Trichomonas vaginalis in vaginal smears of women using intrauterine contraceptive device.
Pak J Med Res Jan ;44(3):114-6.

Aims: To detect the association between the use of an intrauterine contraceptive device (IUCD) and the presence of Trichomonas vaginalis (Tv) in the vaginal smears. Study design and setting: Vaginal smears were collected from 800 women who attended the Gynaecology and Obstetrics unit at Federal Government Hospital (Polyclinic) Islamabad, between June 1995 – June 1997. Results: Among 45 IUCD users, 15 women were positive for Tv (33.33%). Forty two of 755 non-users were also positive for Tv (5.56%). There was a significant correlation between the use of IUCD and the presence of Tv (p<0.05). The data also indicated that the prolonged use (>3 years) of copper-IUCD may promote the growth of Tv in the vaginal mucosa. Conclusion: The use of copper IUCD for a long period causes growth of Tv on the genital mucosa so special attention should be paid to women who have prolonged copper-IUCD for the possible presence of Tv.
