative Sciences in Ontario, Canada. Cases were included if they were diagnosed with a cancer between January 2005 and December 2019, and aged 15-39 years. Fertility consultations were identified by Ontario Health Insurance Plan Claims Database (OHIP) diagnostic codes 628 and 606.Validity was assessed by examining expected differences in the proportion of fertility consults within clinical and demographic factors using chi-square tests. Reliability was assessed by comparing fertility consult visits identified using OHIP diagnostic codes with consults identified using visits to physicians in a registered specialty, using Pearson's correlation coefficient. Results: The population was composed of 39,977 cases, with 6524 (16.3%) having attended a fertility consult. For diagnostic years 2016-2019, differences in the proportion of cases receiving their first fertility consult within 30 days of diagnosis were observed for sex, age, cancer type, hospital type, Local Health Integration Unit, and region (p < 0.001). There was no correlation between the time from diagnosis to fertility consult and time from diagnosis to the first visit to a fertility-related specialty (r = 0.11; p = 0.002). Conclusion: The indicator examined in this article adhered to the criteria described by the NQF, providing a possible metric for reporting on oncofertility care.

Abstract
Objective To report a case of a patient with Turner syndrome (TS) mosaicism and polycystic ovarian syndrome (PCOS), who underwent successful ovarian stimulation, oocyte retrieval, and cryopreservation. Design Case report. Subjects A female patient with mosaic TS (45,X [24%]/46,XX [76%]) and a paternally inherited balanced reciprocal translocation t(2:6) diagnosed with PCOS. Interventions Controlled ovarian stimulation, oocyte retrieval, and cryopreservation. Main outcome measures Successful oocyte retrieval and cryopreservation. Results We report an interesting case of a patient with TS mosaicism 45,X [24%]/46,XX [76%] and a paternally inherited t(2:6) balanced reciprocal translocation, who was diagnosed with PCOS on the basis of oligomenorrhea and ultrasound polycystic ovary morphology (antral follicle count of 17 and >20, left and right ovaries, respectively), underwent 2 cycles of ovarian stimulation, oocyte retrieval, and cryopreservation, resulting in 19 cryopreserved oocytes. Conclusions Our case highlights the importance of early counseling regarding fertility options in patients with mosaic TS and the need for careful monitoring of ovarian reserve during this process, which could be done by measuring the anti-müllerian hormone or antral follicle count. It also underscores the possibility of women with mosaic TS being affected by PCOS.

Abstract
PURPOSE To assess the feasibility and outcomes of oocyte cryopreservation with in vitro maturation (IVM) in post-pubertal girls undergoing fertility preservation (FP) for primary ovarian insufficiency (POI) risk. METHODS Ovarian stimulation was performed with an antagonist protocol or progesterone priming. Ultrasound monitoring was performed transabdominally. Oocytes were retrieved transvaginally under IV sedation. Immature oocytes were subjected to IVM for up to 36 h. All MII oocytes were vitrified. The main outcome measure was the total number of mature oocytes cryopreserved. The secondary outcome was the increase in the mature oocyte yield after IVM. RESULTS Indications for FP included mosaic Turner syndrome (mTS; n = 10), malignancy (n = 3), and POI risk (n = 2). The mean ± SD age, antral follicle count (AFC), and AMH levels were 14.2 ± 1.4 years, 8 ± 5.2 and 1.3 ± 1.3 ng/mL. In girls with mTS, the ovarian reserve was low for age (AFC 7.4 ± 4.7 and AMH 1.4 ± 1.6 ng/mL). Oocyte cryopreservation was possible in all girls with a range of 1-27 mature oocytes obtained, even in those who were previously exposed to chemotherapy or with low ovarian reserve, and no surgical complications were encountered. After IVM, the median mature oocyte yield increased significantly from 7.5 to 10.5 (p = 0.001). CONCLUSIONS Oocyte cryopreservation appears to be feasible and safe in girls as young as 12 years of age at risk for POI The utility of IVM increases the yield of cryopreserved mature oocytes. Prior exposure to chemotherapy or low ovarian reserve should not be an automatic reason to exclude these girls from FP consideration.

