Nah, it's ok, I got this.
Kurogane Ken, Minamoto Hisanari, Kurata Uso, Yatosaki Haru, Randou House, Ikeda Takashi, Satou Nanki, Ryuunosuke, Touge Hiro, Hachiko, Naoya Ishikawa, Miyabi Fujieda (i think?), Mitsumoto Jouji, Kogaku Kazuya, Keito Koume, moonexplorers, Kishi Torajiro, Heebee, Mikage Sekizai and Michairu.
While it is probably true that the majority of big influential yuri series, like Girlfriends or Yuru Yuri, are drawn by females, there's also a lot of men in it too. But more importantly, there's a huge amount of males in the doujin scene, I would say probably a lot more than ladies due to the huge amount of NSFW doujins out there.
Main problem there tho, is that details on genders for artists like that, or even genders for a lot of artists behind big series (I'm not even confident on Miyabi's gender), are pretty hard to come by or be certain of. Like, I'd assume Homura Subaru is male, because look at it. But are they? Dunno.
So yeah, there's a lot of dudes, and there's a lot of girls. Probably more girls in the serialised end of things, but probably more guys on the fanwork side.
