Which contraception method is considered most effective in preventing unplanned pregnancies?

The method recognized as the most effective in preventing unplanned pregnancies is the Implanon, a form of long-acting reversible contraception. Implanon is a small rod implanted under the skin of the upper arm, which releases hormones to prevent ovulation. Its effectiveness is largely due to its ability to provide continuous contraception without the need for daily attention, as seen with oral contraceptive pills, or reliance on usage during sexual activity, such as with condoms.

Implanon has a failure rate of less than 1%, making it one of the most reliable contraceptive options available. In contrast, while the emergency contraceptive pill can prevent pregnancy after unprotected intercourse, it is intended for occasional use and is not as effective as a primary method of contraception. Regular contraceptive methods, like the oral pill and condoms, also have higher failure rates due to human error or inconsistency in use. Therefore, Implanon stands out as the most effective choice for continuous pregnancy prevention.