Abstract
INTRODUCTION Breast cancer affects almost 1.5 million women worldwide below the age of 45 years each year. Many of these women will be advised to undergo adjuvant chemotherapy to minimize the risk of death or recurrence of the tumor. For these patients, chemotherapy is a known cause of infertility, as it can damage primordial follicles, which can lead to early menopause or premature ovarian insufficiency. This systematic review aims to synthesize the current evidence of the most suitable treatments for fertility preservation. METHODOLOGY This review was performed following the PRISMA guidelines. The authors conducted an extensive search from the last 15 years. Relevant studies were pursued in PubMed, Embase, and the Cochrane Library up until 31 July 2023. A total of seven eligible studies were identified. RESULTS From the reviewed literature, ovarian suppression with gonadotropin-releasing hormone agonists showed promising results in preserving fertility for breast cancer patients undergoing chemotherapy. Additionally, oocyte and embryo cryopreservation demonstrated successful outcomes, with embryo cryopreservation being the most effective option. Notably, the slow-freezing and vitrification methods were both effective in preserving embryos, with vitrification showing superior results in clinical-assisted reproductive technologies. Ovarian tissue cryopreservation emerged as a viable option for prepubertal girls and those unable to undergo conventional ovarian stimulation. The potential of in vitro maturation (IVM) as an alternative method presents a promising avenue for future fertility preservation research. DISCUSSION The most suitable treatments for fertility preservation in young patients is the temporary suppression with luteinizing hormone-releasing analogs, while the patient undergoes chemotherapy and cryopreservation. For cryopreservation, the physicians might deem it necessary to either cryopreserve ovarian tissue taken from the patient before any treatment or cryopreserve embryos/oocytes. Cryopreservation of oocytes and/or embryos is the most effective solution for fertility preservation in women of reproductive age, who have a sufficient ovarian reserve and are diagnosed with breast cancer, regardless of the histological type of the tumor. Because approximately 50% of young breast cancer patients are interested in becoming pregnant right after completion of therapy, the evolution and development of fertility preservation techniques promise to be very exciting.

Abstract
BACKGROUND Previous research has demonstrated that patients have difficulty with the decision to undergo non-urgent egg freezing (EF). This study aimed to investigate the decisional difficulties and possible decisional support mechanisms for patients considering EF, and for their providers. METHODS This qualitative study involved a needs assessment via individual interviews. Participants included patients considering EF at one academic fertility clinic and providers from across Canada who counsel patients considering EF. 25 participants were included (13 providers and 12 patients). The interview guide was developed according to the Ottawa Decision Support Framework. Interviews were transcribed, and transcripts analyzed for themes and concepts using NVIVO 12. FINDINGS Multiple factors contributing to decisional difficulty were identified, including: (1) multiple reproductive options available with differing views from patients/providers regarding their importance; (2) a decision typically made under the pressure of reproductive aging; (3) uncertainty surrounding the technology/inadequate outcome data; (4) the financial burden of EF; (5) inherent uncertainty relating to potential decision regret; and (6) differing perceptions between patients/providers regarding the role providers should play in the decision. Additionally, potential sources of decisional support were identified, including provision of basic information before and/or during initial consultation, followed by an opportunity during or after initial consultation for clarifying information and helping with value judgements. Individualized counselling based on patient values, adequate follow-up, psychosocial counselling, and peer support were also emphasized. CONCLUSIONS More decisional support for women considering EF is needed. Suggestions include a patient decision aid in conjunction with modified healthcare provider counselling, support and follow up.

