The Korean Society of Men's Health and Aging (KSMHA) acknowledges the necessity for an updated statement on testosterone therapy driven by evolving clinical practices and new research findings. The primary purpose of this position statement is to provide a tailored, evidence-based framework that aligns with international best practices while addressing the unique needs of the Korean population. Additionally, this statement addresses the growing recognition of both organic and functional hypogonadism, particularly given the rising rates of obesity and metabolic syndrome, which affect testosterone levels and overall health. The position statement addresses key areas, including the clinical and laboratory diagnosis of male hypogonadism, with a focus on appropriate cut-off values for testosterone levels in Korean men, and provides guidance on assessing treatment outcomes. In this statement, we present an objective position on testosterone therapy based on recent studies that have carefully evaluated its effectiveness and safety. By providing a tailored framework for the management of male hypogonadism, KSMHA aims to enhance patient care and align Korean practices with global standards.
