We described the morphohistological features of the testis of adult Odontophrynus americanus (Dumeril & Bibron 1841) (n = 7) from wetlands of central Argentina. Testes were processed by routine histological techniques, sectioned at 8 microns and stained with hematoxylin.eosin. The gonads are paired, yellowish and ovoid organs, 5.25 �} 0.17 mm long x 2.15 �} 0.15 mm wide. Histologically, there is a thin tunica albuginea (4.90 �} 1.05 m�Ê) surrounding the testicles. Inside them, there are seminiferous locules measuring 280.47 �} 59.73 m�Ê in diameter, distinguished in cysts with spermatogenic cells at different stages of development. The interstitial tissue is scarce and the Leydig cells and blood vessels stand out. Spermatogonia I are the la...
