The aim of emergency contraception is to prevent fertilisation (emergency hormonal contraception) or implantation (copper coil). Emergency hormonal contraception is more widely available and easier to access (for example from pharmacies); however, the copper coil is much more effective at preventing pregnancy after unprotected sex. This is because emergency hormonal contraception is only likely to be effective before ovulation, whereas the coil can be fitted at any time up to 5 days after ovulation, and left in place for ongoing contraception. The copper coil can be obtained through community sexual health services/genitourinary medicine clinics or some general practices.
