Contraceptives

Contraception: Complete Detailed Guide with FAQs

Introduction

  • Contraception refers to methods or devices used to prevent pregnancy.
  • Options include hormonal, barrier, natural, and permanent methods, offering flexibility for individual needs.
  • Choosing the right contraceptive depends on factors like health, lifestyle, age, and reproductive goals.

Types of Contraception

1. Hormonal Contraception

  • Alters hormonal levels to prevent ovulation, thicken cervical mucus, or thin the uterine lining.
  • Examples:
    • Combined Oral Contraceptive Pill (COC): Contains estrogen and progestin.
    • Progestin-Only Pill (POP): Suitable for breastfeeding women or those intolerant to estrogen.
    • Injectables: Depo-Provera (medroxyprogesterone acetate) lasts 3 months.
    • Implants: Etonogestrel implant (e.g., Nexplanon) effective for up to 3 years.
    • Patches: Transdermal patch (e.g., Xulane) replaced weekly.
    • Vaginal Rings: NuvaRing, worn for 3 weeks per cycle.

Advantages:

  • High efficacy.
  • Regulates menstrual cycles.

Disadvantages:

  • May cause nausea, weight gain, or mood changes.
  • Increased risk of blood clots (for COCs).

2. Barrier Methods

  • Physically block sperm from reaching the egg.
  • Examples:
    • Condoms: Male and female options; also protect against sexually transmitted infections (STIs).
    • Diaphragms: Dome-shaped devices used with spermicide.
    • Spermicides: Chemical agents that kill sperm; used alone or with other methods.

Advantages:

  • No hormones involved.
  • Protect against STIs (condoms only).

Disadvantages:

  • Less effective if not used correctly.
  • Some may cause irritation.

3. Intrauterine Devices (IUDs)

  • Inserted into the uterus by a healthcare provider.
  • Examples:
    • Hormonal IUDs: Release progestin (e.g., Mirena, Kyleena) for 3–6 years.
    • Copper IUDs: Non-hormonal, effective for up to 10 years (e.g., Paragard).

Advantages:

  • Long-term, reversible, highly effective.
  • Minimal maintenance.

Disadvantages:

  • May cause cramping or irregular bleeding.
  • Requires professional insertion and removal.

4. Emergency Contraception (EC)

  • Prevents pregnancy after unprotected sex.
  • Examples:
    • Levonorgestrel Pill: Plan B, effective within 72 hours.
    • Ulipristal Acetate (Ella): Effective within 5 days.
    • Copper IUD: Can be inserted within 5 days for emergency contraception.

Advantages:

  • Prevents pregnancy after unexpected situations.

Disadvantages:

  • Not a regular contraceptive method.
  • Less effective than routine contraception.

5. Natural Methods

  • Involve tracking fertility and avoiding intercourse during fertile windows.
  • Examples:
    • Fertility Awareness-Based Methods (FABMs).
    • Withdrawal (pull-out method).
    • Lactational Amenorrhea Method (LAM): Effective in breastfeeding mothers.

Advantages:

  • No hormones or devices needed.

Disadvantages:

  • High failure rate with improper use.
  • Requires discipline and accurate tracking.

6. Permanent Methods

  • Irreversible surgical procedures for long-term prevention of pregnancy.
  • Examples:
    • Female Sterilization (Tubal Ligation): Blocks or seals fallopian tubes.
    • Male Sterilization (Vasectomy): Cuts or seals vas deferens.

Advantages:

  • Permanent solution.
  • No ongoing maintenance.

Disadvantages:

  • Requires surgery.
  • Not easily reversible.
