A pregnancy fetish, also known as maiesiophilia or maieusophoria, is one in which pregnant women are viewed as erotic phenomenons. Those with a pregnancy fetish find pregnant women sexually attractive. This attraction is unique to each person and extends to several stages and experiences of pregnancy such as lactation, impregnation and childbirth. Sometimes, there are fantasies surrounding the circumstances of childbirth, the behavior of pregnant women and the stage of impregnation. There may also be a fascination behind the arousal and gratification of impregnating someone through sex. Erotic lactation may be another component of pregnancy fetish. Women may also have a fetish for being or becoming pregnant.
Pregnancy fetishes may be quite common. A survey of more than 4,000 Americans by Dr. Justin Lehmiller found that 30% had fantasized about getting pregnant or getting someone pregnant; 26% of the group had fantasized about having sex with someone who is already pregnant.
In 2017, Pornhub reported that pregnancy porn searches had risen more than 20% between 2014 and 2017, peaking in 2017. Women were significantly more likely to search for pregnancy porn.
