classical and molecular methods for evaluation of chlamydia trachomatis infection in women with tubal factor infertility

background: chlamydia trachomatis is the most reported bacterial sexually transmitted disease, especially among young women worldwide. aim of this study was comparison to evaluate the prevalence of chlamydia trachomatis infection in woman with tubal infertility by means of pcr and cell culture techniques. methods: fifty-one women with confirmed tfi were enrolled in this study in (avicenna infertility clinic) between january 2010 and january 2011. cervical swab and cytobrush specimens were collected from each patient by gynecologists and sent to laboratory in transport media. detection of chlamydia trachomatis in samples was performed using pcr and bacteria culture in maccoy cell line. the data were analyzed by fisher’s exact test and independent t-test. statistical significance was established at a p-value <0.05. results: a significant relation was observed between increased the age of first intercourse and chlamydial infection. six (11.7%) samples had positive pcr result, whereas cell culture results were positive in only 2 (3.9%) samples. a significant relation was also identified between the duration of infertility and infection (p<0.05) by pcr versus cell culture method. conclusion: the results showed that pcr is a rapid method, compared to cell culture for detecting chlamydial organism. it also became clear that the age at first intercourse is important to predict the likelihood of chlamydia trachomatis.
