In one year, only two of every 100 couples who use condoms consistently and correctly will experience an unintended pregnancy—two pregnancies arising from an estimated 8,300 acts of sexual intercourse, for a 0.02 percent per-condom pregnancy rate.[3]
In one year with perfect use (meaning couples use condoms consistently and correctly at every act of sex), 98 percent of women relying on male condoms will remain pregnancy free. With typical use, 85 percent relying on male condoms will remain pregnancy free.[3]
In one year with perfect use, 95 percent of women relying on the female condom will remain pregnancy free. With typical use, 79 percent relying on female condoms will remain pregnancy free.[3]
By comparison, only 15 percent of women using no method of contraception in a year will remain pregnancy free.[3]
