RESUMEN
INTRODUCTION: This study aims to assess the motivations and treatment experiences of women undergoing social egg freezing and to understand the impact of the Covid-19 pandemic. MATERIAL AND METHODS: Between January 2011 to December 2021, 191 social egg freezing patients were recruited from the Lister Fertility Clinic, London UK. Participants completed a validated questionnaire investigating patients' perspectives of social egg freezing. A response rate of 46.6% was achieved. RESULTS: In all, 93.9% of women expressed concern regarding age-related fertility decline which influenced their decision to undergo social egg freezing. The majority (89.5%) of women were not in a relationship at the time of social egg freezing and considered this a motivating factor. Also, 39.0% of participants had side effects related to treatment which affected work and social life. Participants were significantly more likely to experience side effects if they underwent multiple egg freezing cycles (χ2 , p < 0.01) or if they cryopreserved oocytes during the COVID-19 pandemic (χ2 , p < 0.05). Of the women, 64.0% wished to have cryopreserved oocytes at a younger age, a view significantly more likely if older than 37 years at first social egg freezing cycle (χ2 , p < 0.001). Also, 82.3% of women reported their decision to undergo social egg freezing was not delayed due to concerns regarding COVID-19 exposure during treatment; 44.1% considered the pandemic made them more willing to undergo social egg freezing. CONCLUSIONS: Most participants did not regret their decision to undergo social egg freezing but the majority wished they had cryopreserved oocytes at a younger age. This highlights the importance of early education to optimize outcomes and patient choice. The egg freezing process can be stressful, women may have concerns around social egg freezing and unprecedented situations such as the COVID-19 pandemic may alter treatment experience.

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.

Infertility affects more than 14% of couples, 30% being caused by male factor infertility. This meta-analysis includes 28 studies, selected according to PRISMA guidelines. Data were extracted from these studies to collate cycles separating paternal age at 30, 35, 40, 45 and 50 years (±1 year). Primary outcomes of interest were clinical pregnancy, live birth and miscarriage rates. Secondary outcomes were the number of fertilized eggs, cleavage-stage embryos and blastocysts, and embryo quality per cycle. Fixed-effects and random-effects models giving pooled odds ratios (OR) were used to assess the effect of paternal age. This meta-analysis included a total 32,484 cycles from 16 autologous oocyte studies and 12 donor oocyte studies. In autologous cycles, a statistically significant effect of paternal age <40 years was noted in clinical pregnancy (OR 1.65, 95% confidence interval [CI] 1.27-2.15), live birth (OR 2.10, 95% CI 1.25-3.51) and miscarriage (OR 0.74, 95% CI 0.57-0.94) rates. Paternal age <50 years significantly reduced miscarriage rate (OR 0.68, 95% CI 0.54-0.86), and increased blastocyst rate (OR 1.61, 95% CI 1.08-2.38) and number of cleavage-stage embryos (OR 1.67, 95% CI 1.02-2.75) in donor oocyte cycles, where maternal age is controlled. This is an important public and societal health message highlighting the need to also consider paternal age alongside maternal age when planning a family.

Uterine transplantation has evolved rapidly over the last decade. As the number of cases performed increases exponentially worldwide, emerging evidence continues to improve collective knowledge and understanding of the procedure, with the aim of improving both surgical and reproductive outcomes. Although currently restricted to women with absolute uterine factor infertility, increasing awareness as a method of fertility restoration has resulted in a demand for the procedure to be undertaken in transgender women. This manuscript summarizes the recent advances in uterine transplantation, and elaborates further upon the key novel avenues research within the field will focus on over the coming years.

