How are Progesteron and longevity related?

The relationship between progesterone and longevity remains scientifically inconclusive. Progesterone is a key steroid hormone involved in female reproduction, but also exerts effects on the brain, bones, and immune system. Preclinical studies suggest neuroprotective and anti-inflammatory properties that could theoretically slow aging processes. However, robust human trials directly linking progesterone to extended lifespan are lacking. Progesterone is commonly used in hormone replacement therapy (HRT) during menopause, where benefits must be weighed against risks (e.g., breast cancer). The evidence is best described as mechanistic: plausible biological pathways exist, but no strong human longevity data from RCTs. Self-administering progesterone for anti-aging purposes is not advised and should only be considered under medical supervision.
