Male Secondary Sexual Characteristics

Meaning

Male Secondary Sexual Characteristics are the physical traits that distinguish adult males from females but are not directly involved in reproduction. These features develop primarily during puberty under the influence of androgens and serve as visual and physiological markers of sexual maturity and hormonal status. Key characteristics include increased muscle mass, a deeper voice due to laryngeal enlargement, the development of facial and body hair, and specific changes in skeletal structure, such as a broader shoulder girdle and a more prominent jawline. These characteristics are central to sexual dimorphism in humans.
