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.
对2228名年龄在42岁至94岁之间的日本男性的性行为进行了评估。在进行前列腺疾病大规模筛查时，由训练有素的泌尿科医生对他们进行单独访谈。关于首次性行为较早的情况可以通过相同特征加以区分。上班族和经常吸烟的男性出现阳痿的年龄明显较小。与文献中美国男性相比，日本男性性行为的特征如下：1）首次性行为的年龄比美国男性晚7年多；2）40岁之前性行为的频率高于美国男性，但40岁之后则低于美国男性；3）两国不再进行性行为的年龄几乎相同。
