The sex difference in anxiety has long been a subject of extensive research in neuroscience and psychology. This paper aims to explore the underlying biological mechanisms that contribute to the observed sex-specific differences in anxiety-related behaviors. We review evidence from multiple fronts, including genetic, hormonal, neuroanatomical, and neurochemical factors. Genetic studies have suggested the involvement of sex-linked genes in anxiety-related traits, while hormonal factors, particularly gonadal hormones, have been shown to modulate anxiety-like behaviors in both sexes. Neuroanatomical differences in brain regions associated with anxiety, such as the amygdala and hippocampus, also contribute to the sex difference in anxiety. Finally, neurochemical factors, including neurotransmitters and neuromodulators, play a crucial role in the regulation of anxiety-related neural circuits. The current paper discusses these mechanisms in detail and highlights the importance of considering sex as a biological variable in anxiety research. Understanding the biological mechanisms underlying sex differences in anxiety can help us develop more targeted and effective treatment strategies for anxiety disorders.
