Question 3

Question 4

What is precocious (early) puberty?

Accepted Answer

Precocious puberty is the onset of puberty before age 8 in girls or before age 9 in boys. It requires prompt evaluation as it can compromise final adult height and cause psychosocial challenges.

Question 5

What is delayed puberty?

Accepted Answer

Delayed puberty is defined as the absence of any puberty signs by age 13 in girls or age 14 in boys.

Question 6

Why does height increase rapidly during puberty?

Accepted Answer

The height growth spurt during puberty is driven by sex hormones — testosterone in boys and estrogen in girls. These hormones also eventually cause bone plate fusion, ending further height growth.

Question 7

What are the risks of early puberty?

Accepted Answer

Early puberty can reduce final adult height due to premature fusion of bone growth plates. It can also cause significant psychosocial and emotional challenges for the child.

Question 8

Can early puberty be treated?

Accepted Answer

Yes. GnRH analogue injections can effectively pause puberty progression, protecting final height and allowing the child to develop at the appropriate age.

Question 9

Can delayed puberty be treated?

Accepted Answer

Yes. Testosterone therapy (for boys) or estrogen therapy (for girls) can induce normal sexual maturation in patients with delayed puberty.
