Reuters reports a new study published in the journal Contraception which found that up to 17 percent of young Americans may be using “withdrawal” as a method of preventing pregnancy, but may be using other methods as well. The authors gathered data from 1,607 young men and 1,849 young women who were sexually active, not trying to get pregnant, and not sterile or infertile. For both genders, those who felt that condoms would lessen their sexual pleasure were more than twice as likely to have used withdrawal. While Planned Parenthood says that pulling out can work up to 96 percent of the time, the CDC does not recognize this as an effective form of birth control. These findings suggest a need to address the misunderstandings about the effectiveness of various contraceptive methods.
