摘要
1986年4月至12月对北京市一所普通中学289名12～16岁的男生进行了性发育研究,初步了解了男生的性发育状况,探讨了睾丸、阴茎的检查方法及性发育状况的综合表示方法,并研究了性发育和形态发育的关系,发现13、14岁男生随着性发育程度的提高,形态发育水平也提高,而形态发育速度则逐渐减慢,提示性发育和形态发育间存在着密切联系。
A sexual development study was taken on 289 boys of age 12—16 from April 1986 to December 1986. The changes of reproductive organs and secondary sex characters were observed. We investigated how to measure the testes and penis, and how to indicate the level of sexual development in a synthetic way. The relationship between sexual and morphological development was studied. As the level of sexual development is elevated, the body measurements increase and the height and weight velocities decrease gradually. It is showed that the sexual and morphological development are closely associated.
