RESUMEN
Background: Infertility along with fertility treatments has been reported to have a devastating effect on the well-being of the individuals involved as well as their relationship. So far, the studies exploring the impact on the relationship have mainly focused on heterosexual couples facing infertility and undergoing treatment. There is, therefore, a lack of data on the potential role of sexual orientation, gamete origin, as well as treatment success on the risk of separation after fertility treatment. The purpose of this study was, thus, to explore whether sexual orientation, donation treatment, and fertility success affected the relationship well-being and to explore various separation-related aspects. Methods: We have performed a prospective cohort study of heterosexual and homosexual couples undergoing fertility treatment with autologous and donated gametes in Sweden and followed them for up to 10 years after receiving fertility treatment. In the current follow-up study, 660 individuals have been included. Results: Almost 39% of lesbian couples participating reported having separated as opposed to 11-17% of heterosexual couples undergoing treatment with own or donated gametes. Neither background factors nor treatment success protected against separation. By using the relationship satisfaction ENRICH tool, we were able to demonstrate that dissatisfaction of one of the lesbian spouses or heterosexual spouses undergoing oocyte donation increased significantly the risk of separation 8-10 years after treatment commencement. Conclusion: The findings can be used by fertility clinics to provide relationship tools to the treated couples in order to help them nurture their relationship and decrease the risk of separation in the long run.

BACKGROUND: Fertility centre websites are a key sources of information on medically assisted reproduction (MAR) for both infertile people and the general public. As part of a global fertility market, they are also a window to attract potential future patients. They give formal and practical information but in the way the information is displayed, they also convey social representations, and in particular, gender representation in its intersectional dimension. The objective is to analyse the sex, class and race representations regarding reproduction and parenthood that are embedded in the content of fertility centre websites in eight European countries. METHODS: The 5 most visible fertility centres that appeared in the first places on Internet search were selected for each country under study, except for one country which has only three fertility centres. In total, 38 fertility centre websites were considered for a thematic analysis using an iterative approach and a comprehensive perspective. RESULTS: Each centre details its services and techniques according to the legal provisions in force in its country. However, on all the websites studied, the fertility centres demonstrate a strong gendered representation. The logos generally depict women or parts of their bodies, as do the photos, which mainly show white women with light eyes. The description of the causes of infertility and the techniques offered by the centres also highlights gender differences. Sperm donation, where MAR is reserved for heterosexual couples, is included among the techniques for women with the comment that it will enable them to fulfil their dream of becoming mothers. CONCLUSIONS: MAR, and through it the project of having a child and procreative work, is presented as a matter for white, cisgender and heterosexual women, thus fueling stratified reproduction and limiting reproductive justice. The research team formulated guidelines for fertility centres to encourage them to adopt a more inclusive approach in terms of sex, social class and race, so that the diversity of infertile people feel involved and welcome in these centres, to avoid misperceptions about infertility in the general population and to reinforce autonomy and justice in reproductive matters.
Fertility centre websites are a key sources of information on medically assisted reproduction (MAR) for both people undergoing MAR and the general public.

Objectives: Thyroid dysfunction is commonly associated with the risk of infertility in both females and males. However, recent randomized controlled trials have demonstrated that thyroid function levels in females are not significantly related to infertility, and evidence on the association between male thyroid function and infertility is limited. We aim to investigate the association between thyroid function levels and infertility in both females and males. Method: A two-sample Mendelian randomization study was conducted using four methods, with the inverse variance weighted method (IVW) as the primary approach. Data on thyroid function as the exposure were obtained from the ThyroidOmics Consortium and UK Biobank, including over 700,000 individuals from a large meta-analysis of genome-wide association studies for thyroid function and dysfunction. The outcome data for infertility in both sex encompassed more than 70,000 individuals from the FinnGen Consortium. All participants were adults of European ancestry. The MR Egger regression intercept and Cochran's Q test were employed to evaluate directional pleiotropy and heterogeneity. Results: The results indicated no causal effect of thyroid-stimulating hormone (TSH) and free tetraiodothyronine (fT4) on female and male infertility. Furthermore, no causal association between hypo- and hyperthyroidism and infertility were identified. Notably, we observed a causal relationship between high TSH and endometriosis-related infertility (OR=0.82, 95% CI: 0.74-0.91, P = 1.49E-04). Conclusions: This study did not find evidence for casual relationship between thyroid function levels and risk of infertility. The findings suggest that overall thyroid function levels may not be a significant predictor of infertility risk.

