Regarding this discussion, I lived in Japan for quite a while and in my observation both men and women consume yuri content but the types of yuri they consume tend to vary.
Men usually being more into, maybe contrary to expectations??? stuff that is much more moe oriented fluff and class S type stuff (or, yes, smut, but those are two different demographics of male fans!). A lot of the yuri and yuri adjacent series liked by men were more of the 4koma type comedy cute girls doing cute things vibe like Yuru Yuri, or series like Madoka with yuri undertones but not so much explicit romance content. In general cute stuff with cute girls they can ship with each other, it's tied with moe culture. Yuri is seen as more pure and lets them play with romance tropes without ruining the cgdct atmosphere with male characters. See also, idols are allowed to yuribait and flirt with each other all they want and the fans love it, but god forbid any of them talks to a man or gets a boyfriend.
On the other hand, more romance oriented series and dramas are primarily consumed by women, which isn't really a surprise right? Given that romance in general tends to be a very stereotypically female-oriented genre to begin with. Especially one about queer women with no male PoV character. Yuri stems from shoujo after all. Also, you can just tell usually when reading a manga right, when it's being written by a woman for women, it just has a vibe. Like I could imagine someone ignorantly looking at Asumi-chan and assuming it's meant for men based on the premise but when you read it it's just so clearly girlcoded in an unquantifiable way
When it comes to polls I think you have to really contextualize the conclusions you draw from them. Like we have to take into account sampling bias and also which yuri are being read by who. Depending on which specific type of yuri you're looking at the results are probably all over the board. Like I suspect there's a similar effect happening to the "women are the majority of gamers" polls, where it might be true but a lot of those women are mostly just playing mobile games and 400 hours of Animal Crossing, while when you look at the more 'hardcore' gamers as we traditionally imagine the idea, it skews male instead. And when it comes to online polls, I imagine they skew more male than the average too just because users on manga websites in general probably skew more male than the average.
