Birth Control :: Contraceptives, Birth Control Essays
The practice of birth control prevents conception, thus limiting reproduction. The term birth control, coined by Margaret SANGER in 1914, usually refers specifically to methods of contraception, including STERILIZATION. The terms family planning and planned parenthood have a broader application. METHODS OF BIRTH CONTROL Attempts to control fertility have been going on for thousands of years. References to preventing conception are found in the writings of priests, philosophers, and physicians of ancient Egypt and Greece. Some methods, though crude, were based on sound ideas. For example, women were advised to put honey, olive oil, or oil of cedar in their vaginas to act as barriers. The stickiness of these substances was thought to slow the movement of sperm into the uterus. Wads of soft wool soaked in lemon juice or vinegar were used as tampons, in the belief that they would make the vagina sufficiently acidic to kill the sperm. The Talmud mentions using a piece of sponge to block the cervix, the entrance to the uterus. Sperm Blockage Several modern methods of birth control are practiced by creating a barrier between the sperm and the egg cell. This consists of the use of a chemical foam, a cream, or a suppository. Each contains a chemical, or spermicide that stops sperm. They are not harmful to vaginal tissue. Each must be inserted shortly before COITUS. Foams are squirted from aerosol containers with nozzles or from applicators that dispense the correct amount of foam and spread it over the cervix; creams and jellies are squeezed from tubes and held in place by a diaphragm or other device; and suppositories--small waxy pellets melted by body heat--are inserted by hand. More effective at keeping sperm and egg apart are mechanical barriers such as the diaphragm and cervical cap (both used with a spermicide), the sponge, and the condom. A diaphragm is a shallow rubber cup that is coated with a spermicide and positioned over the cervix before intercourse. Size is important; women need to have a pelvic examination and get a prescription for the proper diaphragm. The cervical cap, less than half the size but used in the same way, has been available worldwide for decades. It was not popular in the United States, however, and in 1977 it failed to gain approval by the Food and Drug Administration (FDA); in 1988, the FDA again permitted its sale. The contraceptive sponge, which keeps its spermidical potency for 48 hours after being inserted in the vagina, was approved in 1983. Like the diaphragm and cervical cap, the sponge has an estimated effectiveness rate of about 85%. The devices only rarely produce side effects such as irritation and allergic reactions and, very rarely, infections. The condom, a rubber sheath, is rolled
