title: [Questionnaire survey on sexual behavior of Japanese males infected with sexually transmitted diseases].
abstract: In Japan, there has been a rapid increase in recent years in the incidence of sexually transmitted diseases (STD), particularly in teenagers and people in their twenties. To determine the factors causing this increase in STD, we carried out a questionnaire survey on the sexual behavior of Japanese males. The subjects were 248 male patients who were treated at our outpatient clinic. The results of the survey showed that 1) about 70% of the male patients were infected through sexual intercourse with partners who were not paid for such services; 2) the average number of partners in the past year was 5.8, and the average number of partners was highest for the teenage group and decreased with age; 3) only 29 (12.4%) of the 234 males used condoms; and 4) 192 (82.0%) of the 234 males received oral sex. The results of the survey suggest that a large "sexual network" has been formed among young Japanese people and that a large percentage of young Japanese people are engaged in unprotected sex.
