ECPs Reduce the Risk of Pregnancy by up to 95 Percent, and Emergency Contraception IUD Insertion Reduces the Risk by 99.9 Percent.
Two time factors influence the efficacy of ECPs: the amount of time elapsed after unprotected intercourse, and the point in a woman's cycle at which she had sex. The earlier ECPs are taken after unprotected intercourse, the more effective they are (TFPMFR, 1998). The closer a woman is to ovulation at the time of unprotected intercourse, the less likely the method will succeed (Stewart, et al., 2004). ECPs are not as effective as correct and consistent use of precoital, reversible contraceptive methods such as the pill, IUD, or contraceptive implants, injections, patches, or rings, and they do not protect against sexually transmitted infections (Knowles & Ringel, 1998; Roumen, et al., 2001; Zieman, et al., 2002).
The Yuzpe regimen of combined estrogen and progestin ECPs reduces the risk of pregnancy by roughly 75 percent if started within 72 hours of unprotected intercourse. Not every woman at risk of pregnancy actually becomes pregnant. On average, only eight out of 100 women will become pregnant after having unprotected sex during the second or third week of their menstrual cycles. But if they take ECPs, only two out of those 100 women will become pregnant. Combined hormonal ECPs thus reduce the risk of pregnancy by roughly 75 percent, preventing six of eight likely pregnancies (Knowles & Ringel, 1998; OPR, 2005; Rodrigues, et al., 2001; Stewart, et al., 2004).
When used within 72 hours of unprotected intercourse, progestin-only ECPs were found to reduce the risk of pregnancy by 89 percent in a World Health Organization-supported study involving nearly 2,000 women in 21 clinics around the world. When taken within 24 hours of unprotected intercourse, they were found to reduce the risk of pregnancy by 95 percent ("FDA Approves...," 1999; TFPMFR, 1998).
More than 9,400 copper-bearing IUDs have been inserted postcoitally since 1976, with only ten pregnancies occurring: a rate of fewer than one in 1,000, reducing the risk of pregnancy by more than 99 percent (OPR, 2005; Stewart, et al., 2004).
