Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — testosterone and focus

The relationship between testosterone therapy and cardiovascular risk in men is one of the most debated topics in men's health. Headlines have warned of increased heart attack risk, yet the research tells a more nuanced story. Age, pre-existing cardiovascular disease, oestrogen levels, dosage, and delivery method all appear to play significant roles. This article examines the key findings from a major insurance-data study, explores the clinical questions it raises, and explains what men and their doctors should consider before starting or continuing testosterone therapy.

Dr. Kate Placzek explores the neuroendocrine science behind this finding — and what it reveals about testosterone’s role in dopamine, reward and social behaviour.
