You know how Ironmouse was crying and shaking at the thought of two streamers asking her what she looked like? Yeah, VTubers are often uncomfortable with the spotlight, hence they don’t show their actual faces or discuss their actual lives on stream. Instead, they use an underage, sexualized avatar. They’re shy, okay!?
Seriously, though. VTubers are pretty private about their personal lives, which is why it’s quite disturbing that there is a website dedicated to tracking VTubers’ ovulation. Even without any avatar skin in the game, I can most definitely say this is quite the invasion of privacy and truly icky.
How (AND WHY!?) are perverts tracking VTubers’ periods?
This creepy fertility tracking website, which I feel I shouldn’t link to, apparently uses context clues to speculate whether a female-presenting VTuber is having her period or not. This could be a comment made during a stream or a tweet shared on X.
A single screenshot from the site’s observation area suggests the ovulation cycles on the website are not very accurate. Any mention of being tired, getting a headache, or feeling sick apparently is enough to make these chronically online losers assume a woman has her period.
Selecting a single VTuber to check their calendar out also raises another accuracy issue with this kind of website. Not that anyone thought it was actually reliable. Still, journalism.
Anyway, the calendars clearly just assume that a female VTuber has her period at the same time every month, following a very consistent pattern. This doesn’t account for any irregularities in a woman’s cycle.
And now, the why. Of course, we can’t truly know the motivation of an anonymous freak online who spends time thinking about cartoon women’s ovulation cycles. However, I can make an educated guess along with many other concerned VTubers: this person has a breeding fetish.
The website’s inclusion of “ovulating VTubers” and “fertile VTubers” as categories makes it very likely that the person behind the website has a fantasy of impregnating and controlling the women on the site. The desperation to obtain personal information against their will is another sign that this person is deriving pleasure from this fantasy.

It may seem harmless – maybe even funny – but it’s yet another attempt at normalizing the stalking and invasion of privacy that female streamers experience. I think we can agree that it’s not exactly normal to want to know when the person behind a child-like avatar is getting period cramps. It’s weird.
I’m not gonna knock anyone’s fetish. But it’s one of those instances where the fetish should be kept private. Maybe write about your obsession with impregnating a VTuber in a diary. Maybe get a therapist. Don’t make a website where we can see your every obsessive observation and invasive behavior.
It’s stuff like this that makes me actually sympathize with Ironmouse’s alleged mental breakdown at The Streamer Awards when asked “invasive” questions about her actual identity behind the screen. Can’t a woman pretend to be a jiggly tween cartoon in peace in 2026?
