Background: Ureaplasma urealyticum is known as a sexually transmitted agent, described as possible cause of acute pyelonephritis, PID (Pelvic Inflammatory Disease), chorioamnionitis, urethritis, respiratory distress syndrome, pneumonia in newborn, abortion and infertility. Ureaplasma urealyticum infection not only jeopardizes fertility but also poses a risk for infertility treatment and resulting pregnancies. The purpose of this study was to determine the frequency rate of ureaplasma urealyticum in infertile women.

Materials and Methods: Specimens were taken from 312 patients, aged from 17 to 45 years. The characteristics of patients, clinical symptoms, and history of abortion were recorded. 312 endocervical swab samples were taken, and placed immediately in transport medium. Cultures were done in U broth and U agar supplemented with urea.

Results: Ureaplasma urealyticum was identified in 15% (47) of the infertile women. The isolation rate of Ureaplasma urealyticum in young women was higher than the others (<28 age).

Conclusion: Because of the potential adverse effects of the Ureaplasma urealyticum on the success rate of highly specialized infertility treatment, it is necessary to check this organism in infertile women
