长沙市7～17岁学生性征发育分段追踪调研报道

A Longitudinal Investigation of Sexual Character Development among Students Ages 7～17 in Changsha City

本文显示了长沙市7～17岁青少儿性征发育的动态规律，特别公布了其他性征调研报告中较少涉及的首遗和腋毛的发育水平数据，为将来进行大规模调查打下了一定基础。

This article describes the dynamic pattern of sexual character development of students aged 7～ 17 years in Changsha City and reveals the difference between the results of this dynamic observation and the static observation in the cities of our own and neighbouring provinces. Meanwhile, it provides information on initial spermatorrhoea and axillary hair development level for further research, which was reported very little in literatures.