[PMID: 37734120 DOI: 10.1016/j.rbmo.2023.103294] [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: 04/03/2023] [Revised: 06/08/2023] [Accepted: 07/17/2023] [Indexed: 09/23/2023]
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
Immature oocyte (germinal vesicle stage, GV) vitrification can avoid a cycle of ovarian stimulation, which is friendly to patients with hormone-sensitive tumors. However, the in vitro maturation of vitrification-thawed GV oocyte usually results in aneuploidy, and the underlying mechanism remains unclear. Stable spindle poles are important for accurate chromosome segregation. Acentriolar microtubule-organizing centers (aMTOCs) undergo fragmentation and reaggregation to form spindle poles. Microtubule nucleation is facilitated via the perichromosome Ran after GVBD, which plays an important role in aMTOCs fragmentation. This study showed that vitrification may reduce microtubule density by decreasing perichromosomal Ran levels, which reduced the localization of pKIF11, thereby decreased the fragmentation of aMTOCs and formed a more focused spindle pole, ultimately resulted in aneuploidy. This study revealed the mechanism of abnormal spindle pole formation in vitrified oocytes and offered a theoretical support to further improve the quality of vitrified oocytes.

Abstract
PURPOSE To evaluate embryo ploidy in a cohort of patients who underwent preimplantation genetic testing for aneuploidy (PGT-A) with vitrified oocytes compared to fresh oocytes. METHODS Patients who underwent their first autologous oocyte vitrification and warming followed by in vitro fertilization (IVF) and trophectoderm biopsy for PGT-A between 1/1/2017 and 12/31/2021 at a single academic institution were included. Patients were compared 1:3 to age-matched controls who underwent their first IVF cycle with fresh oocytes and subsequent trophectoderm biopsy for PGT-A. The primary outcome was the proportions of euploid, mosaic, and aneuploid embryos between those using vitrified versus fresh oocytes. RESULTS 117 patients who cryopreserved a total of 1,272 mature oocytes were included in the study and were matched with 351 controls using fresh oocytes. The average age was 36.9 ± 2.6 years, and the median interval between oocyte vitrification and warming was 38 months. There were similar numbers of mature oocytes (10.9 ± 4.9 vs. 11.1 ± 6.3, P = .67), fertilized oocytes (7.8 ± 4.0 vs. 8.7 ± 5.5, P = .10), and blastocysts per patient (5.1 ± 3.1 vs. 5.8 ± 4.3, P = .10) between those using vitrified versus fresh oocytes. In terms of embryo ploidy results, there were no statistically significant differences in rates of euploidy (40.1% vs. 41.6%), mosaicism (15.7% vs. 12.0%), or aneuploidy (44.3% vs. 46.4%) (P = .06) between the two groups. CONCLUSIONS Oocyte vitrification with subsequent warming, fertilization, and trophectoderm biopsy for PGT-A was not associated with adverse chromosomal competence when compared to age-matched controls utilizing fresh oocytes.

Abstract
This narrative review article comprehensively explores the multifaceted landscape of social egg freezing, delving into its medical, ethical, societal, psychological, legal, and cultural dimensions. Oocyte cryopreservation, a developing procedure, gives women the chance to match their life goals with fertility goals. Informed decision-making, morally sound guidance, and open communication are all stressed by ethical considerations. Family planning practices, workplace cultures, and gender equality all have an impact on societal dynamics. The process's emotional toll and associated coping mechanisms are highlighted by psychological elements. Legal and policy frameworks need constant ethical reflection and understanding of the regulatory environment. Religious and cultural views highlight the variety of perspectives that influence attitudes toward this practice. For responsible practice to ensure individual liberty while navigating the evolving landscape of reproductive options, it is essential to comprehend how these aspects interact.

Abstract
Regulations governing assisted reproduction control the degree to which gamete donation is legal and how people providing genetic material are selected and compensated. The United States and Spain are both global leaders in fertility treatment with donor oocytes. Yet both countries take different approaches to how egg donation is regulated. The US model reveals a hierarchically organized form of gendered eugenics. In Spain, the eugenic aspects of donor selection are more subtle. Drawing upon fieldwork in the United States and Spain, this article examines (1) how compensated egg donation operates under two regulatory settings, (2) the implications for egg donors as providers of bioproducts, and (3) how advances in oocyte vitrification enhances the commodity quality of human eggs. By comparing these two reproductive bioeconomies we gain insight into how different cultural, medical, and ethical frameworks intersect with egg donor embodied experiences.

