Abstract
Sex steroids exert diverse, divergent and dynamic effects on muscle and bone. Beyond their essential role in sexual dimorphism, sex steroids contribute to the accrual, maintenance and age-related involution of the musculoskeletal system. Falls and fractures occur, dire consequences of musculoskeletal attrition and functional decline, in association with a critical reduction in sex steroids in older individuals. Conversely, the reversal of sex steroid deficiency and therapies that specifically target sex steroid receptor signalling (e.g. SARMs) mitigate aspects of musculoskeletal aging. This chapter will discuss key principles in sex steroid biology, evidence from preclinical and clinical studies on their anabolic and anti-catabolic effects on muscle and bone, and therapeutic possibilities for osteosarcopenia.
