Birth Control (cont.)

Summary and conclusions

Many methods of birth control and contraception are available today. There are many options. Unfortunately, most of these choices offer little or no protection against sexually transmitted infections (sexually transmitted diseases, STDs), especially against HIV, the human immunodeficiency virus that causes acquired immunodeficiency syndrome (AIDS).

For some individuals, economic considerations dictate their choice of contraceptive method. Abstinence is 100% effective and costs nothing, but may not always be a popular choice. "Natural" methods cost essentially nothing (if one does not use test kits or electronic monitors) but they require considerable discipline to be effective. Barrier methods, such as spermicides and condoms, are affordable to most people and can be effective if they are used consistently and correctly. The hormonal methods, such as "the pill," are highly effective but their cost can add up if they must be purchased over a period of time.

The choice of a particular method of contraceptive also depends on a person's age, health, and personal situation. For example, behavioral methods (fertility awareness or withdrawal), IUDs, and tubal ligation are not contraceptive methods recommended for teenagers. Surgical sterilization (vasectomy or tubal ligation) is not appropriate for a man or woman who wishes to have children in the future because surgical reversal is not guaranteed. Certain medical conditions can be contraindications for a woman using a hormone-based method of birth control.

Birth Control At A Glance

  • Methods of birth control include barrier, mechanical, hormonal, and natural methods, as well as emergency and permanent methods.
  • All methods of birth control are based on either preventing a man's sperm from reaching and entering a woman's egg (fertilization) or preventing the fertilized egg from implanting in the woman's uterus (her womb) and starting to grow.
  • No birth control method, except abstinence, is considered to be 100% effective.
  • No method of birth control available today offers perfect protection against sexually transmitted infections (sexually transmitted diseases, or STDs), except abstinence.
