Though not all precocious puberty has a specific pathological cause, it may indicate a serious medical problem and is thoroughly evaluated. In most cases, the cause of precocious puberty cannot be identified. "Central precocious puberty" or "true precocious puberty" stems from early activation of the hypothalamic-pituitary-ovarian axis.
Adrenarche begins on average between age 5 to 8 in girls and between 7 and 11 in boys, and precedes puberty by about 2 years. [1] [4] [5] Unlike the physical changes that occur during puberty, adrenarche is primarily an emotional and psychological stage of development. [6]
Starting puberty significantly early — younger than age 8 in girls, 9 in boys — may have health effects lasting into adulthood, including higher risks of breast cancer, diabetes and heart disease.
The point at which a child becomes an adolescent is defined by the major onset of puberty. [2] [15] However, in some individuals (particularly females), puberty begins in the preadolescence years. [19] [20] Studies indicate that the onset of puberty has been one year earlier with each generation since the 1950s. [21]
A study has revealed that serum progesterone concentrations in boys (10 days to 18 years old) with 21-hydroxylase deficiency reached levels up to 10.14 ng/mL, i.e. similar to female luteal values, while in the control group of boys average level was 0.07 ng/mL (0.22 nmol/L), with values ranging from 0.05 to 0.40 ng/mL.
