    Background: Complex issues, including a failure to consider the perspectives of people with fertility problems when selecting outcomes, variations in outcome definitions, and outcome reporting bias, make the results of infertility research difficult to interpret. Objectives: To develop a core outcome set to standardise outcome selection, collection, and reporting across future randomized controlled trials and systematic reviews evaluating potential treatments for infertility. Methods: Healthcare professionals, researchers, and people with fertility problems were brought together in an open and transparent process using formal consensus science methods including a three-round Delphi survey (372 participants from 41 countries) and consensus development workshop (30 participants from 27 countries) (1). Results: The core outcome set consists of: (1) viable intrauterine pregnancy confirmed by ultrasound (accounting for singleton, twin, and higher multiple pregnancies); (2) pregnancy loss (accounting for ectopic pregnancy, miscarriage, stillbirth, and termination of pregnancy); (3) live birth; (4) gestational age at delivery; (5) birth weight; (6) neonatal mortality; and (7) major congenital anomaly. Time to pregnancy leading to live birth should be reported when applicable. Conclusions: Embedding the core outcome set within randomized controlled trials and systematic reviews should ensure the comprehensive selection, collection, and reporting of core outcomes. Research funding bodies, the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) statement, and over 80 specialty journals, including Cochrane Gynaecology and Fertility Group, Fertility and Sterility, and Human Reproduction, have committed to implementing this core outcome set

    Study Question Can consensus definitions for the core outcome set for infertility be identified in order to recommend a standardized approach to reporting? Summary Answer Consensus definitions for individual core outcomes, contextual statements, and a standardized reporting table have been developed. What is Known Already Different definitions exist for individual core outcomes for infertility. This variation increases the opportunities for researchers to engage with selective outcome reporting, which undermines secondary research and compromises clinical practice guideline development. Study Design, Size, Duration Potential definitions were identified by a systematic review of definition development initiatives and clinical practice guidelines and by reviewing Cochrane Gynaecology and Fertility Group guidelines. These definitions were discussed in a face-to-face consensus development meeting, which agreed consensus definitions. A standardized approach to reporting was also developed as part of the process. Participants/Materials, Setting, Methods Healthcare professionals, researchers, and people with fertility problems were brought together in an open and transparent process using formal consensus development methods. Main Results and the Role of Chance Forty-four potential definitions were inventoried across four definition development initiatives, including the Harbin Consensus Conference Workshop Group and International Committee for Monitoring Assisted Reproductive Technologies, 12 clinical practice guidelines, and Cochrane Gynaecology and Fertility Group guidelines. Twenty-seven participants, from 11 countries, contributed to the consensus development meeting. Consensus definitions were successfully developed for all core outcomes. Specific recommendations were made to improve reporting. Limitations, Reasons for Caution We used consensus development methods, which have inherent limitations. There was limited representation from low- and middle-income countries. Wider Implications of the Findings A minimum data set should assist researchers in populating protocols, case report forms, and other data collection tools. The generic reporting table should provide clear guidance to researchers and improve the reporting of their results within journal publications and conference presentations.
