Exploring the knowledge, attitudes, and perceptions of women of reproductive age towards fertility and elective oocyte cryopreservation for age-related fertility decline in the UK: a cross-sectional survey.

STUDY QUESTION: What are the knowledge, perceptions and attitudes towards fertility and elective oocyte cryopreservation (OC) for age-related fertility decline (ARFD) in women in the UK? SUMMARY ANSWER: Awareness of OC for ARFD has reportedly improved compared to studies carried out almost a decade ago, but inconsistencies in knowledge remain regarding the rate of miscarriage amongst specific age groups, the financial costs and optimal age to undergo OC for ARFD. WHAT IS KNOWN ALREADY: The age of first-time motherhood has increased amongst western societies, with many women of reproductive age underestimating the impact of age on fertility. Further understanding of women's awareness of their fertility, the options available to preserve it and the barriers for seeking treatment earlier are required in order to prevent the risk of involuntary childlessness. STUDY DESIGN, SIZE, DURATION: A hyperlink to a cross-sectional survey was posted on social media (Instagram) between 25 February 2021 and 11 March 2021. PARTICIPANTS/MATERIALS, SETTING, METHODS: Women from the general population aged 18-50 years were invited to complete the survey. MAIN RESULTS AND THE ROLE OF CHANCE: In total, 5482 women fulfilled the inclusion criteria and completed the survey. The mean age of participants was 35.0 years (SD 10.25; range 16-52). Three quarters (74.1%; n = 4055) disagreed or strongly disagreed they felt well informed regarding the options available to preserve their fertility, in case of a health-related problem or ARFD. The majority overestimated the risk of miscarriage in women aged ≥30 years old, with 14.5% correctly answering 20%, but underestimated the risks in women ≥40, as 20.1% correctly answered 40-50%. Three quarters (73.2%; n = 4007) reported an awareness of OC for ARFD and 65.8% (n = 3605) reported that they would consider undergoing the procedure. The number of women who considered OC for ARFD across age groups were as follows: 18-25 (8.3%; n = 300), 26-30 (35.8%; n = 1289), 31-35 (45.9%; n = 1654), 36-40 (9.6%; n = 347), 41-45 (0.3%; n = 13), and 46-50 (0.1%; n = 2). The majority of women (81.3%; n = 4443) underestimated the cost of a single cycle of OC for ARFD (<£5000). Furthermore, 10.4% (n = 566) believed a single cycle would be adequate enough to retrieve sufficient oocytes for cryopreservation. Approximately 11.0% (n = 599) believed OC for ARFD may pose significant health risks and affect future fertility. Less than half agreed or strongly agreed that the lack of awareness regarding OC for ARFD has impacted the likelihood of pursuing this method of fertility preservation further (41.4%; n = 2259). LIMITATIONS, REASONS FOR CAUTION: Results from cross-sectional studies are limited as interpretations made are merely associations and not of causal relationships. The online nature of participant recruitment is subject to selection bias, considering women with access to social media are often from higher socioeconomic and education backgrounds, thus limiting generalizability of the findings. WIDER IMPLICATIONS OF THE FINDINGS: Further education regarding the financial costs and optimal age to undergo elective OC to increase the chances of successful livebirth are required. Clinicians should encourage earlier fertility counselling to ensure that OC is deemed a preventative measure of ARFD, rather than an ultimate recourse to saving declining fertility. STUDY FUNDING/COMPETING INTEREST(S): No funding was required for this article. There are no conflicts of interests to declare. TRIAL REGISTRATION NUMBER: N/A.

Knowledge and attitude of reproductive-aged women towards planned oocyte cryopreservation in the United Arab Emirates.

