Many women may think birth control pills and condoms are better at pregnancy prevention than they actually are, a new study suggests. Researchers found that of more than 4,100 women who were seeking birth control, about 45 percent overestimated the effectiveness of the Pill and condoms. They also had too much faith in hormonal birth control patches, vaginal rings and injections, according to findings reported in the American Journal of Obstetrics and Gynecology. The findings point to a need for better education on how well different birth control methods work with “typical use” in the real world, study leader Dr. David L. Eisenberg told Reuters Health.
