Significant sex differences in Covid-19 immune response

Would amusingly fit in with many of the "why aren't crowds getting this?" It is largely crowded places with large communal restrooms that have associated outbreaks.
That said, I'm calling this my pet idea, in large because I think it is a silly one. Do I think it is in the realm of plausible? I mean, yeah. But I don't think it has stepped into the realm of likely.
They controlled for BMI in cohort A, and performed an adjusted analysis in cohort B, so I'm somewhat satisfied on that front.
It's funny - when you watch the little league world series, the kids spit too.

And then extremely anecdotally: the only people I personally know who have gotten sick† in my ~25–35-year-old social circle have been guys who are, as they say, “on the bike”. Geared up, if you know what I mean.
†and they’ve all recovered well; they had about a week of pretty nasty flu-like symptoms, but then bounced back with bed rest
Steroid risks are maybe a bit murkier than the risks of jumping off of things, so it's possible there are more people with inaccurate perceptions of the risks, which might explain your perception of that group.
Because you can’t plausibly do a long-term blinded trial where you take a healthy population and dope them up. The in vitro data is enough to make any institutional review board blanch.
So you have to rely on self-reported usage. Which is incredibly unreliable, and full of confounds. (My bias, my fairly well-informed bias, is that nobody is just doing steroids. There is always another drug or high-risk activity.)
So yeah. Steroids are dangerous. Do we know exactly how bad, especially in comparison to other drugs of abuse? Not as far as I can tell. But bad enough that you should absolutely be wary of steroids. (Also there’s gradations of dangerous. You stay away from trenbolone.)
I don't know that many people in the steroid-abusing demographics (it was less of a thing in my age demographic than it is with the youth of today), but I am aware that it's dangerous.
Especially since at least one of them was at this early super-spreader event:

But also how dare you suggest that the highest levels of competitive sport, where the margin of victory is razor-slim, and you only have a few years of peak performance, are infested with drugs? How crass. How immoral. I miss the simpler days of my youth, when Hulk Hogan told us we just had to take our vitamins.
"Steroids are often used in patterns called "cycling." This involves taking multiple doses of steroids over a specific period of time, stopping for a period, and starting again."

I actually think followup studies on gender minorities could be really interesting here - do people taking testosterone get sick like AMAB people who aren't taking hormones? Do AMAB people taking estrogen have better outcomes?

The transphobic people who inevitably show up in threads like this don't seem to recognize the difference, though.
Transsexuals care strictly about sex.
With that out of the way, let us continue ...
The transgender community is not usually considered in medical studies. (It's hard to get reliable data just on long-term effects of the various immediately trans-related treatments). And even if it were, it's so disparate socio-economically from the rest of the population that it's very hard to control for that factor. Add to that the fact that being transgender is a fairly rare condition - 1:11,000 is the usual assumption, 3:1000 is the most generous one I've seen - these particular studies aren't that common.
A proxy for that question is "how do subjects pre/peri/post menopause react to this, with and without hormone therapy (a.k.a contraceptives)". There's mild evidence of hormonal status and COVID response being correlated: https://www.medrxiv.org/content/10.1101/2020.07.30.20164921v...
