2 in 5 Women Do Not Regularly Use Birth Control | A new study sponsored by the pharmaceutical company Teva reveals that, over the last month, only three out of five women of childbearing age used birth control. The other two of five believed they were unable to get pregnant, or were not currently sexually active. The Contraception in America study also found that 43 percent of women who’d been pregnant had an unintended pregnancy — of those, 50 percent said they’d gotten pregnant through failed birth control methods like broken condoms. These numbers are on par with other studies on unintended pregnancy and contraceptive use, and reveal the need for further access to and education about the most effective forms of contraceptives. The poll asked 1,000 women between the ages of 18 and 49 about their reproductive health, and 201 doctors about the contraceptive use of their patients.
