Although the effect of maternal age on fertility is well known, it is unclear whether paternal age also affects fertility. The aim of this retrospective study was to establish an association between the age of the individuals from Medellin, Colombia with semen volume, rapid progressive motility (a), total progressive motility (a + b) and concentration.

Semen volume, rapid progressive motility (a) and total progressive motility (a+þ), concentration and total sperm count were inversely related to age. A gradual, consistent and significant decline in sperm parameters was observed over time.

This study indicates that a significant decline in volume, rapid and total progressive motility, and sperm count exists among older men compared with younger men. To our knowledge, this is one of the largest reports analyzing the effect of male age on sperm parameters in three age groups without differences in the duration of sexual abstinence. Therefore, in the present study sexual abstinence can be excluded as variable bias.
