Introduction to birth control
Terminology that is used to describe birth control methods includes:
But no matter what terminology, sexually active people can choose from a number of methods to reduce the possibility of their becoming pregnant. Nevertheless, no method of birth control available today offers perfect protection against sexually transmitted infections (sexually transmitted diseases, or STDs), except abstinence.
In simple terms, 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. New methods of birth control are being developed and tested all the time. And what is appropriate for a couple at one point may change with time and circumstances.
Unfortunately, no birth control method, except abstinence, is considered to be 100% effective.
What are barrier methods of birth control (contraception)?
Barrier methods of contraception work by creating a physical barrier between sperm and egg cells so that fertilization cannot occur. The most common forms of barrier contraception are:
Spermicides, a form of chemical contraceptive that work by killing sperm, are often combined with barrier methods of contraception for greater effectiveness.
Barrier methods of contraception generally do not have the side effects of hormonal contraceptives, and some forms of barrier contraception (contraceptive sponges and condoms) may be obtained without a prescription and easily purchased over the counter at pharmacies.
The only medical contraindication to the use of barrier contraception is latex allergy (when using latex condoms). However, with the exception of male and female condoms that can provide some protection against infection with sexually-transmitted diseases (STDs), most methods of barrier contraception are not effective in preventing STDs.
