Description
Abstract
Following previous studies about the
ultrastructure of male genital tract in parental species, a
comparative study of epididymis of one of the possible
hybrids, the mule, has been undertaken.
Apart from small differences, general features of
epididymal epithelium in the mule are similar to those of
parental species. However, extension of our studies from
the donkey to the horse to the hybrid permits a deeper
insight into the morphology of this tract of excurrent
duct. In the meantime, it is possible to evidence some
features, sometimes shared with other species if taken
separately, which in the whole characterize the
epididymis in Equidae: the presence in principal cells of
intranuclear inclusions and peculiar small granules in the
basa1 cytoplasmic edge; the organization of groups of
cells, likely to be principal ones, in such a way as to
constitute intraepithelial crypts; a cumbersome presence
of lipofuscinic matter al1 along the epithelium. Another
interesting observation is the presence in the mule
epididymis of well recognizable macrophages. Al1 these data are discussed in comparison with
parental species and with other species described in
literature. Beyond any other consideration, it can be
outlined that the complex morphology of the epithelium
lining ductus epididymis in the mule is unaffected by
the absence of spermatozoa, which are normally the
target of the manifold functions of the epithelium itself.
