Studies reporting the sperm count as well as the sperm morphology and quality of Turkish men are limited with case reports and they do not build up a general consensus on this matter. Because of this reason, we evaluated any possible changes in semen quality parameters of Turkish normospermic men during the past 16 years. This is a retrospective study of 24693 men with semen data between 1995 and 2011. Semen quality was evaluated by individual and age dependent (age groups: 18-25, 26-30, 31-35, 36-40, 41-50) statistical analysis of semen volume, sperm concentration, total sperm count and motility. Considering all age groups, mean sperm concentration was found to be 73.2x106/mL. We also demonstrated that mean semen volume of Turkish men is 3.93 ±1.93 mL. C (+2) motility parameter significantly decreased in all age groups. Considering the high number of cases included and the duration studied, the present study is first in reporting Turkish men semen quality.
