RESUMO

BACKGROUND: Adolescence and young adulthood are critical life stages with varied healthcare needs. Adolescents and young adults (AYAs) are often confronted with challenges in their sexual and reproductive health (SRH) and rights. Uptake of SRH services among AYAs groups remains limited, especially in resource-limited settings. This could be partly attributed to the existing services not catering for the preferences of AYAs. However, there is no systematic evaluation of research to explore the preferences of AYAs for SRH services in Africa. Therefore, the objective of this systematic review is to assess AYAs's preferences for SRH in Africa. METHODS AND ANALYSIS: The systematic review will follow the recommendations of Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020. Stated preference studies in the area of SRH services conducted among AYAs will be included. We will search MEDLINE, EMBASE, PsycINFO, CINAHL, Scopus, Global Health and Google Scholar databases. Two independent researchers will screen the articles, and any disagreement will be handled through discussion with the broader research team. The quality of the included papers will be assessed and reported. The preferences for attributes, the most important and least important attributes and preference heterogeneity will be reported. In addition, the preference research gap across African regions and SRH services among AYAs will be reported. ETHICS AND DISSEMINATION: Ethical approval is not required for this protocol. The systematic review findings will be published in a peer-reviewed journal and presented at conferences. PROSPERO REGISTRATION NUMBER: CRD42023386944.

RESUMO

BACKGROUND: According to the WHO, obstetric fistula (OBF) is an abnormal connection between the genital tract and the urinary tract that occurs as the result of obstetric trauma, typically from prolonged obstructed labour. In 2018, globally, 50 000 and 100 000 cases of OBF are reported each year. The core of activities focused on reducing fistulas depends on a review of the disorder's knowledge and the features of women at risk of having a lack of understanding. The effect of community-level factors on awareness of OBF was not yet known in Nepal. Therefore, we aimed to investigate the community-level and individual-level factors of awareness of OBF among childbearing-aged women in Nepal. METHODS: The 2022 Nepal Demographic and Health Survey data were used for this study. It included 14 845 childbearing-aged women. Because of the clustering effects of Demographic and Health Survey data and the binary nature of the outcome variable, a multilevel binary logistic regression model was applied. An adjusted OR (AOR) with a 95% CI was reported to declare the statistical significance. In addition, the model that had the lowest deviance was the one that best fit the data. RESULTS: The overall prevalence of awareness of OBF among childbearing women in Nepal was 35.9% (95% CI 35.1%, 36.7%). Educational status (women who attended secondary education (AOR=1.65; 95% CI 1.41, 3.03) and higher education (AOR=4.29; 95% CI 1.14, 36.70)), currently working status (AOR=1.85; 95% CI 1.04, 3.30), birth history (AOR=2.23; 95% CI 1.48, 4.10), media exposure (AOR=1.54; 95% CI 1.07, 3.09) and women's age from 30 to 39 (AOR=3.38; 95% CI 1.35, 8.93) and 40 to 49 years old (AOR=4.68; 95% CI 1.60, 13.67) at the individual level, as well as urban residence (AOR=1.53; 95% CI 1.99, 2.87) and high community-level media exposure (AOR=2.05; 95% CI 1.67, 2.64) at the community level were statistically significant factors with awareness of OBF. CONCLUSION: Our study revealed that awareness of OBF among childbearing-aged women in Nepal was low (35.9%). The findings of this study will assist policymakers and public health programmers in understanding the magnitude of OBF awareness and the contributory factors. In addition, it will be useful to increasing awareness of OBF in the communities and promoting primary prevention approaches through education and motivation efforts.