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.

Abstract
Third-party reproduction refers to the use of eggs, sperm, or embryos that have been donated by a third person (the donor) to enable individuals or couples (the intended parents) with infertility to have a child. This differs from the traditional father-mother family model with no third parties involved. Third-party reproduction is also used by couples that are unable to reproduce by traditional means, same-sex couples, and men and women without a partner. This has emerged as a treatment option with great success rates in a scene of changing family constellations. Consequently, this therapeutic alternative has become a realistic solution which has brought great satisfaction and happiness to people who otherwise would have not been able to achieve parenthood if these options were not medically and legally available.

Abstract
OBJECTIVE This study aimed to compare the effects of two brands of commercial vitrification carriers on pregnancy outcomes in freeze-thaw cycles. METHODS We included 4871 patients who underwent a "freeze all" strategy using the commercial carriers J.Y. straw and OYASHIPS straw in the Reproductive Center of the First Hospital of Jilin University. The pregnancy outcomes of cleavage-stage embryos and blastocysts were studied separately. Detailed data and the safety of children born from mothers with the two types of carriers were also compared. RESULTS Patients who used J.Y. straw had similar clinical pregnancy and live birth rates with one and two cleavage-stage embryo transplantation to those who used OYASHIPS straw. In patients who had blastocyst transplantation, the clinical pregnancy rate of one blastocyst transplanted in those who used OYASHIPS straw was significantly higher than that in those who used J.Y. straw (57.85% vs 47.09%). Among children born from mothers who used J.Y. straw, the congenital disability rate was significantly higher than that in those with OYASHIPS straw. CONCLUSION The OYASHIPS straw carrier is cheap and can achieve clinical pregnancy and live birth outcomes comparable to those of J.Y. straw. Therefore, OYASHIPS straw is a good alternative option.

Abstract
Several mechanisms have been implicated in the pathogenesis of endometriosis-related infertility. For patients considering surgery, the risk of iatrogenic injury is among the most important factors in the context of fertility preservation, along with age and individual reproductive goals. In the case of endometrioma excision, evidence overwhelmingly demonstrates the negative impact of surgery on ovarian reserve, with significant reductions in antimullerian hormone (up to 30% in unilateral versus up to 44% in bilateral endometriomas). The surgical endometriosis patient should be thoroughly counseled regarding fertility preservation and discussion should include tissue, embryo, and oocyte cryopreservation options. For the latter, data support cryopreservation of 10-15 oocytes in women ≤35 years and over 20 for those >35 years for a realistic chance to achieve one or more live births. When performing surgical interventions for endometriosis, reproductive surgeons should employ fertility-conserving surgical methods to reduce the likelihood of postoperative iatrogenic diminished ovarian reserve.

Abstract
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
Background Fertility preservation is an important healthcare focus in the paediatric and adolescent population when gonadotoxic treatments are required. Ovarian stimulation (OS) resulting in oocyte cryopreservation is a well-established fertility preservation option in the adult population. It's utility, however, is little known in young patients. The purpose of this review was to synthesise the available literature on OS in patients ≤18 years old, to identify gaps in current research and provide suggestions for future research directions. Methods Using PRISMA guidelines, a systematic review of the literature was performed for all relevant full-text articles published in English in Medline, Embase, the Cochrane Library and Google Scholar databases. The search strategy used a combination of subject headings and generic terms related to the study topic and population. Two reviewers independently screened studies for eligibility, extracted data and assessed the risk of bias. Characteristics of the studies, objectives and key findings were extracted and summarised in a narrative synthesis. Results Database search and manual review identified 922 studies, 899 were eliminated based on defined exclusion criteria. Twenty-three studies were included and comprised 468 participants aged ≤18 years who underwent OS (median 15.2, range 7-18 years old). Only three patients were premenarchal, and four patients were on treatment to suppress puberty. Patients had OS for a broad range of indications including oncology treatment, transgender care and Turner syndrome. A total of 488 cycles of OS were completed, with all but 18 of these cycles (96.3%) successfully resulting in cryopreserved mature oocytes (median 10 oocytes, range 0-35). Fifty-three cycles (9.8%) were cancelled. Complications were rare (<1%). One pregnancy was reported from a female who had OS aged 17 years old. Conclusion This systematic review demonstrates that OS and oocyte cryopreservation is achievable in young females however there are only a few cases in the literature describing OS in premenarcheal children or those who have suppressed puberty. There is little proof that OS can lead to pregnancy in adolescents, and no proof that this can be achieved in premenarchal girls. Therefore it should be regarded as an innovative procedure for adolescents and experimental for premenarcheal girls.

