This work is a User Manual for a fictional reproductive system implanted in human hands. The system is designed to break from the universal patriarchal essentialism and reconstruct a utopian mode of gender determination while acknowledging the nature sex polarity. The manual depicts the absurd design as a serious product filled with sarcasm and black humour. It discusses the females’ relationship with desire and body rights, and the possibility of seeking the autonomy of sexual attributes. The manual’s roots are in the concept of cohabitation in technoculture and Donna Haraway’s Cyborg Manifesto, where it rethinks what the nature determines and what the society determines.