RESUMO

A woman in her 30s presented to emergency with complaints of acute lower abdominal pain for 3 days, not associated with any menstrual, bowel or urinary symptoms. Examination revealed an abdominopelvic mass corresponding to an 18-week gravid uterus with diffuse tenderness and guarding over her lower abdomen. The patient was a follow-up case of subserosal fibroid uterus, chronic kidney disease stage 4 and rheumatic heart disease on anticoagulants. Fibroid degeneration or torsion was suspected. Ultrasound revealed a large posterior wall subserosal fibroid with free fluid in the pelvis. As findings did not suggest degeneration or pedunculated fibroid, noncontrast CT was done, which showed a similar mass with a pedicle arising from the uterine fundus with free fluid with no other evident cause of acute abdomen. The patient was taken up for emergency laparotomy. Intraoperatively, it was found to be a case of subserosal fibroid with greater omentum adhered to it and twisted around its axis about eight times. This case is being reported to highlight a rare cause of acute abdomen.

RESUMO

PURPOSE: To report an exceptional case of male-to-male transmission of genetically based non-obstructive azoospermia (NOA) and varicocele through a naturally obtained pregnancy. SUBJECTS AND METHODS: A father and his son were both diagnosed with NOA after centrifugation and varicocele. The father has no other clinical concerns apart from infertility, detected after many attempts of having another child, but given his urological situation (bilateral varicocele and NOA) assisted reproductive techniques were discouraged. After genetic counseling, several genetic-chromosomal analyses were carried out in the son (karyotype, chromosome Y microdeletions, CFTR screening, NGS infertility panels, and finally array-CGH). RESULTS: After a series of inconclusive tests, array-CGH detected a deletion of 224-283 kb (del9p24.3) involving part of the KANK1 and DMRT1 genes, inherited from the father. Haploinsufficiency of DMRT1 was therefore considered the determining factor in the development of azoospermia in the family by a loss of function mechanism. CONCLUSION: The confirmation of father-to-son transmission of a deletion including DMRT1 represents an important point for clinicians dealing with male infertility, even when complete azoospermia is repetitively detected, and must be of hope for a relevant portion of men. Inclusion criteria for the access to assisted reproductive techniques may also be reconsidered and worthy of a greater number of clinical insights. Finally, since DMRT1 alterations have been associated with NOA and abnormal testicular development, but not specifically with varicocele, further studies are required to validate this issue, as varicocele may have played a crucial role in this case.

RESUMO

A woman in her 20s was referred to a tertiary hospital emergency department for management of a migrating Implanon NXT. The Implanon was inserted 1 week prior by the patient's general practitioner who was unable to palpate the Implanon after insertion and hence, ordered an ultrasound scan which showed an actively migrating Implanon in the left basilic vein. She had mild chest pain, and her physical examination, ECG and blood tests were unremarkable. A CT chest showed a 31 mm foreign body within the right lower lobar artery. The foreign body was removed by interventional radiology by accessing the right internal jugular vein under ultrasound guidance and inserting a 6 FR pig catheter into the pulmonary trunk. The position was confirmed with angiogram and the foreign body was removed using a goose neck snare. The patient was discharged the same day with no complications, and fell pregnant a few months afterwards.

RESUMO

Background: Helicobacter pylori (H. pylori) causes sterility by affecting the reproductive system. Vitamin B12 improves sperm quantity and function. Objective: Vitamin B12 protection against H. pylori adverse effects was investigated. Materials and Methods: 40 C57 male mice (6 wk) were randomly assigned to 4 equal groups (n = 10) including, group 1 (control without any intervention), group 2 (H), 3 (HP), and 4 (HB) received 1 × 109 colony forming unit (CFU) of H. pylori, 1 × 109 CFU of H. pylori+phosphate buffered saline, 1 × 109 CFU of H. pylori+50 µ g/kg vitamin B 12 intraperitoneally, respectively. In the induction groups, the H. pylori was orogasterically injected 3 times with 1 cc phosphate buffered saline throughout the day. Then testicular metrics, sperm motility, viability, quantity, and shape, plasma levels of malondialdehyde (MDA), superoxide dismutase, glutathione peroxidase, and total antioxidant capacity were measured. Also, testicular-tissue changes were examined using Johnson scores, tubular differentiation index, and spermatogenesis index. Vitamin B12, homocysteine, and testosterone serum levels were examined. Results: The results showed a significantly lower Johnson score, tubular differentiation index, and spermatogenesis index, and serum level of testosterone and homocysteine as well as a higher MDA level in the H and HP groups than the HB group (p < 0.05). In contrast, the highest superoxide dismutase and glutathione peroxidase enzymes activity and total antioxidant capacity as well as the lowest serum level of MDA were found in the HB group compared to other groups (p < 0.05). Conclusion: Vitamin B 12 increased antioxidant enzyme activity, enhanced sperm parameters, and decreased injury to testicular tissue. It can be used as a potent antioxidant in reducing testicular damage induced by H. pylori.

