Background: Testosterone deficiency is associated with heart failure (HF) progression and poor prognosis. Testosterone therapy has been shown to improve exercise capacity in patients with chronic HF, but no trial has evaluated the impact of replacement in patients with demonstrated testosterone deficiency. Methods: Prospective, randomized, double-blind, placebo-controlled, and parallel-group trial comparing testosterone replacement with placebo in males with chronic HF with reduced ejection fraction (HFrEF) and testosterone deficiency (NCT01813201). Long-acting undecanoate testosterone at a fixed dose of 1000 mg was supplied by intramuscular injection at inclusion and then every 3 months. The placebo group received isotonic saline serum. Patients were randomly allocated 1:1 to testosterone or placebo while receiving optimal medical therapy, and the study was conducted for 12 months. Results: The final sample comprised 29 patients, 15 in the placebo group and 14 in the testosterone group (aged 65 ± 8, 62% with an ischemic etiology, left ventricular ejection fraction [LVEF] 30% ± 6%, 69% New York Heart Association functional [NYHA II]). After 12 months, testosterone replacement increased testosterone levels (P =.002) but was not associated with benefit in terms of clinical symptoms and functional capacity including NYHA class, Framingham score, Minnesota Living Heart Failure Questionnaire, 6-minute walk test, or LVEF and N-terminal pro-B-type natriuretic peptide levels. No significant side effects associated with testosterone treatment were observed. No effects were found in other hormonal, metabolic, and bone turnover biomarkers. Conclusion: In patients with HFrEF and testosterone deficiency, replacement therapy was not associated with any significant improvement.