BACKGROUND: Delayed conception is associated with a decline in oocyte number and quality. Oocyte cryopreservation techniques are used for medical or non-medical (elective) reasons. We aim to assess the knowledge and attitudes towards planned oocyte cryopreservation (POC) among reproductive-aged women in the United Arab Emirates (UAE) and to investigate the factors interfering with their decisions. METHODS: A cross-sectional study on 422 women (18-38 years) living in the UAE, using an online questionnaire with three sections: sociodemographic, knowledge, and attitudes towards POC. RESULTS: 91.2% of participants have heard of POC, 84.1% hold a bachelor's degree or higher, 65.4% with medical background, 54.3% employed, and 79.2% live in Sharjah and Dubai. Consideration of POC was significantly associated with age (p = 0.011), employment (p = 0.002), the Emirates they live (p < 0.001), and if they have heard of POC (p = 0.036). Mean knowledge score was 44.44%, which was significantly higher among those considering POC (49.66% vs. 40.55%), and social media was their main source of information. About 57% will not consider POC, mainly due to cost, cultural issues, and safety. Determinants of knowledge score were marital status (B = 0.44; 95%CI: 0.09-0.79; p value = 0.014) and education level (B = 0.35; 95%CI: 0.13-0.58; p value = 0.002), and after adjustment, only the education level remained significantly associated with knowledge score (B = 0.24; 95%CI: 0.01-0.47; p value = 0.042). CONCLUSION: Despite many participants being motivated to undergo POC, majority had poor knowledge, and cost was the main barrier. The main determinant of the knowledge score was education level. Awareness among couples of consequences of delaying childbearing and comprehensive information from medical practitioners are highly needed.

Age-related fertility decline: is there a role for elective ovarian tissue cryopreservation?

Age-related fertility decline (ARFD) is a prevalent concern amongst western cultures due to the increasing age of first-time motherhood. Elective oocyte and embryo cryopreservation remain the most established methods of fertility preservation, providing women the opportunity of reproductive autonomy to preserve their fertility and extend their childbearing years to prevent involuntary childlessness. Whilst ovarian cortex cryopreservation has been used to preserve reproductive potential in women for medical reasons, such as in pre- or peripubertal girls undergoing gonadotoxic chemotherapy, it has not yet been considered in the context of ARFD. As artificial reproductive technology (ART) and surgical methods of fertility preservation continue to evolve, it is a judicious time to review current evidence and consider alternative options for women wishing to delay their fertility. This article critically appraises elective oocyte cryopreservation as an option for women who use it to mitigate the risk of ARFD and introduces the prospect of elective ovarian cortex cryopreservation as an alternative.

Usage and cost-effectiveness of elective oocyte freezing: a retrospective observational study.

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.

Pfizer SARS-CoV-2 BNT162b2 mRNA vaccination (BNT162b2) has no adverse effect on elective oocyte cryopreservation outcomes.

RESEARCH QUESTION: Do elective oocyte cryopreservation outcomes in women 1-13 months after SARS-CoV-2 vaccination alter compared with unvaccinated women and do different time intervals between vaccination and ovarian stimulation impact these outcomes? DESIGN: This retrospective cohort study, conducted in a university-affiliated IVF centre, included 232 elective oocyte cryopreservation cycles of vaccinated and unvaccinated patients, without previous infection with the SARS-CoV-2 virus, between December 2020 and January 2022. Two control groups - pre-pandemic (January 2019 to February 2020) and intra-pandemic (December 2020 to January 2022) unvaccinated groups - were compared with the vaccinated group, further divided into four subgroups (under 3, 3-6, 6-9 and 9-13 months). The primary outcome was the elective oocyte cryopreservation cycle outcomes - number of retrieved and number of mature oocytes. RESULTS: The vaccinated group demonstrated comparable outcomes with regards to number of retrieved and mature oocytes compared with the pre-pandemic and intra-pandemic unvaccinated groups (12.6 ± 8.0 versus 13.0 ± 8.2 and 12.5 ± 7.4 retrieved and 10.1 ± 6.9 versus 9.5 ± 6.4 and 10.1 ± 6.3 mature oocytes, respectively; not significant for both). Similar results were noted in a comparison between the intra-pandemic unvaccinated group and the four vaccinated subgroups. No correlation was found between the parameter of days from vaccination and cycle outcomes. Similarly, analysis of covariance showed no association between vaccination status and timing and number of mature oocytes. CONCLUSIONS: The SARS-CoV-2 vaccination does not alter the outcomes of elective oocyte cryopreservation procedures. This is true even in a relatively long time interval of 9 to 13 months from vaccination.

