Traditionally, the rhythm method consists of a woman keeping track of her menstrual cycle. That 12-day window takes into account the 24-hour lifespan of an egg and the five-day survival rate of sperm.
A previous study showed that the method was more than 95 percent effective at preventing pregnancy, which is a higher success rate than contraceptive devices like condoms or diaphragms. The new research, published in the October issue of the Journal of Family Planning & Reproductive Health Care, found that more than 1,600 women indicated they would likely continue to use the method.