RESUMO

Male subfertility or infertility is a common condition often characterized by men producing a low number of sperm with poor quality. To gain insight into this condition, we performed a quantitative proteomic analysis of semen samples obtained from infertile and fertile men. At least 6 proteins showed significant differences in regulation of alternatively spliced isoforms. To investigate this link between aberrant alternative splicing and production of poor-quality spermatozoa, we overexpressed the hnrnpH/F-orthologue Glorund (Glo) in Drosophila, which was also found to be abundant in poor quality human sperm. Transgenic animals produced low numbers of morphologically defective spermatozoa and aberrant formation of the "dense body," an organelle akin to the mammalian manchette. Furthermore, fertility trials demonstrated that transgenic flies were either completely infertile or highly subfertile. These findings suggest that dysregulation of hnrnpH/F is likely to result in the production of low-quality semen, leading to subfertility or infertility in men.

RESUMO

OBJECTIVES: This study aims to describe patterns of beliefs about contraceptive-induced infertility and assess their relationship with current contraceptive use, including whether these relationships vary by parity and residence. DESIGN: We use data from Performance Monitoring for Action Ethiopia, a nationally representative, cross-sectional survey of 7491 women, aged 15-49, to assess agreement with the statement 'If I use family planning, I may have trouble getting pregnant next time I want to.' We used multilevel hierarchical models to identify the association between agreement and use of a hormonal method of contraception among 3882 sexually active, fecund women who wish to prevent pregnancy. We include interaction terms for parity and residence. RESULTS: 4 in 10 women disagreed (42.3%) and 2 in 10 strongly disagreed (20.7%) with the statement. Relative to women who strongly disagreed, women who disagreed and women who agreed had significantly lower odds of using a hormonal method of contraception (adjusted OR (aOR) 0.65, 95% CI 0.44 to 0.97 and 0.46, 95% CI 0.46, 95% CI 0.30 to 0.70). The effect of agreeing with the statement was strongest among high parity women (aOR 0.54, 95% CI 0.30 to 0.95). Greater agreement with the statement at the community-level use was associated with a reduction in the odds of using hormonal contraception but only among rural women. CONCLUSIONS: Efforts to address concerns around contraceptive-induced fertility impairment through the provision of comprehensive counselling and through community education or mass media campaigns are necessary, particularly among high-parity women and in rural communities. Interventions should acknowledge the possibility of delayed return to fertility for specific methods and attempt to address the root causes of concerns.

