Summary: Through studying Syrian hamsters, it was found that social experiences can alter individual responses to stress, winning aggressive encounters can increase testosterone levels and affect the neural network, and establishing social dominance can lead to changes in neuroendocrine mechanisms.

Summary: Living in a group can bring benefits to individuals, but also exposes them to intense competition. Individual behavior can directly and indirectly influence the behavior of others, as well as affect group characteristics. Dominant males in stable communities have higher testosterone levels compared to subordinate males.

Summary: Aggression is a fundamental behavior in animal species, but excessive or insufficient aggression can have negative consequences for individuals and group members. Research has shown the importance of nuclear steroid hormone receptors in regulating aggressive behaviors in male zebrafish.

Summary: This study evaluated the frequency and type of androgen receptor (AR) gene variants in a large cohort of infertile males. The study found that patients with AR gene variants had lower sperm count, higher testosterone concentration, and higher androgen sensitivity index compared to patients without variants. Two novel potentially pathogenic AR variants were identified. Based on these findings, AR sequencing is suggested as a routine genetic test in cases of idiopathic oligozoospermia with high testosterone levels.

Summary: When being watched, humans behave more prosocially, and the hormone testosterone can diminish feigned prosociality and decrease submission to audience expectations. Testosterone does not impair reinforcement learning, but alters the translation of choice value information into action selection when being observed. This study provides novel evidence of testosterone's effects on implicit reward processing, counteracting conformity and deceptive reputation strategies.

Summary: This article discusses the central role of human activities in sustainability and explores the idea of radically reducing human activities to address issues like climate change. The authors argue that social mechanisms accelerate rather than slow down activities, making them largely unavailable for sustainability measures. They propose recognizing and utilizing social mechanisms in technology assessment and sustainable development research to achieve transformative impact on systemic reproduction.

Summary: Elevated testosterone in male dark-eyed juncos leads to increased telomere shortening with age, potentially affecting longevity. This suggests that the impact of testosterone on telomeres may be a long-term cost of reproduction in male vertebrates.

Summary: Although testosterone replacement therapy is commonly used for men with classical hypogonadism, its role in age-related decline of testosterone remains unclear due to limited evidence from long-term clinical trials. However, men aged 50 years and above with comorbidities and higher body mass index often exhibit symptoms of androgen deficiency and low testosterone levels. Clinicians face a challenging dilemma in initiating testosterone therapy and must carefully assess the benefits and risks based on limited clinical trial data. In this article, a practical approach to the assessment and management of such men is presented using a case scenario.

Summary: This study found that dominant individuals in non-human primate species who were more tolerant tend to vocalize at a higher rate, while despotic species have a larger repertoire of hierarchy-related vocalizations. This suggests that primate signals evolve in relation to the nature of interactions that characterize individuals' social relationships.

Summary: This study revealed the relative importance of male and female identity in male courtship behavior, as well as the increased male responsiveness to stimulus females as the breeding season progressed. Furthermore, the results suggest that invitation latency is a consistent courtship attribute in males that can be adjusted plastically according to perceived female quality and environmental conditions.

Summary: This study assessed male Astatotilapia burtoni fish in cognitive tasks before and after a community perturbation. The researchers found that ascending males underwent physiological changes and showed preference for novel object recognition during the perturbation, and differed in social competence from non-ascenders. Principal component analysis also identified specific cognitive and physiological attributes that predispose certain individuals to ascend in social status.

Summary: Although research on the avian hippocampus has been limited, it is crucial for understanding its evolution and changes over time. The avian hippocampus plays important roles in spatial cognition as well as regulating anxiety, approach-avoidance behavior, and stress responses. Future research should focus on elucidating the cellular and molecular mechanisms, including endocrinology, to resolve outstanding questions about avian hippocampal function and organization.

Summary: This study investigates the effects of urbanization on hormone levels in tungara frogs and found that urban frogs and forest frogs have different endocrine phenotypes. Exposure to urban noise and light pollution led to an increase in testosterone and a decrease in corticosterone in urban frogs, while forest frogs showed no endocrine response to sensory pollutants. These results suggest that urbanization can modulate hormone levels and influence behavior in frogs.

Summary: Social hierarchies have significant effects on overall health of individuals in animal groups, particularly the lowest-ranking individuals. Tube test can be used to determine social rank in male and female mice, and the complex interactions between social rank, sex, environment, and testing length influence peptide levels.
