The current andrological exams evaluate the concentration, vigor, motility, swirling and morphological pathologies of spermatozoa. However, even when approved for andrological examinations, some bulls do not respond effectively, either in natural mating or in vitro fertilization processes. Alterations in the sperm chromatin can be a factor that influence the performance of bulls and is usually not evaluate in andrological exams. This study aims to evaluate the condensation of chromatin during sperm maturation in the epididymis, correlating morphometric characteristics of spermatozoa, chromatin condensation and epididymal maturation. For this, spermatozoa were collected from the seminiferous tubule, head, body and tail of the epididymis, as ...