RESUMO

BACKGROUND: Adequate literacy in reproductive and sexual health is essential for adolescents to obtain, comprehend, evaluate and apply information necessary for making well-informed decisions, as low literacy leads to harmful decision-making, risk-taking and poorer health and self-management. These factors increase the magnitude and severity of problems related to sexuality and reproduction, including unintended pregnancy, HIV/sexually transmitted infections, unsafe abortion and death. However, information regarding the status and affecting factors of literacy in the reproductive and sexual health of adolescents is scarce. OBJECTIVE: To assess reproductive and sexual health literacy status and associated factors among late-adolescent high school students. DESIGN: A cross-sectional, institution-based study. SETTING: The study included eight secondary schools in Arba Minch town (Gamo Zone) and three in Sawla town (Gofa Zone) in the South Ethiopia Region. METHODS: The study was done between 20 May and 20 June 2023, among late adolescent high school students. Using multistage sampling, 577 students were recruited. Reproductive health literacy was assessed using the Health Literacy Measure for Adolescents tool. Data were loaded into EpiData-V.3.1 and analysed using SPSS-V.25. Binary logistic regression analyses were used to identify associated factors. Variables with a p value <0.25 in bivariable logistic regression were candidates for multivariable logistic regression. A Hosmer-Lemeshow goodness-of-fit statistic was checked and satisfied. Statistical significance was indicated at a p value<0.05. RESULT: The proportion of students with limited reproductive and sexual health literacy was 69.6% (CI 65.3% to 72.8%). The limited literacy status was significantly associated with school type (public school AOR 0.28 (0.17 to 0.46)), mother's occupation (merchant AOR 0.42 (0.23 to 0.76)), family monthly income (income 10 000-20 000 birr AOR 0.45 (0.22 to 0.95)), having regular physical exercise >30 min (more than once per week, AOR 0.44 (0.23 to 0.84)), and knowledge about condoms (poor AOR 2.23 (1.38 to 3.64)). CONCLUSION: A notable segment of adolescents exhibited limited reproductive and sexual health literacy. The result emphasises the necessity of all relevant parties to work diligently to guarantee that school adolescents can easily obtain, comprehend, evaluate and use reproductive and sexuality-related information.

RESUMO

BACKGROUND: Many cancer treatments pose a threat to fertility for patients. Semen cryopreservation before cancer treatment is an effective method to preserve fertility. There are sparse long-term data on the usage of samples from Canadian oncology sperm banks. METHODS: A retrospective chart review of all oncology sperm banking samples at a Canadian academic fertility centre from 2001 to 2020 was conducted. RESULTS: From 2001 to 2020, 4521 samples were banked by 2504 patients. The most frequent diagnoses among these patients were testicular cancer (29.5%) and lymphoma (26.9%). Of these patients, only 81 (3.2%) patients returned to use their samples with intrauterine insemination (IUI) or in vitro fertilisation (IVF) treatment and 62 (2.5%) patients transferred their samples to another clinic. The time between banking and return for usage of the sperm ranged from 1 to 131 months with a median of 18 months after banking. A total of 66 IVF cycles (104 embryo transfers) and 101 IUI cycles from 67 patients were reviewed. Of the 67 couples who used their samples, 53.7% achieved a clinical pregnancy. The clinical pregnancy rate was 6.6% per cycle for IUI and 30.8% per embryo transfer for IVF. Higher sperm concentration or total motile count was not associated with a higher chance of pregnancy. Patients who conceived had on average 1.9 ± 0.8 (p=0.02) more usable embryos per cycle than those who did not conceive. CONCLUSIONS: Sperm cryopreservation provides a valuable option for patients with cancer to achieve parenthood after potentially gonadotoxic cancer treatment. However, the overall usage of banked oncology sperm samples is very low.

RESUMO

OBJECTIVE: This paper uses health economics methods to discuss the cost-effectiveness value of long protocol and antagonist protocol for in vitro fertilisation and embryo transfer (ET) in the Chinese population. DESIGN: Health economic evaluation study. SETTING: The data needed to construct the model for this study were derived from published studies and other secondary sources in China. PARTICIPANTS: No patients participated in the study. MEASURES: The main outcomes were live birth rate (LBR) and cost. From the societal perspective, we considered the direct and indirect costs over the course of the treatment cycles. A cost-effectiveness was measured using the incremental cost-effectiveness ratio and the probability that a protocol has higher net monetary benefit. Sensitivity analysis was carried out to verify the reliability of the simulation results. RESULTS: For the Chinese population, the long protocol resulted in a higher LBR than the antagonist protocol (29.33% vs 20.39%), but at the same time, it was more expensive (ï¿¥29 146.26 (US$4333.17) vs ï¿¥23 343.70 (US$3470.51)), in the case of considering only one fresh ET cycle. It was the same when considering subsequent frozen ET (FET) cycles (51.78% vs 42.81%; ï¿¥30 703.02 (US$4564.62) vs ï¿¥24 740.95 (US$3678.24)). The results of most subgroups were consistent with the results of the basic analysis. However, for certain populations, the long protocol was the inferior protocol (less effective and more expensive). CONCLUSION: For the Chinese population, when the monetary value per live birth was greater than ï¿¥65 420 (US$9726) and ï¿¥66 400 (US$9872), respectively, considering only one fresh cycle and considering subsequent frozen cycles, the long protocol is the preferred protocol. This threshold also varies for women of different ages and ovarian response capacities. For women in POSEIDON (Patient-Oriented Strategies Encompassing IndividualizeD Oocyte Number) group 2, group 3 and group 4, antagonist protocol is recommended as the preferred protocol. The results of this study need to be verified by further large-scale randomised controlled trials.

