Cardiovascular Safety of Testosterone Replacement Therapy in Hypogonadal Men
Bibliographic record
Abstract
Testosterone replacement therapy (TRT) aims to restore serum testosterone levels in men with hypogonadism. Symptoms associated with hypogonadism include reduced libido, erectile dysfunction, fatigue, depression, and loss of muscle mass and bone density. The primary purpose of TRT is to alleviate these symptoms and improve quality of life by restoring serum testosterone levels to the physiological range. The prevalence of hypogonadism in men increases with age, affecting approximately 2–5% of middle-aged and older men and up to 20% of elderly men. Despite its therapeutic benefits, the cardiovascular safety of TRT remains a topic of debate and investigation. Cardiovascular disease is a leading cause of morbidity and mortality among men, and any therapy that might influence cardiovascular risk requires careful evaluation. Early observational studies raised concerns about potential adverse cardiovascular outcomes associated with TRT. These findings prompted regulatory agencies to issue warnings and recommend further research. In response, more recent trials, including the TRAVERSE Study, have provided new insights into the relationship between TRT and cardiovascular health. This article aims to provide a review of recent evidence on the cardiovascular safety of TRT.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
