Sperm Morphology and Motility in Different Age Populations

Abstract

A prospective study of 77 semen specimens was conducted by routine examination of patients reporting to our laboratory for sterility problems. Abnormal spermatozoa were found mostly in patients over 40 years of age. The most frequent head abnormality was angulation of head (found in 94% of patients) and the most frequent tail abnormality was bent tail (found in 90% of patients). Immature spermatozoa were noted mostly in patients over 40 years of age. Motile sperm concentration was higher in patients up to 26 years of age. However, there was a remarkable heterogeneity of routine andrological parameters within the examined groups.