RESUMO

OBJECTIVES: Pregnancy outcomes of different ovarian stimulation protocols for in vitro fertilisation/intracytoplasmic sperm injection (IVF/ICSI) in patients with adenomyosis are not explicit. This meta-analysis aimed to systematically evaluate the effects of different IVF/ICSI protocols on pregnancy outcomes. DESIGN: Meta-analysis. DATA SOURCES: PubMed, Web of Science and Cochrane library were searched up to October 2023. ELIGIBILITY CRITERIA: Comparative studies on IVF/ICSI outcomes in the adenomyosis population were eligible. Studies on preimplantation genetic testing, reviews, case reports and animal experiments were excluded. DATA EXTRACTION AND SYNTHESIS: Valid information was extracted by two independent authors according to a standard data format. All analyses were conducted using Review Manager (RevMan, V.5.3). RESULTS: Compared with the non-adenomyosis population, adenomyosis was responsible for a 26% reduction in clinical pregnancy rate (CPR; 42.47% vs 55.89%, OR: 0.74, 95% CI: 0.66 to 0.82, p<0.00001), a 35% reduction in live birth rate (LBR; 30.72% vs 47.77%, OR: 0.65, 95% CI: 0.58 to 0.73, p<0.00001) and a 1.9-fold increase in miscarriage rate (MR; 27.82% vs 13.9%, OR: 1.90, 95% CI: 1.56 to 2.31, p<0.00001). Subgroup analysis suggested that, in fresh embryo transfer (ET) cycles, the CPR (34.4% vs 58.25%) in the long/short/antagonist protocol group was poorer than that in the ultralong protocol group. In frozen ET (FET) cycles, there were no statistical differences in CPR ((GnRHa+FET) AM(adenomyosis) vs non-AM: 51.32% vs 43.48%, p=0.31; (non-GnRHa+FET) AM vs non-AM: 50.25% vs 60.10%, p=0.82), MR ((GnRHa+FET) AM vs non-AM:12.82% vs 12.50%, p=0.97; (non-GnRHa+FET) AM vs non-AM: 30.5% vs 15.54%, p=0.15) and LBR ((GnRHa+FET) AM vs non-AM:44.74% vs 36.96%, p=0.31; (non-GnRHa+FET) AM vs non-AM: 34.42% vs 50.25%, p=0.28). The MR in the adenomyosis group was high in the fresh ET and FET cycles. CONCLUSIONS: FET might be a better choice for women with adenomyosis, especially those pretreated with GnRHa. In fresh ET cycles, pregnancy outcomes of the long/short/antagonist protocols were poorer than those of the ultralong protocol. TRIAL REGISTRATION NUMBER: CRD42022340743.

RESUMO

Male infertility is a major concern affecting reproductive health. Biallelic deleterious variants of most DNAH gene family members have been linked to male infertility, with intracytoplasmic sperm injection (ICSI) being an efficacious way to achieve offspring. However, the association between DNAH12 and male infertility is still limited. Here, we identified one homozygous variant and two compound heterozygous variants in DNAH12 from three infertile Chinese men. Semen analysis revealed severe asthenozoospermia, abnormal morphology, and structure of sperm flagella. Furthermore, the Dnah12 knock-out mouse revealed severe spermatogenesis failure and validated the same male infertility phenotype. Favorable fertility outcomes were achieved through ICSI in three human individuals and Dnah12 knock-out mice. Collectively, our study indicated that biallelic variants of DNAH12 can induce male infertility in both human beings and mice. Notably, evidence from DNAH12 enhanced that ICSI was an optimal intervention to achieve favorable fertility outcomes for infertile males with DNAH gene family variants.

