Macho mice make manly melodies.
Susan Reardon points to work by work of Pasch et al at U of F at Gainesville, who compared the songs of castrated male mice (singing mice from Costa Rica) with males having a male hormone implant. Females were attracted to speakers playing recordings of the songs of hormonally encanced males. (audio file here, video file in links above).
