Summary The medial preoptic nucleus of the porcine hypothalamus is characterized by an age‐dependent sexual dimorphism in the postnatal period of the development. It manifests itself as sexual differences in the density and volume of the perikarya. A transient concentration of perikarya in the centre of the medial preoptic nucleus, especially distinctive in male piglets, is somewhat similar to the ‘sexually dimorphic nucleus of the preoptic area’ of Gorski, as characterized in rats.
