The aim of this sutdy was to analyse the spermogram of a group of captive African lions (Panthera leo), housed at the Fundação Parque Zoológico de São Paulo, as a subject to avaluate the reproductive potential of the animals, an important aspect to apply artificial reproductive techniques. After chemical restraining, semen from 14 adult male lions was obtained by electroejaculation and the samples were examined right after the collection. The characteristics analyzed were: volume, pH, general aspect, motility, progressive motility, spermatic motility index and concentration. One aliquot of the samples were fixed in saline-formol solution 10% and examined under Phase Contrast Microscopy for morphological evaluation, classifying in minor and ...
