Comparing IUDs and Implants

Contraceptive Effectiveness of IUDs/Implants

  • IUD: IUDs typically contain either copper or hormones, preventing sperm from reaching the egg and reducing the chance of fertilization. The effectiveness is over 99%.
  • Implant: The implant releases progestin hormone, thickening cervical mucus and inhibiting ovulation. The effectiveness is up to 99.95%.

Pros and Cons of IUDs

  • Pros: Long-lasting effectiveness (5-10 years), no need for frequent interventions.
  • Cons: May increase menstrual bleeding, cause abdominal pain, and carry a rare risk of infection or uterine perforation.

Pros and Cons of Implants

  • Pros: Convenient, does not affect sexual intercourse, and works quickly (within 7 days).
  • Cons: May cause menstrual irregularities, hormonal side effects, and higher costs compared to IUDs.
