The 50s: A Turning Point—AI Unveils "Three Keys" Determining Male Aging and Longevity
Shigeo Horie, Director of the Asia Longevity Research Institute, and colleagues published research in Communications Medicine, revealing that a combination of testosterone, inflammation, and kidney function is a "turning point in aging" in men in their 50s, significantly increasing cancer risk. This AI-driven study offers a new diagnostic paradigm for longevity and preventive medicine.

Shigeo Horie, Director of the Asia Longevity Research Institute (Specially Appointed Professor, Juntendo University Graduate School of Medicine), along with his co-researcher, Visiting Professor Nobuo Okui, published their latest research findings in "Communications Medicine," a medical journal under Nature Portfolio. This large-scale clinical study, which analyzed data from 5,854 Japanese men over 17 years using AI (artificial intelligence), is the first to mathematically identify the branching point of aging and longevity in men, attracting international attention as it brings a new trend to the field of longevity and preventive medicine.
■ Research Overview: The "Negative Chain" of Three Indicators and the Turning Point in the 50s
This research revealed that the combination of three indicators—"testosterone (male hormone)," "inflammation (CRP)," and "kidney function (creatinine)"—fundamentally influences the quality of aging.
While traditional health screenings have individually evaluated each value, AI analysis has for the first time shown that when these three indicators simultaneously trend negatively, the aging of the entire bodily system accelerates, and cancer risk significantly increases. Even if each value is within the "normal range," this combination raises the risk—this was a blind spot not visible with single indicators.
Decreased testosterone + chronic microinflammation + decreased kidney function → "Negative chain of aging" begins, and cancer risk significantly increases.
Furthermore, mathematical analysis (piecewise regression) for the first time in the world calculated that a "decisive turning point" for this negative chain exists in the early 50s. External validation using large-scale data from the U.S. National Health and Nutrition Examination Survey (NHANES) also confirmed that the incidence of prostate, lung, and bladder cancers was significantly higher in the high-risk group compared to the normal group, demonstrating the universal applicability of this finding across race and nationality.
■ Significance for the Industry: Re-evaluating Aging as a "Controllable System"
The significance of this research for the fields of medicine and longevity science goes beyond merely discovering new indicators. Until now, hormone levels, inflammation levels, and kidney function values have been discussed in independent contexts. This research re-evaluates them integrally as part of a "biological system" and presents a completely new diagnostic paradigm for multidimensional assessment of aging.
The perspective of visualizing risks before the onset of disease and enabling preventive intervention can be a key to achieving both medical cost containment and improved Quality of Life (QOL) in a globally accelerating aging society. Its publication in a prestigious academic journal like Nature Portfolio indicates that this evaluation is shared by the international research community.
■ Researchers' Comments
Upon the publication of the paper, Shigeo Horie and Nobuo Okui offered the following comments (from the original paper):
"This research inherits the spirit of men's health, passionately championed by the late Professor Etsumei Kumamoto, and visualizes its theories through the latest AI technology. What we discovered over 17 years is not just a harbinger of disease, but a 'blueprint for longevity' on how to age healthily. We are confident that these findings will contribute to the healthy longevity of many men."

■ Related Research Initiatives at Asia Longevity Research Institute
Following the announcement by Director Shigeo Horie, the Asia Longevity Research Institute is also advancing its unique exploratory research applying the biological system evaluation framework demonstrated in this study. Efforts have just begun to verify longevity biomarkers based on the genetic and lifestyle backgrounds unique to Asians, and to design comprehensive preventive intervention programs, with future progress to be announced sequentially.
■ Future Outlook
Under the philosophy of "transforming aging from an irreversible phenomenon to a controllable system," the Asia Longevity Research Institute will continue to work at the forefront of longevity science as an institution that consistently promotes everything from basic research to social implementation. Building on the insights pioneered by Director Shigeo Horie, we hereby declare our commitment to continuously disseminate research results that contribute to healthy longevity across Asia.
