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.
