It's not just my work in amphibians, but similar work has been shown in fish in Europe, holes in the testes and absence of sperm in reptiles in a group from South America and in rats, an absence of sperm in the testicular tubules as well.
Nije tako samo s mojim radom na vodozemcima, sličan je rad to pokazao i na ribama u Europi, rupe u testisima i odsutnost sperme kod gmazova u nekim grupama u Južnoj Americi i kod štakora, također izostanak sperme u testikularnim tubulima.