BACKGROUND: Today, idiopathic infertility is becoming more frequent, affecting more than 186 million people in the world. The presence of comorbidities makes patient management complex, requiring individualized infertility treatment. Periodontal diseases could contribute negatively to the management of infertility, increasing inflammation, oxidative stress and insulin resistance, and contributing negatively to the development and progression of comorbidities associated with these two entities. The aim of this systematic review is to explore whether there is an association between periodontal diseases and male and female infertility and deepen into the possible mechanisms underlying this association. MATERIAL AND METHODS: The studies analyzed in this research included a total of 4871 patients (732 men and 4139 women), were original studies with high quality, mostly with a control group. Authors who have investigated idiopathic infertility suggest that infertility is associated with diseases that present low-grade chronic inflammation, oxidative stress and insulin resistance (such as obesity, type 2 diabetes and polycystic ovary syndrome), which are in turn related to periodontal diseases. RESULTS: A higher prevalence of periodontal disease was found in patients with infertility compared with controls. Periodontal diseases could initially be mediated by a local and systemic proinflammatory environment, which favors a pro-oxidant state, leading to oxidative stress and, finally, irreversible destruction of the periodontal tissue. Insulin resistance, oxidative stress and inflammation are present in the pathologies associated with an increase in the prevalence and severity of periodontal diseases (such as obesity, type 2 diabetes and polycystic ovary syndrome). Therefore, IR, low-grade chronic inflammation and the oxidative stress could be the pathophysiological mechanisms linking idiopathic infertility and periodontal diseases. CONCLUSIONS: Studies suggest an association between infertility and periodontitis. Future researches are necessary to find causality factors. Studying the patient in a global and multidisciplinary way could help in the management and treatment of idiopathic infertility.

Infertility, affecting approximately 16% of the global population, has led to increased reliance on reproductive medicine. The impact of human papillomavirus (HPV) infection in one or both partners on outcomes of Assisted Reproduction Technologies (ART) remains unclear. This prospective cohort study aimed to evaluate prevalence and effects of HPV infection in subjects and couples candidates to ART. A total of n = 510 men and n = 246 women were included and n = 145 couples (n = 290 individuals) had both partners enrolled in the study. The HPV semen infection rate was 17% (95% CI: 14-20) with HPV-42, HPV-16, HPV-53 and HPV-51 as the most frequently detected genotypes. In women, 26% (95% CI: 21-32) tested HPV-positive in cervical swabs. In 6% (95% CI: 3-11) of the couples, both partners were positive but only three couples shared the same genotypes (HPV-16; HPV-39, HPV-51, and HPV-42; HPV-31). Follicular fluids were positive in 20% (95% CI: 11-33) of samples, showing genotype discrepancies with cervical tests. Semen treatment could not completely eliminate the virus in positive samples but reduced the positivity to one-third. No significant differences in semen and embryological variables, clinical pregnancy and live birth rates, neonatal and obstetrics outcomes were observed in subjects with positivity in semen or cervix compared to respective negative groups. Cumulative live birth rates per oocyte retrieval in couples where both partners were negative or both were positive did not differ, being 37% (95% CI: 28%-47%) and 44% (95% CI: 19-73), respectively. In conclusion, HPV testing should not be considered a prerequisite for accessing ART treatments. Robust inferences for natural fertility cannot be made using our findings, as the ART setting does not fully reflect natural conditions.

