WHY PUBIC HAIR?
Pubic Hair is one of those traits that once had an evolutionary value but now serves no practical purpose. We don't require ‘fur’ to stay warm, or protect us from the elements.
But pubic hair plays an important sexual role in human beings. We're born without it, as an indication of immaturity. As we mature, our bodies change, preparing us to fulfill our unique role in nature. Androgens signal the onset of puberty and the body's new capacity to reproduce. Puberty (derived from the Latin word puberatum (age of maturity) refers to the bodily changes of sexual maturation rather than the psychosocial and cultural aspects of adolescence.
Puberty is the physical process by which a child becomes an adult. Initiated by signals from the brain to the gonads (the ovaries and testes), it produce a variety of hormones that stimulate the growth, function, or transformation of brain, bones, muscle, blood, skin, hair, breasts, and reproductive organs.
