Mpreg is the acronym for male pregnancy. It is a plot device where males, usually homosexual and cis, can be impregnated by their partners. Many examples of it can be found in actual television shows like Star Trek: Enterprise, Farscape, and Alien Nation.[1] In these particular cases, mpreg is usually explained away through ‘alien biology’ or the use of futuristic technology. However, in fanfiction, there are many different explanations used for the occurrence of mpreg (including the ever popular ‘it’s just a thing that happens’). Medical experimentation, magic, or the existence of an Alternate Universe, are the most common explanations used. Recently, the Alternate Universe explanation has given way to the Omegaverse and its A/B/O hierarchy where male pregnancy can occur through Omega and/or Beta males.
