Andropause and Hematological Decline: 20-Year U.S. Male Cohort Study Insights
Reading Time: < 1 minute Introduction Andropause, often termed late-onset hypogonadism, represents a gradual decline in testosterone levels in aging males, affecting approximately 20-30% of American men over 60 years. This endocrine shift not only impacts musculoskeletal integrity and metabolic homeostasis but also exerts subtle yet significant effects on hematological health. Hematopoiesis, the process of blood cell formation, is testosterone-dependent, with androgens modulating erythropoietin (EPO) production, stem cell differentiation, and immune cell maturation. A landmark 20-year longitudinal study involving 1,250 community-dwelling U.S. males aged 45-85 at baseline illuminates these dynamics, revealing correlations between declining serum testosterone and perturbations in erythrocyte counts, leukocyte function, and thrombocyte...
