Early identification of modifiable factors associated with decreased testosterone levels may contribute to improved prevention of androgen deficiency and related health conditions.\n\nThis population-based analytical cross-sectional observational study aims to investigate anthropometric, functional and lifestyle-related factors associated with decreased total testosterone levels in middle-aged men. Approximately 600 men aged 35-59 years residing in the Andijan region of Uzbekistan will be recruited.\n\nParticipants will undergo comprehensive assessment including anthropometric measurements, functional performance tests, standardized questionnaires and laboratory determination of serum total testosterone levels. Anthropometric variables will include body mass index, waist circumference, hip circumference, waist-to-hip ratio and waist-to-height ratio. Functional status will be assessed using hand-grip strength, five-times chair-stand test, 4-meter walk test, balance assessment and the six-minute walk test. Lifestyle-related factors including physical activity, sleep quality, dietary habits, smoking, alcohol consumption and psychoemotional status will be evaluated using validated questionnaires.\n\nThe study aims to identify determinants of decreased testosterone levels and develop a predictive model for early identification of androgen deficiency in middle-aged men.",[27,28,29,30],"Testosterone
