[Abstract]:Objective to analyze the basic status, changes and characteristics of the age of first spermatogenesis in Chinese adolescents. Methods by means of meta-analysis (meta analysis), computer and manual literature retrieval, data screening, processing and quality evaluation were carried out according to the criteria of acceptance, and 192 data were obtained from 74 published academic literature reports from 1980 to 2013. Nearly 435000 people were involved. Results from 1980 to 2013, the age of first spermatogenesis was significantly earlier (y = 0.0424 x 99.129, R = 0.3268, P0.01). The mean age of first spermatogenesis was 14.40 years old, from 15.18 years old in 1980 to 13.78 years old in 2013, the age of first spermatogenesis was 14.40 years old, and the age of first spermatogenesis was 13.78 years old in 2013, from 15.18 in 1980 to 13.78 years in 2013. Change of 1.40 years in 34 years; There was a significant negative correlation between the age and the southern and northern regions (P0.0001), which was 1.16 and 1.33 years earlier in 34 years, respectively. The age of the first spermatogenesis in the northern region was obviously later than that in the south (P0.001), but it was faster with the age than that in the south. The urban area in the same area was significantly earlier than that in the rural area (P0.001), but the range of advance (1.39 years old) in the rural area was higher than that in the urban area (0.91 years old), and the difference between the urban and rural areas was decreasing. There are obvious interactions between urban and rural factors in the three decades (1980-1995, 1996-2005 and 2006-2013) and regions (South and North) (P0.001). Conclusion from 1980 to 2013, the age of first spermatogenesis of adolescents in China was significantly earlier. The age, regional, urban and rural differences and the interaction between urban and rural areas would have an impact on the age of first spermatogenesis.
