Testicular anomalies in the hybridogenetic frog Pelophylax esculentus (586 adults) and two parental species (193) were analyzed. The hybrids were characterized by an increased number of males with testicular anomalies (61%) compared to the parental species (17–20%). Diploid hybrids had more males with abnormal testes when compared to triploid hybrids. Among the hybrids with asymmetrical testes, males with a larger left testis were prevalent.