BACKGROUND: Infertility presents both medical and public health challenges, with in vitro fertilization (IVF) emerging as a prominent solution, particularly when other alternatives are exhausted. However, IVF treatment raises significant ethical questions that have been under explored in the Ghanaian context. This study aimed to explore ethical constraints and dilemmas in the provision of in vitro fertilization (IVF) treatment in Ghana. METHODS: A descriptive phenomenological qualitative design was employed. Purposive sampling techniques were used to recruit 12 participants including ART experts from three in vitro fertilization (IVF) centres, ethicists and a legal practitioner. In-depth face-to-face interviews guided by an open-ended interview guide were conducted. Thematic analysis of the interviews was performed to identify major themes. RESULTS: Providing IVF treatment in Ghana raises several ethical issues, including inequitable access due to high costs and limited availability, which favour wealthier individuals and leave marginalized populations with fewer options. There are significant ethical considerations in balancing the potential benefits of successful IVF treatment outcomes against the health risks and emotional tolls on patients. Decisions about the fate of surplus embryos present moral dilemmas, including whether to preserve, donate, or discard them. Differing personal beliefs about the moral status of the embryo further complicate the ethical landscape. Ensuring informed consent is challenging due to the complex medical, ethical, and emotional implications of IVF treatment, potentially leading to compromised consent. Additionally, there are ongoing risks of breaches in confidentiality, given the sensitive nature of reproductive health data and the importance of protecting patient privacy. CONCLUSION: This study revealed that several ethical dilemmas confront both healthcare providers and couples in the process of IVF. There is an urgent need for the development of clear and uniform regulations to govern the practice of IVF treatment in Ghana, with further attention given to mitigating financial barriers and enhancing support systems for couples considering IVF treatment.

OBJECTIVE: Infertility has emerged as a significant global public health concern, with a multitude of complex underlying causes. Epidemiological evidence indicates that immunological factors are significant contributors to the aetiology of infertility. However, previous studies on the relationship between immune inflammation and infertility have yielded inconclusive results. METHODS: Mendelian randomisation (MR) is an emerging statistical method that employs exposure-related genetic variation as an instrumental variable (IV) to infer causal relationships between immune cells and infertility by modelling the principle of random assignment in Mendelian genetics. In this study, MR was employed to assess the causal relationship between 731 immune cell signatures and infertility. The data utilized in this study were obtained from publicly available genome-wide association studies (GWAS) and validated IVs, which were employed to fulfil the essential assumptions of MR analysis. RESULTS: The Mendelian randomisation analysis revealed a total of 27 statistically significant immune cell phenotypes out of 731. The risk factor with the largest odds ratio (OR) was CD28- CD25++ CD8+ %T cell [OR, 1.21; 95% confidence interval (CI), 1.04-1.42], while the protective factor with the largest OR was activated and resting Treg AC (OR, 0.89; 95% CI, 0.82-0.97). CONCLUSION: The present study has demonstrated a correlation between certain characteristics of immune cells and female infertility. These results provide clues for further research into the immune mechanisms of infertility and may inform the development of novel therapeutic strategies.

