- A global perspective: characteristics of infertility‐related randomized clinical trials Yu Xi Ya‐Lei Cao Li‐Yuan Tao Song‐Zhan Gao Zi‐Run Jin Jian‐Xing Cheng Hui Jiang Zhe Zhang Andrology AbstractBackgroundInfertility is a prevalent global condition, and emerging reproductive technologies may enhance its evaluation and treatment. Understanding the current features of randomized clinical trials in infertility is crucial for improving study design and ensuring the translation of results for patient benefits.ObjectivesTo investigate the primary characteristics of randomized clinical trials related to infertility and areas where require improvement.Materials and methodsWe conducted a search on the International Clinical Trials Registry platform for eligible infertility trials between 2003 and 2022. The distribution ratio of various characteristics uploaded by infertility‐related studies on the platform was analyzed and compared according to sex and registration year.ResultsOut of the total trials, 85.3% (1,906) included only women, 8.6% (192) included only men, and 6.1% (136) included couples. The majority of retrieved trials followed a parallel arm design (91.0%) and were non‐industry‐funded (92.2%), with a median planned sample size of 131 patients (interquartile range 75–270). Among these trials, 54.5% (1,217) were conducted in Asia. The most common primary purpose of infertility‐related trials was treatment (88.8%), with over half of the investigated interventions focusing on medication (57.9%).DiscussionAsia is the leading region for research, and the drug therapy is still widely used and updated. However, support care for infertile couples has also received some preference. Areas that require improvement and promotion include addressing male infertility and focusing on underserved regions like Africa. The results also highlight deficiencies in trial registration and masking methods, emphasizing the need for better regulation and facilitation of infertility trials in the post‐COVID‐19 era.ConclusionBased on the current status of infertility RCT studies, greater attention should be paid to infertile men and populations in underdeveloped regions like Africa in future studies, together with a standardized registration and implementation procedures. 10.1111/andr.13596 http://onlinelibrary.wiley.com/termsAndConditions#vor
