User blog comment:Bunai82/VOCALOID - female to male ratio/@comment-53539-20140425182656

without English, Korean, Spanish English and Bilingual, you can see the problem isn't so much of too many females, but the Japanese otaku culture demanding females more and more.

Look at every studio for Japanese Vocaloid, they have a female vocal as their top vocaloid; Gumi, Miku, Lapis, IA. The top 3 most popular Vocaloids to be uploaded works for on NND are Miku, Gumi and Rin... And despite there being males this gen, none of them hit it off with Gakupo not even being near as popular as he was in V2, and Kaito being the only really successful male so far.

The issue is just that in Japan, the Otaku culture means female mascots dominate everything. Outside of Luffy and Chopper for One Piece, I remember noting how popular the female figurines were over all other males, which although were didn't sell quickly. This isn't just restricted to OP either, but many, many anime and manga series are subject to this. You female mascots for everything from food to electronic stuff. Naturally, Vocaloid is caught up in all of this.

But don't get me wrong, Japan isn't an isolated case of this. Sex sells (though too much sex is known to put people off), so even in American culture... I know a lot of comic book and game characters have merch centred around at least 1 female character. Outside of a few popular males that will sell for DC comics, I know a supergirl model has more of a chance to sell then many males of her equal popularity. Ditto, its the same for wonder woman, batgirl, etc, etc. :-/

So at the end of the day, the issue so much of a poor female to male ratio, but simply that when males do come along, they'll never be able to compete on par with the current females. Its not just the fact of the geek/nerd culture being mostly centred around males, but the fact that Vocaloid overlaps a culture aspect where females are just preferred. Even in the music industry... Outside of popular boybands, attractive female singers sell better then males.
