Since the comment I am replying to is being upvoted, I will put a little more effort into explaining. “Getting 20 to 30 minutes of strong sun on my bare arms and legs and eyes every other day” is from neuroscientist Andrew Huberman. This effect of UVB light on the sex hormones seems to have been recently discovered; more information here.
That’s an interesting paper! Although it seems a bit confounded—“Because eyes of mice and of human volunteers were not covered, we cannot exclude the possibility that solar/UV radiation to the eye affected the observed sexual behavior.” Which would be interesting if true, suggesting that just being outside and getting UV light in the eyes would be the thing to do. I guess you note this at the end of your first comment.
What do you think about the potential skin aging effects of UV vs the potential health benefits?
Note that this is a reply to myself.

https://www.sciencedirect.com/science/article/pii/S1015958423001392 suggests that bright light might be causing the effect, not UV.
