Fertility as a proxy?

Fertility is indeed discussed as a proxy for vitality and longevity by Andrew Huberman. He highlights that optimizing fertility, even for those not wishing to conceive, can serve as a powerful indicator and enhancer of overall vitality and longevity. The rationale is that the mechanisms supporting reproductive health also support general physical and mental health.

For instance, interventions like managing sleep, reducing stress, and nutrition not only enhance reproductive functions but also improve overall vitality. These factors are integral in maintaining healthy biological systems, essential for both fertility and long-term health 1 2.
