- Abstract
Testes asymmetry theory predicts that males in good condition or mature age may be able to develop larger degrees of directional asymmetry than males in poor condition or young age. We tested the testes mass and testes asymmetry hypothesis in the Chinese endemic frog (Rana omeimontis). The results showed that R. omeimontis had a significantly directional testes asymmetry, with left testis being significantly larger than right testis. Male body condition was negatively correlated with relative testes mass, but not correlated with testes asymmetry. However, male age was correlated with testes mass and asymmetry, suggesting males with larger testes and a higher degree of testis asymmetry survive better.
