Swaab and Fliers (1985) identified an area of the human hypothalamus that appears to be analogous to the sexually dimorphic nucleus of the rat medial preoptic area described by Gorski and colleagues.
For example, the medial preoptic area (MPOA) has been shown to be important for sexual arousal, copulatory behaviour, and the refractory period of male rats (Hoffman, Gerall, & Kalivas, 1987; Oomura, Aou, Koyama, Fujita, & Yoshimatsu, 1988).
