Many Young Women Use 'Withdrawal' for Birth Control
But new study confirms that it's not good for preventing pregnancy
One expert who wasn't involved with the study said the reasons that might lead a woman to choose the withdrawal method over something more reliable are complicated.
"Many contraceptives are short-acting and require a lot of action on the part of a woman. Using a condom, having a condom, going to the store or pharmacy to get one. Refilling the pill, taking it every day, getting a prescription refilled. Travel and moving. So many issues make these contraceptive methods difficult to use or to be consistent about," said Dr. Kari Braaten, an obstetrician-gynecologist at Brigham and Women's Hospital, in Boston.
Another expert called the study "nicely done" and said it had important findings.
Dr. Angela Chen, an associate clinical professor of obstetrics and gynecology at University of California, Los Angeles, and the family planning division chief at Ronald Reagan UCLA Medical Center, said it's not at all surprising that people who are using this method have more unintended pregnancies. For the withdrawal method to work successfully, she said both partners need to be highly motivated.
"You need couples who've been together a long time and can communicate well," Chen said. "The woman really needs to understand her menstrual cycles -- when she is most fertile -- and most women do not. Their perceptions are all over the place. An app for fertility tracking can be a good start. Bring your menstrual calendar to your provider to learn more."
She added that the results also suggest that practitioners need to talk about Plan B with their patients more openly. "We should be able to recommend it to anybody on a short-acting contraceptive; anyone who might have a method failure should be offered Plan B."
Study author Dude said the most effective contraception for this age group is a long-acting, reversible method such as an intrauterine device (IUD), or a contraceptive insert in the arm.
But obtaining more effective contraception options -- from long-acting methods to Plan B -- can be difficult for younger women, said Braaten at Brigham and Women's.
"There are certainly issues of access for the age group in this study -- young women ages 15 to 24," Braaten said. "I'd like to stress that one of the things we need to do is improve access to long-acting methods like IUDs and implants, so we minimize these experiences and encounters where women find themselves needing to rely on an 'emergency' form of contraception like withdrawal or Plan B when they're otherwise unprepared."