Background: Infertility is a global health challenge impacting quality of life, particularly in low and middle-income countries such as Sudan. The Fertility Quality of Life (FertiQoL) tool, a standardized questionnaire, is pivotal in assessing fertility-related quality of life. However, existing research on its utility has primarily been conducted in Global North and High-Income Countries, highlighting the need to shift away from neocolonialism to promote truly inclusive research and effective healthcare practices. Science diplomacy, through the adaptation and culturally sensitive implementation of research tools, can serve as a catalyst for addressing health disparities on a global scale. This study aims to assess methodological and cultural considerations that impact the implementation of the FertiQoL tool in Sudan, framed within the context of science diplomacy and neocolonialism. By investigating the challenges and opportunities of utilizing this tool in a non-Western cultural setting, we seek to contribute to the broader discussion on decolonizing global health research. Methods: Utilizing an explanatory sequential design involving surveys and interviews, we conducted a study in a Sudanese fertility clinic from November 2017 to May 2018. A total of 102 participants were recruited using convenience sampling, providing socio-demographic, medical, and reproductive history data. The Arabic version of FertiQoL was administered, with 20 participants interviewed and 82 surveyed (40 self-administered and 42 provider-administered). We applied descriptive statistics, one-way ANOVA, thematic analysis, and triangulation to explore methodological and cultural nuances. Results: Most participants were educated women who lived in urban areas. While the ANOVA results revealed no statistically significant differences in FertiQoL scores based on the mode of administration [core score (F(2,99) = 1.58, p = 0.21, η 2 = 0.03) and domain scores: emotional (F(2,99) = 1.85, p = 0.16, η 2 = 0.04); mind/body (F(2,99) = 1.95, p = 0.15, η 2 = 0.04); relational (F(2,99) = 0.18, p = 0.83, η 2 = 0.04); and social (F(2,99) = 1.67, p = 0.19, η 2 = 0.03)], qualitative insights unveiled vital cultural considerations. Interpretation challenges related to concepts like hope and jealousy emerged during interviews. Notably, the social domain of FertiQoL was found to inadequately capture the social pressures experienced by infertile individuals in Sudan, underscoring the importance of region-specific research. Despite these challenges, participants perceived FertiQoL as a comprehensive and valuable tool with broader utility beyond assessing fertility-related quality of life. Conclusion: Our findings emphasize the significance of incorporating cultural sensitivity into the interpretation of FertiQoL scores when implementing it globally. This approach aligns with the principles of science diplomacy and challenges neocolonial structures by acknowledging the unique lived experiences of local populations. By fostering cross-cultural understanding and inclusivity in research, we can enhance the implementation of FertiQoL and pave the way for novel interventions, increased funding, and policy developments in the Global South, ultimately promoting equitable global health.

Background: Infertility is a fertility disorder caused by various factors, with lipid metabolism playing a crucial role in its development. The cardiometabolic index (CMI), which combines blood lipids (TG/HDL-C) and obesity-related parameters (WHtR), is a new quantitative indicator. This study used NHANES data to investigate the relationship between CMI and the incidence of infertility. Methods: We utilized data from women who took part in the National Health and Nutrition Examination Survey (NHANES) from 2015 to March 2020 to calculate the CMI index. Subsequently, we used multivariate logistic regression, smooth curve fitting, and subgroup analysis to investigate the relationship between the CMI index and infertility. Results: The logistic regression model revealed a significant positive correlation between the CMI index and infertility, even after adjusting for all confounding variables (OR=3.23, 95%CI: 1.55-6.73, p=0.0017). This association remained consistent across all subgroups (p>0.05 for all interactions). Smooth curve fitting demonstrated a positive nonlinear relationship between CMI and infertility. However, the CMI index had limited diagnostic power for infertility (AUC=0.60, 95%CI: 0.56-0.65). However, the CMI-BMI index combined with BMI had good predictive performance (AUC=0.722, 95%CI: 0.676-0.767). Conclusion: The CMI index shows a positive correlation with infertility, but its diagnostic value is restricted. The combination with BMI has good diagnostic value. Further investigation is required to determine the effectiveness of the CMI index as an early indicator of infertility.

OBJECTIVES: To gain a deeper understanding of the real experiences and needs of the patients of Peutz-Jeghers syndrome (PJS) with fertility concerns. DESIGN: A qualitative study. METHODS: Phenomenological research and Semi-structured method were conducted with the patients of PJS (N = 16), and the interview data were analyzed using inductive content analysis strategies. RESULTS: 16 patients were interviewed, including 13 women and 3 men partners. We identified 5 themes, including: (i) Heritability of disease, (ii) Potential risks of reproduction; (iii) The difficulties in raising children; (iv) family and social support. (V) Need support from multiple sources. CONCLUSION: The findings of this study demonstrate that patients with Peutz-Jeghers syndrome (PJS) who are of childbearing age experience various reproductive concerns and other manifestations. Therefore, it is essential to offer individualized psychological interventions for PJS patients at different psychological stages, with the support of healthcare professionals, family, and social networks.

