The mice were captured from December 2003 to November 2004 in Fujinomiya, Shizuoka, Japan. In total, thirty-five matured male mice were studied. The mean value of testicular length was the high level from February to September. During these months the testicular length was more than 12mm. In contrast the mean testicular weight and plasma testosterone concentration peaked in April and August. The mean plasma testosterone concentration decreased to basal levels in June. The breeding season of the Large Japanese Field Mouse is considered to occur twice in the spring and autumn in the area under study. Despite the fact that the male Large Japanese Field Mouse was observed to be in a condition assumed to be morphologically agreeable to reproductive activity, it was clear that the mouse was not in an endocrinologically reproductive state. In addition, our data indicated that testicular weight correlated better with testosterone levels than did testicular length. We consider testicular weight could be a better indicator of reproductive activity than testicular length. Therefore, we considered that the falling season into side gutter was related to the breeding season activity.","subitem_description_type":"Other"}]},"item_1_description_13":{"attribute_name":"レポート・講演番号","attribute_value_mlt":[{"subitem_description":"E","subitem_description_type":"Other"}]},"item_1_description_15":{"attribute_name":"表示順","attribute_value_mlt":[{"subitem_description":"3","subitem_description_type":"Other"}]},"item_1_description_16":{"attribute_name":"アクセション番号","attribute_value_mlt":[{"subitem_description":"KJ00005353861","subitem_description_type":"Other"}]},"item_1_description_8":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_1_description_9":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_1_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00164184","subitem_source_identifier_type":"NCID"}]},"item_1_text_6":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"東京農業大学大学院農学研究科畜産学
