Sexual differentiation of the central nervous system
TL;DR: In many higher vertebrates, an integral part of this process is the induction of permanent and essentially irreversible sex differences in central nervous function, in response to gonadal hormones secreted early in development.

Gonadal hormones and sex differences in nonreproductive behaviors in rodents: Organizational and activational influences
TL;DR: Sexual dimorphic responses in the rat are often not similarly differentiated in the hamster, the gerbil, or the mouse; and major differences exist among rodent species in hormonal effects on such responses, suggesting whether sex differences in certain laboratory learning tasks have any adaptive significance.

Androgens and the evolution of male-gender identity among male pseudohermaphrodites with 5alpha-reductase deficiency.
TL;DR: To determine the contribution of androgens to the formation of male-gender identity, male pseudohermaphrodites who had decreased dihydrotestosterone production due to 5α-reducta...

Rodent sex differences in emotional and related behavior.
TL;DR: Rodent sex differences in the following tests are reviewed: the open field, emergence from the home cage, active and passive avoidance learning, reaction to shock, and heart rate responses to novelty.

Differentiation of coital behavior in mammals: A comparative analysis
TL;DR: Testicular androgen may cause behavioral defeminization only in those species in which expression of feminine sexual behavior normally depends on the neural action of progesterone, acting synergistically with estradiol; new data support this claim in the ferret.