CRISPR homing gene drives can suppress pest populations by targeting female fertility genes, converting wild-type alleles into drive alleles in the germline of drive heterozygotes. fsRIDL (female-specific Release of Insects carrying a Dominant Lethal) is a self-limiting population suppression strategy involving continual release of transgenic males carrying female lethal alleles. Here, we propose an improved pest suppression system called "Release of Insects carrying a Dominant-sterile Drive" (RIDD), combining performance characteristics of homing drive and fsRIDL. We construct a split RIDD system in Drosophila melanogaster by creating a 3-gRNA drive disrupting the doublesex female exon. Drive alleles bias their inheritance in males, while drive alleles and resistance alleles formed by end-joining cause dominant female sterility. Weekly releases of RIDD males progressively suppressed and eventually eliminated cage populations. Modeling shows that RIDD is substantially stronger than SIT and fsRIDL. RIDD is also self-limiting, potentially allowing targeted population suppression.

Background: Depression is increasingly recognized as a factor affecting infertility and the causal relationship between them remains controversial. The aim of this study was to explore the relationship between depression and infertility using Mendelian randomization (MR) and cross-sectional study, and to explore the potential mediating role of obesity. Methods: The cross-sectional study used data from the National Health and Nutrition Examination Survey (NHANES) 2013-2018. Multivariable-adjusted logistic regression was used to assess the association between depression and infertility risk, and mediation analysis was to examine the mediating effect of obesity. Then, we performed MR analyses to investigate the causal effect of depression on infertility. Instrumental variables for depression were obtained from a genome-wide association meta-analysis (135,458 cases and 344,901 controls), and summary level data for infertility were obtained from the FinnGen database (6,481 cases and 68,969 controls). Results: In the cross-sectional study, a total of 2,915 participants between the ages of 18 and 45 were included, of whom 389 were infertile. We observed that depression was strongly associated with an increased risk of infertility (OR=1.66, 95%CI: 1.19, 2.33), and this relationship remained significant in mild (OR=1.45, 95% CI: 1.09, 1.93), moderate (OR=1.89, 95% CI: 1.26, 2.84), and severe depression (OR=1.74, 95% CI: 1.02, 2.99). Mediation analysis showed that obesity mediated 7.15% and 15.91% of the relationship between depression and infertility for body mass index and waist circumference. Furthermore, depression significantly increased the risk of infertility in both the general obesity (OR=1.81, 95%CI=1.20-2.73, P<0.01) and abdominal obesity populations (OR=1.57, 95%CI=1.08-2.27, P=0.02) populations. In addition, the MR analysis also revealed a significant positive causal relationship between genetically predicted depression and infertility (OR=1.32, 95% CI: 1.03, 1.70). Conclusion: Depression is associated with an increased risk of infertility, with obesity playing a significant mediating role. This study underscores the importance of incorporating mental health and weight management in infertility treatment strategies.

