This article discusses the effectiveness of different types of contraceptives after they have been stopped. Most hormonal contraceptives will become effective within seven days of being discontinued, while the copper intrauterine device (IUD) takes between five and seven days. Barrier methods such as the diaphragm, spermicide and condoms will be immediately effective. Natural methods such as fertility awareness and withdrawal will only be effective if used perfectly every time. The effectiveness of all methods is increased when used consistently and correctly.
Plan B, also known as the morning after pill, is an emergency contraceptive which can be used to prevent pregnancy when taken within 72 hours of unprotected sex. Studies have shown that Plan B is effective in preventing pregnancy after ejaculation in most cases, but the effectiveness decreases the more time that passes after ejaculation. It is also less effective in women who weigh over 176 pounds. It is important to note that Plan B does not protect against sexually transmitted infections and should not be used as a regular form of contraception.
Abstinence education is an approach to sex education which focuses on teaching young people to abstain from sexual activity, typically until marriage. However, there is a debate about whether or not abstinence education is effective. Critics of this approach argue that it does not work because it does not provide young people with information about contraception and safer sex practices. They also claim that it ignores the reality of sexual activity among teens and does not account for the fact that some teens will become sexually active regardless of abstinence education. Proponents of abstinence education believe that it is the most effective approach to sex education, as it encourages teens to delay sexual activity and make responsible decisions. Ultimately, it is up to individual schools and communities to decide which approach they feel is most beneficial.