STUDY QUESTION: What are the knowledge and views of UK-based women towards egg donation (ED) and egg sharing (ES)? SUMMARY ANSWER: Lacking knowledge of the practices of ED and ES could be an influential factor in donor egg shortages, rather than negative perceptions or lack of donor anonymity and financial incentives. WHAT IS KNOWN ALREADY: The increasing age of women trying to conceive has led to donor egg shortages, with ED and ES failing to meet demand. Indeed, in recent years in the UK, ES numbers have fallen. This results in long waiting lists, forcing patients abroad for fertility treatment to take up cross border reproductive care. Previous research suggests a lack of knowledge of ED among members of the general public; however, no study has yet assessed knowledge or views of ES in the general public. STUDY DESIGN, SIZE, DURATION: Six hundred and thirty-five UK-based women over 18 years were voluntarily recruited from social media community groups by convenience sampling. The recruitment period was from February to April 2020. PARTICIPANTS/MATERIALS, SETTING, METHODS: Participants completed a previously validated questionnaire regarding female fertility, ED and ES, including knowledge, perceptions and approval of the practices and relevant legislation. This included ranking key benefits and issues regarding egg sharing. The questionnaire was completed using the online Qualtrics survey software. Statistical analysis was conducted using SPSS. MAIN RESULTS AND THE ROLE OF CHANCE: Regarding knowledge of ED and ES, 56.3% and 79.8%, respectively had little or no prior knowledge. Upon explanation, most approved of ED (85.8%) and ES (70.4%). A greater proportion of respondents would donate to a family member/friend (49.75%) than to an anonymous recipient (35.80%). Overall, ES was viewed less favourably than ED, with ethical and practical concerns highlighted. Women aged 18-30 years were significantly more likely to approve of egg donation practice compared to those aged >30 years (P < 0.0001). Those against ES found fears of financial coercion or negative psychological wellbeing the most concerning. About 35.8% and 49.7% would personally consider anonymous and known ED, respectively, whilst 56.7% would consider ES. Those answering in favour of egg sharing were significantly more likely to give higher benefit ratings compared to those against the practice (P < 0.001). Most agreed (55.8%) with and were not deterred to donate (60.1%) by the 'Disclosure of Donor Identity' legislation. Only 31.6% agreed with the compensatory cap; however, 52.7% would not be more motivated to donate by an increased cap. LIMITATIONS, REASONS FOR CAUTION: There were several limitations of the study, including the use of convenience sampling and the voluntary nature of participation opening the study up to sampling and participation bias. Finally, closed questions were predominantly used to allow the generation of quantitative data and statistical analysis. However, this approach prevented opinion justification and qualitative analysis, limiting the depth of conclusions drawn. WIDER IMPLICATIONS OF THE FINDINGS: To our knowledge, this is the first study to survey the general public's knowledge and views of ED/ES using a previously validated questionnaire. The conclusion that lack of knowledge could be contributing to the current donor shortfall in the UK demonstrates that campaigns to inform women of the practices are necessary to alleviate donor oocyte shortages. STUDY FUNDING/COMPETING INTEREST(S): No external funds were used for this study. The authors have no conflicts of interest. TRIAL REGISTRATION NUMBER: NA.

STUDY QUESTION: Does fertility treatment (FT) significantly increase the incidence of breast, ovarian, endometrial or cervical cancer? SUMMARY ANSWER: Overall, FT does not significantly increase the incidence of breast, ovarian or endometrial cancer and may even reduce the incidence of cervical cancer. WHAT IS KNOWN ALREADY: Infertility affects more than 14% of couples. Infertility and nulliparity are established risk factors for endometrial, ovarian and breast cancer, yet the association with FT is more contentious. STUDY DESIGN, SIZE, DURATION: A literature search was carried out using Cochrane Library, EMBASE, Medline and Google Scholar up to December 2019. Peer-reviewed studies stating cancer incidence (breast, ovarian, endometrial or cervical) in FT and no-FT groups were identified. Out of 128 studies identified, 29 retrospective studies fulfilled the criteria and were included (n = 21 070 337). PARTICIPANTS/MATERIALS, SETTING, METHODS: In the final meta-analysis, 29 studies were included: breast (n = 19), ovarian (n = 19), endometrial (n = 15) and cervical (n = 13), 17 studies involved multiple cancer types and so were included in each individual cancer meta-analysis. Primary outcome of interest was cancer incidence (breast, ovarian, endometrial and cervical) in FT and no-FT groups. Secondary outcome was cancer incidence according to specific fertility drug exposure. Odds ratio (OR) and random effects model were used to demonstrate treatment effect and calculate pooled treatment effect, respectively. A meta-regression and eight sub-group analyses were performed to assess the impact of the following variables, maternal age, infertility, study size, outliers and specific FT sub-types, on cancer incidence. MAIN RESULTS AND THE ROLE OF CHANCE: Cervical cancer incidence was significantly lower in the FT group compared with the no-FT group: OR 0.68 (95% CI 0.46-0.99). The incidences of breast (OR 0.86; 95% CI 0.73-1.01) and endometrial (OR 1.28; 95% CI 0.92-1.79) cancers were not found to be significantly different between the FT and no-FT groups. Whilst overall ovarian cancer incidence was not significantly different between the FT and no-FT groups (OR 1.19; 95% CI 0.98-1.46), separate analysis of borderline ovarian tumours (BOT) revealed a significant association (OR 1.69; 95% CI 1.27-2.25). In further sub-group analyses, ovarian cancer incidence was shown to be significantly higher in the IVF (OR 1.32; 95% CI 1.03-1.69) and clomiphene citrate (CC) treatment group (OR 1.40; 95% CI 1.10-1.77), respectively when compared with the no-FT group. Conversely, the incidences of breast (OR 0.75; 95% CI 0.61-0.92) and cervical cancer (OR 0.58; 95% CI 0.38-0.89) were significantly lower in the IVF treatment sub-group compared to the no-FT group. LIMITATIONS, REASONS FOR CAUTION: The large, varied dataset spanning a wide study period introduced significant clinical heterogeneity. Thus, results have to be interpreted with an element of caution. Exclusion of non-English citations, unpublished work and abstracts, in order to ensure data accuracy and reliability was maintained, may have introduced a degree of selection bias. WIDER IMPLICATIONS OF THE FINDINGS: The results for breast, ovarian, endometrial and cervical cancer are reassuring, in line with previously published meta-analyses for individual cancers but the association between IVF and CC treatment and an increase in ovarian cancer incidence requires additional work to understand the potential mechanism driving this association. In particular, focusing on (i) discriminating specific treatments effects from an inherent risk of malignancy; (ii) differential risk profiles among specific patient sub-groups (refractory treatment and obesity); and (iii) understanding the impact of FT outcomes on cancer incidence. STUDY FUNDING/COMPETING INTEREST(S): This study did not receive any funding. The authors have no financial, personal, intellectual and professional conflicts of interest to declare.

