Purpose: To analyze the differences of semen parameters in Korean young population for three periods from 2002 to 2013.
Materials and Methods: A total of 516 semen samples were collected from Korean men presenting for infertility, varicoceles or other infectious problems for three periods from 2002 to 2012: January 2002-December 2003, January 2007-December 2008, and January 2012-December 2013. A standard World Health Organization procedure for semen analysis was performed for assessment of semen concentration, volume, motility, morphology, and pH.
Results: A total of 160, 162, 194 men constituted the study populations in 2002 to 2003, in 2007 to 2008, and in 2012 to 2013, respectively. The overall sperm parameter results suggested a statistically significant difference between 2002 to 2003 and 2012 to 2013 except pH. However, considering the data from 2007 to 2008, there were no trends in changes in overall semen parameters. Negative correlations were observed in all semen parameters with increasing age in all patients, except for pH. In addition, semen volume, motility, and morphology had higher negative correlation coefficients with age, from 2002 to 2013, serially.
Conclusions: There were no significant changes in the semen parameters of Korean men from 2002 to 2013. In addition, semen volume, motility, and morphology showed higher negative correlation coefficients with age from 2002 to 2013, serially.
