Maternal contributions to the development of masculine sexual behavior in laboratory rats.
TLDR
It was concluded that stimulation from maternal licking contributes toward the development of a mechanism that underlies the timing of copulatory rate.Abstract:
Maternal licking was manipulated by lining the nasal passages of rat dams with polyethylene tubing to interfere with their olfactory competence. Olfactory cues from pups elicit maternal licking and handling, particularly of anogenital regions, and dams with olfactory deficits were observed to lick their pups less. Mature male and female offspring of these dams and their controls were gonadectomized, treated with testosterone propionate, and tested for masculine sexual behavior. The male offspring of dams that provided less maternal licking had longer ejaculatory latencies, longer post-ejaculatory intromission latencies, and longer inter-intromission intervals than controls. Female offspring of the intubed dams performed fewer mounts and intromissions, had longer intromission latencies, and longer inter-intromission intervals. It was concluded that stimulation from maternal licking contributes toward the development of a mechanism that underlies the timing of copulatory rate.read more

TL;DR: It is suggested that maternal behavior serves to "program" hypothalamic-pituitary-adrenal responses to stress in the offspring.

Reframing sexual differentiation of the brain
TL;DR: A more appropriate model is a parallel-interactive model that encompasses the roles of multiple molecular signals and pathways that differentiate males and females, including synergistic and compensatory interactions among pathways and an important role for the environment.

Prenatal stress and risk for psychopathology: specific effects or induction of general susceptibility?
TL;DR: The evidence supports the view that exposure to prenatal stress may result in a general susceptibility to psychopathology, rather than exerting a direct effect on a specific form of psychopathology.

Linking prenatal maternal adversity to developmental outcomes in infants: The role of epigenetic pathways
TL;DR: Evidence illustrating the association between maternal prenatal distress and both fetal and infant developmental trajectories and the potential role of epigenetic mechanisms in mediating these effects are discussed.

Male Sexual Behavior
TL;DR: Major areas controlling sexual motivation and performance in males include the mesolimbic dopamine (DA) system, the medial preoptic area (MPOA), the amygdala, and the bed nucleus of the stria terminalis (BST).

TL;DR: Lactating Long-Evans rats were observed to interact differently with male and female pups during the first 18 days postpartum, with major differences in the mother's behavior related to the gender composition of her litter and to the sex of individual pups within her litter.

TL;DR: New-born male and female rats possess an undifferentiated mechanism for regulating the release of gonadotrophins, which becomes differentiated in immature males into an acyclic mechanism by the action of the male hormone secreted by the testis and in immature female rats this mechanism remains cyclic in type.

TL;DR: The onset of maternal responsiveness by virgin female rats to foster pups was observed after (i) complete vomeronasal nerve cuts, (ii) partial olfactory bulb cuts, or (iii) the combined procedures.

Functional Analysis of Masculine Copulatory Behavior in the Rat
TL;DR: The primary concern in this chapter is to describe how the elements of copulatory behavior are wired together, rather than how the nervous system controlling that behavior is wired together.