Clinical outcome of planned oocyte cryopreservation at advanced age.

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.

Reproductive outcomes from ten years of elective oocyte cryopreservation.

RESEARCH QUESTION: To assess the relationship between the number of oocytes retrieved during elective oocyte cryopreservation (EOC) cycles with various clinical, biochemical, and radiological markers, including age, body mass index (BMI), baseline anti-Müllerian hormone (AMH), antral follicle count (AFC), Oestradiol level (E2) and total number of follicles ≥ 12 mm on the day of trigger. To also report the reproductive outcomes from women who underwent EOC. METHODS: A retrospective cohort of 373 women embarking on EOC and autologous oocyte thaw cycles between 2008 and 2018 from a single London clinic in the United Kingdom. RESULTS: 483 stimulation cycles were undertaken amongst 373 women. The median (range) age at cryopreservation was 38 (26-47) years old. The median numbers of oocytes retrieved per cycle was 8 (0-37) and the median total oocytes cryopreserved per woman was 8 (0-45). BMI, E2 level and number of follicles ≥ 12 mm at trigger were all significant predictors of oocyte yield. Multivariate analysis confirmed there was no significant relationship between AFC or AMH, whilst on univariate analysis statistical significance was proven. Thirty six women returned to use their cryopreserved oocytes, of which there were 41 autologous oocyte thaw cycles undertaken. There were 12 successful livebirths achieved by 11 women. The overall livebirth rate was 26.8% per cycle. No livebirths were achieved in women who underwent EOC ≥ 40 years old, and 82% of all livebirths were achieved in women who had done so between 36 and 39 years old. CONCLUSION: Clinical, biochemical and radiological markers can predict oocyte yield in EOC cycles. Reproductive outcomes are more favourable when cryopreservation is performed before the age of 36, with lower success rates of livebirth observed in women aged 40 years and above.

Current perspectives on social oocyte freezing.

Demand for oocyte freezing in absence of a medical indication is growing as women delay childbirth and seek to extend the window of opportunity for parenthood. The optimum age for oocyte freezing is below 35 years, whereas currently the mean age of women undergoing oocyte freezing in the UK is 38 years. Nearly half of women undergoing oocyte freezing are not in a relationship. The treatment is not publicly funded and the average price for a complete oocyte freezing and thawing cycle, including annual storage fees, could reach over £7000. The live birth rate per oocyte thaw cycle is 18% and is influenced by age at the time of oocyte freezing. Women considering social oocyte freezing should be thoroughly counselled about the efficacy, limitations, cost implications and alternatives to oocyte freezing and provided with the appropriate support to enable a truly informed reproductive choice.

'Why have women not returned to use their frozen oocytes?': a 5-year follow-up of women after planned oocyte cryopreservation.

RESEARCH QUESTION: What are the reproductive choices and retrospective reflections of women at least 4 years after planned oocyte cryopreservation (POC)? DESIGN: This was an internet survey, using the REDCap application, of women who underwent POC, at a single-centre university-affiliated IVF unit, 4-8 years before the survey. The questionnaire addressed reproductive choices and outcomes following POC. RESULTS: Seventy-nine women who underwent POC during 2011-2014 were invited to participate, and 70 (89%) responded. Mean age at cryopreservation was 37.1 ± 2.4 (range 30-41) years, mean age at study participation 42.6 ± 2.6 (range 35-48) years, and mean time from first cryopreservation cycle to study participation 5.5 ± 1.3 (range 4-8) years. The main retrospectively reported reason for POC was not wanting to become pregnant without a partner (59, 84%). During the follow-up period, 44 women (63%) attempted to conceive either naturally or by assisted reproductive technology using fresh or cryopreserved oocytes. Of those, 28 women achieved a live birth (64% of those who tried to conceive). Fourteen respondents (20% of all respondents) reported using their cryopreserved oocytes, and three (21%) achieved a birth using those oocytes. Fifteen women (34%) of those who tried to conceive used donor spermatozoa. CONCLUSIONS: The most common reasons for not using frozen oocytes were achieving pregnancy without frozen oocytes or preferring not to have a child without a partner. A considerable proportion of women who had POC and were not interested in being a single parent by choice eventually try to conceive using donor spermatozoa several years later.