Metabolomics, the global analysis of metabolites in a biological specimen, could potentially provide a fast method of biomarker identification for ovarian cancer. This systematic review aims to examine findings from studies that apply metabolomics to the diagnosis, prognosis, treatment, and recurrence of ovarian cancer. A systematic search of English language publications was conducted on PubMed, Science Direct, and SciFinder. It was augmented by a snowball strategy, whereby further relevant studies are identified from reference lists of included studies. Studies in humans with ovarian cancer which focus on metabolomics of biofluids and tumor tissue were included. No restriction was placed on the time of publication. A separate review of targeted metabolomic studies was conducted for completion. Qualitative data were summarized in a comprehensive table. The studies were assessed for quality and risk of bias using the ROBINS-I tool. 32 global studies were included in the main systematic review. Most studies applied metabolomics to diagnosing ovarian cancer, within which the most frequently reported metabolite changes were a down-regulation of phospholipids and amino acids: histidine, citrulline, alanine, and methionine. Dysregulated phospholipid metabolism was also reported in the separately reviewed 18 targeted studies. Generally, combinations of more than one significant metabolite as a panel, in different studies, achieved a higher sensitivity and specificity for diagnosis than a single metabolite; for example, combinations of different phospholipids. Widespread metabolite differences were observed in studies examining prognosis, treatment, and recurrence, and limited conclusions could be drawn. Cellular processes of proliferation and invasion may be reflected in metabolic changes present in poor prognosis and recurrence. For example, lower levels of lysine, with increased cell invasion as an underlying mechanism, or glutamine dependency of rapidly proliferating cancer cells. In conclusion, this review highlights potential metabolites and biochemical pathways which may aid the clinical care of ovarian cancer if further validated.

INTRODUCTION: Women are postponing childbearing and preventing age-related fertility decline with oocyte freezing for non-medical reasons (OFNMR). The objective of this systematic evaluation was to gain an understanding of women's attitudes and knowledge of, and intentions to use OFNMR among users of OFNMR and the general public. MATERIAL AND METHODS: A systematic search of MEDLINE, EMBASE, and PyschINFO databases was undertaken, for studies that examined the psychosocial attitudes among women toward OFNMR. The search was limited to English language and no time restriction was set for publications. Extracted data were analyzed using thematic analysis and the study was performed according to PRISMA guidelines with prospective PROSPERO registration (CRD4201912578). RESULTS: Overall, 35 studies met the inclusion criteria. Studies were broadly categorized into studies investigating users or potential users of OFNMR, and studies examining the views of members of the general public. Users of OFNMR have good knowledge of age-related fertility decline and awareness of the OFNMR procedure. Lack of partner was identified as the most common motivating factor to undertake OFNMR, with cost as a predominant concern. Knowledge among the general public of OFNMR is highly variable. Underestimation of age-related fertility decline is common among the general public. Intentions of women to use OFNMR also varied drastically between studies. CONCLUSIONS: Women are predominantly motivated to freeze eggs by the lack of a suitable partner, but cost is a significant barrier. Increasing the number of women pursuing OFNMR at an earlier stage may positively impact upon the risk of future involuntary childlessness. Better information should be made available to both women and men about their fertility and options to inform their reproductive decision-making.

