Adolescence is a transitional stage between childhood and adulthood marked by rapid physiological changes due to hormonal activity. These changes occur as a result of the activation of the endocrine system, particularly the pituitary gland, which stimulates the gonads to produce sex hormones. In the context of family education, understanding these changes helps parents and caregivers guide adolescents with sensitivity, awareness, and proper support. In males, adolescence generally begins between the ages of 10 and 14 years. One of the earliest signs is an increase in the size of the testes and scrotum, followed by enlargement of the penis. The testes begin to produce sperm, marking the onset of reproductive capability. This stage is often accompanied by nocturnal emissions, commonly known as “wet dreams,” which are a normal physiological process indicating sexual maturity. Family education plays an important role in preparing boys for these changes and removing misconceptions or fear related to them.

The shoulders broaden, and the body becomes more muscular under the influence of testosterone. Along with skeletal growth, the voice box or larynx enlarges, causing the voice to crack and gradually deepen. This change may initially cause embarrassment,
