This article determines the influence of the animal’s age on the morphometric parameters of spermatozoa in sperm obtained from male rabbits. For this purpose, three groups were formed: the first group at one year of age; the second group is from 2 to 3 years of age; the third group is over 3 years old. From each group of rabbits, 5 smears were prepared and morphometric parameters of spermatozoa were determined, such as: head length; head width; neck-tail length; length of the entire body in micrometers (µm)