INTRODUCTION: Pre-implantation genetic testing for aneuploidy (PGT-A) is in high demand worldwide, with ongoing debate among medical societies as to which patient groups it should be offered. The psychological aspects for patients regarding its use, lag behind the genomic technological advances, leaving couples with limited decision-making support. The development of this technology also leads to the possibility for its utilization in gender selection. Despite the controversy surrounding these issues, very few studies have investigated the psychological aspects of patients using PGT-A. MATERIAL AND METHODS: This systematic review provides an up-to-date analysis of the psychosocial aspects surrounding PGT for aneuploidy and sex selection, as well as decision-making factors. A systematic search of English peer-reviewed journals of three computerized databases were undertaken following PRISMA guidelines. The qualitative data were extracted using thematic analysis. PROSPERO Registration number: CRD42019126439. RESULTS: The main outcome measures were patients' motivations, decision-making factors, attitudes and experiences surrounding the use of PGT for aneuploidy and sex selection. Ten studies were included, four for PGT-A and six for sex selection. Attitudes towards PGT-A were positive, with the main motivating factors being decreasing miscarriage rate, reducing the risk of termination of pregnancy and reducing the time to pregnancy. Consistently raised concerns regarding PGT-A were the financial burden and moral beliefs. The vast majority of patients felt sufficiently knowledgeable to make the decision; however, studies did reveal that a minority mis-interpreted certain potential benefits of PGT-A. Studies investigating PGT for sex selection predominantly reported the main motivation was to achieve gender balance within the family dynamic, with most studies finding no difference between couples using PGT for gender selection to have male or female offspring. CONCLUSIONS: Although this systematic review was limited by the small number of studies investigating this topic, a significant minority of patients appeared to misunderstand certain benefits and limitations of PGT-A. Fertility clinics must ensure they provide adequate counseling to all patients using PGT-A. With the use of PGT-A on the rise globally, there is a need to develop decision support tools for couples who have an increasing number of genetic testing options becoming available to them.

PURPOSE: Pre-implantation genetic testing for aneuploidies (PGT-A) is a technique used as part of in vitro fertilisation to improve outcomes. Despite the upward trend in women utilising PGT-A, data on women's motivations and concerns toward using the technology, and perceptions having undergone the process, remain scarce. METHODS: This cross-sectional survey, based at a fertility clinic in the UK, utilised an electronic questionnaire to assess the motivations of women who undergo PGT-A and their perceptions and attitudes toward PGT-A after using it. RESULTS: One hundred sixty-one women responded. The most significant motivating factors to undergo PGT-A were to improve the probability of having a baby per cycle (9.0 ± 2.1) and enhance the chance of implantation (8.8 ± 2.5). The least important motivations were reducing the number of embryos transferred per cycle (2.7 ± 3.3) and saving money by reducing the number of procedures required (4.6 ± 3.4). The most significant concerning factors identified included not having embryos to transfer (5.7 ± 3.4) and the potential for embryo damage (5.2 ± 3.3). The least concerning factors included religious (0.6 ± 1.7) or moral (1 ± 2.2) concerns. The majority of women were satisfied/very satisfied following treatment (n = 109; 68%). The proportion of those who were satisfied/very satisfied increased to 94.2% (n = 81) following a successful outcome, and reduced to 43.5% (n = 27) in those who had an unsuccessful outcome or had not undergone embryo transfer (p < 0.001). CONCLUSION: This study highlights that perceptions amongst women who use PGT-A are mostly positive. We also demonstrate a significant association between satisfaction and reproductive outcomes, with those who achieve a live birth reporting more positive perceptions toward PGT-A.

