Forced fatherhood

Forced fatherhood or imposed paternity, occurs when a man becomes a father against his will or without his consent. It can include deception by a partner about her ability to get pregnant or use of contraceptives, birth control sabotage, paternity fraud and sexual assaults of males that result in pregnancy.

"Sperm theft" (also known as "unauthorized use of sperm", "spermjacking" or "spurgling" (a portmanteau of sperm and burgling), refers to a specific form of forced fatherhood where in which a man's semen is used to impregnate a woman without his consent. Although the term uses the word "theft", it more closely falls under a state of fraud or breach of contract. Stealing of sperm in itself without using it for successful insemination is not illegal and is difficult to prove. It usually has no bearing on issues like child support. It is considered an issue in the men's rights movement.
