Intersex is a condition one is born with in which their biological sexual  
characteristics and/or chromosomes do not indicate distinctly whether
they are male or female.  There are many variations to this condition.  
Sometimes the condition is not discovered until later in life.  Sometimes
parents of intersex children make decisions to have gender assignment
surgery while their child is very young.  This can cause problems later
and is controversial.  This condition should not be confused with
transgender.  With intersex the body is not always giving clear indication
of male or female.  With transgender the question is whether the person
(in mind and heart) is the same gender as their body.  For more
