Genital organs changes:•Mons pubis, labia majora & minora:increase in size.•Vagina:1.length: increase, appearance of the rugae2.Epithelium: thick, stratified squa-mous, containing glycogen3.pH: acidic.
• Uterus : enlarges.Uterus / Cervix : 2 / 1 • Ovaries: 1.Increase in size, almond shape 2.300-400 thousand primary folli- cles at menarche ( 2 million at birth) Genital organs changes:
Differences between male and female puberty • Onset in girls at 10-14 years old while in boys at 12-16 years old • Breast development in girls while boys increase in the size of the testicles • While in girls ovaries begin to grow and in boys it’s the testes that begin to grow • Onset of menstruation occurs only in girls • There’s difference in body shape and fat distribution in boys and girls. While boys develop heavier bones, nearly twice skeletal muscle in girls the pelvis and hips widen. More fat distributed to breasts, hips, buttocks, thighs, upper arm and pubis. • Voice changes occur in boys.

FEMALE PRE- COCIOUS PU- BERTY
Definition:It means menarche or appearance of any of the secondary sexual characters before the age of 8 years.
Types: 1 - True precocious puberty . 2 - False (pseudo- precocious puberty). 3 - Incomplete precocious pu- berty .
1. True (central ,cerebral) precocious puberty. It is due to increased pro-duction of pituitary go-nadotrophins.
2. False (peripheral) precocious pu-berty •It is of peripheral origin. •It is due to secretion of sex hor-mones; (estrogen or androgen)which is not dependent on pitu-itary gonadotrophins as in case of estrogenic or androgenic ovarian tumors.
•False precocious puberty may be isosexual or heterosexual.•A girl who feminizes early is defined as having isosexual precocious puberty•A girl who virilize early is defined as hav-ing heterosexual precocious puberty.(female pseudohermaphrodite)2. False (peripheral) precocious pu-berty . -
3. Incomplete precocious pu-berty•In this case only one pubertal change as breast developmentis present be-fore the age of 8 years without the presence of any other pubertal changes and in absence of increased estrogen production. •The other pubertal changes occur at the normal age.
Incomplete forms of precocious puberty include premature the- larche (unilateral or bilateral), premature pubarche and pre- mature adrenarche with ap- pearance of pubic and axillary hair. 3. Incomplete precocious pu- berty