OBJECTIVE: This work aimed to investigate the potential correlation between chromosomal polymorphisms and various reproductive abnormalities. METHODS: We examined 21,916 patients affected by infertility who sought care at the Department of Reproductive Medicine, Affiliated Hospital of Shandong Second Medical University between January 2018 and December 2022. A total of 2227 individuals identified as chromosomal polymorphism carriers constituted the polymorphism group, and 2245 individuals with normal chromosome karyotypes were randomly selected to form a control group. Clinical manifestations, histories of spontaneous miscarriage, abnormal reproductive developments, fetal abnormalities, and male sperm quality anomalies were statistically compared between these two groups. RESULTS: Of the 21,916 patients analyzed, 2227 displayed chromosomal polymorphism, representing a 10.16% detection rate. Amongst the male patients, 1622 out of 10,827 exhibited polymorphisms (14.98%), whereas 605 out of 11,089 females showed polymorphisms (5.46%). Female carriers in the polymorphism group, showed statistically significant increased rates of spontaneous abortion (29.75% vs. 18.54%), fetal anomalies (1.32% vs. 0.81%), and uterine abnormalities compared with the control group (1.32% vs. 0.81%). Male carriers in the polymorphism group had higher rates of spontaneous abortion in partners (22.87% vs. 10.37%), fetal anomalies (1.97% vs. 0.25%), compromised sperm quality (41.74% vs. 7.18%), testicular underdevelopment (2.28% vs. 0.92%), and hypogonadotropic hypogonadism (0.62% vs. 0.37%) compared with the control group. CONCLUSION: Chromosomal polymorphisms may have a certain negative effect on reproductive irregularities, including spontaneous abortions, fetal anomalies, and reduced sperm quality in males. Their clinical effects deserve further investigation.

OBJECTIVE: To investigate associations between long term residential exposure to road traffic noise and particulate matter with a diameter <2.5 µm (PM2.5) and infertility in men and women. DESIGN: Nationwide prospective cohort study. SETTING: Denmark. PARTICIPANTS: 526 056 men and 377 850 women aged 30-45 years, with fewer than two children, cohabiting or married, and residing in Denmark between 2000 and 2017. MAIN OUTCOME MEASURE: Incident infertility in men and women during follow-up in the Danish National Patient Register. RESULTS: Infertility was diagnosed in 16 172 men and 22 672 women during a mean follow-up of 4.3 years and 4.2 years, respectively. Mean exposure to PM2.5 over five years was strongly associated with risk of infertility in men, with hazard ratios of 1.24 (95% confidence interval 1.18 to 1.30) among men aged 30-36.9 years and 1.24 (1.15 to 1.33) among men aged 37-45 years for each interquartile (2.9 µg/m3) higher PM2.5 after adjustment for sociodemographic variables and road traffic noise. PM2.5 was not associated with infertility in women. Road traffic noise (Lden, most exposed facade of residence) was associated with a higher risk of infertility among women aged 35-45 years, with a hazard ratio of 1.14 (1.10 to 1.18) for each interquartile (10.2 dB) higher five year mean exposure. Noise was not associated with infertility among younger women (30-34.9 years). In men, road traffic noise was associated with higher risk of infertility in the 37-45 age group (1.06, 1.02 to 1.11), but not among those aged 30-36.9 years (0.93, 0.91 to 0.96). CONCLUSIONS: PM2.5 was associated with a higher risk of an infertility diagnosis in men, whereas road traffic noise was associated with a higher risk of an infertility diagnosis in women older than 35 years, and potentially in men older than 37 years. If these results are confirmed in future studies, higher fertility could be added to the list of health benefits from regulating noise and air pollution.

Some couples report that their relationship satisfaction increases through the experience of infertility. Few studies exist which explain how this phenomenon occurs through specific variables. We hypothesized that John Gottman's constructs of friendship and intimacy as well as shared meaning could explain how couples can achieve increased relationship satisfaction. We examined a regression analysis of cross-sectional retrospective individual data for couples who are either experiencing infertility currently or have done so in the recent past. In our nonclinical sample (n = 903), mediation analyses indicated significant influencing pathways for the Gottman shared meaning system, indicating that this construct may explain how couples achieve greater emotional bonding and couple satisfaction through infertility. These findings provide couple therapists with potential areas of focus for couples navigating infertility through the lens of Gottman Method Couple Therapy, including ways to encourage deeper mutual shared meaning amidst the infertility experience.

