Reactional changes in short-term levonorgestrel-releasing intrauterine system (lng-ius) use

Area of Science:

• Reproductive Health
• Gynecology
• Microbiology

Background:

• Intrauterine devices (IUDs) are common contraceptives.
• The levonorgestrel-releasing intrauterine system (LNG-IUS) is a popular IUD option.
• Understanding the effects of LNG-IUS on the vaginal and endocervical environment is crucial for patient counseling.

Purpose of the Study:

• To evaluate changes in the endocervical and vaginal environment in women using a levonorgestrel-releasing intrauterine system (LNG-IUS).

Main Methods:

• A quasi-experimental study involved 60 women undergoing LNG-IUS insertion.
• Vaginal and endocervical pH, bacterioscopy, and Pap smears were assessed before and two months after LNG-IUS insertion.
• Clinical observations included cervical mucus, vaginal discharge, and cervical ectopy.

Main Results:

• Endocervical pH and neutrophil levels increased significantly after LNG-IUS insertion (p=0.02 and p<0.0001, respectively).
• Vaginal cytolysis increased (p=0.04), while vaginal discharge decreased (p=0.01).
• No significant changes were observed in vaginal pH, vaginal infections, or cervical ectopy.

Conclusions:

• Short-term LNG-IUS use is not associated with increased rates of bacterial vaginosis or vulvovaginal candidiasis.
• The LNG-IUS can alter the vaginal and endocervical environment, leading to reduced vaginal discharge.
• These changes occur without affecting the size of cervical ectopy.