The quality of information about elective oocyte cryopreservation (EOC) on Australian fertility clinic websites.

BACKGROUND: The number of women who undergo elective oocyte cryopreservation (EOC) in the hope of preserving their fertility is increasing. Fertility clinic websites often serve as the first point of contact for women contemplating EOC. There are no guidelines for Australian fertility clinics regarding how information about procedures should be presented. AIM: To assess the quality of information presented on EOC on Australian fertility clinic websites. MATERIALS AND METHODS: A desktop audit was conducted of the websites of Australian fertility clinics offering EOC (n = 21) and the information provided about EOC was recorded. To allow comparison, a scoring matrix used in a study of the quality of EOC information on clinic websites in the USA was used to assess the quality of the information. The possible range of scores on this measure is 0-13. RESULTS: The mean information quality score for all clinic websites was 4.3 (range 2-8). More than half of the clinic websites (57%) had scores classified as 'poor', indicating that women are not receiving the information they need to make well-informed choices. CONCLUSION: Providing information on clinic websites that is transparent and scientifically accurate, that states the risks involved in the procedure, and its full cost is essential to allow women to make informed decisions. The scoring matrix used in this study to assess the quality of information relating to EOC can guide best practice for clinics in advertising EOC to prospective customers.

Decision making processes of women who seek elective oocyte cryopreservation.

PURPOSE: The aim of this study is to analyze women's opinions and their decision making processes regarding elective oocyte cryopreservation (OC). METHODS: One hundred twenty-four women who had elective OC counseling at the CHA Seoul Fertility Center were asked to complete a survey after their first visit. Data collection regarding age, marital status, monthly income, occupation, religion, reproductive history, questions about the participant's view on their own fecundity, and future parenthood were included. The modified Reproductive Concerns After Cancer scale and the Decisional Conflict Scale were used for analysis. RESULTS: The participants' mean age was 37.1 ± 4.8 years old. Eighty-six percent of the participants had regular periods. Ninety-two percent thought it was important to have their own biological offspring, and 86% were willing to pursue OC. Forty-nine percent appeared to have high DCS scores regarding making a decision of OC. Sixty-eight percent pursued OC, and the mean number of oocytes cryopreserved per patient was 10.5 ± 8.3. Multivariate analysis revealed that age was the only factor associated with high DCS scores (P = 0.002). Feeling less fertile than other women of same age and low DCS scores were the factors associated with pursuing OC (P = 0.02 and 0.004, respectively) after adjusting for possible confounding factors, including age. CONCLUSIONS: Older women had more difficulties in making decisions about OC. Adjusting for age, women who thought that they were less fertile than other women of same age and those with lower decisional conflict were more likely to pursue OC. Further studies should focus on the validation of older women's decisional conflicts regarding OC.

Random-start ovarian stimulation in women desiring elective cryopreservation of oocytes.

The current study investigates the utility of random-start ovarian stimulation in women desiring elective oocyte cryopreservation. Women in the study cohort underwent random-start ovarian stimulation, and were subdivided based on the phase of the menstrual cycle that ovarian stimulation began, i.e. early follicular, late follicular or luteal phase. Women undergoing conventional cycle day (CD) 2/3 ovarian stimulation start were controls. A total of 1302 women were included - 859 (66.0%) conventional CD 2/3, 342 (26.3%) early follicular, 42 (3.2%) late follicular and 59 (4.5%) luteal ovarian stimulation starts. There was no difference in the demographics or baseline ovarian stimulation characteristics. The duration of ovarian stimulation (11 versus 9 days; P < 0.001) and total dosage of gonadotrophins administered (4095.5 versus 3155 IU; P < 0.001) was higher in the random-start group. The number of total and MII oocytes in the control and random-start groups was similar. A non-significant trend towards increased cycle cancellation was noted in the late follicular start group (7.1%). Study findings indicate the number of total and MII oocytes derived from random-start protocols initiated during any phase of the menstrual cycle is similar to conventional CD 2/3 ovarian stimulation start protocols in women desiring elective oocyte cryopreservation.

