From poking holes in condoms to stealing birth control pills, some men are doing it all to get their partners pregnant.
The sex trend is being called "reproductive coercion" by the doctors and new research suggests that it is not just young women involved in abusive relationships who are at risk as previously believed.
Rebecca Levenson of Futures Without Violence, which helps educate doctors about the unique form of abuse said that women have come to tell her that their partner took their IUD out or took her money so she is unable to buy birth control pills, the New York Daily News reported.
641 women between the ages of 18 and 41 were surveyed and determined that 16 percent had experienced partners tampering with their birth control.
Among those women, about 1 in there suffered violence at the hands of their partner.
Levenson said - in words of one woman - men do this so can keep them in their life forever.
