In men, 95% of circulating testosterone is derived from testicular production
Testosterone reaches peak levels in men at approximately age 30, after which levels steadily decline at a rate of 1% to 2% annually. In the human body, most testosterone is bound to a carrier molecule, while only a small fraction (1-3%) exists as free. . Free testosterone is considered to represent the most potent form of T in terms of activity.
Endogenous serum testosterone levels fluctuate according to a circadian pattern, as well as in response to stress. Testosterone levels drop abruptly with acute illnesses, such as myocardial infarction, sepsis, or trauma, and low testosterone levels are associated with several chronic conditions, such as diabetes, kidney failure, malignancies, hypertension, and dyslipidemia.
Testosterone is a hormone that plays a key role in the metabolism of carbohydrates, fats and proteins. Testosterone deficiency is associated with increased fat mass (particularly central adiposity), reduced insulin sensitivity, glucose intolerance, elevated triglyceride and cholesterol levels, and low HDL cholesterol levels. All of these factors are found in metabolic syndrome (MetS) and type 2 diabetes, contributing to cardiovascular risk. Lower serum testosterone levels and a greater burden of chronic disease. Calculated bioavailable testosterone had a significant positive association with processing speed, sustained attention, and working memory in men over 60 years of age.
A meta-analysis of individual participant data evaluated the impact of testosterone on individual quality of life tools. Testosterone improved all domains of the AMS scale, which is highly sensitive to sexual discomfort in men. Testosterone treatment significantly improved the SF-36 or SF-12 domains of social functioning, role limitations due to emotional problems, and mental health composite score. In subgroup analysis, differences between AMS score during testosterone treatment, smoking, and diabetes, which are known to reduce quality of life, could have mitigated improvements in quality of life during testosterone treatment.
Two recent large randomized trials of tetosterone (T) and meta-analyses of randomized trials showed no signal of adverse cardiovascular (CV) events, and treatment with T in a lifestyle intervention setting reduced type 2 diabetes by 40%. % in men at high risk. Exercise training interventions improve blood pressure and endothelial function in middle-aged and older men, without comparable benefits or additive effects of T treatment. Therefore, exercise training improves cardiometabolic health in middle-aged and older men. greater when applied effectively as a supervised regimen incorporating aerobic and resistance modalities.
