Evidence check: STI Test in the context of Langlebigkeit

An STI test (sexually transmitted infection) is primarily a tool for sexual health, not longevity. However, untreated STIs such as HIV, syphilis, or HPV can have long-term health consequences that affect life expectancy – e.g., increased cancer risk (HPV), cardiovascular damage (syphilis), or immune deficiency (HIV). The evidence for a direct benefit of STI testing on longevity is indirect and population-dependent. For risk groups (e.g., multiple partners, unprotected sex), regular testing is sensible, but as a universal longevity screening it is not supported. The predictive value of a single STI test is limited by window periods. From an evidence-based perspective, STI testing is an important preventive measure but not a specific longevity biomarker. Beware of marketing that sells STI tests as 'anti-aging' checks.
