News | Testosterone Is About More Than Sex: Its Far-Reaching Effects on Men’s Overall Health
Testosterone has long been considered the key hormone in male reproductive development and the formation of secondary sex characteristics. Recent research shows that its role extends far beyond sexual function, affecting cardiovascular and metabolic function, bone health, and mental well-being. As men’s health concerns grow worldwide, comprehensive testosterone research and personalized treatment strategies are increasingly important.
A major review by researchers from Germany, Qatar, Jordan, and Hungary was published in UroPrecision on February 18, 2025 (DOI: 10.1002/uro2.115). Drawing on clinical evidence, it systematically examined testosterone’s effects on cardiovascular health, metabolism, fertility, and mental health in men. It also outlined a future treatment approach centered on precision medicine and artificial intelligence (AI) to provide safer, more individualized care.
Testosterone production and regulation depend on the hypothalamic-pituitary-gonadal axis (HPG axis), with broad effects on libido, muscle growth, fat distribution, bone density, and mood. Imbalance may cause testosterone deficiency (hypogonadism) or excess testosterone. Deficiency commonly presents with erectile dysfunction, osteoporosis, or depression, while excess may cause mood changes, hirsutism, and even male infertility.
Although **testosterone replacement therapy (TRT)** has long been used for testosterone deficiency, its cardiovascular safety, effects on prostate health, and long-term outcomes remain controversial. Traditional treatments include injections, gels, and implants, while oral clomiphene and gonadotropin therapies have also been explored in recent years. Individual variation makes more precise treatment adjustment essential.
Advances in biomarkers offer new opportunities for testosterone management. In addition to free testosterone and sex hormone-binding globulin (SHBG), researchers are using technologies such as liquid chromatography–tandem mass spectrometry (LC-MS/MS) and examining newer markers such as insulin-like factor 3 (INSL3). Progress in genomics and proteomics may also help identify individual differences in testosterone metabolism and receptor sensitivity.
AI is seen as an intelligent engine for testosterone treatment. It can combine clinical and genetic data to help physicians personalize TRT dosing and predict response and adverse effects, maximizing benefit while minimizing risk.
“Testosterone is not merely a reproductive hormone; it is a ‘life hormone,’” said first author and urologist Dr. Aksam Yassin. “With precision medicine and advanced diagnostic tools, we are moving from one-size-fits-all treatment toward a new era of individualized, data-driven care.”
The review stresses that future men’s health management should not simply focus on supplementing testosterone, but on optimizing its role across conditions including osteoporosis, heart disease, metabolic syndrome, and even Alzheimer’s disease. Testosterone is also being studied as a potential male contraceptive. This life-course approach, spanning prevention, treatment, and quality of life, could substantially improve men’s health worldwide.
The study was supported by the Chinese Academy of Sciences and may have broad clinical implications for the treatment and health outlook of millions of men.
