Testosterone is a hormone that plays a key role in carbohydrate, fat and protein metabolism in men. Age-related decrease in testosterone levels, which is facilitated by the development and progression of comorbidities, especially type 2 diabetes mellitus, obesity, dyslipidemia, can have a significant impact on the development of cardiovascular diseases in men and increase the risk of premature death. The paper presents an analysis of modern literature data on the prevalence of late-onset hypogonadism and its impact on the development of cardiovascular pathology in men. An analysis of researches presented in the search database and MedLine database was performed using the keywords “testosterone”, “male”, “late-onset hypogonadism”, and “cardiovascular diseases”. The controversy of a number of hypotheses about the role of androgen deficiency in the development of cardiovascular pathology in men is shown. However, it was determined that most studies showed the correlation between androgen deficiency and the development of metabolic disorders, which are factors for the development of metabolic syndrome, obesity, type 2 diabetes mellitus. In turn, these comorbidities are direct factors that lead to the early onset and progression of vascular pathology and associated mortality in older men. Testosterone therapy is necessary in men with type 2 diabetes mellitus and clinically and laboratory confirmed testosterone deficiency, provided that its safety standards are met. Due to ambiguous results regarding the effect of testosterone on the development of cardiovascular disease, this issue needs further study.