Eur J Haematol 2023. [PMID: 37308461 DOI: 10.1111/ejh.14027] [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: 04/07/2023] [Revised: 05/30/2023] [Accepted: 06/01/2023] [Indexed: 06/14/2023]
Abstract
OBJECTIVES Allogeneic hematopoietic stem-cell transplantation (HCT) is the only curative option for most hematologic malignancies. However, HSCT can cause early menopause and various complications in premenopausal women. Therefore, we aimed to investigate risk factors predicting early menopause and its clinical implications among survivors post HCT. METHODS We retrospectively analyzed 30 adult women who had received HCT at premenopausal status between 2015 and 2018. We excluded patients who had received autologous stem cell transplantation, had relapsed, or died of any cause within 2 years of HCT. RESULTS The median age at HCT was 41.6 years (range, 22-53). Post-HCT menopause was identified in 90% of myeloablative conditioning (MAC) HCT and 55% of reduced-intensity conditioning (RIC) HCT (p = .101). In the multivariate analysis, the post-HCT menopausal risk was 21 times higher in a MAC regimen containing 4 days of busulfan (p = .016) and 9.3 times higher in RIC regimens containing 2-3 days of busulfan (p = .033) than that of non-busulfan-based conditioning regimens. CONCLUSIONS Higher busulfan dose in conditioning regimens is the most significant risk factor affecting post-HCT early menopause. Considering our data, we need to decide on conditioning regimens and individualized fertility counseling before HCT for premenopausal women.

Vitrification with Dimethyl Sulfoxide Induces Transcriptomic Alteration of Gene and Transposable Element Expression in Immature Human Oocytes. Genes (Basel) 2023; 14:1232.

Abstract
Despite substantial advancements in the field of cryobiology, oocyte and embryo cryopreservation still compromise developmental competence. Furthermore, dimethyl sulfoxide (DMSO), one of the most commonly used cryoprotectants, has been found to exert potent effects on the epigenetic landscape of cultured human cells, as well as mouse oocytes and embryos. Little is known about its impact on human oocytes. Additionally, few studies investigate the effects of DMSO on transposable elements (TE), the control of which is essential for the maintenance of genomic instability. The objective of this study was to investigate the impact of vitrification with DMSO-containing cryoprotectant on the transcriptome, including on TEs, of human oocytes. Twenty-four oocytes at the GV stage were donated by four healthy women undergoing elective oocyte cryopreservation. Oocytes were paired such that half from each patient were vitrified with DMSO-containing cryoprotectant (Vitrified Cohort), while the other half were snap frozen in phosphate buffer, unexposed to DMSO (Non-Vitrified Cohort). All oocytes underwent RNA sequencing via a method with high fidelity for single cell analysis, and which allows for the analysis of TE expression through Switching Mechanism at the 5'-end of the RNA Transcript sequencing 2 (SMARTseq2), followed by functional enrichment analysis. Of the 27,837 genes identified by SMARTseq2, 7331 (26.3%) were differentially expressed (p < 0.05). There was a significant dysregulation of genes involved in chromatin and histone modification. Mitochondrial function, as well as the Wnt, insulin, mTOR, HIPPO, and MAPK signaling pathways were also altered. The expression of TEs was positively correlated with the expression of PIWIL2, DNMT3A, and DNMT3B, and negatively correlated with age. These findings suggest that the current standard process of oocyte vitrification, involving DMSO-containing cryoprotectant, induces significant transcriptome changes, including those involving TEs.

