Objectives: To determine the relationship between the quality of human semen and age. Methods: A spermatogram was performed following the WHO´s laboratory manual to evaluate human sperm and the interaction between cervical mucus and semen (1999) from July 2003 and December 2008. We studied 2441 male cases that fulfilled the inclusion criteria. Results: A+B motility was 51.55% for 20-29 years of age male participants; normal spermatozoids were found in 77.73% of males above 50 years of age; the spermatic count (mill/ml) was 61.09 for males above 50 years of age. Spermatic motility had a multiple lineal correlation coefficient of 0.222 and a determination coefficient of 0.049; respective values for the spermatic count were 0.465 and 0.216. Conclusions: There is an inverse trend between motility and age, a direct trend between spermatic count and age, and a constant trend between spermatic morphology and age.
