Gender Blender
This was the moment of truth. The ultimate test before the coronation. A deacon would extend his hand below the robe of the future pope and check for the presence of two testicles. Middle Ages legend has it that this rite was started after Joan, an Englishwoman and a cross-dresser, managed to get elected pope in 855 but was discovered two years later because of an ill-timed childbirth.
Will we soon be witnessing such surreal examinations in our city halls? After all, if the Constitution will allow only marriages between a man and a woman, the county clerks had better make sure that they are issuing licenses legally. Patting down the two male organs would ensure an absolute certainty of sex identification. Or would it?
In reality, sex isn't so straightforward. Let's take testicles as a defining characteristic of a man. Are individuals with only one testis "real" men? The "two-testicles rule" would disqualify about 3% of male newborns a year -- about 4.5 million Americans total. Does one need to produce active sperm or eggs to be considered a man or woman? Adding a fertility criterion would eliminate millions more from both categories.
If conventional wisdom cannot easily define men and women by just a simple look at the private parts, science should help us distinguish between the sexes. Since 1921, we have known that women have two X chromosomes and men an X and a Y chromosome. This is the fundamental genetic distinction between men and women.
But still, it's been difficult to find clear-cut answers. Olympic Games officials have struggled with the science of "sexing" individuals for many years -- often after high-profile cases of gender confusion. In the 1936 Olympics in Berlin, U.S. runner Helen Stephens beat Polish runner Stella Walsh in the 100-meter sprint, winning a gold medal and breaking Walsh's 1932 record. The Polish press falsely accused Stephens of being a man. Ironically, after Walsh was killed during a 1980 robbery, her autopsy revealed male genitals. Decades later, Erica Schinegger, who won the women's downhill skiing world title for Austria in 1966, was two years later found to be chromosomally male and, as such, disqualified for the Olympics. Her case forced the International Olympic Committee to require all athletes to take a test counting the number of X chromosomes.
In 1990, scientists learned that a gene called SRY on the Y chromosome is what makes fetuses become boys and not girls. In 1992, the Olympic test was perfected to detect the presence of the SRY gene.
