The compensation hypothesis predicts that if the left testis is defective e.g. due to developmental stress, the increased right testis serves a compensatory role, and thereby displaying testes asymmetry which can be a reliable indicator of male body condition. Here, to test the prediction of the compensation hypothesis, we analyzed difference in size between left testis and right testis and the relationship between testes asymmetry and male body condition in the swelled vent frog (Feirana quadranus). We found that the left testis was larger than right testis, displaying a significant directional asymmetry in testes size. Although testes mass was correlated with body condition, testes asymmetry was not correlated with body condition, which cannot provide evidence that the right testis had a compensatory function. Our findings suggest no evidence for the compensation hypothesis in this species due to lacking the compensatory function in right testis.
