After the onset of puberty, the mons pubis and the labia majora become covered by pubic hair.
From the en.wikipedia.org
The soft mound at the front of the vulva is formed by fatty tissue covering the pubic bone, and is called the mons pubis.
From the en.wikipedia.org
The mons pubis, labia, and clitoris are reduced in size in post-menopause, although not usually to pre-puberty proportions.
From the en.wikipedia.org
Coloration may change and pubic hair develops, first on the labia majora, and later spreading to the mons pubis, and sometimes the inner thighs and perineum.
