This is triggered by the pituitary gland, which secretes a surge of hormonal agents into the blood stream, initiating a chain reaction to occur.The male and female gonads are subsequently activated, which puts them into a state of rapid growth and development; the triggered gonads now commence the mass production of the necessary chemicals.The testes primarily release testosterone, and the ovaries predominantly dispense estrogen.The production of these hormones increases gradually until sexual maturation is met.Physical growth (particularly in males), and cognitive development can extend into the early twenties.Thus age provides only a rough marker of adolescence, and scholars have found it difficult to agree upon a precise definition of adolescence.Puberty occurs through a long process and begins with a surge in hormone production, which in turn causes a number of physical changes.

Furthermore, even within a single nation state or culture there can be different ages at which an individual is considered (chronologically and legally) mature enough for society to entrust them with certain privileges and responsibilities.

Males experience their growth spurt about two years later, on average, than females.

During their peak height velocity (the time of most rapid growth), adolescents grow at a growth rate nearly identical to that of a toddler—about 4 inches (10.3 cm) a year for males and 3.5 inches (9 cm) for females.

In addition to changes in height, adolescents also experience a significant increase in weight (Marshall, 1978).

The weight gained during adolescence constitutes nearly half of one's adult body weight.
