Artificial Contraceptives and Natural Family Planning
Artificial contraception, also known as birth control, are medications used to prevent pregnancy. The primary type of artificial contraception is the birth control pill.
Types:
Mechanical Devices – materials that are inserted or fitted to the reproductive system to prevent pregnancy. Such mechanical devices are condoms, which are inserted to the male genitalia, diaphragm, which is inserted to the female genitalia, and other devices.
Hormonal Methods - There are various delivery methods for hormonal contraception. Forms of synthetic oestrogensand progestins (synthetic progestogens) combinations commonly used include the combined oral contraceptive pill ("The Pill"), the Patch, and the contraceptive vaginal ring ("NuvaRing"). A monthly injectable form, Lunelle, is not currently available for sale in the United States.
Other methods contain only a progestin (a synthetic progestogen). These include theprogesterone-only pill (the POP or 'minipill'), the injectables Depo Provera (a depot formulation ofmedroxyprogesterone acetate given as an intramuscular injection every three months) and Noristerat (Norethindrone acetate given as an intramuscular injection every 8 weeks), and contraceptive implants.
Chemical methods – involves usage of chemically-prepared substances to disrupt the sperms. Spermicides are one example.