Is employer coverage of elective egg freezing coercive?: a survey of medical students' knowledge, intentions, and attitudes towards elective egg freezing and employer coverage.

PURPOSE: The purpose of this study was to understand medical students' knowledge, intentions, and attitudes towards oocyte cryopreservation and employer coverage of such treatment. METHODS: This cross-sectional study was performed via an online cross-sectional survey distributed to 280 female medical students from March through August 2016. Demographics, attitudes towards employer coverage, and factors influencing decision-making were assessed via a self-reported multiple-choice questionnaire. The relationship between respondents' attitudes towards employer coverage and other parameters was analyzed. RESULTS: A total of 99 responses were obtained out of 280 female medical students. Most respondents (71%) would consider oocyte cryopreservation (potential freezers), although 8% would not consider the procedure and 21% were unsure. Seventy-six percent of respondents felt pressure to delay childbearing. Potential freezers were more likely to be single (p = 0.001), to report feeling pressure to delay childbearing (p = 0.016), and to consider egg freezing if offered by an employer (p < 0.001). Importantly, 71% percent did not view employer coverage as coercive and 77% of respondents would not delay childbearing due to employer coverage. Factors influencing decision-making in potential freezers were absence of a suitable partner (83%), likelihood of success (95%), and health of offspring (94%), among others. Knowledge about the low chance of pregnancy per oocyte (6-10%) would influence decision-making in 42% of potential freezers. CONCLUSION: Oocyte freezing is an acceptable strategy for the majority of young women surveyed. Pressure to delay childbearing was related to openness to freeze eggs. The majority of respondents did not find employer coverage for egg freezing coercive although further research is needed with larger, representative samples to ascertain the relationship between pressure to delay childbearing due to work demands and employer coverage for egg freezing.

Knowledge, attitudes, and intentions toward fertility awareness and oocyte cryopreservation among obstetrics and gynecology resident physicians.

STUDY QUESTION: What knowledge, attitudes and intentions do US obstetrics and gynecology (OB/GYN) residents have toward discussing age-related fertility decline and oocyte cryopreservation with their patients? SUMMARY ANSWER: Most OB/GYN residents believe that age-related fertility decline, but not oocyte cryopreservation, should be discussed during well-woman annual exams; furthermore, nearly half of residents overestimated the age at which female fertility markedly declines. WHAT IS KNOWN ALREADY: Oocyte cryopreservation can be utilized to preserve fertility potential. Currently, no studies of US OB/GYN residents exist that question their knowledge, attitudes, and intentions toward discussing age-related fertility decline and oocyte cryopreservation with patients. STUDY DESIGN, SIZE, DURATION: A cross-sectional online survey was conducted during the fall of 2014 among residents in American Council for Graduate (ACOG) Medical Education-approved OB/GYN residency programs. Program directors were emailed via the ACOG Council on Resident Education in Obstetrics and Gynecology server listing and asked to solicit resident participation. PARTICIPANTS/MATERIALS, SETTING, METHODS: Participants included 238 residents evenly distributed between post-graduate years 1-4 with varied post-residency plans; 90% of residents were women and 75% were 26-30 years old. The survey was divided into three sections: demographics, fertility awareness, and attitudes toward discussing fertility preservation options with patients. Descriptive and inferential statistics were conducted. MAIN RESULTS AND THE ROLE OF CHANCE: A strong majority of residents (83%) believed an OB/GYN should initiate discussions about age-related fertility decline with patients (mean patient age 31.8), and 73% percent believed these discussions should be part of an annual exam. One third of residents overestimated the age at which there is a slight decline in female fertility, while nearly half of residents overestimated the age at which female fertility markedly declines. Over three-quarters of residents (78.4%) also overestimated the likelihood of success using assisted reproductive treatments (ARTs). Residents were likely to support oocyte cryopreservation in cancer patients irrespective of the woman's age, but much less likely to support elective oocyte cryopreservation. For elective oocyte cryopreservation, 40% believed OB/GYNs should initiate discussions with patients (mean age 31.1), while only 20% believed this topic should be part of an annual exam. LIMITATIONS, REASONS FOR CAUTION: Because the study invitation was sent through US OB/GYN residency program directors rather than directly to residents, it is possible that some residents did not receive the invitation to participate. This limits the generalizability of the findings. WIDER IMPLICATIONS OF THE FINDINGS: Within the USA, there appears to be a critical need for improved education on fertility decline in OB/GYN residency programs. To promote informed reproductive decision-making among patients, efforts should be made to help OB/GYNs provide comprehensive fertility education to all women, while also respecting patient choices. STUDY FUNDING/COMPETING INTERESTS: None.

