Abstract
The high prevalence of asymptomatic sexually transmitted infections in Japan have become a serious public health problem especially Chlamydia trachomatis infection in young women. On the other hand, it was reported that asymptomatic C. trachomatis infection was found in young healthy men at the rate of several percentage. To estimate the prevalence of asymptomatic sexually transmitted infections in young healthy men in Japan, we determine this study. Two hundred and four volunteers were recruited. The first voided urine specimens and cotton swab wiping of the external genitalia were used for detection of C. trachomatis, Neisseria gonorrhoeae and HPV. The participants asked to respond to a self-administered questionnaire for information about sexual behavior as the frequency of sexual intercourse, number of current sex partners. The prevalence were 3.4% for C. trachomatis and 5.9% for HPV. No N. gonorrhoeae was detected. In sexually active men who had regular sexual intercourse, the detection rate of C. trachomatis was 4.7% and that of HPV was 8.0%. The study showed that the prevalence of asymptomatic infections in young healthy men were not negligible.
