Infertility in female is one of the most important sequelae of sexually transmitted infections (STIs). Neisseria gonorrhoeae and
Chlamydia trachomatis are the predominant agents causing infertility. Pathogenesis of Mycoplasma genitalium and Ureaplasma
urealyticum remain to be addressed. Asymptomatic carrier is serious epidemiological problem because of unconscious
infection to sexual or perinatal transmission. Therefore accurate and timely diagnosis is essential for treatment to prevent
transmission and infertility. Advantage of real-time PCR (RTPCR) is to combine detection and quantitation simultaneously.
The aim of study was to screen N. gonorrhoeae, C. trachomatis M. genitalium and U. urealyticum in infertile and healthy
women. 248 women (98 infertile and 150 healthy) attending the gynaecology clinics were included in the study after excluding
other causes of infertility. ECS and endometrium tissue were tested by RTPCR using gene PorA of N. gonorrhoeae, cryptic
plasmid of C. trachomatis, MgPa of M. genitalium and urease of U. urealyticum. Sequencing was done on these specimens that
were positive by RTPCR to confirm the results. Of 98 infertile patients, the prevalence of N. gonorrhoeae, C. trachomatis M.
genitalium and U. urealyticum were 8.1%, 10.2%, 7.1% and 46.9% respectively. Significantly, PID and BOH were associated
with infertility. Co-infections have been found in 1% to 5% among the organisms. Of 150 healthy women prevalence of M.
genitalium and U. urealyticum were 5.3% and 14% respectively. ECS was found to be sensitive specimen. Therefore RTPCR in
ECS could be helpful for diagnosis and screening in reproductive age group. These findings may be useful to guide therapy,
prevent transmission and infertility.
