Background: Recent research has demonstrated earlier testicular and pubertal development in Western boys. New ultrasound-based references of testicular growth in Norwegian boys are now available. Population specific references for FSH, LH and sex steroid hormones have not been previously available in Norwegian children and adolescents.Objective and hypotheses: We aimed to provide an elaborate description of pubertal development in a sample of contemporar...

Introduction: Male puberty is initiated by endocrine signaling in the hypothalamic-pituitary axis whereby follicle-stimulating hormone (FSH) and luteinizing hormone (LH) enable testicular maturation and synthesis of testosterone. Recent publications have eluded to overnutrition and obesity as relevant factors that may accelerate the timing of puberty. Attainment of testicular volume (TV) 4 ml measured by Prader orchidometer remains the definition of male puber...
