Relationship between testosterone deficiency and cardiovascular risk and mortality in adult men

Area of Science:

• Endocrinology
• Cardiology
• Metabolic Health

Background:

• Classic male hypogonadism presents with decreased libido, erectile dysfunction, and osteoporosis.
• Reduced serum testosterone (T) levels, due to aging, chronic disease, or androgen deprivation therapy (ADT), mimic hypogonadism symptoms.
• Low T is increasingly recognized as a potential cardiometabolic risk factor.

Purpose of the Study:

• To review literature on the cardiovascular role of testosterone (T).
• To discuss the association between low T levels and adverse metabolic profiles (insulin resistance, metabolic syndrome, diabetes).
• To investigate mechanisms linking hypogonadism to cardio-metabolic risk and explore T's role in male mortality.

Main Methods:

• Literature review of observational studies and clinical trials.
• Medline search for studies on T levels, cardiovascular disease, and mortality.
• Synthesis, tabulation, and interpretation of research findings.

Main Results:

• Low T is associated with increased fat mass, decreased lean body mass, and reduced muscle strength.
• Evidence suggests a link between low T and adverse metabolic profiles, including insulin resistance and metabolic syndrome.
• The review explores potential mechanisms and the complex relationship between T levels and male mortality.

Conclusions:

• Low serum testosterone is a significant factor in male health, impacting metabolic and cardiovascular outcomes.
• Understanding the mechanisms behind low T's effects is crucial for managing cardio-metabolic risk.
• Further research is needed to clarify the protective or detrimental role of T in mortality.
