Additional file 2:

Mean values and range of corporal and sperm dimensions in 226 species of eutherian mammals. CV is the coefficient of variation. % TSL is the mean percentage of the total sperm length represented by each sperm component. The mean percentage of increment indicates the difference between the lowest to the highest value among species.

Relations between testes mass (g) and body mass (g) in 226 species of eutherian mammals. Values have been converted to Log10 (p < 0.0001, R2 = 0.85). The line represented corresponds to the equation of the relation between these two variables published by Kenagy & Trombulak (1986): Log testes mass = (0.72 * Log10 body mass) - 1.4559.
