Why Do Male House Mice Have Such Small Testes?
Original language description
We studied testes size in free-living and laboratory-born commensal and non-commensal populations of various Mus species (M. musculus musculus, M. m. domesticus, M. spicilegus, M. spretus, M. macedonicus, and laboratory mice). All thirteen samples representing various populations of Mus musculus exhibited smaller testes (0.7-1.0%), and the three lowest mean values came from laboratory mice (0.5-0.7%). It is very surprising that aboriginal species, in particular M. spicilegus, which is widely consideredto be monogamous, have relatively larger testes than the polygynous/promiscuous M. musculus. This result is in apparent contradiction to the current views on evolutionary forces affecting testes size, and suggests that there could be another uncontrolledfactor obscuring the relationship between testes size and multiple paternity.
