Birth control sabotage

Birth control sabotage refers to efforts to manipulate another person's use of birth control or to undermine efforts to prevent an unwanted pregnancy. Examples include replacing birth control pills with fakes, puncturing condoms and diaphragms, or using threats and violence to prevent an individual's attempted use of birth control. A related concept, contraceptive fraud, is intentional misrepresentation regarding the use of or need for birth control. Both of these are forms of reproductive coercion.

The sabotage or fraud may be practiced by either sexual partner, or by a third party.

Domestic violence
Birth control sabotage is frequently associated with physical or sexual violence, and is a contributor to high pregnancy rates—especially teenage pregnancy rates—among abused, disadvantaged women and teenagers.

Studies on the birth control sabotage performed by males against female partners have indicated a strong correlation between domestic violence and birth control sabotage. These studies have identified two main classes of the phenomenon:
 * Verbal sabotage—verbal or emotional pressure not to use birth control or to become pregnant.
 * Behavioral sabotage—the use of force to have unprotected sexual intercourse or not to use birth control.
