The effectiveness of fin and dut isn't due to prostate shrinking (which may be a result of the drugs' mechanism but not the cause of stopping MPB) or deactivation (the same amount of 5-ar and T are still produced by the body) but because they bind to the 5-ar type II enzyme, rendering it unable to bond with testosterone. The idea of not ejaculating to stop MPB has floated around/been experimented with for decades but unfortunately doesn't work, at least not in a way that comes anywhere near halting hair loss. (But then if it did, it would still make having hair pretty pointless anyway, if you know what I mean
)
Right now these 2 drugs are the only available MPB treatments that safely work for most men, but there are 2 adjunct treatments that might buy a little time on their own: minox and keto.
Edit: I suppose the bottom line is that no one needs to take fin/dut for MPB in the literal sense, but for those of us who want to keep our hair, they're what we are stuck with for now
