What is the effectiveness rate of abstinence in preventing pregnancy?

Abstinence is considered the only method of contraception that is 100% effective in preventing pregnancy when practiced consistently and correctly. This means that if an individual or couple abstains from any sexual activity, there is no chance of sperm fertilizing an egg, thereby eliminating the possibility of pregnancy.

The effectiveness of abstinence hinges on the commitment to refrain from sexual intercourse entirely, as any sexual activity carries some level of risk for pregnancy. Although other methods of contraception can significantly reduce the likelihood of pregnancy, they often come with failure rates due to incorrect use or misuse. In contrast, abstinence, when adhered to without exceptions, leaves no room for such risks, thus ensuring complete prevention.
