The physical and physiological attributes that set males apart from females within the human species are referred to as male sexual characteristics. Secondary sexual characteristics develop during puberty and throughout adulthood as a result of these traits, which are predominantly driven by the presence of male sex hormones, particularly testosterone. The growth of face and body hair is one of the most obvious male sexual traits. Increased testosterone levels throughout adolescence encourage the development of facial hair, which normally begins as a thin mustache and ultimately develops into a full beard. Males' body hair, such as their chest, back, and leg hair, also becomes more noticeable under the impact of testosterone. The extent of this hair growth, which is frequently viewed as a mark of masculinity, differs from person to person. A deeper voice is an important aspect of masculine sexuality. The larynx, or voice box, alters during adolescence as a result of rising testosterone levels. This results in the vocal cords lengthening and thickening, which lowers the voice's pitch. A man's voice can influence how attractive he is to potential partners because it is frequently linked to a man's sexual maturity. Male sex hormones also affect muscle mass and strength. Males have more muscle mass than females because testosterone encourages the growth of lean muscle tissue. The broader shoulders and more defined musculature that are frequently observed in men can be attributed to this increased muscle mass. It is also the cause of the increased physical strength that men normally display. In conclusion, male sexual features include a variety of physical and physiological qualities that set men apart from women. These traits, which include the development of facial and body hair, a deeper voice, greater muscle mass and strength, the Adam's apple, and the male reproductive system, are predominantly controlled by the presence of male sex hormones, particularly testosterone. These characteristics work together to give males in the human species their distinctive appearance and biological roles.
