Sperm morphological and morphometric evaluation in captive collared peccaries Pecari tajacu. Sousa; Erika A. Santos; Ana L.
Evaluate sperm morphology is an important parameter forsuccessful fertilization. In assisted reproduction techniques Kuster et al. Sanchezet al.
An important part of any breeding soundness exam is an evaluation of sperm morphology. In the most fundamental case, the size and shape of the head, midpiece and tail are examined. Additional information can be gained by evaluating integrity of the acrosome and sperm membranes. Sperm from different species vary in size and shape.

Sperm are considered to be normal if the shape and size of the head, midpiece and tail fall within the classification for a given species. It is important to select the appropriate technique for staining the semen of a given species, because, as many authors have pointed out, some methods work well for one species but are not suitable for analysing another.
