Masculinity (also called manhood or manliness) is a set of attributes, behaviors, and roles associated with men and boys. Masculinity can be theoretically understood as socially constructed,[1] and there is also evidence that some behaviors considered masculine are influenced by both cultural factors and biological factors.[1][2][3][4] To what extent masculinity is biologically or socially influenced is subject to debate.[2][3][4] It is distinct from the definition of the biological male sex,[5][6] as anyone can exhibit masculine traits.[7] Standards of masculinity vary across different cultures and historical periods. It is traditionally contrasted with femininity.
