ABSTRACT
We are herein putting forward the results derived from the careful examination of the ovary of a sexually mature Myocastor coypus which was carried out to establish a follicular typological series. Sexually mature virgin females from breeding farms were used and their ovaries were processed by routinely histological techniques. The following analysis criteria were considered for the follicular classification size of the oocyte in follicles at different stages of development, size of the follicle regarding the number of follicular cells, and follicular morphology. Complementary characteristics were also analyzed mean follicular diameter, presence and thickness of the pellucid zone, mean size of follicular cells, their shape in all follicular types, presence and extent of the antrum, and presence of thecas. By combining these different criteria, a follicular typological series was obtained according to Pedersen and Peters (1968) nomenclature together with a qualitative and quantitative characterization of the follicular types.
