The copper-7 intrauterine contraceptive device: 5-year evaluation

Area of Science:

• Family Medicine
• Reproductive Health
• Contraception

Background:

• Intrauterine contraceptive devices (IUDs) are a common form of reversible contraception.
• The copper-7 (Cu-7) IUD is one type of IUD used for birth control.

Purpose of the Study:

• To evaluate the efficacy and safety of the copper-7 (Cu-7) intrauterine contraceptive device (IUD) in a family practice setting.
• To assess continuation rates, pregnancy rates, expulsion rates, and return of fertility after Cu-7 IUD use.

Main Methods:

• A family practitioner inserted copper-7 (Cu-7) intrauterine contraceptive devices (IUDs) in 134 women over a 5-year period.
• Data collected included rates of continued use, accidental pregnancy, expulsion, and post-removal fertility.

Main Results:

• Continuation rates after 2 years were 53.0% for the first IUD and 63.9% for all IUDs.
• The accidental pregnancy rate was 2.4%, and the expulsion rate was notably low at 0.8%.
• Fertility returned to normal for women desiring pregnancy after IUD removal.

Conclusions:

• The copper-7 (Cu-7) IUD is an acceptable contraceptive option in family practice when inserted with careful technique and conscientious follow-up.
• Low expulsion rates and maintained fertility suggest the Cu-7 IUD is a safe and effective long-term contraceptive choice.