INTRODUCTION: Social egg freezing enhances reproductive autonomy by empowering women with the capacity to delay their childbearing years, while preserving the opportunity to maintain biological relation with subsequent offspring. However, age-related obstetric complications, economic implications and the risk of unsuccessful future treatment make it a controversial option. Despite the upward trend in women electively cryopreserving their eggs, there is limited data about the women's perceptions, having undergone the process. The aim of this study was to investigate the motivations of women who have undergone social egg freezing, identify their perceptions following treatment, and assess potential feelings of regret. MATERIAL AND METHODS: This cross-sectional survey, based at a fertility clinic in the UK, used an electronic questionnaire to assess the motivations and perceptions of women who underwent social egg freezing between 1 January 2008 and 31 December 2018. RESULTS: One hundred questionnaires were distributed, and 85 women responded (85% response rate). The most frequent reason for freezing oocytes was not having a partner with 56 (70%) women saying it "definitely" influenced their decision. The majority of women (83%; n = 68) knew there was a chance of treatment failure in the future and that a live birth could not be guaranteed. More than half (n = 39; 51%) disagreed or strongly disagreed that the 10-year UK storage limit is fair. One-third of respondents (n = 17; 33%) felt the storage time should be indefinite and 29% (n = 15) believed it should be up to the age of 50. Twenty percent (n = 15) of the women who underwent social egg freezing have successfully had a baby or are currently pregnant, half (n = 8; 53%) of whom conceived spontaneously and a quarter (n = 4; 26%) used their stored oocytes. In all, 91% (n = 73) had no regrets over their decision to undergo social egg freezing. CONCLUSIONS: We demonstrate herein important and novel insights into the motivations and perceptions of women from a UK population who have undergone social egg freezing. Despite potential physical, psychological, and financial burdens, only a small minority of women experience regret after social egg freezing. We also highlight clear discontent with the Human Fertilisation & Embryology Authority storage limit among social egg freezers in the UK.

CONTEXT: Uterine transplantation (UTx). OBJECTIVE: To explore patients' knowledge of and attitudes toward UTx before and after a short educational intervention via a video and question and answer (Q&A) session. DESIGN: Large, in-depth survey investigating patients' motivations, aims, and beliefs on UTx. SETTING: Imperial College London. PARTICIPANTS: Women diagnosed with absolute uterine factor infertility (AUFI) who were seeking information on UTx and had already volunteered to participate in the study. INTERVENTION: A semistructured interview involving a brief baseline questionnaire before a Q&A session and a 20-minute video exploring the main risks and benefits for UTx. MAIN OUTCOME MEASURES: Attitudes of self-referred patients with AUFI toward UTx before and after education focusing on UTx. Rank order of importance of key UTx-related issues. RESULTS: Forty women were interviewed. Following the video presentation and Q&A session, 97.5% (n = 39) would undergo UTx ahead of surrogacy and adoption in full knowledge that the latter 2 options would be ultimately safer for their own well-being and the fact that the graft could fail even prior to conception. All felt that UTx should take place, and 92.5% saw UTx as achievable. CONCLUSION: The study demonstrates a keen interest in UTx, partly because other options seem difficult to access. It is worth noting that people appear to be distancing themselves from the risk. This requires careful assessment in any clinical program. This study is the first to demonstrate a qualitative relationship between patients with AUFI and their curiosity and desire for UTx. It paves the way for forming the introduction into the psychological assessment of a potential patient.

CONTEXT: Currently, the only 2 options that women with absolute uterine factor infertility have for managing their infertility are surragocy or adoption. These women may also benefit from a possible future third option: uterine transplant. OBJECTIVE: To investigate the opinions and views of UK health care professionals toward uterine transplant and rank issues related to uterine transplant by importance in order to make uterine transplant transparent and understandable to colleagues. DESIGN: Large, in-depth survey investigating health care professionals' opinions on uterine transplant. SETTING: Analysis done at Imperial College London. PARTICIPANTS: UK transplant professionals (surgeons, nurses, operating room staff, and donor coordinators) and obstetricians and gynecologists (trainees, members, and fellows of the Royal College of Obstetricians and Gynaecologists). INTERVENTION: Questionnaires were given out at hospital grand rounds, trainee teaching days, and conferences (national and international). MAIN OUTCOME MEASURES: Should uterine transplant take place? Is uterine transplant achievable? What is the rank order of importance of key issues related to uterine transplant? RESULTS: The study had 528 participants. With respect to overall support for uterine transplant and as a possible future therapeutic option for absolute uterine factor infertility, 93.8% (n=495) thought that uterine transplant should take place if considered appropriate medically, surgically, and ethically and 57.2% (n=302) thought it was an achievable objective. Issues related to immunology of uterine transplant and pregnancy after uterine transplant were unanimously thought of as most important. More effort is required to educate health care professionals about all aspects of uterine transplant.

