Zusammenfassung:	Research highlights ► Sheep (ovine) model of exclusive same-sex sexual partner preference. ► Anatomical correlates of sexual partner preferences. ► Identification of an ovine sexually dimorphic nucleus (oSDN) in the medial preoptic area. ► Evidence that the size of the oSDN is organized prenatally by testosterone.
