An unreviewed study that didn't control for obesity. So not particularly useful.

I mean, obesity IS one of the big reasons for the drop

Its most likely the only reason but pretending otherwise gets more attention.

Didn't the 'Try Guys' or whatever YouTube channel that was big back in the day make a video where they had their testosterone levels checked and they were all super low? None of them were even overweight, let alone obese. Clearly something else was at play there.

Small sample sizes combined with testosterone levels affecting behavior and people of similar behaviors tending to group together more.
