That sounds fairly urban legendy, though it can depend on the user and their anatomy, of course.

I know many people who've used or worked with these devices for years and that has not been the case for them.

That said, due to the types of cage mechanics, weight and makeup of different cage materials, etc, there is definitely the possibility of some physical issues, including some nerve issues. It usually just things like skin irritations and discomfort though.

These days, there are a LOT of knockoffs of the major brands (like the Holy Trainer series) that are made with seriously questionable materials that don't have temperature tolerance/reforming, are missing edge filleting, etc. So if you do decide to engage in this sort of play, do your homework, read reviews, talk to communities, and don't order some random cheap thing off AliExpress.

The penis also lacks muscles (which do atrophy with lack of use). The more reputable reports from long-term wearers suggest that the plumbing still works even with near constant wear, provided that care is taken to ejaculate once in a while (e.g., monthly).

Because the purpose of male chastity devices is to prevent erections and orgasms, long-term wearers (who are a minority compared to the amount of folk who use such as device as a form of (prolonged) foreplay or as part of an erotic roleplaying scenario) may achieve such an ejaculation by means of a prostate massage (i.e., 'milking' him). The health goal here is mainly to keep the prostate healthy though.

Chafing, pinching, skin irritations; those are common health related issues though.

Or do, just to explore the different models cheaply, but treat them as novelty items. And yes, do read up on reviews, or ask in online communities. This is, quite emphatically, not a one-size-fits-all item.
