Sažetak | This paper aims to find out the utility of testosterone replacement therapy (TRT) in managing LOH, focusing on its implications for muscle mass, strength, bone density, sexual function, mood, cognitive abilities, cardiovascular health, and prostate well-being. Gonads, including testes in males, are essential for producing reproductive cells and hormones like T, which is crucial for male physical characteristics, sexual function, and overall health. T production is regulated by the HPG axis and affects various bodily functions, from muscle and bone health to mood and cognitive abilities. Hypogonadism, characterized by reduced T production, can arise from issues within the testes themselves (primary) or from problems in the hypothalamus or pituitary gland (secondary). Diagnosing this condition involves measuring serum T levels. Testosterone replacement therapy is explored as a treatment for LOH in older men, offering potential benefits for muscle mass, strength, bone density, sexual function, and mood. But TRT's impact on cardiovascular and prostate health remains controversial. Various TRT delivery methods exist, including injections, patches, gels, oral applications, and nasal gels, each with specific advantages, potential side effects, and monitoring requirements to manage risks effectively. Despite advances, no TRT method fully meets all criteria for optimal treatment as defined by the WHO, with ongoing research and individualized patient considerations guiding therapy choices. |
