A more thorough explanation:

Definition: Birth control refers to any method used to prevent pregnancy. This can be achieved through mechanical or chemical means, or by abstaining from sexual intercourse. Contraception is a more specific term used to describe birth control methods.

Examples:

• Condoms
• Birth control pills
• Intrauterine devices (IUDs)
• Diaphragms
• Spermicides
• Tubal ligation (surgical sterilization)
• Vasectomy (surgical sterilization)

These examples illustrate the different types of birth control methods available. Condoms and diaphragms are mechanical methods that physically prevent sperm from reaching the egg. Birth control pills and IUDs are chemical methods that alter hormone levels to prevent ovulation or implantation. Spermicides are chemicals that kill sperm. Tubal ligation and vasectomy are surgical methods that permanently prevent pregnancy by blocking or cutting the fallopian tubes or vas deferens.
