Fathers and sons, mothers and daughters: Sex-specific genetic architecture for fetal testosterone in a wild mammal
Horm Behav. 2024 Mar 6;161:105525. doi: 10.1016/j.yhbeh.2024.105525. Online ahead of print.ABSTRACTTestosterone plays a critical role in mediating fitness-related traits in many species. Although it is highly responsive to environmental and social conditions, evidence from several species show a heritable component to its individual variation. Despite the known effects that in utero testosterone exposure have on adult fitness, the heritable component of individual testosterone variation in fetuses is mostly unexplored. Furthermore, testosterone has sex-differential effects on fetal development, i.e., a specific level may b...

Social regulation of arginine vasopressin and oxytocin systems in a wild group-living fish
Horm Behav. 2024 Mar 6;161:105521. doi: 10.1016/j.yhbeh.2024.105521. Online ahead of print.ABSTRACTThe neuropeptides arginine vasopressin (AVP) and oxytocin (OXT) are key regulators of social behaviour across vertebrates. However, much of our understanding of how these neuropeptide systems interact with social behaviour is centred around laboratory studies which fail to capture the social and physiological challenges of living in the wild. To evaluate relationships between these neuropeptide systems and social behaviour in the wild, we studied social groups of the cichlid fish Neolamprologus pulcher in Lake Tanganyika, Afr...

Estrogenic influences on agonistic behavior in teleost fishes
Horm Behav. 2024 Mar 5;161:105519. doi: 10.1016/j.yhbeh.2024.105519. Online ahead of print.ABSTRACTTeleost fishes show an extraordinary diversity of sexual patterns, social structures, and sociosexual behaviors. Sex steroid hormones are key modulators of social behaviors in teleosts as in other vertebrates and act on sex steroid receptor-containing brain nuclei that form the evolutionarily conserved vertebrate social behavior network (SBN). Fishes also display important differences relative to tetrapod vertebrates that make them particularly well-suited to study the physiological mechanisms modulating social behavior. Spec...

The role of exogenous testosterone and social environment on the expression of sociosexuality and status-seeking behaviors in young Chilean men
Horm Behav. 2024 Mar 5;161:105522. doi: 10.1016/j.yhbeh.2024.105522. Online ahead of print.ABSTRACTTestosterone plays an important role as a social hormone. Current evidence suggests that testosterone is positively related to sociosexuality increasing the psychological attitudes toward investing in short-term versus long-term mating and promotes status-seeking behaviors both by dominance and prestige. In addition, the social environment may play an important role in the expression of mating effort through changes in sociosexuality and status-seeking behaviors. However, the causal relationships among the mentioned variables...

Low dose of propyl-pyrazole-triol, an agonist of estrogen receptor alpha, administration stimulates the Coolidge effect in fadrozole-treated male rats
Horm Behav. 2024 Mar 5;161:105520. doi: 10.1016/j.yhbeh.2024.105520. Online ahead of print.ABSTRACTEstrogen receptor (ER) α is involved in male sexual function. Here, we aim to investigate how ERα activation influences sexual satiety and the Coolidge effect (i.e., when a rat, that has reached sexual satiety, experiences an increased arousal after exposure to a novel sexual partner) in estrogen-deprived male rats. Male rats (8 per group) were treated daily for 29 days with either saline (Control group) or fadrozole dissolved in saline (1 mg/kg/day) 1 h before mating. On Days 13 and 29, rats treated with fadrozole received...
