Sydney, July 8 (IANS) Researchers have stumbled on a vital discovery that could be the silver lining in a rare condition known as disorder of sex development. One out of 4,500 babies is born with ambiguous genital development that makes identification of the child's gender doubly difficult for parents and doctors - whether the child should be raised as a boy or a girl.

The new finding shows how an extra copy of a gene known as DAX-1, which regulates sexual development, halts the process of the male baby developing a testicle.