RESUMO

Transverse vaginal septum (TVS) is a rare obstructive genital tract anomaly. It is associated with primary amenorrhoea and typically presents with cyclical abdominal pain due to obstruction of the menstrual flow. Caudal regression syndrome (CRS) is also a rare congenital anomaly that is frequently associated with anomalies of the neurological, musculoskeletal, cardiac, genitourinary and gastrointestinal systems. Obstructive genital tract anomaly in CRS is exceptionally rare. This report describes the case of a girl in early adolescence with underlying CRS who presented with severe abdominal pain associated with primary amenorrhoea. Clinical and radiological assessment revealed 'haematocolpos' manifesting as a tender 20 weeks' size abdominal mass and an absent vaginal opening. TVS was identified during examination under anaesthesia. The patient subsequently underwent a successful vaginoplasty with no recurrence of symptoms after 2 years.

RESUMO

The European Board and College of Obstetrics and Gynaecology (EBCOG) and the European Network of Trainees in Obstetrics and Gynaecology (ENTOG) express their concerns on the effect of climate change and environmental pollution. This paper reviews the impact on reproductive health and the contribution to climate change by the field of obstetrics and gynaecology. It concludes that its contributors and the effects of climate change cause definite adverse consequences to fertility and adverse obstetric outcomes. Mankind, and obstetrics and gynaecology personnel as well, must be aware and responsible of its contribution to climate change and consider the impact of their actions and interventions.

RESUMO

The Journal of Medical Ethics previously published on the debate in the UK and the Netherlands concerning the legal age limits imposed on donor-conceived people for access to information about the identity of gamete and embryo donors. In that publication, three arguments were foregrounded against lowering these age limits as a general rule for all donor-conceived people. In this contribution, we engage with these arguments and argue why we think they are insufficient to maintain the age limits. In contrast, we argue for a more suited, contextual and relational ethical framework based on care ethics, which emphasises relational autonomy and its dynamic, contextual development. This framework, we argue, provides a comprehensive approach for the analysis we made of the question of age limits and was applied in research performed in the Netherlands, commissioned by the Dutch Minister of Health. The framework enabled us to weigh the multidisciplinary-legal, psychological, phenomenological and ethical-findings of our research.

RESUMO

OBJECTIVE: We assessed the availability and readiness of health facilities to provide cervical cancer screening services in Nepal. DESIGN: Cross-sectional study. SETTING: We used secondary data from a nationally representative 2021 Nepal Health Facility Survey, specifically focusing on the facilities offering cervical cancer screening services. OUTCOME MEASURES: We defined the readiness of health facilities to provide cervical cancer screening services using the standard WHO service availability and readiness assessment manual. RESULTS: The overall readiness score was 59.1% (95% CI 55.4% to 62.8%), with more equipment and diagnostic tests available than staff and guidelines. Public hospitals (67.4%, 95% CI 63.0% to 71.7%) had the highest readiness levels. Compared with urban areas, health facilities in rural areas had lower readiness. The Sudurpashchim, Bagmati and Gandaki provinces had higher readiness levels (69.1%, 95% CI 57.7% to 80.5%; 60.1%, 95% CI 53.4% to 66.8%; and 62.5%, 95% CI 56.5% to 68.5%, respectively). Around 17% of facilities had trained providers and specific guidelines to follow while providing cervical cancer screening services. The basic healthcare centres (BHCCs) had lower readiness than private hospitals. Facility types, province and staff management meetings had heterogeneous associations with three conditional quantile scores. CONCLUSION: The availability of cervical cancer screening services is limited in Nepal, necessitating urgent action to expand coverage. Our findings suggest that efforts should focus on improving the readiness of existing facilities by providing training to healthcare workers and increasing access to guidelines. BHCCs and healthcare facilities in rural areas and Karnali province should be given priority to enhance their readiness.