Awareness, Attitude, and Fertility Desire in Elective Oocyte Cryopreservation of Adults in Four Areas of China.

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.

Outcomes of Social Egg Freezing: A Cohort Study and a Comprehensive Literature Review.

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.

Oocyte Cryopreservation for Medical and Planned Indications: A Practical Guide and Overview.

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.

Randomized control trial of a decision aid for women considering elective egg freezing: The Eggsurance study protocol.

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.

Evidence of profound ovarian suppression on combined hormonal contraception resulting in dramatically different ovarian reserve testing and oocyte retrieval outcomes: case report and review of the literature.

OBJECTIVE: To describe a case report and demonstrate that degree of ovarian suppression with continuous combined hormonal contraception (CHC) may be more profound than previously described and may present similarly as decreased ovarian reserve. DESIGN: Case report and review of the literature. SETTING: Private practice in vitro fertilization center. PATIENTS: A 36-year-old single gravida 0 presenting for oocyte cryopreservation on CHC. INTERVENTIONS: Discontinuation of vaginal ring combined hormonal contraceptive for 6 months. MAIN OUTCOME MEASURES: Antral follicle count, antimüllerian hormone, day 3 follicle-stimulating hormone, total oocytes, and mature oocytes retrieved before and after discontinuation of CHC. RESULTS: After a 6-month break from CHC, our patient's antimüllerian hormone level increased from undetectable levels to 3.45 ng/mL, day 3 follicle-stimulating hormone level decreased from 14.9 IU/mL-6.17 IU/mL, and antral follicle count improved from 0-28. In addition, the number of oocytes retrieved after a 4-month CHC break and 6-month break increased from 8 to 29, respectively. CONCLUSIONS: In patients on long-term combined continuous hormonal contraception, profound ovarian suppression can result in a clinical picture of diminished ovarian reserve and extremely poor response to high-dose stimulation, which may be reversed by more time off from suppression.

National survey on the opinions of French specialists in assisted reproductive technologies about social issues impacting the future revision of the French Bioethics laws.

INTRODUCTION: France is known for its conservative and unique position in assisted reproductive technologies (ARTs). At the eve of the future revision of French Bioethics laws, we decided to conduct a national survey to examine the opinions of French specialists in ARTs about social issues. MATERIAL AND METHODS: Descriptive study conducted in May 2017 in a university teaching hospital using an anonymous online questionnaire on current issues in ARTs. The questionnaire was sent by email to 650 French ARTs specialists, both clinicians and embryologists. RESULTS: After 3 reminders, 408 responses were collected resulting in a participation rate of 62.7% (408/650). Concerning pre-implantation genetic testing, 80% of the physicians were in favor of expanding the indications, which in France are presently limited to incurable genetic diseases. Authorizing elective Fertility Preservation was supported by 93.4% of the specialists, but without social coverage for 86.3% of them. Concerning gamete donation, 77.4% of the French ARTs specialists were in favor of giving a financial compensation to donors, 92% promoted preserving their anonymity and 80.9% were against a directed donation. ARTs for single heterosexual women were supported by 63.4% of the French specialists and by 72.5% for lesbian couples. The legalization of surrogacy was requested by 55.2%. DISCUSSION: Pending the revision of the French Bioethics laws, this survey provides an overview of the opinion of the specialists in ARTs on expanding ARTs for various social indications.Because of the evolution of social values, a more liberal and inclusive ART program is desired by the majority of ART specialists in France.