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
Fertility preservation is a major concern in young patients diagnosed with breast cancer and planning to receive multimodality treatment, including gonadotoxic chemotherapy with or without age-related decline through long-term endocrine therapy. Most breast cancer patients undergo multimodality treatments; many short-term and long-term side effects arise during these therapies. One of the most detrimental side effects is reduced fertility due to gonadotoxic treatments with resultant psychosocial stress. Cryopreservation of oocytes, embryos, and ovarian tissue are currently available fertility preservation methods for these patients. As an adjunct to these methods, in vitro maturation or gonadotropin-releasing hormone agonist could also be considered. It is also essential to communicate well with patients in the decision-making process on fertility preservation. It is essential to refer patients diagnosed with breast cancer on time to fertility specialists for individualized treatment, which may lead to desirable outcomes. To do so, a multimodal team-based approach and in-depth discussion on the treatment of breast cancer and fertility preservation is crucial. This review aims to summarize infertility risk related to currently available breast cancer treatment, options for fertility preservation and its details, barriers to oncofertility counseling, and psychosocial issues.

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
The broad conceptualization of fertility preservation and restoration has become already a major concern in the modern western world since a large number of individuals often face it in the everyday life. Driven by different health conditions and/or social reasons, a variety of patients currently rely on routinely and non-routinely applied assisted reproductive technologies, and mostly on the possibility to cryopreserve gametes and/or gonadal tissues for expanding their reproductive lifespan. This review embraces the data present in human-focused literature regarding the up-to-date methodologies and tools contemporarily applied in IVF laboratories' clinical setting of the oocyte, sperm, and embryo cryopreservation and explores the latest news and issues related to the optimization of methods used in ovarian and testicular tissue cryopreservation.

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.

Acceptance and willingness-to-pay for oocyte cryopreservation in medical versus age-related fertility preservation scenarios among Swedish female university students. Sci Rep 2023; 13:5325.

Abstract
Oocytes can be effectively cryopreserved and stored for future use in in-vitro fertilisation. Oocyte cryopreservation (OC) can therefore mitigate different threats to female fertility, but attitudes and policies often seem more favourable in medical rather than age-related fertility preservation scenarios. The value of OC for potential candidates may be perceived differently depending on the indications, although relevant empirical data are lacking. An adequately powered sample of Swedish female university students (n = 270; median age 25; range 19-35) were randomly delivered a medical (n = 130) or age-related (n = 140) fertility preservation scenario within an online survey. Sociodemographic factors, reproductive experiences, and awareness about OC were not significantly different between the groups. Differences in four outcomes were studied: proportions of respondents (1) positive to the use of OC, (2) positive to public funding for OC, or (3) open to considering OC; and (4) willingness-to-pay (WTP) for OC, measured in thousand Swedish krona (K SEK) through contingent valuation. There were no significant differences in the proportions of respondents positive to the use of OC (medical: 96%; age-related: 93%) or open to consider it (medical: 90%; age-related: 88%) in each scenario. However, public funding had significantly greater support in the medical scenario (85%) than in the age-related one (64%). The median WTP (45 K SEK ≈ 4.15 K EUR) approximated the current Swedish market price for a single elective cycle and was not significantly different between the scenarios (Cliff's delta - 0.009; 95%CI - 0.146, 0.128). These findings suggest that it may be inappropriate to justify counselling and priority policies only on the assumption that fertility preservation with OC for medical indications is more beneficial to women than when the same technique is used for age-related reasons. However, it would be interesting to investigate further why public funding appears more debatable than the treatment itself.