RESUMO

Successful reproduction relies on the union of a single chromosomally normal egg and sperm. Chromosomally normal eggs develop from precursor cells, called oocytes, that have undergone accurate chromosome segregation. The process of chromosome segregation is governed by the oocyte spindle, a unique cytoskeletal machine that splits chromatin content of the meiotically dividing oocyte. The oocyte spindle develops and functions in an idiosyncratic process, which is vulnerable to genetic variation in spindle-associated proteins. Human genetic variants in several spindle-associated proteins are associated with poor clinical fertility outcomes, suggesting that heritable etiologies for oocyte dysfunction leading to infertility exist and that the spindle is a crux for female fertility. This chapter examines the mammalian oocyte spindle through the lens of human genetic variation, covering the genes TUBB8, TACC3, CEP120, AURKA, AURKC, AURKB, BUB1B, and CDC20. Specifically, it explores how patient-identified variants perturb spindle development and function, and it links these molecular changes in the oocyte to their cognate clinical consequences, such as oocyte maturation arrest, elevated egg aneuploidy, primary ovarian insufficiency, and recurrent pregnancy loss. This discussion demonstrates that small genetic errors in oocyte meiosis can result in remarkably far-ranging embryonic consequences, and thus reveals the importance of the oocyte's fine machinery in sustaining life.

RESUMO

Assisted reproductive technology (ART) has revolutionized the field of reproductive medicine, offering hope to millions of individuals and couples facing infertility challenges. In recent years, integrating robotics and artificial intelligence (AI) has emerged as a promising avenue for advancing ART. This comprehensive review explores the transformative impact of robotics and AI on ART, examining recent advancements, technological applications, clinical implications, and ethical considerations. Robotics enables precise and minimally invasive procedures, enhancing the efficiency and accuracy of various reproductive techniques such as sperm retrieval, embryo handling, and surgical interventions. Meanwhile, AI offers predictive analytics, personalized treatment protocols, and decision support systems tailored to individual patient needs, optimizing treatment outcomes and expanding access to reproductive care. Key findings highlight the significant advancements made possible by robotics and AI in ART, including improved success rates, reduced risks, and enhanced patient experience. However, challenges such as regulatory considerations, adoption barriers, and ethical dilemmas must be addressed to realize the full potential of these technologies. The transformative impact of robotics and AI on ART is profound, shaping the future of fertility treatment and family-building worldwide. Continued research, interdisciplinary collaboration, and investment are essential to further harness the potential of robotics and AI in advancing reproductive medicine and ensuring accessible, equitable, and effective care for all individuals and couples.

RESUMO

INTRODUCTION: Interventional clinical trials in recurrent miscarriage use varying expected effect sizes to inform their sample size calculations. Often these are not informed by what stakeholders consider a meaningful treatment effect. Adaptive trial designs may integrate stakeholder views on trial success and futility but the criteria to inform this is lacking. This study aims to understand relevant stakeholder views of what is considered a worthwhile treatment effect for miscarriage prevention interventions and what is acceptable stopping criteria in miscarriage clinical trials. METHODS AND ANALYSIS: The study is designed as a cross-sectional online anonymous survey. The survey presents different scenarios to respondents relating to varying target differences and probability thresholds and explores success and futility criteria for clinical trials. The survey was developed with personal and public involvement (PPI) through focus groups and a PPI partner. Eligible participants will be those with a personal history of miscarriage, including partners, and healthcare professionals who manage patients who experience a miscarriage. Convenience, snowball and purposive sampling techniques will be employed to invite eligible participants to complete the survey. The survey will be accepting responses for an initial 2-week pilot to check validity, prior to being open for a further 12 weeks. Descriptive analyses and linear regression analyses will synthesise the survey results. ETHICS AND DISSEMINATION: Ethical approval was obtained from the NHS Research Ethics Committee North West-Greater Manchester East (23/NW/0322) on 30 January 2024. Informed consent will be obtained prior to survey completion. No personal identifying information will be collected. The results will be published in a relevant scientific journal and communicated through our institutional website.
