"Some people may have the physical characteristics of both genders, a chromosomal disorder, or simply have ambiguous features. The condition is generally referred to as intersexuality, although an older term for someone with both male and female organs is hermaphrodite.
Dr. John Park, a pediatric urologist at the University of Michigan, said a likely scenario is a condition called androgen insensitivity syndrome. The person is genetically male but doesn't develop external male genitals and appears to be female, or the person can have both male and female physical characteristics."
in this case she may have testes inside her body, but they never developed, and they're not producing testosterone, so what is the issue?
