My psych degree is nearly a decade in the past for me, but numerous disorders have symptoms that include avoidance of treatment or lack of follow-up. For instance, schizophrenics and manic depressives are notorious for going off their meds. That's not to say there aren't reasons for that or that everyone with those conditions does so, but it's a widely acknowledged observation that any psychologist with proper training makes sure to incorporate into their interactions with patients (doubly so with meds, since in the vast majority of states that further involves a psychiatrist).
Of course, those are meds, which aren't part of every treatment and would be highly unlikely in treatment regimens for what we're discussing in here (barring comorbid conditions that would necessitate their use).
Sawneeks is pretty spot-on with this and likely further findings being more about trying to shift the cultural conversation, thereby perhaps opening the door for men to seek treatment or, probably more likely, for guardians and officials such as parents and teachers being more likely to broach the topic and be on the lookout regarding the boys they raise/teach. Honestly, the likelihood of these moves affecting fully-grown adult men is a crapshoot; much more important for these findings to influence how we approach children, adolescents, and those not yet born.
