Arm-chair Quarterback statement is about to follow - Better (different?) nutrition definitely plays a role (see disclaimer) but it also lead me to wonder if the issue affecting the Californian Condors could be a factor [See 1].

As apex predators they have elevated levels of endocrine-disrupting chemicals. Since we (humans) are also pretty much an apex predator across a wide range of species it is an almost certainly we have the same sorts of problems
