Gender puzzle

Transsexuals like "Kevin" are now under the scientific microscope because they may hold the key to the gender puzzle. By studying people on the gender extremes, scientists believe they may discover the genes that determine everybody's gender.

 

"Kevin" has already made legal history. His court case is believed to have been the first that relied on "brain sex" as a determinant of gender. He was born in a female body but as an adult underwent hormone therapy and gender realignment surgery. When his partner "Jennifer" became pregnant through IVF, they decided to marry despite opposition from the federal Attorney-General's Department.

 

As this documentary reveals, they wed despite a bizarre email from a department official and mother of four who warned that "marriage is not all it is cracked up to be". The department challenged the validity of their marriage in a landmark case. But the Family Court decided in "Kevin's" and "Jennifer's" favour.
