Abstract:
The study of the reproductive activity of species is of fundamental importance for
understand the processes that organisms go through and adapt. The present work
searched through a bibliographic survey. compare and analyze the similarities or
differences among other representatives of amphibians, with emphasis on the histological relationship
testicular during the spermatagenesis process. Through identification and description
of the different cells found in the testes of Leptodactylus macrosternum.
Forty-one specimens of the species were collected at Fazenda do Cajueiro. municipality of Catolé do
Rocha/PB, from October 2013 to June 2014, through intensive
auditory-visual searches in the trained areas. Then. the specimens were taken to the
Amphibian Biosystems Laboratory (LABAN) - UFCG/CES where the specimens
they were euthanized, photographed and identified. and afterwards. removed the gonads and
performed histological cottes for mounting the slides. Germline cells
were organized in cysts, within the seminiferous epithelium, with the presence of all
the cells organized in different stages of differentiation, characterizing in a
cystic spermatogenesis, a common feature in all amphibians. L. macrosternum, like this
like the other species analyzed in this study, it presented histological characteristics
identical testicular. Among the aspects studied, the only relevant difference was observed
in the coloration of the gonads.
