摘要
目的：比较分析我国近10年男性首次遗精年龄的基本状态、变化规律和特点。方法：采用文献分析的方法，收集分析了1995-2005年发表的学术文献56篇，均来源于全国60个地区，共累计50余万人的数据。结果：1995-2005年我国男性首次遗精年龄呈明显的逐渐提前的趋势（Y=-0.1507x＋315.79，P〈0.0001）；首次遗精平均年龄南方（14.36±0.58岁）比北方（14.67±0.91岁）提前0.31岁，未见统计学差异（P〉0.05）；沿海地区为14.22±0.70岁，内地为14.56±0.57岁，西部地区为14.82±1.06岁，沿海比西部地区明显提前0.60岁（P〈0.05）；同一地区的城市（14.18±0.57岁）比农村（14.68±0.60岁）明显提前0.50岁（P〈0.0001）；发达地区（14.28±0.55岁）比欠发达地区（14.95±0.87岁）明显提高0.67岁（P〈0.01）；相同地区的不同民族表现有所不同，汉族除晚于蒙古族外，均提前于回族、黎族、藏族；肥胖青少年早于正常青少年2.16岁。结论：男性首次遗精年龄受经济、文化、社会环境等诸多因素综合的影响，呈现普谝提前的趋势。
Objective： To analyze the variation trend and characteristics of the age of the first spermatorrhea of Chinese adolescence in the past ten years. Methods： Fifty - six academic literatures published between 1995 and 2005 were analyzed. The data were collected from 60 areas in China and involved in more than 500 thousand men. Results ： Between 1995 and 2005, the age of the first spermatorrhea in Chinese adolescence showed a tendency to be advanced gradually （y=-0.1507x ＋ 315.79, P 〈 0.01 ）. The average ages of the first spermatorrhea in adoleseenees living in the south and north China were 14.36±0.58 and 14.67±0.91 years old respectively, with a difference of 0.31 years old （ P 〉 0.05 ）. They were 14.22±0.70, 14.56±0.57 and 14.82±1.06 years old in the coastal, inland and western regions of China respectively. It showed a significant difference of 0.60 years old between the coastal and western regions （ P 〈 0.05 ）. Moreover, they were 14.18±0.57 and 14.68±0.60 years old in the urban and rural areas of the same study sites respectively, showing a significant difference of 0.50 years old （ P 〈 0.01 ）. And they were 14.28±0.55 and 14.95±0.87 years old in developed and less developed areas respectively, with a significant difference of 0.67 years old （P 〈0.01）. In addition, it was inconsistent in the characteristics of age among different nationalities. Adolescences of Han nationality were younger than those of the Hui, Li and Tibetan nationalities and elder than Mongolian adolescenees when they experienced the first spermatorrhea. And the first sperma-torrhca in the obese adolescences occurred 2.16 years in advance. Conclusion： The age of the first sperma-torrhea in Chinese adolescence may be influenced by multiple factors, such as economics, culture and social environment. The first spermatorrhea in Chinese adolescence has tended to occur in advance.
