Background : Trichomoniasis was reported to have great influence on pregnancy and fetus health. Since the true epidemiological profile of trichomoniasis profile is not obvious in Kashan, the present study was performed on parturients referring to Shabihkhani hospital, between 2001 and 2002.

Materials and methods : For this descriptive study, initial data were gathered via history, clinical examination, laboratory studies, and culturing.

Results: Of 450 parturients, 2 (0.44%) were revealed to be infected by trichomoniasis. These two had preterm delivery with low birth weight neonates. They both have watery discharge with vaginitis.

Conclusion : Trichomoniasis is not a common infection in Kashan. It is associated with preterm delivery, PROM, and LBW neonate. Meanwhile, clinical picture and laboratory findings can not provide adequate clues for definite diagnosis.
