    Prior to puberty, the physical differences between boys and girls are restricted to the genitalia. During puberty, a wide variety of changes result in significant physical differences between the sexes. Girls typically begin puberty 1-2 years before boys and also finish puberty sooner. They reach adult height and reproductive maturity on average about 4 years after puberty starts. Boys start puberty later, but generally continue to grow and mature for about 6 years after its onset.
