"MAN" typically refers to an adult human male, distinguished from a boy, who is a male child. Men are characterized by biological traits such as higher levels of testosterone and the presence of XY chromosomes. They often take on various roles in society, including family, work, and community responsibilities. In many cultures, the concept of masculinity is associated with traits like strength, leadership, and assertiveness. However, societal expectations of men can vary widely across different cultures and time periods. The study of gender roles often includes discussions about masculinity, feminism, and gender equality.