This review explores the impact of polyunsaturated fatty acid (PUFA) supplementation in women undergoing assisted reproductive technology (ART) on reproductive outcomes. A systematic search of English peer-reviewed journals was carried out using MEDLINE, EMBASE, and the Cochrane Library to identify articles published from January 1978 to 2021. The primary outcomes assessed included pregnancy and live birth rates. Secondary outcome measures included: (i) implantation rate; (ii) fertilisation rate; (iii) number of oocytes retrieved; (iv) number of metaphase II (MII) oocytes; (v) blastocyst conversion; and (vi) embryo quality. A total of 4 randomised control trials (RCTs) met the inclusion criteria. There is a lack of high-quality research to support widespread dietary supplementation with PUFAs in women undergoing ART. Prior to its clinical recommendation, there is a need for well-designed RCTs to facilitate an in-depth understanding of PUFA supplementation in women undergoing ART.
RESUMEN
This study aimed to discover whether egg sharing compromises the chance of donors or recipients achieving a live birth. A descriptive cohort study was performed of 4,545 fertility patients and 5,316 stimulation cycles at a London based fertility clinic between 2010 and 2019. There was no significant difference in clinical pregnancy rate (CPR) or live birth rate (LBR) between egg sharers and standard IVF patients or between egg sharing recipients and non-egg sharing recipients. Both egg sharers and their recipients had fewer oocytes and fewer day 3 embryos available for fresh embryo transfer or cryopreservation than standard IVF patients or non-egg sharing recipients. The cumulative LBR were significantly lower amongst egg sharers than standard IVF patients (p < 0.05), and significantly lower amongst egg sharing recipients than non-egg sharing recipients (p < 0.05). This study demonstrates that egg sharing does not compromise the chances of donors or their recipients achieving a live birth. However, participants may occasionally require additional ovarian stimulation cycles to conceive. With government funding for IVF treatment falling, egg sharing provides a practical option to allow more women access to IVF. Egg sharing is currently the most efficient way of maximising the use of the precious resource of human oocytes.

Medical care for transgender people is multi-faceted and attention to individual reproductive aspirations and planning are an essential, yet often overlooked aspect of care. Given the impact of hormonal therapy and other gender affirmation procedures on reproductive function, extensive counselling and consideration of fertility preservation is recommended prior to their commencement. This review article explores the reproductive aspirations of transgender women and considers the current disparity between stated desires regarding utilisation of fertility preservation services. Current fertility preservation options and prospective treatments currently showing promise in the research arena are explored.
RESUMEN
IMPORTANCE: The study summarises the selection prescreen criteria currently used in the UK for a uterus transplant and highlights the number of women who are suitable to proceed. OBJECTIVES: To assess the demographics, motivations, reasons and suitability among women with absolute uterine factor infertility (AUFI) to undergo uterine transplantation (UTx). DESIGN: A cross-sectional survey. SETTING: An electronic questionnaire was sent via email to women with AUFI who had previously been referred to the UTx research team or approached the Womb Transplant UK Charity. The questions assessed suitability to undergo UTx based on demographic information, perceptions to adoption and surrogacy and reasons why UTx was preferable. Responses were assessed against the study selection criteria. PARTICIPANTS: Women with AUFI. RESULTS: 210 women completed the questionnaire. The most common aetiology of AUFI in our cohort was Mayer-Rokitansky-Küster-Hauser (68%; n=143) whereas 29% (n=62) had previously undergone hysterectomy. 63% (n=132) of the cohort had previously considered adoption, 5% (n=11) had attempted it and 2 (1%) had successfully adopted. The most common reason cited to undergo UTx over adoption was to experience gestation (n=63; 53%), while 37% (n=44) wanted a biologically related child. 76% (n=160) of participants had previously considered surrogacy, 22 (10%) had attempted it and 2 (1%) had successfully become mothers using a surrogate. The most common reason to undergo UTx over surrogacy was to experience gestation (n=77; 54%). 15% (n=21) were concerned about the legal implications, 14% (n=20) identified the financial cost as a barrier and 8% (n=12) could not consider it due to religious reasons. On adhering to the selection criteria, 65 (31%) women were suitable to proceed with the trial. CONCLUSION: The study demonstrates that implementing commonly used selection criteria for a UTx led to an attrition rate of more than two-thirds of women who requested to initially undergo the process. As more studies present outcomes following UTx, critical assessment of the selection criteria currently used is warranted to ensure potential recipients are not being unnecessarily excluded.