The aim of this study is to explore knowledge, attitude and behaviour about infertility among young people, to prevent risk factors which should threaten fertility of young people.455 non-medical and medical students participated to this study, by a simple random sampling method. Knowledge state of non-medical group about infertility management was lower than medical group. Participants of non-medical group (p = 0,041) had low knowledge about definition and causes than participants of medical group. 11,5% of female and 10,9% of male of non-medical group opted for Traditional-healer as first solution if treatment fails , none of medical group suggested this option. The first advice of respondents of non-medical was polygamy, adoption and divorce (P= 0,001). Respondents of medical (p= 0,038) had proposed to try fertility treatments more than once time if treatment fails. Government should increase efforts to improve knowledge about infertility for all scholar programs.
Le but de cette étude est d'explorer les connaissances, les attitudes et les comportements concernant l'infertilité chez les jeunes, afin de prévenir les facteurs de risque qui pourraient menacer la fertilité des jeunes. 455 étudiants non-médecins et en médecine ont participé à cette étude, par une simple méthode d'échantillonnage aléatoire. L'état des connaissances du groupe non médical sur la gestion de l'infertilité était inférieur à celui du groupe médical. Les participants du groupe non médical (p = 0,041) avaient une faible connaissance de la définition et des causes par rapport aux participants du groupe médical. 11,5% des femmes et 10,9% des hommes du groupe non médical ont opté pour le guérisseur traditionnel comme première solution en cas d'échec du traitement, aucun membre du groupe médical n'a suggéré cette option. Le premier conseil des répondants non médicaux était la polygamie, l'adoption et le divorce (P= 0,001). Les répondants médicaux (p= 0,038) avaient proposé d'essayer des traitements de fertilité plus d'une fois en cas d'échec du traitement. Le gouvernement devrait redoubler d'efforts pour améliorer les connaissances sur l'infertilité pour tous les programmes universitaires.

INTRODUCTION: The 2024 Australian evidence-based guideline for unexplained infertility provides clinicians with evidence-based recommendations for the optimal diagnostic workup for infertile couples to establish the diagnosis of unexplained infertility and optimal therapeutic approach to treat couples diagnosed with unexplained infertility in the Australian health care setting. The guideline recommendations were adapted for the Australian context from the rigorous, comprehensive European Society of Human Reproduction and Embryology (ESHRE) 2023 Evidence-based guideline: unexplained infertility, using the ADAPTE process and have been approved by the Australian National Health and Medical Research Council. MAIN RECOMMENDATIONS: The guideline includes 40 evidence-based recommendations, 21 practice points and three research recommendations addressing: definition - defining infertility and frequency of intercourse, infertility and age, female and male factor infertility; diagnosis - ovulation, ovarian reserve, tubal factor, uterine factor, laparoscopy, cervical/vaginal factor, male factor, additional testing for systemic conditions; and treatment - expectant management, active treatment, mechanical-surgical procedures, alternative therapeutic approaches, quality of life. CHANGES IN ASSESSMENT AND MANAGEMENT RESULTING FROM THE GUIDELINE: This guideline refines the definition of unexplained infertility and addresses basic diagnostic procedures for infertility assessment not considered in previous guidelines on unexplained infertility. For therapeutic approaches, consideration of evidence quality, efficacy, safety and, in the Australian setting, feasibility, acceptability, cost, implementation and ultimately recommendation strength were integrated across multidisciplinary expertise and consumer perspectives in adapting recommendations to the Australian context by using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework, which had not been used in past guidelines on unexplained infertility to formulate recommendations. The Australian process also included an established data integrity check to ensure evidence could be trusted to guide practice. Practice points were added and expanded to consider the Australian setting. No evidence-based recommendations were underpinned by high quality evidence, with most having low or very low quality evidence. In this context, research recommendations were made including those for the Australian context. The full guideline and technical report are publicly available online and can be accessed at https://www.monash.edu/medicine/mchri/infertility and are supported by extensive translation resources, including the free patient ASKFertility mobile application (https://www.askfertility.org/).
