Pubertal development in both boys and girls is characterized by the development of primary and secondary sex characteristics. Primary sex characteristics refer to the reproductive organs, such as the testes in boys and the ovaries in girls. During puberty, these organs begin to mature and become capable of producing sperm in boys and eggs in girls. In girls, the onset of menstruation, known as menarche, is a significant milestone in the development of primary sex characteristics. Secondary sex characteristics are physical changes that occur during puberty but are not directly related to reproduction. In boys, these changes include the growth of facial and body hair, deepening of the voice, and increased muscle mass. In girls, secondary sex characteristics include the development of breasts, widening of the hips, and the growth of pubic and underarm hair. Overall, pubertal development in both boys and girls is marked by the maturation of primary and secondary sex characteristics, as well as the onset of menarche in girls. These physical changes are a normal part of the transition from childhood to adulthood and are driven by hormonal changes in the body.
