Women ofte report heart problems as nausea, differently than men, who report it as pain.
So this side effect may be under-reported or misdiagnosed in women, so not male-only.

Note that I'm not saying that it is more prevalent. So far as I know, there is no data to support my suspicion. And, personally, I suspect that if some of that is heart trouble, it's the minority of cases of Covid (and Covid vaccine) fatigue. But I note that the possibility exists that this could be prevalent.
