Testosterone is the new canine tooth.
- adam_arthur 4y agoMentioned in a top level comment, but higher bodyfat levels have been proven to correlate with lower testosterone levels. May explain a large portion of this shift. I wonder if they normalized for bodyweight in this study
- nitrixion 4y agoI'd be interested in reading more about this. I'm curious if that correlation is due to people with lower bodyfat being more likely to exercise regularly which, in turn, would increase testosterone levels. Seems like the obvious conclusion, but that doesn't mean it is correct.
- shanewwarren 4y agoThis is mostly a joke, but for a few friends that have had trouble, I've recommended getting into squats and deadlifts (weightlifting more generally).
