A recent study conducted by researchers at the University of Western Australia has revealed a concerning finding – men with low testosterone levels are at a higher risk of premature death. Testosterone, the primary male sex hormone, plays a crucial role in the development of reproductive organs, muscle and bone mass, hair growth, and other secondary male sexual characteristics.
The research, which analyzed data from 11 high-quality studies involving over 24,000 participants tracked for at least five years, found a significant association between testosterone levels and lifespan. Typically, men experience a decline in testosterone levels as they age, with levels ranging from 300-1000ng/dL in their 20s and 30s, 200-700ng/dL in their 40s and 50s, and 100-600ng/dL in their 60s and beyond.
The study identified that men with baseline blood testosterone levels below 213 ng/dL faced a heightened risk of mortality, with heart disease being the leading cause of death among individuals with low testosterone levels. Daniel Kelly, a senior lecturer in biochemistry at Sheffield Hallam University, highlighted the connection between heart disease and erectile dysfunction, noting that the processes underlying heart disease may also contribute to erectile issues.
While erectile dysfunction often precedes symptoms of heart disease, it can serve as an early warning sign of potential cardiovascular problems. Testosterone’s significant impact on erectile function underscores the link between testosterone levels and heart health. It’s worth noting that declining testosterone levels can be attributed to factors beyond aging, including chronic illnesses.
Although the study did not delve into the specific causes of reduced testosterone levels, the implications are clear – low testosterone levels are associated with an increased risk of death. Understanding the interplay between testosterone levels, chronic diseases, and mortality could provide valuable insights into improving men’s health and longevity.
