Cervical smear evaluations in 3,374 women using various contraceptives showed a low incidence of dysplasia, with most cases regressing. The CuT380 Ag intrauterine device (IUD) appears promising for long-term use.

Area of Science:

  • Gynecology
  • Reproductive Health
  • Cytopathology

Background:

  • Cervical cytology screening is crucial for early detection of precancerous lesions.
  • Evaluating the impact of different contraceptive methods on cervical health is essential for patient safety.

Purpose of the Study:

  • To assess the cytologic changes in cervical smears among women using various contraceptive methods.
  • To compare the incidence of cervical dysplasia with different types of contraceptives and pretreatment levels.

Main Methods:

  • Cytologic evaluation of cervical smears from 3,374 women over 6 months to 15 years.
  • Analysis of dysplasia incidence associated with Lippes loop, copper T200, CuT380 Ag, levonorgestrel IUDs, injections, and subdermal implants.
  • Comparison of post-treatment dysplasia rates with pretreatment rates.

Main Results:

  • No severe dysplasia or malignancy was observed with any contraceptive.
  • An overall 3.3% incidence of mild to moderate dysplasia was noted, statistically similar to the pretreatment rate (1.4%).
  • Higher copper content devices and CuT200 showed a higher incidence of dysplasia compared to others; CuT380 Ag had a low incidence (1.5%).

Conclusions:

  • Most dysplastic smears showed regression, with persistence requiring contraceptive discontinuation.
  • The CuT380 Ag intrauterine device (IUD) demonstrates promise due to its low dysplasia incidence up to 5 years.
  • Long-term follow-up in larger cohorts is needed to confirm the safety of CuT380 Ag.
