Contraception

Contraception refers to the use of various methods and devices to prevent pregnancy. The goal of contraception is to prevent fertilization of an egg by a sperm or to prevent a fertilized egg from implanting in the uterus.

Types of Contraception

• Hormonal Methods: These methods use hormones to prevent ovulation, thicken cervical mucus to block sperm, or thin the lining of the uterus to prevent implantation. Examples include:
  • Birth control pills (oral contraceptives)
  • Patch (transdermal patch)
  • Vaginal ring
  • Injectable contraceptives (e.g., Depo-Provera)
  • Implantable contraceptives (e.g., Nexplanon)
• Barrier Methods: These methods physically prevent sperm from reaching the egg. Examples include:
  • Male condoms
  • Female condoms
  • Diaphragm
  • Cervical cap
• Intrauterine Devices (IUDs): These devices are inserted into the uterus to prevent fertilization or implantation. Examples include:
  • Copper IUD (e.g., ParaGard)
  • Hormonal IUD (e.g., Mirena, Skyla)
• Sterilization: These methods permanently prevent pregnancy by surgically blocking the fallopian tubes or vas deferens. Examples include:
  • Tubal ligation (female sterilization)
  • Vasectomy (male sterilization)
• Natural Family Planning: These methods involve tracking the menstrual cycle and fertility to avoid pregnancy. Examples include:
  • Fertility awareness-based methods (FABMs)
  • Basal body temperature method
  • Cervical mucus observation

Effectiveness of Contraception

The effectiveness of contraception varies depending on the method used. The most effective methods are:

• Implantable contraceptives (99% effective)

Risks and Benefits of Contraception

Contraception can have both benefits and risks. Benefits include:

Risks and side effects may include:

• Hormonal changes
• Weight gain or loss
