Contraceptives
Contraceptives
Contraceptives (pronounced: /kɒntrəˈsɛptɪvz/) are methods or devices used to prevent pregnancy. The term is derived from the Latin words contra, meaning "against", and conceptus, meaning "conception".
Types of Contraceptives
There are several types of contraceptives, including:
- Barrier methods: These prevent sperm from reaching the egg. Examples include condoms, diaphragms, and cervical caps.
- Hormonal methods: These prevent ovulation or make it difficult for an egg to implant in the uterus. Examples include birth control pills, patches, and injections.
- Intrauterine devices (IUDs): These are inserted into the uterus to prevent pregnancy.
- Emergency contraception: This is used to prevent pregnancy after unprotected sex or contraceptive failure.
- Sterilization: This is a permanent method of contraception, involving a surgical procedure.
Effectiveness
The effectiveness of contraceptives varies depending on the method used. Some methods, like sterilization and IUDs, are over 99% effective. Others, like condoms and birth control pills, are less effective, especially if not used correctly.
Risks and Side Effects
All contraceptives have potential risks and side effects. These can include hormonal changes, increased risk of certain diseases, and potential complications from surgical procedures. It's important to discuss these risks with a healthcare provider before choosing a contraceptive method.
