TL;DR: This research shows that the medial preoptic area‐anterior hypothalamus of the gerbil contains a sexually dimorphic area (SDA) whose morphology is influenced by adult gonadal steroids, and changes in the gross morphology of the mammalian brain after steroid hormone manipulations in adulthood are reported.

TL;DR: The data suggest that brain regions involved in male sex behavior are involved in different aspects of it and that this can also apply to different subsets of cells in each area, and that cells involved in mating do not necessarily show mating-related patterns of c-Fos expression.

TL;DR: The response of the developing hypothalamus to gonadal steroids may be asymmetric, and the effects of estrogen on gonadotropin secretion and reproductive behavior depended on both the region and the side of implantation.

TL;DR: Autoradiography was used to localize sex hormone‐accumulating cells in the gerbil brain and found that androgen uptake was more widespread than estrogen uptake in the brainstem, and androgen accumulation differed from the pattern of estrogen accumulation in one way.

TL;DR: The SDA is more important than other parts of the MPOA-AH in the control of mating and marking in male gerbils and its effects are less severe than similar lesions anterior or posterior to the SDA.
