As another comment above pointed out. With roughly equal number of men and women, I would naively think that if men are lonely, so are women.
Is loneliness specific to male actually documented?
Two problems can be real while having different solutions proposed for them.
“AI companion” sounds like a weird solution but it sounds less weird specifically for men. For cultural or whatever reasons.
Second link is that one:

> Our analyses show that women were more lonely than men also in adjusted analyses.
I don’t have the background to judge that study and I take social science studies with a huge grain of salt. For now, I will just stick to “I don’t know” then.
