Today, let’s dive in a subject a lot of us heard about, but might prefer to ignore… Mpreg! As in, male pregnancy (learn more on the Fanlore page). Yup. As usual, we studied fanfictions that are 10K+ words.
Mpreg is kind of a controversial fanfiction subgenre: people are either fascinated or put off, with very few stance for a middle ground. On AO3, actually a tiny minority of fics are labeled mpreg: in 2015, we counted 1357 fics tagged with mpreg published on AO3, that is 1.9% of the total of 10K words + fics. However, those fics are widely read: they attract way more readers than their number alone would predict.
