Adolescence & Puberty

Adolescence: is the passage from childhood to adulthood.
Puberty: changes that lead to reproductive capacity.
Girls:
the 1st visible sign of puberty and the hallmark of SMR2 is the appearance of breast buds, between 8 and 12 yr of age. Menses typically begins 2-2.5yr later, during SMR3-4. Peak height velocity occurs early (at breast stage II–III, typically) in girls and always precedes menarche.
Completion of the Tanner stages (5 stages) should take approximately 4 to 5 years.
Boys:
1st visible sign of puberty and the hallmark of SMR2 is testicular enlargement, beginning as early as 9.5 yr. This is followed by penile growth during SMR3. Peak growth occurs when testis volumes reach approximately 9-10 cm3 during SMR4. The growth spurt is a relatively late event; it can occur from 10.5 years old to 16 years old.
Deepening of the voice, facial hair, and acne indicate the early stages of puberty.
