New research says a birth control method that tracks a woman's 12-day "fertile window" is more effective than a condom at preventing pregnancy.
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.
Those seeking an easy way to track their "window" can opt to use CycleBeads. Developed by the Institute for Reproductive Health, each of the 32 color-coded beads on this string represents a day of the menstrual cycle.
Here's how it works: The woman moves a small rubber ring over the bead that represents her current "day." The first day of her period is signified by a red bead. The following brown beads mean pregnancy is very unlikely. Beads 8 through 19 are glow-in-the-dark white, but act as a "red flag" to represent fertile days.
