Abstract

Sexual behavior was evaluated in 2228 Japanese males aged from 42 to 94 years of age. They were interviewed individually by well-trained urologists, when mass screening for prostatic diseases was performed. Concerning the first sexual intercourse early could be distinguished by the same characteristics. The age of impotence in office workers and daily smokers was significantly young. Compared with American males in the literature, the characteristic features of sexual behavior in Japanese males were as follows; 1) The age of first sexual intercourse was more than 7 years after that of American males, 2) The frequency of sexual intercourse before 40 years of age was higher, but that after 40 years of age was less, than that of American males, 3) The age at which sexual intercourse was no longer practiced was almost the same in the two countries.
