The symptoms and signs were evaluated .The specimens from urethra and rectum were taken for gram stain, culture for Neisseria gonorrhoeae and ELISA (enzyme linked immunosorbent assay) test for Chlamydia trachomatis. The ulcer (if presented) were taken for detection of Treponema pallidum, Haemophilus ducreyi and Herpes simplex virus. The prevalence of anorectal sexually transmitted diseases was found in 13 cases (16.88%). Rectal chlamydia was detected in 7 cases (9.1%) and rectal gonorrhea was detected in 1 case (1.3%). Anal warts was detected in 5 cases (6.4%).Those with rectal chlamydia and gonorrhea were asymptomatic. Using the routine Gram' stain from specimen could not detect and diagnose both chlamydia and gonorrhea. Two cases of anal warts presented with anal lumps and two could identify that they had anal warts. One case of anal wart was asymptomatic.

In conclusion, the rate of anorectal sexually transmitted diseases in male patients who practice receptive anogenital sexual intercourse was not uncommon.
