Testosterone deficiency in the ageing male
Abstract
Over the past years, a growing demand for testosterone replacement therapy in aging men has been noted in the US as well as in Europe. The current evidence for detrimental consequences of low testosterone in old men is largely based on retrospective studies. On the other hand, prospective placebo-controlled randomized trials investigating clinically relevant endpoints are limited. Clinical benefits of testosterone replacement therapy in ageing men include improved sexual function and libido, increase in muscle mass and -function, as well as bone mass accrual. Whether testosterone supplementation in ageing men confers an altered risk for cardiovascular disease and/or prostate cancer remains unclear. Ongoing clinical trials (e. g. TRAVERSE trial, NCT03 518 034) will help to resolve these questions.
Der Testosteronmangel des alternden Mannes ist nach wie vor nicht präzise definiert. Verschiedene Fachgesellschaften fordern zwar unisono das Vorliegen spezifischer klinischer Symptome in Verbindung mit konsistent erniedrigten morgendlichen Testosteronspiegeln. Allerdings existieren für letztere keine einheitlichen Grenzwerte. Erschwerend kommt hinzu, dass einzelne Symptome des Testosteronmangels bei unterschiedlichen Testosteron-Schwellenwerten auftreten können. TESTOSTERONERSATZTHERAPIE – ANTI-AGING ODER FALSCHE HOFFNUNG?: Während zahlreiche retrospektive und kleinere prospektive Studien mit suboptimalem Design den Nutzen einer Testosteronersatztherapie im Alter nahelegen,…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
