Myths vs facts: STI Test and longevity

The question about myths vs facts regarding STI testing and longevity is not directly addressed in the provided context. The available information covers individual genetic variants (e.g., PPARGC1A, FTO, BDNF) and their weak associations with metabolic or fitness traits—not sexually transmitted infections. STI testing is a valuable preventive tool, as untreated infections like HIV, syphilis, or HPV can lead to severe long-term health issues that reduce life expectancy. However, a direct causal effect of STI testing on longevity is not supported by randomized trials; the benefit is indirect through early detection and treatment. Many online claims exaggerate either the risks of STIs or the protective effect of testing. The reality is that regular STI testing is advisable for sexually active individuals with multiple partners, but it is no guarantee of a longer life. The evidence level is rated as 'unclear' because the context provides no relevant data.
