Absence of testes in Gorgoderina attenuata

, : Absence of testes in Gorgoderina attenuata. Journal of Parasitology 58(5): 1011-1012

Some specimens of Gorgoderina attenuata from frogs obtained from a commercial supplier in the USA lacked testes but contained normal eggs. Of 717 measured specimens, 193 with a mean length of 2.89 mm lacked testes while 524 with a mean length of 2.46 mm had testes. Ageing may affect testicular atrophy, particularly if development is protandric. The percentage of worms lacking testes was higher in winter and early spring.
