Question

Place the events that occur during puberty in males in chronological order, from the earliest event to the latest.

Answer 1

Puberty in males follows a specific sequence of physical changes, starting with the growth of the testes and scrotum, followed by the growth of the male organ and the development of pubic hair and other secondary sex characteristics. The voice also deepens during this time. The first fertile ejaculations usually occur around age 15, and the male growth spurt occurs between ages 11 and 13.

Step-by-step explanation:

1. In boys, puberty begins when the pituitary gland tells the testes to secrete testosterone.
2. The growth of the testes is typically the first physical sign of the beginning of puberty, followed by growth and pigmentation of the scrotum and growth of the male organ.
3. Next, hair growth occurs, including armpit, pubic, chest, and facial hair, and testosterone stimulates the growth of the larynx and thickening of the vocal folds, causing the voice to drop in pitch.
4. Finally, the first fertile ejaculations typically appear around the age of 15, and the male growth spurt occurs between ages 11 and 13, with a potential increase in height of up to 4 inches a year. Some males may continue to develop throughout their early 20s.
