目的探讨首次遗精与骨龄发育之间的关系。方法追踪调查法。结果首次遗精平均时间年龄为13．52岁，平均骨龄为14．91岁。种籽骨可在首次遗精后出现，与身高突增高峰基本同步，早遗与中、晚遗相比，其形态指标盆宽／肩宽有统计学差异。结论首次遗精的早晚对以后身体充实程度、心肺发育、体力均无明显影响，种籽骨的出现标志着全面的生长发育突增高峰的到来。
Objective To explore the relationship between the first spermatorrhea and bone age development. Methodology Results The mean time of first spermatorrhea was 13.52 years and the average bone age was 14.91 years. Seeds bones can appear after the first spermatogenesis, which is basically synchronous with the peak height of sudden increase. Compared with the middle and late remains, the shape indexes of the early sequelae are statistically different. Conclusion The first spermatorrhea had no effect on physical enrichment, cardiopulmonary development and physical strength in the future, and the appearance of seeding bones marked the arrival of a sudden peak in growth and development.
