摘　　要：目的探讨不同体成分青春前期男生体脂含量与性器官发育水平之间的关系。方法按照体脂比将研究对象分为肥胖、中等、消瘦3组,共筛选男生84名,追踪观察4年。采用Harpenden式卡钳检测皮褶厚度;采用放射免疫分析方法测定唾液睾酮水平。结果阴茎长径:消瘦组>中等组>肥胖组,且消瘦组、中等组男生阴茎长于肥胖组(P<0.05);从9岁开始,消瘦组、中等阴茎直径宽于肥胖组(P<0.05);男生睾丸4个发育指标(左长径、左横径、右长径、右横径)随年龄的增长而增长,且中等组和消瘦组要长于肥胖组;中等组和消瘦组男生的睾酮水平有高于肥胖组儿童的趋势;体脂比与性器官各指标呈负相关。结论肥胖与性器官发育不良可能有一定联系。Objective To study the relationship between body composition and the development of sexual organ among boys in prepuberty. Methods All boys were divided into three groups（obese, median, lean） according on the percent of body fat that was calculated based on the skin fold. Finally, 84 boys were filtered as objects and observed for four years. The measurement of skinfold thickness： Harpendenforceps. Radioimmunoassay（RIA） was used to determine testosterone. Results During the period of 4 years, the length of penis：lean group 〉 median group 〉 obese group, and there was significant difference of the length of penis between lean group, median group and obese group（P〈 0.05）. There was significant difference of the width of penis between lean group, median group and obese group（P〈 0.05） from age 9. With the age increasing, the length of testicles increased, and there was significant difference of the length of testicles between lean group, median group and obese group. There was negative relationship between sexual organ and % BF. Conclusion Obesity is associated with the maldevelopment of sex organs in prepuberty.
